Roofing Company in Dallas - Written Price, Workmanship Warranty

Trusted Roofing Company for Dallas Homeowners

If you own a home in Dallas, you already know the score. Hail season runs from March through June, summer heat pushes attic temperatures past 140 degrees, and spring storms can tear shingles off a roof in minutes. A roof that’s compromised doesn’t just leak. It invites rot, mold, and structural damage into the most expensive asset you own. Brennan Roofing Co Dallas operates 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. Call (903) 499-4441 and you’ll speak with a live person, not a voicemail tree.

• Materials from GAF, CertainTeed, and Owens Corning, explained plainly.

Roofing Contractor

A roofing contractor is the licensed professional who installs, repairs, and maintains the roof system over your head. You need one when shingles are missing, flashing is pulling away, a leak has stained your ceiling, or your roof is 18 to 20 years old and nearing the end of its service life. In Dallas, where hail and wind routinely strip roofs, a contractor’s job is to diagnose damage correctly and fix it before water finds a way in. Brennan Roofing Co Dallas provides roofing installation and replacement, repair, and inspection, with every job backed by The Garrison Standard.

Inspection Before Recommendation

We walk the entire roof surface, check valleys, flashing, and penetrations, and document what we find. You get a plain-English report with photos, not a sales pitch. No work begins until you’ve signed off on a written price.

Seasonal Storm Response

After a Dallas hailstorm, we start with the obvious damage and work inward. We’ve repaired roofs in Rowlett and Cedar Hill where quarter-size hail had fractured shingles in patterns visible only after the sun came up. If we find damage, we show you.

Commercial Roofing

Commercial roofing covers low-slope and flat roof systems on warehouses, offices, retail buildings, and multifamily properties across Dallas. These roofs take a different beating than residential pitches: ponding water after heavy rain, UV exposure that breaks down membrane seams, and foot traffic from HVAC maintenance. Brennan Roofing Co Dallas installs and repairs TPO, EPDM, and modified bitumen systems, and we always start with a written price before any work begins.

Flat Roof Realities

Flat roofs don’t drain like pitched roofs. In Dallas, a two-inch rain event in June can leave water standing for days if drains are clogged or the deck has settled. We inspect the membrane, seams, and flashing first, then address drainage before it becomes a leak.

Minimizing Business Disruption

We schedule work around your operation, whether that means nights, weekends, or phased sections. Our crews clean up the same day, every day. You’ll know exactly who’s on your roof because our technicians arrive in uniform and carry identification.

Metal Roof Installation

Metal roof installation means replacing your existing roof with standing seam panels or metal shingles. You need it when your current roof has reached the end of its life and you want a 40-to-60-year solution instead of another asphalt cycle. In Dallas, metal roofs reflect heat, reduce attic temperatures, and stand up to hail better than standard shingles. Brennan Roofing Co Dallas installs metal roofing systems and walks you through material options before you commit a dollar.

Standing Seam vs. Metal Shingles

Standing seam runs vertical panels from ridge to eave and hides all fasteners. Metal shingles look like traditional roofing from the curb. Both require proper underlayment, and we install both with the same discipline: a written price first, a uniformed crew on site, and a one-year guarantee in writing.

Hail and Heat Performance

Dallas hail can dent metal, but it rarely breaks through. We recommend heavier-gauge panels for homes in Haltom City and Lancaster where hail frequency is higher. Heat-wise, a reflective metal roof can cut afternoon attic temperatures by 20 to 30 degrees, which your air conditioner will notice.

Residential Roofing

Residential roofing is the installation, replacement, and repair of the roof system on any single-family home, townhome, or duplex. You need it when your roof leaks, when shingles blow off in a storm, when you’re buying or selling a home and the inspector flags the roof, or when your roof has simply aged out. In Dallas, an asphalt shingle roof typically lasts 15 to 20 years depending on ventilation, tree cover, and how much hail it’s absorbed. Brennan Roofing Co Dallas handles the daily roofing needs of Dallas homeowners from Uptown to Seagoville.

Steep and Complex Roofs

Two-story homes in University Park and older homes in Oak Cliff often have steep pitches, multiple valleys, and skylights. Those are exactly the places where leaks start. We inspect the valleys and flashing first, because that’s where poor workmanship shows up years before the shingles fail.

Full Replacement Process

We strip the old roof, inspect and replace the decking where it’s rotted, install new underlayment and drip edge, and lay the shingles per manufacturer spec. You get a written price before the first nail goes down, and that price does not move at the door.

