3 Common Causes of Membrane Roof Failure

A membrane roof, sometimes called a flat roof, is used as a watertight covering to protect the interior of a building against elements such as heat and rain. It is commonly made from thermoplastic, modified bitumen or synthetic rubber. When installed correctly, the materials of a membrane roof are either seamless or have a proper seal at all seams.

In this article, a flat roof roof replacements specialist shares some of the most common causes of seam failure in membrane roofs and what you can do to prevent it.

Why Do Membrane Roofs Fail?

1. Weathering: All roofing materials have an expected life span, and exposure to severe weather conditions can speed up the process of their deterioration. Powerful winds, ultraviolet rays from the sun and torrential downpours can all have a long-term impact on your membrane roof, causing it to shrink and become brittle. Once the seams are compromised, it is only a matter of time before you will need a roof replacement.

2. Improper Insulation: Incorrect placement of insulation or errors in its installation can also lead to seam failure. When the installer fails to follow the correct installation procedures, the insulation beneath the membrane could distort and form fractures across the surface of the roof. Professional roof inspections allow you to discover and address this issue.

3. Poor Installation: Poor roof installation is known as the most prevalent cause of seam failure in flat roofing systems. If the seams are not properly sealed, for example, there would be gaps where moisture can seep in, affecting other components of the roof. This could lead to mold growth, electrical hazards, decay and water damage.

The Takeaway

The importance of correct installation cannot be overemphasized. Make sure you choose a qualified and reputable roofing professional to install your roofing system and inspect it regularly so you can get the most out of your investment.
