Maple Leaf, King County
Repairing chimney flashing in Maple Leaf costs $375 at the low end and $1,495 at the high end. Resealing a counterflashing joint that has opened is a morning's work. Stripping shingles back, replacing step flashing on every side and building a diverter behind the chimney is a full day or more, and the roofing material, whether composition, cedar or metal, changes the labor.

In HistoryLink's sketch the neighborhood is a rough triangle, Northgate Way across the top and Interstate 5 down the west side, and Wikipedia carries the neighborhood south to NE 75th Street. Inside those lines the land rises to one of the highest points in Seattle. A roof here has less around it to break the weather than a roof in a valley, and the seam where chimney meets shingles is the part of it most likely to leak.
Seattle's residential code draws a line at 30 inches. When a chimney's side parallel to the ridge is wider than that, R1003.20 requires a cricket behind it, sized according to the roof's pitch. Narrower chimneys may go without. The rule was written for new construction, and a house finished before it applied may have a broad chimney with nothing behind it but a flat strip of metal.
Homes old enough for that are numerous in the Census area that includes Maple Leaf, where the 1940s contributed 14.2 percent of today's homes and the decade after them 14.3 percent. On a hill that tops out at 466 feet, the water arriving at the back of a chimney comes with wind behind it. Where we find repeated leaks behind a wide stack, on its uphill side, we quote the cricket as well as the reflash, with the reasons, and the owner chooses between a repair and a correction.
Every chimney flashing repair we do in Maple Leaf includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowWind decides which side of a chimney leaks. WeatherSpark shows Seattle's wind arriving mostly from the south between September 20 and July 3, and in the Western Regional Climate Center's state narrative the Puget Sound lowlands get their wet-season wind out of the south or southwest. Rain therefore hits a chimney's south and west faces at an angle and is pushed up under the metal there. Those are the sides we test first.
With someone watching in the attic, water is run over each side in turn until the drip appears.
Roofing is opened around the chimney so every piece of flashing can be judged, not just the visible edge.
New step pieces lap each course of shingles. The counterflashing above them is set into the mortar joint, not glued to the face.
The hose comes out again. Shingles are relaid and you receive photos of all four sides.
