Our Roofing Services in Yonkers, NY
Roof Replacement and Re-Slope
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.
Roof Leak Tracing and Repair
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.
Storm Damage Restoration
The storm damage that costs real money here is seldom a covering peeled back. It is one outlet blinded by leaf litter and grit at the worst possible hour, with several inches of water standing over a top-floor ceiling and no second path out of the building.
Hail Damage on Low-Slope Roofs
Hail is not why roofs fail in this part of New York, and any company that opens with hail should be treated carefully. Severe hail reaches the lower Hudson valley occasionally rather than annually, and most of what gets sold as hail damage in this county is simply age.
Wind and Uplift Damage
A low-slope roof comes apart from its outer edge inward. Wind turns the corner at your parapet, gets beneath an unsecured lip and inflates the membrane like a sail.
Roof Inspections and Flood Tests
An inspection here starts at the drain, not at the covering. Everything else on this roof is a consequence of whether water reaches the outlet and leaves the building, so that is the first thing we test and the first line in the report you get.
Asphalt Shingle Roofs
On most of this fleet's markets, shingles are the flagship. Here they are a minority product, and saying so is more useful to you than pretending otherwise.
Metal Roofing
Metal is a real option here, but not the metal in the advertisements. The exposed-fastener corrugated panel that fills the internet needs a genuinely steep slope, and the shallow decks that dominate this city are not it.
Tile Roofing
This page mostly argues against its own product, which is the honest position in this market. Clay and concrete tile sit on a handful of Yonkers buildings, nearly all designed for it a century ago, and they are lovely.
Flat and Low-Slope Roofs
This is the main residential page on this site, and on most roofing sites it is filed under commercial. In Yonkers the flat roof is the house roof.
Roof Coatings and Sealing
Coatings are treated as a commercial afterthought almost everywhere else. Here they are a legitimate first-line residential product, because so many roofs in this city are the sort a coating was designed for, and a sound membrane at year twelve is a genuine candidate.
Roof Ventilation and Air Sealing
Balanced ventilation, the ridge-and-soffit pairing every roofing site describes, needs a ridge and a soffit. A parapet building has neither.
Skylights and Roof Hatches
On a shallow deck a skylight is not a window in a slope. It is a curb: a framed box built above the membrane, flashed as a wall on four sides, with the unit on top.
Gutters, Leaders and Roof Drains
People call us about gutters because gutter is the word everyone knows. On a parapet building there is frequently no eave to hang one on, and the thing failing is a drain, a leader or a scupper.
Fascia, Soffit and Edge Metal
On a parapet building the roof edge is not a fascia and a soffit. It is a coping cap on a masonry wall, and a gravel stop where the membrane turns.
Chimney and Parapet Flashing
Flashing is where roofs actually leak, and on a masonry building the flashing is a wall detail more than a roof detail. The membrane or the shingle stops at the wall.
Emergency Tarping and Dry-In
Tarping a flat roof the way it is done on a pitched roof creates a pond. There is no ridge to run the tarp over and nothing to shed off, so poly laid on a shallow deck fills, floats, and pushes water under the membrane it was meant to protect.
Commercial Roofing
On a site where the flat roof is already the residential product, the commercial page cannot simply be about flat roofs. What changes on a commercial or larger multifamily job is not the membrane.
Insurance Claim Help
Claims on this kind of building turn on one distinction: sudden and accidental damage is covered, gradual deterioration is not. On a low-slope roof that argument is harder than on a shingle roof, because there is no bruise pattern to photograph and the water shows up inside.
Yonkers Roof Pros is a licensed, insured roofing contractor in Yonkers, New York, working on flat and low-slope membrane, asphalt shingle, metal and slate roofs across two-family houses, walk-up apartment buildings and storefronts. We replace roofs, trace leaks, repair storm damage, rebuild drains and leaders, and install tapered insulation, coatings, skylights and edge metal.
Most roofing companies write for a house with a ridge, a soffit and a gutter at the eave. A great many buildings here have none of the three. Water leaves through a drain or a scupper inside the wall, so a covering quote that never mentions the drain is describing a different building from the one you own. That is not a stylistic difference, it is a different roof.
We start at drainage and work outward. Does the deck still carry water to its low point, is there a second path if the first one blocks, and is the insulation under the membrane dry. Those three answers set the price. Then the membrane, the perimeter metal and the shingle face are quoted separately, each with its own stated service life. We say which of the three is your actual problem before we name a single product.
What Yonkers Customers Say
Two companies quoted me a full roof on a three-family. These guys pulled the strainer, rodded the leader and reflashed the sump collar for a few hundred dollars and the ceiling has been dry through two winters. They showed me the wet core from the one bay that did need cutting out.
They separated the mansard face from the flat deck behind it and priced them apart, which no one else had done. It turned out the shingles had eight good years left and only the deck needed doing. Saved us a lot and the report was clear enough to hand straight to the board.
The hose test was the moment I understood my own roof. The low point was nowhere near where I assumed, and they chalked the line and timed it down while I watched. Tapered layout came with a drawing and the crew built exactly what was on it.
Talked us out of a coating and explained why, with meter readings and a core plug on the kitchen table. We did the drainage work first, coated the following spring, and the price for both together was still well under the replacement quote we had been sitting on.
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.
- ✓We will not put a coating over standing water or wet insulation, and we will show you the moisture readings and the core plug that made us say so.
