Why Do Asphalt Shingles Curl?

Asphalt shingles are the go-to roofing choice for many homeowners–and with good reason! They offer great weather protection, allow for many design possibilities and are highly energy-efficient. However, they’re not invincible, and one common problem that might affect your asphalt shingles is curling. Gresham Roofing and Construction, the premier emergency roof service provider in the area, discusses what causes this problem below.

Insufficient Attic Ventilation

When heat and moisture accumulate inside the attic, the roof can “bake” from underneath, causing the sealing strips of the asphalt shingles above to curl. The best way to prevent this is to ensure your attic is properly ventilated. Proper attic ventilation not only keeps your shingles intact, it also reduces the risk of mold and rot.

Defective Roofing Material

Another reason asphalt shingles curl is due to manufacturing defects. This can cause poor adhesion of the bituminous coating and grit. Alternatively, a low-quality substrate may have been used. To avoid these problems, you should always work with a certified roof replacement company that offers top-of-the-line products from the leading brands. As a certified GAF, Owens Corning and Versico roofing company, we can ensure the asphalt shingles we install have passed strict quality specifications, allowing for superior and long-lasting performance.

Poor Roof Installation

Asphalt shingles may curl upwards during high winds because their sealing strip isn’t securing the material, as per the manufacturer’s specifications. Maybe the shingles weren’t nailed properly. If you notice excessive curling in your asphalt shingles, contact a trustworthy roofing contractor like Gresham Roofing and Construction for an inspection. We’ll determine if the roof can still be repaired or will require a more permanent solution.
