Wind and rain share a calendar here. WeatherSpark's windier season for Renton lasts about 6.2 months, October 17 to April 22, almost the same span as the wet one, and for about 9.9 months of the year the wind comes most often from the south. Flashing stands in the middle of that: step pieces laced into the shingles, counter flashing tucked into the brick above, and sealant that ages a little every winter. We follow the water back to where it enters, lift whatever has let go, and reseal metal that is still good or install new metal where it is not.
Snoqualmie is the exception to the south-wind rule. WeatherSpark finds its wind coming most often from the east between about December 4 and February 25, and the city's hazard annex says windstorm risk is most frequent in October and November, when trees topple and power fails. On a house there, the east face of the chimney earns the same scrutiny the south face gets in Renton.
Flashing leaks are slow and private. Water tracks along the roof deck, soaks insulation and stains a ceiling several feet from where it got in, often weeks after the storm that started it.
Rot is the real cost. Framing beside a chimney that stays damp softens out of sight, and the first visible clue may be a sagging ceiling. Exposure tells us where to look. The Western Regional Climate Center finds that the hardest winds west of the Cascades come in late autumn and in winter and blow chiefly from the south and southwest, with speeds in the interior valleys expected to reach 40 to 50 mph each winter, so rain is driven hardest against those sides of the stack. On a wide chimney below the ridge we also check for a cricket, a little peaked saddle on the uphill side that sends runoff to either flank. And a caution if you treat roof moss yourself: Oregon State University Extension rules out zinc sulfate wherever gutters, downspouts or flashing are copper, since zinc eats into that metal.
How it works
The ceiling mark shows where water arrived; the roof shows where it started.
Brittle sealant and lifted metal come off so the condition underneath is clear.
Good metal keeps its place with new sealant; worn metal is replaced, both layers.

Serving Renton, Newcastle, Snoqualmie & Maple Valley
Flashing work costs $330–$1,500 with us. Resealing serviceable metal is the lower figure. Replacing both layers all the way around, or building a cricket, is the upper one.
A stain near the chimney that grows during windy rain suggests flashing. Proof takes a trip to the roof and the attic to trace the path, and that tracing opens every flashing visit we make.
If the leak can wait, yes: with shingles already off, new flashing goes in cleanly. Be aware that Renton requires a re-roof permit on a single-family home when the sheathing is replaced, and that Snoqualmie requires a permit for reroofs. Your roofer normally handles it.
It buys a few weeks. Tar hardens, splits and conceals the joint, so the next leak is harder to locate. Metal set into the mortar with a flexible sealant is the durable answer.
