What is included
What our TPO roof leak repair includes
Every TPO repair starts with a real diagnosis and ends with a documented weld. Here is what is covered on a standard visit. If we find something outside this scope, like rotted decking or a failed drain, we tell you before we touch it and quote it separately.
Full leak diagnosis
Moisture meter readings across the suspect area, an infrared thermal imaging camera scan of the ceiling below, and a controlled water hose test to confirm the entry point. You get the readings in writing, not just a verbal guess.
Heat-welded membrane repair
We cut a patch from matching 60-mil TPO membrane, clean and prep the substrate, and hot-air weld the patch with a seam roller. The weld is tested by hand probe before we call it done. No roof cement smeared over a split seam.
Penetration and boot sealing
Pipe boots, conduit, and HVAC curbs get new collars and butyl tape, then a welded TPO skirt. These are the most common leak points on Conroe flat roofs, so we treat every penetration on the repair path, not just the one that failed.
Flashing and termination repair
Wall flashing, parapet terminations, and curb details get a new termination bar and fresh roof sealant, plus a welded membrane skirt where the old one pulled loose. This closes the second most common leak path after seams.
Post-repair water test
We re-run water over the repaired area and confirm no moisture appears below. Final moisture meter readings and two weld photos go into your file the same day, which is useful for insurance claims and property records.

Service overview
What TPO Roof Leak Repair in Conroe actually involves
TPO Roof Leak Repair in Conroe is the process of locating water entry on a thermoplastic polyolefin membrane roof and restoring the waterproof layer with heat-welded patches, seam welds, and sealed penetrations. TPO is a single-ply white membrane common on Conroe commercial buildings, retail centers, and modern home additions. Leaks start at the weakest points: seam separation, vent boot leak, pipe penetration, or flashing leak at a wall or curb. We test with a water hose test kit, confirm with a moisture meter, then repair the exact spot instead of coating the whole roof.
Conroe sits in a hot, humid pocket of Southeast Texas where summer surface temps on a white TPO membrane push past 150 degrees and afternoon thunderstorms dump two inches in an hour. That cycle works seams loose. Most of the Conroe TPO roof leak repair service calls we run start as a ceiling water stain near a rooftop unit or an attic moisture reading after a storm. If you have been searching TPO roof leak repair in Conroe TX near me, the fix is usually a seam weld and a new termination bar, not a full tear-off.
- Stop the leak same day — Most emergency TPO roof leak repair Conroe TX calls are sealed within four hours of arrival. We carry 60-mil TPO membrane, seam rollers, and a hot-air welder on every truck, so a separated seam gets welded shut on the first visit instead of tarped and forgotten.
- Find the real entry point — Water rarely drips straight down. We use an infrared thermal imaging camera and a moisture meter to trace the path from the wet ceiling back to the actual breach, which is often 10 to 20 feet away at a roof seam or pipe boot. That is how we avoid repeat callbacks.
- Protect the deck and insulation — A slow TPO leak soaks the polyiso insulation board and rusts the metal deck underneath. Catching it early keeps a $400 repair from becoming a $9,000 deck replacement. We document moisture readings before and after so you can see the roof dried out.
- Warranty-backed workmanship — Our heat-welded repairs carry a workmanship warranty, and where the original membrane is a Firestone, Carlisle SynTec, or GAF product, we follow that manufacturer's repair detail so your existing system warranty stays intact. We photograph every weld for your records.
- Same-day emergency response — Call before noon and we can usually have a technician on your roof the same afternoon. For active leaks over electrical equipment or inventory, we dispatch 24/7 and tarp the area first, then return in daylight to weld a permanent patch. That two-stage approach protects your building overnight.
- We weld, we do not smear — A tube of roof cement over a separated seam buys you a month. We cut out the failed seam and hot-air weld a new strip of TPO membrane into place, which restores the membrane as one continuous sheet. That is the difference between a repair and a patch.
