Why Brennan Roofing Co Dallas Is Dallas’s Preferred Roof Repair Company
Brennan Roofing Co Dallas operates under The Garrison Standard, a defined code of conduct: written price before any work starts, background-checked uniformed technicians who show up inside the promised window, and a full-year written guarantee on every repair. Homeowners across Dallas tell us the same thing: they’ve been burned by roofers who no-show, bump the price at the door, or leave nails in the driveway. Those are exactly the failures The Garrison Code is built to eliminate.
Dallas homeowners also get a live person on the phone, 24/7. No voicemail, no automated system, no callback queue. When a storm rolls through at 2 a.m. and you’ve got water coming through the ceiling, someone real answers and starts scheduling. That matters in a city where severe thunderstorms can hit with almost no warning during spring and early summer.
Every technician we dispatch to a Dallas address is background-checked, uniformed, and trained to document what they find with photos before and after. You’ll know exactly who is on your roof and exactly what was done. Travis Oakley, who leads Brennan Roofing Co Dallas, holds every job to The Garrison Standard personally.
Styles & brands we work with






Emergency Roof Repair in Dallas
Emergency Roof Repair in Dallas is a specific job: a storm blows through, a limb punctures the decking, a section of shingles gets peeled back, and water is already finding its way inside. We tarp and temporarily seal the damaged area to stop active leaking, then return with a permanent repair once the weather clears and materials arrive. Tarping and temporary sealing in Dallas typically runs $300 – $500, and the permanent repair that follows depends on the damage: shingle replacement from $350, decking replacement from $200 per sheet, and flashing repair from $250.
Hail Damage Triage
Dallas sits in Hail Alley, and spring storms can dump golf-ball-sized hail on one block while the next street over gets nothing. When hail cracks shingles or knocks granules loose in a concentrated area, we document every impact point with photos and measurements. That documentation matters when you file a claim, and it’s part of the written record that comes with every Brennan Roofing Co Dallas job.
Temporary Weatherproofing
A leaking roof in Dallas doesn’t wait for a convenient time. We install heavy-duty tarping with battens secured to the deck, not just weighted down, so it holds through Dallas wind gusts. The goal is simple: keep water out tonight, then repair it right tomorrow or the next day.
Flat Roof Repair in Dallas
Flat Roof Repair in Dallas focuses on low-slope sections common on mid-century ranch homes, porch roofs, carports, and additions throughout the metro. Intense thunderstorms here drive water sideways and uphill under seams, so leaks on flat roofs often show up far from where the actual failure is. A typical flat roof patch in Dallas runs $450 – $800 for a small area, while larger resurfacing or seam work can reach $1,200 or more depending on square footage and membrane type.
Seam and Flashing Work
On flat and low-slope roofs, seams and flashing are the first things to fail after Dallas hail flexes the metal or the membrane. We don’t just smear sealant over a visible crack. We cut back the damaged section, inspect the substrate, and install new material that bonds cleanly. A patch done without opening the seam dry is a temporary fix at best.
Ponding Water Solutions
Dallas flat roofs often pond water at the low point near the scupper or drain because the original framing settled. Standing water accelerates membrane breakdown and eventually leaks. When we repair a flat roof in Dallas, we check drainage first. Sometimes the fix is a minor taper or a new drain basket, not another layer of coating.
Trusted Brands We Service in Dallas
We install and repair roofs built with materials from GAF, CertainTeed, Owens Corning, and other leading manufacturer lines, and we keep common Dallas parts in local stock so turnaround stays tight. That includes Atlas and Tamko shingles for hail-rated replacements, plus flashings, vent boots, and underlayment for storm repairs. When a Dallas homeowner needs a specific shingle matched after hail, we can usually source it from our Dallas-Fort Worth office supply chain without waiting on a special order from out of state.
Common Roof Repair Problems We See in Dallas Homes
- Hail-cracked shingles and granule loss. Dallas hail routinely strips the protective granules off composition shingles, exposing the asphalt mat underneath. Once the mat is exposed, UV heat above 100°F degrades it fast, and leaks follow within a season or two.
- Lifted and cracked flashing. Metal flashing around chimneys, vents, and valleys gets flexed by repeated hail impacts. Micro-cracks are invisible from the ground but leak during the next heavy thunderstorm.
- Failed vent boots on original 1970s – 2000s tract homes. The rubber gaskets around plumbing vents dry out and crack in Dallas heat. We see this on homes across Mesquite, Garland, and east Dallas, not just older neighborhoods.
- Wind-lifted shingles at eaves and rakes. Dallas storm winds grab the starter strip first. When the starter is stapled or under-nailed, sections of shingle peel back and expose the decking to rain.

