Proper roof ventilation allows air to circulate in and out of your home during all kinds of weather conditions; without it, moisture has no where to go which can cause many problems. Having proper ventilation has many benefits for you and your home, and is essential to having a healthy and long-lasting roof. Here are some benefits of proper roof ventilation:
1. Keeps energy costs down
2. Reduction of heat build-up in the summer
3. Eliminates trapped moisture that causes mold, mildew, wood rot, drywall damage, peeling paint and warped siding
4. Keeps roof decks cool in the winter to protect against ice dams
5. Extends the life of roof shingles
6. Keeps your attic cool and dry
Achieving Proper Roof Ventilation
To create a system which properly ventilates air throughout your home, you must consider the conditions in which you live and the air that comes in and out of your home. The mid-atlantic region gets snowfall in the winter that can cause roofing problems without a proper ventilation system. The region also has warm weather that if heat gets trapped, will cause energy bills to soar. The best choice for your roof depends on the size and shape of your roof, and the layout of surrounding trees, wires and other objects.
Moisture also builds up in your attic due to inside sources. Appliances such as washing machines and dish washers create moisture which can also damage your home if you don’t have proper ventilation. This means that no matter where you live, proper ventilation is important for you and your home.
Asphalt roofs tend to radiate heat into attic spaces, radiant barriers that can be installed in the roof rafters will help heat escape. Well-vented attics minimize the risk of ice dams that have the potential to clog roof drains and cause damage.

Top 10 Mistakes in purchasing new roof
It’s always best to shop around when you’re making such a big investment on your roof. But just looking for cheaper price is not a good way to shop. Look at the product details, warranties and about the future roof repair costs.
1. Shopping around for price
The price to install or repair a roof will vary depending on the stories, size and location of your home. Cost alone will not determine quality. Professionalism and quality workmanship should also weigh heavily on your decision. If you shop around for prices and notice that a company is well below the average, there may be a reason why.
What is the total price of the job? Does this include sales tax? When are the payments due? Does the price include removal of the old roof? Any hidden costs?
Check the insurance of every company doing work at your home. Because of the dangers inherent in working on the roof, company should carry both workers’ compensation and liability insurance. Since the cost of the insurance is high, some companies do not carry it. This practice is a shortcut some companies take to underbid the competition.
2. Basing your buying decision on the quickest to respond or because a company can "start right away".
A company that is too quick to respond may not have enough business.How long has this company been in business? You want to make sure that this company will still be around in case you have problems with your roof. There are roofing companies which carry extended warranties from manufacturers; this means that in case if the company is not in business, manufacturers will pay for all your work. So go for a company that has certified.
Number of years of roofing experience for installers? and the safety record.Make sure the company is licensed, bonded and insured in your area. Don’t hesitate to ask the roofing contractor for proof of insurance. In fact, insist on seeing copies of his liability coverage and worker's compensation certificates. Be sure the coverage runs through the duration of the job.
Does the company offer references of past work? Obtain customer references and check them. Ask about the company's stability, reputation, record on completing jobs on time and quality of work performed.
Check out all companies with your local Better Business Bureau(www.bbb.org)
Make sure you get a contract. Insist on a written proposal and examine it for complete descriptions of the work and specifications, including tasks the roofer will perform, types of materials, financial arrangements, and guarantees.
3. Getting a discount for signing the contract "tonight" or other high-pressure sales tactics.
This forces the homeowner to make a quick decision, so as not to miss the “unbeatable price.” No matter how good the price may seem, do not buy a roof from a company that asks you to make a decision before you are ready. Granted, recent hurricanes have caused uncertainty in building materials availability and pricing, however a reputable company will have relationships and access to quality products for 2 or more weeks from the time they provide you with a quote. There is an outside chance that a contractor may have a "sudden" opening in their work schedule and offer an incentive to keep their crews working, however the more reputable companies do not have a significant amount of discount or wiggle room in their cost. If they offer more than a 10% discount, one might question their margins in the first place. Additionally, some companies will more heavily incent their salespeople to get a contract signed the same day. The bottom line is, take your time when making any large purchase, such as a new roof. Does your homework, talk to references, and sign when you are comfortable that you've made the right choice.
4. Signing the deal because you like the sales person (or not signing it because you don't).
Although you may feel a certain comfort level with a sales person, it should not be your sole reason for making a purchase. A truly good sales person will know their products and the overall installation process very well, which should give you a level of confidence. However, the sales person is not the one who will be doing the roof repair or installation. Find out who will, and their experience. Ask for references and ask to see examples of similar installations. Be wary of a sales person who cannot provide real references from CURRENT customers.
5. A deal too good to be true probably is – check:
Have your contractor list the roofing manufacturers with which his firm has licensed or approved applicator agreements. Most materials require special application expertise in order to achieve a quality roof system that will last. Quality materials will be backed by a manufacturer’s warranty as well.
What is the warranty? Both quality materials and quality workmanship/installation should come with their own warranties. Ask what warranties are available for both.
In addition to the cost of labor and materials, ask if there are any hidden additional costs, such as old roof removal, dumpster rental, heavy equipment rental (e.g. a crane to lift heavy materials such as slate onto a high rooftop), and plywood replacement (for unknown/hidden rotten wood beneath old shingles).
A reputable company will be able to provide recent references in the general vicinity of your home, or for an installation similar to yours. Get the reference and actually make the call!
6. Purchasing the roof based on warranty alone.
The length of a roofing warranty should not be the primary criterion in the selection of a roofing product or system. The warranty does not necessarily provide assurance of satisfactory roofing performance. (source: nrca.net)
Make sure that the warranty covers all materials and workmanship. Some roof warranties require you to have at least semi-annual maintenance inspections. Look for manufacturers' warranties that provide full coverage for labor and materials.
According to a consumer advisory bulletin by the NRCA, consumers are wise to look for manufacturers who clearly and specifically state in accompanying literature and warranty verbiage what maintenance is not only recommended but also required during the projected service life of the roof and its warranty term.
There is a common misconception by roofing consumers that long-term warranties are all-inclusive insurance policies designed to cover virtually any roofing problem, regardless of the cause or circumstance. Roof warranties typically do not warrant that the roof system will not leak or is suitable for the project where it is installed. Even the most comprehensive manufacturer warranties that cover material and workmanship generally provide only that the manufacturer will repair leaks that result from specific causes enumerated in the warranty. A material-only warranty typically provides only that the manufacturer will provide replacement material. (source: nrca.net)
You can compare manufacturers’ warranties with the roofing materials guides published annually by the NRCA (National Roofing Contractors Association).
7. Using contractors with no office staff.
There is no shortage of contractors running one or two-man shops in any town. While they may be fine for smaller jobs, when you are making a large home improvement investment, beware of any contractor who you cannot get in touch with during normal business hours. A reputable company will have an office staff available to answer any scheduling, materials or billing questions you may have. If you call a contractor and consistently get an answering machine, know what you may be getting yourself into. If you have difficulty reaching them when you are going through the estimating process, where will they be if you have a problem?
8. Mistaking advertising for quality.
Look in any value-pack mailer, coupon clipper magazine or even radio and television and you'll see and hear many companies in your area vying for your business. While it may be impressive that they have the means to advertise in high-priced media, do not mistake advertising for quality. There is nothing wrong with finding a company through the media, but do as you would with any major purchase – do your homework. Compare pricing, check references, and check workmanship. A reputable contractor will provide you with access to all of the information you need to make an informed decision.
9. Having a friend do the work.
Having a friend -- one that is not a licensed roofing contractor working for a reputable roofing company –is wrought with uncertainty. Even if this person is "handy", have they ever installed a roofing system? Do they know what areas of a roof are most vulnerable and why? Do they know how to properly ventilate the roof? No to mention, any work done by an unlicensed contractor will not include a warranty. The cost of roofing repairs may be high and you don’t want to commit to such a major investment without a warranty.
