Trusted Roof Repair for Houston Homeowners
Roof repair in Houston, TX typically costs between $350 and $1,500 for most residential fixes, with minor shingle work starting around $275 and full sectional replacements running higher depending on decking and underlayment condition. The Gulf Coast climate punishes roofs year-round: summer heat bakes shingles until they crack, afternoon thunderstorms hammer flashing, and hurricane-season winds lift entire sections if the decking has any rot. Since 2000, Brennan Roofing Co Houston has operated under the Garrison Standard: a written price before any work starts, background-checked uniformed technicians on every job, and a 365-Day Done Right Promise in writing. If you need roof repair in Houston, call (940) 461-8481 and you’ll speak to a live person, not an automated system.
Roof Leak Repair
Roof Leak Repair in Houston usually costs between $300 and $900 depending on whether the problem is a single damaged shingle, a failed piece of flashing, or deteriorated decking beneath the surface. A leak is rarely where the water shows up; water travels along rafters and underlayment before it finds a drywall seam to stain. Our technicians trace the water path from the interior stain back to the actual entry point on the roof surface, then replace the failed materials and verify the fix with a water test before we call the job done. Every repair is covered by the 365-Day Done Right Promise, which means a free return visit if the leak reappears within a year.
Chimney and Skylight Flashing
Most roof leaks in Houston trace back to failed flashing around chimneys, skylights, and vent pipes. We remove the old sealant and flashing, inspect the surrounding decking for hidden rot, and install new flashing with proper overlap and fasteners.
Leaks here are rarely fixed with a tube of caulk. The flashing has to be integrated with the shingles in the right order, or water will find a path within one season.
Decking and Underlayment Repair
When water has been getting in for months, the plywood decking under the shingles is often the first casualty. We cut out the rotted section, replace it with new decking, and lay down fresh underlayment before reinstalling shingles.
In Houston’s humidity, soft decking is a structural issue, not a cosmetic one. A repair that ignores rotted decking is a repair that fails at the first heavy rain.
Styles & brands we work with
Emergency Roof Repair
Emergency Roof Repair in Houston typically costs $400 to $1,200 for same-day response, tarping, and temporary or permanent fixes depending on the extent of the storm damage. When a tree limb punctures your roof or wind peels back a section of shingles, water is getting in right now, not in a week. Our phones are answered by a live person around the clock, and we dispatch a background-checked technician in a marked Brennan Roofing vehicle to secure your home with a tarp or make the repair the same day whenever conditions allow.
Storm Tarping and Board-Up
After a storm, the first job is stopping the water. We install a heavy-duty tarp over the damaged section, nail it down properly along the edges, and document the condition so the insurance adjuster can see exactly what happened.
A badly installed tarp becomes a sail in wind and rips off within hours. We use the right fasteners and pattern for Houston’s wind loads.
Overnight Stabilization
Some roof failures happen at 2 a.m., and nobody should sit under a leaking ceiling until morning. We stabilize the opening, contain any active water intrusion, and schedule the permanent repair with a written price before any work proceeds.
You’ll know the number before we start. That part of the Garrison Standard doesn’t change just because it’s an emergency.
Flat Roof Repair
Flat Roof Repair in Houston generally runs between $450 and $1,400 depending on whether the problem is a punctured membrane, failing seam, or ponding water that has saturated the insulation beneath. Flat roofs are common on mid-century homes in neighborhoods like Meyerland, Timbergrove, and sections of Spring Branch, and they fail differently than shingle roofs: water sits instead of running off, and every seam is a potential entry point. We inspect the entire flat surface, not just the visible damage, because membrane roofs often fail in one spot while water travels underneath to another.
Membrane and Seam Repair
Modified bitumen, TPO, and EPDM flat roofs all rely on seams and overlaps to stay watertight. We clean the damaged area, open the seam correctly, and re-weld or re-adhere the membrane using the manufacturer’s specified method.
Patching a seam with the wrong adhesive is a temporary fix that fails in Houston’s summer heat. We match the repair to the membrane type, not whatever is on the truck.
