As a locally trusted residential roof replacement contractor in the area, we know how important it is to have a sturdy roof to protect homes. With regular maintenance, its longevity can be extended, and money can be saved in the long run. But sometimes, there are some roofing issues that happen unexpectedly, such as blisters on shingles. You may probably notice that some of your roof’s shingles have blisters. Dealing with this is not complicated to do, but let’s have a look first on what can cause shingles to blister.
The Common Causes
Blistered asphalt shingles are not an uncommon occurrence. This happens when moisture gets trapped in the shingles during the manufacturing process and is heated up by sunlight. The moisture evaporates and causes blisters to form on the shingles. Even if this is happening to your home’s roof, it’s not as bad as it looks so long as the asphalt granules are still intact. In this case, the blistering won’t affect your roof’s longevity.
However, it’s a different story if the blisters start to pop. When this happens, the granules on the shingles become dislodged and leave the asphalt shingles unprotected from the ultraviolet (UV) rays of the sun. The blistered area of the roof will slowly lose more granules over time and its ability to protect the roof from the natural weather elements. Eventually, the shingles will lose their effectiveness and can lead to water leaks, internal roofing damage and a costly roof repair.
Fixing and Preventing Asphalt Blistered Roofs
To make sure the blistered shingles don’t pop, be careful not to walk over them. They can easily pop when they’re under foot traffic. Falling debris, such as acorns, pine cones and small branches from nearby trees, can pop the blistered shingles so make sure they’re cleared from the roof. But then even these precautions won’t prevent natural causes to pop the blistered shingles, such as hailstorms. If this is the case, then it may be wise to have the shingles replaced instead.