10. Doing the work yourself.
Big box retailers will tell you that you can do it (and they can help!), but beware! Roofing in particular is tricky business. There are obvious safety issues, as well as structural installation issues that should only be performed by a licensed professional. Professional roofing contractors are trained to safely and efficiently repair or replace a roof. Novices can harm a roof with improper roofing techniques and severely injure themselves by falling off or even through a roof in need of repair of replacement. Homeowner maintenance should be confined to roof inspections in both the fall and spring to check for cracked or curling shingles, and to cleaning rain gutters filled with dead leaves and other debris. If you must see the roof for yourself, use a firmly braced or tied-off ladder equipped with rubber safety feet. Wear rubber-soled shoes and stay on the ladder (and off the roof) if possible.
What to expect before shingle roof replacement
You might have got information about roofing contractors through neighbors, friends, phone books, sign boards and search engines like Google, Yahoo. After you have found useful information you might try to reach the contractors to request service and most of the contractors will schedule appointments for the roof inspection and to give you an estimate. To give an estimate, a contractor will come to your house to inspect your roof. He’ll come up with a number that factor in the cost of materials and labor, including the cost of stripping and throwing away the old shingles. The estimate should include the cost of removal and disposal of the old roofing material. If not, ask about this to avoid surprises. There is a chance that there will be some unforeseen costs in the project, so it is good to avoid as many of these as possible. After the visit, they will send you a written contract. A contract from a roofing company should include a description of what is to be done, as well as when it is to be done and a schedule for payment. Having it all in writing can protect the homeowner later on. Be sure to shop around before settling on a specific contractor, as prices can vary considerably unless you have found a trust worthy roofing company.
Once you’ve chosen your roofing materials and your contractor, it’s time to set a date for the project to start. The roofing contractors suggest you available and rain free day to work on your project. The actual work of replacing the roof can take anywhere from a few days to a few weeks, depending on the size of the roof. You should plan to have someone at home while the work is being done. If they have any questions or discover any additional problems with your roof, it helps that you are home to discuss things with them. If not leave a best contact number to reach you any time while doing the work to discuss such problems.
Before the workers arrive, it’s good to remove any items that may get in the way of their ladders. Only few roofing contractors remove tree branches that come in their way ask before they start working. Climbing on roofs can be dangerous, even for professionals, so it’s best to stay out of their way. First, the roofers rip out all the old roofing shingles and replace any rotted or damaged wood in the roof. Next they lay a base, and then they lay the shingles. Roof work is noisy. Expect to hear a lot of hammering as well as people running around all over your roof. It’s not really an invasive home repair. You won’t have workmen coming inside your house. As long as you don’t mind the noise, it’s not much of a hassle.
When the old shingles have been stripped, any unshingled portions of the roof should be covered with a tarp overnight to protect your home in case of rain or overnight storms.Once your new roof is completed, make sure the workers have cleaned up all the debris that has fallen. When a roof is replaced, the workers usually toss the pieces of the old roof onto the ground or into a dump truck as they’re working. Once the bulk of the old material is disposed of, responsible companies will clean up after themselves to ensure customer satisfaction. They usually have a magnetic broom that picks up all the nails and other materials that can be hazardous as well as unsightly. You may find a shingle or two in your yard after wards, which is perfectly normal.
When you have roof work done, you should never pay anything up front. You always pay after the job is completed. This is standard procedure. All reputable roofing companies operate this way.
Pay attention to the roofing estimate
I have seen customers spending days to months, sometimes even years of time in getting roofing estimates from the contractors. I wonder why do they need that many estimates. Though they need an immediate service they wait to get all the estimates they have requested. I am not saying not to get estimates but get the estimates of 3 to 5 and select the estimates that best suits to your service.
Especially when are requesting for a roof repair, just don't waste your time in getting estimates and making your problem worse. Go for an estimate that is well written and contractor who has the proven, trusted service record.
Most of the customers concentrate on getting multiple estimates from the roofing contractors not on the roofing estimate specifications. They go for the estimate that is cheap, which is a biggest mistake. Since all roofing contractors may not be giving you an estimate for the same type of roofing materials, warranty. Check the specifications of the estimate and select an estimate that is providing you the best service within the budget.
Choosing the best option but not paying attention on the estimate is no different than signing up with the first service provider you find. Keep the following factors in mind when you obtain a roofing estimate. An estimate should be formal and should have the name service provider, tasks must be clearly written, roofing materials, warranty information. A few figures roughly sketched on a rough piece of paper is not an estimate.There are roofing contractors who provides you a computerized estimate with the diagrams and specification of work. Remember that those service providers who offer vague estimates often make use of this characteristic to increase the cost. On the other hand, a service provider who offers a specific roofing estimate is a much better bet.
The next factor that you should consider is whether the estimate clearly covers each and every task that you want to be done. There are many service providers over very low estimates by skipping major tasks. A roofing estimate that simply covers the cost of installing the tile but does not cover the cost of the tile is of no use whatsoever. Make sure each and every specific task that you wish to carry out is clearly specified in the estimate.If you want to make sure that you deal with the most affordable service provider, you should get estimates from various service providers. It is your right to get an estimate of the work to be done at zero cost. Hence, never pay anybody just to get an estimate of the work to be done. Dealing with such expensive professionals is not the smart way to proceed.
The advantage of using the web is that you can compare the various estimates you have received and determine whether it is indeed accurate and reliable.

Thuderstorms, hail, tornadoes damage roof
All thunderstorms are dangerous. Every thunderstorm produces lightning, which kills more people every year than tornadoes. An average of 80 people is killed and 300 injured each year by lightning. In addition, heavy rain from thunderstorms can lead to flash floods, which are the number one cause of deaths associated with thunderstorms. Strong winds hail and tornadoes may be associated with some thunderstorms. Lightning also causes many fires each year.
Even strong structures may not be able to withstand tornadoes, and some tornadoes have been seen to rip asphalt from the ground. The stronger the wind speed, the more likely the sight of heavily damaged buildings and grounds. An F0 tornado will not cause much structural damage; you may see damaged tree branches or roofs, and windows broken by flying objects. Anything that might be lifted or moved by regular winds may be affected. As wind speed increases, stronger tornadoes can actually lift houses from their foundations, as happened in the Jarrell, Texas, tornado of 1997.
Hail causes more than $1 billion in damage to property and crops each year. You do not want to own a new car dealership when there is thunderstorm with large hail. The flash of lightning and the boom of thunder occur at the same time. Lightning is seen before the thunder is heard, however, because light travels faster than sound.
By counting the number of seconds between the lightning flash and the sound of the thunder, you can tell roughly how far away the storm is. Every five seconds represents one mile. If the storm is a mile away, the lightning flash reaches you virtually instantaneously, but it takes about 5 seconds for the sound of the thunder to reach you.
Thunderstorms affect small areas when compared with large storms like hurricanes and winter storms. The typical thunderstorm is about 15 miles in diameter and lasts for about 30 minutes. Nearly 1,800 thunderstorms are occurring at any given time around the world, and more than 20 million lightning strikes a year.
In the southeastern and western states, most thunderstorms occur during the afternoon. In the Plains states, thunderstorms are common in the late afternoon and at night. Tornadoes are the most violent type of storm, with wind speeds reaching up to 300 miles per hour. Tornadoes develop from powerful thunderstorms and appear as rotating, funnel-shaped clouds.
Check the size of the hail if possible. If the hail is one inch to one and a quarter inches in diameter, then the hailstorm may have damaged your roof. As a point of reference, hail that causes damage is usually about the size of a half dollar. After a hail storm it can be hard to see the damage to the roof, but experts say the best thing to look at is vents and the gutter down sprouts. So after a hail storm, have a walk around your house to inspect for damage. After you get close enough to your roof to inspect the shingles, look for hail marks. On asphalt shingles these look like dimples or dark spots where the hail has hit on the shingle. You may even see parts of the shingle edges that have been knocked off. Note any areas where you see the asphalt underlayment exposed. This is the liner between your shingles and the roof boards. Fresh damage from hail often has a shiny appearance because the asphalt granules have not had time to weather and dull.
