What is included
What our flat roof repair includes
Every flat roof repair job includes a full inspection, the repair itself, water testing, cleanup, and a written warranty. Here is what you get when you hire us.
Full roof inspection
We walk the entire roof, not just the area you called about. We check seams, flashing, drains, penetrations, and decking. You get photos and a written report of everything we find, including issues that are not urgent yet.
Leak source identification
We use moisture meters and infrared imaging to trace water back to its entry point. This prevents us from patching the wrong spot and ensures the repair actually stops the leak.
Membrane repair or replacement
We cut out the damaged section and install new membrane matching your existing system. TPO and PVC get heat-welded. EPDM gets spliced. Modified bitumen gets torched or cold-applied. Every seam is rolled and sealed.
Flashing and sealant work
Most flat roof leaks start at flashing. We reseal or replace flashing around vents, pipes, edges, and HVAC units. We use roofing sealant rated for coastal weather and temperature swings.
Water testing
After the repair, we flood-test the area or run a hose over it for 20 minutes. We check inside for drips before we leave. If water gets through, we fix it on the spot at no extra charge.
Cleanup and warranty
We remove all old material, fasteners, and debris. Your property is left clean. You receive a written workmanship warranty plus the manufacturer warranty on any new materials we installed.

Service overview
Flat roof repair Freeport NY: what it involves
Flat roof repair Freeport NY is the process of restoring a low-slope roof system so it sheds water again, whether that means patching a punctured TPO membrane, resealing failed flashing, or replacing saturated insulation under a blistered modified bitumen surface. We start by locating the actual entry point, not just the ceiling stain. Water travels along decking before it drips, so the leak is often 10 to 15 feet from where you see the damage. We cut out the failed section, dry the deck, install new membrane, and heat-weld or seam-roll every edge so the repair holds through the next storm.
- Stop leaks fast — A small membrane puncture can let in 50 gallons of water during a single summer storm. We locate the entry point with moisture meters and infrared imaging, then seal it the same day so your ceiling, insulation, and drywall stay dry.
- Extend roof life — A properly patched TPO or EPDM membrane can add 8 to 12 years to a flat roof that would otherwise need full replacement. We repair the failed section, reinforce the surrounding seams, and leave the rest of the system intact.
- Prevent deck rot — Water trapped under a flat roof rots the plywood decking and rusts the fasteners. Once the deck softens, repair costs triple because we have to remove and replace structural panels. Fixing the membrane early keeps the deck solid.
- Lower energy bills — Saturated insulation loses most of its R-value. A dry, sealed flat roof keeps conditioned air inside, which can cut summer cooling costs by 10 to 15 percent. We replace wet insulation with new rigid board while we are in there.
- Same-day estimates — Call before noon and we can usually have an estimator on your roof the same afternoon. You get a written price before any work begins, and that price does not change unless you approve additional scope. No surprise line items.
- 21 years local — We have been fixing flat roofs in Freeport since 2005. We know which neighborhoods flood, which building styles have the worst drainage, and which inspectors will be checking your permit. That local knowledge saves you time and money.
- Emergency response — When a storm tears open your flat roof at 2 a.m., we answer. Our emergency flat roof repair Freeport New York crew carries tarps, seam tape, and temporary sealant to stop the water that night and schedule the permanent repair for the next dry day.
- Workmanship warranty — Every flat roof repair we do comes with a written workmanship warranty on top of the manufacturer material warranty. If our repair fails within the warranty period, we come back and make it right at no cost to you.
The service timeline
How our flat roof repair process works
Call and schedule
Call us at 342425679 or book online. We ask what you are seeing, when it started, and whether the roof is residential or commercial. Most Freeport jobs get a same-day or next-morning inspection slot. You get a text when the crew is on the way.
On-roof inspection
We walk the roof, check every seam, flashing point, drain, and penetration. Moisture meters and infrared scans find water trapped under the membrane. You get photos of the problem areas and a written scope before we start.
Repair and seal
We cut out the failed membrane, dry or replace the decking, install new insulation if needed, and lay in the replacement material. TPO and PVC get heat-welded; EPDM gets spliced with seam roller and adhesive; modified bitumen gets torched or cold-applied. Every edge gets roofing sealant.
Water test
Before we pack up, we flood-test the repaired area or run a hose over it for 20 minutes while checking inside for drips. If anything weeps, we fix it on the spot. You get a written confirmation that the repair held.
