As reported by the Cool Metal Roofing Coalition and the Oak Ridge National Laboratory, installation of reflective metal roofing can save your home up to 40% in summer cooling energy costs while highly emissive metal roofs can reduce urban air temperatures by as much as 12 ° F.

For homes in warmer climates, pre-painted or granular coated metal roofing systems not only reflect solar energy but also cool your home by re-emitting most of what solar radiation is absorbed.

14. Is a metal roof environmentally responsible?

Not only is DML USA Metal Roof great for your home, it's great for the environment. The recycled content of the steel in a metal roof is about 95% from production to installation to reuse far superior to asphalt.

According to the National Association of Homebuilders Research Center, 20 billion pounds of asphalt shingles are dumped into U.S. landfills every year. If you loaded those shingles into tractor trailers, then lined them up end-to-end, they would make a line from New York City to Los Angeles, back to New York City again, then on to Chicago. That's a lot of wasted asphalt. But because a metal roof can often be installed over your current roof, without tearing off what's already there, metal roofing helps to reduce this excessive shingle waste.
