Alabama summers are brutal on shingles. Here's exactly why.
Asphalt softens
Sustained 100°F+ attic temps soften the asphalt that holds granules in place.
Granules separate
Once granules wash off, the underlying asphalt is exposed to UV and degrades fast.
Curling and cupping
Heat-cycled shingles begin to curl at the corners as they age.
Solution: ventilation
Balanced ridge and soffit ventilation can drop attic temps by 20–30°F, dramatically extending shingle life.
