Brentwood Premium Roofing provides professional chimney flashing in Brentwood, NY for residential and commercial properties across central Suffolk County. More sound roofs get condemned over chimney flashing than over anything else we see. The covering has a decade left, water is arriving beside the stack, and somebody quotes a whole new roof. Flashing it properly keeps two or three tons on the building for a fraction of the cost.
It fails so reliably because it is the one detail nobody can rush. A chimney needs step flashing woven into each course up both sides, a base piece at the front, a saddle behind it where the stack is broad, and counterflashing let into the masonry above all of that. Six or seven separate pieces of metal, every one lapped the correct way. Caulk is not among them.
What we find on the postwar chimneys through this hamlet is usually the shortcut version: a continuous aluminum L run up the side, face-nailed, with a heavy bead of roof cement smeared across the joint. That assembly works for roughly four years. Then the cement cracks, the nails back out of the mortar, and water travels straight into the wall the chimney shares with the house.
Doing it properly means grinding a reglet into a mortar joint, folding the counterflashing into that slot, and wedging and sealing it there rather than surface-mounting it and trusting a bead to hold against a masonry face for twenty years. Where the brick is too poor to cut, we say so and price repointing first, because there is no good flashing detail into crumbling mortar.
The saddle is the other piece that gets left out. A stack measuring more than roughly two and a half feet across the slope wants a framed cricket behind it so water and leaves part around the masonry instead of piling against it. Without one you get a permanently wet line at the back and eventually a rotted deck behind a chimney that looks perfectly fine from the ground.
We flash chimneys we did not roof, and we are glad to. If your covering is otherwise serviceable this is exactly the repair worth making, and any roofer who will only quote it as part of a full replacement is telling you something about their estimate rather than about your chimney. A chimney is a detail, and details are always cheaper to put right than whole roofs are.
Our licensed and insured team brings the right materials and equipment to every job — layer counts lifted at the rake and at a valley, weighed transfer-station tickets kept in the job file, mid-weight laminated asphalt in a standard architectural profile, twenty-six gauge edge metal hemmed at the fascia line, two-inch core plugs cut through a low-slope assembly, a silicone field coat measured in wet mils — and backs the work with a written workmanship warranty. We serve Brentwood and nearby communities including Central Islip, Bay Shore, Deer Park, North Bay Shore.

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 layer counts lifted at the rake and at a valley, weighed transfer-station tickets kept in the job file, mid-weight laminated asphalt in a standard architectural profile, twenty-six gauge edge metal hemmed at the fascia line, 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 Brentwood 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 central Suffolk County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Brentwood Chooses Brentwood Premium Roofing
- ✓Every estimate opens with two numbers, the layer count and what the old covering weighs coming off, because on Long Island the removal is a sizeable share of the job
- ✓We repair more roofs than we replace and we say why, since an early tear-off is several tons of freight you paid to move off the island for no reason
- ✓We will coat a sound, dry, draining low-slope roof and argue for it, and refuse to coat a wet one or a shingle one, with the core plugs on the table behind either answer
- ✓We do not sell new tile in this hamlet. The framing on a postwar house here was never drawn for the load and the exit cost is the highest of any covering
The standards behind chimney flashing
Quality here is not a matter of opinion — it is written down. The chimney flashing work we do in Brentwood follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
