Chimney Flashing Repair in Snoqualmie, WA

Chimney flashing repair in Snoqualmie runs $330 to $1,500. The lower figure is a reseal: the metal is sound and only its sealant has given up. The upper figure is a full replacement, with the failed pieces stripped and fresh step and counter flashing fitted on every side of the stack. These metal strips close the seam between stack and shingles, and that seam is the first place we look when a ceiling stains near a fireplace.

Why Snoqualmie homes need chimney flashing repair

Snoqualmie gives that joint a hard life. The city's hazard annex counts one to two rain events a year heavy enough to cause local flooding and road closures, and a significant snowfall about once a year. A drift lodged behind the stack, on its upslope face, thaws over days and probes each overlap in the metal. Most of the town's houses were built between 2000 and 2019, which means much of the original flashing and its sealant is now old enough to have dried, shrunk or lifted.

Sixty-one inches a year, by the city's own count

Snoqualmie's 2020 hazard annex puts annual precipitation since 1931 at 61.25 inches, and counts 11.5 inches of snowfall in the November-to-April months. WeatherSpark's model adds the calendar: a windier stretch from about October 23 to March 30, with December the windiest month.

All of that water runs down the roof, and a chimney stands in its way. Flashing has to turn the flow around the stack without letting any behind the metal. With this volume, a lap that is half an inch short or a bead of sealant that has split will show up indoors within a season or two. We test our repairs with running water for that reason.

Your chimney flashing repair in Snoqualmie: what's included

Every chimney flashing repair we do in Snoqualmie includes:

  • Water path followed from the indoor mark up to its entry point
  • Step, counter and apron flashing checked piece by piece
  • Dried sealant removed and joints resealed where metal is sound
  • New flashing cut, lapped and set into the mortar joint when needed
  • Uphill side checked for a diverter where water piles up
  • Hose test and photos once the work is done

Signs you need chimney flashing repair in Snoqualmie

  • A yellowish halo on the drywall next to the stack
  • Attic framing wet beside the chimney while it rains
  • Metal lifting away from the brick or siding
  • Black roofing tar troweled where the stack meets the shingles
  • Leaks that appear only when wind drives the rain

Why Snoqualmie homes need it

Roof work and flashing go together. Snoqualmie's permit page lists reroofs among the jobs that need a city permit, and a reroof is the moment chimney flashing is most often disturbed or reused when it should have been replaced. If your roof is being redone, ask who is responsible for the chimney. One caution on moss treatments, common under these trees: if any flashing, gutter or downspout on the roof is copper, keep zinc sulfate away from it. Oregon State University Extension gives the reason: zinc eats copper.

Your chimney flashing repair in Snoqualmie, step by step

  1. 1

    Follow the water

    We start at the stain, go into the attic if there is access, and work up to the exact spot on the roof.

  2. 2

    Judge the metal

    If the flashing is intact, resealing is enough. If it is corroded, short or badly lapped, it is replaced.

  3. 3

    Rebuild the joint

    New pieces are layered with the shingles, turned into the masonry or chase, and sealed.

  4. 4

    Test with water

    The area is run with a hose while someone watches from below, then photographed dry.

Chimney Flashing Repair in Snoqualmie — common questions

Is the leak always the flashing?

No. A cracked crown, a missing cap or porous brick can produce the same stain. That is why the visit begins with a full look at the chimney instead of a tube of sealant.

What separates a $330 job from a $1,500 one?

Whether the existing metal can stay. A reseal keeps it. A full replacement means lifting shingles, removing the old flashing and fitting new metal on all four sides, and roof pitch adds time.

Do I pay for the inspection as well?

Yes, $99 plus tax, and that sum comes off the flashing quote once you approve it.
