There’s an array of roofing issues that contractors deal with when attending to flat roof repair requests. Among the most common ones are blow-offs, ponding water, roof leaks and moisture. Although not as often discussed, roof blistering is another persistent problem that flat and low-sloped roofs encounter. But why do asphalt shingle roofs blister, and how can this be prevented or fixed? In this post, we’ll focus on unraveling the situation to help you avoid costly repairs and potential roof failure.
Trapped moisture in asphalt shingles. One of the main reasons behind asphalt shingles blistering is a poorly-executed manufacturing process. There are times when moisture gets confined within the shingle itself. After constant exposure to the sun, this trapped moisture starts to heat up, creating blisters on the surface of your roof. This is why you need to hire an expert contractor who only offers products from the leading manufacturers in the industry, one of them being DECRA® roofing.
Poorly-ventilated roof or attic. Your roofing system or attic can get extremely hot if it doesn’t have adequate ventilation in place. This situation causes areas on your roof to bubble up, causing unsightly blisters to appear. Make sure to regularly inspect your roof and monitor small blisters in case they suddenly pop, causing granules on shingles to dislodge. When this happens, your roof will be left unprotected from damaging UV rays.
Unsatisfactory workmanship by installers. Faulty installation also plays a factor in roof blistering. If roofing materials weren’t relaxed or installed when the outdoor temperature was right, this could result in wrinkles, leaks or blisters. These issues increase the likelihood of structural damage and reduce your roof’s life expectancy. Be sure that the roof repair contractor you’ve hired is thoroughly trained and has superior installation skills.
