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.

Recommended Recovered Materials Content Ranges:
EPA's Recovered Materials Advisory Notice (RMAN) recommends recycled-content levels for purchasing roofing materials as shown in the table below.
| Material | Postconsumer Content (%) | Total Recovered Materials Content (%) |
|---|---|---|
| Steel 1 |
16
67 |
25-30
100 |
| Aluminum | 20-95 | 20-95 |
| Fiber (felt) for Fiber Composite | 50-100 | 50-100 |
| Rubber | 12-100 | 100 |
| Plastic or Plastic/Rubber Composite | 100 | 100 |
| Wood/Plastic Composite | -- | 100 |
| Cement | Refer to the cement and concrete specifications. | |
šThe recommended recovered materials content levels for steel in this table reflect the fact that the designated item can be made from steel manufactured in either a Basic Oxygen Furnace (BOF) or an Electric Arc Furnace (EAF). Steel from the BOF process contains 25% - 30% total recovered steel, of which, 16% is postconsumer steel. Steel from the EAF process contains a total of 100% recovered steel, of which, 67% is postconsumer steel.
Product Specifications:
EPA recommends that procuring agencies refer to the 186 standards for roofing products maintained by ASTM's Committee D08 on Roofing, Waterproofing, and Bituminous Materials.
