What Causes Flat Roof Blisters?

Have you ever noticed those peculiar, bubble-like formations on your flat roof? Roof blisters are akin to bubbles forming under your roof’s membrane or coating. They form when air or moisture gets trapped, leading to sections of the roof swelling or blistering. If left unaddressed, they can wreak havoc on the integrity of your roof. 

What Causes Flat Roof Blisters?

In this article, commercial and residential roofing expert US Roofing explores what causes blisters on your flat roof and why it’s so important to have a professional roofer repair it.

Causes of Flat Roofs Blisters

There are many reasons why a flat roof can develop blisters, including the following:

  • Excessive heat and direct sunlight can cause the roof’s temperature to rise. Eventually, this can lead to the expansion of trapped air or moisture, thus forming blisters.
  • Improper installation may also lead to blistering. For instance, if the roof membrane doesn’t adhere correctly, it can create pockets where air or moisture can gather.
  • Seasonal changes can also have a significant impact on your flat roof. Moisture getting trapped under the flat roof membrane is more likely during winter snowfall and spring rains. Without proper maintenance, it can cause the material to blister, especially when temperatures rise. 

The Importance of Proper Installation and Routine Maintenance

Fixing roof blisters is never a DIY endeavor, as it requires specific understanding of singly-ply roofing materials and installation techniques to correctly repair them. Thus, it’s best to hire professional commercial roofing contractors who can accurately identify the cause of the blisters and use the right methods to fix them to prevent further damage.
