Owens Corning Construction in Pomona, CA | Timberline Contractors
We provide independent Owens Corning roofing installation and repair across Pomona, from the century-old bungalow blocks near downtown to the 1960s and 70s tract homes south of the 10, plus Los Serranos Owens Corning service for nearby homeowners. What makes our Owens Corning work different here is that we start every re-roof by checking whether the deck is still level, because in this city a surprising number of roofs have been quietly pushed out of plane by settled pier-and-beam foundations underneath. Call (866) 253-5808 for a free estimate, and we’ll talk about what’s actually happening on your roof before we quote a single shingle.
Why Pomona Residents Choose Us for Owens Corning Service
We read Owens Corning’s published installation and ventilation specs on every job rather than leaning on a badge. That matters more than most homeowners realize. An Oakridge shingle performs differently on a 1920s Spanish Colonial with original skip sheathing than it does on a 1978 tract house with plywood decking, and Pomona has both, often on the same street. Nelson Fung, our owner and general contractor, learned the trade at Los Angeles Trade-Technical College and spent years swinging hammers across the LA basin before launching Timberline Contractors. He is the guy who will tell you which OC product actually belongs on your specific roof, not just what’s on the truck. We’re a full-scope Owens Corning sales & service contractor serving the entire Pomona service area, and we bring that materials-nerd energy to every estimate.

Common Owens Corning Construction Problems We Solve in Pomona
- Heat-tracking and tab seal failure on west and south slopes. Pomona’s summer sun pushes roof surface temperatures past 150°F on exposed slopes. Older OC three-tab and economy architectural shingles often lose their self-sealing adhesive bond in those conditions, leaving tabs that curl and catch wind. We see this most often on 1960s and 70s tract homes with limited attic ventilation.
- Wind uplift and missing-tab loss at hips and ridges during Santa Ana events. When the dry gusts come down from the mountains, a Prior installer who high-nailed above the nailing zone on Duration shingles left the tabs vulnerable. We inspect nail placement and re-secure or replace the affected courses before the next big wind event.
- Granule loss and shingle cracking over raised pier-and-beam bungalow stock near downtown. Seasonal clay-soil movement racks the roof structure on Pomona’s older homes, opening seams and valleys before the shingle itself is worn out. We find cracked shingles and bare spots on homes that are less than 15 years old, because the movement underneath has been working against the shingle the whole time.
- Early aging on low-slope porch and addition roofs. Owens Corning shingles are not designed for extremely low pitches, but plenty of Pomona porches and additions got them anyway. We see premature granule loss and water intrusion where a previous installer ignored OC’s minimum slope requirements.
- Under-ventilated attics cooking the shingles from below. Many older Pomona homes were built with minimal intake ventilation and no ridge vent. Heat builds up under the roof deck, accelerating shingle aging and driving up cooling bills. A proper OC assembly includes ventilation, not just shingles.
Owens Corning Service in Pomona: What Local Conditions Mean for Your Equipment
Pomona’s older bungalow blocks sit on raised pier-and-beam foundations rather than slabs, so a re-roof here can reveal a roof plane that’s out of level because the supports below settled. That’s the thing a slab-foundation city never forces us to do. On a 1920s Spanish Colonial bungalow near Lincoln Park, our crew pulled worn three-tab shingles and found the south slope furring and a couple of rafters had been quietly pushed out of plane by settled supports under the house. We sistered and shimmed the framing, re-nailed the deck, added ridge and intake ventilation the attic had never had, and finished with Owens Corning Duration shingles and matching OC ridge cap. The owner got a level, vented assembly that stands up to the summer heat instead of another patch that would fail in two seasons. That’s the difference between putting shingles on a roof and actually fixing a Pomona roof.
Owens Corning Models & Products We Service in Pomona
We install and repair the full Owens Corning architectural lineup: Oakridge shingles for solid mid-tier performance, Duration with SureNail Technology where wind resistance is the priority, Supreme tab shingles on older budget re-roofs, and the Berkshire Collection or Woodmoor designer shingles on custom and historic-core homes. We use genuine Owens Corning shingles and matching OC starter, ridge, and hip accessory components so the system and its warranty paperwork stay coherent. Where it makes sense, we specify quality aftermarket underlayment and ventilation that meet California code, because those components are not tied to the shingle warranty and better products exist. We tell owners honestly when a targeted repair, flashing, a valley, a section of field shingles, will buy real years versus when the deck or the whole assembly is at end of life.

AfterOwens Corning Service Pricing in Pomona
Roof work costs what it costs because of what we find once the old shingles come off. Pomona’s older homes add a layer of framing and leveling checks that don’t exist in newer tract cities, and that’s reflected in the estimate. Here’s what we quote across the Pomona market:
| Service | Pomona Price Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
| Tile Roof Repair | $600 – $2,500 |
| Metal Roof Installation | $15,000 – $40,000 |
Every estimate is free and written line-item. No change orders unless we find something genuinely hidden, and we’ll show you photos before we ask for a dime more. Call (866) 253-5808 to schedule a roof assessment.

FAQs – Owens Corning Construction in Pomona
Yes, and honestly, that’s exactly the kind of Pomona roof we’re built for. We check framing level and re-secure the deck before laying any Owens Corning shingle. We’ll sister and shim rafters where needed, re-nail the deck, and then install the shingle system on a stable plane. Call (866) 253-5808 and we’ll take a look at what’s shifting under your roof.
Almost always yes. Pomona’s summer sun—and conditions in neighboring communities where we provide Owens Corning service in Claremont—drives attic temperatures high enough to accelerate shingle aging and force your AC to work harder. We add ridge and intake ventilation when we re-roof, and we can retrofit ventilation on an otherwise sound OC roof. A ventilated attic keeps the shingles cooler and the house more comfortable.
We use Duration shingles with SureNail Technology on wind-exposed slopes, and we inspect nail placement on existing roofs for high-nailing above the nailing zone, which is the number one cause of tab loss in Santa Ana conditions. Hips and ridges get extra attention because that’s where wind uplift shows up first. Call (866) 253-5808 for a wind-worthiness inspection before the next big event.
It can, but the prep work matters. Irregular roof lines and original skip sheathing require careful deck preparation before a modern architectural shingle goes on. We’ve handled plenty of these near Lincoln Park and across the downtown core, as well as Owens Corning repair in Montclair, and we’ll spec the right OC product for the pitch and exposure. The goal is a shingle that looks right and stays put on Pomona’s older housing stock.
When the shingles are largely sound and the problem is isolated, like flashing around a chimney, a single valley, or a wind-damaged section. Pomona’s climate means we often see granule loss on south and west slopes while the rest of the roof is still healthy. We’ll tell you straight if a targeted repair will buy five or more years, and equally straight when the deck or the whole assembly is at end of life. Call (866) 253-5808 for an honest assessment.
