Why Pomona Residents Choose Us for Owens Corning Service
Most roofing crews in Pomona see a failing roof and pull out a full-replacement quote before they’ve even inspected the underlayment. That’s not how we work. Noel Cardenas grew up in Muscoy watching his uncle patch flat roofs on rental properties, and he’s spent more than two decades working roofs across the Inland Empire. When he sends our crew to a Pomona home, the first question is never “what can we sell” but “what’s actually failing.” We inspect before we recommend. That’s how a 1940s Spanish Colonial Revival in Lincoln Park keeps its original tile, and how a 1950s tract home in 91767 gets only the shingle replacement it actually needs. Our Owens Corning sales & service knowledge runs deep because we’ve installed and repaired these products on hundreds of Pomona roofs, not because a manufacturer handed us a plaque.

Common Owens Corning Roofing Problems We Solve in Pomona
- Granule loss and curling on Duration® shingles. South- and west-facing slopes in Pomona get hammered by relentless summer sun. After 10 to 15 years, we often find Duration® shingles shedding granules and curling at the edges, especially on homes with minimal tree cover around Phillips Ranch and the 91766 neighborhoods.
- Wind-lifted shingle tabs from Santa Ana events. Santa Ana winds don’t just rattle fences here. On windward slopes and ridge lines, we regularly see Duration® and Oakridge® tabs lifted and creased, which cracks the seal strip and lets water work under the shingle. Loose or missing clay tiles are the same story on older Pomona homes.
- Blistering and splitting on Oakridge® in under-ventilated attics. Many 1950s tract homes in Pomona were built with the absolute minimum attic ventilation. Trapped heat accelerates asphalt aging from underneath, and we’ve pulled up Oakridge® shingles that looked fine from the street but were split through the mat.
- Hidden leaks from expired WeatherGuard® underlayment. Low-slope valleys and penetrations are where water lingers. During monsoon-season cloudbursts, we find WeatherGuard® underlayment that deteriorated far faster than expected because ponding water sat on it longer than the design ever anticipated.
- Crumbled felt under original clay tile. In Pomona’s Lincoln Park and downtown historic tracts, the clay tile on top often looks fine while the felt beneath it has turned to dust. The roof leaks even though every visible tile is still in place. This is the most common call we get from owners of 1920s and 1930s bungalows.
Owens Corning Service in Pomona: What Local Conditions Mean for Your Roof
Pomona has one of the highest concentrations of pre-war and mid-century homes in Southern California. Walk the streets around Lincoln Park, Wilton Heights, or the downtown tracts and you’ll see original mission-style clay tile and wood-shingle roofs that are now 70 to 100 years old. The tile itself is often salvageable. The hidden felt underlayment beneath it is not. Here’s what actually happens: the felt expires, monsoon rain gets through, and water follows the roof deck to the eaves, where dry rot sets in. The local fix we recommend is lifting and re-laying the existing tile over new Owens Corning WeatherGuard® underlayment rather than a full tear-off. It preserves the historic street appearance, keeps salvageable tile out of a landfill, and costs meaningfully less than a complete replacement. In Pomona specifically, the tile match matters because these homes sit on streets where visual consistency still shapes property values. We do this work routinely, and we do the eave dry-rot repair that goes with it because the two problems almost always arrive together.
We recently worked on a 1940s Spanish Colonial Revival in Lincoln Park with original clay tile. After a windstorm, several tiles were loose and we found the felt underlayment had crumbled to dust. We removed the tile carefully, replaced the underlayment with Owens Corning WeatherGuard®, re-laid the original tile, and repaired the dry rot at the eaves. From the street, the roof now looks untouched. That’s the standard we hold for every historic roof in Pomona and the Owens Corning service in Claremont area.
Owens Corning Models & Products We Service in Pomona
We work with the full Owens Corning residential lineup, including Owens Corning service in Walnut, that makes sense for Pomona’s housing stock. That includes Duration® series architectural shingles, Oakridge® architectural shingles, Supreme® three-tab shingles, and WeatherGuard® underlayment. For replacements, we use genuine Owens Corning shingles and underlayments so warranty eligibility stays intact. For flashing and vent components, we source quality aftermarket parts when they offer better corrosion resistance or longer service life than the OEM piece. We keep common Owens Corning colorways and underlayment rolls stocked for fast turnaround across Pomona, especially for partial repairs where matching the existing roof matters more than anything else.

AfterOwens Corning Service Pricing in Pomona
What you’ll pay depends on what’s actually wrong. A targeted repair using Owens Corning shingles might run a few hundred dollars. Replacing the underlayment on a Pomona tile roof and re-laying the original tile typically lands between $4,500 and $9,000 depending on the roof’s size, pitch, and how much dry-rot repair the eaves need. A full Duration® shingle replacement on a standard Pomona bungalow usually falls between $8,000 and $16,000. Every estimate we give is a written line-item quote, so you can see exactly where the money goes. No change orders. No vague allowances. Call (866) 361-0798 to schedule your free estimate.

FAQs – Owens Corning Roofing in Pomona
Yes, in most cases we can match the existing Owens Corning shingle color and line, provided the shingle is still in current production or a compatible shade is available. Pomona’s intense sun fades shingles over time, so we’ll pull a sample from your roof and match against current Owens Corning color boards before we order. Call (866) 361-0798 for an exact match assessment, which we include with every free estimate.
Pomona’s summers run long and hot, with south- and west-facing slopes absorbing direct sun for 10-plus hours a day. That UV load accelerates granule loss and asphalt oxidation. Owens Corning Duration® shingles are engineered with SureNail® technology and heavier mats than three-tab lines, which helps, but no shingle escapes the Inland Empire sun forever. We typically see Duration® on unprotected slopes hit the 15-year mark before granule loss becomes visible. Attic ventilation matters as much as the shingle itself. Call (866) 361-0798 for a roof inspection if your shingles are over a decade old.
Yes, and we’ve installed WeatherGuard® underlayment under original clay tile throughout Pomona’s historic districts and nearby Owens Corning in Covina. It is a synthetic underlayment with good tear strength and a slip-resistant surface, which matters when we’re re-laying heavy clay tile. For Pomona’s low-slope bungalow sections, we specify it because monsoon ponding punishes felt underlayment quickly. The felt originally installed under Pomona’s pre-war tile roofs was never designed to last 80 years. WeatherGuard® is our standard replacement.
A full Duration® shingle replacement on a typical Pomona home runs between $8,000 and $16,000 depending on roof size, pitch, tear-off layers, and deck repair. Homes in the 91766 and 91767 corridors with original wood shake or multiple shingle layers trend toward the higher end because of added tear-off and disposal labor. Call (866) 361-0798 for a written line-item quote on your specific roof, free of charge.
It depends on the slope. Asphalt shingles are rated for slopes of 2:12 or steeper. Some Pomona bungalows have porch roofs or rear sections flatter than that, and those sections need a different approach, typically a modified bitumen or a properly detailed underlayment system. We assess every slope during inspection and will not install shingles where they will fail. From the ridge cap down, the details dictate the material.
