Brentwood Premium Roofing provides professional flat and low-slope roofing in Brentwood, NY for residential and commercial properties across central Suffolk County. Almost every low-slope roof in Brentwood is an addition. A rear extension, a converted garage, a porch, a dormer deck tied into the main gable. They are small, they are old, and they are where the choice between recovering and stripping is worth real money on this island.
A saturated low-slope assembly is the heaviest thing a small house can produce. Old built-up roofing, wet fiberboard, a couple of tar-and-gravel recoats and thirty years of absorbed water can weigh several times what the same area of asphalt shingle weighs. All of it must be weighed and hauled off Long Island, which is exactly why we refuse to guess at whether it is wet.
So we cut cores. A two-inch plug taken through the assembly on each field area shows the layer count, the insulation type and thickness, and whether the boards are dry. It takes a quarter of an hour, it is patched before we leave, and it converts the largest unknown on the job into a fact. An opinion formed from the ground about a low-slope roof is worth nothing at all.
If the cores come back dry and the deck is sound, a recover is very often correct here and we will recommend it. Sixty-mil single-ply over a half-inch cover board, fully adhered or mechanically fastened to suit the deck, leaves the existing assembly in place and sends nothing to the scale. It is cheaper, and it is the smaller environmental bill by a wide margin.
If the cores come back wet, none of that applies and we will say so with the plugs on your kitchen table. Sealing water into an assembly does not stop it working on the deck underneath, and a recover over wet insulation simply makes the eventual removal heavier, later and dearer. That is the one situation where the disposal argument points squarely at stripping.
Details are where these roofs actually leak. The transition where the low slope meets the shingled main roof, the counterflashing at the house wall, the edge metal, and the drain or scupper if there is one. We price those as named items with a gauge and a method, never as a lump sum hiding under the word flashing. Naming a component is how you learn whether the person quoting has been on the roof at all.
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 flat and low-slope roofing
The difference between flat and low-slope roofing that lasts and flat and low-slope roofing 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
