The Top Causes of Blistering on the Roof of Your Sugar Hill Property

Does your roof have a noticeable bubble bulging up from underneath the materials? This issue, known as blistering, is a major issue that can significantly reduce your roof's lifespan. What exactly causes the bubbling?

Learn what causes blistering on roofs from the experts at Adams & Sons Roofing. They specialize in roof repair in Sugar Hill, GA, and will correct any blistering that occurs on your roof. 

Improper Ventilation

Think of how important it is to ventilate your home when you create steam in your shower or kitchen. These areas of the house can retain moisture from the steam and potentially damage your walls or furniture. Your roof also needs adequate ventilation to prevent blistering. 

The ideal roofing system will release heat and trapped moisture from the attic. This protects the shingles from both thermal shock and overheating, both of which contribute to blistering on roofs.

A study from the U.S. Department of Energy reports that homes with vented attics are less likely to experience roof leaks. You can save yourself money on repair costs by making sure that your Sugar Hill home and roofing system has the proper ventilation in place.  

Damaged Shingles

Many homes in Sugar Hill, GA, use asphalt shingles because they are durable, cost-effective, and look great on any style house. However, your roof will turn into an eyesore if it has defective shingles that blister. Here are two common ways that your shingles cause blistering:

  • Trapped Moisture: Any amount of moisture that seeps into the layers of your shingles will cause the materials to expand with heat. The blister should go away once all the water evaporates, though low-quality shingles won't be able to withstand the problem. 
  • De-Granulation: The small granules that cover the asphalt layer of the shingle are key for protecting the roof. If these granules start to fall off the shingle, wind, moisture, and UV rays will take their toll on the roof and lead to damage. 

Poor Installation

Sometimes, your roof will blister due to improper installation. Roofers may not build your structure according to code and fail to include an underlayment. As a result, your roof may have noticeable ridges beneath the shingles that compromise its durability and lifespan. 

It's crucial for roofing crews to install the roof in dry weather only. Any traces of moisture that get inside a felt underlayment during installation will cause wrinkling. You can request that your roofing contractor use a fiberglass-reinforced underlayment to avoid this issue and prevent blistering.
