What is included
What's Included in a TPO Roof Installation
Every TPO roof we install includes the membrane, the fastening system, the flashing, and the labor to put it down right. What changes from job to job is the tear-off, the deck repair, and the insulation. Here's what you get when we do the work.
Full Tear-Off and Disposal
We strip the old membrane, insulation, and any wet layers down to the deck. We haul it all away and dispose of it properly. No dumpster sitting in your driveway for a week after we're done.
Deck Inspection and Repair
Once the old roof is off, we inspect the decking for rot and soft spots. Rotted sections get cut out and replaced with new plywood. We don't cover up bad decking with new membrane, because that's how roofs fail early.
Cover Board and Insulation
We install a cover board over the deck and insulation with the R-value that fits your building. The cover board protects the membrane from foot traffic and punctures. Insulation keeps heat out in summer and in during winter.
TPO Membrane and Heat-Welded Seams
We roll out the TPO membrane, position it, and heat-weld every seam with a hot-air welder and seam roller. We probe-test the seams before we move on. The membrane is one continuous sheet when we're done, not a patchwork.
Flashing, Drains, and Edge Metal
Flashing goes up at walls, curbs, vents, and drains. We install new edge metal and drip edge so water sheds off the roof instead of running behind the fascia. Drains get checked and cleared so water moves.
Warranty Registration and Walkthrough
We register the manufacturer warranty on your TPO membrane and give you the paperwork. Then we walk the roof with you, show you the seams and drains, and explain how to keep it maintained. You'll know exactly what you bought.

Service overview
What TPO Roofing in Freeport Actually Involves
TPO roofing is a single-ply thermoplastic membrane, usually 45 to 80 mils thick, rolled out over a flat or low-slope deck and fastened or adhered in place. The seams are heat-welded with a hot-air welder, which fuses the panels into one continuous sheet instead of relying on adhesive that dries out. On a typical Freeport flat roof, we strip the old layers, inspect the decking, install a cover board and underlayment, then run the membrane up and over every edge with proper flashing.
Freeport sits right on the water, so roofs here deal with salt air, nor'easters, and freeze-thaw cycles that pry open seams on older flat roofs. Most of the flat roofs we see are on capes, ranches, and commercial buildings near the Nautical Mile and along Woodcleft Avenue, and many are 20-plus years old. A TPO roof installation in Freeport New York gives you a reflective white surface that drops attic temps, sheds water instead of holding it, and holds up to the coastal weather far better than patched modified bitumen.
- Heat-Welded Seams That Stay Sealed — Adhesive seams fail first on older flat roofs. We heat-weld every TPO seam with a hot-air welder and test them, so the membrane becomes one continuous sheet. That's the difference between a roof that leaks in year three and one that holds for 20-plus years.
- White Surface Cuts Cooling Bills — A white TPO membrane reflects most of the sun's energy instead of absorbing it. Freeport homeowners with flat roofs over living space often see attic temperatures drop 15 to 25 degrees in July and August, which takes real pressure off the AC and the electric bill.
- Handles Ponding and Coastal Rain — TPO is engineered for low-slope roofs where water drains slowly. We set the membrane over a tapered or cover-board system so water moves to the drains and scuppers. That matters when a nor'easter dumps two inches in an hour and your old roof would have been a swimming pool.
- Repairable Without a Full Tear-Off — If a branch punches through or a seam lifts, TPO patches weld right onto the existing membrane. No tearing off half the roof. That keeps TPO roof repair Freeport New York costs low and gets you watertight again the same day in most cases.
- Same-Day Estimates, No Charge — Call before noon and we'll be on your roof the same day in most of Nassau County. You get a written price before any work starts. No pressure, no follow-up sales calls, no 'today only' discounts.
- We Fix the Cause, Not the Stain — A ceiling stain means water traveled. We trace it back to the actual failure, whether that's a lifted seam, flashing failure at a wall, or a clogged drain. Patching the stain and walking away is how roofs get ruined.
- Coastal Roofing Experience — Freeport NY TPO roof work is different from inland roofing. Salt air, wind-driven rain, and freeze-thaw cycles punish seams and flashing. We spec fasteners and edge metal for coastal conditions, not the cheapest option on the shelf.
