The answer to 'roof curling' is that it is a common roofing problem where the shingles or tiles on a roof start to curl or buckle upwards. This can be caused by a variety of factors, including age, improper installation, exposure to the elements, and poor ventilation in the attic.
Some key symptoms of roof curling include shingles or tiles that are no longer lying flat, gaps between the shingles, and visible wear or deterioration. If left unchecked, roof curling can lead to leaks, water damage, and even structural issues with the roof itself. In many cases, roof curling is a sign that the roof is nearing the end of its lifespan and may need to be replaced.
