It’s hard to miss the signs when asphalt shingles curl. The appearance of your roof changes and more importantly, curling affects the performance of your entire roofing system. Moss Roofing, a top-rated provider of residential roofing services, shares more information on why asphalt shingles curl.
Shingle curling is usually apparent on the corners of a shingle tab. This normally happens on old roofs due to wear. In this case, the only way to deal with it is to replace the roofing. However, if your roof is relatively new, curling may be considered a red flag for some other roofing issue.
Typically, it’s an indication of a roof vent issue or a moisture problem. Sometimes this can also be due to shoddy installation. But whatever has caused your asphalt shingles to curl, you should call a professional roofer immediately. Have your roofing inspected so that the right solution can be introduced.
How to Determine Shingle Curling Patterns
There are varying patterns of deformities that can be found on asphalt shingles. Oftentimes the terms referring to these patterns are used interchangeably. However, they have differences that should be noted.
For instance, “cupping” is when shingle perimeters appear lifted while the center has a concave or “cupped” shape. Meanwhile, “curling” occurs at individual shingle tab corners and “fishmouthing” has an upward curve in the center of a shingle tab. These patterns are the result of varying conditions, so it’s important to call them by their correct names. Otherwise, you may end up treating the wrong problem.
Of course, it’s not really easy to see the differences especially if you have an untrained eye. That’s why you should call a professional to inspect your roof and confirm the issue.