- Straight pricing, no surprises — Diagnostic visits and repairs are quoted before we start. Affordable TPO roof leak fixing Conroe Texas does not mean cheap materials, it means you are not paying for a full re-roof when a $500 seam repair solves the problem. We tell you when replacement is the smarter money.
- Local to Montgomery County — We work Conroe, The Woodlands, Willis, Montgomery, Magnolia, Spring, Tomball, Shenandoah, and Oak Ridge North. Being local means we know which 1990s retail centers have original TPO and which subdivisions have low-slope additions that leak at the same corner every spring.
The service timeline
How our TPO leak repair process runs
Phone triage
You call (936) 304-3062 and describe where the water shows up. We ask three questions: is the ceiling actively dripping, is the roof accessible, and is there a rooftop unit nearby. That tells us whether to dispatch an emergency crew tonight or schedule a daytime inspection. Most calls get a same-day window.
Roof inspection
A technician walks the membrane with a moisture meter and scans the ceiling below with an infrared thermal imaging camera. On larger commercial roofs we fly a roof inspection drone first to map ponding water and seam separation. This step takes 30 to 60 minutes and pinpoints the breach.
Water test
We isolate the suspect area and run a controlled water hose test kit over the seam, flashing, or penetration. If water appears below within a few minutes, we have our entry point confirmed. No test, no repair, no guessing.
Heat-welded repair
We cut a patch from matching 60-mil TPO membrane, clean the substrate, and hot-air weld it with a seam roller to create a monolithic bond. Pipe boots get a new boot and butyl tape collar; wall terminations get a new bar and roof sealant. A typical repair runs two to four hours.
Verification and cleanup
We re-test the repair with water, take final moisture readings, and photograph the finished weld from two angles. You get those photos plus a written summary the same day. We sweep the roof for screws and scraps so nothing ends up in your parking lot or gutter.
Tools and methods01 02 03 04 05 06 07 08 09 10
Tools and methods we use
Infrared thermal imaging camera
Reads temperature differences on the roof and ceiling to show where water is trapped under the TPO membrane. It finds hidden leaks without tearing the roof open.
Moisture meter
Confirms wet insulation and decking with a numeric reading. We record before-and-after numbers so you can see the roof actually dried.
Roof inspection drone
Maps ponding water, seam separation, and storm damage across large commercial roofs in minutes, so we can prioritize repairs instead of walking every square foot.
Hot-air welder and seam roller
Bonds TPO membrane patches and seam strips into one continuous sheet. The seam roller presses the weld while it is hot, which is what makes the repair permanent.
Water hose test kit
Applies controlled water to a suspect seam, flashing, or penetration so we can confirm the entry point before we cut anything.
Roof safety harness and ladder stabilizer
Keeps our technicians tied off and the ladder stable on every low-slope roof, which is an OSHA requirement and a basic part of doing the job right.
Heat-welded seam repair
We cut out the failed seam, clean both membrane edges, and weld a new strip of matching TPO with a hot-air welder. This restores the roof to a single sheet rather than relying on a surface coating that fails in a season.
Water test and trace
We isolate the suspect area and run water over it in a controlled pattern, watching the ceiling below for the first sign of moisture. This confirms the entry point before any repair begins, which prevents repeat callbacks.
Infrared moisture mapping
We scan the roof and the ceiling with an infrared thermal imaging camera to map where water has traveled. This is how we find leaks that show up 20 feet from the actual breach.
Manufacturer repair detail
Where your membrane is a Firestone, Carlisle SynTec, GAF, or Tremco system, we follow that manufacturer's published repair detail so your existing warranty stays valid. We photograph the finished weld for your records.
Where this service helps
When to call for TPO roof leak repair
A ceiling tile is stained and soft after a heavy Conroe thunderstorm, and you can see a drip trail on the underside of the deck.
We inspect within the same day, run a water test on the nearest seams and penetrations, and weld the confirmed breach. If the leak is active, we tarp first and weld once the membrane dries. The drip stops the same day, and you get moisture readings showing the deck is drying. Most customers are back to a dry ceiling within 48 hours.
Your commercial building has a rooftop HVAC unit and water appears in the same corner of the stockroom every time it rains hard.
