Blistering roof shingles threaten the security of your home. Blisters can lead to leaks, and leaks can lead to problems.
You likely have a long to-do list when it comes to home improvement projects, but understand that shingle blistering is not only a cosmetic defect — it could seriously shorten your roof’s life.
Why Do Shingles Blister?
One of the main reasons a shingle blisters is because it’s exposed to high temperatures for an extended period of time. If your home is not situated in the shade, direct sunlight can lead to extreme heat damage.
This problem also can crop up when moisture is trapped underneath shingles. This might happen if shingle adhesive is not installed correctly. Water makes the roofing materials expand, but when it evaporates, it leaves behind a small blister.
Additionally, when there isn’t enough attic ventilation or insulation, it leads to a change in temperature between the roof’s surface and the attic’s interior, promoting conditions that contribute to the development of blisters.
Can You Prevent This Issue?
You can lower your chances of your roof suffering blistered shingles by making sure your contractor avoids cheap materials. If your roof is up for replacement, don’t cut corners on shingles. Only use the best available product to protect your home, such as GAF shingles.
In addition, you should make selecting a high-quality roofing contractor a priority. A dependable professional can make sure your attic has enough ventilation, whereas a no-name company only may be concerned with completing the job as quickly as possible.
Finally, make sure you trim away all overhanging tree branches. Sometimes blistering roof shingles aren’t an issue until they pop. If you have a constant stream of debris falling onto the roof, the impact could pop the blisters, initiating moisture damage and further shingle degradation.
Here’s What You Should Do
If you notice you have areas of blistering on your roof, it’s wise to have a professional take a look up close. Since blisters usually appear about a year after the roof is installed, assessing the extent of the blistering should be the first task your contractor undertakes.
A small amount of minor blistering will most likely not lead to leaks, but you might want to repair the damage anyway to keep your roof’s aesthetic appeal.
