AfterTrusted Roof Repair Nationwide
Roof repair stops a small problem from becoming a structural one. A missing shingle, a cracked boot, or a section of flashing that has pulled away from a chimney lets water into places it should never reach. Brennan Roofing fixes these issues under The Garrison Standard: a written price before any work starts, a background-checked uniformed technician on site, and a full-year written guarantee on the repair. Our crews serve homeowners and businesses across the United States, including our Roof Repair in Los Angeles. If you need roof repair, call (361) 320-9467 and speak with a live person, any hour, any day.
Roof Leak Repair
Roof Leak Repair is the process of finding where water enters a roof system and sealing it before it damages decking, insulation, ceilings, or framing. Most leaks are not where the stain appears on the ceiling. Water travels along rafters and sheathing, sometimes for several feet, before it drips onto drywall. That means a leak repair job starts with a real investigation, not a bucket of tar on the first suspect spot.
Finding the True Entry Point
We trace water intrusion back to its source. Our technicians check flashing, pipe boots, valleys, skylights, and attic decking for the telltale watermark that points upstream. Fixing the visible stain without sealing the actual entry point just means the stain comes back after the next hard rain.
What Roof Leak Repair Costs
Roof Repair pricing through Brennan Roofing for leaks typically runs $200 to $700 depending on how far the water has traveled and how many materials need replacement. Flashing repairs and pipe boot replacements sit at the lower end. A leak that has rotted a section of decking runs higher because the bad wood must be cut out and replaced before any new underlayment goes down.
Emergency Roof Repair
Emergency Roof Repair is the stop-the-bleeding work that happens right after a tree limb drops, a storm rips shingles off, or a skylight cracks under hail. The goal is fast protection: keep water out tonight, then do the permanent fix when the weather clears. Brennan Roofing answers the phone with a live person 24 hours a day, so an emergency call never goes to voicemail.
Temporary Protection That Holds
We secure tarps, seal the exposed decking, and fasten loose membrane so the structure stays dry until a full repair can be scheduled. Every tarp is anchored to the roof structure itself, not just weighted down with bricks. Wind is the enemy of a bad tarp job, and ours stay put.
What Emergency Roof Repair Costs
Emergency roof repair typically costs $350 to $900. The range depends on how much surface area needs covering, how difficult the access is, and whether the damage is a single missing shingle or a full slope of torn roofing. The written price is placed in your hand before any temporary work begins.
Flat Roof Repair
Flat Roof Repair addresses the unique issues of low-slope and flat roof systems: ponding water, split seams, blistered membrane, and failed patches around penetrations. Flat roofs are not actually flat. They carry a slight slope toward drains and scuppers, but when that drainage slows or clogs, standing water eats away at the membrane and shortens the roof’s life by years.
Membrane and Seam Repairs
We repair built-up roofing, modified bitumen, EPDM, TPO, and PVC systems. Each material has its own weld or adhesive requirements, and using the wrong one is how a flat roof repair fails within months. Our technicians match the repair method to the existing membrane, never the other way around.
What Flat Roof Repair Costs
Flat roof repair through Brennan Roofing typically runs $300 to $900 depending on the size of the affected area and the membrane type. A small seam split is often a quick heat-weld or patch. A section of waterlogged insulation below the membrane changes the scope completely, because the wet material must be removed and replaced.
Shingle Roof Repair
Shingle Roof Repair covers replacing cracked, curled, missing, or wind-damaged asphalt shingles before the decking underneath is exposed. A single missing shingle can become a roof replacement if it is ignored through one wet season. Shingle repair is the most common roof repair we do, and it is usually the most straightforward when caught early.
The Right Shingle, Matched
Color and profile matching matters. A mismatched patch looks like a scar and does not seat the same way against its neighbors. We repair shingle roofs with products from manufacturer lines including Owens Corning, GAF, and CertainTeed, matched to the existing roof so the repair blends and seals correctly.
What Shingle Roof Repair Costs
Shingle roof repair typically runs $180 to $500 for a small section, depending on the pitch of the roof and how many layers are on the roof deck. Steep roofs and tall two-story houses cost more because of ladder and safety setup. The written price you get before we start is the price you pay when we are done.
Storm Damage Roof Repair
Storm Damage Roof Repair is the repair work that follows wind, hail, or falling debris. Wind tears shingles at the nail line. Hail bruises the mat and loosens granules. A tree branch punches through the decking. None of these should wait for a convenient season, because the exposed roof is taking on water with every rain. For guidance on what to expect, see The Complete Roof Repair Guide for Los Angeles Homeowners.
Working With Your Insurance Claim
We document storm damage with photos and a written scope of repair so you have a clear record for your insurer. We do not negotiate your claim for you, but we give you honest repair numbers that match what we would charge any homeowner for the same work. No inflated “insurance pricing” and no lowball estimate that dies at the adjustment.
What Storm Damage Roof Repair Costs
Storm damage roof repair through Brennan Roofing typically runs $300 to $1,000 depending on the scale of the damage. A few lifted shingles are on the low end. A tree-branch puncture that requires decking replacement and new underlayment runs higher. The estimate includes every line item in writing before work starts.
Metal Roof Repair
Metal Roof Repair handles the distinctive failure points of standing seam, corrugated, and metal shingle roofs: loose fasteners, failed sealant at panel laps, rust around the screw heads, and open seams at ridges and transitions. Metal roofs are not maintenance-free. They are long-wearing when details hold, and the details are where they fail.
A Permanent Fix, Not a Caulk Gun
We replace failed fasteners with the correct gasket screws, re-secure loose panels, and strip and reseal open seams with a metal-rated sealant. Caulk is not a roof repair. It is a temporary bridge that fails again when the panels expand and contract through the seasons.
