Asphalt shingle blistering is one of the most common issues many homeowners face. When this happens, you better watch out – it is usually an indication of a serious problem that must be addressed promptly.
What Are Asphalt Shingle Blisters?
Loss of adhesion in asphalt shingles leads to the creation of pockets or bubbles on the roof surface. They may pop over time, leaving pockmarks characterized by eroded granules and exposed base matting. This makes it easy for rain, wind and other elements to hasten the roof’s deterioration. Patching up the pockmarks where the blisters once was won’t cut it, which is why roofers have to replace the affected shingles with new ones.
What Causes Asphalt Shingle Blisters?
There are two reasons as to why blistering occurs in asphalt shingles – trapped moisture and poor roof ventilation. Here’s what you need to know about each:
- Trapped moisture: Blistering happens when moisture is trapped in your shingles during the manufacturing process. As the sun heats up the shingles, the moisture will start to heat as well, causing the outer shingle layer to rise and develop blisters.
- Poor roof ventilation: Adequate ventilation is vital for the longevity and weather performance of your roofing system. Without it, shingle blistering may occur as a result of trapped attic heat baking the shingles from underneath.
How Do You Prevent Shingles From Blistering?
Minimizing asphalt shingle blistering starts when you keep these things in mind:
- Invest in high-quality shingles. The risk of blistering is reduced when you choose asphalt shingles manufactured by leading industry brands like GAF.
- Have your shingles installed by the pros. The best way to prevent blisters is to have your high-quality shingles installed by trusted and reliable professionals. They make sure the new shingles are stored in an environment where it won’t attract moisture. During installation, they’ll also see to it that the system has enough vents so it can facilitate air circulation within the attic and ensure the roof’s structural integrity.
