What is included
What a Full Replacement Includes
Every commercial roof replacement we install includes the items below. Add-ons like skylight replacement, HVAC curb work, or solar-ready mounting are quoted separately so you can see the cost of each.
Full Tear-Off to Deck
We remove every layer of the old roof down to the structural deck. No overlays, no trapped moisture. The deck gets inspected and any rotting decking is replaced before the new assembly goes down.
New Underlayment and Insulation
Ice and water shield at eaves, roofing felt or synthetic underlayment on pitched sections, and rigid insulation on flat roofs. Insulation thickness is spec'd to current energy code for your building type.
Warrantied Membrane System
TPO, EPDM, PVC, modified bitumen, or metal, installed to manufacturer spec. Seams are welded or spliced and rolled with a seam roller. You get the manufacturer system warranty in your name.
New Flashing and Edge Metal
Every penetration, curb, wall, and edge gets new flashing. We install new drip edge, pipe boots, and counterflashing. This is where most roof leaks start, so we do not reuse old metal.
Ventilation and Drainage
Ridge vent on pitched roofs, new drains and scuppers on flat roofs, and corrected slope where ponding water has been an issue. Water leaves the roof instead of sitting on it.
Cleanup and Warranty Handoff
Magnet sweep for fasteners, full debris haul-away, and a walkthrough where we hand you the manufacturer warranty and our workmanship warranty. Final inspection takes about 30 minutes.

Service overview
Commercial Roof Replacement Freeport NY Explained
Commercial roof replacement Freeport NY is the full tear-off and rebuild of a low-slope or steep-slope roof system on a business, multi-family, or mixed-use building. It is needed when repairs no longer hold, when ponding water or flashing failure has spread, or when the existing membrane is past its manufacturer-rated life. We strip the old layers down to the deck, inspect for rotting decking, replace what is soft, then install new underlayment, insulation, and a finished membrane with new flashing and edge metal.
Freeport buildings take a beating. Salt air off the bay corrodes fasteners and metal edge, nor'easters drive rain sideways into seams, and freeze-thaw cycles in January open gaps that were tight in October. If you have been searching for commercial roof replacement near me Freeport and getting quotes that skip the deck inspection, that is a red flag. We quote the whole job, not the part that shows.
- Stop Chasing Leaks — Once water is traveling under the membrane, every patch just moves the leak. A full replacement removes the saturated insulation and wet decking so the new system starts dry. Most customers see leak calls drop to zero in the first year after a commercial roof replacement Freeport project.
- Lower Energy Bills — White TPO and PVC membranes reflect sunlight instead of absorbing it. On a 10,000 sq ft flat roof, that can cut cooling load noticeably through July and August. We pair reflective membrane with the right insulation thickness to hit current energy code.
- Protect Tenant Relationships — Ceiling stains and dripping lights push tenants to look elsewhere. A new roof removes the reason for complaints and gives you a documented system with a manufacturer warranty you can show at lease renewal.
- Raise Property Value — A roof with 20-plus years of remaining life is a line item buyers and appraisers can verify. Sellers who complete a full commercial roof replacement Freeport New York before listing avoid price cuts and inspection negotiations tied to roof condition.
- Core Cuts, Not Guesses — We cut physical samples through every layer before quoting. You see the photos. If the deck is sound and only the top ply is gone, we tell you. If it is saturated, we show you why a full tear-off is the only honest option.
- Manufacturer-Backed Warranties — Our GAF, Firestone, and Carlisle SynTec installations come with manufacturer system warranties plus our own workmanship coverage. That matters when you sell the building or file an insurance claim after a storm.
- Coastal-Grade Detailing — Salt air eats cheap fasteners. We spec corrosion-resistant plates, stainless edge metal where it counts, and welded seams on TPO and PVC. It costs a little more up front and saves a full re-roof later.
- Clean Sites, Quiet Crews — We protect landscaping, keep the dumpster out of tenant parking when possible, and sweep for nails daily. Most commercial roof replacement services Freeport businesses hire leave a mess. We do not.
The service timeline
How Our Replacement Process Works
Inspection and Core Cuts
We walk the roof, cut core samples through each layer, and check the deck from above and below. You get a written scope with photos showing exactly what is wet, what is sound, and what the new assembly will be. This usually takes 60 to 90 minutes on a typical 5,000 sq ft roof.
Tear-Off and Deck Repair
Crews remove the old membrane, insulation, and flashing down to the deck. We set a dumpster and use plywood runners to protect your lot. Any rotting decking gets cut out and replaced with like-kind material before we go further. Most tear-offs run two to four days.
New Assembly Install
We install ice and water shield at the eaves, new underlayment or cover board, then the membrane. TPO and EPDM seams get hot-air welded or spliced, then rolled with a seam roller. Fasteners are set with a roofing nail gun on steep-slope sections and plates on flat sections.
Flashing and Detail Work
New roof flashing goes in at every penetration, curb, and wall. We replace ridge vent on pitched roofs and install new edge metal, drip edge, and pipe boots. This is the stage that decides whether the roof leaks in year three or year twenty.
