Chimney Flashing Repair
Flashing seals the joint between your chimney and roof — when it fails, water runs straight into your ceilings and walls.

Surprisingly, the majority of 'chimney leaks' aren't actually originating from the chimney itself, but rather from compromised flashing where the chimney meets the roofline. When this vital metal-and-sealant joint corrodes, lifts, or was poorly installed, water gains a direct pathway into your ceilings and walls. We meticulously pinpoint the true source of the leak, then either reseal existing sound flashing or replace damaged sections, ensuring it's properly integrated back into your roof for a completely watertight seal.
High winds characteristic of the Pacific Northwest tend to lift and loosen flashing more rapidly, causing waterfront homes to experience leaks sooner.

What's included
Most instances of 'chimney leaks' actually stem from failing flashing at the roofline, not the chimney structure itself — and the longer water infiltrates, the more extensive the interior damage becomes.
How it works
We trace water staining back to its actual entry point.
Sound flashing is resealed; corroded or lifted flashing is replaced.
Step- and counter-flashing are integrated back into the roof.
Photos document a watertight roof-to-chimney joint.
Local & accountable
Why it matters
The vast majority of 'chimney leaks' are misidentified; they originate not from the chimney structure, but from the flashing—the crucial metal-and-sealant interface where the chimney meets the roof. When this joint corrodes, lifts, or was improperly installed, water flows unimpeded into your ceilings, walls, and structural framing. There, it can rot wood and promote mold growth, often remaining undetected for extended periods. Addressing flashing issues promptly can prevent an affordable reseal from escalating into a far more expensive framing and drywall repair.
If any of these sound familiar, it's worth a free inspection:
See the difference
The before shows rusted, lifted flashing at the seam where chimney meets roof — the most common culprit behind that stubborn ceiling stain. The after is new step and counter-flashing, layered, lapped and sealed properly. Real flashing work is a metal detail built in layers, not a bead of caulk smeared over the problem, and it's what keeps the joint dry through a wet-season storm.
Rusted, weeping flashing swapped for fresh metal, sealed where chimney meets roofline.
Representative example of a typical chimney flashing repair — not a specific customer job. We add photos of our own completed the Eastside projects as we finish them.
A job that comes up every wet season: a lakeside home where the same ceiling stain reappears near the chimney after each heavy rain. Nine times out of ten on an exposed roof, the culprit is the flashing — rusted, lifted, or held together by old caulk that's finally let go. We'd typically strip the failed metal and build proper step and counter-flashing, lapped and sealed where chimney meets roof. The usual result is a joint that stays dry through the next storm off the lake — and a stain that finally stops coming back.