- ✓Tapered insulation is drawn and counted before it is quoted. A re-slope is a design job with a board layout, not a line that appears on tear-off morning.
About Yonkers Roof Pros in Yonkers, NY
Yonkers Roof Pros works Yonkers and the rest of southwest Westchester, from the river blocks below Warburton up through Getty Square, Nodine Hill and Crestwood, and out into Mount Vernon, Tuckahoe, Hastings-on-Hudson and Greenburgh. Almost all of it is dense, older and built on a grade, and almost none of it looks like the suburb most roofing advice is written for.
The work splits about the way the city does. Low-slope membrane on two-family, three-family and walk-up buildings, sheet-metal and shingle work on the visible faces, and drains, leaders, scuppers and coping on nearly everything. We run our own crews on membrane rather than subcontracting it, because it is the majority of what this market needs rather than a sideline.
Here is when not to hire us. If your building sits in a covenant-governed subdivision with a steep architectural roof and no flat area at all, a shingle specialist will do that job as well as we would and probably for less. If your problem is a spalling cornice or a cracked parapet face, that belongs to a mason, and we will point you toward one rather than folding it into a roofing bid.
How It Works
- 1
Drain Test Before Product Talk
The outlet gets plugged, the low area gets a hose on it, the water line gets a chalk mark and the drain-down is timed. That is how we learn where your true low point sits and whether the roof still moves water, which every other number depends on.
- 2
Cores, Readings and a Sheet Count
Soft areas get a meter reading and a two-inch core. The plug comes back down with us and is photographed against a rule, so the number of existing layers and the state of the insulation are things you see rather than things we assert. Bad decking is counted in sheets and priced up front.
- 3
Two Systems, Two Prices
The membrane deck and the street-facing shingle or slate face are quoted as separate systems with separate service lives. One number for the whole address hides which half is failing, and that is usually the half you are paying for.
- 4
Permit, Install, Handover
We pull the city roofing permit under our Yonkers home improvement license, install to the named manufacturer specification, and hand over the permit number, the tapered layout drawing where there is one, and the warranty split by component.
Commercial and Multifamily Roofing in Yonkers and Southwest Westchester
We roof occupied buildings: apartment houses and cooperatives, storefront blocks with flats above, offices, houses of worship, warehouses and light industrial space along the Saw Mill corridor. The membrane is rarely the hard part. Scheduling around tenants, getting material onto a roof from a street that will not spare a lane, and drying in every section the same day it opens are what actually decide whether the job goes well.
- ✓TPO and EPDM at sixty and eighty mil, plus torch-applied SBS where a roof is heavily cut up
- ✓Tapered polyisocyanurate designed and quantified to a board layout, not estimated by the square
- ✓Roof drain, sump, clamping ring, strainer and interior leader itemized apart from the membrane
- ✓Through-wall scupper sleeves and coping caps set over concealed splice plates
- ✓Occupancy plan agreed with the managing agent before a price is issued: access, staging, noise, air intakes
- ✓Manufacturer field inspections scheduled into the program so the system warranty is actually earned
- ✓Twice-yearly maintenance with drains cleared before autumn leaves and again in spring
- ✓Photographed condition report with a roof plan and a reserve figure a board can budget against

Frequently Asked Questions
Does a reroof in Yonkers need a permit, and what does one cost?
Yes. The Department of Housing and Buildings issues a one and two family roofing and re-roofing installation permit, and the fee is one hundred and twenty-five dollars plus fifteen dollars per thousand dollars of estimated cost. The form asks for the roof type, the number of squares, and how many sheets of sheathing come off. It also warns that a complete re-sheathing may need a further submission before approval, which is worth knowing before you set a start date.
Does a roofer need a license in Yonkers, or is a state license enough?
There is no state license to have. New York does not license roofing contractors, so the credential that counts is local. The City of Yonkers issues a home improvement license through its Consumer Protection Bureau, and it is what the city expects a residential roofer to hold before a permit is granted. The re-roofing form carries a printed line for that number. Ask for it, then ask to see the permit for your address.
Isn't there a Westchester County home improvement license as well?
There is, but it does not apply inside this city. The county's home improvement article says in its own text that it relates only to the area of Westchester outside any city, village or part of a town that is itself regulating or licensing the home improvement business. Yonkers licenses, so the county law steps aside here. A contractor waving only a county card in Yonkers is showing you the wrong document.
My roof holds water for a day or two after rain. Is that a problem?
It is the central question on a roof like yours. The reroofing rules printed on the city permit form let a replacement keep a slope shallower than new construction would need, and let it keep a single drainage path with no emergency overflow, but only where the roof provides positive drainage. Water still standing after about two days of dry weather means those allowances no longer describe your roof, and the job becomes a re-slope.
Why does my top-floor ceiling stain in cold weather but stay dry in a rainstorm?
That pattern is condensation rather than a leak. Warm damp air from the apartments rises through light fixtures, plumbing chases and the hatch surround, meets a cold deck and gives up its moisture there. Replacing the roof does not fix it. Air sealing the ceiling plane does, and where the roof is being replaced anyway, insulation above the deck solves it permanently.
Can I just put a coating on it and buy a few more years?
Sometimes, and it is a good buy when the assembly is dry. A coating is vapor tight by design, so if the insulation underneath is wet it seals the water in and turns a repairable roof into a tear-off. We take moisture readings and cut cores before quoting one, and we will show you the numbers. The correct order is fix the drainage, dry the assembly, then coat.
