CertainTeed Roofing in Garland, TX | Brennan Roofing Co Dallas
Our Garland Roofing Company provides independent CertainTeed roofing service across Garland, from full replacements to surgical repairs on Landmark, XT, and Presidential systems. The thing that makes our CertainTeed work here different is simple: we know what east-side hail does to these specific shingle lines on Garland’s 1960s and 70s ranch homes, and we price the fix honestly instead of pushing a full tear-off when a slope replacement will do. Call (903) 499-4441 for a written estimate before any work starts.
Why Garland Residents Choose Us for CertainTeed Service
CertainTeed is not one product. It’s a family of shingle systems, each with its own nailing strip, granule blend, and wind rating. Travis Oakley, our owner, learned roofing at Los Angeles Trade-Technical College and has spent decades putting on roofs across the Southwest. He trains every tech to understand the difference between an XT 25 3-tab and a Landmark architectural shingle before they ever touch a Garland roof.
We’re an independent CertainTeed service provider. Nobody pays us to push their product line, and we’re not manufacturer-authorized in the sense of being a captive dealer. That independence matters when a repair is smarter than a replacement. We’ll tell you the truth about what your roof needs and put the price on paper before any work begins. Our CertainTeed sales & service work across the region follows the same standard.
Every technician on a Brennan Roofing job is background-checked and arrives in uniform. The Garrison Standard applies to every job: written price before any work starts, and a 365-Day Done Right Promise in writing for one full year. If a repair fails within that year, we come back at no charge.

Common CertainTeed Roofing Problems We Solve in Garland
- Granule spatter loss on aging XT 25 3-tab shingles. After a March-to-June hailstorm, older XT roofs north of I-30 and around Duck Creek often show granules beaten down to the mat while the eaves look fine. That’s not a warranty claim that’s going anywhere on a roof past its service life. We’ll tell you when a slope replacement makes more sense than chasing patches.
- Wind-driven ridge cap separation on Landmark architectural systems. The newer homes in Firewheel and Springpark have steeper roof profiles, and ridge cap sealant strips cure brittle after years of Texas sun. High wind gets under the cap, and suddenly you have exposed nail heads along the ridge. We replace caps with CertainTeed OEM hip-and-ridge components that actually match.
- Cracking at the nail line on Landmark shingles over poorly vented decks. Plenty of 1970s ranch homes in Garland have attic airflow that was never right from day one. Heat builds up, the deck gets hot, and shingles crack right along the fastener line. We flag the ventilation problem when we see it, because replacing shingles without fixing the airflow just sets you up for the same failure.
- Delamination on Landmark Pro over low-slope patio roofs. Some Garland ranch homes have patio additions with slopes that shed water too slowly. Water hangs around, the layers start separating, and the shingle looks swollen along the edge. That’s a design problem as much as a material problem, and we’ll say so.
- Leaking valleys and failed step flashing at chimneys and walls. On older Garland homes, the valley metal and step flashing were installed decades ago and are now rusted through. We bend new flashing, replace valley liners, and use CertainTeed starter strips where the repair calls for them.
CertainTeed Service in Garland: What Local Conditions Mean for Your CertainTeed Roof
Garland sits on the eastern edge of the Dallas-Fort Worth metroplex, right in the path of the I-30 hail corridor. That location changes how CertainTeed roofs fail here compared to cities like Plano or Richardson, where tree canopy often breaks hail before it hits the north-facing slopes. In Garland, a bonded-and-insured CertainTeed XT roof installed before 2005 is frequently missing granules on the north slope first, because that’s the side the hail hits hardest and the side the afternoon sun has already been breaking down for years.
What does that mean for you as a Garland homeowner? It means a roof that looks fine from the street may be half-dead on the side you can’t see. It also means insurance adjusters who know Garland will look for spatter on the north slope first. Our inspections start there too. We don’t wait for a leak to tell you the roof is gone. We walk the slope, photograph what we find, and give you a straight answer about what needs work and what doesn’t. In our Garland service area, that honest assessment is the whole point.
CertainTeed Models & Products We Service in Garland
We work on CertainTeed XT 25 3-tab, Landmark architectural, Landmark Pro, and Presidential Shake systems. Each one has its own granule blend and color lot, which is why we prefer CertainTeed OEM shingles and accessory components like hip-and-ridge caps, starter strips, and leak barriers when doing partial repairs. Matching the granule blend matters on a patch repair; a mismatched slope looks bad and ages differently.
If an older XT or Landmark line has been discontinued and a full replacement is the honest answer, we’ll tell you that instead of patching with shingles that don’t match. We keep common CertainTeed accessory components stocked for fast Garland turnaround, and we’ll order the specific color lot we need for your roof so the repair doesn’t stand out like a sore thumb.

FAQs – CertainTeed Roofing in Garland
XT 25 shingles are an older 3-tab design, and the granule adhesion bond breaks down after 15 to 20 years. On Garland’s east side, hailstorms hit the north slope hardest, and that’s where you’ll see spatter down to the mat. Newer architectural shingles have a thicker mat and better granule retention. If your XT is past 15 years old and showing widespread spatter, a slope replacement with Landmark architectural shingles usually makes more sense than chasing individual shingle patches. Call (903) 499-4441 for an honest assessment.
Yes. Firewheel and Springpark homes have steeper roof profiles, which puts more uplift pressure on the ridge line. The sealant strip on the cap shingles cures brittle in the Texas heat, and once the wind gets under it, the cap starts peeling. Older Garland ranch homes have lower slopes and less ridge line exposure. We replace ridge caps with CertainTeed OEM components and check the sealant bond during every Garland inspection. Call (903) 499-4441 for a ridge cap evaluation.
Usually yes. A valley leak is often caused by rusted valley metal or failed shingle overlap in the valley itself, not by a failure across the entire slope. We can remove the shingles in the valley, replace the liner with new metal, and re-shingle that area with matching CertainTeed material. It’s a targeted Garland Roof Repair that costs far less than a full slope replacement. Call (903) 499-4441 and we’ll inspect the valley and give you a written price before any work starts.
That’s almost always a deck ventilation problem, not a shingle defect. Garland summers push attic temperatures past 130 degrees, and if your 1970s ranch home has poor airflow, the deck gets so hot that shingles crack right along the fastener line, which is the stress point. We’ll inspect your attic ventilation while we’re on the roof. Fixing the airflow is as important as replacing the cracked shingles. Call (903) 499-4441 for an inspection that looks at the whole system, not just the shingles.
Probably not. CertainTeed shingles are rated for specific minimum slopes, and if the addition was built below that pitch, the manufacturer won’t cover wind loss. The real fix is either adding a peel-and-stick membrane under the shingles or switching to a low-slope roofing system like modified bitumen. We’ll tell you which one makes sense for your situation and put the number on paper before any work begins. Call (903) 499-4441 for a straight answer.
