Richmond Roofing Pros provides professional chimney & wall flashing in Richmond, CA for residential and commercial properties across the North East Bay. A chimney is flashed correctly with two pieces of metal, not with sealant. Step flashing woven into the shingle courses on each side, and counterflashing let into a cut reglet in the mortar joint and folded down over the top of it. Caulk is the thing that fails.
On the older Richmond stock we find the other version constantly: a bead of black mastic smeared where the brick meets the roof, refreshed by somebody every few years until it splits in the same place each winter. It works while it stays soft. Then a front pushes water into the joint from the upslope side and the ceiling below the chimney stains. Mastic is a maintenance habit dressed up as a repair. It never stops needing you.
The upslope side is the one that matters here. Water and wind arrive together and pile against the back of the chimney, so anything wider than about thirty inches gets a cricket: a small framed saddle, sheathed and flashed, that splits the flow around both sides. Without one, the back of a chimney is a dam with a roof behind it. A cricket is framing and sheathing work, so it belongs in the scope from the start.
Material choice matters. We flash in lead-coated copper or heavy malleable aluminum, both of which can be dressed into an irregular mortar line, and we grind a proper reglet rather than relying on surface-mounted trim. Where a chimney has been stuccoed over, the counterflashing goes behind the weather-resistive barrier, which means opening a little of the wall. Aluminum against masonry wants isolating; lead-coated copper does not care. That choice is worth making deliberately.
Sidewall flashing gets the same treatment wherever a roof plane meets a two-story wall, which is common on the additions and second-story pop-outs around here. Step flashing behind the siding, kick-out flashing at the bottom of the run so water is thrown clear into the gutter, and no reliance on the wall covering to shed any of it. A missing kick-out is the reason so much sheathing rots behind a two-story wall.
We also look at what sits above the flashing while we are up there. A cracked crown, an open mortar joint or a missing rain cap puts water inside the flue and down the inside of the chase, and that shows on the same ceiling as a flashing leak. Fixing only the metal would leave you with the stain. So we look at the masonry as well as the metal, and say which one is leaking.
Our licensed and insured team brings the right materials and equipment to every job — ASTM D7158 Class H wind ratings, ASTM D3161 Class F sealed-shingle testing, factory-adhesive starter strip at rakes and eaves, cap-fastened synthetic underlayment at six-inch perimeter spacing, 24-gauge standing seam on concealed clips, Kynar 500 PVDF finish over Galvalume — and backs the work with a written workmanship warranty. We serve Richmond and nearby communities including San Pablo, El Cerrito, Pinole, Hercules.

Materials, equipment and how we do chimney & wall flashing
The difference between chimney & wall flashing that lasts and chimney & wall flashing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with ASTM D7158 Class H wind ratings, ASTM D3161 Class F sealed-shingle testing, factory-adhesive starter strip at rakes and eaves, cap-fastened synthetic underlayment at six-inch perimeter spacing, 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 Richmond 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 North East Bay means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
