When asphalt shingles blister, the appeal and performance of your roof is compromised. The unsightly blemishes caused by blistering doesn’t only drag down your curb appeal; they also create weak spots on your roof where leaks can easily form. To protect your asphalt roofing system, it’s crucial to first learn why it happens in the first place.
- Inadequate ventilation – Poor ventilation causes asphalt shingles to blister and deteriorate over time. When the interior heat continues circulating around the attic, your roof suffers, particularly your shingles that have to constantly adjust to the changing temperatures inside and outside the roof. When this happens, a premature roof replacement may be the answer. In case you do seek a replacement, it’s a good idea to discuss installing enough vents with your roofing contractor to ensure proper ventilation.
- Trapped moisture – Moisture can get trapped under asphalt shingles, especially after a powerful storm. The water will eventually evaporate when exposed to direct sunlight, causing the materials to expand and form small blisters. Be sure to always schedule an inspection to catch issues while they’re still minor and manageable.
- Product defects – While it’s unusual for asphalt shingles to blister due to manufacturing defects, this isn’t entirely impossible. This may happen if you purchase substandard materials or hire a shady contractor to do the work. To ensure the best performance for your roofing system, always look for high-quality shingles manufactured by trusted names like GAF, and then have a professional like Pritchett Bros do the work.
