Owens Corning Construction in Pomona, CA | San Mateo Construction
We’re San Mateo Construction, an independent Owens Corning roofing service provider handling full replacements, repairs, and storm damage work across Pomona. The one thing that makes our Owens Corning work here different: we know the 1920s – 1950s citrus-era bungalows and the specific ways their old decking and framing fail under San Gabriel Valley heat before a single shingle goes down. Call (855) 901-7266 for a free estimate.
Why Pomona Residents Choose Us for Owens Corning Service
We’ve torn off enough roofs in Pomona’s 91766, 91767, 91769, and 91797 ZIPs to know what’s underneath them. A lot of general contractors can order Owens Corning shingles from a supply house. Fewer can tell you that the original 1x board decking on a 1940s bungalow off West Holt Avenue won’t hold a roofing nail the way modern plywood or OSB will, and that skipping the re-deck is exactly how you get nail pops and premature lift within five years.
Noel Carrington, our owner, started learning the trade helping his father pour concrete footings in San Mateo, and he’s carried that foundation-first mindset into every roof we touch, including Owens Corning service in Claremont. We stock genuine Owens Corning shingles, WeatherLock underlayment, and ProEdge hip and ridge locally for faster turnaround on Pomona jobs. We’re not an authorized Owens Corning dealer, and we don’t pretend to be. What we are is a licensed general contractor who describes the work honestly, uses the product as the manufacturer specifies, and stands behind the install.

Common Owens Corning Construction Problems We Solve in Pomona
These are the roofing failure modes we see most often on Owens Corning roofs in Pomona. Each one ties to a specific local condition, not just normal wear.
- Thermal cracking and granule loss on south- and west-facing slopes. Pomona routinely pushes over 100°F in the summer, and older Oakridge installations take the worst of it. We see shingles crack and shed granules where the afternoon sun hits hardest, especially on unvented or minimally vented attic spaces from the 1950s tract stock.
- Wind uplift and tab lifting after Santa Ana events. Shingles installed during cool coastal mornings often never fully activate their sealant strips. When the Santa Anas blow through the foothill corridors, those unsealed tabs lift along rake edges and ridges, and water gets under them. We run this check on nearly every Pomona repair call after a wind event.
- Premature failure at valleys and penetrations over old decking. The citrus-era bungalows near downtown Pomona often have skip sheathing or original 1x boards that were never upgraded before the last reroof. Those surfaces don’t hold nails like they should, and signs of it show up first at the valleys, pipe boots, and vents.
- Algae streaking on north slopes. North-facing roof planes in Pomona stay shaded and damp longer than the south-facing ones, and the 1990s-era Owens Corning installs around the 91766 and 91767 areas often show dark streaking. It’s cosmetic in most cases, but worth addressing during a full replacement with algae-resistant lines.
- Unpermitted roof-over work. Pomona has dense pre-1940 housing with tight lot lines, and we frequently find a second layer of shingles installed over the original without a permit or proper deck inspection. That old layer masks the real condition of the decking and framing, and it changes how we approach the tear-off.
Owens Corning Service in Pomona: What Local Conditions Mean for Your Equipment
Pomona’s pre-1940 housing stock and tight lot lines mean many re-roofs here start with as-built verification and permit research at the city building department, before any Owens Corning shingle is ordered. That’s not a generic step we’d do in any city. It’s specific to Pomona because so many of these citrus-era lots had owner-builder additions, enclosed porches, and roof-over work done across decades, some of it never pulled a permit. We’ve seen shared foundations between neighboring bungalows on older blocks and framing that was never upgraded to code. When we pull a roof on a 1920s craftsman in the 91767 ZIP, we’re not guessing at what the decking looks like. We check the city’s records, verify the as-built against what’s actually there, and only then spec the Owens Corning system, whether that’s Duration over new plywood decking or a repair on an existing install. That first step has saved Pomona homeowners from ordering materials for a roof that couldn’t legally or safely be installed as planned.
Owens Corning Models & Products We Service in Pomona
We install and repair the full Owens Corning residential roofing line here: Oakridge, Duration, Duration FLEX, and Supreme, and we also provide Los Serranos Owens Corning service. Each has a different profile and price point, and we’ll help you choose based on your roof’s pitch, the amount of direct sun the house gets, and whether you’re dealing with a 900-square-foot bungalow or a larger mid-century tract home.
On repairs, we match the existing shingle line whenever possible. On full replacements, we use genuine Owens Corning shingles and accessories, WeatherLock underlayment and ProEdge hip and ridge, because mixing aftermarket components can void warranty coverage. If a Pomona roof is over 20 years old with multiple failure points, we’ll usually recommend full replacement over spot repairs. It’s the honest call more often than not.
We arrived at that position the hard way. On a 1940s bungalow off West Holt Avenue in the 91767 ZIP, we pulled the original wood shake and found skip sheathing over 2×4 purlins that had never been upgraded. The homeowner had been chasing leaks for two seasons. We re-decked with plywood before installing Duration shingles in a cool-roof color to meet Title 24, and the ridge vent upgrade dropped attic temperatures noticeably. Two seasons of patchwork would never have solved what was wrong underneath.

AfterOwens Corning Service Pricing in Pomona
What you’ll pay for Owens Corning work in Pomona depends mostly on the roof’s size, the existing decking condition, and whether we’re repairing or replacing. Here are the line-item ranges we quote for most Pomona homes:
| Service | Price Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
A full tear-off on a 1,200-square-foot Pomona bungalow with re-decking and Duration shingles will land closer to the middle or upper end of that replacement range. A straightforward repair on a newer roof, like resealing lifted tabs or replacing a section of ridge, stays near the bottom of the repair range. Call (855) 901-7266 for a free estimate. We’ll walk the roof, check the decking, and give you a written line-item quote.

FAQs – Owens Corning Construction in Pomona
Yes, Duration shingles are built with a heavier mat and a more impact-resistant asphalt formulation than standard Oakridge, which helps them resist thermal cracking under repeated 100°F+ heat exposure. For Pomona’s hot inland climate, we steer most homeowners toward Duration or Duration FLEX on south- and west-facing roof planes. Call (855) 901-7266 for a specific recommendation on your home.
Yes, Pomona requires a building permit for a full reroof, and yes, Owens Corning’s warranty coverage assumes the roof was installed to code, which includes the permit and inspection. We handle the permit paperwork as part of our scope, and we’ve found that permit research on Pomona’s older bungalows often surfaces unpermitted prior work that changes the job, which is exactly why we start there.
No, and we won’t install over it. Skip sheathing from the citrus era doesn’t provide a solid nailing surface, and Owens Corning’s installation specs call for solid decking. The right fix is to re-deck with plywood or OSB before shingles go down, which we did on the West Holt Avenue bungalow and would recommend for any Pomona home with that condition. Call (855) 901-7266 and we’ll inspect your decking before you buy a single shingle.
Owens Corning Duration shingles include algae resistance, and the Supreme line also carries algae-resistant protection. On Pomona homes with existing 1990s-era staining, a full replacement with a current algae-resistant line is usually the cleanest fix; a roof wash can improve the appearance short-term but won’t stop the staining from returning. Call (855) 901-7266 for a straight answer on whether your roof needs a wash or a replacement.
Most 1,200-square-foot Pomona homes land between $12,000 and $18,000 for a full tear-off with re-decking and Duration shingles, depending on the existing decking condition, roof pitch, and whether the home needs Title 24 cool-roof upgrades. That includes the underlayment, ridge vent, and matching hip and ridge caps. Call (855) 901-7266 for an exact quote after we inspect the roof.
