Curling shingles are one indication that your roof is in bad shape. If you’ve noticed cupping (upward turning of shingles) or clawing (downward curling at the edges), it is likely that your roof system is aging and is in need of repairs.

Ignoring the problem can only make things worse, as the curling can become extensive and allow water to enter your home. If you notice curling shingles in your roof, you may probably be wondering how it happened in the first place.

Roofing contractors in Worcester, MA, share what causes your shingles to curl:

Improper installation

When roofers didn’t follow the strict requirement for installation, early problems like curling is likely. This can happen if they didn’t use the right number of nails allowed per shingles, or the use the wrong length and type of nail.

Improper placement of nails can also cause issues. This can cause curling or loose shingles over time.

Multiple layering

There are cases where it is okay to put a second layer of shingles on a top of an old one. This might be a cheaper option, but when the existing roof itself is not good condition, this is not a good idea.

If the existing roof, for instance, has already curling shingles, installing a new roof over will cause problems, which may include curling again.

Poor ventilation

As hot and moisture-filled air goes into the attic, proper ventilation is important. This prevents heat buildup that may cause the shingles to fade and weaken. If your attic is poorly ventilated, the moisture from the air is likely to get trapped and cause other problems like mold and curling of shingles.

Old age and roofing materials

Regardless of how good the roofing materials are, shingles can curl toward the end of their lifespan. You should also know the extreme weather temperatures can take a toll on your shingles and accelerate aging, especially in an already old roof. It is best to repair or replace it sooner to avoid bigger problems down the road.