Final Inspection and Cleanup
We run a water test on suspect areas, sweep the roof with a magnet for stray fasteners, and haul away every scrap. You get the manufacturer warranty paperwork and our workmanship warranty the same day. Final walkthrough takes about 30 minutes.
Tools and methods01 02 03 04 05 06 07 08 09 10 11
Tools and Methods We Use
Roofing nail gun
Drives shingles and underlayment fasteners at consistent depth and spacing on pitched sections. Faster and more accurate than hand-nailing, which matters on larger roofs.
Seam roller
Presses welded TPO and PVC seams flat after hot-air welding. A properly rolled seam is the difference between a watertight membrane and a slow leak at every lap.
Roofing safety harness and ladder stabilizer
Keeps crews tied off and ladders stable on steep pitches and multi-story buildings. Non-negotiable on every commercial job we run.
Pry bar and shingle cutter
Removes old shingles, flashing, and nails during tear-off without damaging the deck. Clean removal makes deck inspection and repair faster.
Chalk line and utility knife
Layout and cut membrane, underlayment, and insulation to exact dimensions. Straight lines mean tight laps and fewer seam failures.
Air compressor
Powers pneumatic nailers and cleanup tools on site. Keeps the install moving without waiting on batteries or hand tools.
Core-cut inspection
We cut 2-inch samples through every layer of the existing roof to measure thickness, identify materials, and check for wet insulation. This is how we know whether a repair or replacement is the honest answer.
Hot-air welded seams
TPO and PVC membranes are joined with hot-air welding, then rolled with a seam roller. Welded seams are stronger than the membrane itself when done to manufacturer spec.
Manufacturer system installation
We install complete systems from GAF, Owens Corning, CertainTeed, Firestone, Carlisle SynTec, and Versico. Using one manufacturer's full assembly is what qualifies the roof for a system warranty.
Wind-uplift fastening patterns
Fastener spacing and plate patterns are set to meet current wind-uplift requirements for coastal Nassau County. This is code, not an upgrade, and we do not cut corners on it.
Water testing before sign-off
We run water tests on suspect areas and around new flashing before the final walkthrough. If something leaks, we find it before you do.
Where this service helps
When to Schedule a Replacement
A 6,000 sq ft retail strip in Freeport with a 22-year-old modified bitumen roof that leaks every spring.
We cut cores, confirm the insulation is saturated, and replace the system with white TPO over new insulation. Tear-off and install take about seven working days. Leak calls stop, cooling load drops in summer, and the owner has a 20-year manufacturer warranty to show at lease renewal.
A waterfront restaurant near Woodcleft Avenue with grease exposure and a failing EPDM roof.
We spec PVC membrane instead of TPO because of the kitchen grease, install new curb flashing around exhaust fans, and correct the slope toward new drains. Grease no longer degrades the membrane, ponding stops, and the roof passes health inspection without issues.
A multi-family building in Baldwin with three layers of shingles and rotting decking around the chimney.
Full tear-off to the deck, replace rotted sheathing, install ice and water shield, new underlayment, and architectural shingles with new flashing at the chimney and vents. Ice dams stop forming at the eaves, the chimney leak is gone, and the building appraises higher at refinance.
A warehouse in Roosevelt with hail-bruised TPO and wind-lifted seams after a summer storm.
We document the damage for the insurance claim, tear off the damaged membrane, and install a new TPO system with upgraded fastening to meet current wind-uplift code. Insurance covers most of the replacement, and the new assembly is rated for the wind loads this part of Nassau County actually sees.
Local execution
How Replacement Runs in Freeport
Freeport sits on the South Shore, which means salt air, nor'easters, and freeze-thaw cycles that punish roofs. Metal fasteners corrode faster here than they do 20 miles inland, so we spec corrosion-resistant plates and stainless edge metal on coastal jobs. Winter storms drive rain sideways into seams, and January freeze-thaw opens gaps that were tight in October. We schedule most commercial roof replacement Freeport New York projects between April and October, but we run winter installs when a roof cannot wait. Nassau County code requires permits for full tear-offs, and we pull them. If you are comparing commercial roof replacement cost Freeport NY quotes, ask whether the contractor is pulling permits and cutting cores. If they are not, the quote is not comparable.
Nautical Mile / Woodcleft Avenue
Restaurants and waterfront commercial buildings with grease exposure and salt air. PVC membrane and corrosion-resistant fasteners are the right call here.
Downtown Freeport
Mixed-use buildings with retail below and apartments above. We schedule tear-off around business hours and keep the dumpster off the sidewalk when possible.
Freeport Harbor area
Marine-adjacent buildings see the worst of the salt air. Stainless edge metal and welded seams hold up where standard fasteners fail.
Sunrise Highway corridor
Larger commercial and warehouse buildings with flat roofs. TPO and EPDM systems with new drains and corrected slope are the usual spec.
Salt air corrosion on fasteners and edge metal
Standard galvanized fasteners can fail years earlier than they would inland. We spec corrosion-resistant plates and stainless edge metal on coastal Freeport jobs.
Nor'easters driving rain sideways into seams
Wind-driven rain finds weak seams and flashing that pass a normal rain test. We weld or splice every seam and rebuild flashing at every penetration.
