What is included
What Our Modified Bitumen Roof Leak Repair in Conroe Includes
Every repair starts with a full inspection and ends with a water test. Here is what is covered in a standard mod bit roof leak fixing Conroe job. If your roof needs decking replacement or a full section re-cover, we will tell you before we start and price it separately.
Full Roof Inspection
We walk the roof, check seams, flashing, penetrations and drains, and use a moisture meter and infrared camera to find hidden wet areas. You get photos of every problem we find, not just a verbal description.
Leak Source Diagnosis
We trace the water path from the interior stain back to the roof entry point. That may involve a water hose test kit on suspect areas. You get a clear explanation of what failed and why before any repair work begins.
Membrane Repair or Replacement
We cut out failed membrane, dry the deck, and install new modified bitumen that matches your existing system. Seams are heat-welded or cold-adhered, and the repair is tied into the field so water cannot get under the edges.
Flashing and Sealant Work
Failed flashing and dried sealant are re-done with butyl tape and roof sealant rated for Texas heat. This includes wall flashing, pipe boots, drip edge and any penetration that is letting water in.
Water Test and Photo Report
We water-test the repaired area and check inside for moisture before we leave. You get a photo report of the work, a warranty document, and a note on what to watch for next season. If you are off-site, we send it all by text or email.

Service overview
What Modified Bitumen Roof Leak Repair in Conroe Actually Involves
Modified Bitumen Roof Leak Repair in Conroe is the process of locating and sealing water intrusion on mod bit membrane roofs, which are the asphalt-based rolled membranes common on flat and low-slope commercial and residential buildings. We start by finding the actual entry point, not just the wet stain. Water travels along decking, so a leak showing up over your kitchen may start 20 feet away at a seam, a pipe boot or a roof penetration. We dry the area, cut back failed membrane, then re-lay and heat-weld or cold-adhere new material so the repair ties into the existing field.
Conroe sits in a humid subtropical zone with 45 to 50 inches of rain a year, plus hail and summer heat that pushes roof surface temps past 150 degrees. That cycle of bake-and-soak is brutal on mod bit. Seams separate, blisters form, and flashing pulls away from walls. When you need affordable mod bit roof leak fixing Conroe Texas property owners can count on, we handle everything from a single seam to a full section replacement. If you have been searching for modified bitumen roof leak repair in Conroe TX near me, we are local and we answer the phone.
- Leak Found, Not Guessed — We use a moisture meter and infrared thermal imaging camera to trace water back to its entry point. That means we repair the actual source, not the ceiling stain. Most misdiagnosed mod bit leaks we re-inspect were patched three or four times in the wrong spot before we arrived.
- Repairs That Hold Through Storm Season — We heat-weld or cold-adhere membrane patches and reinforce them with butyl tape and roof sealant rated for Texas heat. A properly tied-in repair survives hail, 60 mph gusts and the 150-degree surface temps a Conroe July throws at it.
- Emergency Response When It Is Pouring — Water coming in at 2 a.m. does not wait for business hours. Our emergency modified bitumen roof leak repair Conroe TX line stays open 24/7, and we can tarp the roof to stop the bleeding until we can make a permanent fix in dry conditions.
- Flat Pricing Before We Start — You get a written number before any work begins. Most single-seam or flashing repairs land between $350 and $900 in 2026, and we tell you that up front. No surprise add-ons, no hourly meter running while we figure it out.
- We Find the Real Source — Water on a mod bit roof can travel 20 feet or more before it shows up inside. We use moisture meters and infrared thermal imaging to trace it back. That is why our repairs hold. We are not patching the stain on your ceiling; we are sealing the seam that caused it.
- 24/7 Emergency Response — Storms do not check the clock. Our emergency modified bitumen roof leak repair Conroe TX service runs around the clock. We tarp active leaks to stop interior damage, then return in dry weather to make the permanent repair. Same-day service is available for most calls before noon.
