CertainTeed Construction in Pomona, CA | Timberline Contractors
We provide independent CertainTeed roofing service across Pomona and CertainTeed repair in Montclair, from re-roofs on century-old bungalows to full Landmark replacements on post-war tract homes. The thing that separates our CertainTeed work here is the pre-roof inspection of what’s underneath: Pomona’s raised pier-and-beam foundations settle, and a shingle system is only as good as the deck it’s fastened to. Call (866) 253-5808 for a free estimate from a contractor who knows both the product line and what Pomona’s older framing does to it.
Why Pomona Residents Choose Us for CertainTeed Service
We specify CertainTeed Landmark architectural shingles, Presidio metal, and the accessory flashing and underlayment that make a system hold up in this specific climate. We’re an independent contractor, not authorized or sponsored by CertainTeed, which means every recommendation is driven by what your roof deck, pitch, and sun exposure actually require. Nelson Fung, our owner and general contractor, learned the trade at Los Angeles Trade-Technical College and spent years on Eastside bungalow remodels before running Timberline Contractors. He’ll tell you straight when a cheaper accessory SKU will cost you twice in three years. Our team works across Pomona service area ZIP codes 91766, 91768, 91769, and 91797, and we keep CertainTeed-branded starter, ridge, and flashing on hand for faster turnaround.

Common CertainTeed Construction Problems We Solve in Pomona
- Seal strips baking on south and west slopes. Pomona’s summer heat and Santa Ana wind events lift Landmark shingle tabs before their rated life. We see granule loss concentrated on the sun-facing planes of homes near Lincoln Park and the 10 corridor, and we re-spec starter and ridge details to handle the wind uplift.
- Wavy skip sheathing on pre-war bungalows. The 1900s-1940s wood-frame stock in Pomona’s older neighborhoods often has original skip sheathing over pier-and-beam framing. Decades of dry-summer/wet-winter cycling cupped those boards. A CertainTeed overlay on that deck telegraphs every seam and pops fasteners within a few seasons.
- Flashing failures at porch roofs and chimneys. Winter rains hit aged flashing hard on Pomona’s Spanish Colonial homes, especially where a prior contractor mixed brands or added vents during a kitchen remodel or ADU conversion. Wind-driven rain gets behind the underlayment and shows up as ceiling stains months later.
- Stucco cracking at rake and fascia edges. Thermal cycling dries out the stucco where the CertainTeed roof plane meets the wall. In Pomona’s hot, dry stretches followed by heavy winter rain, those cracks become pathways for water intrusion along the eaves.
- Re-roofs on settled foundations. Before we lay any CertainTeed system on a Pomona bungalow, we check the piers. A roof on a moving house will tear underlayment and break seal strips no matter how good the shingle is.
CertainTeed Service in Pomona: What Local Conditions Mean for Your Equipment
Here’s the thing about Pomona that a generic CertainTeed page will never tell you: the older bungalow and Spanish Colonial stock near downtown and Lincoln Park sits on raised pier-and-beam foundations with lath-and-plaster walls. Those piers settled and, in some cases, rotted over decades of dry-summer/wet-winter cycling in the expansive clay soils across the valley floor. So before we lay a CertainTeed roof system on a 1920s craftsman near Lincoln Park, we routinely re-level the structure and repair or replace piers. A re-roof on a moving house, even with OEM CertainTeed underlayment and Landmark shingles, will fail at the seams. This is not a problem a newer slab-on-grade tract city two miles east ever triggers. In Pomona, the foundation work comes first, then the roof.
CertainTeed Models & Products We Service in Pomona
We install and repair the CertainTeed lines that make sense for Pomona’s housing stock: Landmark architectural shingles for their wind ratings on exposed slopes, Presidio synthetic slate and metal roofing for Spanish Colonial and upscale replacements, XT25 and RoofRunner underlayment for deck protection, and Cedar Impressions siding where we’re tying the roof plane into exterior walls. On any re-roof, we use CertainTeed-branded underlayment, starter, ridge, and flashing where the warranty system calls for it, and we spec equivalent-quality accessories elsewhere on the deck rather than chasing the cheapest SKU. If the sheathing or flashing underneath is failing, we’ll tell you to fix that first instead of selling a shingle-only patch that buys you two seasons.

FAQs – CertainTeed Construction in Pomona
Yes, and it’s the first thing we check. If the piers have settled, the roof deck moves with the framing, and no shingle system will hold its seal. We re-level before we roof. Call (866) 253-5808 for an inspection that covers the foundation, not just the shingles.
No. Wavy, cupped skip sheathing telegraphs through the shingles and pops fasteners. We add plywood sheathing over the original boards after re-leveling, then install CertainTeed underlayment and Landmark on a flat deck. That’s the only way the wind warranty actually means something in Pomona. Call (866) 253-5808 to have your deck evaluated.
We do. Pomona’s warehouse and industrial conversions along the 10 and 60 corridors, plus the ADU and garage conversion work we build, all get the same CertainTeed system and flashing detail as our residential re-roofs, and we offer matching CertainTeed service in Claremont. Call (866) 253-5808 to talk through your project scope.
Most Pomona roof replacements land between $8,000 and $20,000, with metal CertainTeed Presidio systems starting higher. If we’re also re-leveling piers or adding plywood sheathing, that’s itemized separately. Call (866) 253-5808 for an exact quote, estimates are free.
