Repairs are priced by the job, not by the square. What drives the number is the height and pitch of the roof, how much has to come apart to reach the problem, and whether the damage spread into the deck.
| Repair | Typical range | What moves it |
|---|---|---|
| Pipe boot replacement | $250 – $450 | Per vent |
| A few shingles replaced | $300 – $750 | Matching and access |
| Step or wall flashing | $500 – $1,400 | Length of wall |
| Chimney flashing | $700 – $1,800 | Size of chimney |
| Valley rebuild | $800 – $2,200 | Length and condition |
| Decking repair | $90 – $150 per sheet | Plus the shingle work around it |
| Emergency tarp | $350 – $900 | Size and timing |
| Ice dam steam removal | $500 – $1,400 | Length of the dam |
When a repair is the right call
A roof under about 15 years old with one clear failure, a boot, a flashing, a few wind-torn shingles, should be repaired. So should an older roof that's otherwise sound and simply has a bad detail. A good repair on a sound roof can buy many years.
When it isn't
If the shingles crack when you lift them, granules are piling in the gutters, there are leaks in more than one spot, or the roof has needed three repairs in two years, the money is better spent toward a replacement. We'll tell you if we think you're there. The repair or replace guide lays out the signs.
Questions readers ask
Is there a minimum charge?
Small repairs carry a minimum because setup and travel are the same for a big or small job. It's stated on the estimate.
Can I get a repair in winter?
Yes. Some repairs are temporary in deep cold and finished on a milder day.
Will a repair void my warranty?
Not if done properly. Keep the receipt and the photos.
