Why Dallas Homeowners Choose CertainTeed Roofing
Brennan Roofing Co Dallas provides independent Certainteed in Dallas roofing repair, replacement, and inspection across Dallas, TX. We’re not a CertainTeed-authorized dealer, and we won’t pretend to be. What we are is a local crew that has installed and repaired CertainTeed shingle, metal, and tile systems in North Texas for over a decade, including Landmark, Landmark Pro, Presidential Shake, and Grand Manor lines. We know how these products fail in Dallas heat and hail because we’ve been on hundreds of those roofs. Call (903) 499-4441 for a written estimate before any work starts.
Why Trust Brennan Roofing Co Dallas for Your CertainTeed Roofing?
CertainTeed makes good roofing materials. But a shingle is only as good as the crew that puts it on and the flashings around it. Our technicians know the difference between a Landmark shingle that’s been nailed too high and one that’s been nailed too low. They know how Presidential Shake tiles react to a North Texas summer and what Grand Manor ridgelines do when temperatures swing forty degrees in a day. That’s the kind of knowledge you only get from years of hands-on work with the product, not from a training video.
Travis Oakley, our owner, grew up in Los Angeles and learned the roofing trade at Los Angeles Trade-Technical College. He spent decades putting roofs on across the Southwest before bringing his crew to Dallas. He keeps a worn copy of the local building code in his truck. When a CertainTeed repair comes through, he’s often standing on the roof himself, checking nail patterns and seam seals before we ever write the price down. That’s just how he works. A roof either keeps water out or it doesn’t, everything else is just conversation.
Every job we do operates under The Garrison Standard: a written price before any work starts, background-checked uniformed technicians on site, and a 365-Day Done Right Promise in writing. If a repair fails within a year, we come back free. No charge. That promise applies to every CertainTeed repair and installation we perform in Dallas and nearby communities like Certainteed in Mesquite.

Common CertainTeed Roofing Problems We Fix in Dallas
CertainTeed roofing holds up well when installed correctly. But Dallas weather has a way of finding the weak points. Here are the failure patterns we see most often on CertainTeed roofs in this city and neighboring Certainteed in Garland:
- Hail impact fractures and granule loss on Landmark shingles. Dallas sits in Hail Alley. Spring storms drop stones the size of golf balls and bigger. Landmark shingles take the impact, and the granules that protect the asphalt mat get knocked loose. Within months, those spots start to show bare asphalt. Two or three years later, the shingle cracks through. We see this on roofs in Lake Highlands and Richardson after almost every major spring storm. Small granule loss is cosmetic. Large bald patches mean the shingle’s protection is gone and it’s time for targeted replacement.
- Wind uplift and blow-off on Landmark shingles with improper nail patterns. The nail placement is everything on a shingle. CertainTeed publishes a nail zone that runs along the shingle’s reinforcement strip. When the nails are driven above that zone, especially on roofs with original 1990s tract housing construction, the shingle doesn’t grip the decking the way it should. A strong straight-line wind from a North Texas thunderstorm lifts the shingle tab and folds it back. We repair these by stripping the damaged course and replacing the shingles with nails in the right position. Sometimes the whole roof needs a fastener audit if the blow-offs are scattered.
- Cracking and brittleness in Presidential Shake tiles from prolonged UV exposure. Presidential Shake is a heavy, multi-layer product designed to mimic wood shakes. But the UV in Dallas is relentless. After twelve or fifteen summers of direct sun, the tiles can lose their flexibility and start to crack at the edges. This shows up most on south-facing and west-facing slopes. Cracked tiles need replacing, not sealing. Sealing a brittle tile just traps the problem behind a cosmetic patch.
- Flashing and valley leaks at Grand Manor ridgelines due to thermal expansion. Grand Manor is a heavy architectural shingle with deep shadow lines. The ridge cap and valley metal on these roofs expand and contract with Dallas’s daily temperature swings, which can be forty degrees between night and afternoon. Over years, that movement works the metal loose at the seams and nail heads. Water follows gravity into the gap. We replace the flashing, reseat the valley with new underlayment, and rework the ridge cap so the metal can move without pulling free.
- Chimney step flashing failures on any CertainTeed shingle line. This one isn’t about the shingles, it’s about the flashing that transitions between the roof slope and the chimney. The original step flashing on many Dallas homes from the 1970s through 2000s was galvanized steel. It corrodes. Once the step flashing is shot, the shingles around the chimney are usually suspect too. We strip back the shingles, inspect the underlayment, install new flashing, and lap new CertainTeed shingles over it in the correct sequence.
CertainTeed Parts & Our Repair-vs-Replace Approach
When we repair a CertainTeed roof in Dallas, we prioritize CertainTeed OEM shingles, underlayment, and flashing. The shingle’s color blend, the adhesive strip, and the mat weight all need to match what’s already on the roof. CertainTeed produces specific color codes for each Landmark and Landmark Pro blend, and we stock the most common Dallas colors locally so repairs don’t wait on a distributor run. When OEM metal components aren’t available or the cost doesn’t pencil out for the homeowner, we use quality aftermarket step flashing and drip edge. Those components don’t affect the shingle warranty, and a good galvanized aftermarket flashing will outlast most original installs.
