Roofing Materials

A building's roof system and its finished roofing materials shield a structure's interior from natural elements. Roofing systems generally fall into two general categories: 1) high-sloped or "pitched" roofs (residential) and 2) low-sloped or flat roofs (commercial). These two types of systems generally are constructed differently and use different materials, although some materials are used for both residential and commercial systems. EPA's designation specifically covers roofing materials containing steel, aluminum, fiber, rubber, plastic or plastic composites, and cement.
