Newcastle, King County
Our Newcastle price for chimney flashing repair runs $330 to $1,500. At $330, counter-flashing that pulled out of its mortar joint is set back and resealed. At $1,500, rusted metal comes off a wide chimney on all four sides and fresh step pieces and counter-flashing go on. A technician on the roof, camera in hand, decides which job it is; the figure is written only after that.

Where a chimney pierces the roof deck, a slot is left open on purpose and covered by folded sheet metal: the flashing. Masonry and framing shift at different rates, which rules out a rigid joint, so the metal is lapped in two layers: step flashing woven into the shingles, counter-flashing let into the brick joints above. A leak starts when either layer lifts, rusts through, or was replaced with a bead of roofing tar by a previous owner.
Two drainage basins divide Newcastle, as its hazard annex lays out: Coal Creek's on one side of a steep valley, and on the other that of May Creek, the stream that marks the boundary with Renton. What is true of the ground is true of the roofs built on it. Where a hillside house carries a long, steep roof plane, every gallon that lands above the chimney has to pass around it on the way to the gutter.
November brings about 8.3 inches of rain here by WeatherSpark's estimate. On a steep plane that water arrives at the back of the chimney fast and in volume, which is why we always inspect the up-slope side first. A back pan that is too shallow, or a missing saddle on a wide stack, lets water pool against the masonry and climb under the counter-flashing.
Every chimney flashing repair we do in Newcastle includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowNewcastle tests that joint for most of the year. An average November has some 17 wet days by WeatherSpark's tally and has the wind blowing from the south from early September to early July. Rain carried on wind does not fall straight down past a chimney; it is pushed against the up-slope side and along the laps. About a third of the city's housing also dates from the 1980s and 1990s, per Census estimates, which is old enough for a roof to have been replaced once, and a re-roof that kept the tired flashing underneath is a well-known way for a chimney to start leaking.
The up-slope side of a chimney is a natural shelf. Needles, cones and leaves slide down the roof and stop there. Newcastle's annex says many homes border native growth or densely wooded natural areas, so the shelf fills quickly. Once it does, rainwater backs up behind the pile instead of draining around the chimney.
Oregon State University Extension explains what follows on a roof: moss traps debris and holds moisture, so the surface underneath stays wet far longer. Metal that sits under a wet mat for years corrodes from the top, and sealant along the counter-flashing stays soft. Part of every flashing repair we do in Newcastle is clearing that shelf and showing the owner where it forms, because the new metal will face the same pile next autumn.
Stains are followed uphill from the inside, then matched to the flashing section above them on the roof.
Shingles around the chimney are lifted and old sealant is removed, so the true condition of the metal is visible.
Sound metal is re-set and sealed; failed metal is replaced with new flashing bent to fit the chimney.
A hose is run over the repair, starting low and moving up, while someone watches from inside.

The repair is completed, then handed over with before-and-after photos of every item.
No. A cracked crown, porous brick or a missing cap can all produce a stain in the same place. Tracing the path before quoting is what keeps you from paying for the wrong repair.
It changes what goes near it. Zinc sulfate, a common moss killer, eats copper flashing and gutters, as Oregon State University Extension cautions, so we note that on the report for whoever maintains the roof.
$99 plus tax buys the inspection of one chimney; accept the flashing quote and the invoice is reduced by that sum.
