Homeowners ask me all the time how many years they’ve really got left on their roof. Here’s the thing: a “30-year shingle” doesn’t mean 30 years in Georgia. Our heat, humidity, and summer storms wear roofs down faster than the label promises. Most asphalt roofs around here hold up 18 to 22 years, even with good attic ventilation.
Age isn’t the only clue, though. Granules piling up in your gutters, shingles curling at the edges, or a musty smell in the attic all show up before a leak ever does.
I saw this firsthand on a roof that was only six years old but looked twenty. Delamination, granule loss, and rusting exposed nail heads all over it — none of that should happen that early. It almost always traces back to poor installation, manufacturer defects, or ventilation that was never dialed in.
