Why do my shingles curl and what does it mean?

Cedar is a very attractive roofing material, which is one of the reasons why people are willing to spend a little more money to install cedar shingles on their roof. Cedar is available in rich and warm colors that can enhance the beauty and curb appeal of your home. However, cedar does require care and maintenance to look good. One of the most common problems it can develop is curling.

What is Curling?

Curling, also known as cupping, is when the shingles curl, change shape, or become distorted. Usually, the shingles are flat and clean looking, especially when they’re first installed. Most homeowners want to maintain this clean look but cedar shingles will curl a little over time. This gives your home and roof a distinct character and identity. However, if the curling and cupping is excessive, you need to call a professional immediately.

Why Do the Cedar Shingles Curl?

These shingles are made from natural hardwood material and will flex according to the weather conditions. Constant exposure to intense sunlight and heat during the day and cold temperatures during the night and winter months can cause the wood to expand and contract. The shingles are also exposed to moisture on a regular basis, especially if you live in a wet climate region. A combination of all these natural forces can cause your cedar shingles to curl and warp.

What Should You Do if Your Cedar Shingles Curl?

Slight curling in a few shingles is natural and will only add character to your roof. However, excessive curling in several shingles is an indication that you need professional assistance or that you need to replace the shingles on your roof. You should also keep a look out for other signs of damage like cracking, splitting, and fraying. If you see excessive damage, your shingles need to be replaced because they will no longer provide the protection your home requires.

Don’t attempt to replace the shingles yourself, even if you might save some money if you do. If you’re not careful, you might damage the roof structure and that can lead to expensive repairs. A professional will replace the shingles carefully without damaging the underlying roof structure.
