Flashing is the metal that bridges the gap between the roof and the chimney. The roof and the masonry move differently as they heat, cool and settle, and the flashing has to cover that joint for decades. When it fails, water runs down the outside of the chimney into the ceiling, and people often blame the roof.
Every chimney flashing repair we do in Issaquah includes:

Book nowWhat we find on Issaquah roofs is often a patch rather than a repair: a bead of caulk or roofing tar smeared over the joint where metal meets brick. It holds for a season and then cracks. Proper counterflashing is cut into a mortar joint and folded over the step flashing, so it keeps shedding water even as the roof and chimney move.
We check the flashing from the roof and the framing from the attic to confirm the water is coming in at the chimney, and not through the cap or the brick.
Tar and caulk come off so the metal underneath can be judged. Sound pieces stay; bent or corroded ones are replaced.
Step flashing is woven into the shingle courses and counterflashing is set into a cut mortar joint, overlapping so water always runs outward.
The joint is sealed, the roof is cleaned up, and you receive photos of each side of the chimney.

Water piles up on the uphill side of a chimney, because the roof channels everything toward it. The Washington State Residential Code deals with this directly: when a chimney is more than 30 inches wide parallel to the ridge, a cricket, a small peaked diverter, is required behind it, flashed and counterflashed like the rest of the joint.
In a town where average rainfall outpaces nearby lakeshore Bellevue, that rule earns its keep. The Chimney Safety Institute of America also lists sound flashing as one of the basic defenses against water damage in masonry chimneys, so we check the uphill side first on every visit.
Issaquah is a city nestled against the Issaquah Alps, with a historic downtown plus large newer developments in the highlands. We work every part of it — Gilman, Issaquah Highlands, Squak Valley included.
