Downey Roof Pros provides professional chimney flashing in Downey, CA for residential and commercial properties across the Gateway Cities. The chimney is the biggest single interruption on most Downey houses, and it is the one most often patched rather than flashed. Tar over a joint is not a repair. It is a countdown with a fresh coat of black on it.
A correct assembly has three separate parts doing three separate jobs. Step flashings woven into each course of covering as that course is laid. A counterflashing whose top leg is cut into a reglet in the masonry, or tucked under the chase's siding, so water cannot get in behind it. And a cricket, a small framed saddle on the uphill side, on any chimney wide enough to hold back water and debris.
What we usually find is one part attempting all three. A single L-shaped piece of metal surface-mounted to the brick and sealed along its top edge, which works until the sealant shrinks, then wicks water straight down behind the flashing and into the framing below. It is quicker to install, it looks finished from the ground, and it is why we get the call. Black mastic on a chimney is a dated receipt.
Two chimney types, two approaches. Masonry needs a saw-cut reglet, a mechanically fastened and sealed counterflashing, and often crown and cap attention at the same visit. Framed chases carrying a metal B-vent need the chase cover checked first, because a flat, unsloped galvanised cover with a seam down the middle will rust through and pour water inside the chase while the roof flashing stays perfect.
Many chimneys around the basin were shortened, rebuilt or removed after the 1994 Northridge earthquake, and the roof around them was closed up during the same visit, often quickly. Where a chimney came out entirely, we still find the old opening decked and shingled over with no target patch beneath it at all. That is a hole you cannot see from anywhere and can absolutely find with a hose.
If the fireplace is unused, we will raise the option nobody else offers. Taking an unused chimney down below the roof line and closing the opening properly eliminates the penetration, the flashing, the cricket and every future repair to all three. It costs less than a full masonry rebuild and it is the only genuinely permanent fix for a chimney leak. Owners are rarely offered it because it removes future work.
Our licensed and insured team brings the right materials and equipment to every job — lead and two-piece galvanized pipe jacks, storm collars on furnace flues, self-adhered SBS target patches at the deck, counterflashing cut into a saw-kerf reglet, step and kick-out flashing at wall intersections, curbed and counterflashed equipment openings — and backs the work with a written workmanship warranty. We serve Downey and nearby communities including Norwalk, Bellflower, Paramount, Pico Rivera.

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 lead and two-piece galvanized pipe jacks, storm collars on furnace flues, self-adhered SBS target patches at the deck, counterflashing cut into a saw-kerf reglet, 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 Downey 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 Gateway Cities means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
