Asphalt shingle roofs are durable. They can protect your home against extreme weather conditions, but various factors can cause the shingles to blister. Here are three reasons why shingle blistering occurs and ways you can prevent it, according to residential roofing experts.
Common Causes of Asphalt Shingle Blisters
Manufacturing Issues
During manufacturing, moisture can get inside the asphalt shingles. And once the shingles are installed and exposed to the sun’s heat, these pockets of moisture will appear, looking like blisters. At this point, shingle blisters pose no threat to your roof. They’re merely cosmetic issues. However, when the blisters pop, this leaves your roof exposed to the elements.
Insufficient Roof and Attic Ventilation
Good ventilation ensures your attic and roof remain at consistent temperatures. Without proper ventilation, your shingles will become excessively hot, causing the blisters to show up and potentially pop.
Preventing Asphalt Shingles From Blistering
Roof Maintenance
Regular maintenance by a reliable residential and commercial roofing company ensures your roof will be in good shape. Regular inspections will also reveal your roof’s current condition and help you spot issues that require immediate repairs. Without regular maintenance and inspection, you won’t be able to detect the blisters and prevent them from causing harm to your roof.
Attic Ventilation
Good attic ventilation reduces the chance of blisters growing and popping, thus extending the lifespan of your roof. It also reduces mold growth and improves indoor air quality. Roofing contractors are equipped with the knowledge of designing an efficient attic ventilation system. Get in touch with them so that you can figure out how to improve your home attic ventilation.
