What Is EPDM Roofing


In a nutshell, EPDM roofing is a rubber roofing material that is widely used throughout many countries for low-sloping roofs. It has a long technical name, but the most important elements are ethylene and propylene. These are naturally-occurring petroleum-based substances that go into making different types of synthetic rubber. EPDM is used since it is flexible, easily applied, and waterproof, making it the best material for a low-slope roof.

Low-Slope Roofs

A low-slope roof is, as the name suggests, a roof that has little slope to it. That would be in contrast to the roofs you might see on a house that come to a sharp angle. A low-slope roof is most commonly found on business buildings and apartment complexes.

One of the major problems associated with these flat roofs is the propensity for them to collect water. Since they have little or no slope, they can collect water after it rains, and the water will sit there for a long time. That adds excess weight to the roof, invites mould and mildew, and serves as a breeding ground for pests. Also, it can eventually start to seep into the building. Roofers in Huddersfield can install EPDM roofing to prevent such problems.

Waterproof Roofing

EPDM is a waterproof material that is applied in sheets and taped or glued down with another waterproof material. Such materials means that it will not absorb water, which is very important. If a roofing material absorbs water, it will expand and contract due to moisture. It will also eventually start leaking into your building. EPDM does not do that, so you can keep your building protected.

EPDM also does not readily interact with many different substances that might degrade or destroy other roofing materials. It is chemical and tear-resistant. That’s why so many businesses choose to use it as their primary roofing material.
