Owens Corning Roofing in Pomona, CA | Baycrest Roofing
We provide independent Upland Owens Corning service and roofing across Pomona, including shingle replacement, leak repair, and decking work. What separates our Owens Corning work here is straightforward: we inspect the deck and edge conditions first, because Pomona’s block-by-block housing stock means no two roofs age the same way. Baycrest Roofing is not manufacturer-affiliated or authorized by Owens Corning, so our recommendations follow the roof, not a brand program. Call (866) 412-5697 for a free estimate.
Why Pomona Residents Choose Us for Owens Corning Service
We carry Owens Corning alongside six other major shingle manufacturers: GAF, CertainTeed, IKO, Atlas, Tamko, and Boral. That matters because we’re not trying to force-fit a single product line onto your Pomona roof. If Owens Corning is the right material, we recommend it; if another brand matches your deck, slope, and exposure better, we’ll say so. You get seven brands and one honest answer.
Nolan Cafferty, our owner, grew up in Temecula’s Redhawk neighborhood and has spent most of his adult life working roofs across the Inland Valley and Pomona corridor. He picked up construction fundamentals at Palomar College before spending years in the field learning what Southern California’s UV exposure and Santa Ana wind patterns do to shingle systems. That hands-on experience is why we lead every Owens Corning job with an inspection, not a quote. Inspect first, recommend second. We repair when repair is honest, and recommend replacement when patching would waste your money. If you’re looking for broader Owens Corning sales & service context, our brand page covers the full scope of what we do.

Common Owens Corning Roofing Problems We Solve in Pomona
- Granule loss on south- and west-facing slopes. Pomona’s afternoon heat is relentless, and on Oakridge and Duration roofs we regularly see granule thinning where the UV load is highest. Exposed fiberglass mat means accelerated aging, and if you wait, the deck under those shingles starts to suffer. We assess granule loss by slope, not just by square footage, so you’re not replacing shingles that still have years left.
- Drip-edge cracking on older 3-tab Supreme roofs. Sun-baked shingles along the roof edge crack and curl where the afternoon heat hits hardest. On Pomona’s pre-war bungalows, those edges often sit over original skip-sheathing, which compounds the problem: when the shingle fails, there’s less solid decking beneath it to hold a repair.
- Wind-lifted ridge caps and edge shingles after Santa Ana events. Winds out of the Cajon Pass funnel straight through the Pomona Valley. After a dry wind event, we get clusters of calls in the same blocks near the valley’s wind gaps. Ridge caps and edge shingles lift first, especially on decades-old installs where nailing was marginal to begin with.
- Leaks at vents, valleys, and penetrations from dried-out underlayment. Beneath older Owens Corning layers, the original felt or synthetic underlayment dries out over 20-plus years of Pomona sun. The shingles may still look serviceable, but water finds those dried seams around penetrations. A leak at a pipe boot or valley on an older Owens Corning roof usually means the underlayment has given up, not just the flashing.
- Re-sheeting needs on non-uniform decks. Because Pomona roofs weren’t built to a single tract spec, we frequently find skip-sheathing on 1920s Craftsman homes near downtown and board decks on mid-century ranches to the east. Owens Corning shingles perform fine over both, but only if the deck is solid. On many Pomona jobs, the deck decision matters more than the shingle choice.
Owens Corning Service in Pomona: What Local Conditions Mean for Your Roof
Pomona’s roofing identity sits somewhere no neighboring city quite matches. Down toward Lincoln Park and the downtown core, you’ll find Craftsman and Spanish Colonial homes from the 1920s with original skip-sheathing and framing that was hand-cut, not factory-trued. Drive east, and you’re on mid-century ranch homes with board decking and post-war stucco tracts built on tighter margins. There was no single builder spec across this city, which means an Owens Corning re-roof here is rarely a matter of stripping shingles and nailing new ones on. We’re matching a modern Owens Corning product to deck conditions that vary block by block, drawing on our Owens Corning service in Claremont and nearby areas. On a Craftsman near Lincoln Park, that might mean re-sheeting a rotted drip edge before laying Oakridge. On a 1960s ranch near the 91766 ZIP, it might mean overlaying fresh deck board where the original has dried and split. Deck inspection isn’t a line item; it’s the whole decision for a lot of Pomona roofs. That’s the information most homeowners don’t get from a drive-by quote.
Nolan puts it plainly: the roof either sheds water or it doesn’t, and everything else is just conversation. Around here, the deck and edge details decide which side of that line your roof lands on.
Owens Corning Models & Products We Service in Pomona
We work on the full range of Owens Corning residential roofing products, from the Supreme and WeatherGuard 3-tab lines still found on older Pomona homes to the Oakridge and Duration architectural series that dominate newer re-roofs. Our crews know the TruDefinition Duration series well, including its nail line and installation quirks, and we understand how each product has actually aged under Inland Empire conditions, not just what the spec sheet says.
When a repair makes sense, we match Owens Corning shingles and accessories to the existing roof and insist on quality underlayment and flashing rather than cheap substitutes. We keep common Owens Corning colors and accessory components available locally so Pomona repairs don’t stall waiting on a distributor. When a roof is 20-plus years old and granule loss or wind damage is widespread, we tell you directly that a full replacement beats patching. We match the material to your roof, not your roof to our inventory.

