What is included
What Our Chimney Flashing Repair Covers
Every flashing repair includes the inspection, the rebuild and the water test. What changes from job to job is how much shingle work and decking repair the chimney needs once we open it up. We quote that separately, with photos, before we do it.
Full Chimney Flashing Inspection
We walk the roof and the attic side, photograph the flashing, and check the decking with a moisture meter. You get a written scope and a fixed price before any material is ordered.
New Step and Counter-Flashing
Failed galvanized flashing comes out and new metal goes in, woven into each shingle course. Counter-flashing is cut into a reglet in the mortar and sealed with polyurethane roof sealant rated for Texas sun.
Shingle Reweave
We cut back the shingles around the chase and reweave new courses into the existing roof, matching the profile and color. This keeps the manufacturer warranty intact and the repair invisible from the ground.
Sealant and Membrane Detail
Behind the metal we install butyl tape or a self-adhered membrane at the chimney base, then seal the termination with Sika or Henry Company sealant. That backup layer is what stops wind-driven rain in a storm.
Water Hose Test
A 15 to 20 minute water test on the chimney confirms the repair holds before we pack up. If a drop appears on the attic side, we keep working until it runs dry.
Cleanup and Warranty
We magnet-sweep for nails, haul off the old flashing, and leave you the warranty terms in writing along with photos of the finished repair.

Service overview
What Chimney Flashing Repair Conroe TX Really Involves
Chimney Flashing Repair Conroe TX is roof work that rebuilds the water-shedding connection between your masonry chimney and the shingles around it. That connection is a layered system: step flashing woven into each course of shingles, counter-flashing cut into the chimney mortar, and a sealant or membrane behind it all. When one layer fails, water runs down the chimney face, under the shingles and into the attic. We pull the failed pieces, inspect the decking for rot, and rebuild the flashing so each layer overlaps the one below it.
Most Conroe flashing failures we see are rust, not age. Galvanized step flashing pits out after years of humid summers and hard UV, and the sealant at the chimney base cracks within a few seasons. Homeowners in 77301 and 77304 often call after a stained ceiling appears in a hallway closet, weeks after the actual leak started. If you have been searching for chimney flashing repair in Conroe TX near me, we run 24/7 chimney flashing repair Conroe TX calls for active leaks and can tarp a chimney chase the same day.
- Stops Repeat Ceiling Stains — Water that enters at the chimney usually tracks along a rafter before it drips. We seal the entry point, then run a water hose test kit to confirm the stain stops growing. Most active leaks are stopped in a single visit, and you get photos of the repair before we close it up.
- Protects Decking and Framing — A slow flashing leak rots the roof deck and the chimney framing behind the siding. Catching it early keeps the job to flashing and a patch of decking instead of a full tear-off around the chase. We probe the deck with a moisture meter before we quote anything.
- Code-Correct on Resale — Chimney flashing replacement Conroe Texas done to code passes a TREC inspection without a second trip. We install layered step and counter-flashing that meets current roof code, which matters when you sell and the buyer's inspector walks the roof.
- Handles Storm Season — Hail damage and wind-driven rain push water sideways into chimney seams that held fine all summer. After a storm, we inspect the flashing, drip edge and shingle damage together so one visit covers the whole roofline instead of three separate call-outs.
- Same-Day Leak Response — Active leaks get priority. Call before noon and we aim to have a roofer on your roof the same day, with emergency tarping available if the chimney chase is taking on water. We work 24/7 during storm events across Montgomery County.
- Written Price Before Work — You get a fixed price for the flashing repair before we cut a shingle. If we open the chase and find rotted decking, we show you the wood and quote the added repair before touching it. No surprise line items at the end.
- Flashing and Shingles Together — A Conroe chimney flashing repair service is only as good as the shingles it ties into. Because we install GAF and CertainTeed systems, we can reweave the surrounding courses and keep the manufacturer warranty intact instead of voiding it with a patch.
- Workmanship Warranty — Our flashing labor carries a workmanship warranty on top of the material warranty. If the same chimney leaks again at the same seam, we come back and make it right. That is the difference between a $300 patch and a repair that holds.
The service timeline
How Our Flashing Repair Process Runs
Leak Interview
We start inside, not on the roof. You show us the stain, and we ask when it appears, which wind direction brings it, and whether the fireplace has been used. That conversation narrows the leak to the chimney flashing, a vent boot or a valley before anyone climbs a ladder.
