What is included
What a Flat Roof Leak Repair Includes
Every flat roof leak repair we do includes the diagnostic work and the permanent repair, not just a patch over the visible spot. Here is what is covered in a standard job, and what we quote separately if we find it once we are on the roof.
Full Leak Detection
We walk the roof with a moisture meter and infrared camera, then confirm the entry point with a controlled water test. This is included in every job because a repair without a confirmed source is a guess, and guessing costs you money.
Membrane-Matched Repair Materials
Your patch is cut from the same membrane system already on the roof, whether that is EPDM, TPO, or modified bitumen. We carry Firestone, Carlisle SynTec, and GAF materials so the repair bonds correctly and stays under the manufacturer warranty.
Seam and Penetration Sealing
The repair includes resealing the seams and penetrations around the failed area, not just the hole itself. Most flat roof leaks come back because the repair only addressed the visible damage and left the surrounding seams ready to fail next.
Post-Repair Water Test
We re-test the repair before we leave. That means running water over the fixed area and checking the interior for any remaining moisture. You get the result and photos of the before and after so you know the job is done.
Warranty Documentation
You get the workmanship warranty and the material warranty paperwork before we leave the property. If the same repair fails inside the warranty window, we come back and fix it at no charge. That is the difference between a repair and a temporary patch.

Service overview
What Flat Roof Leak Repair in Conroe Really Involves
Flat Roof Leak Repair in Conroe is the process of locating the breach in a low-slope membrane roof and sealing it so water stops entering the building. On an EPDM or TPO roof, that means checking every seam, penetration, and drain edge, because water travels sideways under the membrane before it shows up on your ceiling. We use a moisture meter and an infrared thermal imaging camera to trace the path, then open only the section that is actually failing.
Conroe roofs take a beating. Summer UV bakes the membrane, and the spring storms that roll through Montgomery County push water against seams and flashing that were never meant to hold standing water. That is why we get so many calls for flat roof leak fixing Conroe Texas homeowners and property managers need done before the next round of rain. If you have a ceiling water stain spreading, that is your cue to call.
- Stop Damage Early — A seam separation caught in the first week is a patch and a sealant job. Left through one rainy season, the same leak saturates insulation and rots decking, and the repair cost multiplies. We document the moisture readings before and after so you can see exactly what we stopped.
- Same-Day Emergency Response — When water is dripping into a living room or a storefront, we offer 24/7 flat roof leak repair Conroe TX service and can tarp the roof the same day to stop the water while we schedule the permanent fix. No waiting three days for a callback while buckets fill up.
- Repairs That Match the Membrane — We carry Firestone, Carlisle SynTec, and GAF membrane materials so the patch matches what is already on your roof. A butyl tape and roof cement patch on a TPO roof will fail again within a year. A heat-welded TPO patch done correctly holds for the life of the membrane.
- Clear, Upfront Pricing — You get the price before we start, and it does not change because we found a second seam. Affordable flat roof leak fixing Conroe Texas property owners can budget for means a written number, a scope you understand, and no surprise line items when the invoice arrives.
- We Find It Before We Fix It — Guessing at a flat roof leak wastes your money. We confirm the entry point with a water hose test and thermal imaging before any material comes off the roof, so you pay for the repair that actually solves the problem rather than a patch over the wrong spot.
- Licensed, Insured, and Local — We hold a Texas Roofing License and carry full liability and workers comp coverage. Our crews work Conroe, The Woodlands, and Willis daily, so we know the building stock and the storm patterns that cause most of these leaks in the first place.
- Emergency Flat Roof Leak Repair Conroe TX — Water does not wait for business hours. We run 24/7 emergency flat roof leak repair Conroe TX calls and can tarp a failing roof the same day to stop interior damage while the permanent repair gets scheduled. One call and the bleeding stops.
- Warranty on the Work — Every flat roof leak repair we complete carries a workmanship warranty on top of the manufacturer material warranty. If the same seam fails again inside the warranty window, we come back and make it right at no charge. That is the difference between a repair and a temporary patch.
The service timeline
How Our Flat Roof Leak Repair Process Works
Call and Triage
You call (936) 304-3062 and describe what you are seeing: where the stain is, when it gets worse, whether it started after a storm. We ask enough questions to know if this is an emergency tarp situation or a scheduled repair, and we book the visit accordingly.
On-Site Leak Detection
A technician walks the roof with a moisture meter and an infrared thermal imaging camera. On larger commercial roofs we may fly a roof inspection drone first to cover square footage quickly. This step usually takes 45 to 90 minutes and is when we find the true source.
Water Test and Confirmation
Before we cut anything open, we confirm the leak with a controlled water hose test at the suspected entry point. This is the step that separates a real repair from a guess. We show you the reading and explain what we found in plain terms.
The Repair Itself
We remove the failed section, dry the decking, and install the correct patch material for your membrane. Seams get butyl tape or heat welding depending on the system, and penetrations get a new pipe boot or flashing. Most repairs take two to four hours on site.
