A common problem with asphalt shingles is blistering shingles. There are two main reasons for blistering asphalt shingles, which often call for home roof repairs.
Moisture can sometimes get trapped within the shingle itself during the manufacturing process. If moisture has been trapped by the shingles on a roof, they are very likely to start blistering. Why? Because the trapped moisture also heats up as the sun heats up the shingles and can cause blisters to rise on the shingle.
For shingles, roofs that do not have an adequate ventilation system can get too hot. If a poorly ventilated roof gets too hot because of the intense heat, the shingles may blister.
Are shingles that blister bad? Yes and no. As long as the blisters on the shingles keep their granules, the roof won’t have a problem, and there is no need for a roof replacement. There will come a time, however, like all blisters when they will surely pop. The granules dislodge when blisters pop on shingle roofs, leaving the asphalt unprotected from the sun’s ulraviolet (UV) rays.
What Happens When Blisters Pop?
When this happens, the roof area is prone to losing more and more granules. These popped blister areas can actually lead to leaks and roof damage. Here are some tips to help prevent them from popping.
Be careful not to walk on shingles that are blistered. Blistered shingles may pop up when the foot traffic disturbs them. There are also some homes surrounded by trees. If you have trees that keep dropping pine cones, acorns, limbs or other types of debris onto your roof, blisters might pop. Removing these trees may be of great benefit so you can avoid costly repairs.
Another prevention method is to replace the shingles of asphalt before they pop. However, this could be an expensive repair based on how many blistered shingles. Prevention, as they say, is always better than cure.
