CertainTeed Roofing in Dallas, TX | Mercer Roofing Co Dallas
We provide independent CertainTeed roofing repair and replacement across Dallas, from Lake Highlands to Oak Cliff, as a trusted Dallas Roofing Company. What sets our CertainTeed work apart here is that we know exactly what Metroplex hail does to these shingles because we see it every spring. Whether it’s impact fractures on Landmark shingles or thermal cracking on older XT 25 roofs, we restore these systems without manufacturer involvement. Call (432) 302-5605 for a free estimate.
Why Dallas Residents Choose Us for CertainTeed Service
Our crews work on CertainTeed roofs across Dallas every week. That repetition matters. A roofer who only touches CertainTeed occasionally misses the failure patterns that show up after a March hailstorm or an August heat wave. We don’t. Grant Whitlock, our owner, came up through a tear-off crew in Los Angeles and completed the construction technology program at Los Angeles Trade-Technical College before spending nearly two decades on roofs across the Southwest. He’s now put on hundreds of roofs from Oak Cliff to Far North Dallas, and he’s known for telling homeowners what their roof actually needs versus what it doesn’t. When you call us about a CertainTeed roof, you get that same straight talk. For broader coverage of our CertainTeed work, see our CertainTeed sales & service page.

Common CertainTeed Roofing Problems We Solve in Dallas
- Hail impact fractures on Landmark shingles. Spring storms from March to June drop hail that cracks the granule layer straight through to the asphalt mat. Once that mat is exposed, water gets in. We replace the damaged shingles and check the underlayment beneath them.
- Blistering and thermal cracking on XT 25 3-tab shingles. Dallas summers push attic temperatures past 140°F on poorly ventilated ranch-style homes. Those 3-tab shingles bubble, then crack. We often find the real problem is intake ventilation, not the shingle itself.
- Flashing and valley leaks on Presidential Shake. That heavier, textured profile expands and contracts against metal flashing during Dallas temperature swings. Over a few years, the seal fails and water follows the valley. We inspect the flashing first, not last.
- Granule loss and premature aging on Northgate shingles. High UV exposure on low-slope Dallas roofs accelerates granule loss, and repeated hail events make it worse. Once granule loss is widespread, the roof is nearing replacement.
- Rotted decking under hail-damaged shingles. Hail cracks let water sit on the plywood decking. By the time we tear off, we frequently find soft spots on south-facing slopes that bake in the Dallas sun after every storm.
CertainTeed Service in Dallas: What Local Conditions Mean for Your Roof
In Dallas’s Lake Highlands neighborhood, entire blocks of 1970s ranch homes often show three or four different shingle colors within a few hundred feet after a hailstorm. That’s a direct result of staggered insurance claims, neighbors file at different times, adjusters approve at different rates, and roofs get replaced piecemeal over two or three years. For us, that means our CertainTeed crews routinely match new Landmark shingles to older, sun-faded sections rather than just tearing everything off. A homeowner might only need the storm-damaged slope replaced, but the new shingles arrive brighter than the ones that have sat under Texas sun for eight years. Matching that color takes knowing the CertainTeed product line, understanding how Landmark fades in Dallas UV, and sometimes pulling shingles from less visible roof planes to blend the repair. That’s not a skill you learn from a brochure. It comes from doing the work on actual Lake Highlands roofs, on actual Ferndale Road claims, and seeing how the colors settle over a season. If you’re in our Dallas service area, you get that experience on every job.
One job sticks with us. A hailstorm claim on Ferndale Road in Lake Highlands brought us to a 2003 Landmark roof that had lost large patches of granules and several shingles cracked straight to the mat. The adjuster approved replacement, and our crew tore off the damaged sections, replaced rotted decking on the south slope, and installed new Landmark Pro shingles with upgraded underlayment. Insurance covered the whole job. We color-matched the new shingles to the less-damaged north-facing slope so the house didn’t end up looking like a patchwork quilt. That’s the level of detail Dallas Roof Repair claims demand.
CertainTeed Models & Products We Service in Dallas
We service the full CertainTeed residential lineup: the Landmark series (Landmark, Landmark Pro, Landmark Premium), XT 25 3-tab shingles, Presidential Shake, and Northgate for multi-family and production builds. We default to genuine CertainTeed replacement shingles and accessories to maintain color match and warranty continuity where possible. But we’ll use proven aftermarket flashing, vent boots, and underlayment when OEM parts are overpriced or no longer made. We keep common Landmark colors and flashing profiles stocked for fast Dallas turnaround, so a repair that needs a specific shingle color doesn’t stall for a week while parts ship from a distributor.

FAQs – CertainTeed Roofing in Dallas
Yes, we can match new Landmark shingles to sun-faded sections in most cases. Sun exposure on Dallas roofs fades shingles unevenly, especially on south and west slopes, so we sample from the existing roof and match close tones from the Landmark line or pull shingles from less-visible planes to blend. It’s never a perfect match after years of UV, but we get close enough that the repair doesn’t announce itself from the street. Call (432) 302-5605 and we’ll look at your roof before quoting.
Yes, we work directly with insurance adjusters on Dallas storm claims. We document the hail or wind damage, meet the adjuster on-site when possible, and provide line-item repair or replacement scopes they can approve. The Ferndale Road job we mentioned earlier was fully covered by the homeowner’s policy because we documented every damaged section before the adjuster arrived. That documentation matters, and we do it as standard practice.
We’ll replace XT 25 with XT 25 when that’s what the roof calls for and the product is still available. We don’t push architectural shingles on customers who don’t need them. That said, many Dallas homeowners with XT 25 roofs are seeing thermal cracking and blistering that a 3-tab product simply can’t survive long-term in this heat, and we’ll tell you honestly if a Landmark architectural shingle would serve you better. The choice stays yours, and the written price reflects whichever product you pick.
Presidential Shake leaks at the valleys usually come from expansion and contraction of the heavier shingle profile against metal flashing during Dallas temperature swings. The sealant at the flashing edge breaks down, and water follows the valley instead of shedding over it. We fix it by pulling the valley flashing, re-sealing with proper materials, and sometimes installing wider flashing to accommodate the movement. It’s a known failure mode with this product in this climate, and it’s repairable when caught early. Call (432) 302-5605 for a free inspection if you’re seeing valley leaks.
Yes, isolated blistering is repairable by replacing the affected shingles, usually $350 to $900 depending on how many are involved and the roof’s pitch. But if blistering covers a large area, the roof is telling you the decking isn’t venting properly. In that case, replacing blistered shingles alone buys you time, not a solution. We’ll inspect the attic ventilation before recommending a repair-only approach, because on Dallas ranch homes with box vents, the ventilation deficiency is often the real cause.
