Glendale Roof Pros provides professional chimney flashing & spark arresters in Glendale, CA for residential and commercial properties across the Verdugo Valley. A masonry chimney hands you two problems at once. It is the most reliable leak on a Glendale roof, and it is an opening that can throw embers as readily as receive them. Both problems share the same access cost, so they belong on one visit.
The leak is nearly always the back pan. Water coming down the upper slope hits the rear of the stack and has to be turned, and on a wide chimney that means a cricket framed to divert it around both sides. Plenty of 1920s houses here never got one, so debris packs in behind the masonry and the pan rusts through from underneath. A cricket is framing work, which is why cheap bids skip it.
Correct flashing has four parts. A base pan at the front. Step flashing woven into each course up the sides, one piece per course. A back pan or a framed cricket. Counterflashing let into a reglet cut in the mortar joint and sealed. Surface-mounted counterflashing held on with a bead of sealant is a five-year repair pretending to be a permanent one. We use 26-gauge or heavier and we do not rely on caulk to hold geometry.
The arrester side is specific and it is code. A spark arrester screen with openings no larger than half an inch and no smaller than three-eighths, in corrosion-resistant material, secured to the flue rather than balanced on it. Undersized mesh clogs with creosote and chokes the draft. Oversized mesh lets burning material out over a hillside. We check the arrester on every roof we touch, whether or not the fireplace still gets used.
We look at the crown while we are up there. A cracked concrete crown lets water into the brick, and here it is sun and sulfate expansion rather than freezing that opens it up, so a spalling stack sheds material down into the pan below. Crown repair is cheap next to rebuilding a chimney shoulder.
If a chimney is decorative and unused, we will say the thing nobody selling flashing wants to say. Taking it down below the roof line and framing the opening closed permanently ends both problems for roughly what two more repairs would cost, and it removes a seismic liability at the same time. We will still flash it properly if you would rather keep it.
Our licensed and insured team brings the right materials and equipment to every job — Class A assemblies verified against the listing number, Vents listed to ASTM E2886 for ember resistance, Eighth-inch corrosion-resistant noncombustible mesh, 72-pound mineral-surfaced cap sheet, 26-gauge corrosion-resistant valley flashing, Metal bird stops and eave closures for profile tile — and backs the work with a written workmanship warranty.

Materials, equipment and how we do chimney flashing & spark arresters
The difference between chimney flashing & spark arresters that lasts and chimney flashing & spark arresters 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 assemblies verified against the listing number, Vents listed to ASTM E2886 for ember resistance, Eighth-inch corrosion-resistant noncombustible mesh, 72-pound mineral-surfaced cap sheet, 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 Glendale 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 Verdugo Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
