EPDM (Ethylene Propylene Diene Monomer) synthetic, rubber roof membranes have been used on roofs in the United States since 1960 and 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

  • Installs easily with large sheets which reduces a tremendousamount of labor as compared to other roofing systems
  • Lightweight; great for use as a recovery system
  • Because no aggregate surfacing is necessary, maintenance and repairs are easily accomplished
  • Available in .045 mil, .060 mil, and .090 mil to meet every need
  • Traffic Resistant
  • Fast track system for time sensitive projects

EPDM System Design Considerations

  • Roof must have positive drainage
  • Roof should not be expected to be used as a traffic surface
  • Buildings venting any type of contaminate onto the roof surface should incorporate grease traps or recovery systems
