1. Moisture Accumulation
It occurs when water or moisture becomes trapped between layers of roofing material, causing bubbles or blisters to form on the surface. One of the leading causes of moisture accumulation is poor ventilation in the attic or roof space. You can resolve it by installing proper ventilation systems to allow the excess moisture to escape.
Another cause is aging or damaged blistering shingles, which you can fix by replacing the damaged shingles. Regularly inspecting and repairing any leaks or damage to the blistering roof can prevent moisture buildup.
Proper ventilation can prevent moisture buildup while fixing leaks, and ensuring adequate installation can also prevent blistering. Installing a vapor barrier between the layers of the roof can help prevent moisture from penetrating and causing further damage.
2. Hail Storm
When large chunks of ice, known as hailstones, pelt a roof with force, it can create air pockets under the shingles or roofing material. These air pockets can expand and cause the roof’s surface to bubble or blister.
It can weaken the roof’s structural integrity and potentially lead to leaks. You can carefully cut out the blistered spots and fill them with roofing cement.
Most homeowners’ insurance policies cover damage from hail storms, and filing a claim can help cover the costs of repairs. More on hail roof damages you can find online to fix your roof as soon as possible.
3. Excessive Heat and UV Exposure
These environmental factors cause the roofing material to expand and contract, leading to bubbles or blisters on the surface. These blisters can compromise the roof’s integrity and make it more susceptible to water damage.
The first step is to identify and repair any potential leaks. Next, you can carefully cut and flatten the blisters with any trapped air or water drained out.
Address the root cause by reducing the amount of heat damage and UV rays exposed to the roof. You can achieve this by using reflective or heat-resistant roofing materials and regularly maintaining the top to prevent damage.
You can also add a layer of roofing cement that you can then apply to seal the blister. Alternatively, a roof coating can protect the surface from further UV damage.
