An Introduction to Rubber Roofing

When it comes to choosing the right roof for your building, the options seem endless. One option to consider is EPDM rubber roofing, which provides a cost-effective, durable solution to your roofing needs.

What Is EPDM?

EPDM rubber roofing EPDM (ethylene propylene diene monomer) is a flexible rubber membrane that is most often used on commercial buildings with flat or low-slope roofs. A black EPDM roof can help melt ice and snow and keep the building warm in colder weather. Black is also the most common and least expensive color option. However, white EPDM is available through the addition of titanium dioxide and can help reflect heat and keep buildings cooler.

How Is EPDM Installed?

An EPDM roof can be installed in a variety of ways: mechanically fastened, fully adhered or ballasted. Mechanical fastening is the most common method, whereby the rubber membrane is attached by fasteners that are screwed into the roof deck. A fully adhered roof involves applying a specific type of glue to the entire EPDM membrane to secure it to the roof deck. Finally, the ballasted method involves using an adhesive around the edges of the membrane and securing with a heavy ballast, often stone or sheetrock. Aluminum bars may also be used to help secure the membrane and prevent sagging, shrinking or damage to the membrane.

What Are the Benefits?

Among the primary benefits of an EPDM roof are its low installation cost, longevity and minimal repair costs. EPDM lasts as long as traditional shingle or sheet metal roofs and is easy to install. It is also a very durable, weather-resistant roofing option. It withstands a wide range of temperatures, is wind-resistant, UV-resistant and watertight. EPDM was originally used to line ponds and canals, so it has a proven history of algae and mold resistance.

If your building needs a new roof, consider EPDM for an affordable, long-lasting option.
