How much does roof repair cost in 2026?
Repairs are priced by the size of the problem, not the size of the roof. Here's the US-average picture the calculator starts from. Your local market scales these bands up or down, and the calculator applies that automatically.
| Severity | Typical cost | Range | What it usually covers |
|---|---|---|---|
| Minor | $350 | $150 to $600 | A few shingles, a small leak, flashing reseal, a pipe boot |
| Moderate | $1,150 | $600 to $2,000 | Persistent leak, flashing replacement, valley work, a decking section |
| Major | $4,000 | $2,000 to $8,000 | Structural damage, sagging, large decking areas |
At the major end, stop and do the math before you commit. Spending $4,000 fixing a roof that costs $23,050 to replace can make sense on a young roof and almost never does on an old one. That's exactly the call the repair or replace tool is built for.
Roof leak repair cost
A small, contained leak usually lands in the minor band, $150 to $600. A leak that's been running for a while tends to price as moderate, $600 to $2,000, because water travels: by the time a stain shows on the ceiling, the flashing, underlayment, or decking around the entry point often needs work too. And the stain is frequently nowhere near the actual hole, which is why leaks get diagnosed on the roof, not from the driveway.
What makes roof repairs cost more
Your material. Repairs on tile and slate run about 2.5 times an asphalt repair. Copper and zinc run about 1.9 times, other metal roofs about 1.6, wood about 1.5, and synthetic about 1.3. Fragile materials, specialty labor, harder matching. Per square foot, cross-checked 2026 trade figures put asphalt repairs at about $4 to $10, tile at $11 to $30, and slate at $12 to $22.
Timing. An after-hours or storm-emergency call-out adds $200 to $500 on top of the repair itself. If it can safely wait until morning, let it.
Get an inspection before you commit
A repair estimate is a planning band, not a diagnosis. A professional inspection costs $100 to $400 and turns a guess into a scoped job. On anything beyond a minor fix, it usually pays for itself in avoided surprises, and it's the reliable way to catch hidden decking damage before it becomes a change order.
Frequently asked questions
How much does it cost to fix a roof leak?
Usually $150 to $600 if it's small and contained, and $600 to $2,000 if it's been leaking a while. The difference is what the water did on its way through.
How much does a roof inspection cost?
Typically $100 to $400. It's the best money in roofing: a diagnosed scope beats a guessed one, and every serious repair or insurance conversation starts with it.
When should I stop repairing and replace?
When a repair would top about 30 percent of replacement cost, when the roof is past about 20 years, or when fixes have become a subscription. Each repair on an old roof buys less time than the last one.
