What is EPDM?

Ethylene propylene diene monomer, better known as EPDM is a versatile rubber roofing membrane that has been used in the low-slope commercial roofing industry for over half century.

EPDM offers a variety of installation options and numerous long-term benefits, such as:

  • superior weatherability
  • exceptional wind uplift resistance
  • extreme flexibility

EPDM is virtually immune to ozone, UV radiation, and harsh temperatures. With the presence of carbon black fillers within the membrane, UV radiation is absorbed and converted into heat, to which the membrane resists very well. EPDM does not rely on plasticizers for its flexibility, so there is no danger of the material becoming brittle from plasticizer loss throughout the life of the roof.

Rapid and Easy Installation – EPDM is available in large panels (30.5m x 5.8m) that can be installed using primers and self-adhesive products, no flames or electricity is required.Low Life Cycle Costs – With little or no maintenance required throughout the life of an EPDM roof, and a competitive installation cost, EPDM roofing systems result in a very low life cycle cost.

High Flexibility and Elongation in any Climate – EPDM elongates over 300% to accommodate building movements in climates worldwide. EPDM has proven performance in Canadian winters at -45 °C and in tropical Madagascar climates at +45 °C.

Sustainable and Environmentally Friendly – EPDM is an inert material with limited environmental impact during manufacturing, installation and use. EPDM is also fully recyclable.
