EPDM Roofing Membrane

EPDM (Ethylene Propylene Diene Terpolymer) synthetic, rubber roof membranes have been used on roofs in the United States since 1960. It is one of the most common types of low-slope roofing materials. This is because it is relatively inexpensive, simple to install, and fairly clean to work with when compared to conventional built-up roofs. There are fewer odors and fumes that accompany built-up roofs which appeals to many property owners and managers. The properties of EPDM - resilience; tensile strength; elongation; resistance to ozone, ultraviolet light and ponding water make this membrane an excellent roofing material.

Advantages of EPDM Roofs
