Call (855) 382-3237 for a straight answer about your Owens Corning roof and what it actually needs.
Why Pomona Residents Choose Us for Owens Corning Service
Pomona homeowners get a lot of roofing pitches. Most are vague, and too many come from general contractors who handle roofing as a side line. We don’t work that way. We’re a roofing-only company, and we’ve spent years on Pomona roofs across Owens Corning sales & service, watching how Oakridge, Duration, and Supreme lines hold up under this city’s specific conditions. As an independent contractor, we’re not tied to any manufacturer quota. We choose Owens Corning products when they’re the right material for the roof in front of us. Brent Calloway, our owner, grew up in Costa Mesa and learned roofing through Orange Coast College’s construction technology program, where the instructors didn’t tolerate shortcuts. That same no-shortcuts standard applies to every Owens Corning roof we touch in Pomona, whether it’s a shingle repair on a 1960s ranch or a full replacement on a downtown bungalow.

Common Owens Corning Roofing Problems We Solve in Pomona
These are the failures we see most often on Owens Corning roofs in this area, tied directly to how Pomona’s climate works on aging shingle systems:
- Granule loss and asphalt exposure on older Oakridge and Supreme three-tab roofs. Pomona’s inland sun does not let up. After years of dry summer heat and direct UV, the granule layer wears thin, then the asphalt mat underneath starts going brittle. We see this constantly on original Owens Corning roofs from the 1980s and 1990s across north Pomona and the 91768 tract corridors.
- Wind-creased and peeled-back shingles after Santa Ana events. When the sealant strips bake out over time, a strong wind gust gets under the shingle edge and folds it back. This shows up most on 1950s-70s ranch homes in east Pomona where the roof pitch is moderate and the shingles have been cooking for decades. Ridge caps lift too, especially where the original nails have backed out.
- Dried, cracked WeatherGuard underlayment that fails at flashings. The first heavy rain after a dry spell is brutal on old Owens Corning underlayment. We get calls after summer monsoon downpours where water tracked through a cracked valley flashing or a dried-out vent boot seal, and the underlayment underneath had nothing left to stop it.
- Nail pops and loose fasteners on second-layer installs over skip sheathing. On downtown Pomona bungalows in 91766 and 91767, it’s common to find a second layer of Owens Corning shingles nailed over original skip sheathing. The nails don’t always bite into solid wood, so they work loose. Shingle seams open up, and water follows.
- Shingle blistering and thermal cracking on low-slope sections. Flat and low-slope additions on older Pomona homes trap heat differently than the main roof plane. Owens Corning shingles on those sections degrade faster, and the cracks that form around the blisters are exactly where the next leak starts.
Owens Corning Service in Pomona: What Local Conditions Mean for Your Equipment
Here’s what a generic Owens Corning page won’t tell you, and it matters if you own a home within our Pomona service area. The older bungalows and craftsman homes clustered around downtown and Lincoln Park, mostly in 91766 and 91767, were built when skip sheathing was standard practice. Roofers nailed shingles directly to boards spaced apart, not to a solid plywood deck. Over decades, Pomona homeowners added layers: first a reroof over the original Owens Corning shingles, then sometimes a third. What sits on those roofs now is often multiple layers of dried three-tab over skip sheathing that has curled, warped, or pulled away from the rafters. When we strip an Owens Corning roof on one of these homes, the deck underneath is almost never ready for new shingles. A homeowner calls it a reroof. The reality is a redeck. That’s the difference between a roof that sits true and one that fails again in three years. On a 1920s bungalow off Lincoln Park, our crew pulled three layers of dried Owens Corning three-tab off the front slope and found curled skip sheathing and gaps that had been hiding under the shingles for decades. We replaced the bad boards, re-nailed the deck flat, and laid new Oakridge architectural shingles with fresh WeatherGuard underlayment and new flashings at the porch roofline. The homeowner got a roof that finally sits true instead of a fourth layer trapping old moisture.
Owens Corning Models & Products We Service in Pomona
We install and repair the Owens Corning product lines most common on Pomona homes. That includes Oakridge architectural shingles, Duration architectural shingles, and Supreme and Supreme HR asphalt shingles. We also work with Owens Corning WeatherGuard underlayment, ridge cap, and starter shingle systems. On repairs, we match the shingle to the same product family and profile already on the roof whenever the deck and exposure are sound. For underlayment, flashing, and vent boots, we select quality aftermarket materials where they outperform what’s left of the original system. No fake “OEM or nothing” rigidity. No cheap substitutes that won’t last. Just the right material for the job. We stock common Owens Corning shingle colors and accessory materials for faster turnaround across Pomona, so you’re not waiting on a supplier order when the repair is straightforward.

AfterOwens Corning Service Pricing in Pomona
Roofing prices in Pomona shift with the scope of the job, the roof pitch, and what we find once the old layer comes off. A focused repair like replacing wind-creased shingles or resealing a flashing runs on the lower end. A full tear-off and Owens Corning replacement with redeck on a downtown bungalow runs higher, because the deck work is real labor and material. What we never do is hand you a vague number and then change it mid-job. Your estimate is broken down line by line, and if we find hidden deck damage during the job, we show you exactly what we found before any additional work starts. Call (855) 382-3237 for a free estimate on your Owens Corning roof in Pomona. We’ll inspect it, tell you straight what it needs, and give you a written number.

FAQs – Owens Corning Roofing in Pomona
On most Pomona homes, no. Many roofs here already carry a second layer, and Pomona’s building code limits roof layering in most cases. On downtown bungalows in 91766 and 91767, the existing layers typically sit on skip sheathing that needs replacement anyway. The right move is a full tear-off so we can see the deck and fasten new Owens Corning shingles to something solid. Call (855) 382-3237 and we’ll confirm what your roof actually has before quoting anything.
Santa Ana winds peel shingles when the sealant strip has baked out after years of Pomona sun and the nail pattern no longer holds the shingle flat. Older Owens Corning roofs on 1960s tract homes are especially prone because the original sealant degrades with heat and age. Once the shingle folds back, the nail holes tear open and water gets in. This is a repair we handle routinely in Pomona’s wind season.
Look at where the water shows up inside. Leaks near the chimney, vent pipes, valleys, or where a roof plane meets a wall usually point to flashing failure. Leaks that appear across a broad ceiling area during heavy rain typically point to shingle failure or worn underlayment. On Pomona roofs with cracked WeatherGuard and dried-out sealant, both often happen at once. We’ll find it during a roof inspection and show you photos of what we see.
Usually yes. We match Owens Corning shingles to the same product family, profile, and color already on the roof. Exact color matching gets harder on older roofs where the existing shingles have faded from Pomona sun exposure, but we’ll get as close as the manufacturer’s current palette allows and tell you up front if the match will be visible.
Owens Corning builds solid products, and their architectural lines handle inland heat well when installed correctly over a sound deck. The real variable in Pomona is the deck underneath and the quality of the install. A premium Owens Corning shingle nailed over failed skip sheathing won’t outlast a mid-tier shingle installed over a solid, flat deck. We’ll give you a straight recommendation based on your specific roof, and if Owens Corning is the right call, we’ll tell you exactly which line fits your budget and your exposure. Call (855) 382-3237 for an exact quote on your specific roof.
