Given the extreme weather conditions and other possible elements that may damage your house, it’s still likely for your roof shingles to weaken despite regular maintenance. This is worth noting especially for areas where hailstorms are frequent. This means getting a roof replacement will be even more inevitable as blistering and swelling are expected to occur. To understand the reasons behind this dilemma, we’ll talk you through it. 

Standard asphalt shingles are known to have two layers— the backing material and the outer granule layer. The manufacturing process involves feeding large rolls of uncut sheets of backing material onto rollers and soaking them in hot asphalt. These sheets can be made from pulp made of paper and fabric or flexible fiberglass.A layer of granules is sandwiched on one side of the still-wet sheets. These protect the outer layer of the asphalt shingles from UV damage while providing the roofing color and other features like resistance to algae. After cooling, the shingles are then cut to size, laminated with another layer if required, and packed for shipping.As mentioned, the common causes of roof blisters include moisture, insufficient ventilation, and faulty installation. Blisters can form on an extremely hot roof surface making poorly ventilated roofs prone to this particular dilemma. Once these are ignored, they can become bigger, letting more moisture penetrate the membrane, leading to costly roof repair and replacement. Hence, the best way to avoid and address this problem is to ensure your roof is installed properly.
