Rubber ethylene propylene diene monomer (EPDM), torch down and modified bitumen are some of the most popular roof membrane options. They have seams that can be adhered with glue, asphalt, tape, heat welder and other materials. If your installer fails to join these seams together, your roof is more likely to suffer damage or deteriorate early. Besides poor installation, there are more reasons some membrane roofs fail at the seams. 

Membrane Roofs

Improper Roof Installation

You must carefully choose the contractor you will hire for your project. When someone inexperienced installs the roof membrane and fails to seal the seams correctly, leaks will eventually occur. Even though membrane seams overlap, it does not guarantee that they are well-sealed.

Normal Wear and Tear

Every day, your roof is exposed to harsh outdoor elements, such as rain, ultraviolet (UV) rays and high winds. Over time, normal wear and tear will cause your roof to become brittle and shrink. All roofing materials naturally deteriorate as they age. If your membrane roof is old, it’s more likely to fail at the seams. 

Poor Insulation Installation

Another common reason the seams of membrane roofs fail is improper insulation installation. Insulating your roof helps your interior stay warm in winter and cool in summer. When not secured to the roof, the membrane will deteriorate faster and humps will form beneath the material. These humps will then pull on the seams, resulting in tears in several areas of the roofing system.
