Yonkers Roof Pros provides professional roof leak tracing and repair in Yonkers, NY for residential and commercial properties across southwest Westchester. A leak on a low-slope deck almost never shows under the hole. Water travels between membrane and insulation, finds a fastener or a lap, and drops through a ceiling two rooms from where it entered. Chasing the stain is how owners buy roofs they never needed.
So we work the drainage path first. A blocked strainer, a cracked clamping ring, a leader joint rusted through inside a chase, a scupper whose sleeve has parted from the masonry: every one of those puts water in the building with the covering still sound. Every one is also cheap to fix, which is precisely why the covering gets blamed instead. Ask any roofer who has quoted you a replacement whether they pulled the strainer first.
Then the field itself. We probe hot-air-welded lap seams with a blunt tester, sound the deck for soft insulation underfoot, and cut a two-inch core wherever the readings and the surface disagree. A core answers the only question that matters at that stage: is the wet insulation one bay wide or the whole roof. Patch and re-slope part company there. The plug goes back with a patch, so the test never becomes the next leak.
Walls and curbs come third, because on a parapet building the leak is often not on the roof at all. Open coping joints, a spalled masonry face above the counterflashing, a condenser curb with no cricket behind it. Each gets photographed with a note tying it to the ceiling stain beneath, so somebody who never went up can still follow the argument.
On the street-facing slope the method changes entirely. There we lift courses, read the nailing line and the underlayment lap, and check whether the step flashing runs behind the siding or was slipped over it and sealed. Two roofs on one address, two separate vocabularies of failure, and a report that refuses to blur them together. Sealant run over a step flashing is a diagnosis rather than a repair, and it is usually the wrong one.
What you receive is a written finding with the repair priced by component: drain assembly, seam work, curb flashing, coping joints. If the true answer is that your membrane has three winters left and the leak is a twelve-dollar strainer basket, that is what the report says and that is the invoice we send. You are not billed for the assessment either way.
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.

Materials, equipment and how we do roof leak tracing and repair
The difference between roof leak tracing and repair that lasts and roof leak tracing and repair that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with 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, 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 Yonkers 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 southwest Westchester means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

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.
