Top Reasons Why Your Roof Shingles Are Blistering in the Michigan Heat

If you've noticed the hot weather is affecting your home's roofing shingles, you aren't alone. Having your shingles blister during high temperatures can be quite common in Michigan. 

As experienced roofers, we have seen numerous instances of roof shingles blistering and have helped properties recover. This article will cover why your roof shingles may blister during the Michigan summer heat.

What is Shingles Blistering?

When shingles blister, there is moisture or air trapped inside pockets within the shingles that expand due to the rising temperatures. This situation often happens due to direct sunlight, causing a bubble or blistering appearance.

If left unfixed, these blisters eventually pop and leave your roofing system susceptible to damage. Spotting the blisters on your asphalt shingles is critical for maintaining performance. 

Michigan's Summer Heat

Michigan is generally not thought of as a state with warm weather, but the summer sun can cause heat damage to a property's structures. As the shingles absorb heat throughout the day, they can expose defects in the roof's design.

Additionally, the high humidity sets up the perfect environment for pockets of moisture to develop within the shingles. As a Michigan homeowner, you should remain aware of the dangers that high temperatures pose to your property's roof. 

Why Do Asphalt Shingles Blister During the Summer

There are a few things that can increase the chances that your home's shingles will blister during the summer. In Michigan, the shingle blistering is more likely to appear in July due to:

  • Poor Attic Ventilation 
  • Manufacturing Defects
  • Improper Installation
  • Direct Sun Exposure

How Blistering Can Grow into Bigger Issues

Along with your asphalt shingles developing blisters, the issues can continue if you don't repair the damaged shingles. Blistered shingles are more than a cosmetic issue and can significantly shorten the lifespan of the roof.

Once a shingle blister has popped, it can leave the underlying structures susceptible to UV and water damage. Over time, this can lead to weakened roofing structures and leaks.