When it comes to a tornado it doesn't matter what the intensity of it is if your house is not properly built to withstand it. If your house is not wind-proofed it can suffer a lot of damage. Inspect the roof of your house. If you are uncomfortable with checking your own roof then have someone come out and look at it for you. The connection between your walls and your roof needs to be strong enough to resist the uplift caused by the wind of the tornado and they should be secured with metal connectors.
It is advisable, that after each natures disaster check your roof to see if there is any damage caused. If you are not able to identify the damage then call for a roof inspection at 281-883-2692.

Ventilation of the home attic is important for two reasons. During the summer, excess heat that builds up in the attic during the day results in high energy costs for cooling. Also, moisture produced within the home may move into the attic if ceiling vapor barriers are not used. If this moisture is not exhausted from the attic it can condense and cause insulation and construction materials to deteriorate. Thus, temperature and moisture control are the major reasons for providing attic ventilation.
The amount of insulation using these days was not enough, especially in summer it might cause to increase utility bills because of the 90 degrees temperature, hot breeze.
Roll Roofing- Installation and repair
Many people want to install roll roofing due to the fact that roll roofing is an inexpensive alternative for many roofing needs. It is much more convenient and easy to install than other roofing choices. If you want to install roll roofing, then you will be pleasantly surprised to know that there is only one sheet of roll roofing needed, compared to three layers in other roofs.
If a roof is almost completely flat, then it is recommended that you use what is known as double coverage selvage. Before you install roll roofing, you should understand that this type of roofing is more delicate than other roofing materials. In fact, if the weather becomes too cold, it may crack or become damaged. Best results are achieved when it is installed at temperatures of 45 degrees F or above. If you wanted to install roll roofing in a cold climate, you can successfully accomplish this, as long as you warm the roof rolls first.
It is very important before you install roll roofing that you make sure each piece is completely flat and smooth. If It isn't, or if your roll roofing has a dried puckered look or is curling, then you will need to straighten it.Installing roll roofing is so easy that just one or two people are needed to complete it. You can run the roll roofing either horizontally or vertically. Vertical installation is the best option on really steep slopes. Either way, the seams need to be overlapped by 2 inches and sealed with roofing cement.
You can accomplish this by straightening out the pieces, and then cutting them into sheets that are between 12 or 18 feet in length. After you successfully cut the pieces, you can stack them so that they will dry. It should take anywhere between sixty minutes to one hour for your cut pieces to return to a completely flat state. Roll roofing is a suitable choice for roofing material because it can last between 6-12 years. It is made out of the same substance as shingles; asphalt coated fiberglass or felt. IT installs with very little effort and in an expedient manner. If you want to re roof a shed, the choosing single layer roll roofing is recommended. You can use single roll roofing on a roof that has a flat roof, not one that has an inclined slope.
Roll roofing is made of similar materials as shingles, but it is cheaper and easier to install. Since it is not as attractive or as long lasting with only a 5 to 12-year life span, roll roofing is generally used on flat roofs, sheds, or areas that are not seen. Roll roofing is quick to unroll, which is why it is cheaper and faster to install.
Roll roofing does have some disadvantages. One is the shorter life span. Another is the single layer of protection that it offers as opposed to three layers when you use shingles. It is also more susceptible to cracking in temperatures below 45 degrees. You must carefully sweep the roof to keep small sticks or rocks from poking through the roll roofing. The last inconvenience is having to use roofing cement to seal the seams and nails.
Factors to keep in mind while selecting or specifying a roof system
A quality roof depends on two essential elements: excellent materials and superior workmanship. Most of the manufacturers have the contractor programs to help assure customers that you will get the best possible workmanship when choose the materials from that manufacturer and they also offer an extended warranties which cover workmanship and labor costs for a certain time period. They choose the roofing contractors who have met the strictest criteria relating to financial credibility, workmanship history and sound practices, including proper licenses and appropriate insurance.
Keep the following factors in mind when selecting or specifying a roof system.
1. Choose the highest possible quality materials from an established manufacturer with an excellent reputation for integrity.
2. Compare similar products. Evaluate the technical data provided by the manufacturer. Compare the weights, thickness and ASTM test results. Quality does make difference.
3. Remember the value of the life cycle costs. The money saved today on a low cost roofing system can be more than offset by the need to re-roof sooner as the result of poor performance leading to leakage or premature failure. If you are roofing over an existing roof now, a tear off will be necessary next time around, greatly increasing the cost.
4. Consider the manufacturer's warranty. The length of the warranty term(in years) helps gauge the superiority of the system selected. Generally, the longer the warranty, the better the system. Is a guarantee which covers not only the material but also the contractor's workmanship available for the roof system selected? Whether or not the owner specifier opts for this coverage, it is also an indication of the quality of the roof system selected.
5. Proper value. Think about the future. Is the manufacturer's warranty transferable to a new building owner?
6. How committed is the roofing materials manufacturer willing to be? Does the manufacturer, as an option to the owner, have an approved contractor program in place? If an enhanced warranty which includes workmanship is selected, will the manufacturer inspect the roof project? Remember that in any roof system, proper installation is the most important factor.
7. Consider energy costs. Keep in mind that white mineral surfaced cap sheets, light colored gravel surfacing or roofs coated with reflective roof coating will help reduce interior cooling costs.
8. Choose a System manufacturer. Consider manufacturers like CertainTeed which provides the key elements of the roof system -insulation, adhesives and coatings, membranes and fasteners.
9. Consider building code requirements. Keep in mind many local and state governments have specific guidelines for specifying roof systems.
CertainTeed is a leading manufacturer of commercial and residential roofing products with great warranties on selected roofing contractors. We are proud to announce that Rocket Roofing Corp Company is the one of the credentialed roofing contractor of CertainTeed.
Stains on your roof?
Walking into your home you look and wonder why your roof has stains? It's that dark staining that looks like someone spilled coffee up on your roof. This usually caused by mildew or algae in years past. Mildew is a by-product of fungi and mold. "Roof Algae" has grown from past 15 to 20 years.
Why now? Why my Roof!!
A large number of homeowners who are experiencing these roof stain problems are doing so for the first time. Even though they live in areas where the climate has not changed, the problem appears out of the blue.
In years past, the roof algae simply didn't have a food source. Until shingle manufacturers lowered production costs, and provided roof algae with its favorite food, limestone. Today's fiberglass shingles contain massive amounts of food that the roof algae love to eat.
How in the world does limestone get into fiberglass shingles you might ask? It's simple. The limestone is added to the asphalt mixture as a filler or thickener. Years ago, this was not necessary, as an organic felt mat was used as the base for the shingles. This mat was saturated with asphalt and then coated with granules. Because of the absorptive qualities of the mat, it was able to soak up enough asphalt to give the finished shingle sufficient weight. The materials used for the mat were derived from the cotton rag scrap market.
Well, about 20 years ago this rag market dried up because of the widespread introduction of synthetic textiles such as nylon and polyester. The shingle manufacturers scrambled and decided to use fiberglass as a mat.
However, a problem quickly arose. The thin fiberglass mat didn't absorb asphalt like the old organic mat. Something had to be added to the asphalt to increase the weight of the shingle. They decided to use limestone because it's plentiful and cheap.
As a roofing contractor I always suggest customers to go for a roofing contractor who is certified an dcan offer lifetime warranty on roofing materials and up to 20 years of warranty on workmanship and labor.
Until recently, homeowners needed Professional Roof cleaners to eliminate the roof algae and remove roof stains. Recently, roof cleaners have been made available to Do-It-Yourself homeowners who want to save the expense of the roof cleaner. A variety of roof cleaners exist. Choose wisely, you want a cleaner that is quick, simple and effective.
Is GenTite EPDM, TPO residential roofing system is a good choice in Houston, TX?
