Chimney flashing is the metal that seals the joint where your chimney meets the roof. It is made of step flashing, counterflashing, and apron flashing working together.
The counterflashing sets into the mortar joints. When any piece rusts or pulls loose, water gets to the decking.
Step flashing repair means removing the failed metal pieces along a sidewall or chimney side and lapping new ones in with the shingles.
Step flashing can pull free as houses settle. Good flashing repair starts with checking every transition for rust, cracked sealant, and loose metal.
Chester flashing repair starts with finding the exact joint that failed, then replacing that metal instead of sealing over it.
If you are not sure what the part is called, the licensed pro we connect you with can point it out on your roof. Wider chimneys on steeper roofs may also need a cricket to divert water around them.
Chimney flashing leak repair means finding where water gets past the metal and replacing that piece, not just adding more sealant.
Stains on a wall or ceiling near the chimney almost always trace back to the flashing. Call (425) 380-0932 and book before the next storm.
Rust or dark staining below a chimney, valley, or sidewall usually means the flashing is failing, not the shingles. Trace the streak up to the flashing joint.
Sealant that is cracked or pulled away from the metal means the joint needs reflashing, not another bead. If it keeps failing in the same spot, the flashing has likely opened up.
Stains on a wall or ceiling near a chimney, valley, or sidewall almost always trace back to flashing.
Without kick-out flashing at a roof-to-wall transition, water runs into the wall instead of the gutter. It is common in Bellevue's older neighborhoods.
The pro checks the chimney, valleys, sidewalls, and pipe boots for rust, cracked sealant, and loose metal.
Each joint is judged by what the metal underneath is doing, not just how the sealant looks from the ground.
Failed step, counter, apron, or valley flashing comes out. New pieces go in, lapped with the shingles and set into the mortar joints where needed.
The pro checks sealant beads, kick-out flashing, and the chimney crown so every repaired joint sheds water.
Bellevue homes with composition shingle or cedar shake rely on the same metal at chimneys, sidewalls, and valleys to stay dry through a wet season that runs October into May. A reroof that skips that metal leaves new shingles sitting on an old failure point.
Replacing shingles alone often skips a building permit under Bellevue's roofing policy. Flashing tied into a masonry cricket or a reglet cut into brick still needs correct sequencing so counterflashing sheds water.
On Somerset and Newport Hills homes, conifer shade keeps valleys damp longer. Correct sequencing matters even more before the next wet season.
Cedar shake flashing near a chimney or valley differs from composition shingle, especially in chimney crown clearance and apron overlap. In a cedar-to-composition conversion, check that old flashing still fits the new shingle profile.
Here is roughly what flashing & chimney repair runs locally. Treat it as a guide — the property itself decides where inside the range you land.
| Written Scope | Tax Treatment | Permit Status |
|---|---|---|
| Licensed here means registered with the state, bonded, and carrying liability insurance. That status is checkable before anyone sets foot on the roof, and it matters more than a friendly sales pitch or a truck with a logo on it. | Visual check only, roof still in decent shape — no repairs, no climb on steep pitch | an estimated $245–$1805 |
| Insurance protects you two ways: it covers damage if something goes wrong during the job, and it keeps an injured worker's medical bills off your homeowner's policy. Ask to see current proof, not just a claim that coverage exists somewhere. | Tear-off, new flashing and valleys, standard shingle or shake — no structural repair | an estimated $350–$2470 |
| A bond is not the same as insurance. It's a smaller financial backstop meant to cover unfinished or defective work. Confirming both bond and insurance status takes a few minutes and avoids a much longer cleanup later. | Full reroof: complete tear-off, new decking where soft, flashing and valleys redone | an estimated $455–$3420 |
| Unlicensed work can still look competent on the surface, until a warranty claim has nowhere to go or a lien shows up after you thought the job was paid for and finished. Verification exists precisely because appearance and standing aren't the same thing. | Full tear-off, disposal, new decking as needed, no repaint or gutters | an estimated $630–$4940 |
A lower bid that separates labor from materials to shrink the taxed amount is not a discount — it is a miscalculation the state can still collect on later. The licensed pros we connect you with quote one number that already accounts for it correctly.
Flashing is thin metal, and it corrodes or works loose years before shingles wear out. Step flashing can pull free as houses settle, and counterflashing separates when mortar joints erode. In shaded areas like Bridle Trails or Somerset, trapped moisture speeds that breakdown.
Resealing adds fresh sealant over an existing joint, a short-term fix for a small gap. Reflashing removes the old metal and replaces the step, counter, or apron flashing itself. The licensed pro we connect you with can tell you which one your roof needs.
Often, yes. Tearing off shingles around a chimney usually disturbs the counterflashing enough that it should be reset or replaced. It is also the time to check the chimney crown and mortar joints for cracks.
A chimney cricket is a small peaked structure on the uphill side of a chimney that diverts water and debris around it. Wider chimneys on steeper roofs, common near Cougar Mountain and Lakemont, are the most likely to need one. It depends on chimney width and roof pitch.
Kick-out flashing sits where a roof-to-wall transition meets a gutter and sends water into the gutter instead of behind the siding. Missing kick-out flashing is a common cause of hidden wall damage in older Bellevue homes. It is easy to overlook during a reroof.
Most homeowners pay an estimated $350–$1900 per job for flashing & chimney repair in Bellevue. Two things move that figure more than anything else: the pitch, and how much of the decking underneath turns out to be sound. Quotes are given after a look at the roof, not over the phone.
A roof problem in one part of town rarely matches a roof problem somewhere else nearby, even a short drive off Bellevue Way or across from a park like Kelsey Creek. Slope, shade, and age all change what a roof needs. The licensed pros we connect you with look at your actual roof before naming a cause or a fix.
Winter in Bellevue leaves marks a homeowner can actually find: lifted moss, loose flashing, a stained ceiling patch. This walkaround covers what to check from the ground and the attic, and why spring is the practical window to line up any follow-up work before summer books solid.

Bellevue roofs rarely fail from one storm. They wear out from months of damp shade, clogged valleys, and weak flashing details that never get a real chance to dry between rains.
