Chimney Flashing Repair

What This Service Involves

Chimney flashing is the number-one leak point on Western Washington homes because our near-constant drizzle finds every gap in aging metal and dried-out sealant. Our crews strip the compromised step and counter-flashing, correct any shingle or masonry issues underneath, and install new corrosion-resistant metal woven into the courses the way it should be. We also check the mortar reglet where counter-flashing tucks into the brick, since freeze-thaw cycles east of the Sound loosen those seats over time. The result is a watertight transition that holds up through a full Pacific Northwest winter.

Benefits

Stops the most common source of ceiling stains and attic rot in PNW homes; uses marine-grade metal that resists our salt-laden coastal air; corrects hidden shingle damage while the flashing is open; restores manufacturer warranty coverage voided by botched flashing

Our Process

1) Inspect the chimney-to-roof joint and trace the leak path; 2) Remove old step, apron, and counter-flashing and clear debris; 3) Install new interwoven flashing and re-seat counter-flashing into the mortar reglet; 4) Seal, test with water, and verify the interior is dry

What Affects the Cost

Chimney width and number of sides requiring flashing; brick versus stucco or siding surround; extent of shingle or decking damage found underneath; metal choice such as galvanized, aluminum, or copper; roof pitch and access difficulty

Best Time of Year

Address flashing repairs in late summer or early fall before the heavy October rains arrive so the joint is proven dry ahead of winter.