GenFlex Roofing Systems is well known as a commercial roofing manufacturer. But recently, it has introduced its GenTite Residential Roofing systems. Their knowledge and experience in commercial roofing systems help them in building a high performance roof that is easy to install roof.
 |  |
Any house owner who wants to have a patio, porch, shed dormer, balcony or carport attached to the home, their roofing contractor suggests them having a low slope roof. Low slope roofs are not water tight roofs like how asphalt shingles shed water. If you don’t select a water tight roofing system, water will penetrate through your roof.
GenFlex Roofing Systems makes both EPDM (Ethylene Propylene Diene Monomer) and TPO (a high quality thermoplastic polyolefin) membranes. Since the products of GenFlex are cooler in summer times. It is a good choice in Houston, TX. As a Texas resident you are not suppose to use black color membrane on your roof. SO we will suggest you to go for a white roofing membrane which saves energy bills. GenFlex white TPO products meet the stringent criteria of the LEED program and California Title 24 Standards.
GenFlex EPDM is a high-quality rubber membrane that is resistant to tears, impacts, punctures and normal foot traffic. Normal structural movement has limited effect on its integrity. This membrane provides excellent resistance to ozone and ultraviolet light exposure.
Like EPDM, GenTite TPO roofing systems are designed for durability and to withstand extreme environmental exposure. The bonus is the reflectivity of the white membrane is proved to keep solar heat out of buildings, increasing energy savings. In some geographic regions, GenTite TPO “cool roof” systems stay 50 to 60 degrees F. cooler at peak times than traditional roofing membranes.
When you are remodeling your house, you should be aware of is that you can’t go directly construct over an asphalt-based roof. Before making an decision of construction these residential membranes, please consult a local roofing contractor or company to find if it is a good choice for your building structure or is it meeting your criteria or not.
Is EPDM a best choice in Flat Roofing Membranes?
EPDM(ethylene propylene diene terpolymer) formulations are versatile, and many EPDM materials produced have a wide range of use in automotive, industrial, and commercial applications. EPDM roofing has been used as a roofing material in North America since the early 1960s. EPDM is a synthetic rubber material that can be formulated with extensive flexibility for use as membrane sheet roofing. EPDM membranes exhibit good resistance to ozone, UV rays, weathering, and abrasion. EPDM also has good low temperature flexibility. EPDM is resistant to some acids; alkali's; and oxygenated solvents, such as ketones, esters and alcohols. On the other hand, exposure to aromatic, halogenated and aliphatic solvents, as well as animal and vegetable oils and petroleum based products, should be avoided to prevent membrane swelling and distortion.
The EPDM rubber roofing has been an appealing choice for both re-roofing and new roof construction projects in the low-slope commercial roofing industry for over 40 years. The EPDM rubber roofing membrane is an elastometric polymer synthesized with clay for fire resistance and dimensional stability, carbon black to increase tear strength and resistance to UV rays, process oils for flexibility and curing agents for vulcanization. EPDM sheets available in thicknesses of 45, 60, 75 and 90 mils.
The popularity of EPDM roofing in market, made EPDM manufacturers remain committed to continuous product innovations. The innovations of seam tapes in the 1980s to replace liquid adhesives has resulted in greater productivity for the contractor and enhanced performance for the roof system and building user.
Advantages:
1. It retains physical characteristics throughout its service life.
2. They are resistant to UV light, high and low temperatures
3. The EPDM rubber membrane offer design flexibility
4. Easy to install.
5. Great warranties up to 30 years will save your investment on the roof
6. You can install EPDM over an existing roof system.
While inspecting EPDM roof
When inspecting an existing EPDM roof, roofing contractor, facility managers should look for these conditions:
1. Disbondment at seams, laps and splice areas which can result from ppor workmanship, delamination, physical damage and deterioration over time.
2. Holes or punctures in membranes as result of fasteners backing out of substrates or contact with heavy objects
3. Wrinkles in the membrane that restrict water flow, caused by inadequate attachment, curling of insulation or contraction of the membrane after application
4. Shrinkage of sheet membranes
5. Dimensional stability of the insulation that deforms or otherwise puts undue stress on the membrane
6. Defects in ballast such as broken, deteriorated or missing pavers, exposed membranes due to displaced ballast or ballast with sharp edges
7. Defective or improper repairs in the roof membrane
8. Improper application of EPDM sheets that were not allowed to relax or recapture themselves , before perimeter securement.
Skylights on your roof!!!
A skylight is a glazed window that fits on your roof. It can be flat or domed, fixed or vented. Some vented skylights operated by an electric motor, while others open and close manually.Skylights come in all shapes and sizes and have been installed in homes in all types of climates. Skylights add light and brighten up dark and dreary rooms or hallways and can make your house very cheery and bright. If you are considering installing a skylight, there are a number of factors to take into account. Location is important especially if you are trying maximize the amount of light that comes in, heating or cooling effects in winter, aesthetic impacts, construction changes to your roof and the and overall light improvement in the home.
Roof skylights are not only great to look at; they offer many benefits as well. The value of your home will increase, and your rooms will benefit from the natural light. Your energy bills may even drop as a result. Here are a few design choices to consider if you have a flat roof.
3 Stylish Flat Roof Skylight Designs are
Combination Roof Lines
If you have an area that is partially flat, and partially pitched, a combination skylight can add a unique look. You can find these to use with almost any pitch. They are designed to be placed on both the pitched area as well as the flat roof area. This looks great in entryways and in sunrooms alike.
Pyramid Skylights
If you want a way to add some depth and dimension to your flat roof, consider a skylight with a pyramid design. These are more difficult to install since they will require a new framing system around the sky lighted area. The extra effort is well worth the look you will achieve.
Tinted or Stained Glass
For an extraordinary looks consider using tinted or stained glass. A flat roof will accommodate the colored glass well since there isn't any pitch involved. You won't have to worry about the pitch taking away from the beauty of the glass itself.
Skylights on your roof not only save energy bills, they are beautiful too. People are opting skylights in their new homes or renovations. Installing skylights in your home is a relatively easy way to add warmth and value to a home. If you're building a brand new home, it's easy to include them in your initial plans. If you plan to add them to an existing home it will be well worth the effort and the investment. One of the biggest advantages to installing skylights in your home: they can transform an average, ordinary home into an extraordinarily-livable space. Skylights bring life by bringing light into your house. This natural light not only allows you to use darker areas in your house, they make them appear larger. These also save your electricity bills.
Skylights can be cracked or even broken by heavy impact from falling branches, windblown debris, or other accidents. If this is the case, repairs should be conducted by a professional, as skylights can be a hazardous and grueling process to try and repair or install without the required experience and tools. If you have a moving skylight, whether or not it is mechanically raised and lowered, the gears that move the skylight can jam.
Many skylights appear to be leaking in winter or rainy season. During the winter on very cold days, frost may form on the inside of the glass. This can be caused by high humidity in the home and cold weather. As the sun warms the roof during the day and in particular the frost on the skylight window, the frost will thaw and run down the sides of the walls inside the well of the skylight. Over time this can cause discoloration and even damage to the walls and even the floor below if there is very high humidity in the home. A simple solution is to control the humidity level in the home.
A more serious concern is the buildup of ice on the roof also known as “ice dams”. An ice dams can be formed on a roof below a skylight when snow builds up, on or around the skylight. Since the skylight has a lower insulation factor that the surrounding roof, snow on the skylight can be melted from the heat transfer through the glass and the sun. As the snow melts, the water will begin to flow down the skylight onto the colder roof, at which point it freezes due to the colder temperature of the roof. If sufficient ice builds up, and ice dam has formed and prevents the dissipation of the water causing it to seek other paths as it follows gravity. Water can back up under shingles and into the attic causing a great deal of unseen damage in the attic before it is finally exposed in the lived in portion of the home. If a spring thaw occurs, the homeowner can experience significant leakage into the home caused by the ice dam and the subsequent damage. The solution can be relatively simple. Constant vigilance and removal of any snow build up on or just below the skylight will usually prevent ice dams and the subsequent leakage. Homeowners who do not want to get up on a slippery roof can purchase a “roof rake” attached to a long flexible pole and rake the snow off the roof while remaining at ground level. A few minutes work may eliminate significant damage and inconvenience from a serious roof leak.

