Why Some Membrane Roofs Fail at the Seams

Membrane roofing systems on commercial properties are available in several different materials, each of which require different installation methods. No matter your choice, some of them have one common denominator - the seams. These are deemed the weakest parts of a membrane roof and are more likely to fail. Today, we discuss the causes behind seam failure in membrane roofs and tips to prevent it from happening.

Common Causes Behind Seam Failure Modified bitumen, rubber ethylene propylene diene monomer (EPDM) and thermoplastic membrane roofs are some of the commercial roofing systems that are more at risk of seam failure. Excessive wear and tear is usually associated with this roofing issue. After all, membrane roofs are exposed to the weather every year, causing shrinkage and brittleness. Poor insulation is also another reason why seam failure occurs in membrane roofing systems. Incorrect installation causes the material to warp, with some of the sections forming humps as a result of air pockets forming underneath. If not addressed properly, tears may start to appear at the seams and other parts of the roof surface, necessitating a roof replacement. Preventing Seam Failure Incorrect membrane roof installation is the leading cause of seam failure. Experienced installers should be able to fuse the seams using the appropriate method, making sure there are no voids and wrinkles, and the entire material looks flat all over. To ensure you get the most out of your membrane roof and prevent its seams from failing early, you need to work with a reliable roofing contractor like A1 Quality Roofing, Inc.
