Yonkers Roof Replacement and Re-Slope — Residential & Commercial

Yonkers Roof Pros provides professional roof replacement and re-slope in Yonkers, NY for residential and commercial properties across southwest Westchester. Most Yonkers addresses carry two roofs. There is a membrane deck behind the parapet that nobody sees, and a shingle or slate face along the street that everybody does. They finish on separate schedules, and one number for the building hides which one is actually done.

Before we name a product we settle whether the deck still carries water to its outlet. That word carries legal weight as well as physical weight. The reroofing section printed on the city's own one and two family permit form waives the quarter-inch design slope, and waives adding emergency overflow drainage, but writes both waivers only for roofs that provide positive drainage. Standing water withdraws them. We test it with a hose, not by eye.

When the water stops moving, replacement is no longer a covering job. It becomes a re-slope: tapered polyisocyanurate laid out board by board to a drawn plan, a rebuilt sump under the drain, and usually a second outlet cut through the parapet so one blocked strainer cannot flood a top-floor apartment. We draw that and count the boards before quoting it. The drawing goes into the permit set with the application.

The deck below decides the rest. The permit form asks how many sheets of sheathing are being replaced, and warns that a complete re-sheathing may need a further submission before approval, which is a calendar fact as much as a price. We cut a test opening at the low corner and one at a wall, then put the sheet count on the estimate.

The street face is quoted on its own. Where the visible slope is architectural shingle it gets a separate tear-off, its own underlayment and its own stated service life, because a twenty-five-year covering sitting above a fifteen-year membrane is a real mismatch and you deserve to hear about it beforehand. Sometimes the right move is to do one and leave the other. Both dates go on the warranty, so nobody has to argue about them in year fourteen.

We will say plainly when a full replacement is premature. A sound two-ply modified bitumen deck with wet insulation in one bay is a cut-out, a dry-down and a drain rebuild, not a new roof. Where the full job is right, you get the permit number, the tapered layout drawing, and a warranty listing field, edge metal and drain assembly apart.

Our licensed and insured team brings the right materials and equipment to every job — cast-iron drain bowls with replacement clamping rings, tapered polyisocyanurate laid to a quarter-inch board layout, lead-lined through-wall scupper sleeves, torch-applied SBS cap sheet turned up the parapet, gravel-stop edge metal set in two courses of flashing cement, sheet-metal coping caps with concealed splice plates — and backs the work with a written workmanship warranty. We serve Yonkers and nearby communities including Mount Vernon, Bronxville, Tuckahoe, Eastchester.

What We Handle

Why Yonkers Chooses Yonkers Roof Pros

• ✓We settle one question before any other: does this roof still drain. The city's own re-roofing permit hangs two code allowances on that word, and your price hangs on it too.
• ✓A hose test on the low corner with the chalk line and the drain-down time written onto the estimate, rather than a slope guessed at from the sidewalk.
• ✓The drain bowl, clamping ring, strainer and the leader inside the wall chase are itemized apart from the membrane, because they fail on a completely different clock.
• ✓Where the street face is shingle and the deck behind it is membrane, you get two systems, two prices and two service lives, never one figure for the address.
