Why San Jose Homeowners Choose CertainTeed Roofing
We’re an independent Certainteed service in San Jose, and we repair and replace these systems every week across the South Bay. Most CertainTeed roofs we see in San Jose are Landmark or Landmark Pro architectural shingles on homes built between 1950 and 1980, and the failures are almost always age-related: granule loss from years of intense UV exposure, cracked sealant strips on south-facing slopes, and flashing that has simply outlived its usefulness. We’re not authorized by CertainTeed, and we’ll tell you that plainly. What we offer instead is deep field knowledge of how their products actually perform here, a written price before any work starts, and a workmanship guarantee in writing before the crew leaves your driveway. Call (669) 274-0078 for a free estimate on any CertainTeed repair or replacement.
Why Trust Tilehurst Roofing San Jose for Your CertainTeed Roofing?
Our technicians have devoted thousands of hours to repairing and replacing CertainTeed roofs across San Jose, and that experience matters more than any marketing line. We know where Landmark Pro shingles delaminate first on a Willow Glen ranch house. We know what Presidential Shake TL granule loss looks like when it’s heat-related rather than hail, because we’ve seen both. We know that Flintlastic SA membranes tend to lift at flashing transitions when the original surface prep was rushed, and we check those spots first. That’s the difference between guessing and knowing.
Greg Holloway, who runs Tilehurst Roofing San Jose, picked up his first roofing tools at Los Angeles Trade-Technical College, where instructors made you understand why a tile was set a certain way before they let you near a nail gun. He spent the better part of two decades running crews across San Jose, including a stretch of tile re-roofs near Willow Glen that taught him exactly how South Bay summers and winter rains work on older roofing systems. That experience shapes how we inspect, diagnose, and quote every CertainTeed job. We’re not here to sell you a roof you don’t need. We’re here to tell you what’s actually wrong and what it costs to fix it right.

Common CertainTeed Roofing Problems We Fix in San Jose
- Shingle delamination at the sealant strip on older Landmark lines. South-facing slopes in San Jose take brutal UV exposure for months at a time, and the adhesive strip that bonds shingle tabs together eventually dries out and fails. We routinely find tabs that have lifted completely, leaving the underlayment exposed. This is a wind-driven leak waiting to happen, and it’s a repair we do often in neighborhoods like Blossom Valley and Cambrian.
- Cracked or dislodged RidgeFlex cap shingles along hips and ridges. After high-wind events, the cap shingles that crown the ridge line are the first to go. They crack at the bend point or lift entirely. We replace them with OEM RidgeFlex caps whenever the color is still available, and we check the nails underneath, because a loose cap shingle often means the nail pattern was wrong from the start.
- Blisters and granule loss on Presidential Shake TL. This is a big one in San Jose. The heavy, shake-style profile looks great, but the thick shingle body holds heat. Decades of hot summers cause the asphalt to blister and the granules to slough off. Homeowners sometimes think it’s hail damage. It’s usually not. Heat-related granule loss is progressive, not sudden, and it spreads evenly across the roof rather than showing impact marks.
- Flintlastic SA membrane peeling at flashing transitions. CertainTeed’s self-adhered modified bitumen is a strong product, but it depends on clean, properly primed surfaces at the transitions where the membrane meets metal flashing or parapet walls. When the original install was rushed, those edges lift. Water gets underneath, and you get a slow leak that’s hard to trace. We see this on the low-slope and flat roof sections common on Eichler homes in San Jose.
- Leaking pipe boots that get blamed on the shingles. This is the most common misdiagnosis we correct. The rubber collar around plumbing vent pipes cracks and fails long before the surrounding shingles do, especially in San Jose’s dry heat. The shingles look fine, the ceiling stains don’t. We replace the boot with an OEM collar and reseal the base flashing. In most cases, that solves the leak without touching a single shingle.
CertainTeed Parts & Our Repair-vs-Replace Approach
We use CertainTeed OEM shingles and accessories whenever possible. It’s the right call for two reasons: the visual match matters, and using the manufacturer’s own parts keeps any remaining material warranty intact. For discontinued colors, like the old Weathered Wood Landmark blend that was everywhere in San Jose twenty years ago, we source high-quality aftermarket alternatives that match the existing profile as closely as the current market allows. We’ll show you a sample before we order, and we’ll tell you honestly if the match is close but not perfect.