Frequently asked questions in roofing or about roofing
General Roofing Questions
Q: How do I know if my roof has problems?
In most cases, roofing problems are discovered after damage has occurred from a leak. However, not all leaks produce visible damage immediately. Some leaks can occur for up to a year before showing any signs of damage. To avoid this hidden problem, it is important to have your roof inspected at least once a year or after harsh weather events by a qualified roofing contractor. All too often, roof system problems are discovered after leaking or other serious damage occurs. Periodic (twice-a-year) inspections often can uncover cracked, warped or missing shingles; loose seams and deteriorated flashing; excessive surface granules accumulating in the gutters or downspouts; and other visible signs of roof system problems. Indoors, look for cracked paint, discolored plasterboard and peeling wallpaper as signs of damaged roof areas. For example,you may see excessive granules running down the downspout, shingles in the lawn, or excessive curling and cupping of the asphalt shingles on the roof or on flat roofs you may notice cracks or holes in the seams of the roof or flashing. Exposed nail heads are another place where water can get in and cause damage. You can also check for a ring of dirt or discoloration to the rocks or gravel that may signify a low spot in the roof where water tends to puddle. Check these spots for signs of cracks or holes as well.
Q: How can a homeowner prevent roofing problems?
Most roofing work should not be a do-it-yourself project. Professional roofing contractors are trained to safely and efficiently repair or replace a roof. Do-it yourself can harm a roof with improper roofing techniques and can harm themselves by falling through a roof even falling off a roof.Once a year inspections by a professional roofing contractor can discover cracked, warped, or missing shingles, loose seams and deteriorated flashing, excessive surface granules accumulating in the gutters or downspouts, and other visible signs of roof problems. Indoors, look for cracked paint, discolored plasterboard, and peeling wallpaper as sings of damaged roof areas.
Q: If my roof leaks, will I need to have it totally replaced?
In some cases, no. Leaking can occur because some flashing have come loose or because a section of the roof has been damaged. A roof failure, on the other hand, is generally irreversible and occurs from improper installation, choice of materials, or from the installation of a roof system inappropriate for the home or building.
Q: The Cost and Length of Roof Inspection in Houston?
The average cost of a roof inspection in Houston is $300 and may take, more or less, about a day to week to set up a time both you and the roofing contractor have free. You may get lucky and find a contractor who can look at your house right away, but you shouldn't necessarily take immediate availability as any indication of the quality of the inspector. Although a roof contractor should provide you with a detailed, written result of the inspection, you should plan on being there so you can ask questions about anything you don't understand. Without being able to talk to the contractor, you may not get as much as useful information as you could from your inspection.
Q: How can I determine my annual roofing cost?
Annual Roofing Cost = Total Cost (Materials & Labor)/ Life Expectancy of Roof System (in years)
Q: What are the different warranties available on roofs?
Usually roofs get warranties from the manufacturers and the roofing contractor who want to stand by their work(Optional). On roofing materials you will get the manufacturers limited warranty or lifetime warranty with limited transferable option. Workmanship and labor warranty on roofs is usually offered by contractors. But these days you can also get limited workmanship and labor warranty from manufacturers extended warranty programs. These extended warranties are available only when you choose a roofing contractor who is certified with that manufacturer.
Q: What should I check before I accept a roof warranty?
You should always read the terms on your roof warranty to see what the fitter is responsible for. Don’t forget you are paying money to the contractor for a roof warranty that will come from the manufacturer. You should get a third party to check the roof has been fitted properly otherwise your roof warranty will be invalid. If you are buying a building and you are told that there is an active rood warranty be sure to inspect it. If there are any actions required to transfer the warranty into your name demand that this be included as part of the sale and is the vendor’s responsibility. Some warranties demand that the roof be inspected and repaired (paid for by you) before the warranty can be exchanged.
Q: Can I cover over my existing roof?
Installing a roof over the top of an existing roof is generally acceptable under these guidelines: 1) A building cannot have more than two roofs; 2) No wet insulation can be left in place; 3) The roof structure must be able to handle the additional roof load; 4) The new roof must be attached to the roof deck to meet wind loads (it is not generally acceptable to adhere the new roof to the old roof).
Q: Can I just do the work myself?
Most roofing work should not be a do-it-yourself project. Professional roofing contractors are trained to safely and efficiently repair or replace a roof. Do-it yourself can harm a roof with improper roofing techniques and can harm themselves by falling through a roof even falling off a roof.
Gutters:
1. How often should I clean gutters?
You should clean them at least twice a year. If you have many trees in the area of your home you should clean them 3 to 4 times a year.
Q: What are static vents/ridge vents and do I need ventilation?
We have found that poor ventilation causes roofing material to wear out prematurely. It also ruins the wood deck due to condensation. These two products offer an inexpensive way to greatly improve your roof and attic ventilation.
Q: How about drip edge or ice and snow products?
Drip edge and ice and water shield can be very beneficial in certain unique situations, such as lower pitch, no overhangs, multiple slopes or where pitches come together. These products are probably not necessary in many cases. You may have flashing somewhere on your home. Many of the flashing used in a roof application are included in your price - some are optional. Your proposal will normally show these options if they apply to your job.
Roof Repair
Q: What is the Average Cost and Length of roof repair Project in Houston?
The cost of an asphalt shingle roof repair is in range between $250 to 1000 depending on the type of work to be performed. Most likely roof repair would be higher in Houston due to water or storm damage. If your roof hasn't suffered serious structural damage and is caught before water saturates your sub roofing, your repair project will probably cost less than $500. Roof repair for other types of roofing tend to be more expensive. Metal and slate roofing repairs, for example, are usually around $1,500. At the same time, these roofs (especially metal roofs) rarely need repair. If your current roof has suffered significant damage and is getting old, you might think about taking the money you'd spend on a roof repair and installing a new metal roof.
Shingles:
1. How Do I know if I need a new roof?
You can usually tell with a visual inspection of the shingles. Look for cracks, peeling and any spots where the roof is leaking. If in doubt call a roofer for an inspection.
2. Why does a roof need ventilation?
Ventilation helps remove the heat that builds up during the summer months and helps reduce moisture buildup under your roof. This helps your roof and shingles last longer by preventing the rooting of the wood and curling or distortion of your shingles.
3. How long shingle roof last?
Depending on the system selected, every technology has a good, better and best option with varying degrees of longevity. Your roof will definitely last longer with proper maintenance. Routine maintenance, along with a well designed and properly installed system can as much as double a roof’s life.
From 20 to 40 years
4. What type of warranty should I get on my roof?
Non prorated warranty. You can get best warranties form the certified contractors through extended warranty programs.
New roof installation:
1. How long does it take to have a new roof installed?
That depends greatly on your home and the pitch and design of your roof. Most residential roofs can be redone in two days but it could take as long as a week to complete your re-roof.
Q: What is the price or cost of a new roof?
The price of a new roof varies widely, depending on the material selected, the contractor doing the work, the home itself, area of the country, local labor rates, and more. Keep in mind that cost is only one factor, and it must be balanced against the quality of workmanship and materials. For each roofing material there are different grades-and corresponding prices. Plus, there are a variety of styles and shapes. You need to look at the full product range and make a choice based on your budget and needs. Within the roofing profession there are different levels of expertise and craftsmanship. Pick a contractor who is committed to quality work.
2. How do I select the best roof system for my project?
Based on your location, building codes, weather conditions, and budget you can select roof for your home or commercial building. The roofing contractors like Rocket Roofing Corp will guide you with the roofing materials.
3. What should I do if my roof is leaking?
If your roof is leaking call roofing contractor to inspect your roof and to identify the problem. They will guide based on the problem whether you need to replace or repair roof.
Roof Replacement
Q: When to re roof?
