Trusted Roof Repair for Fresno Homeowners
Roof repair in Fresno typically runs between $350 and $1,500 for most residential fixes, with leak repairs starting around $350 and full roof replacements climbing higher. We’re Brennan Roofing Co Fresno, and we’ve been holding our work to a written standard since 2000 through the Garrison Partners family. Travis Oakley leads our crew, and every technician who steps onto your roof is background-checked, uniformed, and answers to the same rule: the price goes on paper before any work starts. If you’re dealing with a leak, missing shingles, or storm damage right now, call (559) 785-2160 and a live person picks up. No voicemail, no callback queue.
Roof Leak Repair
Leak Repair means finding where water gets in and stopping it before it rots the decking, soaks the insulation, or stains the ceiling. In Fresno, leaks rarely announce themselves loudly. They start as a faint water mark, a musty smell in the hallway, or a drip that only shows up after a hard rain. By the time you see it inside, water has usually been traveling through the roof assembly for weeks. That’s why we trace the leak to its source, not just its symptom. A stain on the living room ceiling might come from a cracked pipe boot near the ridge vent twenty feet away. We fix the source, replace the damaged underlayment, and document everything in writing. Most leak repairs in Fresno run $350 to $900 depending on access, roof pitch, and how far the water traveled.
Ceiling Stains and Hidden Water
A brown ring on the ceiling means water has already saturated the drywall. The roof penetration could be a nail hole, a failed shingle seal, or a gap in the flashing. We inspect the attic side first because the water trail tells us exactly where the breach happened, then we repair the roof deck if the wood has softened. Northern Fresno homes built in the 1980s and 1990s often show this failure around plumbing vents where the rubber boot has cracked under the valley sun.
Flashing and Pipe Boot Failures
Flashing Repair involves replacing the metal or rubber material that seals the joints where the roof meets a chimney, wall, skylight, or vent pipe. Pipe boots, specifically, dry out and split in Fresno’s summer heat after eight to twelve years. We replace failed flashing with new material, re-seal the seam, and confirm the repair with a water test before we leave. Call (559) 785-2160 if you suspect a flashing failure; the fix is usually same-day and less than $600.

Emergency Roof Repair
Emergency Roof Repair means stopping active water from entering your home right now, not scheduling an inspection for later in the week. In Fresno, emergencies usually follow the winter storm systems that roll through between November and March, or a tree branch that comes down in the wind. If water is coming in, your first move is to contain what you can inside, then call (559) 785-2160. A live person answers around the clock, and we’ll dispatch a background-checked technician to tarp the damaged area or make a temporary patch that holds until permanent repairs can be scheduled. Emergency roof repair in Fresno typically runs $500 to $1,500 depending on severity, roof access, and the extent of temporary protection needed.
Storm Tarping and Temporary Protection
When a tree limb punctures the roof deck or wind peels back a section of shingles, the immediate priority is keeping more water out. We install heavy-duty tarps anchored to the roof structure, not just weighted down with bricks. The tarp is a bridge, not a fix. It buys you dry days while we put together a written quote for the permanent repair, and that quote still follows the same rule: price on paper before any work starts.
After-Hours Response in Fresno
Roof failures don’t wait for business hours, and neither does our phone. You’ll reach a real person at 3 a.m. the same way you will at noon. We serve Fresno and the surrounding cities including Clovis, Sanger, Kerman, and Fowler, and we’ll give you an honest assessment over the phone before a technician ever arrives. If it can wait until morning, we’ll tell you that too.
Flat Roof Repair
Flat Roof Patch work addresses the specific failure patterns of low-slope and no-slope roofing systems, which are common on mid-century Fresno homes, additions, carports, and commercial buildings. Unlike shingle roofs that shed water by gravity, flat roofs rely on a continuous waterproof membrane to hold water back. When that membrane cracks, blisters, or separates at a seam, water pools and eventually finds its way through. Common flat roof systems in Fresno include built-up roofing, modified bitumen, and single-ply membranes like TPO. We repair punctures, re-seal seams, replace damaged membrane sections, and fix the drainage issues that cause standing water in the first place. Flat roof repairs in Fresno typically run $400 to $1,200 depending on membrane type and damage extent. If your roof is over ten years old, call (559) 785-2160 for an inspection; the cost of waiting is usually a full replacement, not a patch.
Ponding Water and Drainage Issues
Standing water that lingers more than 48 hours after rain shortens the life of any flat roof membrane. It accelerates UV breakdown, invites algae growth, and finds every micro-fracture. We correct ponding by adding tapered insulation, cleaning and re-setting drains, or adding crickets to direct water toward the scupper. In Fresno’s older neighborhoods like the Tower District and Sunnyside, we regularly see flat roofs where the original drain design simply wasn’t enough for the roof’s surface area.
