Roof repair or roof replacement: how to decide

Start with the age and condition of the whole roof
Every roofing material has an expected life, and how close your roof is to the end of it matters more than any single damaged spot. When the whole surface is aging, with granules washing off, shingles turning brittle or curling across the field, a patch in one place buys little time while the rest keeps wearing out.
If you do not know the roof's age, check your closing papers or look up the permit history with your city; many cities publish permit records online.
Signs that need a roofer
- Active leaks, or water stains on ceilings or on the attic sheathing.
- Missing shingles that expose the underlayment or the deck.
- Heavy granule loss collecting in the gutters.
- Shingles curling, buckling or cracking across the roof.
- Soft spots in the deck, which a roofer should check, not a homeowner.
- Daylight showing through from the attic.
Usually cosmetic
- Moss or lichen in shady areas, worth cleaning before it lifts shingles.
- Algae streaks, which do not affect how the roof works.
- A single shingle lifted by wind, which is a repair.
- Gradual color fading.
When a repair makes sense
A repair fits a younger roof with damage in one area and the rest in good shape: wind-lifted shingles, failed flashing at a chimney or vent, a cracked pipe boot, or a hit from a falling branch. If a repair quote climbs toward the size of a partial replacement, ask why.
Insurance claims
If a specific storm caused the damage, your policy may cover it. File the claim before asking for replacement bids, so the adjuster sees the damage first. Read anything a roofer asks you to sign about your claim carefully, and check with your insurer before you sign it, since the rules on assigning claim rights vary by state.
What homeowners paid for a new roof
Nationally, the middle half of homeowners paid $7,050 to $17,590 to replace or add roofing, with the typical job at $11,740, according to the Census American Housing Survey. The roof replacement calculator shows the range for your region. We have no measured figures for repairs, so this guide does not give one.
Before you sign
Ask for photos or an inspection report that shows the damage. A roofer who recommends a full replacement without showing you why is selling, not inspecting. Get more than one opinion and more than one bid.
