How often should I replace my roof?
Short answer. Replace it when it is worn out, not on a set date: for most Georgia homes with architectural shingles that is around 20 to 30 years, and 15 to 20 for 3-tab. Replace sooner if storm damage is found, if you are adding solar to a roof past mid-life, or if your insurer will not renew coverage because of the roof's condition.
Start with what you have
Find out the roof's age from permit records, the seller's disclosure or old inspection reports, and identify the material. Flat, single-layer tabs with even slots usually mean 3-tab shingles, which are older technology and shorter-lived. Thicker, dimensional shingles are architectural. Metal, tile and slate follow very different timelines.
Then factor in your plans
- Selling in the next few years? A roof near the end of its life will come up in the buyer's inspection and often in negotiation.
- Adding solar? Panels typically stay up 25 years or more, so a roof with less than about 10 to 15 years left should be replaced first. See replacing your roof before solar.
- Insurance notices? A letter about roof condition or an inspection request is a reason to get your own inspection right away.
- Staying long term? Consider upgrades like impact-resistant shingles or better ventilation when the time comes.
And your roof's exposure
South and west slopes in full sun age fastest. Roofs under pines and hardwoods deal with debris, damp shade and falling limbs. A house on an open hilltop sees more wind. Two identical roofs in the same subdivision can reach the end of their lives years apart.
