– Classic Metal Roofing offers residential metal roofing that looks like wood shakes, slate or tile. Made from aluminum, Classic Metal Roofing contains 98% recycled content. It is extremely energy efficient, recognized by the EPA Energy Star program as a cool roof. It is lightweight, typically installed over existing shingles without a tear-off, saving tremendous waste from landfills. And it is a permanent roofing system, made to last a lifetime rather than be replaced every 15-20 years.
