Kent Roof Pros provides professional chimney flashing in Kent, WA for residential and commercial properties across the Green River valley and south King County. Of everything standing on a roof, a masonry chimney is the hardest to keep dry, and in this region it is also the element most likely to be damaged by an earthquake. Both point at one question: is yours still doing a job worth paying for.
When the Nisqually earthquake shook the Puget lowland in 2001, damaged chimneys were the signature residential loss across the region. Unreinforced brick stacks standing above a roof line have very little holding them together in shaking, and a great many houses here still have one serving an appliance that was converted to gas or abandoned years ago. A great many of those stacks are now purely decorative.
So the recommendation we give more often than any other on this page is removal. Dropping a disused stack to below the roof plane, then framing and decking the opening and roofing straight over it, costs less than rebuilding the crown and reflashing it properly, ends the leak permanently, and removes a known hazard from above your bedroom. Homeowners are usually surprised that the cheaper option is also the safer one.
Where the chimney stays, it gets flashed the way it should have been the first time. Step flashing laced in course by course on both sides, a head flashing formed across the back, and the counterflashing tucked into a reglet sawn in the mortar joint rather than surface-glued to the brick and sealed with a bead that has perhaps four years in it. Surface-mounted counterflashing is a short-lived detail sold as a permanent one.
Any stack wider than about two feet gets a cricket framed on the uphill side. Without one, the flat back wall of the chimney is a dam holding needles, grit and water against the masonry, and in a climate where that debris stays wet the mortar joints go first and the flashing gets blamed. The cricket is framed, sheathed and flashed as part of the roof rather than added afterwards.
We also look at the crown and the cap, since a split crown feeds water into the brick from above, and no flashing detail ever built will fix a chimney drinking through its own top. A cast crown with a drip edge and an overhang, plus a stainless cap, is the small money that keeps the big money working. Water gets into masonry from above more often than from the side.
Our licensed and insured team brings the right materials and equipment to every job — Class A laminated asphalt shingles set on a six-nail pattern, self-adhered ice and water membrane at eaves, valleys and penetrations, tapered polyisocyanurate laid to a re-surveyed drainage plane, two-ply SBS modified bitumen at porch and addition tie-ins, concealed-clip standing seam panels over high-temperature underlayment, sheathing re-planed with ripped cedar shims before underlayment goes down — and backs the work with a written workmanship warranty. We serve Kent and nearby communities including Auburn, Federal Way, Renton, Tukwila.

Materials, equipment and how we do chimney flashing
The difference between chimney flashing that lasts and chimney flashing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with Class A laminated asphalt shingles set on a six-nail pattern, self-adhered ice and water membrane at eaves, valleys and penetrations, tapered polyisocyanurate laid to a re-surveyed drainage plane, two-ply SBS modified bitumen at porch and addition tie-ins, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Kent job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in the Green River valley and south King County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Kent Chooses Kent Roof Pros
- ✓We establish which ground your address sits on, valley fill or glacial hillside, before a specification is written, because the two need different roofs
- ✓Ridge and eave offsets are measured and recorded on the first visit and again at completion, so the file shows whether anything is still moving
- ✓We decline coating work where the ponding traces back to building settlement, and we put the reason in writing rather than taking the job quietly
- ✓Nobody here will write a hail claim on a Puget lowland roof. We chalk a test square, count the hits and give you the number even when it kills the job
