Asphalt shingles, a popular roofing material, occasionally exhibit a phenomenon known as “blisters.” While advancements in manufacturing have reduced their occurrence, they can still pose challenges for homeowners and roofing professionals alike. In this guide, we delve into the causes, implications, and solutions for asphalt shingle blisters.
Understanding the Formation of Shingle Blisters
At the core of an asphalt shingle are two primary layers: the backing material and the protective outer granule layer. The production process involves:
- Introducing large rolls of backing material, which can be organic (comprising paper and fabric) or composition (flexible fiberglass), onto rollers.
- Immersing these sheets in molten asphalt.
- Pressing a layer of granules onto one side of these still-wet sheets. These granules shield the asphalt shingles from ultraviolet (UV) damage, impart color, and offer additional features like algae resistance.
- After cooling, the shingles undergo cutting, possible lamination, and packaging.
However, if humidity within the manufacturing facility isn’t adequately controlled, moisture can become trapped between the asphalt and granule layers. This trapped moisture might not evaporate even post-installation. When exposed to prolonged sunlight, this moisture expands, leading to the formation of blisters.
The Implications of Blisters on Asphalt Shingles
If blisters form on asphalt shingles post-installation, the most effective remedy is to replace the affected shingles. Typically, blisters appear within the initial years of the roof’s lifespan. Hence, the issue should fall within the warranty period, negating the need for a complete roof replacement. However, homeowners should be aware that while the warranty might cover the shingles, labor costs, including tear-off and disposal, might not be included.
Furthermore, it’s crucial to differentiate between blisters and hail damage, as they can appear similar when viewed from ground level. While insurance usually covers hail damage, it doesn’t cover blisters. Inaccurate assessments by inexperienced insurance inspectors can lead to denied hail damage claims, mistaking them for blisters. Therefore, it’s advisable to have a professional roofing contractor, like BLC Roofing, conduct the inspection to ensure accurate damage reporting.
