Why Rochester Homeowners Choose CertainTeed Roofing
We provide independent CertainTeed roofing service in Rochester, NY, for homeowners whose roofs carry CertainTeed Landmark, Presidential, XT or Flintlastic products. What makes our CertainTeed work different is that we’re not a CertainTeed-certified or authorized installer. We’re an independent contractor, so our diagnosis comes from watching what these shingles actually do in Rochester’s freeze-thaw cycles, not from a manufacturer’s sales sheet. Our technicians have up to 10 years of experience, and we read every CertainTeed roof the same way: repair it if the field is sound, replace it if the whole slope is failing.

That independence matters here. Rochester sits in the lake-effect snow and ice-dam belt off Lake Ontario, and the defining roofing problem in this city is winter ice dams and freeze-thaw cycling on older housing stock. A roof that would be fine in Syracuse or Buffalo can fail differently in Rochester because of this city’s own storm track and the density of steep 1920s-50s gable roofs in the older core. Roofers around Rochester spend as much effort on ice-and-water shield, ventilation and attic insulation as on the shingles themselves. If you’re pricing a CertainTeed repair or replacement, call (855) 473-8654.
Why Trust Valor Roof Repair for Your CertainTeed Roofing?
Our technicians know the CertainTeed product families by how they behave, not by a catalog page. Landmark and Landmark Pro architectural shingles, the Presidential Shake and Presidential T/L luxury lines, the three-tab XT 25 and XT 30, and the Flintlastic SA and GTA modified bitumen rolls each fail in a recognizable pattern. We’ve learned to spot those patterns on sight, which is what lets us tell you whether a slope is patchable or worn out.
We use quality parts that fit CertainTeed equipment. Where the shingle is visible, that means matching the existing profile and color with genuine CertainTeed product so a patch doesn’t read as a repair from the street and doesn’t complicate a later warranty discussion. Where brand doesn’t matter, like pipe boots, step flashing and underlayment, we use quality aftermarket materials that hold up to Rochester winters.
Warranty-safe service is the third piece. We don’t make warranty promises on CertainTeed’s behalf, and we won’t tell you a repair preserves coverage we can’t guarantee. What we can do is install and repair in a way that doesn’t create an obvious reason for a manufacturer to deny a claim, and we’ll tell you plainly when that’s the situation. A roof inspection from Valor is a diagnosis, not a sales pitch.

Common CertainTeed Roofing Problems We Fix in Rochester
CertainTeed roofs fail in Rochester for reasons that show up again and again in this climate. Here are the five we see most.
- Seal’n’Grip strips losing adhesion. On Landmark Pro and Presidential roofs, the self-sealing strip can fail to bond through repeated freeze-thaw between November and March. The result is ridge and rake shingles lifting, creasing or peeling back. Once a tab releases, wind gets under it fast.
- Granule loss and asphalt checking on south-facing slopes. The sun-facing side of a Landmark roof ages well ahead of the rest of the roof. Granules wash away, the asphalt checks and cracks, and the slope looks years older than the north side. Summer heat accelerates it, and the exposed mat starts shedding granules into gutters.
- Nail-line cracking and blow-offs on three-tab XT roofs. XT 25 and XT 30 roofs over older, under-ventilated attic decks are prone to cracking along the nail line and shingles blowing off in high-wind thunderstorms. Poor attic ventilation makes the deck run hot in summer and cold in winter, and the fasteners work loose.
- Flintlastic seam and lap failures. On low-slope Flintlastic SA and GTA roofs, the seams and laps open at terminations and around penetrations. Water then tracks under the membrane instead of off it. Spring rain finds those openings quickly, and the leak shows up well away from the actual seam.
- Ice dams backing water under the shingles. On the steep old gable roofs of Rochester’s historic core, ice dams push meltwater up under the shingles. Original board sheathing and under-ventilated attics make it worse. This is why a simple re-roof on those roofs is really a ventilation-and-ice-shield job rather than a shingle swap.
A typical version of this plays out after a windy rain. A homeowner notices a ceiling stain and finds a handful of ridge or rake shingles on a CertainTeed Landmark roof flipped up or missing. The usual cause is the self-sealing strip failing to bond through repeated freeze-thaw, often with a nail set too high or a short starter course at the edge. A qualified pro re-seats or replaces the affected shingles, hand-seals the tabs, checks nail placement and the deck underneath, and repairs the step flashing at the adjacent wall or chimney before calling it done.
CertainTeed Parts & Our Repair-vs-Replace Approach
Choosing parts for a CertainTeed repair comes down to one question: will anyone see it? On a visible slope we match the existing profile and color with genuine CertainTeed shingles. Mixing brands on a visible slope reads badly, and it complicates any later warranty discussion. For the parts nobody sees, like boots, step flashing and underlayment, we use quality aftermarket materials that fit the assembly and survive Rochester’s freeze-thaw. We don’t claim to stock genuine CertainTeed parts or to order them as an authorized source. We source what the job needs.
The repair-or-replace call follows from the same logic. If the CertainTeed field is 15 or more years old with widespread granule loss, or the deck is soft underfoot, quoting a replacement is the honest answer. Selling repeat repairs on a roof that’s already finished just moves the cost around. If the field is sound and the problem is localized to one slope, a valley, or the flashing at a chimney, a targeted repair does the job. Seven brands, one crew, and a recommendation driven by the roof’s condition and your budget, not by what’s easy to install.
If you’re not sure which side of that line your roof is on, call (855) 473-8654 for a free estimate.

