EPDM is a synthetic rubber roofing material. Durable in nature, it is made from Ethylene Propylene Diene Terpolymer. This material can be applied to the roof surface multiple ways; Fully adhered, mechanically fastened, or ballasted (built-up). EPDM comes in a variety of widths, which can be beneficial. The process of applying larger sections to the roof surface can create fewer seams and therefore have fewer points for adhesion to fail. Like modified bitumen, if leaks do occur, small sections of membrane can be laid out and applied to cover the necessary section. Therefore, repairs are cost-effective, fast, and easy.
One incredible benefit to EPDM roofing material is its fire resistance. It is extremely difficult to ignite. This durability has been known to impede the progress of fires. It also lasts a long time. While most warranties last 30 years, some EPDM roofs have been known to last 50 years or more. The newer rubber formulas are even creating membranes that are even more durable and more impervious to radiation and damage from UV rays.
EPDM is highly wind resistant when fully adhered and stands up well to hail. Flexible in nature, this roofing membrane is pliable and settles into the roof structure. It is also highly resistant to extreme hot or cold weather.
This material, however, can be prone to tears, and if not professionally installed, can commonly develop small leaks around vent pipes and other roof protrusions. This can be avoided by ensuring your EPDM roof is installed by an experienced professional. When choosing any roofing material it is important to consult a contractor with plenty of experience, in knowledge with the project they are completing. A true professional will help you determine the best solution for all your roofing needs.