- Warranties You Can Actually Use — We register the manufacturer warranty on your TPO membrane and back the install with our own workmanship warranty. If a seam lifts or a drain leaks, you call us and we come back. That's the whole point of hiring a local roofer.
The service timeline
How Our TPO Roof Installation Works
Free Roof Inspection
We walk the roof, check the deck, look for ponding, blisters, flashing failure, and clogged gutters causing roof damage. You get photos and a straight answer on whether TPO is the right call or a repair buys you more time. Takes about 45 minutes on a typical Freeport flat roof.
Written Scope and Pricing
You get a written scope with the membrane thickness, brand, insulation R-value, and total price before we start. No surprise line items. Most residential flat roofs in Freeport run $9,500 to $18,000 depending on square footage and how many old layers come off.
Tear-Off and Deck Repair
We strip the old membrane and any wet insulation, then inspect the decking for rot. Rotted sections get cut out and replaced. A 1,200-square-foot roof usually takes one to two days for tear-off and deck work, depending on how much damage we find underneath.
Membrane Installation
We install the cover board, ice and water shield at the edges, then roll out and heat-weld the TPO membrane. Every seam gets a seam roller and a probe test. Flashing goes up at walls, curbs, and drains. A typical Freeport flat roof takes two to three days to install.
Final Walkthrough and Warranty
We clean up, run a hose test over the seams, and walk the roof with you. You get the manufacturer warranty paperwork and our workmanship warranty in hand. We also show you how to keep the drains clear so ponding water on flat roofs never becomes your problem again.
Tools and methods01 02 03 04 05 06 07 08 09
Tools and Methods We Use on TPO Roofs
Hot-Air Welder
The core tool for TPO. It heats the membrane at the seam to 900-plus degrees and fuses the two panels into one. Every seam on your roof gets welded, then probe-tested.
Seam Roller
After welding, we run a seam roller over the joint to press the fused membrane together. It catches air pockets and ensures a tight bond. Skipping this step is how seams fail early.
Roofing Safety Harness and Ladder Stabilizer
Flat roofs still have edges. We use fall protection on every job, and ladder stabilizers keep the ladder from sliding on the fascia. Safety isn't optional on a two-story roof.
Moisture Meter
We use it to find trapped moisture in the deck and insulation before we install new membrane. If we cover wet insulation, the new roof blisters. The meter tells us what's wet and what's dry.
Air Compressor and Roofing Nail Gun
For fastening cover board and insulation to the deck before the membrane goes down. We also use a roofing hammer and pry bar for tear-off and a utility knife and chalk line for layout.
Heat-Welded Seam System
We weld every TPO seam with a hot-air welder and test each one with a probe. This is the method that separates a 20-year TPO roof from a 5-year one. Adhesive seams fail; welded seams hold.
Tapered Insulation for Drainage
On roofs that pond, we install tapered insulation to create slope toward the drains. It's the permanent fix for standing water. Water moves off the roof instead of sitting on the membrane.
Cover Board Over Deck
We set a cover board over the deck before the membrane. It protects the TPO from foot traffic, hail, and punctures. It also gives the membrane a smooth surface so it lays flat and welds clean.
Flashing Detail at Walls and Curbs
Flashing failure is the second most common leak source after seams. We detail every wall, curb, vent, and drain with reinforced flashing and proper termination. No shortcuts at the edges.
Where this service helps
When TPO Roofing Makes Sense in Freeport
You have a flat roof over a back addition or garage that's been patched multiple times and still leaks.
We tear off the old membrane, inspect the deck, and install a new TPO system with heat-welded seams and proper flashing. The patching cycle ends. You get a roof that's watertight and warrantied. No more buckets in the garage. No more calling a roofer every time it rains. One installation, 20-plus years of service.
You own a commercial building in Freeport with a flat roof that ponds water and has HVAC units sitting on it.
We install a commercial-grade 80-mil TPO membrane with reinforced flashing around the curbs and equipment. We set it up so the roof drains properly and the membrane handles foot traffic from service techs. A commercial roof that handles equipment traffic, drains fast, and doesn't leak into your tenant spaces. Minimal disruption to your business during install.