Final Test and Walkthrough
We re-test the repair, check the interior for any remaining moisture, and walk you through what we did. You get photos of the before and after, plus a note on what to watch over the next rainy season. Warranty paperwork is left with you before we pull off the driveway.

Tools and Methods We Use on Flat Roofs
Infrared thermal imaging camera
Finds wet insulation under the membrane by reading temperature differences. On large commercial roofs, it maps the full extent of a leak in minutes instead of hours of walking.
Moisture meter
Confirms the presence of moisture in decking and insulation at specific points. We use it before and after the repair so you have a documented reading, not just a visual opinion.
Roof inspection drone
Covers large or hard-to-access flat roofs quickly and safely. It gives us an overview before we send a technician up, which saves time on commercial buildings.
Water hose test kit
Confirms the leak entry point with controlled water before we open the membrane. This is the step that prevents repairing the wrong spot.
Roof safety harness and ladder stabilizer
Keeps our crew safe on low-slope roofs and at the ladder. Safety equipment is not optional on a commercial flat roof, and it is part of every job setup.
Caulking gun and pry bar
Used for sealant application at terminations and for lifting edges to inspect the membrane and decking underneath. Simple tools, but they are what make a clean, lasting repair.
Infrared scan before repair
We scan the roof with a thermal camera before any material comes off. Wet insulation shows up clearly, which tells us exactly how far the repair needs to extend. This prevents both under-repairing and tearing off more roof than necessary.
Controlled water testing
We apply water to the suspected area in a controlled way and watch for the interior response. This confirms the entry point before we commit to a repair location, which is the single biggest factor in getting the fix right the first time.
Manufacturer-spec seam welding
TPO and EPDM seams are repaired according to the membrane manufacturer's published specification, using heat welding or the correct adhesive. Following the spec is what keeps the repair under warranty and ensures it holds through thermal cycling.
Layered repair for modified bitumen
Modified bitumen repairs are built in layers, matching the original roof assembly. We remove the failed plies, dry the deck, and rebuild with new cap sheet so the repair performs like the original roof rather than a surface patch.
Where this service helps
When Conroe Property Owners Call Us
A commercial tenant calls because water is dripping into the sales floor during a storm.
We roll a crew out for emergency tarping the same day to stop the water, then return to make the permanent flat roof leak repair once the roof is dry. The business stays open and the inventory stays dry. The leak is stopped within hours, and the permanent repair is scheduled within a few days. The tenant stops calling and the property manager has documentation for the owner.
A homeowner notices a ceiling stain spreading over the garage after a heavy rain.
We run a full leak detection on the flat garage roof, find the failed seam or flashing, and repair it with matching membrane material. We also check the attic for moisture while we are there. The stain stops spreading, the attic dries out, and the homeowner has photos and a warranty on the repair. No more guessing every time it rains.
A property manager needs flat roof leak fixing Conroe TX buildings require before the insurance inspection.
We inspect the full roof, document every issue with photos and moisture readings, and complete the repairs needed to pass the inspection. The report is formatted for the insurance file. The building passes inspection, the insurance claim is supported by real documentation, and the roof is watertight going into storm season.
An older building has a modified bitumen roof that has been patched multiple times.
We assess whether the roof can be repaired or needs a section replacement. If repair makes sense, we remove the failed layers and rebuild the plies to match the original assembly. The customer gets a straight answer on repair versus replacement, and the repair we do holds because it addresses the failed layer instead of covering it up.
Local execution
How Flat Roof Leak Repair Runs in Conroe
Conroe sits in Montgomery County where the climate swings hard: summer roof surface temperatures push past 150 degrees, and spring storms drop heavy rain in short windows. That cycle of expansion and contraction is what opens seams on flat roofs here, and it is why seam separation is the most common leak we find. Older commercial buildings along the I-45 corridor often have modified bitumen or built-up roofs that are 20-plus years old, while newer construction leans toward TPO and EPDM. We match the repair to the system that is actually on the roof. If you need flat roof leak fixing Conroe Texas property owners can count on before storm season, we schedule those visits ahead of the rush. For urgent calls, our 24/7 flat roof leak repair Conroe TX line is answered day or night, and we can usually tarp the same day.
River Plantation
Many homes here have flat roof sections over additions and garages. The mature trees drop debris that clogs drains and causes ponding, which is a common source of leaks we repair in this neighborhood.
Downtown Conroe
Older commercial buildings downtown often have modified bitumen or built-up roofs. These systems need layered repairs rather than single-ply patches, and we stock the materials to match them.
April Sound
Homes around the lake see more humidity and wind-driven rain, which stresses flashing at roof-to-wall transitions. We check those transitions on every flat roof call in this area.
Panorama Village
The mix of older homes and commercial buildings here means we see both residential and commercial flat roofs on the same street. We carry materials for both so we are not making a second trip.
Summer UV exposure above 150 degrees surface temperature
UV degrades sealant and membrane faster on a flat roof than on a pitched one. Sealant at penetrations needs refreshing more often here, and we check it on every repair visit.