Our CertainTeed Service Process – Step by Step
- 1
Diagnosis. We get on the roof, not just look at it from the ground. On a CertainTeed roof that means checking the seal strips, the granule loss pattern, nail placement, deck condition and the attic ventilation driving the ice dams. We tell you what the roof actually needs.
- 2
Repair or install. For a repair, we match the CertainTeed profile and color on visible slopes and hand-seal the tabs. For a replacement, we install with proper ice-and-water shield and ventilation, since that’s what makes a CertainTeed roof last in this climate.
- 3
Check the work. We water-test repaired areas and flashing, confirm the tabs are sealed, and walk the roof line to check that nothing lifted. On a Flintlastic repair we confirm the seams and laps are closed at terminations and penetrations.
- 4
Warranty walkthrough. We hand you the material documentation and explain what it covers and what it doesn’t. We don’t speak for CertainTeed, so we tell you what to ask them directly.

AfterCertainTeed Products We Service & Install in Rochester
We work with the CertainTeed product lines common on Rochester homes. That covers Landmark and Landmark Pro architectural asphalt shingles, the Presidential Shake and Presidential T/L luxury asphalt lines, the XT 25 and XT 30 three-tab shingles, and Flintlastic SA and GTA modified bitumen for low-slope roofs and porch roofs. Leak repair, shingle replacement and flashing repair are the three services we do most on these roofs. We install and service them, we don’t claim to stock them, and we’ll tell you what the roof needs.
On Rochester’s older core, the steep-gable wood-frame houses with original board sheathing are where CertainTeed roofs need the most attention. The shingles usually aren’t the whole story. Ventilation and ice shield are.
We Also Service These Brands
Valor Roof Repair works across seven nationally recognized roofing brands, including GAF and Owens Corning alongside CertainTeed. That breadth means we’re not tied to one manufacturer’s product line, and our recommendation follows your roof’s condition rather than the brand we happen to favor. If your neighbor’s GAF roof needs service or your own CertainTeed roof needs a second opinion, we handle both.
FAQs – CertainTeed Roofing Service in Rochester
No. Valor Roof Repair is an independent contractor and is not a CertainTeed-certified or authorized installer. We service and install CertainTeed products, but we don’t claim manufacturer authorization, and our diagnosis comes from field experience rather than a manufacturer program. Call (855) 473-8654 for a free estimate.
It can, depending on how the repair is done and what the warranty terms say. Improper installation, mixing brands on a visible slope, or nailing that doesn’t match CertainTeed’s requirements can give a manufacturer a reason to deny a claim. We repair in a warranty-safe way, and we’ll tell you plainly when a repair may put coverage at risk. Call (855) 473-8654 to talk through your roof.
Curl at the rakes on Presidential Shake usually means the seal strips have lost adhesion through freeze-thaw, and the answer depends on how much of the field is affected. If it’s a handful of shingles at the rake edge, a targeted repair with matching CertainTeed product and hand-sealing the tabs is often enough. If the whole perimeter is curling and the asphalt is checking, replacement is the honest call. An inspection settles it. Call (855) 473-8654.
Usually yes, if the shingle line is still in production. Landmark and the other CertainTeed lines come in colors, and we match the profile and color so a patch doesn’t stand out from the street. If the color is discontinued, we’ll tell you up front and talk through the options. Call (855) 473-8654 for a free estimate.
Often repairable if the failure is localized to a seam, a lap or a termination around a penetration. Flintlastic SA and GTA seams and laps open at terminations, and water tracks under the membrane. A targeted repair closes those openings. If the membrane is worn across the whole field, replacement is the better answer. Call (855) 473-8654 to find out which one you’re facing.
No. CertainTeed shingles need the same ventilation as any other brand: attic intake and exhaust balanced so the deck doesn’t run hot in summer or cold in winter. What’s different in Rochester is how much it matters. Under-ventilated attics are what feed the ice dams and premature aging on CertainTeed roofs here. Call (855) 473-8654 for a free roof inspection.
Cost depends on the CertainTeed line, the size and pitch of the roof, and how much ice-and-water shield and ventilation the job needs. We quote per job from a written estimate, and the estimate is free. Call (855) 473-8654 for an exact quote, and we’ll walk you through what your roof actually needs.
