What's included
What Our Flat Roof Repair Service Includes
Every flat roof repair starts with a real diagnosis and ends with a tested repair. Here is what is covered on a standard visit, and what we handle as an add-on when the inspection turns up more than expected.
Full roof inspection
We walk the entire flat roof, not just the area you called about. Moisture meter and infrared camera readings on the field, seams, flashing, drains and penetrations. You get photos of anything we find, including problems outside the original leak.
Leak source diagnosis
We trace the water to its entry point rather than patching where the stain shows on your ceiling. On flat roofs those are often different locations. This step is why our repairs hold instead of recurring every spring.
Membrane patching
EPDM, TPO and modified bitumen patches cut to size, primed, rolled and sealed. We use matching material from the same manufacturer where possible so the repair blends into the existing system and warranty.
Flashing and boot repair
Termination bars, wall flashing, pipe boots and drain collars reworked or replaced. These are the most common leak points on a flat roof, and patching the membrane without fixing the flashing just moves the leak.
Drain and gutter clearing
We clear roof drains, scuppers and gutter runs so water leaves the roof. Ponding water is the number one enemy of a flat membrane, and a five-minute drain clearing prevents a lot of damage.
Cleanup and photo report
Magnetic sweeper over the lawn and driveway, debris hauled off, and a photo record of the finished repair sent to you. We also note what to watch for and when the next inspection should happen.
Service overview
What Flat Roof Repair in Surrey Actually Involves
Flat Roof Repair in Surrey is the diagnosis and correction of a low-slope roof system that is leaking, ponding, blistering or losing its weather-tight seal. On a flat roof there is no pitch to shed water fast, so every seam, termination bar, pipe boot and drain becomes a failure point. We start with a moisture meter and infrared camera scan, then open the suspect area to see whether the problem is the membrane, the flashing, the insulation below, or all three at once.
Surrey sits in Ward County where the freeze-thaw cycle runs hard from October through April. Water finds a pinhole in a TPO seam in November, freezes, widens the gap, and by spring you have a ceiling stain. That is why so many homeowners call us for Flat Roof Leak Repair Surrey ND after the first warm week. We also get commercial flat roofing repair Surrey North Dakota calls from property managers who need a roof dried in before the next storm.
How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
How Our Flat Roof Repair Process Works
The process flexes to the condition, but these checkpoints keep decisions clear.
Call and schedule
You call +18447100795 or book online. We ask what you are seeing, where the stain is, and how old the roof is. Most Surrey jobs get a same-day or next-day inspection slot. If water is actively coming in, we treat it as emergency roof repair and get out faster.
Inspect and diagnose
We walk the roof with a moisture meter and infrared camera, check seams, terminations, pipe boots, drains and flashing. You get a straight answer on what failed and what it takes to fix it. Expect 30 to 60 minutes on a typical residential flat roof.
Repair the failure point
We cut back the damaged membrane, dry the deck, and patch with matching material, whether that is EPDM, TPO or modified bitumen. Seams get primer and lap sealant, flashing gets reworked, and pipe boots get replaced rather than patched over.
Test and verify
We flood-test or hose-test the repaired area and re-scan with the moisture meter. If the reading is still high, we keep going until it is dry. You see the results before we pack up, and we photograph the finished work for your records.
Clean up and advise
Magnetic sweeper across the lawn and driveway for nails and screws, gutters cleared of debris, and a short walkthrough of what we found. We tell you what to watch for and when to schedule the next inspection.
Tools & methods
Tools and Methods We Use on Flat Roofs
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Infrared camera
Finds wet insulation under the membrane by temperature difference. It lets us map the actual wet zone before we cut anything open, so the repair is sized correctly the first time.
Moisture meter
Confirms what the infrared camera suggests. We take readings across the field, at seams and around penetrations to verify the repair area is dry before we close it up.
Hot-air welder
Required for TPO and other heat-welded membranes. A welded seam is stronger than the membrane itself when done correctly. We hand-test every weld before we leave the roof.
Roofing ladder and safety harness
Flat roofs still have fall hazards, especially at the edges and around skylights. Every crew member is tied off and we set the ladder on stable ground before anyone goes up.
Caulking gun and lap sealant
Used on terminations, flashing edges and EPDM splice perimeters. We use manufacturer-approved sealants so the repair stays compatible with the existing membrane and warranty.
