At what point should you replace an asphalt shingle roof?
Short answer. Replace an asphalt shingle roof when its condition says it is worn out, which for most Georgia homes falls around 15 to 20 years for 3-tab and 20 to 30 for architectural shingles, or sooner after hail or wind damage. Insurance age rules, plans to sell or add solar, and the season can tip the timing within that window.
Milestones to watch
- 3-tab roofs around 15 years. Thin shingles lose wind resistance as they age, and many original builder roofs are 3-tab.
- Architectural roofs around 20 years. Start yearly checks, especially of the south and west slopes.
- Insurance age thresholds. Some insurers change how they settle roof claims, or decline to renew, once a roof passes a certain age. Know your policy before a storm; see roof age and insurance.
- After significant hail. Storm damage can make replacement necessary at any age, and may make it an insurance claim.
Life events that move the date
- Selling. An old roof can complicate a buyer's financing and insurance.
- Adding solar. Replace first if the roof has less than about 10 to 15 years left.
- Other exterior work. Gutters, siding or skylights are easier to coordinate with a reroof.
Choosing the season
Georgia allows roofing nearly year-round. Late spring through fall offers the most warm, dry days, which help shingles seal quickly, though demand peaks after spring hail. Mild, dry winter days above about 40 degrees work too, with hand sealing where needed. What you should avoid is carrying a roof that is already failing through another storm season.
