CertainTeed Roofing in Pomona, CA | Oakmont Roof Repair
We provide CertainTeed sales & service across Pomona, from downtown bungalows to the ranch tracts of the 91766 and 91768 ZIPs. The one thing that separates our CertainTeed work here is simple: we know how these shingles, tiles, and low-slope membranes actually fail under Pomona’s triple-digit sun and Santa Ana winds because we’ve repaired them on this city’s specific housing stock for years. If you need CertainTeed shingle replacement, tile underlayment work, or flashing repair, call Oakmont Roof Repair at (866) 942-0875 for a free estimate.
Why Pomona Residents Choose Us for CertainTeed Service
We’re roofing specialists, not a general contractor that happens to offer roofing. Every service call we run is built around one trade, and a good portion of our work in Pomona involves CertainTeed products because so many of this city’s homes were either originally roofed with CertainTeed shingles or had them installed during a re-roof at some point over the last three decades.
Noel Fierro, our owner, spent years on rooftops across San Bernardino County before Oakmont Roof Repair existed. He learned construction fundamentals at Victor Valley College, then put in time on every roof type the inland valley throws at a house: baked-out composition shingle, tile over failed felt, shake that’s dried past the point of repair. That background matters here because Pomona’s housing stock demands a roofer who can read three generations of roofing on a single block.
We carry seven major roofing brands including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That breadth means we spec what your roof actually needs, not what a manufacturer incentive program tells us to push. And when we service CertainTeed systems, we use genuine CertainTeed materials where matching matters.

Common CertainTeed Roofing Problems We Solve in Pomona
- Granule loss and brittleness on Landmark architectural shingles. Pomona’s west- and south-facing roof planes take the full force of the inland sun with almost no marine layer to soften it. CertainTeed Landmark shingles on these exposures bake dry, lose granules early, and turn brittle. A 20-year architectural shingle reading worn out at 12 years on a valley-facing slope is something we see regularly here, not occasionally.
- Santa Ana uplift on Presidential Shake edges and ridge lines. The Presidential Shake and Presidential Solaris lines are heavy laminates, but their exposed tab edges and ridge caps catch wind like a sail. Santa Ana events through the Pomona Valley dry out the sealed tab strip through repeated thermal cycling, then lift and crack the edges. The damage is usually isolated to gable ends and ridges rather than the whole field.
- Underlayment failure beneath sound tile. This is the single most common “roof looks fine but leaks” diagnosis in Pomona. On CertainTeed-spec clay and concrete tile installations, the tile field outlives the felt or synthetic beneath it by decades. We lift a visibly intact tile and find disintegrated underlayment underneath more often than we find a broken tile.
- Flintlastic membrane cracking at porch and patio tie-ins. CertainTeed’s Flintlastic low-slope membranes handle Pomona’s heat well for years, then fail at the terminations and flashings first. The thermal movement against stucco-on-wood-frame walls, plus relentless UV, pulls the membrane at the edges until it cracks and separates.
- XT 25 three-tab shingle failure on older re-roofs. Many Pomona tract homes from the 1960s and 1970s still carry XT 25 three-tab strip shingles, or did until recently. These shingles are thinner than architectural lines and Pomona’s heat plus Santa Ana grit scours them bare to the mat on the south slope while the north slope still looks serviceable. That uneven wear is a Pomona signature.
CertainTeed Service in Pomona: What Local Conditions Mean for Your Equipment
Here’s the thing about Pomona that you won’t find on a generic roofing page. This city’s original clay and concrete tile fields routinely outlive the felt beneath them. The tile will look fine for fifty years while the underlayment underneath has turned into dust. So the highest-value CertainTeed job in Pomona is often a tile lift-and-relay over new underlayment rather than a full new roof surface. We did exactly that on a Spanish-revival stucco house near the Pomona College side. The homeowner called about a ceiling stain that only appeared after winter rain. We lifted a run of barrel tile and found bare, disintegrated felt under a perfectly sound tile field. We replaced the underlayment across that plane, rebuilt the stucco-to-roof flashing and step flashing at the wall, set the original tile back, and the stain didn’t return the following season. Across the same block sits a postwar ranch we re-roofed with CertainTeed Landmark architectural shingles after the original XT 25 strip on the south slope had gone brittle and bare. Two opposite problems on the same street. Being fluent in both is what Pomona actually asks for.
CertainTeed Models & Products We Service in Pomona
We service the full CertainTeed residential roofing lines: Landmark architectural shingles including Landmark Pro and Landmark Solaris, XT 25 and XT 30 three-tab strip shingles common on older tract re-roofs, Presidential Shake and Presidential Solaris luxury shake-look shingles, CertainTeed tile underlayments, and Flintlastic low-slope membranes and patch products for porch and patio tie-ins. When we need to match an existing CertainTeed system or honor a manufacturer bundle, we use genuine CertainTeed shingles, underlayments, and membranes. Where the brand adds nothing to performance, like flashing, pipe boots, or some underlayment applications, we use quality aftermarket materials. That’s an honest parts philosophy for Pomona’s climate, not a brand purity exercise.

AfterCertainTeed Service Pricing in Pomona
CertainTeed in La Verne and Pomona varies by job type. Tile underlayment replacement on a valley-facing plane typically runs higher than isolated flashing work because it’s labor-intensive: lift the tile, strip the old felt, install new underlayment, relay the tile. Shingle replacement on damaged sections costs less than full re-roofs, but the price shifts depending on which CertainTeed product line you’re matching. Here’s what we typically see:
- Flashing repair (stucco-to-roof transition, step flashing, pipe boot replacement): $350 – $800 depending on access and how much stucco edge work is involved.
- Shingle replacement on a damaged section (Landmark or XT match, under 200 sq ft): $800 – $1,900 including tear-off of the damaged section and new underlayment.
- Tile lift-and-relay over new underlayment (one roof plane, including flashing rebuild at walls): $2,800 – $5,500 depending on pitch, tile type, and plane size.
- Full CertainTeed Landmark re-roof on a typical Pomona ranch or bungalow: $9,500 – $16,000 depending on decking condition and tear-off layers.

FAQs – CertainTeed Roofing in Pomona
Probably not. In Pomona, the underlayment beneath the tile usually fails decades before the tile itself does. The dry valley heat bakes the felt until it disintegrates, then winter rain finds the gaps. The fix is typically a tile lift-and-relay over new underlayment, not a new tile roof. Call (866) 942-0875 and we’ll confirm on-site.
Plan on 12 to 16 years on a west- or south-facing plane in Pomona, even though the manufacturer rates Landmark as a longer-lived product. Inland valley heat with triple-digit summers and almost no marine layer accelerates granule loss and brittleness. North- and east-facing slopes will last longer. We see the two-sided split constantly on Pomona homes.
Yes. We keep common CertainTeed colors stocked locally for Pomona turnaround, and we can order exact matches for Landmark and XT 25 lines when the color and weathering pattern call for it. The match won’t always be invisible if the existing shingles have years of sun exposure, but we’ll tell you that upfront before you spend anything.
First, document the damage with photos, then call us for an assessment. Santa Ana wind events in Pomona typically damage Presidential Shake edges, ridge caps, and gable-end laminates first. The fix is often isolated shingle replacement and sealant work, not a full re-roof. Call (866) 942-0875 for a free estimate.
Not always. If the shake is still sound and the decking beneath is intact, you may be able to overlay or repair. But Pomona’s dry heat bakes original wood shake until it’s brittle and split, and by the time you see gaps, the decking may have been exposed. We’ll give you an honest read either way. The roof doesn’t lie, and neither do we.
