The answer to 'roof curling' is that roof curling is a common problem where the edges or corners of roof shingles start to lift or curl upwards. This can be caused by a variety of factors, including age, sun exposure, improper installation, or damage.
Symptoms of roof curling include visible curling or lifting of the shingle edges, cracking or splitting of the shingles, and potential leaks or water damage. If left unaddressed, roof curling can lead to further deterioration of the roofing system and more extensive repairs.
