The answer to 'roof installation curling' is that roof shingles or tiles can start to curl or buckle due to a few common causes. This typically happens when the shingles are not installed properly, or when they are exposed to extreme weather conditions over time.
Some of the main causes of roof installation curling include poor ventilation in the attic, moisture buildup, and improper nailing or adhesive application during the installation process. Over time, the shingles can become brittle and start to curl up at the edges, which can lead to leaks and other roofing issues. In many cases, curling shingles will need to be repaired or replaced by a professional roofing contractor to ensure the integrity and performance of the roof.
