What chimney flashing repair actually involves

At the line where brick meets roofing, two materials with different movement share a joint, and sheet metal bridges it: step flashing woven into the roofing, counterflashing let into the mortar joints, and, behind a broad chimney, a small saddle called a cricket to split the flow. November tests that joint hardest. WeatherSpark's Seattle profile makes it the wettest month, with about 7.5 inches of rain spread over 16.7 wet days. Add debris from the peninsula's heavy tree cover, and water has every chance to back up behind the metal. We trace the leak first, then reseal or replace.

A reroof is the moment to get this joint right. Seattle's list of permit-exempt work (R105.2) includes recovering a roof, and also replacing roofing in kind when neither sheathing nor structure is touched, so many reroofs go ahead with no building permit and nobody reviewing the chimney joint. If a roofer is coming, ask whether new step flashing and counterflashing are in the bid, or have us handle the chimney while the roofing is open.

What's included

  • Leak tracing from the attic or the ceiling stain up to the roof
  • Removal of failed sealant and tar patches down to bare metal
  • New step flashing and counterflashing, cut into the mortar joints, where the old metal is past resealing
  • A cricket built behind a broad chimney that lacks one
  • A water test and photos once the joint is finished

Why it matters

Moss is part of the story on shaded West Seattle roofs. Oregon State University Extension treats roof moss as a given in the damp Pacific Northwest and explains that it traps soil and debris, prolongs the time roofing stays wet and may raise asphalt shingles enough for water to slip under; the lasting remedy it gives is trimming nearby trees for sunlight. Behind a chimney, a dam of moss holds water against the flashing. One caution from the same guidance: zinc sulfate should be kept off a roof with copper flashing, gutters or downspouts, since zinc attacks copper.

The stain from a flashing leak is seldom under the leak itself. Water runs down the outside of the stack inside the attic, wets framing and insulation, and surfaces as a ceiling stain a few feet away. Left alone, it rots the roof deck around the chimney and feeds mold. Tar smeared over the joint is the common quick fix; it cracks, and meanwhile it hides the metal from view. We prefer metal let into the masonry, which sheds water by its shape instead of by a bead of sealant.

How it works

What to expect with chimney flashing repair

  1. 1

    Trace

    Stains indoors are matched to a point on the roof; the uphill corners are the usual suspects.

  2. 2

    Clear

    Moss and debris around the chimney are removed by hand so the metal can be seen.

  3. 3

    Decide

    Sound metal with failed sealant is resealed; rusted, loose or tarred-over metal is replaced.

  4. 4

    Install

    Step pieces go in with the roofing courses; counterflashing is set in a cut joint and sealed.

  5. 5

    Test

    Water is run over the joint and the underside is checked before we go.

Chimney Flashing Repair — common questions

How much does chimney flashing repair cost?

We charge $375–$1,500 for flashing work. Resealing metal that is still serviceable is the lower figure; new step and counter pieces right around the stack, or a cricket built in, is the upper one.

Reseal or replace: how do you decide?

By the metal. If it is intact, firmly seated and only the sealant has failed, resealing is honest work. If it is rusted through, short, loose in the joint or buried in tar, new metal is the only repair that lasts beyond a season or two.

Should I call a roofer or a chimney company?

Roofers handle flashing every day and many do it well. A chimney company adds the masonry side: cutting the counterflashing into the joints, repairing those joints, and checking the crown and cap while up there, since leaks blamed on flashing sometimes start higher up.

Can I treat the moss around the chimney myself?

Yes, gently. OSU Extension offers soap-based products (potassium salts of fatty acids) as a noncorrosive option and warns against zinc sulfate where there is copper. Keep a pressure washer away from the chimney; it drives water under the flashing.

Does every chimney need a cricket?

It is a small peaked saddle built into the roof behind the chimney to send water around the stack instead of against it. Wide chimneys low on a steep slope benefit most. We tell you after measuring, not before.