Membrane Repair and Seam Sealing
A torn or punctured membrane is not a DIY patch job. Incorrect materials or an improperly prepped seam will fail within months, and then you’re paying twice. We match the membrane type already on the roof, clean and prime the area properly, and apply the patch or seam seal with the manufacturer’s specified method. Every repair carries the 365-Day Done Right Promise: if it fails within a full year, we come back and make it right at no charge.
Shingle Roof Repair
Shingle Replacement and broader shingle roof repair covers everything from replacing a handful of blown-off shingles to re-sealing entire slopes that have lost their weather barrier. Asphalt shingle roofs dominate Fresno residential construction, and they fail in predictable ways: granule loss, curling, cracking, and wind lift. The valley’s summer heat accelerates shingle aging, especially on south-facing and west-facing slopes where daytime surface temperatures routinely exceed 150 degrees. We repair shingle roofs by removing damaged shingles, checking the underlayment beneath, and installing new shingles from the same manufacturer line and the same color family so the repair blends. Shingle roof repairs in Fresno typically run $350 to $1,100. The repair is usually completed the same day we start, and the price is written down before a single shingle comes off.
Missing Shingles and Wind Lift
When Fresno gets a strong winter system, the leading edges of shingles catch the wind like little sails. Once a shingle lifts, water gets under it, and the seal strip never reseats properly. Left unrepaired, missing shingles expose the underlayment to direct sun and rain, which accelerates deterioration across the whole slope. We replace missing and lifted shingles, re-nail adjacent shingles that have loosened, and check for granule loss on surrounding courses. Most missing shingle repairs cost between $350 and $600.
Granule Loss and Sun Damage
Check your gutters after a rain. If they’re collecting a fine black grit, that’s your shingle surface washing away. Granules protect the asphalt base from UV radiation. Once they’re gone, the shingle dries out and cracks within a season or two. Homes in newer Fresno developments like Harlan Ranch and Fancher Creek have newer roofs, but older neighborhoods along Blackstone and First Street show significant sun damage on original shingles from the 1990s. Call (559) 785-2160 and we’ll tell you honestly whether the roof has repair life left in it or whether it’s time to plan a replacement.
Storm Damage Roof Repair
Storm Damage Roof Repair addresses roof failures caused by wind, hail, falling branches, and the intense rain events that sweep through Fresno County during the winter months. The Central Valley doesn’t get hurricanes, but it does get straight-line winds strong enough to peel shingles, and hailstorms that can bruise or crack shingle surfaces. After a storm, we inspect for lifted shingles, damaged flashing, punctured decking, and hail impacts. We document everything with photos, write the repair scope on paper, and give you a copy before any work begins. Storm damage repairs in Fresno typically run $500 to $2,000, depending on whether the roof needs isolated shingle replacement, new flashing, or decking repair. If a storm just rolled through, call (559) 785-2160 before the next one finds its way inside.
Wind and Hail Damage Assessment
Hail damage is not always obvious from the ground. The shingles may look fine while the mat underneath has been fractured by impact, which shortens the roof’s life significantly. We inspect the roof surface up close, check the ridge caps and flashings, and document every damaged area with photos you keep. If you’re filing an insurance claim, we’ll provide the documentation your adjuster needs to see the full scope. We won’t tell you to file a claim if the damage is less than your deductible; that’s a decision for you and your agent, but we’ll give you honest numbers either way.
Post-Storm Water Intrusion
Sometimes a storm doesn’t rip shingles off; it just pushes water sideways into places it never normally goes. Water seeps under the drip edge, behind the fascia, or through a flashing seam that’s been stressed by wind. If you noticed water inside during or after a recent storm, don’t wait to see if it happens again. The next rain will be worse because the pathway is already open. We’ll trace the intrusion, repair the roof assembly, and replace any damaged interior surface only if you ask us to; our scope is the roof, and we’ll be clear about what’s roofing versus drywall.
Metal Roof Repair
Metal Roof Repair covers standing seam panels, corrugated metal, and metal shingle systems, all of which are growing in Fresno as homeowners look for fire-resistant and long-life roofing options. Metal roofs last a long time, but they’re not maintenance-free. Screws back out, washers degrade, panels expand and contract with temperature swings, and seams can open up over time. We repair metal roofs by replacing failed fasteners, re-sealing seams, correcting panel overlap issues, and addressing rust at cut edges before it spreads. Metal roof repairs in Fresno typically run $400 to $1,300. The work requires specific tooling and experience with metal panel systems; a wrong fastener or an incompatible sealant can ruin a panel. Travis Oakley has kept our crew trained on standing seam and exposed-fastener systems so the repair looks like it belongs, not like a patch.
