Roof Leak and Chimney Repair Cost (2026): Flashing, Crickets, Crowns, Chases and Liners, With Labor Hours
What roof leak and chimney repairs cost a contractor in 2026: shingle and flashing leaks, chimney reflashing and crickets, crowns, caps and chase covers, framed chase reclads, liners and inspections, skylights and kickouts, with the code and labor hours.
The assumptions
This model assumes
- Asphalt shingles and a brick chimney unless stated
- Permits only where Clamp carries one
- Job cost before markup: labor and materials, no markup or tax
- Prices from Clamp's catalog on November 5, 2026
The model, step by step
Priced through Clamp's catalog on November 5, 2026, with labor hours. Every price in this guide is job cost before markup: what the labor and materials cost you, before your overhead and profit. The ballpark price ranges add a typical markup to that. A leak repair is a trip, a ladder, finding the leak, and a small area of shingles, underlayment and sealant.
| Repair | Job cost | Hours |
|---|---|---|
| One spot, asphalt shinglesShingles, underlayment, sealant | $424 | 3 |
| One spot, new flashingWall, pipe or vent flashing | $535 | 3 |
| Three spotsSame roof | $1,271 | 9 |
| One spot, metal roofFasteners, sealant, trim | $521 | 4 |
| One spot, flat membranePatch and seal | $456 | 3 |
Most chimney leaks are flashing. Clamp prices a reflash (tear out the old flashing and the shingles around it, new step flashing and counterflashing cut into the mortar or surface-mounted, shingles back) at $800. A bead of sealant over the old metal is a reseal, a different and cheaper job. A chimney wider than 30 in. also needs a cricket on its uphill side (IRC R903.2.2): a framed saddle that sends water around the chimney. NRCA recommends one at 24 in. and wider.
The chimney
Drawn for this guide in the style of Quick Clamp's sketch pad: a brick chimney through the roof with its cap, crown, step and counterflashing and a cricket on the uphill side. Demo data.
| Repair | Job cost | Hours |
|---|---|---|
| ReflashStep and counterflashing | $800 | 5 |
| Reflash and a new cricketCricket by a sub, no hours | $1,550 | 5 |
The crown sheds water off the top of a masonry chimney; a cracked crown lets it into the brick. A framed chase gets a metal chase cover instead. When the brick above the roof is spalled or loose, the top courses come down and go back up.
| Repair | Job cost | Hours |
|---|---|---|
| Crown rebuild, 8 sq ftDemo, form and pour | $1,132 | 12 |

| Rebuild the top 4 ftBrick above the roofline | $2,630 | 25 |
| Chase cover, stainlessCustom, installed | $825 |
A Level 1 inspection covers what you can reach without tools. A Level 2 adds the attic, crawlspace and roof, including the crown, flashing and cricket, and a video scan of the flue. CSIA recommends a Level 2 when the house is sold, when an appliance or fuel changes, before relining, and after a chimney fire or a weather or seismic event.

A framed chase leaks through the cover, the siding or the flashing at the roof, and the water goes into the sheathing, where nobody sees it until it's soft. Clamp prices a chase reclad as roof work: the tear-off, new sheathing where the words say it's going, siding, wrap and corner trim at 1.3x for roof jacks and fall protection, the step and counterflashing the tear-off disturbs, and the cover.
The chase
Drawn for this guide in the style of Quick Clamp's sketch pad: a framed chase above the roof with a chase cover, lap siding, corner trim and flashing at the roof. Demo data.
| Cladding | Job cost | Hours |
|---|---|---|
| Vinyl, all new sheathingWith a permit allowance | $4,546 | 24 |
| Hardie, painted, all new sheathingWith a permit allowance | $5,873 | 35 |
A kickout at the bottom of a roof-to-wall intersection turns the water away from the wall instead of letting it run behind the siding. The IRC requires one (R903.2.1 since 2015); a missing kickout is a common source of wall rot under a roof edge.
| Repair | Job cost | Hours |
|---|---|---|
| Replace a skylightFixed, new flashing kit | $1,660 | 8 |
| Two kickout flashingsWhere a roof meets a wall | $526 | 4 |
Repairs mostly follow local rules; check the permit threshold before you quote.
What to check
PermitsIRC R105.2.2 exempts ordinary repairs, but not cutting away a wall or structural work, and many cities permit all reroofing. Bay City, Michigan prices roofing permits by job value from a $25 base.
RecoveringThe 2024 IRC moved the recover rules to R908.4: no recover over two layers, a water-soaked or deteriorated roof, or slate and tile.
FloridaSince May 27, 2022, when 25% or more of a roof built, repaired or replaced to the 2007 Florida Building Code or later is repaired, only the repaired portion must meet current code.
CricketsChimneys wider than 30 in. get a cricket (R903.2.2).
KickoutsWhere a roof eave meets a sidewall, kickout flashing (R903.2.1).
A framed chimney chase about 3 x 4 ft and 10 ft above the roof on average (140 sq ft of siding) is leaking. The T1-11 comes off with the rotted OSB; the chase is re-sheathed, wrapped and sided in Hardie lap with Hardie corner trim, painted, reflashed, and capped with a custom stainless chase cover. Clamp priced it at $5,123 job cost before markup, 35 person-hours, without a permit; ask the building department, since the sheathing comes off. Both sides of a 3 x 4 chase are wider than 30 in.: if it has no cricket, add one, $750 more.
