Chimney Flashing Repair in Wallingford, Seattle

The range for chimney flashing repair in Wallingford is $375 to $1,495, and the two figures describe two different jobs. $375 is a repair: the existing metal is sound, and what failed is the seal where it enters the brick or a single corner. $1,495 is a renewal: every piece comes out and new base, step and counter-flashing go in, with a saddle on the uphill side if the chimney is wide. Chimneys that straddle the ridge, slate or tile roofs, and three-story access push a job toward the higher number.

Why Wallingford homes need chimney flashing repair

Wallingford's 1920s growth added apartment buildings to the bungalow streets: the Lisa Carol Apartments went up on Corliss Avenue N in 1926 and the Burke Avenue Apartments in 1928. The 2022 National Register listing for the Wallingford-Meridian Streetcar Historic District counts 66 multifamily buildings beside its 570 houses. With houses and apartment buildings side by side, roofs differ from one address to the next. The flashing detail changes with the roof, and a method that suits a chimney rising through a shingled gable is wrong for one standing at the edge of a flat roof.

Four inches in a day beside the lake: the storm a Wallingford roof joint must pass

Flashing is not tested by average weather. It is tested by the worst day in a decade. On January 18, 1986 Portage Bay's gauge, down by Lake Union, measured 4.22 inches of rain in 24 hours. Windier months in Seattle run from mid-October to late April by WeatherSpark's reckoning, and December has the highest mean wind speed.

On a day like that a roof plane sheds a continuous sheet of water, and a chimney stands in its path. Everything arriving from uphill has to be turned around the stack by metal alone. Step flashing does it at the sides, a saddle behind, an apron in front, and the counter-flashing keeps the upper edges covered. One missing or unsealed piece is enough. This is why our repair ends with a hose test that imitates a downpour, not a drizzle, with someone in the attic watching the back of the joint.

Your chimney flashing repair in Wallingford: what's included

Every chimney flashing repair we do in Wallingford includes:

  • Controlled water test, lowest point first, to locate the entry
  • Shingles beside the chimney lifted to expose the step flashing
  • Reglet cut into the mortar joint for the counter-flashing
  • New metal lapped in the direction water runs, corners soldered or folded
  • Saddle framed and flashed behind chimneys that need one
  • Attic-side check during a final hose test

Signs you need chimney flashing repair in Wallingford

  • Ceiling damage that appears only when rain comes with wind
  • Wet insulation or dark sheathing beside the chimney in the attic
  • Flashing that lifts when pressed, or flaps in a breeze
  • A bead of caulk along the brick, cracked and pulling away
  • A pile of needles and moss wedged behind the stack

Why Wallingford homes need it

Seattle does not ask for a permit to replace the roofing on a house or duplex, so long as nobody alters the envelope and the fresh covering matches or betters its predecessor. The consequence is that chimney flashing is renewed, or not, at the roofer's discretion. The residential code does set one requirement at this joint: a stack that measures over 30 inches in the ridge direction must, per R1003.20, have a cricket on its upslope face. Without one, the uphill face of a wide stack becomes a dam, and leaves, moss and standing water do the rest.

  1. 1

    Water test

    The joint is wetted in stages from the bottom up until the leak shows inside.

  2. 2

    Open the roof edge

    Roofing next to the chimney is lifted carefully so the hidden metal can be seen.

  3. 3

    Repair or renew

    Sound pieces are resealed in a proper groove; corroded or missing ones are replaced as a set.

  4. 4

    Retest and close

    The hose goes back on, the attic stays dry, and the shingles are relaid.

Chimney Flashing Repair in Wallingford — common questions

The roof is new. Why would the chimney leak now?

Because a reroof may reuse old chimney flashing or replace it with sealant. No permit inspection is triggered by a like-for-like reroof on a house, so the joint may never have been looked at by a second person.

Copper, lead or steel?

We match what the roof and the house call for and say why. One caution, which we owe to the extension service at Oregon State: a zinc sulfate moss killer eats copper. Keep them away from a roof whose flashing is copper.

Is there a fee for the water test?

It is carried out during a paid inspection, $99 plus tax for the chimney tested. That fee does not stack with the repair: accept the flashing quote and it is taken off.