When maintenance and repair can no longer prevent recurrent leakage or extend useful service life, consideration must be given to roof system replacement. When Repair expenditures become excessive, Leakage becomes intolerabe, Damage is occurring to structural components and Damage is occurring to building contents.
Q: What are my options if I decide to re-roof?
You have twoo options when you have decided to re roof your roof.
Re-covering: The addition of a new low slope roof membrane or system or steep-slope roof covering over the top of a major portion of an existing roof assembly.
Replacement: The removal of an existing roof system and installation of a new roof system. This is also known as tear-off and replacement.
Q: What is the best time of year to have my roof replaced?
Roofing materials are safe to install year round, but it should not be a rainy day or week. Check with your roofing contractor and make a schedule to perform work. Usually based on your roof size work might take from 1 day to 1 week.
4. Do I have to replace my roof if it leaks?
Not necessarily, leaks can happen for many of reasons; from easily repairable problems with “flashing conditions” (where a/c units, vents or skylights are located) to more complicated issues of extreme wear. Roofing contractor will come out and assess the situation for you, at no charge. They will tell you exactly what work is necessary. Don’t neglect the leaks take an action as soon as you found the leaks to stop further problems.
5. Should I worry about ice dams?
Ice dams occur when snow or ice on the roof melts and flows to the bottom of the roof. It then refreezes and causes the water behind it to build up. This water then will often find a way into your home underneath shingles and in cracks. This can lead to extensive water damage. You should be concerned about ice dams if you have a roof in a colder climate with a very low pitch or have an older poorly insulated home. If you think you have a problem consult a local roofer for easy solutions.
Tile Roofing
1. If I see broken tiles on my roof, am I going to get a leak during the next rain?
Not normally, the underlayment ("tar paper") provides a secondary barrier to the weather. The broken tiles should be replaced as quickly as possible to keep the rain on top of the tiles and to prevent the sun from cooking the tar out of the underlayment.
Metal Roofing
Q: Why should I choose standing seam metal roofing?
The standing seam metal roof is one of the most exciting breakthroughs in roofing technology in the last 25 years. It fulfills the building owner's need for durable, puncture-resistant protection against the weather while working in concert with the forces of nature. Metal roofing has an established track record in new construction, where it has been used in some 50 percent of all low-rise commercial and industrial buildings erected in the last several years. This acceptance has carried over to the re-roofing market, where standing seam metal roofs have been used successfully as a replacement for built-up and single ply systems. Leading applications for standing seam metal roofs in the retrofit market are schools, factories, warehouses, distribution centers and military facilities.
Q: What are the benefits of metal roofing?
Standing seam metal roofs have many benefits. Metal roofs are:
* Durable. The standing seam roof handles thermal shock through its concealed, sliding clip system. The clip assembly uses a rigid base attached to the building's structural members. An upper part clips the roof panel and forms into a seam during the seaming operation. The clip allows equal amounts of movement in either direction.
* Lightweight. Metal roof panels weigh a relatively modest 1-1/2 pounds per square foot.
* Easy to Install. Metal roofs can be installed year-round. Heavy rain, extremely cold weather or high winds are about the only conditions that prevent metal roof installers from working. In most projects, the metal roof can be installed right over the existing roof, eliminating costly and time-consuming tear-offs. Owners do not need to close the building area being re-roofed if the work must be done while occupants are inside. Occupants can continue their normal activities, even in the immediate area being re-roofed.
* Easy to Maintain. Unlike flat built-up roofs that require frequent maintenance, standing seam metal roofs offer 20 years and beyond of trouble-free performance with little or no maintenance time or expense.
* Weather tight. The standing seam metal roof is designed to withstand rain, wind and snow, and still remain weather tight. Panels are joined together by a weather tight seam that is raised above the roof's drainage plane. Factory-applied organic sealants are applied to the seam during roll forming of the panel. Once on site, automatic field seaming machines complete the seal.
* Metal panels are attached to the roof substructure with concealed clips. These are roll formed or crimped into the panel seams without penetrating the corrosion-resistant steel weathering membrane. The clip system performs two functions: It retains the panels in position without exposed fasteners, and allows the roof to expand and contract during temperature changes.
* Standing seam metal roofs are designed to perform in high-wind conditions and can qualify for a UL 580 wind uplift rating, as well as the ASTM E-1592 wind uplift test. Metal roofs also can carry a Factory Mutual Class A fire rating—the highest in the industry—which can substantially reduce insurance rates.
* Reliable. Standing seam metal roofs assure adequate drainage from rain and snow, effectively solving ponded water problems, leaks and other related troubles commonly associated with flat built-up roofs. In retrofit projects, a sub-framing system is attached to the existing roof surface to provide a minimum 1/4:12 pitch for the new metal roof.
* The panel fastening system is uniquely designed to handle potentially damaging effects from thermal movement. Precisely formed, factory-made metal panels are locked in place by clips inside a raised seam standing two to three inches above the roof surface. The clips have a movable feature that allows panels to expand and contract with temperature changes. The concealed clip system reduces the chances of leaks and makes the standing seam roof attractive.
Q: Are metal roofs energy-efficient?
Yes. Fiberglass blankets are the most common insulation material in standing seam metal re-roofing projects. On some projects, unfaced fiberglass insulation is simply laid directly on the existing roof surface before insulation blankets of the new standing seam roof. For other projects, insulation blankets are installed directly under the metal panels and stretched over supporting members. Foam insulation blocks are often used to separate the panels from the purl-ins to prevent thermal short-circuiting and condensation from forming. The roof expands and contracts independent of the insulation, giving the roof surface a floating action.
Q: Are standing seam metal roofs cost-effective?
Standing steam metal roofs pay for themselves from the day that they are installed. And, they are cost-competitive. Twenty-year material warranties are customary for metal roofing systems, which is considerably longer than the standard protection for built-up and single-ply systems. Long-term warranties are sometimes offered for weathertightness on metal roofs, including those with a 1/4:12 slope. Standing seam roofs can qualify for the UL-90 wind-uplift rating?the highest in the industry?that can substantially reduce insurance rates in high-wind areas. It must be combined with the roof manufacturer's UL-90 system, which includes the panels, concealed clips, sealants and structural supports. The standing seam metal roof can also carry a Factory Mutual Class A fire rating.
Q: Do standing seam metal roofs resist corrosion?
Metal roof panels resist corrosion with the help of a zinc, aluminum, or aluminum-zinc alloy metallic coating applied to the base steel. Additional protection can come from attractive, specially pigmented organic paints that harmonize the roof with conventional brick, concrete and wood sidewall materials. Popular beige and earth-tone colors allow architects to coordinate the roof attractively with other design elements of the building.
Q: I need a material that has flexibility in design. Should I consider standing seam metal roofing?
Yes. Steep slopes and flat roof profiles can be designed with the standing seam roof. The structural roof is the industry's alternative to flat build-up and single-ply systems. The roof spans from support structural to support structural in new construction with slopes of 1/4:12 or more. The architectural standing seam roof is used for visually exposed roofs, mansards facia, and similar applications. It is a water shedder and needs slopes of 3:12 or greater. Like wood shakes, tile and slate, this application needs some form of decking for support and a base felt for added protection against moisture penetration.
Q: Are standing seam metal roofs recyclable?
Yes. The overall recycling rate of steel products in North America is 70.7 percent?the highest of any construction material. Building professionals are becoming increasingly aware of the importance of using recyclable metal roofing materials for retrofit applications over old non-metallic roofs. This helps avoid expensive tear-off and disposal of solvent and chemical-based materials, which often wind up in overburdened landfills.
Q: Should I consider standing seam metal roofing for retrofit projects?
In most retrofit projects, standing seam roofs can be installed right over existing built-up roofs, eliminating costly and time-consuming tear-offs. The metal panels are attached to a steel sub-assembly to provide the necessary slope for ice and water to drain, providing a low-slope solution to flat built-up roofs.
Q: How does the metal roof cost compare to other roofs?