Cleanup and warranty
We haul away every scrap of old membrane, fasteners, and packaging. Your driveway and gutters are cleaner than when we arrived. You get a workmanship warranty on the repair plus the manufacturer warranty on the materials we installed.
Tools and methods01 02 03 04 05 06 07 08 09 10
Tools and methods we use
Moisture meter
Detects water trapped under the membrane and inside insulation. We use it to map the full extent of the damage before we cut anything open.
Infrared camera
Shows temperature differences that reveal wet insulation and hidden leaks. Especially useful on large commercial roofs where the leak source is not obvious.
Seam roller
Presses TPO and PVC seams flat after heat-welding to ensure a watertight bond. Every seam gets rolled before we move on.
Roofing safety harness
Keeps our crew safe on steep or high flat roofs. We use harnesses and ladder stabilizers on every job, no exceptions.
Air compressor
Powers pneumatic tools and helps us test seam integrity. We also use it to clear debris from drains and gutters.
Utility knife and pry bar
Cuts membrane cleanly and removes old flashing, fasteners, and damaged material. Sharp tools mean cleaner cuts and better patches.
Heat-welded seam repair
For TPO and PVC membranes, we use a hot-air welder to fuse new membrane to the existing roof. The weld is stronger than the membrane itself. We test every seam with a seam roller and probe.
Infrared leak detection
We scan the roof with an infrared camera to find wet insulation and hidden moisture. This lets us target the repair precisely instead of replacing large sections that are still dry.
Flood testing
After the repair, we flood the area with water or run a hose for 20 minutes. We check inside for drips. If water gets through, we fix it before we leave.
Manufacturer specification compliance
We install every membrane and flashing detail to the manufacturer's written specification. That keeps your material warranty valid and ensures the repair performs as designed.
Where this service helps
When to call for flat roof repair
You notice a brown water stain spreading on your ceiling after a rainstorm.
We inspect the roof, trace the leak with moisture meters, and repair the source. Most ceiling stains come from failed flashing or an open seam, not a hole in the middle of the roof. The leak stops, the stain dries out, and you avoid replacing the drywall and insulation underneath.
Your flat roof has standing water 48 hours after the rain stops.
We find the low spots, clear the drains, and repair any membrane damage caused by the ponding. If the slope is wrong, we can add tapered insulation to correct it. Water drains properly, the weight comes off the structure, and the membrane stops deteriorating.
A storm tears a section of membrane off your commercial building.
We tarp the open area the same day to stop water intrusion. Once the weather clears, we install new membrane and flashing, matching the existing system. Your business stays dry, your inventory is protected, and the roof is back to full strength.
Your flat roof is more than 15 years old and you are not sure if it needs repair or replacement.
We inspect the full system, check the deck and insulation, and give you an honest assessment. If a repair will add years of life, we say so. If replacement is the better investment, we explain why. You make a decision based on facts, not a sales pitch, and you get the most value from your roofing budget.
Local execution
How flat roof repair works in Freeport
Freeport's climate is hard on flat roofs. Summer heat bakes the membrane, winter freeze-thaw cycles open seams, and nor'easters drive rain sideways under flashing. The village has a mix of older commercial buildings downtown and residential neighborhoods with flat-roof garages and additions. Many of those roofs were installed 20 or 30 years ago and are now at the end of their service life. We know the local building department requirements for Nassau County and pull permits when the job needs one. If you are searching for flat roof repair near me Freeport, we are likely already working in your neighborhood. We keep our trucks stocked with TPO, EPDM, and modified bitumen so we can complete most repairs in a single visit.
Downtown Freeport
Older commercial buildings with flat roofs that need regular drain clearing and flashing maintenance. Many have modified bitumen systems from the 1990s.
Freeport waterfront
Salt air and wind-driven rain accelerate corrosion on flashing and fasteners. We use coastal-rated sealants and check every penetration.
North Freeport
Residential neighborhoods with flat-roof garages and additions. Common issues include ponding water and failed flashing at the house-to-garage transition.
South Freeport
Mix of residential and light commercial. We see a lot of TPO roofs installed after Sandy that are now due for seam repairs.
Coastal salt air and high humidity
Salt accelerates corrosion on metal flashing and fasteners. We use corrosion-resistant materials and check every metal component during inspection.