- Warrantied Workmanship — Every mod bit roof leak fixing Conroe job carries a workmanship warranty on top of the membrane manufacturer warranty. If our repair fails within the warranty window, we come back and make it right at no charge. We put that in writing on your invoice.
- Commercial and Residential — We repair mod bit on both. That includes Conroe modified bitumen roof leak repair service for strip centers, warehouses and office buildings, plus residential flat-roof sections on garages, additions and patio covers. Same crew, same standards, whether the roof is 400 square feet or 40,000.
The service timeline
Our Modified Bitumen Leak Repair Process, Step by Step
Call and Schedule
You call (936) 304-3062 and describe what you are seeing: ceiling stain, dripping vent, water in the attic. We ask a few questions, then book a same-day or next-morning inspection. For active leaks, we dispatch immediately. You get a text when the tech is on the way.
Roof Inspection
A HAAG Certified Inspector walks the roof with a moisture meter and infrared thermal imaging camera. We check seams, flashing, pipe boots, drip edge and penetrations. On larger buildings we fly a roof inspection drone to cover the full field without walking every square foot. This takes 30 to 60 minutes.
Leak Source Confirmed
We show you photos of the failure and explain what caused it. If a water hose test kit is needed to confirm the path, we run it. You approve the repair scope and the flat price before we touch anything. No work starts without your go-ahead.
Repair and Seal
We cut back the failed membrane, dry the deck, and install new modified bitumen. Seams get heat-welded or cold-adhered, flashing gets re-secured, and every penetration gets fresh roof sealant and butyl tape. Most repairs take two to five hours. Larger section replacements run a full day.
Water Test and Walkthrough
We flood-test or hose-test the repaired area and check inside for any remaining moisture. Then we walk the roof with you or send a photo report if you are off-site. You get a warranty document and a maintenance note telling you what to watch for next season.

Tools and Methods We Use for Mod Bit Leak Repair
Moisture Meter
Reads moisture content in decking, insulation and drywall so we know exactly how far the water has spread. This tells us whether a spot repair is enough or whether a larger section needs to come out.
Infrared Thermal Imaging Camera
Finds wet insulation under the membrane by temperature difference. On large commercial roofs, this is the fastest way to map the full extent of a leak without cutting test holes.
Roof Inspection Drone
Covers large or steep roof areas safely and quickly. We use it to document the full roof condition and to check areas that are hard to walk, like tall parapets and steep transitions.
Water Hose Test Kit
Confirms the leak source by applying controlled water to suspect areas. If we think a seam is the problem, we test it before and after the repair to prove the fix works.
Roof Safety Harness and Ladder Stabilizer
Keeps our crews safe on low-slope and steep roofs. OSHA-compliant fall protection is standard on every job, and the ladder stabilizer prevents damage to gutters and siding.
Caulking Gun and Pry Bar
For precise sealant application and for lifting failed membrane and flashing without damaging the surrounding roof. Small tools, but they make the difference between a clean repair and a mess.
Heat-Welded Seam Repair
We use a heat welder to fuse new membrane to the existing mod bit field. Heat-welded seams are stronger than adhesive seams and are the standard for Firestone and Carlisle SynTec systems. This is our go-to method for seam separation on Conroe roofs.
Cold-Adhesive Membrane Patching
When heat welding is not safe or practical, we use cold-applied adhesive to bond the patch. This method works well on smaller repairs and on roofs where open flame is not allowed. The bond is strong and the repair is watertight.
Infrared Moisture Mapping
We scan the roof with an infrared camera to find wet insulation before we cut. This lets us target the repair precisely and avoid replacing dry material. It is the same method HAAG Certified Inspectors use for storm damage documentation.
Water Hose Verification
After every repair, we apply controlled water to the area and check inside for moisture. If the repair holds, you know it before we pack up. If it does not, we find out on our time, not yours.
Where this service helps
When Conroe Property Owners Call Us for Mod Bit Leak Fixing
A commercial building with a mod bit roof is leaking into a tenant space during business hours.
