Lightweight and Green
Metal roofs also have a few other great things going for them. Compared to an asphalt roof, metal roof panels are typically about 50 percent lighter. They also may have a recycled component. While it varies by manufacturer, the recycled component can be as high as 30 percent or more. When the time comes to retire a metal roof, the metal can be recycled again and again. The rates of recycling for asphalt roofs are sadly far below that of metal.