Loose Fasteners and Seam Leaks
On exposed-fastener metal roofs, every screw is a potential leak point. The neoprene washer under the screw head degrades in the Fresno sun and rain, then water follows the screw shank down into the roof assembly. We inspect fastener patterns, replace worn screws with properly matched fasteners, and re-torque loose ones to the panel manufacturer’s spec. On standing seam systems, leaks usually come from seam separation or failed sealant at the panel ends. We re-seal those seams with products rated for the panel coating, not a generic caulk from the hardware store.
Rust and Panel Replacement
Once rust starts at a panel cut edge or a scratch, it spreads under the paint film and eventually eats through the steel. We cut out the damaged section, replace it with matching panel material, and treat the surrounding area to slow further corrosion. The goal is to stop the rust, not just hide it. Most isolated panel replacements run $400 to $900, and we’ll tell you if the rust pattern suggests a larger problem with the original installation.
Commercial Roof Repair
Commercial Roof Repair serves Fresno businesses, property managers, and building owners with flat and low-slope roofing systems that protect inventory, equipment, and employees. Every day a commercial roof leaks, the cost stacks up: damaged stock, interrupted operations, safety hazards on wet floors, and liability. We repair TPO, PVC, modified bitumen, and built-up roofing systems on warehouses, retail spaces, office buildings, and multi-unit properties across Fresno, Clovis, and the surrounding industrial areas. Commercial roof repairs in Fresno typically run $800 to $3,500, depending on the membrane type, roof size, and how far the water has traveled into the insulation. We work around your operating hours when necessary, and we put the repair scope and price in writing before anything starts. Call (559) 785-2160 and ask for Travis Oakley to schedule a commercial inspection.
TPO and Single-Ply Repairs
Single-ply membranes like TPO fail most often at the seams, where heat-welded joints break down over time. A separated seam lets water through even when the rest of the membrane looks fine. We repair seams with hot-air welding equipment, not adhesives, because heat welding matches the original installation method and creates a bond as strong as the surrounding membrane. We also repair punctures from foot traffic, HVAC service, and debris, and we’ll flag areas where the roof design is inviting repeat damage.
Built-Up and Modified Bitumen Systems
Older commercial buildings in Fresno, especially along the Highway 99 corridor and downtown, still carry built-up roofs with gravel surfaces or modified bitumen caps. These systems fail differently: blisters form, gravel wears away, and the asphalt oxidizes until it cracks. We repair blisters by cutting out the damaged layers, drying the insulation beneath, and building the system back up in layers. We also do full resurfacing on modified bitumen roofs when the membrane has enough life left to justify it. You’ll get the written price before the first cut is made.
Brands We Service
We install and repair GAF, CertainTeed, and Tamko shingle systems, and we know their installation specs and warranty requirements well enough to keep your system in compliance. GAF’s Timberline line is the most common shingle we see on Fresno roofs, and we keep the color-matched bundles available for repairs so the patch doesn’t stand out against the existing roof. CertainTeed’s Landmark line shows up frequently on newer construction in the Clovis and northeast Fresno areas, and Tamko’s Heritage series is common on older homes that were re-roofed in the early 2000s.
We also service Boral tile and slate-look systems, which appear on many higher-end homes in Fresno’s Woodward Park and Fig Garden neighborhoods. Boral’s concrete tile roofs require a different repair approach than asphalt shingles; walking them wrong breaks tiles, and replacing a tile without the right underlayment detail creates a leak path. We know the difference. Whether you have GAF, CertainTeed, Tamko, Boral, or any other manufacturer’s roof, call (559) 785-2160 and we’ll give you an honest assessment.

- Water stains on the ceiling or walls. A stain means water has already saturated the drywall and is traveling. The longer it sits, the more it costs to fix. Ceiling stains rarely correspond directly to the roof breach location, so don’t try to guess; call us and we’ll trace the path.
- Missing or lifted shingles after wind. Once a shingle lifts, the seal is broken and it will never re-adhere. Every rain that follows pushes water under the surrounding shingles. Missing shingles on a bare slope are an open door for water, and the fix is usually under $600 if you catch it early.
- Granules collecting in the gutters. If your downspouts are depositing a black, sand-like grit, your shingles are shedding their protective coating. This means the roof is aging fast and losing its ability to block UV. It’s not an emergency, but it’s a signal to plan for repair or replacement before a leak develops.
