Nobody wants to replace a roof early — and nobody wants to pour repair money into one that’s finished. After 125+ replacements, here is the framework we use on every inspection, and the one we’d want applied to our own homes.
Five signals the roof is done being repaired
1. Age plus symptoms. A 20-year shingle roof at year 18 with curling tabs and granule loss isn’t “holding on” — it’s spending its last seasons. Age alone never decides, but age with visible wear almost always does.
2. Granule loss you can measure. Check your gutters: piles of sandy grit mean the UV armor is gone. Bald patches on south and west slopes confirm it. Once granules go, shingle aging accelerates fast.
3. Soft or spongy decking. If the roof feels soft underfoot in spots, moisture has reached the wood. Decking repairs mean opening the roof up — and once you’re opening it, a full system usually costs less per remaining year than patching around rot.
4. Repairs stacking up. Our rule of thumb: if quoted repairs exceed 25–30% of replacement cost — or you’ve called a roofer twice in two years — replacement is the cheaper decade, not just the better roof.
5. A second layer hiding underneath. Overlay jobs trap heat, hide deck damage, and void most manufacturer warranties. If your roof has two layers, the next job must be a full tear-off — plan for it on your terms, not after a leak forces it.
What replacement actually involves
Most Austin homes take one to two days: tear-off to the deck, deck repairs, synthetic underlayment, new flashing at every penetration, ridge ventilation, and a magnetic nail sweep of your yard — twice. You get photos of each layer, a written workmanship warranty, and manufacturer registration in your name. The only decision you make under pressure should be the shingle color.