Your home has a low-slope roof section that's been covered in modified bitumen for 25 years and is at the end of its life.
We remove the old bitumen, repair the deck, and install a white TPO membrane. The reflective surface cuts heat gain, and the heat-welded seams outlast the old torch-down system by a wide margin. Lower summer cooling costs, no more seam failures, and a roof that's warrantied for decades instead of years.
You're buying or selling a Freeport home with a flat roof and the inspection flagged it.
We inspect the roof, document the condition with photos, and give you a written report with repair and replacement options. If it needs replacement, we can have a TPO system on before closing. A clear picture of the roof's condition for the sale, and a new TPO roof if it's needed. No surprises at the closing table.

How TPO Roofing Works in Freeport's Climate
Freeport roofs deal with salt air, nor'easters, and freeze-thaw cycles that most inland roofs never see. The salt air corrodes fasteners and edge metal, so we spec corrosion-resistant fasteners and heavier edge metal on coastal jobs. Winter freeze-thaw cycles pry at seams and flashing, which is why heat-welded TPO outperforms adhesive-seamed systems here. Summer heat bakes flat roofs, and a white TPO membrane reflects most of that heat instead of pushing it into your attic. Most of the flat roofs we work on in Freeport are on capes, ranches, and commercial buildings near the water, and many are 20-plus years old with multiple layers of old roofing. When you search for TPO roofing services Freeport, you're usually dealing with a roof that's been patched too many times. We'll tell you straight whether a repair buys you time or whether it's time for a new TPO roof installation Freeport NY homeowners can count on.
Nautical Mile / Woodcleft Avenue
Commercial buildings and restaurants near the water deal with grease, salt air, and rooftop equipment. PVC or TPO with reinforced flashing handles it best.
Freeport Village residential blocks
Many capes and ranches have flat roofs over back additions and garages. These are the most common TPO replacement jobs we do in 11520.
South of Sunrise Highway
Closer to the water means more salt air and wind-driven rain. We spec heavier edge metal and corrosion-resistant fasteners on these roofs.
North Freeport near the parkway
Slightly more tree cover means more debris in gutters and drains. Clogged drains cause ponding, which is the top cause of flat roof leaks we see here.
Salt air corrosion on fasteners and edge metal
Standard fasteners rust out in a few years near the water. We use corrosion-resistant fasteners and heavier edge metal so the roof holds up to the coastal environment.
Freeze-thaw cycles in winter
Water gets into seams and flashing, freezes, and expands. It pries joints apart. Heat-welded TPO seams handle this far better than adhesive-seamed systems.
Summer heat and UV on flat roofs
Black or dark roofs absorb heat and push it into the building. White TPO reflects it, which drops attic temps and takes pressure off the AC.
Nor'easters and wind-driven rain
Wind-driven rain finds every weak flashing detail. We reinforce flashing at walls, curbs, and edges so the roof handles storm-force rain without leaking.
Before and after
What a successful service visit changes.
Freeport Garage Roof: From Patching to TPO
Before
A detached garage in Freeport had a 25-year-old modified bitumen roof with three active leaks and standing water after every rain. The owner had patched it four times in five years. The decking under the worst leak was soft and rotted.
After
We tore off the old bitumen, replaced 120 square feet of rotted decking, installed a cover board, and set a 60-mil white TPO membrane with heat-welded seams. The ponding stopped. No leaks through the next two storm seasons.
Maintenance: Clear the gutter and drain twice a year, and have us inspect the seams every two years. The membrane is warrantied for 20 years, and it should hit that easily with basic maintenance.
Baldwin Commercial Building: Ponding Fixed
Before
A six-unit building in Baldwin had a flat roof that ponded two inches deep after every storm. The drains were undersized and the roof had no slope. Tenants were calling about ceiling stains every month.
After
We installed tapered insulation to create slope toward new, larger drains, then set an 80-mil TPO membrane with reinforced flashing around the HVAC curbs. Water now drains within an hour of a storm. The tenant leak calls stopped.
Maintenance: We set the building up on a twice-a-year maintenance plan. We clear the drains, check the seams, and inspect the flashing. It's the cheapest way to protect a commercial roof.