Freeze-thaw cycles in winter
Water gets into small cracks, freezes, and expands. This opens seams and tears flashing. We seal every vulnerable point before winter.
Summer thunderstorms and nor'easters
Heavy rain overwhelms drains and finds weak spots. We clear drains and repair membrane damage after every major storm.
Before and after
What a successful service visit changes.
TPO membrane repair on commercial building
Before
A 30x40 section of TPO membrane on a Freeport commercial building had multiple punctures from a fallen tree limb. Water was leaking into the warehouse space below, damaging inventory. The existing membrane was 12 years old but still had life left.
After
We cut out the damaged section, installed new TPO membrane, and heat-welded every seam. The repair blended with the existing roof and passed a 30-minute flood test. The leak stopped and the inventory stayed dry.
Maintenance: We recommended annual inspections and keeping tree limbs trimmed back at least 10 feet from the roof edge.
Modified bitumen flashing repair
Before
A homeowner in Baldwin had a persistent leak around a plumbing vent. Three previous patch jobs had failed because they only sealed the top of the flashing, not the base. Water was running down the pipe and into the ceiling.
After
We removed the old flashing, cleaned the area, and installed new flashing with proper overlap and sealant. The repair took two hours and cost $450. The ceiling stain dried out and no new leaks appeared.
Maintenance: We suggested checking the flashing annually and resealing if the sealant shows signs of cracking.
Ponding water correction on flat roof
Before
A flat roof on a Merrick home had standing water 48 hours after every rain. The membrane was starting to blister and the homeowner was worried about structural damage. The roof was only 8 years old.
After
We added tapered insulation to correct the slope and installed a new drain in the low spot. The ponding stopped, the blisters were repaired, and the roof now drains completely within 24 hours of a storm.
Maintenance: We recommended clearing the new drain twice a year and checking the membrane after winter for any freeze damage.
Problems we solve
Flat roof problems we fix in Freeport
These are the most common flat roof issues we see on Freeport and Nassau County buildings. If you recognize any of them, call us before the damage spreads.
Ponding water on flat roofs
Standing water adds thousands of pounds of weight, accelerates membrane breakdown, and finds every weak seam. After a few seasons, the membrane fails completely. We locate the low spots, repair or replace the affected membrane, and improve drainage by adjusting insulation slopes or adding drains. We also clear clogged gutters and downspouts that cause water to back up.
Blistering and bubbling membrane
Blisters mean water or air is trapped under the membrane. They grow with every temperature swing and eventually crack open, letting water into the insulation and deck. We cut out the blister, dry the area, and install new membrane with proper adhesive. If the insulation underneath is wet, we replace it. We then seam-roll and seal the patch so it bonds flush with the surrounding roof.
Failed flashing around vents and pipes
Flashing failure is the number one cause of flat roof leaks. Water runs down the pipe, through the gap, and into your ceiling. It often shows up far from the actual entry point. We remove the old flashing, clean the area, and install new flashing with proper overlap and sealant. We use roofing sealant rated for UV exposure and temperature extremes. Every penetration gets checked, not just the one that is leaking.
Clogged gutters causing roof damage
When gutters and drains clog, water backs up under the membrane and rots the fascia and deck edge. In winter, that water freezes and expands, cracking seams and flashing. We clear all debris from gutters, downspouts, and roof drains. If the drainage system is undersized, we recommend adding capacity. We also check the membrane around the drain for damage caused by the backup.

Customer stories
What Freeport customers say
Maria G.Homeowner, Freeport
We had a leak over our kitchen for months. Two other companies told us we needed a full roof replacement. Roof Repaire Freeport found the actual problem was failed flashing around the vent pipe. They fixed it in three hours for under $600. No leak since, and that was two winters ago.
James R.Property Manager, Baldwin
I manage six commercial buildings with flat roofs. Roof Repaire Freeport handles all our repairs. They respond same day, tarp when needed, and their paperwork is clean enough for our insurance company. They replaced a 40x60 section of TPO membrane on one building and it has held through two nor'easters.
Denise L.Homeowner, Merrick
After the storm last spring, water was pouring into our garage. I called at 7 a.m. and their crew was on the roof by 10. They tarped it, came back two days later, and did the permanent repair. The price was exactly what they quoted. I have already recommended them to two neighbors.
