How long do shingle roofs last in Georgia?

In Georgia, a properly installed asphalt shingle roof typically lasts 20 to 30 years for architectural shingles and 15 to 20 years for 3-tab shingles, though actual lifespan depends heavily on local conditions. Georgia's combination of intense summer heat, high humidity, and frequent severe thunderstorms and hail can shorten a shingle roof's life faster than in milder climates. Proper attic ventilation, regular inspections, and prompt repair of storm damage all help a shingle roof reach the higher end of its expected lifespan.