Merrick Home Addition: Leak Traced and Fixed
Before
A homeowner in Merrick had a ceiling stain in the kitchen that three roofers had tried to fix by patching the flat roof over the addition. The stain kept coming back. Nobody had traced the leak to its actual source.
After
We used a moisture meter and hose testing to trace the leak to a failed seam near the drain, 12 feet from the stain. We cut out the failed section, dried the deck, and welded a new TPO patch. The stain dried out and never came back.
Maintenance: We showed the homeowner how to keep the drain clear and what to look for at the seams. A quick visual check after big storms catches most problems before they become leaks.
Problems we solve
Flat Roof Problems We Solve in Freeport
Most flat roof calls we get in Freeport come down to four problems. Here's what they look like, why they matter, and how we fix them.
Ponding water on flat roofs after every storm
Standing water finds every weak seam and flashing joint. Left alone, it rots the deck and adds hundreds of pounds of load to the structure. It's the number one cause of flat roof leaks we see. We install a tapered insulation system or adjust the slope so water moves to the drains. Then we set a new TPO membrane over it. The ponding stops, and the roof drains within hours of a storm instead of days.
Lifted or failed seams on older membrane roofs
Adhesive-seamed roofs fail at the seams first. Once a seam lifts, water gets under the membrane and travels. You get ceiling stains far from the actual leak, and the deck starts to rot. We cut out the failed section, dry the deck, and weld a new TPO patch over it. If the seams are failing across the whole roof, we'll tell you it's time for a replacement instead of chasing patches.
Blistering and bubbling membrane
Blisters mean moisture is trapped under the membrane. They get bigger with every freeze-thaw cycle, and eventually they crack open and leak. Ignoring them leads to a full tear-off instead of a repair. We open the blister, dry the area, and either patch it or replace the section. If blisters cover most of the roof, the trapped moisture is everywhere and a new TPO system is the honest answer.
Clogged gutters and drains causing roof damage
When drains clog, water backs up onto the roof and finds its way in. It also rots the fascia and soffit. Most of the 'leaks' we get called for in Freeport start with a clogged drain, not a failed membrane. We clear the drains and gutters, then check the membrane and flashing for damage the backup caused. We also show you how to keep them clear so it doesn't happen again next storm season.

Customer stories
What Freeport Customers Say
Dana R.Homeowner, Freeport
Our flat roof over the back addition had been leaking for two years. Three other roofers just wanted to patch it. Roof Repaire Freeport found the actual problem, which was a failed seam near the drain, and installed a new TPO membrane over the whole section. No leaks through two nor'easters since. Clean crew, fair price.
Marcus T.Property Manager, Baldwin
We manage a six-unit building in Baldwin with a flat roof that was ponding water every storm. They installed a tapered TPO system with new drains. The ponding is gone, and the tenants stopped calling about ceiling stains. They worked around our schedule and cleaned up every day.
Priya S.Homeowner, Merrick
Got three quotes for a TPO roof on our garage. Roof Repaire Freeport was the only one who explained the membrane thickness and showed us the difference between 45-mil and 60-mil. They installed the 60-mil and it's been solid. The white surface made a real difference in the garage temperature.
How much does TPO roofing cost in Freeport NY?
Most TPO roof installations in Freeport run $9,500 to $18,000 for a residential flat roof, or $8 to $14 per square foot installed. Commercial roofs and larger homes go higher. The biggest cost drivers are square footage, how many old layers need tear-off, whether the decking is rotted, and the membrane thickness you choose. We give you a written price before we start.
How long does a TPO roof last in Freeport?
A properly installed 60-mil TPO membrane lasts 20 to 30 years in Freeport's climate. The 80-mil commercial-grade membrane can push past 30. What kills TPO roofs early here is poor installation, standing water from clogged drains, and foot traffic. Keep the drains clear and have the roof inspected every two years, and you'll get the full life out of it.

Is TPO roofing good for Freeport NY climate?
Yes. TPO handles the freeze-thaw cycles, salt air, and wind-driven rain that hit Freeport roofs every winter. The heat-welded seams stay fused through temperature swings that destroy adhesive-seamed roofs. The white surface also reflects summer sun, which keeps attic temps down. It's one of the best flat-roof options for coastal Long Island.
