What Causes Asphalt Shingles to Curl?

Shingle curling can make your roof look like an ugly mess, but you shouldn’t shrug it off as a simple cosmetic issue. If neglected for a long time, it can have an impact on the performance of your roof and result in more extensive damage.

Causes of Asphalt Shingles Curling

In this article, McGuire Roofing & Construction, one of the most trusted residential and commercial roofing contractors in the area, discusses how curling occurs in asphalt shingles.Causes of Curling

Curling usually occurs because of wear and the only solution to this is replacing your old roof. But if your roof is relatively new and have started developing curling patterns, you may have to dig deeper to find the root cause.

According to roofing contractors, curling can be a sign of roof vent issues or moisture problems. Other times, shoddy installation causes asphalt shingles to curl. No matter what you’re dealing with, hire a reputable and experienced contractor to get your roofing fixed.Curling and Other Wear Patterns

It’s easy to spot curling and other wear patterns, but it can be a challenge to distinguish one specific pattern to another. Identifying it correctly matters because it helps determine the cause and appropriate solution. Getting it wrong can result in repair mistakes.

Take note of the following characteristics of different wear patterns:

  1. Curling – occurs only at individual shingle tab corners
  2. Cupping – shingle perimeters are lifted with the center having a concave shape
  3. Fishmouthing – an upward curve in the center of a shingle tab

Always consult with a professional to be sure of the roofing issue. Have your roof inspected and fixed as soon as you notice any damage.
