Hail, wind and attic heat
North Alabama sits in an active severe-weather corridor. Hail bruising does not always look like damage from the ground. Granule loss (shingles shedding the gritty coating that shields them from the sun) and cracks in the shingle mat show up as faster aging a year or two later. That is why a check after a storm matters, even when the roof looks fine.
Wind damage starts at edges and corners. Most wind losses we see begin at a poorly fastened drip edge, the metal strip along the roof edge, or a starter row of shingles that was never properly sealed down.
Attic heat here is extreme, and it cooks shingles from underneath. A roof without enough intake and exhaust ventilation ages measurably faster than the same roof properly vented. It is the least glamorous part of a new roof, and one of the most important.