Roof and Attic Inspection
A roofer harnesses up and walks the chimney chase while a second tech checks the attic side with a moisture meter and infrared thermal imaging camera. We photograph rusted step flashing, separated counter-flashing and any soft decking. You see the pictures before we quote.
Flashing Rebuild
We cut back the shingles around the chase, remove the failed flashing, and install new step flashing woven into each course. Counter-flashing goes into a reglet cut in the mortar, sealed with polyurethane roof sealant. A typical chimney takes two to four hours.
Water Test
Before we leave, we run a water hose test kit on the chimney for 15 to 20 minutes while a tech watches the attic side. If a drop shows up, we keep working. No repair is signed off until the test runs dry.
Cleanup and Walkthrough
We magnet-sweep the yard for nails, haul off old flashing, and walk you through the repair with photos. You get the warranty terms in writing and a note on what to watch for after the next heavy rain.

Tools and Methods We Use on Chimneys
Moisture meter
Reads moisture content in decking and framing around the chimney so we know how far the water traveled before we quote.
Infrared thermal imaging camera
Shows wet insulation and framing behind the chimney chase without cutting into the ceiling.
Roof inspection drone
Documents chimney flashing and surrounding shingles on steep or tall roofs before we send a roofer up.
Water hose test kit
Runs a controlled 15 to 20 minute water test on the finished flashing while we watch the attic side.
Pry bar and caulking gun
Lifts shingle courses without breaking tabs and lays a clean, uniform bead of roof sealant at the termination.
Ladder stabilizer and roof safety harness
Keeps the crew anchored and the ladder steady on two-story Conroe homes with steep pitches.
Roofing nail gun
Re-secures shingles and flashing with the correct nail pattern and depth so the repair meets code.
Layered step and counter-flashing
We install step flashing woven into each shingle course, then counter-flashing cut into a reglet in the mortar. Each layer overlaps the one below so water sheds outward instead of sitting against the chimney.
NRCA flashing standards
Our flashing details follow NRCA published standards for chimney and wall flashing, which is what a TREC inspector checks on a resale inspection.
Water hose verification
No flashing repair is signed off until a controlled water test runs dry on the attic side. It is the only way to know the repair holds before the next storm tests it for you.
Manufacturer-matched systems
We pair flashing with GAF, Owens Corning or CertainTeed shingle systems so the repair stays inside the manufacturer warranty instead of voiding it.
Where this service helps
When to Call for Chimney Flashing Work
A ceiling stain appears in the same spot after every heavy rain in Conroe.
We inspect the chimney flashing first, since repeat stains in one location usually mean one entry point. A moisture meter confirms the wet path, and we rebuild the flashing if that is the source. The stain stops growing after the next storm, and you have photos showing exactly where the water was getting in.
Water is actively running down the chimney during a storm and the attic is taking on water.
We dispatch for emergency chimney flashing repair Conroe TX same day and tarp the chase to stop the intrusion. Once the roof dries, we return for the permanent flashing repair. The active leak stops the same day, and the permanent repair is scheduled within 24 to 48 hours.
You are selling a Conroe home and the buyer's inspector flagged the chimney flashing.
We inspect the flagged flashing, document the condition with photos, and quote the repair to code. If the flashing is serviceable, we say so in writing so the deal does not stall. A clear repair quote or a clean inspection letter, either of which keeps the closing on track.
Hail or wind damage hit the roof and the chimney flashing looks bent or lifted.
We inspect the flashing alongside the shingles and drip edge, since storm damage rarely stops at one component. A HAAG Certified Inspector documents the damage for your insurance claim. One inspection covers the whole roofline, and the flashing is repaired or replaced with the storm claim.
Local execution
How Chimney Flashing Repair Runs in Conroe
Conroe sits in a pocket of East Texas that gets heavy spring rain, hard summer UV and the occasional freeze. That cycle is rough on flashing. Galvanized metal pits faster here than in drier climates, and sealant at the chimney base cracks within three or four summers. Brick chimneys on older homes in 77301 and 77303 often have counter-flashing that was never cut into a reglet, just caulked to the face, which is why they leak in wind-driven rain. Newer builds out toward 77384 and 77305 usually have factory-built chases with a different flashing detail and a plastic cap that cracks. We adjust the repair to the chimney type instead of using one detail everywhere. If you need affordable chimney flashing replacement Conroe Texas work done before the next front, we inspect the chase, quote a fixed price and schedule the repair, usually within a few days. We also check the drip edge and vent boots while we are up there, since a second leak is cheaper to fix in the same visit.
Downtown Conroe (77301)
Older brick homes with masonry chimneys where counter-flashing is often caulked rather than cut into the mortar.