Ponding Water Solutions
Standing water on a flat roof in Houston is a slow death sentence for the membrane. We evaluate the roof slope, drains, and scuppers, and repair the underlying cause whether that’s a clogged drain, a sagging deck section, or an undersized scupper.
This isn’t alligatoring or cosmetic cracking. Ponding water that sits for 48 hours after a rain is actively shortening the life of the roof.
Shingle Roof Repair
Shingle Roof Repair in Houston usually costs $275 to $650 for a small cluster of damaged shingles, and $500 to $1,100 when the repair includes ridge caps, hip shingles, or a section of flashing. Asphalt shingles take a beating in this climate: UV exposure breaks down the granule coating, wind lifts the tabs, and hail leaves bruising that turns into leaks months later. We carry asphalt, architectural, and impact-resistant shingle options from GAF, CertainTeed, and Owens Corning so the replacement shingles match the existing roof as closely as possible in color and profile.
Hail and Wind Tear-Off
Houston gets its share of hail, and the damage often doesn’t show up as a visible hole. We inspect for granule loss, bruising, and broken tabs, and replace only the shingles that are actually compromised, not the entire roof unless the damage warrants it.
You’ll see the damaged shingles yourself before we replace them. We’ll explain what we’re seeing in plain English.
Ridge and Hip Cap Replacement
Ridge and hip caps take the most direct wind load on any shingle roof, and they’re often the first shingles to fail. We replace damaged caps with new shingles cut and installed for those specific angles, not just nailed over the old ones.
When caps fail, water enters along the entire ridge line. This is not a cosmetic issue; it’s the roof’s spine.
Storm Damage Roof Repair
Storm Damage Roof Repair in Houston ranges from $400 for a small wind-damaged section to $2,500 or more for extensive hail damage across multiple roof planes, with the exact number depending on the material and the square footage affected. Houston storms come in three flavors: spring supercells with hail, summer afternoon squalls with straight-line winds, and the occasional tropical system that tests every flashing joint on the house. We document everything with photographs, provide a written repair scope and price, and work directly with your insurance adjuster if you’re filing a claim.
Insurance Claim Documentation
Filing an insurance claim without proper documentation is how homeowners get lowballed. We photograph every damaged section, mark the roof with the same reference system adjusters use, and meet with the adjuster on-site to point out what we found.
You don’t have to be a roofing expert to file a claim. You just need a roofer who will stand next to you while the adjuster walks the roof.
Preventative Post-Storm Inspection
Not every storm requires a repair, but every major storm in Houston should trigger an inspection. We check for lifted shingles, broken seals, dented flashing, and granule loss that can’t be seen from the ground.
A $0 estimate and a clean bill of health beats discovering damage next spring when the leak has already ruined a section of decking.
Metal Roof Repair
Metal Roof Repair in Houston generally runs $450 to $1,600 for issues like loose or missing fasteners, failed sealant joints, or damaged panels that need replacement. Metal roofs are increasingly common in neighborhoods like Katy, Cypress, and Friendswood, and they last decades, but they still fail at the seams, the fasteners, and the flashings where one material meets another. We service standing seam, R-panel, and corrugated metal roofs, and we replace fasteners with the correct type for the panel profile and Houston’s expansion-and-contraction cycle.
Fastener and Sealant Failure
Metal panels expand and contract daily in Houston’s temperature swings, and over time that movement works fasteners loose and breaks down sealant. We replace loose fasteners with new ones that have intact washers, and re-seal panel overlaps with the proper metal roof sealant.
Loose fasteners on a metal roof are like a loose lug nut on a wheel: they don’t fix themselves, and they get worse every mile.
Panel Replacement
When a panel is dented, punctured, or corroded through, the right fix is replacing the panel, not smearing sealant over the hole. We match the panel profile and gauge, remove the damaged section, and install the replacement with new fasteners and sealant.
Mismatched panels leak at the overlap, and metal roof panels from different manufacturers don’t always interlock. We know which profiles work together.
