3 Reasons Why Your Roof Shingles Are Curling

By Cass Jacoby, RCS Reporter.  

Curling roof shingles don’t always signal that it is time for a roof replacement, here are a few different causes of curling shingles. 

No one wants to see roof damage on their home. When you see the curled shingles, it is easy to fall down a rabbit hole of researching and trying to find money in your budget to get a new roof. However, curled shingles don’t always mean that it is time to replace your roof. Here are three reasons your roof shingles may be curling.  

1 – Aging or defective shingles  

This Old House notes that, as asphalt shingles age, their corners often begin to curl downward or upward. If you catch your shingles curling early on enough, simply gluing down the shingle beginning to curl works well enough as a fix. Some shingles curl just because they are defective. 

2 – Poor ventilation 

A curled shingle can indicate lots of moisture build up in your roof that can be contributed to poor ventilation. If you have a poorly ventilated attic in your home, you my start to see your roof shingles curl. This is a huge sign of a much larger problem; moisture build up in poorly ventilated roofs can lead to mold growth.  

3 – Incorrect roof installation 

Shingles may also curl if they are mis-aligned or nailed down improperly. If you have a recently installed roof and find your shingles curling, it is most likely because the shingles weren’t installed the right way. 

As soon as you identify curling shingles contact your local roofing professional to diagnose the curling so you can prevent curling shingles from turning into a much larger problem. A roofing professional will help provide you with the best solutions to the cause of your curling shingles.
