Roof shingles are a popular roofing option because they’re affordable, easy to install, and offer excellent durability. But over time, they sustain damage from weathering, aging, and constant exposure to harsh elements. Here’s more about these problems and how to identify them so that you can prevent the damage from worsening.

What Are the Types of Shingle Damage?

1. Curling

Shingles have to be nailed down to keep the roof secure. However, strong winds can cause roof shingles to lift and curl at the edges.

Curling can also happen with inadequate ventilation—the excess moisture and heat trapped in the roof decking cause the shingles to wear out faster due to higher temperatures. Consult a contractor about applying a roofing sealant underneath curled edges to reattach them to the surface. The professional can also replace them if necessary.

2. Cupping

Cupping occurs when roof shingles appear to have a raised middle. Sometimes, the wear pattern looks like a wave at the center, and it’s an indication of impending failure.

Poor roofing ventilation can cause premature wear, so address this for prevention. If cupping occurs, you may need to replace the damaged shingles to maintain the roof’s integrity.

3. Blistering

Roof shingles can have blisters, which are random erosions or pockmarks on the surface. These are formed when volatile gases expand and get released from the asphalt layer, breaking the topmost part of newly installed shingles.

Apart from adequate ventilation, proper installation also prevents blistering. With severe blisters, the underlying mat is fully exposed, shortening the longevity of the shingles.

4. Flaking

Asphalt shingles have granules on the surface that serve as protection against UV rays. They shed these grains over time—flaking is common for older roofs, and it’s a sign that the roof shingles are nearing the end of their life span. The only way to deal with this type of damage is to replace the roof as soon as possible.

5. Bruising

Hail can leave deep indentations on the surface that reach the matting. This type of damage is common in hailstorm-riddled areas and compromises the shingles’ capacity to shed water efficiently. Water can pool inside the holes, so it’s better to replace these shingles right away.