We inspect the curb flashing and the seams radiating from the unit, which is where 8 out of 10 of these leaks start. We rebuild the curb detail and weld a new membrane collar around the unit base. The stockroom stays dry through the next storm, and the repair is documented for your property manager and insurance file.
You bought a Conroe home with a flat-roof addition, and the inspector flagged attic moisture but could not find the source.
We scan the attic and the membrane with an infrared thermal imaging camera to locate the trapped water, then open the suspect seam and repair it with a heat-welded patch. You get a clear answer on where the water was entering, a finished repair, and before-and-after moisture readings you can hand to your real estate agent.
A storm peeled back a section of TPO membrane over your electrical room at 11 p.m. and rain is coming in now.
We dispatch 24/7, tarp the opening to stop water entering, and return the next dry day to weld the membrane back down permanently and replace any wet insulation. No equipment damage overnight, and a permanent repair within 48 hours. You get photos of both the tarp and the final weld.
Local execution
How TPO roof leak repair runs in Conroe
Conroe flat roofs live through a specific cycle: a hot, humid summer that pushes membrane surface temperatures past 150 degrees, then spring and fall storms that drop two inches of rain in under an hour. That expansion and contraction is what opens TPO seams, and it is why we see more seam leaks here than in drier parts of Texas. Most of the buildings we repair are 1990s to 2010s retail centers, warehouses, and home additions with low-slope sections, and many still have original membrane. We work to Montgomery County and Texas building code on every repair, including proper termination heights and drain details. If you need emergency TPO roof leak repair Conroe TX same day, call before noon and we can usually be on the roof that afternoon. Our trucks carry 60-mil TPO membrane, butyl tape, and hot-air welders, so a confirmed seam or boot leak gets fixed on the first visit instead of tarped and rescheduled.
Downtown Conroe (77301)
Older commercial buildings with original TPO and modified bitumen roofs. Seam separation and drain leaks are the most common calls here.
Conroe 77304 corridor
Newer retail and office buildings with white TPO membrane. We see ponding water at low spots and failed HVAC curb flashing after heavy storms.
The Woodlands edge
Home additions and porch roofs with small TPO sections. Wall flashing and termination bar failures drive most of the leak calls.
Willis and 77303
Mixed commercial and residential flat roofs. Vent boot leaks and pipe penetration failures are the most frequent repair we run out here.
Summer surface temps above 150 degrees
Heat cycling expands and contracts the membrane until seams separate. This is the single biggest driver of TPO leaks in Conroe, and it is why we inspect every seam within 20 feet of a confirmed breach.
Afternoon thunderstorms with 2-inch rain rates
Fast, heavy rain finds any open seam or flashing gap immediately. It also overwhelms drains and creates ponding that stresses the membrane for days afterward.
High humidity and attic condensation
Humidity makes it harder to tell a roof leak from condensation on the deck. We use moisture readings and thermal imaging to separate the two before quoting a repair.
Hail and wind events in spring
Hail bruises TPO membrane and wind peels back terminations. We document damage with a HAAG Certified Inspector so your insurance claim has the evidence it needs.
Before and after
What a successful service visit changes.
Retail center seam leak, Conroe 77301
Before
A 12-foot seam on a 1990s TPO roof had separated and was leaking onto a retail display every time it rained. The property manager had two prior patch attempts with roof cement, both of which failed within a month.
After
We cut out the failed seam, welded a new 60-mil TPO strip, and water tested the full run. Moisture readings in the insulation dropped from 28 percent to 11 percent over four days. No leaks through the following storm season.
Maintenance: We recommend a seam inspection each spring before storm season and keeping rooftop traffic off the repaired area. A five-minute visual check after any major hail event catches new damage early.
Vent boot leak, Willis
Before
A cracked vent boot on a small commercial TPO roof was sending water down a pipe and staining a ceiling tile 15 feet away. The owner had assumed the leak was at the wall flashing and was ready to approve a much larger repair.