Metal roofs are a premium product and cost somewhat more than a 20 year warranty asphalt/fiberglass shingle roof; however a metal roof can cost substantially less than many of the high-end architectural shingles now being sold. Additionally, metal roofs have many advantages and benefits over asphalt/fiberglass shingle roofs.
Q: Can I walk on a metal roof?
Yes you can; however, like walking on any roof, you should be careful and is not advisable.
Q: Is a metal roof noisy when it rains?
No, metal roofs are not noisy when it rains. According to one study, the noise levels of a metal roof are about the same as other roofing products such as asphalt or wood shingles or clay tiles.
Q: Is a metal roof noisy when it rains?
Metal roofs are very tough and highly resistant to hail damage... much more so than asphalt/fiberglass shingles. In fact, many metal roofing products have the highest impact resistance and hail rating granted by the insurance commissions in the hail belt regions of the U.S. Some insurance companies even provide a reduced rate for metal roofs.
Q: Is a metal roof damaged by hail?
Metal roofs are very tough and highly resistant to hail damage... much more so than asphalt/fiberglass shingles. In fact, many metal roofing products have the highest impact resistance and hail rating granted by the insurance commissions in the hail belt regions of the U.S. Some insurance companies even provide a reduced rate for metal roofs.
Q: How about resistance to wind damage?
All metal roofing products are very wind resistant. Many styles have been tested to withstand hurricane force winds; and wind warranties can be as high as 120mph.
Q: Is a metal roof fire safe?
A steel roof is the most fire safe roof. It is classified as a noncombustible roofing material with a Class "A" rating - the highest rating given.
Q: Does the metal roof color fade?
Metal roofs are painted with high-performance polymers that have exceptional weathering properties. Over time you might notice a slight change in color due to the settling of airborne contamination, but occasional rain or washing the roof with a garden hose (from the ground) will keep the roof looking like new.
Q: What about lightning?
Steel roofing is no more susceptible to lightning than any other roofing material. Lightning most frequently strikes the highest point in any terrain; and if your roof is at the highest point of the surrounding terrain, you can install lightning rods.
Q: If I'm re roofing, do I have to remove the old roof before installing the metal roof?
Usually not if you're installing the metal roof over existing asphalt, fiberglass or composition shingles (maximum of two layers thick). In most situations, the metal roof can be installed directly over the old roof.
Q: Will a metal roof make my house hot?
Actually, a metal roof can save you money on your a/c costs because it has a higher heat reflectivity than other roofing products like asphalt/fiberglass shingles, wood, tile, etc. During the summer it makes buildings cooler by efficiently reflecting away sunlight and reducing the amount of heat transmitted into the building. Likewise, it makes buildings warmer in the winter by reflecting inside heat from the underside of the roof back into the building. This good thermal reflectivity translates into energy savings by reducing cooling costs in the summer and heating costs in the winter.
Q: What is galvalume?
Galvalume is 55% Al-Zn (aluminum - zinc) coated sheet steel that is ideally suited for most types of roofing applications. An estimated 40 billion square feet of galvalume now covers buildings in all kinds of climates and environments throughout the United States, Canada and Mexico, as well as Europe, Asia and Australia. Galvalume is an ideal material for roofing because of its extraordinary outdoor corrosion resistance and resulting long life. It is extremely popular due to its versatility, ease of use, aesthetics and long-term performance.
Why choosing professional commercial roofing contractor is important?
Commercial roofing differs from residential roofing both in materials used and the assembly needed for roof. A commercial roofing contractor deals with a large and detailed draft or mapped plan when beginning roof construction on a tall office building, hotel, restaurant, large apartments or condominium complexes. The main difference between commercial roofs and residential roofs is the size of the roof. Though we use Apartments, Condominiums for residential purpose we still call it as commercial buildings. So generally we classify the buildings into commercial based on their size, height and purpose. For this reason, commercial roof design calls for heavier, sturdier and more robust materials.
Commercial roof construction usually starts with concrete bases being poured (or if pre-poured, carefully laid) to fit with the building structure's top steel beaming and pre-roofing surface. However, commercial buildings roofs are only be handy to building maintenance workers when needed, the final roofing surface is often a moderately wide layer of tarring to prevent any accumulation of water or moisture from damaging the inner roofing. Since commercial roofing construction is completed in larger sections at a time than is most residential roofing, insuring an air and water-tight fixing is crucial to the long-term survival of both roof and building.
Sometimes whole sections of a large office building are replaced, rather than a single small damaged segment with the applied reasoning being that it will be more cost useful to replace the whole segment now rather than wait for further damage and repair each small section as needed. Also, since the larger number of residential structures are decidedly smaller than their commercial opposing partners, and residential roofing (whether tiles, shingles or tar roofing), can easily be repaired or replaced in small segments, whenever there is deterioration or damage, the equipment needed for residential roofing repair is much smaller and less costly that that used in most commercial roofing repair.
The same is true for the work force needed, since often residential roof repairs can be completed by one or two workmen in a short length of time. While one major concern of a commercial roofing supplier, during both commercial roof installation and repair, is assuring the strength and water-tightness of the flat roofing surface, many private residences and apartment buildings have slanted, inclining, or even garret roofing with marginal gutters and drains to eliminate problems from water accumulation. For water, steam and air release, commercial roofing must always work with and maintain clear, unobstructed vents, drains, and submerged (or underlying) piping. These vents are necessary for proper operation of heating, cooling and air circulation systems within commercial buildings while helping to protect underlying and surface roofing materials. Well installed and repaired roofing is uniformly important in both residential and commercial roofing, although very different in nature and maintenance needs.
A residential home will typically only have a chimney jutting out. A commercial building, on the other hand, may have smoke stacks and ventilation systems and pipes, and mechanically wiring, and a roof entrance, and a skylight, etc. All these pose obstacles for the roofer and in some cases so much that a crane has to be called in to aid with the job. Restaurants especially have lots of external machinery on the roof which can cause problems for the contractors doing the roof job.
The products and tools needed for the job can make a difference too. A residential roofer might not have the tools required to handle the bigger scale job of a commercial roof efficiently. They might also not have adequate manpower. There are even new developments in the roofing industry that are bringing about products designed especially for commercial roofing jobs. Products like rubberized roofing materials which are phasing out hot roofing.
The building codes for commercial roofs, warranties are different. It is always advisable to hire a professional roofing contractor who can offer the best warranties from the manufacturers. At the same time it is important to hire the commercial roofing contractor who had been certified in job safety, insured.
So first, you’ll need to find out if your roof is residential or commercial. Most of the time it will be obvious (a house VS a mini mall), but for those that are closer to being both, check with your roofing contractor to find what type of roofing materials serve best for your purpose. Also, make sure that once you know what kind of roofing job yours is, that you hire a roofing company capable of doing that type of job.
Springtime tips for your roofing!!!
Spring is here!! Winter season of snow, wind and ice can brutalize home’s exterior, leaving a number of frustrating roofing repairs in its wake. You know when snow and ice accumulate in gutters and along roof ridges; melting water is unable to drain properly. As water backs up behind these ice dams, it can seep under flashing or penetrate your roof shingles, tiles, ceilings and walls—leading to major water damage. Don't wait until the summer high season! However, for much of the country winter never really arrived. This is the best time to start any renovation that your house or building needs.
This kind of weather can lull building owners and managers into thinking that there is no need for any maintenance, repairs or inspection of their roofs. This year’s unusually warm temperatures still gave way to many bitterly cold nights. These drastic temperature changes can result in unusually rapid and frequent expansion and contraction that add wear and tear to roofing membranes and metal components. When spring rains come, as eventually they will, you don’t want the unpleasant surprise of find out your roof system wasn’t ready for them.
By inspecting your roof you can save many hours of inconveniences caused by leaks. These days roofing companies are offering free inspections. Avoid damage by taking the right decisions on time. The first thing is to inspect the interior of the building to identify any moisture that may be entering the building. This is time where you need a professional roofing contractor who can predict the damage that have done and the solutions that can prevent any damage further.
