Short answer
Repair when the roof is still well within its expected life for your climate, the problem is isolated, and the shingles are still flexible. Replace when the roof is near the end of its life, damage is spread across several slopes, leaks keep coming back in different places, or a covered storm claim pays for it.
Signs a repair is enough
- One leak with a clear cause, such as a pipe boot or a flashing joint.
- A few shingles blown off a roof that's otherwise in good shape.
- Shingles still lie flat and bend without cracking.
- The roof has many years left for your climate.
Signs it's time to replace
- The roof is near or past its expected life for your climate.
- Shingles are curling, cracking or losing granules across the roof.
- Leaks appear in different spots after every storm.
- Storm damage covers multiple slopes.
- Your insurer won't renew or is moving the roof to actual-cash-value coverage because of its age.
The insurance angle
If storm damage is covered, a claim may pay for most of a replacement minus your deductible. For an older roof with storm damage, that often makes replacement the better choice. Some insurers also charge more, or pay less, for older roofs.

Buyers' inspectors flag aging roofs, and lenders and insurers may require repairs before closing. A roof inspection report helps you decide whether to repair, replace or offer a credit.
When to call a roofer
- You've had more than one leak in a year.
- Your roof is aging and you've had a storm.
- An insurer or buyer's inspector questioned the roof.

Common questions
How much of a roof can be repaired before replacing makes more sense?
When damage reaches roughly a quarter or more of the roof, or spans several slopes, replacement usually costs less over time than repeated repairs. Florida has specific rules on partial replacements tied to the building code.
Will a partial replacement match?
Rarely exactly. Sun-faded shingles look different from new ones, which matters on visible slopes.
