Roof repairs are priced differently from new roofs. Most roofers charge a minimum or service call, then price the work by the damaged area or by the job: replacing a few shingles, sealing a leak, fixing flashing or patching a flat roof.
Enter the size of the damaged area, pick your roof type and add flashing, decking or a tarp if needed. The estimator gives a low, typical and high price with the labor split. For a roof near the end of its life, compare it with the cost of a new roof.
How the roof repair cost estimate works
- Enter the damaged area in square feet (or roofing squares).
- Multiply it by the installed price per sq ft for the material you chose.
- Adjust for roof pitch and access and your local cost level.
- Add the extras you ticked, such as removal, and any permit fee.
- Show the result as a low, typical and high total, split into materials, labor and fees.
Estimate the damaged area from the ground or attic: a single missing shingle is about 3 sq ft, a bundle covers about 33 sq ft and a square is 100 sq ft. Roofers usually round small repairs up to a minimum charge.
Roof Repair Cost by material
| Material | Installed per sq ft | Labor share | Notes |
|---|---|---|---|
| Asphalt shingle | $3.50–$7.00 | 70% | Most common and cheapest to repair. Matching old shingle color can be hard. |
| Metal | $5.00–$12.00 | 60% | Panels, fasteners and seams. Loose or rusted screws are a common cause of leaks. |
| Flat roof (EPDM, TPO or modified bitumen) | $4.00–$11.00 | 65% | Patches and seam repairs. Ponding water usually points to a bigger problem. |
| Clay or concrete tile, slate | $8.00–$25.00 | 65% | Fragile to walk on and slow to repair; often the underlayment is the real issue. |

What affects roof repair cost
- Roof material. Asphalt shingles are the cheapest to repair. Tile and slate are fragile and slow to work on, so the same area costs two to four times more.
- Cause of the leak. Many leaks come from flashing around chimneys, vents and skylights rather than the shingles themselves. Finding the source is part of the cost.
- Hidden damage. Water that has soaked the decking or framing means replacing wood as well as roofing, which adds to the bill.
- Pitch, height and access. Steep and tall roofs need extra safety equipment and take longer.
- Emergency work. Storm calls, nights and weekends often cost more, and a temporary tarp may come before the real repair.
Frequently asked questions
How much does roof repair cost?
A typical repair to about 100 square feet of asphalt shingle roof costs roughly $600 to $1,200 including the service call. Small fixes like replacing a few shingles often land at the roofer's minimum of about $250 to $500.
How much does it cost to fix a roof leak?
Most leak repairs cost a few hundred to about $1,500 on an asphalt roof, depending on the cause. Flashing repairs add about $200 to $900, and rotten decking adds more.
How much does it cost to replace shingles?
Replacing a small patch of shingles usually costs the minimum charge. Larger sections run about $350 to $700 per square (100 square feet) plus the service call.
Should I repair or replace my roof?
Repair makes sense when damage is limited and the roof has plenty of life left. If the roof is near the end of its life, leaks keep coming back or damage covers more than about 30% of it, replacement is usually the better value.
