MRA recently participated in the Green Build International Conference and Expo, demonstrating the eco-benefits of metal roofing (see photo).
Tests conducted by the independent Oak Ridge National Laboratories (ORNL) indicate that a cool metal roof can save a homeowner up to 25% in cooling costs compared to a dark-gray asphalt shingle.
ORNL’s field tests have shown that the combination of venting and increased reflectance can reduce the heat penetrating the roof deck by about 45 percent for stone-coated metal roofs compared to an asphalt shingle roof in certain climates. Ongoing research with standing-seam cool-colored metal roofs is showing similar results.
