What chimney flashing repair actually involves

Flashing is two layers of metal doing one job: step flashing woven into the shingles, and counter flashing let into the brick above it. Between them they bridge a joint that moves a little with every season. Sealant dries out, nails back off, and wind works at the edges; WeatherSpark puts Redmond's windier stretch at about 5.9 months, from October 17 to April 15, right on top of the rainy one. We trace the leak, lift what has failed, and either reseal sound metal or fit new flashing, with photos from the roof and, when you have attic access, from below.

Redmond's hazard annex describes wind tunnels formed by the city's hill-and-valley terrain, and steep slopes that leave some neighborhoods, Education Hill among them, more likely to feel the worst of a severe storm. It cites December 2018, when a windstorm brought gusts as high as 45 mph. On an exposed ridge, flashing is tested harder than on a sheltered street, and a look after each major blow costs less than a ceiling.

What's included

  • Leak tracing at the roof and, where reachable, in the attic
  • Resealing of sound flashing with a flexible, roof-grade sealant
  • New step and counter flashing where the metal is corroded or loose
  • Counter flashing set into the mortar joint, not just stuck to the brick face
  • Photos of the joint before and after

Why it matters

A leak at the flashing does not announce itself on the roof. It shows up as a stain on a ceiling, damp insulation or a soft spot in the roof deck, usually after water has been getting in for a while.

Water that gets past flashing wets wood, and wet framing beside a chimney rots where nobody looks. The state residential code addresses one cause directly: a chimney more than 30 inches wide, measured parallel to the ridge, that does not cross the ridgeline must have a cricket (a little saddle roof built against the uphill face), so runoff splits around the stack instead of piling against it. Wind direction is a useful clue as well. According to the Western Regional Climate Center, late fall and winter are when western Washington gets its hardest winds, and they blow chiefly from the south and southwest, so those faces of the chimney are where we look first for driven rain. Moss treatment deserves care near metal: Zinc sulfate is the wrong moss killer wherever a roof carries copper in its flashing, gutters or downspouts, Oregon State University Extension points out.

How it works

What to expect with chimney flashing repair

  1. 1

    Trace the water

    Stains show where water ends up; the roof shows where it gets in.

  2. 2

    Open it up

    Old sealant and failed metal are removed so the joint can be seen.

  3. 3

    Reseal or replace

    Sound flashing is resealed; tired flashing is replaced in both layers.

  4. 4

    Photograph the result

    You get pictures of the finished joint, since few owners ever see it in person.

Chimney Flashing Repair — common questions

What is the cost of flashing repair on a chimney?

Flashing jobs fall between $330–$1,500. Resealing metal in good condition sits at the bottom of that span; full replacement on all four sides, or adding a cricket, sits at the top.

How can I tell the leak is the flashing and not the roof?

Location and timing are the hints: staining close to the chimney that worsens in wind-driven rain points to flashing. Certainty comes from tracing it on the roof and in the attic, which is the first step of our visit.

I am getting a new roof. Should the flashing be redone then?

Yes, that is the right moment, since the shingles around the chimney are already off. Note that Duvall's permit list says re-roofing itself requires a permit there; your roofer should be handling that, and we can coordinate the chimney side.

Does my chimney need a cricket?

A cricket is a small ridge built behind the chimney to steer water around it. The state code requires one when the chimney is more than 30 inches wide along the ridge direction and sits below the ridgeline. We measure and tell you.

Is roofing tar an acceptable fix?

As an emergency patch, briefly. Tar cracks as it ages and hides the joint it covers, which makes the next leak harder to find. A lasting repair uses metal let into the mortar joint and a sealant made to flex.
