CertainTeed Roofing in Montclair, CA | Orange County Roofing Co
We provide independent CertainTeed sales & service across Montclair, from full tear-offs and re-sheets to tile underlayment replacement and shingle repair. What makes our CertainTeed work different here is simple: we know what these roofs actually do in 100°F Inland Empire heat, and we plan every assembly around it. If your CertainTeed roof is cracking, leaking, or just looking tired after years of Montclair sun, call (866) 942-4187 for a free estimate.
We’re not a CertainTeed dealership. We’re a roofing company that installs and services CertainTeed products among seven major manufacturers we carry, which means our recommendation comes from what your Montclair home actually needs, not from a brand quota. Kurt Hensley, our owner, has spent two decades on roofs across Orange County and the Inland Empire, and he’ll tell you the same thing on every job: a roof shouldn’t be a mystery – let’s just look at what you’ve got and go from there.
Why Montclair Residents Choose Us for CertainTeed Service
CertainTeed makes a lot of different products: Landmark architectural shingles, Presidio concrete tile, Flintlastic SA peel-and-stick underlayment. Each one has its own installation specs and its own way of failing in Montclair’s climate. Our crew has torn off and rebuilt hundreds of CertainTeed roofs across the Inland Empire, from Landmark shingles on 1970s tracts to Presidio underlayments on newer builds. We know how CertainTeed products actually age in 100°F heat, and we specify every assembly to match the brand’s published installation requirements, without ever claiming to be authorized, sponsored, or warranty-backed by CertainTeed.
That independence matters when you’re making a five-figure decision. We carry seven major brands – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, Boral – so when we recommend a CertainTeed product, it’s because it’s the right material for your roof, backed by the manufacturer’s own warranty. Not because it’s the only thing on the truck.
Kurt grew up in the Serrano Heights area of Orange and spent his summers watching crews work the tile roofs on the hillside homes. That’s what got him hooked on the trade before he ever picked up a nail gun. He completed construction technology coursework at Santiago Canyon College, then spent the better part of two decades working roofs before launching Orange County Roofing Co. He brings that same straight-answer approach to every Montclair job.

Common CertainTeed Roofing Problems We Solve in Montclair
These are the five issues we see most often on CertainTeed roofs in Montclair:
- Landmark shingles cracking and losing granules on west- and south-facing slopes. Montclair summers routinely push past 95-100°F with very low humidity. That UV bake hits Landmark shingles hard, especially after 15-20 years. The granules loosen, the asphalt dries out, and you’ll see cracking before the rest of the roof looks bad. We catch this early with a standalone inspection and repair just the affected slopes when the roof still has life left.
- Original wood-shake tear-offs exposing rotted decking over skip sheathing. This is the big one in Montclair’s older tracts off Holt and Ramona. The original wood-shake roofs were often laid over skip sheathing with no underlayment. By the time you’re putting on a CertainTeed replacement, the deck underneath is frequently rotted and must be re-sheeted before any new shingle or tile assembly can go on.
- Presidio tile systems failing at the underlayment, not the tile. The concrete tile itself holds up fine in Montclair heat. What fails first is the felt or peel-and-stick beneath it, which dries out and tears at flashings and valleys. We replace those underlayments independently, without pulling off good tile unnecessarily.
- Flintlastic SA underlayment wrinkling and pulling at terminations on flat patio additions. Montclair’s post-war tract homes often have flat or low-slope patio additions that need different membrane systems. When attic temperatures spike in summer, Flintlastic SA can wrinkle and pull, especially if the original install skipped a proper cap sheet. We see it regularly on 1950s and 1960s homes throughout Montclair.
- Worn flashings that hold up fine until the winter storms hit. Montclair doesn’t get much rain, but when the Pacific sends a storm system through, the dry, cracked flashings on aging CertainTeed roofs become the first leak point. We recommend checking flashings before the season, not after water’s coming through the ceiling.
CertainTeed Service in Montclair: What Local Conditions Mean for Your Equipment
Here’s something that changes how we approach nearly every CertainTeed replacement in Montclair and won’t apply the same way in Rancho Cucamonga or Mead Valley. In the older tracts off Holt and Ramona, original wood-shake roofs were commonly laid over skip sheathing with no underlayment. Skip sheathing means the deck is spaced boards, not solid plywood. No underlayment means there’s nothing between the wood and whatever’s on top. When we tear off one of those roofs to install CertainTeed Landmark shingles or Presidio tile, we almost always find rotted decking in the valleys and around penetrations. You can’t lay a manufacturer-specified CertainTeed assembly over rotted, spaced boards. So the job becomes a full tear-off, a full re-sheet with new OSB or plywood, then the CertainTeed system on top. Homeowners who’ve budgeted for a standard replacement often don’t see that re-sheet coming, and it adds real cost and time. We flag it during the estimate so you’re not surprised later. We’ve been doing CertainTeed sales & service long enough to know that in Montclair, the deck is the project more often than not.
One example sticks with us. On a 1962 tract home near Holt and Ramona, our crew tore off a worn wood-shake roof and found the skip sheathing had rotted through in two valleys. We re-sheeted the entire deck with new OSB, then installed a CertainTeed Landmark Solaris cool-rated shingle system with new flashing and ridge vent as part of our Claremont CertainTeed service approach. The attic temperature dropped noticeably, and the homeowner finally had a roof that could handle Montclair’s summer without cooking the house.
CertainTeed Models & Products We Service in Montclair
We work on the full CertainTeed residential lineup you’re likely to find in Montclair:
- Landmark architectural shingles, including Landmark Solaris cool-rated shingles that reflect more UV and help keep attic temperatures down.
- Presidio concrete tile, common on newer builds and re-roofs where homeowners want tile aesthetics without clay’s weight.
- Flintlastic SA peel-and-stick underlayment, specified on low-slope patio additions and under tile systems.
- CertainTeed-branded accessories – starter strips, ridge caps, and Flints – where they’re part of the specified system.
Parts matter, and we’re straight about them. We use CertainTeed-branded accessories where the system calls for them, and high-quality aftermarket flashings, boots, and fasteners where they meet or exceed the same standard. You’ll always know which is which, because we tell you. For fast Montclair turnaround, we keep common CertainTeed components on hand, so a typical repair doesn’t wait on a supplier run.