Our repair-vs-replace stance is simple. If the decking is sound, the underlayment is intact, and the damage is localized, we repair. If multiple slopes are compromised, if the granules are gone across the entire roof, or if the decking underneath is soft, patching is a false economy. You’d be spending money on a roof that’s already past its service life. We’ll show you the evidence either way and give you a written line-item price for both options. Call (669) 274-0078 and we’ll walk the roof with you.
Our CertainTeed Service Process – Step by Step
- 1
Diagnosis. We inspect the entire roof, not just the area you pointed at. On CertainTeed Landmark roofs, we specifically check the sealant strips on south-facing slopes, the ridge caps, the pipe boots, and the flashing. On Flintlastic SA low-slope sections, we check every edge and transition. We document what we find with photos and show you exactly what’s failing and why.
- 2
Repair or replacement. For repairs, we use OEM CertainTeed parts whenever the color is still in production. For replacements, we’ll present you with full material options, including Landmark Pro, Presidential Shake TL, and Northgate ClimateFlex, and explain which performs best on your specific roof pitch and exposure. You get a written price before we order a single shingle.
- 3
Testing. After the work is done, we water-test repairs where it’s practical, and we walk the roof with you so you can see the finished work up close. We don’t leave until you’ve had a chance to ask questions.
- 4
Written guarantee. Before we leave, you get a written guarantee for the repair or installation. That’s not a phone call later, not a promise, not an email. It’s paper in your hand. If the repair fails inside the guarantee period, we return at no charge under our 365-Day Done Right Promise.

AfterCertainTeed Products We Service & Install in San Jose
We work on the full range of CertainTeed residential roofing products: Landmark and Landmark Pro architectural shingles, Presidential Shake TL, Northgate ClimateFlex, and Flintlastic SA self-adhered modified bitumen for low-slope and flat roof sections. We also handle the supporting accessories: RidgeFlex cap shingles, WinterGuard ice and water shield, starter strips, and hip-and-ridge products. We keep common OEM accessories in local stock for fast turnaround on repairs, and we can source full roof quantities quickly through our supplier network. When a Fremont Certainteed service call comes in or a San Jose roof needs attention, we can usually diagnose it the same day and have the written estimate in your hands within 24 hours.
We Also Service These Brands
Tilehurst Roofing Company is a multi-brand company, and that’s deliberate. We don’t push one manufacturer’s product just because it happens to be on the truck. Alongside CertainTeed, we service and install GAF and Owens Corning systems, and we carry five additional manufacturer lines so the material fits the home. A Willow Glen ranch and an Almaden two-story don’t need the same roof. We’ll quote you the option that makes sense for your specific structure, not our inventory.
FAQs – CertainTeed Roofing Service in San Jose
No, we’re not. We’re an independent CertainTeed service provider. We repair and replace their products every week across San Jose, and we know their systems deeply, but we are not affiliated with or authorized by CertainTeed itself. That independence means we can give you a straight answer about whether a repair or a replacement is the right call, without any manufacturer pressure shaping the recommendation. Call (669) 274-0078 and we’ll tell you what we’d do if it were our roof.
Yes, whenever the product line and color are still in production. We use OEM CertainTeed shingles, RidgeFlex caps, starter strips, and pipe boot collars to preserve the visual match and any remaining material warranty. For discontinued colors or older product lines, we’ll source a high-quality aftermarket match and show you a sample before we order. You’ll know exactly what’s going on your roof before it goes on, and the price is in writing first.
Most targeted repairs, such as shingle replacement, leak repair, or flashing repair, are done in a single visit. Larger repair scopes or full replacements take longer depending on the roof size and the condition of the decking underneath. We’ll give you a clear timeline with your written estimate, and we show up in the window we gave. In San Jose, where tear-offs in neighborhoods like Blossom Valley often involve shingles that have fused together from decades of sun, we’ll also tell you upfront if the labor will run higher than a standard tear-off. Call (669) 274-0078 to schedule a free estimate and we’ll give you exact numbers.