AfterOwens Corning Service Pricing in Pomona
Owens Corning roof repair in Pomona typically runs from $350 to $1,200 for shingle replacement, leak repair, or edge work, while a deck re-sheeting with new Owens Corning shingles will push the number higher depending on how much decking must come out. Re-sheeting a full Pomona roof often adds $1,800 to $4,500 to the project, because you’re paying for the plywood or OSB, the tear-off labor, and the new Owens Corning product on top. We are not the cheapest option in Pomona, and we won’t pretend to be. What you get is an inspection that identifies the actual failure before any price is quoted, and a written estimate that spells out decking, underlayment, flashing, and shingle costs separately. Shingle Replacement, Leak Repair, and Roof Decking Replacement share one process: we inspect first, then price. Call (866) 412-5697 and we’ll walk your Pomona roof before we hand you a number.

FAQs – Owens Corning Roofing in Pomona
Pomona’s afternoon sun concentrates heat along south- and west-facing drip edges, which bakes the asphalt in 3-tab and even some architectural shingles until they crack and curl. On older Owens Corning Supreme roofs, the problem is worse because the underlying deck may be original skip-sheathing that doesn’t support the shingle edge the way modern plywood would. The fix usually involves pulling the damaged courses, confirming what’s beneath them, and re-securing the edge with matching Owens Corning product over solid decking. Call (866) 412-5697 and we’ll assess what’s actually happening on your roof edge.
Yes. We match Owens Corning product by line, color, and exposure where the existing shingles are still available or a compatible current product exists. Older Supreme 3-tab colors can be harder to match exactly because Owen Corning has cycled through color runs over the years, but we’ll tell you honestly if a patch will be visible from the street before we do the work. For most Pomona homes, a wind-damaged edge or valley can be repaired with a close enough match that no one notices except you, and only when you look for it.
Sometimes, but not usually after 30 years. If the shingles have already lost significant granules and the underlayment is dried out, a patch just moves the leak to the next weak seam. On Pomona homes where the deck is original skip-sheathing or split board, that’s doubly true: the failure below the shingles is already underway. We’ll show you what the deck looks like once we pull a damaged section, and then you can decide whether repair or replacement fits your budget. We repair when repair is honest, and we’ll never sell you a tear-off when a patch would hold.
We inspect the deck during the tear-off and re-sheet where it’s rotted, split, or no longer holds fasteners. On Pomona’s older Craftsman and Spanish Colonial homes near downtown, the original skip-sheathing often needs re-sheeting at the edges and around penetrations, even if the field decking is sound. On mid-century ranches, we may only replace a few boards. You’re not paying for a full re-sheet unless the deck actually needs it, and our written estimate will separate decking labor and materials from the shingle cost so you know exactly where your money goes.
No. Baycrest Roofing is an independent Los Serranos Owens Corning service provider, not affiliated with or authorized by the manufacturer. That independence matters for you because our recommendation is based on what your Pomona roof needs, not on meeting a brand program’s volume requirements or warranty tiers. We install Owens Corning products because they’re the right material for a given roof, and when another of our seven brands fits better, we’ll say so plainly.