We dispatch for emergency tarping to stop the water, then return in dry weather to make the permanent repair. We can work after hours or on weekends so your tenants are not disrupted, and we document everything for your property file. Tenant stays open, water damage stops, and the repair is done without a business interruption claim.
A homeowner notices a ceiling stain under a flat-roof garage or addition after a storm.
We inspect the mod bit section, find the failed seam or flashing, and repair it in a single visit. Most residential mod bit repairs take two to four hours and are done the same day you call. The leak is fixed, the ceiling can dry out, and you avoid mold and decking rot.
A property manager has patched the same mod bit leak three times and it keeps coming back.
We use infrared thermal imaging to map the actual water path, which is often 15 to 20 feet from the visible stain. We repair the real source instead of the symptom, then water-test to confirm it is sealed. The recurring leak is finally fixed, and you stop paying for repeat call-outs.
A hail storm has damaged a mod bit roof and the insurance adjuster needs documentation.
Our HAAG Certified Inspector documents the damage with photos, moisture readings and a written report that meets insurance standards. We can also tarp the roof if it is actively leaking while the claim is processed. You get a documented claim and a repaired roof, without fighting the insurance company on your own.

How Mod Bit Roof Leak Repair Runs in Conroe, Texas
Conroe is hard on mod bit roofs. We get 45 to 50 inches of rain a year, summer surface temperatures that hit 150 degrees, and hail storms that crack membrane and open seams. The humidity stays high enough that wet insulation does not dry out on its own, so a small leak can turn into a rotted deck in a few months. Most of the mod bit roofs we repair are on commercial buildings, garages, additions and patio covers built between the 1980s and 2000s. Many are original and well past their service life, which is why we see so many seam and flashing failures. We work with Firestone, Carlisle SynTec, Tremco and Henry Company materials so repairs match what is already on your roof. If you need emergency modified bitumen roof leak repair Conroe TX same day, we run 24/7 and can tarp the roof to stop the water until conditions allow a permanent fix. We also serve The Woodlands, Spring, Willis, Montgomery, Magnolia, Tomball, Shenandoah and Oak Ridge North.
River Plantation
Many homes here have flat-roof garages and additions with mod bit membrane that are now 20 to 30 years old. Seam separation and flashing failures are the most common calls we get from this area.
April Sound
Larger custom homes with low-slope sections and complex roof transitions. Mod bit leaks here often start at wall flashing or where a flat section meets a shingle field.
Downtown Conroe
Older commercial buildings with original mod bit or built-up roofs. We do a lot of seam repair and flashing rebuilds on these buildings because full replacement is not always in the budget.
Wedgewood
Established residential neighborhood with a mix of roof types. We frequently repair mod bit patio covers and garage roofs here after spring and fall storms.
Summer surface temperatures above 150 degrees
Heat softens mod bit membrane and stresses seams. Over time, seams separate and blisters form. We use heat-rated sealants and proper welding techniques so repairs hold through the worst of a Conroe summer.
45 to 50 inches of annual rainfall
Constant wet-dry cycling works water into every small gap. A pinhole leak becomes a saturated insulation panel fast. We water-test every repair to make sure it sheds water the way it should.
Hail storms in spring and fall
Hail cracks membrane and knocks granules loose, which exposes the asphalt to UV. After a storm, we inspect for hail damage and document it for insurance claims if needed.
High humidity year-round
Wet insulation does not dry out on its own in Conroe. Once water gets in, it stays. That is why we use moisture meters to check the full extent of the leak, not just the visible stain.
Before and after
What a successful service visit changes.
Commercial Seam Leak Stopped in One Visit
Before
A 12,000-square-foot strip center had water dripping into two tenant spaces every time it rained. Two previous contractors had patched the ceiling side and the leak kept returning. The actual failure was a 14-foot separated seam on the far side of the roof.
After
We heat-welded the failed seam, reinforced it with butyl tape, and water-tested the area. The leak stopped completely. The repair took four hours and cost less than $1,200, compared to a $28,000 full roof replacement quote.
