What is EPDM..??

EPDM has gained industry-wide acceptance and respect by providing immediate and long-term roofing solutions. As more emphasis is placed on the sustainable performance of building materials, EPDM continues to be the roofing material that stands the test of time.

With durability, flexibility and ease of installation, EPDM is a versatile roofing solution you can count on. From residential or office buildings and distribution warehouses to hospitals and schools, EPDM delivers outstanding, long-lasting performance no matter the climate. 


Benefits & Characteristics of EPDM
  • EPDM is a synthetic rubber roofing membrane that is commonly installed on residential and commercial roofs. Its two primary ingredients, ethylene and propylene, are derived from oil and natural gas.
  • Superior cold weather performance. EPDM can be installed in temperatures as low as 20 degrees
  • Exceptional Wind Uplift Resistance
  • EPDM can be installed either fully adhered, mechanically attached or ballasted, with the seams of the roofing system sealed with liquid adhesives or specially formulated tape.
  • Installed as thin sheet materials 0.030 (30 mils) to 0.090 inches (90 mils) thick and are applied to the roof in a single layer.
  • EPDM rubber membrane sizes can reach 50′ wide by 200′ long. These huge pieces are great for avoiding possible leaks at the seams, but these wide rolls are also very difficult to handle during the installation.
  • EPDM rubber membrane may require a layer of insulation installed in between the roof deck and the membrane to improve energy performance. This is especially important, as EPDM membranes are commonly dark in color and will attract a significant amount of solar radiant heat.
  • Excellent Commercial Use Application: EPDM has no pungent odor, so it’s perfect for installation on buildings that help make life happen..such as hospitals, schools, and manufacturing facilities that need to remain open and occupied during the roofing process.
  • Limited Color Options – typically black or white.
  • Expected Life-Span: 20-30 years

Installation of a Resilient Roof

With any roofing material, the proper application of the membrane is as important to the satisfactory performance of the roofing system as the materials themselves. Meticulous application processes are especially important if a roofing system is resilient when threatened by extreme weather events.

The first and most basic decision to be made before application begins is, “How will the roofing membrane be secured to the layers that support it?” Here, for instance, there are three options for EPDM: mechanically attached, adhered, and ballasted. Mechanically fastened roofs secure the membrane to the roof with fasteners and plates, which vary depending on the roof deck material. In any adhered roofing system, the membrane is bonded to the layer below with adhesive. Ballasted roofing systems rely on the weight of aggregate – usually stones or pavers, or a combination of both – to hold the membrane in place and resist uplift.
