What You Should Know About Flat Roof Blistering

Flat Roof blistering occurs when the roof loses its adhesion, creating raised areas that can be filled up with air or water. These blisters typically look like a bubble on the roof’s surface, and they can grow larger as they allow more moisture in.

When left ignored, roof blisters can cause bigger problems that require more extensive repairs. In some cases, the condition may result in a commercial or residential roof replacement.

In this article, Sully Jones Roofing shares some tips on how you can prevent and treat roof blisters.

Preventing Flat Roof Blistering

In order to prevent roof blisters, you need to:

  • ensure proper installation of the materials;

  • keep the materials dry; and

  • inspect the roof regularly.

When installing commercial roofing, it’s crucial to ensure that the materials and weather condition are dry. In the event of bad weather, your roofer will have to wait for the right weather and for the roof to completely dry out. Furthermore, they have to observe the correct installation process so as to ensure a firm contact between the materials and the adhesion works properly. Afterward, it’s important to conduct regular roof maintenance in order to prevent major damage to your substrate or building.

Fixing Roof Blisters

For eroded bare spots on small blisters, these can be coated with a cold-process asphalt coating and sprinkled with gravel. And if the dimension of a blister has grown into two feet, you should have this area marked and checked periodically to see if it’s getting any larger. If the blister approaches approximately five feet or occurs in a high-traffic area, it should be repaired immediately.
