Roof repair or replacement: how to decide
Updated
The article
The short answer
Repair when the damage is in one area, the rest of the roof is in good shape and the deck underneath is solid. Consider replacing when problems show up across the roof, leaks keep coming back after repairs, or the roof is near the end of the life its maker rates it for. Have a local roofer look at it in person before you decide.
Signs a repair is enough
- A few missing or damaged shingles in one spot, after a storm or a fallen branch.
- A leak you can trace to one place, such as the flashing around a chimney, vent or skylight.
- The rest of the roof lies flat, with no curling, cracking or bare patches across it.
- The deck is solid underfoot, with no soft or sagging areas.
Signs it may be time for a new roof
- Shingles curling, cracking or missing across many parts of the roof.
- Lots of granules in the gutters, or dark bare patches on the shingles.
- Leaks that come back after they’ve been repaired.
- A sagging roofline, or daylight through the roof boards in the attic.
- Damage across most of the roof after a major storm.
Questions to ask the roofer
- What exactly is wrong, and can you show me photos?
- What would a repair fix, and what would it leave as it is?
- How much life does the rest of the roof have left?
- Will new shingles match the old ones?
- Who pulls the permit, if the town requires one?
- What warranty comes with the work, and can I have it in writing?
Get it in writing
Ask for a written estimate that lists the work, the materials, and what happens if the roofer finds rotten decking once the old shingles are off. Two written estimates for the same work make it easier to compare.

Questions, answered.
Can I put new shingles over the old ones?
Sometimes. Some building codes allow one extra layer and some don’t. A second layer adds weight and can hide problems in the deck, so many roofers recommend taking the old shingles off. Ask your roofer and your town what’s allowed.
Will a repair match the rest of my roof?
Not always. Shingle colors and styles change over time, so a patch on an older roof may show. Ask to see a sample before the work starts.
Is it safe to check the roof myself?
Look from the ground or from a window, with binoculars if you have them. Leave walking the roof to a roofer with the right safety gear.