Roof Maintenance

Roof maintenance is the scheduled inspection and minor repair work that keeps a roof performing before it fails. You need it twice a year in Dallas: once in spring after hail season starts, and once in fall before winter rains. For a complete guide, see our Roofing Company Maintenance Checklist for Dallas Homeowners. The goal is to catch cracked pipe boots, missing shingles, or clogged valleys while the fix costs a few hundred dollars instead of a few thousand. Brennan Roofing Co Dallas maintains residential and commercial roofs with the same written-price discipline we bring to full replacements.

What a Maintenance Visit Covers

We inspect shingles, flashing, valleys, pipe boots, vents, and the underside of the deck from the attic. We clear debris from valleys and gutters. If we find something small, we fix it on the spot if materials are on hand. If we find something big, you get a written quote before any additional work proceeds.

Documentation for Insurance

After every maintenance visit, we document your roof’s condition with photos and notes. When a storm hits Dallas, having a maintenance history on file helps you file an accurate insurance claim. We’ve helped homeowners in Mesquite and Hutchins who had years of records that proved pre-existing condition versus storm damage.

Roof Coating

Roof coating is a liquid-applied, seamless membrane that gets rolled or sprayed onto an existing flat or low-slope roof. You need it when your commercial roof is aging but structurally sound, and you want to extend its life without the cost and disruption of a full tear-off. In Dallas, coatings also reflect UV and lower the surface temperature, which reduces cooling load. Brennan Roofing Co Dallas applies silicone, acrylic, and elastomeric coatings, and every coating job gets a written price and the one-year done-right guarantee.

When Coating Makes Sense

Coatings work best on roofs with good drainage and no saturated insulation. We inspect the deck and check for moisture before recommending a coating. On a roof that’s already failing, coating is a band-aid, and we’ll tell you that plainly before you spend a dime.

Energy and Longevity

A white reflective coating in Dallas can drop roof surface temperature by 50 degrees on an August afternoon. That’s real money off the cooling bill. Applied correctly, a quality coating adds 10 to 15 years to a commercial roof’s service life. We use materials from leading lines like Iko and Atlas when the job calls for it.

Free Roof Estimate

A free roof estimate is a written quote for the work your roof needs, based on a full inspection, delivered before you pay anything. You need one whenever you’re considering a repair or replacement, or when an insurance adjuster has given you a number and you want a second opinion. At Brennan Roofing Co Dallas, the estimate is the document that starts every job: a line-item price in writing before any work begins. Call (903) 499-4441 and we’ll schedule the inspection.

What the Free Estimate Includes

We inspect the roof, take measurements, and photograph the damage. You get a line-item written quote that shows materials, labor, and scope. Nothing is verbal. Nothing is “we’ll figure it out later.” The price goes on paper before any work starts, and it does not change at the door.

What We Don’t Do

We don’t give quotes over the phone for a roof we haven’t walked. We don’t bury costs in fine print. We don’t start work until you’ve approved the number in writing. If a contractor won’t put the price on paper before starting, walk away.

Brands We Service

We install and service roofing systems from GAF, CertainTeed, and Owens Corning, three of the largest asphalt shingle manufacturers in North America. GAF shingles we install include Timberline and Royal Sovereign lines, and we follow their installation specs exactly so your warranty stays intact. CertainTeed’s Landmark series is a common choice for Dallas homes because it balances cost with a strong hail rating. Owens Corning Duration shingles offer good wind resistance, which matters in Rowlett and Red Oak where storms come fast.

We also work with Tamko and Boral products when a homeowner wants more specific material options. Whether you have GAF, CertainTeed, Owens Corning, Tamko, Boral, or any other roof system, our technicians can inspect, maintain, and repair it. We’ll tell you what’s on your roof, what it needs, and what it’ll cost before we ever pick up a tool.

Signs You Need a Pro Right Now

• Water stains on the ceiling or attic. A stain means water already breached the roof deck. By the time you see it, the leak has likely been active for weeks, and the damage underneath is worse than the stain suggests.
• Missing shingles after a storm. Every missing shingle exposes the underlayment and deck to direct water. In Dallas, summer storms often pair wind with rain within hours, so a shingle gone this morning is a leak by tonight.
• Granules in the gutters. Shingles shed granules as they age. If your gutters are full of granules after a rain, your shingles are reaching the end of their service life. Granule loss accelerates in the Dallas heat.
• Flashing pulling away from chimneys or vents. Flashing is the metal that directs water at roof transitions. When it pulls away, rusts, or cracks, water gets behind it. Most leaks at chimneys and skylights are flashing failures, not shingle failures.
• Daylight through the attic roof deck. If you can see light through the underside of the roof deck, water can see its way in too. This usually indicates cracked decking or failed flashing, and it will not fix itself.
