Repair or Replace? How to Read Your Roof's Real Condition

Roofing

Half the roofs we're asked to replace shouldn't be replaced yet — and a meaningful share of the roofs we're asked to patch are past saving. Here's how the decision actually works when nobody is trying to sell you anything.

The age question comes first

Three-tab asphalt shingles are engineered for roughly 15–20 years; architectural shingles 20–30; metal, tile, and slate far longer. A 6-year-old roof with a leak almost always deserves a repair. An 18-year-old asphalt roof with a leak deserves honest math: every dollar spent patching buys time on a system that's already near the end.

Signs a repair is the right answer

Localized damage with a clear cause: a missing shingle course after one wind event, a failed pipe boot, flashing that pulled away at a chimney, a puncture from a falling branch. If the surrounding field of shingles is sound — flexible, granule-covered, lying flat — a targeted repair restores the system.

Signs the roof is at the end

Pattern failures, not incidents: leaks appearing in different rooms across seasons, widespread granule loss exposing dark substrate, shingles that crack when lifted, curling edges across whole slopes, daylight or moisture staining in the attic, and a repair-over-repair history where new leaks follow every fix. Storm damage documented across multiple slopes after hail also typically triggers replacement — often insurance-funded.

The math nobody shows you

A fair framework: if repair costs exceed roughly 25–30% of replacement cost on a roof past two-thirds of its expected life, replacement usually wins — the remaining system will keep generating repair bills while home-sale inspections and insurance renewals start counting the roof against you. Under that threshold on a younger roof, repair wins comfortably.

Get the answer in writing, with photos

Any contractor recommending replacement should show photographic evidence and be willing to state, in writing, why repair is not appropriate. That's our standard on every free inspection — and when repair is the right answer, that's the answer you get. If it is time, here's exactly what a proper replacement includes.