Maintenance: We recommended an annual seam inspection each spring before storm season. Catching seam separation early keeps a $1,200 repair from becoming a $28,000 replacement.
Residential Garage Roof Leak Fixed Same Day
Before
A homeowner in River Plantation had water dripping onto stored tools and boxes in the garage. The mod bit roof was 22 years old and had a failed pipe boot plus a cracked sealant joint at the wall flashing.
After
We replaced the pipe boot, re-sealed the wall flashing, and water-tested both areas. The repair took three hours and cost $480. The garage stayed dry through the next two rainstorms.
Maintenance: We told the homeowner to check the pipe boot and flashing sealant every fall. Those two details cause most mod bit leaks on residential roofs.
Church Fellowship Hall Membrane Replaced
Before
A Montgomery County church had a 6,000-square-foot mod bit roof leaking into a fellowship hall. Infrared scanning showed wet insulation across two large sections. The roof had been patched repeatedly over three years with no lasting result.
After
We removed and replaced two sections of membrane, re-flashed the perimeter, and installed new pipe boots. The project took two days and cost $9,400, which was thousands less than a full replacement. The hall has been dry since.
Maintenance: We set them up on a twice-a-year inspection schedule, once before storm season and once after. That keeps small issues from turning into another two-section replacement.
Problems we solve
Mod Bit Roof Leak Problems We Solve in Conroe
Mod bit roofs fail in a handful of predictable ways. If you recognize any of these, the leak is not going to fix itself, and every rainstorm makes the damage worse.
Water staining the ceiling after every heavy rain
The stain spreads, drywall sags, and insulation stays wet. Mold can start within 48 hours, and rotted decking turns a $600 repair into a $4,000 tear-off. We trace the stain back to the roof entry point, repair the failed seam or flashing, and water-test the fix. You get a dry ceiling and a documented repair that stops the cycle instead of hiding the stain.
Separated seams on a flat mod bit roof
Seam separation is the number one cause of mod bit leaks. Water gets under the membrane, saturates the insulation, and spreads sideways until the whole section is compromised. We re-weld or re-adhere the failed seams, reinforce them with butyl tape, and check every other seam on the roof for early signs of failure. If multiple seams are going, we can re-seam the whole section.
Blisters and bubbles in the membrane
Blisters trap moisture and heat, and they rupture under foot traffic or hail. Once a blister opens, water goes straight into the roof system and the leak shows up inside. We cut out the blister, dry the area, and re-lay new membrane with a proper bond. We also check the surrounding field for other blisters so you are not calling us back next month for the same problem.
Flashing pulling away from walls or curbs
Failed flashing lets water run straight down the wall and into the building. It often shows up as a ceiling stain far from the actual leak, which is why so many DIY patches miss the mark. We rebuild the flashing detail with new membrane, counter-flashing and sealant, then water-test it. This is one of the most common mod bit repairs we do in Conroe, especially on older commercial buildings.

How much does modified bitumen roof leak repair cost in Conroe TX?
Most repairs run $350 to $900 in 2026, depending on access, roof height and how much membrane has to be replaced. A single seam or pipe boot repair sits at the low end. A larger section replacement with new flashing can reach $1,800 or more. We give you a flat price before work starts, so there is no hourly surprise.

Call (936) 304-3062 and we will schedule an inspection.
Can modified bitumen roof leaks be repaired in the rain in Conroe TX?
Active leaks can be stopped in the rain with emergency tarping, but permanent membrane repairs need dry conditions. Heat-welding and cold-adhesive both require a dry surface to bond correctly. If it is pouring, we tarp the roof to stop interior damage, then return when the weather clears to make the permanent repair, usually within 24 to 48 hours.
How long does modified bitumen roof leak repair take in Conroe TX?
A single seam or flashing repair takes two to four hours. A larger section replacement runs six to eight hours, and a full roof section on a commercial building can take one to two days. We tell you the expected timeframe when you approve the scope, and we do not leave until the repair passes a water test.
