Why are my shingles curling?

Curling shingles are a common sight on roofs, and are a warning sign for underlying problems. The first place to check if your shingles are curling is your attic. Lack of sufficient ventilation tends to be the cause of most shingle damage. If your attic is not ventilated properly, then it can become very hot and this will cause damage to your roof.

Moisture builds up if the attic isn’t properly ventilated, which causes mold to grow. Not only will mold damage your home, but it can also be hazardous to your health. If you determine that the attic is the problem, it is vital to add a ventilation system to your attic before it does any more damage to your roof.

Depending on the age of your roof, shingles that are curling at the sides could also simply indicate that it’s time to replace your roof. Depending on the type of shingle material used and who installed it, you may need to replace or repair your roof once every 25 years or more.

If your roof is relatively new and you have ruled out attic ventilation problems, then your roof may not have been properly installed. If the contractor didn’t know what they were doing or did a sloppy job, then the shingles might be poorly aligned or nailed improperly. If this is the case, it is best to bring in an outside opinion to assess the roof. You may need to hire a new contractor to fix the job of the last contractor.

When dealing with damage to your roof, it is important to check if your roof is under warranty, since it can be a big expense to repair a roof (but even more expensive to redo a larger portion of your home that has been negatively impacted by a damaged roof.) If your roof is still under warranty, then be sure to speak with the contractor as soon as possible. If you wait too long, whatever is causing the shingles to curl could cause irreversible harm to your home.

If you find out that you need to replace your roof, make sure to get a warranty with your new roof so that you do not have to spend more money out of pocket if a similar issue arises again. A warranty is always recommended, even on repairs.

Since it can be difficult to inspect your home’s roof on your own, and you might not know what to look for, the best action to take is to call your local roofing contractor to assess the situation. Many will offer a free estimate on what it will take to repair or replace your roof.

It is important to quickly find the source of the curling shingles before any more damage is done to your home.
