EPDM Roof - LargeEPDM (Ethlyene Propylene Diene Monomer) is an elastomeric polymer synthesized from ethylene, propylene and a small amount of diene monomer, compounded with carbon black, processing oils and various cross-linking and stabilizing agents. As a thermoset membrane that recaptures its shape after stretching, EPDM roofing maintains its physical properties for decades. It has the ability to withstand extremes of temperature and expands and contracts with the building. EPDM is manufactured in large sheets varying in width from 10 feet to 50 feet, and features lengths up to 200 feet. The membrane can be reinforced and comes in thicknesses of 45, 60, 75 and 90 mils.

The greatest test of any roofing material is how it performs under actual field conditions. Forty years of empirical experience in field applications has shown EPDM to have the roofing industry’s longest average serviceable life.

The advantages of EPDM include:

  • Minimal maintenance and an effective lifespan of 30 years or more
  • Cyclical membrane fatigue resistance
  • Proven hail resistance
  • High resistance to ozone, weathering and abrasion
  • Flexibility in low temperatures
  • Superior resistance to extreme heat and fire
  • Thermal shock durability
  • Ultraviolet (UV) radiation resistance
  • Wind damage resistance

EPDM Roof - BlackEPDM’s high resistance to wind damage has also proven to be an increasingly desirable attribute. EPDM membrane roofing systems can be designed to meet a variety of wind uplift criteria.

EPDM Repair & Restoration
One of the unique attributes of EPDM is the ease in which it can be repaired and restored””an attribute not common amongst all roofing systems. Even after years of exposure to “mother nature”, repairs or modifications can be accomplished easily, with the expectation of long-term performance.

EPDM roof repair can be as easy as washing the membrane, preparing the surface and applying the repair material, including coatings.

In terms of aging or damaged roof systems, EPDM can now be restored to original installation quality without major costs or disruption to business. In some situations, when system enhancements are incorporated, the aged roof system is restored to a condition that exceeds that of the original installation.
