Bellevue, King County
Chimney flashing repair in Bellevue runs $329–$1,495. Resealing flashing that is sound but has lost its seal sits at the bottom of that range; tearing out rusted or loose metal and installing new step flashing, counter flashing and, where the chimney is wide, a cricket sits at the top. Flashing is where roof and chimney meet, and it is where many chimney leaks begin.

Bellevue roofs change a lot from one neighborhood to the next, from low-pitch roofs on older Lake Hills houses to steep, broken-up rooflines elsewhere in the city. Every one of them has the same weak point: the joint around the chimney, where metal has to bridge two materials that move differently through wet and dry seasons.
A direct-vent gas fireplace can terminate horizontally through an outside wall or vertically through the roof. When it goes up, the vent pipe crosses the roof deck just as a chimney does, and that penetration needs its own flashing.
In Bellevue's multi-unit buildings, which hold 31,860 of the city's 64,688 housing units by the state's 2020 count, that roof is usually shared. A leak at a vent termination there is repaired with the building's management, and we can document the problem for them.
Every chimney flashing repair we do in Bellevue includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowThe usual Bellevue flashing failures are caulk that has dried and pulled away, counter flashing that was surface-mounted instead of set into the mortar joint, and roofing replaced without new chimney flashing. Water then shows up as a ceiling stain beside the chimney or a drip in the attic during heavy rain. We trace the path before quoting, so you are not paying to reseal a leak that actually comes from the crown.
On Washington DNR's maps, the Seattle fault runs under Bellevue. The same agency rates the odds of a deep Puget Sound earthquake reaching magnitude 6.5 or more, within the next 50 years, at 85 percent.
A masonry chimney and a wood-framed roof respond differently to shaking, and the flashing is the joint between them. CSIA recommends a Level 2 inspection after a seismic event, which includes the roof, and torn or lifted flashing is one of the things that visit is meant to catch.
We look at the chimney from the roof and from the attic, and confirm the water is getting in at the flashing, not through the crown or brick.
A reseal, a partial replacement or full new flashing with a cricket. The quote explains which one your roof needs.
Step flashing goes in course by course with the shingles, and counter flashing is cut into the mortar joints and sealed.
We check the finished work, clean up, and send photos so you can see how the joint was built.

Washington's residential code, following IRC R1003.20, calls for a cricket wherever a chimney measures more than 30 inches wide parallel to the ridge. The cricket is a small peaked roof on the uphill side that splits the water around the chimney instead of letting it pool against the brick, and it is flashed and counterflashed like the rest.
Flashing is one of the four inexpensive defenses CSIA recommends against water damage. It matters here because the wet months are long: from October on, and in December and January western Washington often records precipitation on 20 days a month or more.

$329–$1,495. Resealing sound flashing is at the low end; new step and counter flashing, or a cricket on a wide chimney, is toward the top.
Usually, yes. Reusing old chimney flashing under new shingles is a common source of leaks. If your roofer is not replacing it, we can coordinate the chimney side.
A stain right beside the chimney that appears during heavy rain points to flashing. Damp brick higher up points to the crown or the brick itself. We confirm before quoting.
