Free Chimney Chase Cover Replacement Quote in Issaquah
We'll confirm a time by phone or text.
Issaquah’s newer neighborhoods, the Highlands, Talus, and the plats along the I-90 corridor, were mostly built with factory-built fireplaces in wood-framed chases, and the metal cover on top of that chase is the part that fails first. Builder-installed covers were commonly flat galvanized steel. Flat means water pools, galvanized means it rusts, and under a canopy of firs the cover grows moss that holds the water in place. The first sign is usually rust streaks running down the chase siding; the second is a stain on the ceiling near the fireplace.
We replace the failed cover with a stainless or heavy-gauge cover that is cross-broken so water drains to the edges, with a drip edge and a new storm collar sealed around the pipe. While the old cover is off we check the pipe joints and the top of the chase framing for rot, and we tell you what we find before any extra work. Chase cover replacement starts at $299. The quote is free, we price match plus 10-25% off any written quote, and because Issaquah is minutes from Renton, same-day service is often available for the measuring visit. If you are not happy, we are not done.

Issaquah Conditions
Why this happens in Issaquah
A chase cover in Issaquah sits in shade for much of the day, and that changes how fast it fails. Regional guidance notes that Western Washington moss grows fastest from October through April on tree-shaded surfaces that dry slowly, and the extension handbooks describe moss thriving on plentiful water and low-to-moderate light. Add the wet season itself, about 29.65 inches of rain from October to March, roughly 73% of the annual total, and a flat galvanized cover on a shaded Issaquah roof typically sits under standing water and moss for months at a time. Rust follows.
Hillside construction adds a second problem. On many Highlands and Talus homes the chase is on the tall downhill wall, so the cover is rarely seen from the ground or even from the rest of the roof. A cover that has been rusting for years typically goes unnoticed until water reaches the ceiling. Sea-Tac records roughly 150-156 days of measurable precipitation a year, so there is no shortage of water to find the hole.
How It Works
Our chimney chase cover replacement process
Measure the chase
We measure the chase, the flue pipe diameter and position, and the skirt height so the new cover fits without gaps.
Fabricate the cover
The replacement is made from stainless steel or aluminum with a cross-break, raised collar, and a drip-edge skirt over the siding.
Remove the old cover
The rusted lid comes off and we inspect and dry out the top plate. Minor wood damage is addressed before the new cover goes on.
Set and fasten
The new cover is fastened through the skirt into the sides of the chase, never through the top, and the collar is sealed to the flue pipe with high-temperature sealant.
Cap and check
We reinstall or replace the flue cap, confirm the storm collar is sealed, and photograph the finished top for you.

Chimney Chase Cover Replacement in Issaquah — FAQ
My Issaquah chase cover has moss on it but no visible rust. Should I replace it?
Not necessarily. We clean the moss off during a free quote visit and look at the metal underneath. If the cover is sound and sloped, we leave it and tell you so. If it is flat galvanized with pitting or rust spots under the moss, replacement starting at $299 is cheaper than the framing repair a failed cover leads to.
How do you get to a cover on a two-story chase in the Highlands?
With the right ladders and fall protection, which we bring. You never need to go on the roof or up a ladder yourself. We measure the chase on the first visit, fabricate the cover, and install it on a second short visit, usually within days since Issaquah is a quick drive from our Renton office.
How soon can you do chimney chase cover replacement in Issaquah?
We confirm a time by phone or text after you request a quote; same-day service is often available for urgent problems in Issaquah and the rest of King County.
