fire resistant slate roof « »


The Duesenberg of roof coverings, slate is elegant, timeless, and nearly indestructible. As a noncombustible, it receives a Class A fire rating. Suppliers, such as Evergreen, sell slate designated S1, the American Society for Testing and Materials’s highest grade, rated to last 75 years. Since slate weighs 700 to 3,000 pounds per square (the number of tiles it takes to cover 100 square feet), depending on thickness, make sure your home's roof structure can support it before you buy. $700 and up per square, installed.