Commercial Roof Repair
Commercial Roof Repair in Houston for small to mid-size commercial buildings typically costs between $800 and $3,500 depending on the roof system, damage extent, and whether the repair is isolated or sectional. Houston commercial roofs skew toward TPO, EPDM, and modified bitumen systems on low-slope structures, and they fail most often at penetrations: HVAC curbs, exhaust vents, gas lines, and rooftop equipment supports. Brennan Roofing Co Houston performs commercial roof repair for small offices, retail storefronts, and warehouse spaces with the same Garrison Standard applied to every job: written pricing, clean execution, and follow-up that’s guaranteed in writing.
Penetration and Curb Flashing
Most commercial roof leaks in Houston start where something pokes through the membrane. We strip back the old flashing, inspect the penetration for corrosion or rust, and re-flash with the correct materials for the specific roof system.
Every rooftop unit is an entry point. The roof itself may be in fine shape while the flashing around the AC curb is the entire problem.
Seam and Membrane Repair
TPO and EPDM seams are heat-welded or adhered, and when they fail, water gets between the membrane and the insulation. We perform a thorough moisture scan of the affected area, cut out saturated insulation where necessary, and re-weld the seam using the manufacturer’s specifications.
A wet seam is the start of a much bigger problem. Catching it before it spreads is the difference between a $1,200 repair and a $15,000 replacement.
Brands We Service
Brennan Roofing Co Houston installs and repairs shingle systems from GAF, CertainTeed, and Owens Corning, and the technicians know the install specifications for each. That matters because a GAF shingle and an Owens Corning shingle don’t always lay the same way at the ridge or the valley, and using the wrong nailing pattern voids the manufacturer warranty.
We also service and install Boral tile and metal roof systems where the fastening details, underlayment requirements, and flashing details differ significantly from asphalt shingle construction. Whether you have GAF, CertainTeed, Owens Corning, Boral, or any other make on your roof, we can repair it and back the work with the 365-Day Done Right Promise.

- Water stains on your ceiling after a rain. The water is already past the roof deck and into your home’s interior. Every rain event spreads the stain further and saturates more insulation and drywall.
- Lifted, cracked, or missing shingles visible from the ground. Each missing shingle exposes the underlayment and decking to direct water contact. In Houston’s climate, that exposure starts causing rot within weeks, not months.
- Granules collecting in your gutters. Asphalt shingles shed granules as they age and break down under UV exposure. Heavy granule loss means the shingles have lost their weather protection even if they look intact from the ground.
- Daylight visible in your attic. If you can see light through the roof deck from inside the attic, water can get through the same openings. This is one of the clearest early warning signs and costs nothing to check.
- Rust on metal flashing or exposed fasteners. Corroded flashing and fasteners are failing in slow motion. They may not leak today, but they will leak, and the damage hidden behind them gets more expensive the longer it sits.

How Much Does Roof Repair Cost in Houston?
Roof repair in Houston typically costs $275 to $1,500 for common residential repairs. Minor shingle replacements run $275 to $450, leak repairs with flashing work run $350 to $900, and sectional replacements involving decking, underlayment, and shingles run $800 to $1,500. Flat roof membrane repairs generally run $450 to $1,400, while emergency storm response with tarping starts around $400. Commercial roof repair on small to mid-size buildings ranges from $800 to $3,500.
The biggest factors affecting the price are the roof’s slope and height, the extent of hidden decking damage, and the material match required. A second-story steep-pitch roof costs more to work on than a single-story walkable roof, and a repair that requires matching discontinued shingle colors adds a premium. The way to avoid overpaying is to get the written price before work starts and to ask exactly what’s included. Our free estimate includes a full roof inspection, photographs of every issue, and a line-item written quote. When you call (940) 461-8481, you’ll get a live person and a scheduled appointment, no obligation.

Frequently Asked Questions About Roof Repair in Houston
Roof repair is the process of fixing a specific problem on an existing roof, such as a leak, damaged shingles, failed flashing, or a punctured membrane, without replacing the entire roof.

Repairs are usually done the same day once materials are matched and the scope is confirmed. Every repair we perform in Houston comes with a written price before work starts and a 365-Day Done Right Promise in writing.
Most residential roof repairs in Houston take between two and six hours depending on the extent of the damage and the accessibility of the roof section.
