Asphalt shingle blistering is a common issue many homeowners face. It’s more than just a cosmetic concern — it can also be a sign of potential roof damage. Discover what causes it to happen and ways to prevent it in this blog post from top roofing experts Easton Roofing.
Asphalt shingle blistering refers to the tiny bubbles or raised areas that form on the surface of your shingles. This is often due to trapped moisture or air that expands when heated by the sun. Over time, these blisters can open and expose the underlying material, shortening the lifespan of your roof.
The following are some of the common reasons behind the formation of blisters in asphalt shingles:
Poor Roof Ventilation. The right amount of intake and exhaust vents helps regulate the temperature and moisture levels in your attic. Inadequate ventilation, be it due to incorrect vent size or presence of obstructions, prevents air from circulating in and out of the attic, affecting the shingles and other roof components.
Manufacturing Defects. If the asphalt mix in the shingles contains too much moisture or air, the material may expand when exposed to heat, causing blisters.
Improper Installation. If the shingles aren’t properly attached to the roof deck, air might get trapped underneath and cause blisters to form.
Neglecting blistering shingles can have significant consequences. When blisters open, they can leave your roof vulnerable to other forms of damage, such as granule loss, leaks, or worse, roof failure. This can result in costly repairs down the road.
Professional roofing contractors can assess the extent of the damage and work with you on the best solution to prevent shingle blistering from shortening the lifespan of your roof. They will ensure your roof has adequate ventilation and that insulation and other materials don’t block the ventilation channels.