We service and install the entire residential CertainTeed lineup in Certainteed in Santa Clara and throughout the area: Landmark, Landmark Pro, Presidential Shake, Presidential Shake TL, Northgate ClimateFlex, and Flintlastic SA. We also handle all the accessories: RidgeFlex cap shingles, WinterGuard ice and water shield, starter strips, and vent products. Whether you have a 2003 Landmark roof with a few blown tabs or a Flintlastic SA flat section that’s lifting at the parapet, we know where to look and we’ll fix it correctly.
Repairs done with OEM CertainTeed materials by a qualified contractor generally do not void the manufacturer’s material warranty, but the specifics depend on your warranty terms and the nature of the repair. We’re happy to walk you through what your warranty actually covers, which is often less than homeowners expect. Our workmanship guarantee is separate and in writing, and it covers our labor for a full year under the 365-Day Done Right Promise. Give us a call at (669) 274-0078 and we’ll take a look at your roof and your paperwork.
It depends entirely on scope. A targeted repair, like a leaking pipe boot or a few missing shingles, typically runs $300 to $600. More involved repairs, like flashing replacement at multiple penetrations or re-capping a long ridge line, can run $800 to $1,500 or more. A full CertainTeed roof replacement in San Jose generally starts around $15,000 for a typical 1,800-square-foot ranch and goes up from there based on pitch, tear-off difficulty, decking condition, and the product line you choose. Landmark Pro costs more than standard Landmark, and Presidential Shake TL costs more than either. We’ll give you an exact written line-item price after we walk the roof. Estimates are free. Call (669) 274-0078.
Sometimes, yes. CertainTeed has discontinued several Landmark colors over the years, and the old Weathered Wood blend is one we get asked about regularly in San Jose. There are aftermarket shingles made to approximate those older blends, and we’ll order samples and bring them to your home so you can judge the match yourself before we install anything. We’ll also tell you honestly if the match is close but not perfect. If you’re patching a small section, that’s usually fine. If you’re thinking about a partial re-roof, you may be better off doing the full roof while you can still find a close match. Call (669) 274-0078 and we’ll bring samples to your door.
That pattern usually points to a specific microclimate issue on your property. The northwest slope may be catching more afternoon sun in your specific orientation, or it may be partially shaded by a tree that holds moisture longer, creating more thermal cycling. It can also be a sign that the original install on that slope had a defect, or that the shingles there are from a different production batch. We’ll inspect the slope’s exposure and compare granule loss patterns across the whole roof before we give you an answer. Call (669) 274-0078 for a free inspection.
We do both. WinterGuard is a self-adhered membrane typically installed at the eaves, in valleys, and around penetrations. In San Jose, it rarely sees the ice damming it was designed for, but it does age, dry out, and lose adhesion over time. When we’re replacing shingles in those areas, we inspect the WinterGuard underneath and replace it if it’s brittle or lifted. If your roof is leaking at an eave or valley and the WinterGuard is the culprit, we’ll tell you exactly what needs to come up and what the fix will cost before we start. Call (669) 274-0078 for a free estimate.
Cracks along the keyways of Presidential Shake TL shingles are usually thermal stress fractures. The thick shake profile expands and contracts more than a thinner architectural shingle, and over years of San Jose heat, the material flexes at its weakest points. Keyway cracks can let water through, but they don’t always compromise the entire roof. We repair individual cracked shingles when the surrounding area is sound, and we’ll tell you if the cracking is widespread enough that replacement is the smarter long-term call. Call (669) 274-0078 and we’ll inspect your roof and give you both numbers.
Yes. Parapet wall transitions are the most common failure point we see on Flintlastic SA roofs in San Jose, especially on Eichler homes. The membrane lifts when the original primer or surface prep was inconsistent, and once water gets behind it, the problem spreads. We’ll strip back the lifted section, re-prime the surface correctly, install new Flintlastic SA membrane, and seal the flashing with the proper detail work. It’s a repair we’ve done many times, and we’ll put the guarantee in writing before we leave. Call (669) 274-0078 for a free estimate.
