Kenmore, King County
Chimney flashing repair in Kenmore runs from $375 to $1,500. Resealing a sound set of flashings sits at the bottom of that range; full replacement of corroded metal, plus a new cricket on a wide stack that never had one, lands near the ceiling of it. We confirm the leak is at the flashing before recommending either.

Where a chimney passes through the roof is the most complicated joint on most Kenmore houses. Many older homes here have been reroofed once or twice since they were built, and roofers on a tight schedule tend to keep the old metal, smear caulk over it and move on. The bill for that shortcut arrives a few winters later, as a brown ring near the chimney breast.
Census estimates put the median Kenmore housing unit in 1985, with about 22.5 percent built in the 1980s and a larger share in the 1960s and 1970s. The King County survey of the city's postwar homes found them to be mostly Ranch and Split Level designs.
A house of that age has usually outlived its first roof. Split-levels in particular often have a chimney that meets the roof at an awkward point, and the flashing there is where we most often find patched sealant from a previous reroof.
Every chimney flashing repair we do in Kenmore includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowThe telltale Kenmore leak appears in the second or third week of a wet stretch, near the chimney breast or in the attic beside the stack. Sealant along the top of the counter flashing has cracked, the step flashing has rusted through, or needles have banked up on the uphill face of a broad stack that lacks a cricket, damming water against the joint.
WeatherSpark's Kenmore data show the breezier half of the year and the rainy half lining up almost exactly: both begin in October and end in late April. Climate records from the Western Regional Climate Center add that, in the lowlands around the lake, wet-season wind comes mostly out of the south or southwest.
Rain carried sideways by wind is what finds a gap in flashing. On a chimney that faces south or southwest, those are the joints that get tested hardest every winter.
We check the attic, then water-test the flashing on its own so the crown and brick are not blamed or missed.
Old sealant and damaged metal come off, and the shingles around the stack are lifted carefully to reach the base layer.
Each step piece is interleaved with a shingle course; the counter pieces are cut into a mortar joint and lapped over them.
A hose goes over the new joint for a second test, and you receive pictures of all four sides, uphill face included.

Washington's 2021 residential code, at R1003.20, says a stack whose width along the ridge line exceeds 30 inches needs a cricket, a small peaked diverter, unless the stack itself intersects the ridge. The cricket must be flashed and counterflashed like any other roof-to-chimney joint.
On wide brick chimneys, an absent cricket explains a good share of the leaks that keep coming back. When we build one, it follows the 2021 residential code, the edition King County has enforced since mid-March 2024.
Kenmore is a city on the northernmost shore of Lake Washington, where the Sammamish River meets the lake, on Lake Washington, with Ranch and Split Level houses from the 1950s and early 1960s beside newer homes, for a median build year of 1985. We work every part of it — Uplake Terrace included.

$375 to $1,500. Resealing sound metal costs least; full replacement, steep roofs, wide chimneys and a new cricket push toward the top. The quote says which one you need.
Sometimes it is the flashing, sometimes the crown or the brick above it. We test each separately so you are not paying to fix the wrong part.
Yes, in most cases. We work on the shingles immediately around the chimney and leave the rest of the roof alone.
