What Is EPDM Roofing?

EPDM Roofing

EPDM

EPDM (ethylene propylene diene terpolymer) is a synthetic rubber roofing membrane that has been around for nearly 40 years. EPDM is a black rubber roofing system that is very similar to tire tube membrane, however it is much thicker and typically reinforced with polyester to enhance its durability and resistance to cracks and punctures. EPDM consists of two primary ingredients including ethylene and propellent which are derived from oil and natural gas. It can either be installed fully adhered, mechanically attached or ballasted, and its seams are sealed with a liquid adhesive or tape.

 

Benefits of EPDM

Warm-Roof-Construction-EPDMEnvironmental Responsiveness- 

EPDM is one of roofings most sustainable and environmental materials used today. It has low life cycle costs as well as low impact on our environment. The production of EPDM has a low energy number and several components were created for use with the membrane to reduce VOC (volatile organic compounds) emissions during installation of the roofing system. EPDM is also one of the worlds most recyclable low-slope roofing products which in turn minimizes the impact on landfills, and overall our environment.

Economic Value- 

Not only does EPDM have a low cost per square foot, when used in white its surface has a high emissivity which allows energy to be reflected back into the atmosphere rather than absorbed into the building. Therefore the building can “cool” off quicker therefore reducing heat and energy costs.

Overall System Benefits-

  •  Cyclical membrane fatigue resistance
  • Hail resistance
  • Resistance to ozone, weathering and abrasion
  • Low temperature flexibility
  • Thermal shock durability
  • UV radiation resistance

Ballasted EPDM is a roofing system whose components are held into place by river-washed stones or pavers. They are loose laid, which means that their insulation as well as the roofing membrane are not fastened to each other or to the roof deck. The sheets of EPDM are spliced together, and both the membrane and insulation are held down by a minimum of 10lbs of ballast per square foot. This roofing system has been popular choice because it has low life cycle costs, and quick and economical insulation .