Winter can do many things to your roof. Make sure that all your gutters; drains and scuppers are cleaned during inspection. A professional should check and tighten drain clamping rings that may have been loosened during freeze-thaw cycles. He can also check collector heads for damage to the joints, and make sure scuppers still have good seals to the membrane.
If your roof has any higher areas over lower roof areas, icicles that fall may cause damage to the membrane below. If you have areas where this type of damage occurs, you may want your contractor to install walkway treatments to protect these areas.
You may also want to install walkways from roof access to roof-top equipment. If walkways are not already there, damage may occur from routine equipment maintenance traffic. Spring is the ideal time to do this, before you need maintenance on your rooftop heating and air conditioning equipment.
Roofs that are coated should be inspected for wear. Weather checking and crazing are also indicators that re-coating should be considered. Give thought to re-coating with a highly reflective coating, to give you added energy savings during the summer cooling season.
Steep roofs are not immune to winter’s ravages. Ice dams can damage shingles, breaking seals, loosen gutters and damage tile. If you have metal roofing in snow country, you need to check for missing snow guards or install new ones where you noticed problems with sliding snow. Also, close attention should be paid to those areas that could be damaged by excessive expansion and contraction that a mild winter can produce. Metal expansion joint covers, elastic expansion joint joints, coping cap joints, pipe flashing or gutter joints should all be checked for damage. Your professional roofing contractor has the experience to know where to look for this type of damage.
Now is the time to contact your roofing professional to get your winter damage taken care of and to perform that needed maintenance that can add years to your roof membrane.
Is green roof a low maintenance roof?
All green roof systems should be accompanied by a detailed written maintenance procedures manual or guideline provided by the green roof installation company or system manufacturer. These should include elements such as irrigation frequency, proper weeding and fertilization, as well as recommended methods for dealing with insect and weed infestations, bare and wet spots, and drainage inspection. Some companies also warrant plant coverage for a designated period of time after installation if the required maintenance is performed. Be sure to review and retain all documentation for a clear understanding on warranty and expectations on roof performance and development prior to installation.
A green roof should receive regular visits similar to traditional roofs. Specific maintenance requirements vary depending the time of installation and type the green roof. However, there are basic fundamentals that should be considered essential during a green roof’s typical two-year establishment period.

Installation Period
During the installation of all green roof components, the following items should be considered top priorities for installation teams and followed up on by facility managers and building owners:
• Ensure all components are being installed as specified.
• Ensure that engineered growing media is at an equal and consistent depth.
• Inspect the placement of all plant material to maximize optimal growth.
• Test and re-test all irrigation systems for proper function. If no irrigation system is currently in place, all plant material should be “watered in.” It is also recommended that a water source be made available on every green roof, regardless of whether a full-time dedicated irrigation system is in place. Simply put, plants need water to thrive, especially in the first few months.
Establishment Period
After installation is complete, a maintenance contract should be instituted between the facility manager or building owner and the maintenance contractor or, more ideally, the installation contractor. In addition to this contract, the following items will also need to be accomplished and repeated during the first 90 days:
• Conduct full a walk-through, with all parties present, before the project is deemed complete. Determine proper installation, and ensure that the contractor addresses any installation issues immediately with installing contractors before departing from job site.
Like all roofs, garden roofs need maintenance and inspection to ensure their longevity.
• Remove and properly dispose of any excess materials or debris from the roof surface.
• Inspect all surface drains and scuppers to ensure each component is also clear of any debris. This element should become habit and second nature to anyone visiting the roof at any time.
• Dependent on various seasonal and regional aspects, the irrigation system may need to be winterized and/or calibrated on an annual basis. Each spring, all zones should be turned on and tested for proper function. It is common that plant material requires a greater amount of water the first 90 days than any other period to get the plants established. If no irrigation system is present, hand watering may be required to ensure that plants successfully move their roots into the growth media.
• Designate a plant manager or plant inspector who is responsible for continually monitoring the media levels, plant material and growth to ensure that any problems are quickly identified and resolved.
Growth Period
The first year is vital to the survival of any green roof installation. If the roof survives this stage, it likely has a great shot at meeting all establishment and warranty goals.
• Inspect all media and roof components for erosion issues and proper irrigation. Any issues should be delivered to the green roof manufacturer immediately. (Note: While some manufacturers are willing to assist their clients well into the “growth” stage of the green roof, others may not be so helpful.)
• In the spring after the first year of growth, a spring clean up is recommended to aid the growth of new plants. All plant material that still has dead flowers or stalks must be deadheaded. All vegetation-free zones (drains, skylights, perimeters) should also be cleared of weeds or encroachment of desirable green roof plants. Any sedum material removed can be used as “cuttings” in the bare areas within the green roof.
• Any plant material that may have perished during the first winter should be replaced at this time. Some manufacturers offer warranties that include free plant replacement.
• Growing media that has eroded due to wind or water should also be replaced. It is critical that a comparable media is used for any replacements. Improper material can result in filter clogging due to high clay content or compaction, which is undesirable to plant roots.
• A final walk-through at the end of green roof warranty period should be conducted. Some green roof companies offer a final walk-through before the warranty expires.
Long Term
These steps are not always necessary but might be crucial to a project’s long-term success:
• As-needed monitoring and testing of the growing media. Some companies have soil experts on staff to give long-term support long after installation.
• Although costly, consider fertilization applications to meet the requirements of certain plants based on their performance. It is advisable that a plant’s fertilization needs are outlined during the design phase of any green roof project. No fertilizers should ever be used without the consent of a qualified green roof professional.
• On a rare occasion, pesticide applications might be required at this stage if there are any issues with insects on your green roof. Utilize an integrated pest management program (IPM), and consult a qualified professional.
• While mechanical weeding is always the most environmental and economical approach, herbicide applications are another possibility of green roof maintenance at this stage. Be sure to consult the local municipality or original design team for permission of use.
Replacing Flat roofs with Metal roofs !!!
Re roofing flat roofs with sloped metal roofs is a new concept that is delivered by the experienced construction experts in these economic times. Interestingly 75 percent of all roofing work is replacement and repair. Industry sources said that annually 40 billion square feet of roofing is installed in United States and they also suggest that 30 billion square feet of roofs needed major repairs in 2009.
By adding slope to an existing flat roof, you can lower your energy costs and little or not maintenance overhead. Mostly, a new roof can be installed without having to remove the existing flat roof. A slope as low as one-quarter inch per foot is sufficient to satisfy most metal roof warranties and can be achieved by installing light-guage steel columns in varying lengths. After the columns are installed , steel purlins are positioned between each of the columns and the necessary bracing is installed. A new metal standing seam roof panel system is then placed on top of this sub framing system.
If properly maintained the exterior surface should last at least 30 to 50 years. Adding fiberglass insulation in the newly created cavity can further increase the building's ability to conserve the energy used to control temperatures in the interior spaces. The cost of installing new metal roof over flat roof is less than the cost of replacement options.
Adding a structural metal roof to an existing building is a smart decision because the system will last for decades. It is also an environmentally responsible choice since metal roofs are manufactured from recycled materials and the system itself is considered almost 100 percent recyclable. Moreover, a metal roofing system allows the use of additional insulation of solar panels that reduce reliance on electric energy.

Metal Roof Flashing
Metal Roofing Flashing:
Metal roofing flashing is necessary for a variety of reasons. The purpose of roof flashing is to provide a way for water to run off the roof into the gutter system, without being trapped under the roof tiles, causing it to become damaged and ineffective. Metal roofing flashing is used at roof joints where the roof connects to the house. It should be installed when a house is built or the roof is replaced in order to protect the home from leaks, rot or complete damage to the roof. The material used and type of installation will determine the effectiveness of the roof flashing system.
Metal Roofing Flashing advantages:
- Protects the home from Moisture and Leaks.
- Adds to the roof’s duration.
- Low to no-maintenance requirements.