After
We replaced the boot, added a butyl tape collar, and welded a new TPO skirt around the pipe base. The ceiling dried within a week and the stain stopped growing. Total repair time was under three hours.
Maintenance: Check vent boots and pipe collars once a year, especially after a summer of high UV. A $200 boot replacement prevents a $2,000 ceiling and insulation repair.
Storm-tarped server room, Conroe 77304
Before
A spring storm peeled back 30 feet of TPO membrane over a server room at 11 p.m. Rain was entering the building and the IT rack was at risk. The facilities lead called our 24/7 line.
After
We tarped the opening within two hours and stopped the water. The next dry day we welded the membrane back down, replaced two wet insulation boards, and water tested the repair. Zero equipment damage and no downtime.
Maintenance: After any wind event above 50 mph, walk the roof and check terminations and edges. Catching a lifted edge before the next storm is the cheapest insurance a flat roof has.
Problems we solve
TPO roof problems we fix in Conroe
Flat roofs fail at predictable points. Here are the ones we see most often on Conroe TPO systems, and what happens if they are left alone through another storm season.
Seam separation from heat cycling
A split seam lets water straight into the insulation board. Left through one rainy season, the polyiso soaks, the metal deck rusts, and the repair grows from a weld to a deck replacement. We cut out the failed seam, clean both membrane edges, and hot-air weld a new strip of 60-mil TPO into place. The roof returns to a single continuous sheet, and we photograph the weld so you have proof of the repair.
Vent boot and pipe penetration leaks
The rubber collar on a vent boot cracks after a few Texas summers. Water runs down the pipe and shows up as a ceiling water stain 15 feet away, which is why so many homeowners misdiagnose the source. We replace the boot, add a butyl tape collar, and weld a new TPO skirt around the pipe base. We also check every other penetration within 20 feet while we are up there, since they age at the same rate.
Ponding water at low spots
Standing water for more than 48 hours after a storm stresses seams and grows algae that eats the membrane. It also adds weight to the structure and shortens the life of the whole roof system. We map the low spots with a drone survey, then correct the ones we can with tapered insulation or a new drain detail. Where the slope cannot be fixed economically, we reinforce the seams around the ponding area so the water has nowhere to enter.
Failed wall and curb flashing
Flashing leak at a parapet or HVAC curb lets water behind the membrane, where it travels sideways and shows up far from the actual breach. That makes it one of the hardest leaks to find without thermal imaging. We remove the old termination bar, reseal the counterflashing, and weld a new membrane skirt over the joint. Then we water test the whole run, not just the spot that looked wet, so the fix holds through the next storm.

How much does TPO roof leak repair cost in Conroe TX?
Most TPO roof leak repairs in Conroe run $350 to $1,200 in 2026, with a diagnostic visit around $150 to $250. A single seam weld or pipe boot replacement sits at the low end. Larger repairs that involve insulation replacement, multiple penetrations, or a rooftop unit curb push toward the top. Emergency after-hours work adds a call-out fee. We quote the repair before we start, so you approve the number first.
Who fixes TPO roof leaks in Conroe Texas?
You want a flat-roof contractor who heat-welds TPO membrane rather than a general roofer who only handles shingles. We work single-ply membrane daily and carry 60-mil TPO, seam rollers, and hot-air welders on the truck. Ask any contractor whether they weld or glue, and whether they document moisture readings. If they cannot answer both, keep calling.
Can TPO roof leaks be repaired in the rain in Conroe TX?
Active leaks can be stopped in the rain with a temporary tarp or a peel-and-stick patch, which we do on 24/7 emergency calls. A permanent heat-welded repair needs a dry membrane, so we schedule that weld for the next dry window, usually within 24 to 48 hours. Never let anyone heat-weld over standing water, because the weld will fail.
How long does TPO roof leak repair take in Conroe TX?
A single seam or penetration repair takes two to four hours on site, including the water test and verification. A larger repair with insulation replacement can run a full day. Diagnostic inspection alone is 30 to 60 minutes. We give you a time window when we confirm the appointment and call if anything changes.
