Roofing Care Basics: What Can Cause Roof Blisters?

Asphalt shingles are one of the most popular roofing options available. That being said, they are not without their downsides. Today, our roofing and drywall repair experts talk about a common asphalt roofing issue: roof blisters.

What Are Roof Blisters?

Roof blisters show up as unsightly bumps on the surface of the roof’s shingles. In some cases, blisters manifest as groups of small bumps, while in other cases they appear as large bumps. Large roof blisters will usually be missing the top part, exposing a hollow area that can trap water and speed up the deterioration of the shingle.

Moisture

Excessive moisture is partially responsible for the formation of blisters. Water that gets trapped between small seams in the shingle’s top layer tends to expand after the temperature rises, pushing the surface up and forming the infamous bumps. Getting high-quality shingles from a reputable roofing and drywall contractor will help decrease the likelihood of blistering.

Poor Ventilation

The moisture alone isn’t enough to cause blisters to form. Gaps that the water can seep into are caused by something else: poor ventilation. With poor ventilation, different temperatures from the top and bottom of the shingle cause it to expand and contract unevenly, pulling the shingle layers apart.

Blisters as a Warning

Blisters can be treated as a warning that the shingles are too old or weak, making them vulnerable to more serious problems. This means it’s the perfect time to get new shingles for your roof.