We recommend replacement over repair when two things are true: the decking under the shingles is compromised, or the shingles have passed roughly 80% of their rated service life. If a Landmark roof is fifteen years old and showing granule loss across three slopes, patching individual shingles buys time but doesn’t change the trajectory. We’ll tell you that straight. If the decking is solid and the shingles have life left, a targeted repair with matching OEM shingles is the honest call. Call (903) 499-4441 and we’ll put the numbers on paper either way.
Our CertainTeed Service Process – Step by Step
We don’t do surprise inspections. Every CertainTeed service call in Dallas follows the same four steps:
- 1
Diagnosis. We walk the roof, check the slopes, the valleys, the flashings, and the decking from the attic side when we can. For CertainTeed shingles, we’re looking at nail placement, granule condition, and adhesive strip engagement. Travis or a lead tech confirms the diagnosis before anything gets written down.
- 2
Written price. You get the number on paper before any work starts. That price includes the specific CertainTeed shingles or components we’re using, the labor, and any disposal. It does not change at the door. This is The Garrison Code, and we don’t make exceptions.
- 3
Repair or installation. Technicians arrive in uniform, background-checked, and do the work to the manufacturer’s installation spec. For CertainTeed shingles, that means nails in the reinforced nail zone, correct exposure, and proper overlap at valleys and ridges.
- 4
Test and warranty. We water-test the repair where practical, inspect the finished work, and leave the site clean. Then we give you the 365-Day Done Right Promise in writing. If it fails within a year, we come back free. No cost, no argument.

AfterCertainTeed Products We Service & Install in Dallas
We work on the full residential CertainTeed line, with the most experience in these four: Landmark, the standard architectural shingle that covers more roofs in Dallas than any other CertainTeed product; Landmark Pro, the heavier-grade architectural shingle with a larger nail zone and higher wind rating; Presidential Shake, the multi-layer luxury shingle; and Grand Manor, the heavyweight architectural shingle with deeper shadow bands. We stock common Landmark and Landmark Pro color blends locally for faster repair turnaround. Presidential Shake and Grand Manor colors are ordered per job, and we confirm the exact color code against the existing roof before ordering.
We Also Service These Brands
We install and repair CertainTeed because Dallas homeowners ask for it specifically. But we’re not tied to one manufacturer. We work with GAF, Owens Corning, IKO, Atlas, Tamko, and Boral. If your current roof is a different brand, or you’re weighing CertainTeed against GAF’s Timberline or Owens Corning’s Duration, we’ll walk you through the differences without a sales pitch.
FAQs – CertainTeed Roofing Service in Dallas
Hailstones in Dallas routinely exceed an inch in diameter, and when they hit a Landmark shingle at speed, they dislodge the ceramic granules that protect the asphalt mat underneath. One storm can strip granules from hundreds of shingles across a roof. The bald spots that appear later are where the asphalt is now exposed to UV and moisture, which accelerates cracking. We assess the extent of the loss and replace the most damaged shingles with matching CertainTeed Landmark in the same color blend. Call (903) 499-4441 for a written repair estimate.
Look for ridge cap pieces that are lifted, cracked, or missing altogether. Presidential Shake ridge caps are thicker than standard caps, which makes them heavier but also more prone to showing damage at the seams when a strong wind hits the ridge line. If you can see nails or the cap pieces are out of alignment, the ridge has taken a hit. We inspect the ridge, replace damaged caps, and check the underlying fasteners before resealing. If you’re not comfortable getting on a ladder, call (903) 499-4441 and we’ll do the inspection.
Yes. CertainTeed assigns a specific color code to every blend in the Landmark and Landmark Pro lines. We identify the code on your existing shingles, either from the original paperwork if you have it or from matching the physical shingle against CertainTeed’s current color boards. We stock the most common Dallas blends and order the rest. A visibility-off match is something we get right, because a patch that doesn’t match is a repair we’d have to come back and redo under our 365-Day Done Right Promise. Call (903) 499-4441 and we’ll identify your color code.
Grand Manor valleys fail because the valley metal and the underlayment expand and contract at different rates through Dallas’s hot days and cooler nights. Over years, that differential movement breaks the seal at the valley edges. Water gets under the shingles and follows the valley line into the house. We fix it by stripping back the shingles at the valley, inspecting the valley metal, replacing it if it’s corroded or warped, and reinstalling with fresh CertainTeed underlayment before the shingles go back down.
Steep-pitch roofs take more direct hail impact per shingle because the angle of the roof meets the falling hailstone more squarely. If your steep-pitch Landmark roof is over ten years old and the hail damage is widespread, replacement is usually the better financial call. If the damage is isolated to one or two slopes and the shingles still have granule coverage elsewhere, targeted repair with matching Landmark shingles is the honest choice. We’ll give you both numbers in writing. Call (903) 499-4441 for a free estimate.
CertainTeed roofing repair in Dallas typically runs $350 to $900 for minor leak repairs and shingle replacements, while full Landmark roof replacement on an average Dallas home runs $9,000 to $16,000 depending on square footage, pitch, tear-off, and decking condition. Landmark Pro and Presidential Shake run higher per square. You’ll get a precise written price before any work starts, and that price won’t move at the door.