Freeze-thaw cycles in January and February
Water gets into small gaps, freezes, and widens them. Ice and water shield at eaves and correct attic or roof-deck ventilation reduce ice dam risk.
Nassau County permit requirements for full tear-offs
We pull permits and schedule inspections so your replacement is documented and code-compliant. Unpermitted work can complicate insurance claims and resale.
Before and after
What a successful service visit changes.
Retail Strip: 22-Year-Old Modified Bitumen
Before
A 6,000 sq ft retail strip in Freeport had a 22-year-old modified bitumen roof with three active leaks, ponding water near the back wall, and saturated insulation under the top ply. The owner had paid for four patches in two years.
After
We tore off to the deck, replaced 400 sq ft of rotted sheathing, installed new insulation and white TPO with welded seams, and corrected the slope toward new drains. Seven working days start to finish.
Maintenance: We recommend an annual inspection each spring to clear drains and check flashing. With that, the TPO system should hit 20 years before it needs attention.
Waterfront Restaurant: Grease-Damaged EPDM
Before
A restaurant near Woodcleft Avenue had an EPDM roof that kitchen grease had degraded around the exhaust fans. Seams were lifting, and the health inspector had flagged ceiling stains in the prep area twice.
After
We replaced the EPDM with PVC membrane rated for grease exposure, installed new curb flashing at every exhaust fan, and corrected the slope toward new drains. Five days on site.
Maintenance: Quarterly checks around exhaust fans and a yearly drain clearing keep the PVC membrane clean and the warranty valid.
Baldwin Multi-Family: Three Layers of Shingles
Before
A multi-family building in Baldwin had three layers of asphalt shingles, rotting decking around the chimney, and ice dams every winter at the north eaves. The owner was getting leak calls from two units each spring.
After
Full tear-off to the deck, new sheathing around the chimney, ice and water shield at the eaves, new underlayment, architectural shingles, and new flashing. Six days, and the ice dams stopped.
Maintenance: Annual gutter cleaning each fall and a spring roof check keep the shingles and flashing in good shape. The building appraised higher at refinance.
Problems we solve
Problems a New Commercial Roof Solves
Most Freeport commercial roofs we replace were failing in one of these ways. If any of them sound familiar, a replacement is likely cheaper than another year of repairs.
Ponding water on flat roofs that never dries
Standing water adds weight, breaks down seams, and finds every weak point. Left alone, it turns a repairable roof into a full tear-off within a couple of seasons. We correct the slope during replacement, install new drains and scuppers, and spec a membrane rated for occasional ponding. Water leaves the roof instead of sitting on it.
Blistering and bubbling membrane
Blisters mean moisture is trapped under the membrane. Patching the blister hides the problem while the wet insulation spreads damage sideways across the deck. A full replacement removes the saturated layers, replaces wet decking, and installs a new assembly that starts dry. No trapped moisture, no recurring blisters.
Flashing failure at walls and curbs
Failed flashing is the number one source of commercial roof leaks. Water gets behind the membrane and shows up as ceiling stains far from the actual entry point. We install new roof flashing at every penetration, curb, and wall during replacement, with new counterflashing and sealant. The details that cause most leaks get rebuilt, not reused.
Storm damage and hail bruising
Wind-lifted membrane and hail bruises open paths for water that may not leak until the next nor'easter. By then, the damage has spread under the surface. We document storm and hail damage for insurance, then replace the affected system with a wind-rated assembly. New fastening patterns meet current uplift requirements for coastal Nassau County.

Customer stories
What Freeport Owners Say
Dana R.Property Manager, Freeport
We had three leaks in two years and kept paying for patches. Roof Repaire Freeport cut cores, showed us the saturated insulation, and replaced the whole TPO system in eight days. No leaks since, and the tenants stopped calling. They also kept the dumpster out of the tenant lot, which mattered.
Marcus T.Restaurant Owner, Nautical Mile
Kitchen grease had wrecked our old flat roof. They spec'd PVC instead of TPO because of the grease exposure and walked me through why. Tear-off took three days, install took five. Health inspector came through mid-job and had no issues with the site. That says a lot.
Ellen K.Building Owner, Baldwin
I got four quotes for commercial roof replacement near me in Freeport and theirs was the only one with core cuts and photos. They found rotting decking two other contractors missed. Price was in the middle, work was clean, and they swept for nails every single day. Would use them again.
How much does commercial roof replacement cost in Freeport NY?
Most commercial roof replacement projects in Freeport NY run $8 to $18 per square foot in 2026, so a 5,000 sq ft flat roof typically lands between $40,000 and $90,000. TPO and EPDM sit at the lower end, PVC and modified bitumen run higher, and metal systems cost more. Tear-off layers, deck repairs, and insulation thickness move the number most.
How long does commercial roof replacement take in Freeport?
A typical 5,000 to 10,000 sq ft commercial roof replacement in Freeport takes five to ten working days from tear-off to final inspection. Small storefronts under 3,000 sq ft can finish in three to four days. Weather, deck repairs, and how many layers need stripping are the biggest schedule variables. We give you a day-by-day timeline before we start.