The Wind Rating Your Dallas Repair Has to Meet
Here’s what most Dallas homeowners don’t hear until it’s too late: the building code requires asphalt shingles to meet ASTM D3161 Class F wind rating, which is 110 mph, for most residential roofs. But after the 2019 tornado outbreak, many Dallas insurers tightened their standards. They now demand ASTM D7158 Class H, rated at 150 mph or better, on new and repaired sections. That means a compliant quote has to specify the rated shingle and the nail pattern, not just the product name. A cheap bid that says “architectural shingles, installed” without naming the wind class won’t satisfy your insurer after the next hail claim, and it may not pass city inspection either.
A real example from our own work: on a 2003 tract home in Lake Highlands, our tech found original 3-tab shingles with granule loss from hail impacts and lifted starter strip at the eaves. We replaced the missing decking, installed GAF Timberline HDZ architectural shingles with a 130 mph wind rating, and added new drip edge and ice and water shield at the valleys before the insurance adjuster arrived to document compliance. That’s the difference between a repair that satisfies your policy and one that creates a fight with your carrier later.
What a Compliant Quote Includes That a Cheap One Leaves Out
- The wind class in writing. A compliant quote names the shingle (GAF Timberline HDZ, CertainTeed Landmark, Owens Corning Duration, Atlas StormMaster) and its ASTM D7158 Class H rating. A cheap bid just says “shingles.”
- A specified nail pattern. Class H-rated shingles require 6 nails per shingle, not the 4 nails common on builder-grade work. The nail pattern is part of the written quote.
- New drip edge and starter strip. Hail flexes metal, and reusing old drip edge means micro-cracks that leak within one storm cycle. The cheap bid reuses whatever is already up there.
- Ice and water shield in valleys and around penetrations. Dallas thunderstorms drive water uphill on low-slope ranch roofs. Skipping this membrane is the most common cause of repeat leaks we see.
- Post-repair documentation. Photos, measurements, and a written description of what was installed and to what standard. Your insurer needs that record after the next hail storm.

FAQs About Roof Repair in Dallas
A Dallas residential roof repair must meet at minimum ASTM D3161 Class F (110 mph), but most insurers now require ASTM D7158 Class H (150 mph) or better on repaired sections after the 2019 tornado outbreak. Ask for the rating in writing before you sign any repair contract. Call (903) 499-4441 and we’ll put the exact wind class and nail pattern on your written quote.
Yes. When your repair is documented with the wind class, nail pattern, and materials used, your insurer has a record showing the roof met their standards before the new damage occurred. That reduces disputes over whether pre-existing issues caused the leak. Brennan Roofing Co Dallas gives you that documentation with every job, in writing. Call (903) 499-4441 to schedule your free estimate and get the paperwork trail started.
Lake Highlands is an older suburb with original roofs from the 1970s and 1980s, and a single hail storm can strip enough granules and crack enough shingles that entire blocks fail at once. Roofers track the storm path door-to-door because insurance claims are tightly clustered. But not every crew that knocks is worth opening the door for. Get a written price with the wind rating in it before you sign anything. Call (903) 499-4441 for a quote that specifies what you’re actually getting.
In Dallas, intense thunderstorms drive water sideways and uphill, so a flat roof that only leaks during heavy rain usually has a seam or flashing failure that normal drizzle never exposes. The fix is opening the seam, replacing the damaged membrane, and checking drainage for ponding. Just sealing the visible crack won’t stop a Dallas thunderstorm leak. Call (903) 499-4441 and we’ll find the actual entry point, not just the wet spot on your ceiling.
A compliant quote specifically names the shingle and its ASTM D7158 Class H wind rating, the 6-nail pattern, new drip edge and starter strip, ice and water shield at valleys and penetrations, and post-repair documentation. A cheap bid says “shingle repair” and reuses whatever is already on the roof, including old flashing that hail has already micro-cracked. Call (903) 499-4441 for a written quote that won’t fail your next insurance claim.