Heavy spring rain in short windows
Water stacks up on a flat roof faster than the drains can handle it during a Conroe storm. That is when failing seams show themselves, and it is why we get a spike in emergency calls each spring.
Clay soil movement under older foundations
Soil movement can shift the roof structure slightly over time, which stresses seams and flashing. On older Conroe buildings, we check for this when a leak keeps returning after repair.
Before and after
What a successful service visit changes.
TPO Seam Leak on a Retail Building
Before
A retail tenant had water staining a ceiling tile about 15 feet from any visible roof damage. Two previous patch attempts had failed. The roof was a 15-year-old TPO membrane with a separated seam that was letting water travel under the surface.
After
We confirmed the seam with a water test, cut back the failed section, and heat-welded a new TPO patch to manufacturer spec. The repair took three hours and the moisture meter read dry at the follow-up. No leaks through the next two storm seasons.
Maintenance: We recommended an annual seam inspection each spring before storm season. Seam checks are inexpensive and catch separation before it becomes a leak.
EPDM Vent Boot Leak in a Home Garage
Before
A homeowner in The Woodlands had a persistent drip onto a garage ceiling after every rain. The flat garage roof was EPDM, and the pipe boot around the plumbing vent had cracked from UV exposure. Water was running down the pipe and into the ceiling.
After
We replaced the boot with a new EPDM-compatible boot, resealed the penetration, and re-tested with water. The repair took under two hours. The ceiling dried out and the stain stopped growing within a week.
Maintenance: Check the boot and sealant at every roof penetration once a year. A $30 boot replacement prevents a ceiling repair that runs into the hundreds.
Modified Bitumen Ponding Leak in Downtown Conroe
Before
An older commercial building downtown had standing water after every storm and a leak that had been patched three times. The drain was partially clogged and the cap sheet around it had failed. Water was entering the building at the wall base.
After
We cleared the drain, removed the failed cap sheet, and rebuilt the plies around the drain with new modified bitumen. We also corrected the slope at the low spot. The roof now sheds water, and the interior stayed dry through the next rainy season.
Maintenance: Clear the drains before storm season and after any heavy leaf drop. Standing water is the leading cause of flat roof failure, and drain clearing is the cheapest preventive step.
Problems we solve
Flat Roof Leak Problems We Solve in Conroe
Most flat roof leaks we see in Conroe fall into a handful of categories. Knowing which one you have helps you understand what the repair will involve.
Ceiling water stain that keeps coming back
A recurring stain means the leak was never actually fixed, just painted over. Water keeps soaking the insulation and decking, and the damage spreads every time it rains. We trace the stain back to the roof entry point with thermal imaging and a water test, then repair the actual source. No more painting over the symptom. The stain stops growing because the water stops entering.
Seam separation on an aging flat roof
Seams open up as the membrane expands and contracts through Conroe's temperature swings. Once a seam separates, water gets under the membrane and travels, so the leak shows up far from the actual failure. We re-weld or re-tape the seam according to the membrane manufacturer's spec. A proper seam repair with the right equipment holds through the next decade of expansion and contraction, not just the next rain.
Water coming in around a vent or pipe boot
Penetrations are the weakest point on any flat roof. A cracked pipe boot lets water straight into the attic or ceiling cavity, and it often goes unnoticed until the stain is large. We replace the boot and reseal the penetration with membrane-compatible material. This is usually the fastest and least expensive flat roof leak repair we do, and it solves the problem completely.
Ponding water after every storm
Standing water finds every weak point in the membrane and accelerates the failure. It also adds weight to the roof structure and shortens the life of the whole roof system. We identify why the water is ponding, whether it is a clogged drain, a low spot in the deck, or a failed taper. Then we repair the leak and correct the drainage so the water sheds instead of sitting.

How much does flat roof leak repair cost in Conroe TX?
Most flat roof leak repairs in Conroe run $350 to $1,200 in 2026, depending on roof access, membrane type, and how much wet insulation has to come out. A simple seam patch sits at the low end; a repair that involves removing saturated decking and replacing a section of TPO or EPDM lands higher. We give you the number before we start.
Who fixes flat roof leaks in Conroe Texas?
Roof Leak Repair Conroe Pros fixes flat roof leaks across Conroe and Montgomery County, and we handle EPDM, TPO, modified bitumen, and built-up roofs. Not every roofer works on low-slope membranes, so ask before you book. We are licensed in Texas, insured, and carry the manufacturer credentials to keep your material warranty intact.
Can flat roof leaks be repaired in the rain in Conroe TX?
No, a permanent flat roof repair cannot be done in active rain. Water prevents sealants and heat-welded seams from bonding correctly. What we can do is tarp the roof in the rain to stop the water, then return when the surface is dry to make the permanent repair. That is why we run 24/7 emergency tarping calls.
How long does flat roof leak repair take in Conroe TX?
Most flat roof leak repairs take two to four hours on site once we have confirmed the source. The diagnostic step adds 45 to 90 minutes. Larger commercial roofs or repairs that involve removing wet insulation and replacing decking can stretch to a full day. We tell you the expected window when we book the job.
