What Blistering Shingles Mean And How To Fix Them

Shingles are a popular roofing option for many homeowners. Not only are they affordable, but they also come in a variety of colors and styles to match any home. However, one of the biggest concerns with shingles is when they become blistered. Blistered shingles can be an eyesore and a sign of underlying problems. If your shingles are blistering, learn how you can fix them.

What Is a Blistered Shingle?

Blistering occurs when air or moisture gets trapped between the shingle layers. As a result, bubbles or blisters will form on the surface of the shingle. These blisters can be small or become large and visible, and they often look like raised bumps on the shingle.

What Causes Blistering?

There are several factors that can lead to blistering in asphalt shingles. One common cause is poor ventilation, which can trap heat and moisture in the attic, leading to blister formation. Additionally, excessive heat from direct sunlight can contribute to the problem. Furthermore, manufacturing defects in the shingles themselves can also play a role. It is important to address these factors to prevent or minimize the occurrence of blistering in asphalt shingles.

How to Correct Blistering?

The good news is that blistering shingles can be fixed. The first step is to identify the cause of the blistering. This will help determine if the problem is minor or if a replacement is necessary. A roofing professional can inspect your roof and assess the extent of damage.

In some cases, the blistering can be corrected without replacing the shingles. The roofer can simply cut and glue the blisters down or apply an asphalt patch over the holes. On the other hand, if the problem is due to poor ventilation or excessive heat, it may be necessary to install proper ventilation or a new roof altogether.

How to Prevent Blistering?

Prevention is always better than a cure. To prevent blistering, ensure that your attic is well-ventilated and that any leaks are repaired promptly. It's also crucial to choose high-quality shingles that have been tested for reliable performance. Lastly, make sure you hire a qualified and experienced roofing contractor for installation.

Blistered shingles can be a warning sign of underlying roofing problems. While they can be corrected, it's essential to address the underlying cause to ensure a long-lasting solution. The good news is that with proper diagnosis and restoration, your roof can be restored to its optimal condition.
