5 Signs of Asphalt Shingle Deterioration

According to information from the Asphalt Roofing Manufacturers’ Association, asphalt roofing is a popular choice for residential customers. Recent research shows that 80% of homes use this sort of roofing material, and with billions of feet produced per year, asphalt shingles cover millions of homes annually. Although these shingles are known for durability, they might suffer from certain issues with time. Below are the most common asphalt shingle issues seen by roofing contractors.


A blister is an elevated section of a shingle that may be caused by various factors. While small blisters are considered to be part of the normal aging process, blisters on new shingles may indicate a manufacturing defect or poor roof ventilation.

Curling and Cupping

In most instances, curling is a humidity-related issue. Moisture can get into the shingles during manufacturing, or it may accumulate due to inadequate ventilation. When the moisture escapes, the shingles may shrink. Depending on the nature of the issue, the shingles can be sealed with hot glue or, in severe cases, the roof may need to be replaced.

Raising and Lifting

Poor installation may leave the shingles unable to withstand wind damage and uplift. As shingles must have a sufficient number of fasteners in the correct positions, it’s important to choose a certified, licensed contractor for roof installation or repair. Uncertified roofers may not install shingles correctly, which will void the manufacturer’s warranty.

Tearing and Splitting

Tearing commonly occurs when temperature shifts cause shingles to split or crack, compromising the roof’s integrity. When left untreated, these splits and cracks let dampness in through the shingles into the roof’s other layers.

Granule Loss

Similar to cracking and splitting, granule loss typically indicates the end of the shingles’ life. However, there are times when it occurs earlier. If this applies early in the life of the roof, the shingles are deteriorating prematurely, and customers should call a local contractor for advice.
