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.
