Owens Corning Construction in San Antonio Heights, CA | Elmwood Contractors
We provide independent Owens Corning roofing installation, repair, and storm-damage service across San Antonio Heights and the 91784 foothills as our General Contractor in San Antonio Heights. The one thing that sets our Owens Corning work apart here is county-level experience: every reroof in this unincorporated community goes through San Bernardino County permitting, not City of Upland, and we pull those permits correctly the first time. If you need Owens Corning shingles or underlayment installed, repaired, or inspected, call (866) 253-8554 for a free estimate.
Why San Antonio Heights Residents Choose Us for Owens Corning Service
Our crews work with Owens Corning materials on a strictly independent basis. We are not authorized, sponsored, or endorsed by Owens Corning, which means we recommend the right Owens Corning product for your roof rather than the one a manufacturer program tells us to push. Nolan Shepherd, who runs Elmwood Contractors, grew up in Fullerton’s Sunny Hills neighborhood watching 1960s tract homes develop the same failures we still diagnose today. He learned early which construction corners shouldn’t be cut. That’s the mindset we bring to every Owens Corning roof in San Antonio Heights.
We keep Owens Corning starter strips, ProArmor underlayment, and matching Duration and Oakridge profiles on hand for the foothill homes we serve. When a Santa Ana blow peels back a few tabs on a ridge, we can usually match the shingle and get the repair done without making you wait on a special order. We are a single-source general contractor, which means the same team that handles your Owens Corning roof can also manage the fascia, gutter, and flashing work that ties into it.

Common Owens Corning Construction Problems We Solve in San Antonio Heights
San Antonio Heights hits Owens Corning roofs harder than most flat-lot neighborhoods in the Inland Empire. Here are the failure modes we see and fix regularly:
- Wind-lift and seal-strip failure along ridges and gable edges. Santa Ana gusts funnel through the San Gabriel Mountain foothills and peel back Oakridge and Duration tabs that never fully sealed. The west-facing gable ends on steep lots get hit hardest. We reseal where the strip is still intact and replace the tabs where it isn’t.
- Granule loss and accelerated aging on south- and west-facing slopes. Inland summer UV tears through roofs up here. We regularly see Duration shingles shedding granules a decade early on the slopes that take direct afternoon sun, exposing the fiberglass mat before the rated life is anywhere close.
- Three-tab Supreme roofs failing on 1950s-70s custom homes. Many of the original mid-century houses in San Antonio Heights still carry their first or second Supreme layer. The flashing was rarely upgraded when the overlay went on, so wind-driven rain finds its way past the eave and into the fascia. By the time we see the water stain, the decking has usually been wet for a while.
- Underlayment failure on low-slope porch and addition roofs. Homes on pier-and-grade foundations move. When the decking shifts, ProArmor or felt underlayment tears at the seams. Add winter rain running off the foothill slopes and you get a porch roof that leaks even though the shingles look fine.
- Ridge and hip cap blow-through on steep slopes. The steeper the pitch, the more uplift at the ridge. Older nail patterns on Superior ridge caps were not designed for the wind speeds this corridor produces. We replace the cap and reseal the ridges with the correct Owens Corning accessory.
Owens Corning Service in San Antonio Heights: What Local Conditions Mean for Your Roof
San Antonio Heights is unincorporated San Bernardino County land. That single fact changes how every Owens Corning reroof here gets planned and permitted. A roofer out of Upland or Rancho Cucamonga who assumes city jurisdiction will grab the wrong forms and stall your job before it starts. We pull every roof through San Bernardino County directly. The county’s high-fire-severity foothill rules also push Class A fire-rated assemblies. Owens Corning Duration and Oakridge shingles can meet that Class A rating when paired with the right underlayment and decking, but the assembly must be documented and inspected to county standards. Brush-clearance detailing around the permit, access for fire inspection, and eave construction that resists ember intrusion all tie into the reroof plan. That’s a layer of preparation flat-lot roofers rarely think about. We plan for it on every estimate we write in 91784. For a broader look at how we serve the area, visit our San Antonio Heights service area page.
On a steep lot off the alluvial fan above Owens Corning in Upland, we tore off two layers of aging three-tab Supreme on a 1960s custom home whose west-facing slope had lost most of its granules and was lifting at the ridge after a Santa Ana blow. We redecked the worst section, set Owens Corning Duration shingles with ProArmor underlayment, upgraded the eave flashing, and pulled the reroof through San Bernardino County with a Class A assembly to match the foothill fire rules. The county inspector passed it without a correction notice. That’s how we like every Owens Corning job here to end.
Owens Corning Models & Products We Service in San Antonio Heights
We install, repair, and maintain the full Owens Corning roofing lineup that makes sense for Southern California foothill homes:
- Duration Series (TruDefinition Duration) Shingles – our most common recommendation for San Antonio Heights because the SureNail strip holds better on steep slopes during Santa Ana winds.
- Oakridge Architectural Shingles – a solid mid-tier option when the budget is tighter and the slope exposure is moderate.
- Supreme Three-Tab Shingles – mostly what we tear off on original 1950s-70s homes, though we still match them for partial repairs on structures where a full replacement isn’t in the cards yet.
- ProArmor Synthetic Underlayment – our standard underlayment on every reroof because it handles decking movement on pier-and-grade foundations better than felt.
The right material in the right place. Everything else is just catching up to that decision. We match the correct Owens Corning shingle profile and use Owens Corning-branded or equal-rated synthetic underlayment and starter strips rather than mismatched generics, so wind and ice-and-water warranty layers stay consistent across the whole roof.

FAQs – Owens Corning Construction in San Antonio Heights
Yes. San Antonio Heights is unincorporated, so every reroof requires San Bernardino County permits, not City of Upland permits. We handle the full permit package, including the fire-resistance documentation the county requires for high-severity foothill zones. Call (866) 253-8554 and we’ll confirm what your specific roof needs.
Yes, when installed correctly. Duration shingles have a reinforced nail strip that holds better than older three-tab designs during sustained gusts. The catch is that the starter strip and ridge cap must also be spec’d correctly for the slope and exposure. We install Duration with Owens Corning starter strips and cap accessories so the whole system works together.
A repair if the granule loss is isolated to one slope and the shingles still seat flat. A replacement if you see bare fiberglass mat on two or more planes or tabs lifting along the ridges. We’ll tell you straight which one applies. Call (866) 253-8554 and we’ll inspect before recommending anything.
Usually. We stock the most common Owens Corning Duration and Oakridge colors for San Antonio Heights roofs and can source exact matches for older Supreme three-tab profiles. If the shingle is discontinued, we’ll show you the closest available match before we start.
Steep slopes add staging time, safety equipment, and often require roof brackets and fall-protection setup that flat roofs don’t. It also affects drainage detailing: eave flashing, drip edges, and gutter placement have to account for water coming down fast from the San Gabriel foothills. We build that into every quote. Call (866) 253-8554 for a detailed estimate that reflects your actual roof pitch.
