Our roofing system is constantly exposed to the elements, which is why even the most durable roofing systems are bound to run into problems later on. One of the most common issues, especially for flat roofs, is roof blistering. In this post, the top roof inspection and repair company, Evans Roofing and Gutters Inc., shares the causes of flat roof blistering, and how it can be prevented or repaired.
What Are Roof Blisters?
Roof blisters can be found as circular spots or crater-like formations on your roofing system’s surface. Blisters can also be spotted in painted roofs, shingles, and most especially in flat roofs. Roof blisters form when excessive moisture gets between the roof’s top layer and the substrate. Once the water evaporates, it leaves a raised, brittle bump that will eventually pop, causing a blister.
How to Treat Roof Blisters?
Roof blisters can be repaired depending on the type of roofing system. A coated roof can be repaired by scraping off the damaged part and reapplying a fresh coat. For membrane roofs, your roof repair expert will cut off and patch the affected parts. The same can also be said for flat roofs. Make sure that your roof repair projects are handled by a skilled contractor to ensure that your roofing system is back in great condition.
How to Avoid Roof Blisters?
Generally, roof blisters can be avoided if there is enough ventilation in your attic. Having too much heat and moisture in your attic will force the air to escape up the roof, forming blisters that will eventually pop, leaving their characteristic crater-like damage. Make sure that your attic is well-ventilated and that your seams are sealed properly to ensure proper moisture levels.
