The answer to 'why is my roof curling shingles' is that curling shingles are a common roofing issue caused by a variety of factors, including improper installation, age, and environmental conditions. Curling shingles can lead to leaks, water damage, and other problems if not addressed.
Some common causes of curling shingles include poor ventilation in the attic, exposure to excessive heat or UV radiation, and improper nailing or placement of the shingles during installation. Over time, the shingles can become brittle and start to curl at the edges or in the middle. This can allow water to seep in and cause damage to the roof and the interior of the home.
