Green Lake, King County
Chimney flashing repair in Green Lake costs $375 to $1,495. At the low end, a strip of counter-flashing has worked loose from the brick and needs to be set back and sealed. At the high end all the old metal comes off, and new step pieces, new counter-flashing and an uphill saddle go on. Roofing type, pitch and the width of the chimney move the figure in between. We find the leak path first, during a $99 plus tax inspection whose cost is applied to the flashing work when the quote is accepted.

Width matters more than most owners expect. Seattle's residential code, section R1003.20, requires a cricket, the small peaked saddle that splits runoff, once a chimney's width along the ridge line passes 30 inches. A broad stack without one has a flat pocket on its uphill side where water and litter sit against the metal. Roof replacement is the other moment flashing gets disturbed. Seattle lets a house or duplex be reroofed with no permit, provided the building envelope stays as it was and the new roof is a match for the old in quality, which means a Green Lake roof can be redone with nobody but the roofer looking at how the chimney was tied back in.
Moss control and chimney flashing meet in one warning issued by Oregon State's Extension service: a zinc sulfate moss killer will corrode copper, and so has no place on a roof whose gutters, downspouts or flashing are made of it. Copper is one of the metals chimney flashing is made from, and a homeowner treating a shaded roof near Green Lake Park, 323 acres of it by HistoryLink's count, may not know which metal is under the grime.
We identify the flashing metal as part of every repair and write it on the invoice, so the next person to treat the roof has the information. Where moss has grown along the uphill side of the stack, we clear it by hand before judging the metal; flashing that looks rotten under a wet green mat is sometimes sound, and flashing that looks fine can be pitted through.
Every chimney flashing repair we do in Green Lake includes:

Book nowRain reaches a Green Lake chimney from a consistent side. The Western Regional Climate Center's narrative for Washington describes lowland winds around Puget Sound that turn with the calendar: southerly or southwesterly while the rains last, northwesterly in summer, and averaging below 10 mph. Winter water is therefore pushed against the south and west faces of the stack and into whichever flashing joint faces that way. When a ceiling stain appears on the opposite side, the entry point is often still on the weather side, and the water has traveled along the framing.
We follow staining upstream and inspect each flashing piece instead of assuming the lowest joint is the culprit.
Shingles beside the chimney are lifted so the hidden step flashing can be seen and replaced if needed.
New pieces are lapped shingle-style, the counter-flashing edge is tucked into a cut joint, then sealed.
Water is run over the area from above while someone watches from below.

The repair is completed, then handed over with before-and-after photos of every item.
Sealant has a place at the reglet, but tar or caulk smeared over failed metal is a short patch. If the metal is corroded or badly lapped, it needs replacing.
Flashing is sometimes reused during a reroof or tucked in without counter-flashing. A new roof does not guarantee new metal at the chimney.
We lift and relay the shingles immediately around the stack as part of the flashing job. A wider roofing problem goes to a roofer.
