Heat does the slow damage. Attic temperatures in an under-ventilated Atlanta home can climb past 140 degrees in August, baking the asphalt from underneath and driving out the oils that keep a shingle flexible. Hail does the fast damage. North Georgia sits in an active spring hail corridor, and the storms that track through Cherokee, Cobb, and Forsyth counties from March into May drop stones big enough to bruise a shingle mat without leaving a mark you can spot from the driveway.

Tree canopy adds a problem particular to this metro. Limbs scrape granules off the slopes they overhang, pine needles pack into valleys and hold water against the surface, and February pollen leaves a film that traps everything else. Our Atlanta roof inspection documents all three, and you get the findings on video rather than a verbal summary.
