The answer to 'asphalt shingles curling' is that curling shingles are a common roofing problem caused by a variety of factors, including improper installation, age, and weather exposure. Curling shingles can lead to leaks, water damage, and decreased energy efficiency in the home.
Some of the most common causes of asphalt shingle curling include: poor ventilation in the attic, exposure to UV rays, and improper installation techniques. Over time, the shingles can become brittle and start to curl up at the edges or in the center. This can allow water to seep under the shingles and cause damage to the underlying roof structure.