AfterCertainTeed Service Pricing in Montclair
Most Montclair homeowners calling about CertainTeed work are asking one of two things: how much is a repair, and how much is a replacement. Here’s what shapes the number:
Repairs: Shingle replacement, flashing repair, or underlayment patching on a CertainTeed roof in Montclair typically runs $400 to $1,200, depending on the slope, accessibility, and how many layers we’re working through — similar to our CertainTeed repair in Ontario pricing. A simple Landmark shingle patch on a single-story tract home costs less than a valley rebuild on a two-story.
Full replacements: A complete CertainTeed Landmark replacement in Montclair, including tear-off, decking repair as needed, and new flashing, generally ranges from $12,000 to $28,000. Presidio tile runs higher. The wildcard in Montclair specifically is that re-sheet: if your home off Holt or Ramona still has the original skip sheathing, the decking replacement adds meaningfully to the job.
Our estimates are free, they’re written, and they’re line-item, so you know exactly what the re-sheet costs and what the shingles cost before anything starts. Call (866) 942-4187 to schedule yours.

FAQs – CertainTeed Roofing in Montclair
Do you install CertainTeed Landmark shingles on Montclair homes with original wood-shake roofs?
Yes, and it happens regularly. The sequence is the important part: we tear off the old wood shake, assess the skip sheathing underneath, and re-sheet the deck before installing the Landmark system. Skipping the re-sheet when the deck is rotted means the new shingles fail prematurely. Call (866) 942-4187 and we’ll walk you through what your specific home needs.
Why do CertainTeed shingles crack faster in Montclair than at the coast?
It’s the heat and UV. Coastal roofs get marine layer; Montclair roofs get 100°F days, low humidity, and intense sun on south- and west-facing slopes. That dries out the asphalt in Landmark shingles, which leads to cracking and granule loss after 15-20 years, even when the north slope looks fine. Repairing just the affected slopes can buy years before a full replacement. Call (866) 942-4187 for an inspection and honest assessment.
Can you replace just the underlayment under my CertainTeed Presidio tile roof?
Yes. The concrete tile usually has plenty of life left; the underlayment beneath it is what fails. We lift the tile, replace the underlayment, and reset the tile. It’s less expensive than a full tile replacement and it stops leaks at the valleys and flashings. Estimates are free at (866) 942-4187.
What should I expect when you tear off my old roof near Holt and Ramona?
Expect a decking assessment before any new CertainTeed product goes on. If your home was built in the 1950s or 1960s with wood shake over skip sheathing, there’s a strong chance we’ll need to re-sheet part or all of the deck. We’ll tell you during the estimate, not after the dumpster arrives.
Do you use CertainTeed underlayment on flat patio additions in Montclair?
We use Flintlastic SA where it’s specified for the slope, but we always confirm the termination details. In Montclair’s summer heat, a missed cap sheet or poor termination leads to wrinkles and pulls. Getting the right product on a flat patio addition is a different job than a pitched shingle roof. Call (866) 942-4187 to have us look at what’s on yours.
