EPDM is a single-ply rubber membrane that has been used on roofs in the USA since the 1960's. It is relatively inexpensive, simple, and clean to install. There aren't the odors and fumes that accompany built-up roofs which appeals to many property owners and managers. EPDM roofing is designed to exhibit superior flexibility, high strength, and outstanding weathering in practically all climates. The three standard applications for EPDM are fully adhered, mechanically attached, and loose-laid.
