Fremont, King County
Flashing repair around a Fremont chimney is priced $375 to $1,495. At $375 we are resealing: lifted counter-flashing pressed back into its joint, the groove refilled, a split corner soldered or patched. The four-figure end of the range is full replacement, with step flashing woven into the shingles on both sides, a new apron in front and a saddle behind. Chimney width, roof pitch and roofing material decide where between the two a given roof falls, and so does what we find under the old metal once it is lifted.

The city's 2010 inventory of Fremont picked 68 properties: 55 single-family houses, 6 double houses and 7 apartment buildings, the oldest from about 1895. One of the 55 is a 1911 Arts and Crafts house at 4221 Dayton Avenue N by the carpenter-developer John Creutzer. A house of that age has been reroofed more than once. At every reroofing the metal around the chimney meets one of two fates, proper renewal or burial under the new layer with a smear of mastic, and from the ground the two look the same.
During the wet season the prevailing wind over the Puget Sound lowlands comes out of the south or southwest, the Western Regional Climate Center's narrative says; WeatherSpark's Seattle data agree, showing a mostly southerly flow from September 20 to July 3. For Fremont, south is the water: Lake Union and the Ship Canal's cut, completed in 1916.
Rain that arrives on a south wind does not fall on a roof, it is driven across it. On a roof that faces the canal, water runs down toward the eave while the wind pushes it back up under laps and into the joint between metal and brick. This is the weather that exposes flashing held by caulk alone. The city's account of the 2006 windstorm has almost one City Light customer in two without electricity; storms of that kind are when owners first notice a ceiling stain that a calm drizzle never produced.
Every chimney flashing repair we do in Fremont includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowA new roof on a Seattle house or duplex is permit-exempt provided the envelope is left alone and quality does not drop below that of the old covering, so no inspector necessarily looked at the chimney joint the last time. One code point still applies there: past 30 inches of chimney width, taken parallel to the ridge, R1003.20 makes a cricket mandatory upslope of the stack, where it parts the runoff. Sound practice adds a second: counter-flashing belongs in a groove cut in the mortar, not glued to the brick face. A missing cricket and caulk standing in for a groove are the first two things we look for.
Crown, cap and brick leak too; we isolate the roof joint before quoting work on it.
Layers of patching compound come off so the real condition of each piece shows.
Sound metal is re-seated in a fresh groove; failed metal is cut out and new pieces lapped in.
A hose stands in for a storm while someone watches from the attic.

Choose a genuine opening on the crew's calendar. Confirmation is immediate.
Liner, crown, cap, flashing and masonry examined in order — each finding photographed.
One document, plain numbers, covering only the work your chimney genuinely needs.
The repair is completed, then handed over with before-and-after photos of every item.
The water does. We test the joint in sections with a hose and show you where it comes through. If the leak is in the field of the roof, we say so and you owe us nothing beyond the visit.
Leak tracing is done as an inspection of that chimney, $99 plus tax. If you then have us do the flashing work, the $99 is applied to it.
Counter-flashing, yes: it sits in the brick. Step flashing lies under the shingles, so replacing it means lifting and relaying the courses beside the chimney.
