The answer to 'why is my skylight curling shingles' is that the skylight is causing heat buildup and uneven expansion, leading to the shingles curling around the skylight. Skylights can create hot spots on the roof, causing the shingles to dry out, crack, and curl over time. This is a common issue that requires attention to prevent further damage.
The symptoms of curling shingles around a skylight include visible gaps or spaces between the shingles and the skylight frame, as well as a wavy or uneven appearance to the shingles. If left unaddressed, this can lead to leaks, moisture damage, and even structural issues with the roof.