- Daylight visible in the attic. Go into the attic on a sunny day and look up. If you see pinpoints of light through the roof deck, those are holes. Water will find them. If the deck is soft to the touch or shows dark water trails, the damage is already underway.
- Sagging or soft spots on a flat roof. A spongy area when you walk a flat roof means the insulation or decking underneath is saturated and losing structural strength. This is the stage before a full failure. Standing water that doesn’t drain after 48 hours accelerates the problem and needs correction.
Our Process, Step by Step
- 1
Call us and talk to a live person. You call (559) 785-2160 and reach a real human being, day or night. We’ll ask about what you’re seeing, when it started, and whether water is actively entering the home. Based on that conversation, we’ll tell you whether you need an emergency response or a scheduled inspection, and we’ll give you a window for arrival that we actually keep.
- 2
On-site inspection and documentation. A background-checked technician in a Brennan Roofing uniform arrives inside the promised window. We inspect the roof surface, attic, and interior damage thoroughly, taking photos as we go. You’ll see what we see. We trace the water path from entry point to exit point so the repair addresses the true source, not just the visible symptom.
- 3
Written price before any work starts. We write up the repair scope and put the price on paper. That number does not change at the door. No surprise change orders, no “while we’re up there” upsells. You approve the written price, and only then does work begin. This is the Garrison Standard, and there are no exceptions to it.
- 4
Repair and verification. We execute the repair with materials matched to your existing roof system and manufacturer specs. After the repair, we water-test flashings and seams where applicable and do a final inspection of the surrounding area to make sure we didn’t miss adjacent damage that will become next year’s leak.
- 5
Written guarantee and follow-up. Every repair carries the 365-Day Done Right Promise: a written guarantee for one full year. If the repair fails within that period, we come back and make it right at no charge. That’s not a verbal promise. It’s in writing, and it’s the Garrison Code.
How Much Does Roof Repair Cost in Fresno?
A typical roof repair in Fresno runs $350 to $1,500. A simple shingle replacement or small flashing repair lands on the lower end of that range, usually $350 to $600. A leak that requires tracing, decking repair, and underlayment replacement runs $600 to $1,200. Emergency tarping and temporary protection typically costs $500 to $800, and commercial repairs start around $800 and run up to $3,500 depending on the membrane type and damage extent. Metal roof repairs sit between $400 and $1,300. Storm damage repairs run $500 to $2,000 when multiple areas are affected.
What moves the price is access and extent. A steep roof on a two-story home costs more to work on than a single-story low-slope roof. Water that’s traveled through multiple layers of the roof assembly costs more to repair than surface damage you caught early. The age of the roof matters too; a 20-year-old shingle roof with widespread granule loss may not be worth repairing in pieces, and we’ll tell you that honestly. The free estimate we give you includes a written, itemized price. You’ll know what the repair costs before you decide whether to proceed, and nothing gets added at the door.

Frequently Asked Questions About Roof Repair in Fresno
Roof repair is the process of fixing a specific failure point on an existing roof: a leak, missing shingles, damaged flashing, a punctured membrane, or storm damage. Unlike a full roof replacement, which removes and replaces the entire roofing system, repair targets the damaged area and restores the roof’s waterproof integrity. In Fresno, most roof repairs address age-related shingle failure, sun-damaged flashing, or wind damage from winter storms. We repair all major roof types, including asphalt shingle, metal, tile, and flat membrane systems.
Most residential roof repairs in Fresno are completed in one day. Simple shingle replacements and small flashing repairs take two to four hours on site. A leak repair that involves decking replacement or multiple repair locations may take a full day. Emergency tarping can be done in under an hour once the technician arrives. Commercial repairs on large flat roofs may take two to three days depending on the scope. Call (559) 785-2160 and we’ll give you a realistic time estimate for your specific situation.
Roof repair in Fresno typically costs between $350 and $1,500 for residential work.

If the repair fails within that period for any reason, we come back and make it right at no charge. That guarantee is part of the Garrison Standard, and it’s not a verbal promise; it’s written into the work order you sign. We also honor manufacturer warranties on any materials we install, and we’ll explain what’s covered by that warranty versus ours before you approve the work.
You don’t need to do much, but a few things help: clear vehicles from the driveway or area directly under the roofline if possible, and move anything fragile away from interior walls near the leak. If you have pets, secure them so the technician can move through the house and attic without disturbance. We’ll handle everything on the roof itself, including moving gutters debris and laying protection over landscaping where needed. You’ll get a call or text when the technician is on the way, and the price is already in your hands before we start.