Magnetic sweeper
Runs over the lawn and driveway at the end of every job. Flat roof repairs generate screws and staples, and a sweeper keeps them out of your tires and your kids' feet.
Use cases
When Surrey Property Owners Call Us
These examples show how the service framework adapts rather than forcing every call through one repair.
Commercial TPO ponding fixed in Guildford
A small commercial building in Guildford had water ponding near a roof drain after every heavy rain. The TPO membrane around the drain had lifted, and the seam at the drain collar had opened. The property manager was getting complaints from a tenant about a ceiling stain. → We cleared the drain, cut out the lifted membrane, and welded in a new TPO section with a hot-air welder. The drain area was re-pitched with a tapered insulation cricket. A hose test confirmed water now drains off within minutes. Repair took one day.
Modified bitumen blister repair in Cloverdale
A Cloverdale homeowner had a 300 sq ft modified bitumen porch roof with three visible blisters and granule loss across the field. The blisters were soft underfoot, meaning moisture was trapped under the membrane. One blister had already torn open. → We cut out the blisters, dried the deck, and patched with matching modified bitumen. The field got a reflective coating to slow UV breakdown. The repair cost well under half of a replacement quote, and the roof passed a hose test the same day.
Problems we solve
Flat Roof Problems We Fix in Surrey
Most flat roof calls come down to a handful of failures. Here is what we see most often in Surrey, what happens if you leave it, and how we fix it.
Ponding water sitting on the membrane
We clear the drain or scupper, check the roof pitch, and add a tapered insulation cricket or re-pitch the drain area if the ponding is structural. Then we scan the wet zone and repair any membrane that lifted.
Failed seams and lap joints
We clean the seam, apply primer, and re-weld TPO or splice EPDM with proper lap sealant. Every repaired seam gets a hand test before we leave, and we re-scan the area with the moisture meter.
Cracked pipe boots and vent seals
We pull the old boot, clean the pipe and membrane, and install a new boot sized to the pipe. The base gets sealed to the membrane with compatible sealant, and we check every other penetration on the roof while we are up there.
Blistering and granule loss
We cut out the blister, dry the deck, and patch with matching membrane. If the blistering covers a large area, we will tell you honestly whether a partial re-roof makes more sense than chasing patches.
Pricing process
What Flat Roof Repair Costs in Surrey
$350 - $1,800 for most residential repairs; commercial quoted by square footage
Size of the failed area
A single pipe boot or seam is a small repair. A wet zone that covers 100 sq ft or more means cutting back more membrane, drying more deck and using more material. Square footage is the biggest single driver of cost.
Membrane type
EPDM repairs are usually the least expensive because the materials are simple. TPO requires a hot-air welder and more labor. Modified bitumen can go either way depending on whether it is torch-applied or cold-applied.
Wet insulation or decking
If the moisture meter shows saturated insulation, it has to come out and be replaced before the new membrane goes down. That adds material and labor, but skipping it guarantees the repair fails within a season.
How much does flat roof repair cost in Surrey ND?
Most residential flat roof repairs in Surrey run $350 to $1,800 depending on the size of the failed area and whether the deck is wet. A simple pipe boot or seam reseal is often under $500. If insulation and decking need replacement, expect the higher end. We give you a written price after the inspection, not before.
Can you repair a flat roof in Surrey North Dakota without replacing it?
Yes, if the membrane field is still sound. We repair EPDM, TPO and modified bitumen roofs regularly when the failure is isolated to seams, flashing, drains or penetrations. If more than about 30 percent of the field is saturated or blistered, replacement usually makes more financial sense, and we will tell you that straight.
What causes flat roof leaks in Surrey ND?
The freeze-thaw cycle is the biggest culprit here. Water gets into a seam or around a pipe boot, freezes overnight, and opens the gap wider. Ponding water from clogged drains, failed termination bars, and UV breakdown on older EPDM are the other common causes. Hail and wind damage also show up after summer storms.
How long does flat roof repair take in Surrey, North Dakota?
A typical residential repair takes two to four hours on site. Larger commercial patches or deck replacement can run one to three days. Emergency dry-ins are done in under two hours. We schedule around weather, since primer and sealant need dry conditions and above-freezing temperatures to cure properly.
