Cupping, Curling, and Clawing Shingles

Cupping, Curling, and Clawing Shingles

 Cupping, Curling, or Clawing shingles on your roof are a sign that something is wrong. Cupping is when the center of the shingle is concave or depressed, so the tile forms a cup. Curling or Clawing is when the edges turn up or down, even if the center is flat. Some causes include:

Normal Wear and Age

Cupping, Curling, or Clawing can be a normal and expected sign that your roof life is coming to an end.

Extreme Weather

If your roof is not particularly old, but you see Cupping, Curling, or Clawing in your shingles, it may be because of harsh weather such as: hail, changes of extremes in temperature, and/or moisture.

Poor Roof Ventilation

Proper ventilation can increase the life of your roof. Make sure to have proper airflow and ventilation in your attic. Failure to do so can cause premature Cupping, Curling, or Clawing of your shingles.

Installed by a Pro

Make sure your shingle installation was done by a GAF Master Elite Certified, Owens Corning Platinum Preferred, or CertainTeed Pro roofing company!