What Metal Roof Repair Costs
Metal roof repair typically costs $250 to $800 depending on the number of seams and fasteners involved. A single loose panel on a low pitch is a quick job. A ridge cap that has lifted for twenty feet requires more fastener and sealant work, and the price reflects the linear footage.
Commercial Roof Repair
Commercial Roof Repair covers the low-slope membrane systems on warehouses, offices, strip centers, and apartment buildings. The priorities are different than residential work: protecting inventory, keeping tenants dry, and staying out of the way of daily operations. We dispatch uniformed technicians who work around your schedule, not against it.
Low-Slope Systems We Know
We repair TPO, PVC, EPDM, modified bitumen, and built-up roofing on commercial properties. Each requires its own welding or patch method. We inspect the field of the roof, the flashings, and the penetrations before any patch goes down, then put the price in writing so the building owner knows exactly what the scope is.
What Commercial Roof Repair Costs
Commercial roof repair typically starts around $500 and runs to $1,500 for larger or multi-point repairs depending on square footage and membrane type. Roof access, safety railings, and after-hours work also shape the written estimate. Every quote is line-itemed so the owner sees material and labor separately.
Brands We Service
We repair and install roofing from the manufacturer lines homeowners and building owners actually ask for: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That is not a list we rattle off. It means our crews know the fastener patterns, warranty registration, and installation tolerances for each line, so we repair what is already on the roof instead of pushing a rebuild.
CertainTeed and Owens Corning shingle systems are among the most common we service, and we keep their repair standards in front of us on every asphalt roof job. IKO and Atlas products show up regularly on storm-repair work, where matching the existing shingle is half the job. Whether you have one of those brands or any other make, we can help.
Signs You Need a Pro Right Now
- Water stains on the ceiling or upper walls. The leak has already passed through the roof deck and insulation. Waiting weeks to find the source just spreads the damage into drywall and framing.
- Shingles in the yard after a storm. Shingles do not come off one at a time. If you see them on the ground, the field of the roof has already lost its water barrier in those areas.
- Daylight through the attic boards. If you can see sky from the attic, the roof deck has a penetration point. That opening is taking water every time it rains, even if you have not seen a stain yet.
- Granules collecting in the gutters. Asphalt shingles shed granules as they age, but a sudden heavy buildup means the mat is exposed and the shingle is losing its weather resistance fast.
- Flashing that is lifted away from the wall or chimney. Flashing holds back the water at every transition. Once it pulls away, caulk will not hold it. The metal needs to be re-secured and sealed by a technician who knows how to do it right.
Our Process, Step by Step
- 1
You call, you talk to a person. No phone tree, no voicemail, no call center script. You describe the problem to a live person who schedules a technician to look at it.
- 2
We inspect and diagnose. The technician walks the roof and attic to find the real failure point, not just the visible symptom. That means tracing water marks, checking decking condition, and verifying that adjacent seams and flashings are still sound.
- 3
You get a written price. The scope of repair, the materials, and the labor are all on paper before any work begins. That price does not change at the door, and there are no surprise change orders. Follow-ups on extras are priced in writing first too.
- 4
The repair is done to The Garrison Standard. A uniformed, background-checked technician completes the work, cleans the job site, and walks you through what was fixed and why. You see the repair and understand it.
- 5
You get the 365-Day Done Right Promise. Every repair is guaranteed in writing for one full year. If it fails within that year, we return and make it right at no charge. That is not a hope. It is in writing.
How Much Does Roof Repair Cost?
A typical shingle repair runs $180 to $500 depending on the roof pitch and the number of shingles replaced. A roof leak repair usually lands between $200 and $700 depending on whether the leak is a simple flashing fix or has damaged the decking. Flat roof repair runs $300 to $900 by membrane type and wet insulation. Emergency roof repair, because of the speed and staging involved, typically costs $350 to $900. Storm damage repair starts at $300 and can reach $1,000 when the decking or underlayment is compromised. Metal roof repair runs $250 to $800 depending on how many seams and fasteners need replacement. Commercial roof repair generally starts at $500 and can run to $1,500 for larger multi-point scopes.
What changes the price most is what is beneath the surface: rotted decking, wet insulation, or a hidden leak path that has traveled through the roof assembly. That is why our free estimate starts with a real inspection, and why the written price includes line items for everything we find. You avoid overpaying by knowing exactly what is being fixed and why before any work starts. The free estimate gives you that without any obligation.

Wherever the roof is, the discipline is the same: a written price before work starts, a background-checked uniformed technician on site, and a full-year written guarantee when the repair is complete.
Frequently Asked Questions About Roof Repair
Roof repair is the targeted correction of a specific failure on an existing roof: a leak, a missing shingle, failed flashing, a split seam, or storm damage. It focuses on restoring the affected area instead of replacing the whole roof system. A proper repair extends the roof’s life and keeps water out of places it should never be.
Most single-issue roof repairs are completed in one day, often in a few hours. Larger scopes with decking replacement or multiple leak points can take two visits. The written estimate includes the expected timeline so you know before work starts.
Most residential roof repairs run between $180 and $1,000, with the final number set by what is actually wrong. The only way to know precisely is a real inspection. We give you that number in writing before any work starts, and it does not move. Call (361) 320-9467 for a no-obligation estimate.
Yes. We repair and install roofing from manufacturer lines including Owens Corning, CertainTeed, GAF, IKO, Atlas, Tamko, and Boral. Matching the repair to the existing shingle system is standard practice on every asphalt roof we touch.
Yes. Brennan Roofing answers the phone with a live person 24 hours a day, and we dispatch for storm and leak emergencies outside normal business hours. No voicemail, no callback queue. A person picks up.
