CertainTeed Roofing in Pomona, CA | Gable Roof Repair
We provide independent CertainTeed roofing service across Pomona and CertainTeed service in Claremont, from shingle replacement to full re-roofs on the city’s older tract and bungalow stock. What separates our CertainTeed work here is that we diagnose from the deck up – Pomona’s pre-1960s homes carry original wood sheathing and underlayments that coastal roofers never see, and that changes the repair-vs-replace call every time. Call (866) 650-8319 for a straight answer and a free estimate.
Why Pomona Residents Choose Us for CertainTeed Service
We’ve spent years pulling apart CertainTeed roofs across Pomona – Landmark architectural shingles on mid-century tracts, Presidential Shake on larger homes, XT 25 three-tabs still holding on from decades past, and DiamondDeck or RoofRunner underlayment beneath the city’s aging tile. That mix shows up on nearly every street from the 91766 corridor over to the 91768 and 91769 ZIPs, and we’ve learned what fails first in each assembly. Neil Drummond, our owner, grew up in Irvine and trained in construction technology at Saddleback College, and he’s spent close to three decades reading roofs the way a mechanic reads an engine. The roof doesn’t lie – the materials tell you exactly what went wrong and when. That’s the lens we bring to every CertainTeed inspection and repair in Pomona.
We’re an independent contractor, not a manufacturer-authorized dealer. That matters, because our recommendation isn’t tied to moving a particular product line. It’s tied to what’s actually under the shingle. Visit our CertainTeed sales & service page to see how we approach the brand across all our service areas.

Common CertainTeed Roofing Problems We Solve in Pomona
CertainTeed materials are solid, but every roof fails the way its local climate tells it to. In Pomona, that means heat and wind – not rain – do most of the damage.
- Santa Ana wind shear on seal strips and ridge caps. Dry gusts funneling off the Cajon Pass hit east-side tract slopes hard, and the seal strips on older CertainTeed architectural shingles can’t hold once they’ve baked brittle. We see missing ridge caps and lifted shingles after nearly every fall wind event.
- UV-baked adhesive failure on older three-tab and early architectural shingles. Years of Inland Empire sun turn the sealant to powder. When the next wind comes, whole slopes lift at once. This is a Pomona-specific failure mode that coastal LA roofers rarely encounter to this degree.
- Underlayment failure beneath clay and concrete tile. The felt under original tile bakes to dust over decades while the tile itself still looks fine from the street. Water reaches the deck long before anything shows at the surface. This is one of the most common leak sources we trace on Pomona’s older homes.
- Fastener back-out and lifted flashing at valleys, vents, and chimney boots. Thermal cycling plus wind works nails loose and breaks the seal around penetrations. We find this on CertainTeed assemblies in every Pomona neighborhood, but especially on the 1950s and 60s tract stock.
- Wind-lifted shingles on one slope only. We frequently repair a single damaged plane rather than quoting a full replacement. That’s the repair-first approach our company name signals, and it’s how we’ve always worked in Pomona.
CertainTeed Service in Pomona: What Local Conditions Mean for Your Roof
Here’s what sets Pomona apart from every neighboring city we work, including CertainTeed in Covina: the housing stock itself. The pre-1960s tracts and bungalows near the old downtown and along the Cal Poly Pomona corridor still carry original wood sheathing and older underlayments. A CertainTeed re-roof on these homes often starts with probing the deck, not the shingle. On a coastal plywood deck, you strip the old roof, check for rot, lay new underlayment, and go. On a Pomona home from the Eisenhower era, the sheathing may be gapped, cupped, or delaminating at the edges. If we lay new CertainTeed Landmark shingles over a deck that’s already failing, we’ve just guaranteed a premature failure. So we check the deck first. It’s a step roofers who’ve only worked newer coastal builds rarely think to take, and it’s the reason a CertainTeed quote from one company can be thousands less than the honest number. We’d rather tell you the truth up front than surprise you after the tear-off. That’s our standard for every CertainTeed job in Pomona.
CertainTeed Models & Products We Service in Pomona
We work on the full CertainTeed residential range found across Pomona. Landmark architectural shingles dominate the mid-century tract stock. Presidential Shake and Presidential TL appear on larger custom homes in the 91766 area. XT 25 three-tabs remain on older rental properties and smaller bungalows. Beneath the tile roofs, we replace DiamondDeck and RoofRunner underlayments when the original felt has baked out. We use genuine CertainTeed shingles, ridge caps, and underlayment when the assembly calls for them. For flashing, boots, and valley metal, we’ll spec quality aftermarket components where the OEM format no longer makes sense on a repair. Parts are ordered to match your roof’s exact product line, so turnaround stays tight across Pomona ZIPs 91766, 91767, 91768, and 91769.

FAQs – CertainTeed Roofing in Pomona
Usually a repair. If the seal strips failed on wind-lifted shingles but the shingles themselves aren’t cracked or torn, we can re-seal or replace the affected section and reset the ridge caps. The re-roof call only comes when the deck is rotted or the shingles are too brittle to re-seal. Call (866) 650-8319 and we’ll get on the roof to tell you which situation you have.
That’s exactly what it usually is on Pomona’s older homes. Original felt underlayment bakes out over 40 or 50 years while the tile still looks sound. We replace the underlayment, reset the tile, and the leak stops. Call (866) 650-8319 for an inspection if you’re seeing water stains inside.
One slope is repairable in most cases. We match the existing CertainTeed product line, tear the damaged plane to the deck, re-nail if needed, lay new underlayment, and shingle it fresh. We don’t quote a full roof unless the deck or the rest of the shingles demand it.
We almost never recommend it. On Pomona’s pre-1960s homes, the sheathing underneath is usually the problem area, and covering over old shingles hides deck rot and adds weight the framing was never designed for. A proper tear-off lets us inspect what’s underneath. That’s the only way we’ll stand behind the work.
Landmark architectural shingles hold up well under the Inland Empire sun and carry a strong wind rating, but the real answer depends on your roof’s pitch and exposure. East-facing slopes take the brunt of Santa Ana gusts, so we look at the whole house before recommending a line. Call (866) 650-8319 for an assessment based on your actual roof.