Conroe 77304
Mix of 1990s and 2000s builds with factory-built chases that develop cracked caps and failed sealant at the base.
The Woodlands edge (77384)
Larger two-story homes with steep pitches where drone documentation saves a risky climb.
Willis and Montgomery
Rural properties with metal and tile roofs that need different chimney flashing details than shingle.
Spring gully-washers and wind-driven rain
Water pushes sideways into chimney seams that hold fine in a straight rain. We cut counter-flashing into the mortar so wind-driven rain cannot get behind it.
Summer UV and heat cycling
Sealant shrinks and cracks faster here than in cooler climates. We use polyurethane or Sika sealant rated for roof movement instead of basic caulk.
Occasional hard freezes
Water trapped behind flashing expands when it freezes and opens the seam wider. A dry, well-layered flashing detail is what prevents that damage.
Hail season
Hail dents and lifts flashing and shingles around the chase. We inspect both after a storm and document damage for insurance when needed.
Before and after
What a successful service visit changes.
Rusted Step Flashing on a 77304 Ranch
Before
A homeowner in 77304 had a ceiling stain that returned after every rain. The step flashing on the chimney was rusted through in two courses, and the decking under it was soft across about two square feet.
After
We replaced the step flashing, cut out the soft decking and rewove three courses of matching shingles. The water hose test ran dry for 20 minutes, and the stain has not grown through two storm seasons.
Maintenance: We recommend checking the chimney flashing after each hail season and keeping the chimney cap clear of debris so water does not back up behind the flashing.
Counter-Flashing Gap on a Brick Chimney
Before
A two-story brick home near The Woodlands leaked only in wind-driven rain. The counter-flashing had been caulked to the chimney face years earlier and the caulk had failed, leaving a gap along the mortar joint.
After
We cut a new reglet into the mortar, installed new counter-flashing and sealed it with polyurethane. The repair took about four hours, and the attic stayed dry through the next two storms.
Maintenance: An annual visual check of the mortar joint and a fresh bead of sealant every few years keeps that reglet watertight.
Storm-Damaged Flashing in Willis
Before
A hail storm lifted the flashing and dented the shingles around a chimney in Willis. Water was running down the chase into the attic during the next rain, and the homeowner called for emergency tarping.
After
We tarped the chase the same day, then replaced the flashing and the damaged shingles two days later. The repair was documented for the insurance claim, and the attic dried out without mold.
Maintenance: After any hail event, have the flashing and shingles inspected together; a lifted flashing edge is easy to miss from the ground.
Problems we solve
Chimney Leak Problems We Fix in Conroe
Most chimney leaks we see fall into a handful of patterns. Knowing which one you have tells you how big the repair is before anyone climbs the roof.
Rusted step flashing under the shingles
Rust pits through the metal, letting water run under the shingle courses and into the deck. By the time it shows on the ceiling, the decking around the chase is often soft. We remove the rusted step flashing, probe the deck with a moisture meter, and install new metal woven into each course. If the deck is soft, we replace that section before the new flashing goes down.
Counter-flashing pulled away from the brick
A gap at the mortar joint lets water run straight down the chimney face and behind the flashing. It is the most common cause of a chimney leak that only shows up in wind-driven rain. We cut a new reglet in the mortar, set new counter-flashing and seal it with polyurethane sealant. That gives the flashing a mechanical hold instead of relying on old caulk.
Cracked sealant at the chimney base
Sealant shrinks and cracks within a few summers of Texas heat. Once it opens, water sits against the flashing and rust starts. We strip the old sealant, clean the joint and apply a fresh bead of roof sealant rated for movement. On a flashing replacement Conroe Texas job, this is part of the standard rebuild, not an add-on.
Water tracking to a ceiling stain away from the chimney
Water follows framing, so the stain can appear in a hallway or closet far from the actual leak. Homeowners often pay for the wrong repair first. We use a moisture meter and infrared thermal imaging camera to trace the water path back to the chimney before quoting. That is how we avoid charging you for shingles that were never the problem.

How much does chimney flashing repair cost in Conroe TX?
Most chimney flashing repairs in Conroe run $350 to $900 in 2026, with full replacement at the higher end. Price depends on chimney height, whether the counter-flashing has to be cut into masonry, and how much shingle work is needed to reweave the courses. A simple reseal and step-flashing reset sits near the bottom of that range. We quote a fixed price after the roof inspection, and the estimate is free.

We schedule a half-day window so you are not waiting around, and we do not leave until the water hose test runs dry on the attic side.
