Owens Corning Roofing in Ontario, CA | Bedrock Roof Repair
We provide independent Owens Corning roofing service across Ontario, CA, from the 1950s stucco tracts near downtown to the warehouse roofs along the 10 and 60. The one thing that separates our Owens Corning work here is that we’re reading your roof against Ontario’s specific wind corridor and heat profile, not a national average. If you need a straight diagnosis on an Owens Corning roof in Ontario, call (833) 589-7850.

We are not an Owens Corning authorized contractor, and we don’t pretend to be. What we are is a roofing crew that works with Owens Corning shingle and underlayment systems regularly enough to know exactly how they fail in this city. Bedrock Roof Repair installs and repairs Duration, Oakridge, and Supreme lines across Ontario, and we spec them honestly, whether that means a targeted repair or a full tear-off. Alan Cofield, our owner, grew up reading roofs the way most people read street signs, and he trained in the building trades program at Cypress College before spending nearly two decades working Orange County roofs. He runs our Ontario jobs with the same repair-first lens: we tell you what the roof actually needs, not what’s easiest to invoice.
Why Ontario Residents Choose Us for Owens Corning Service
We’re familiar with how Owens Corning materials behave after twenty Ontario summers. That’s not a slogan. Supreme three-tab shingles on a 1958 hip roof in 91762 fail differently than Duration architecturals on a 2003 two-story off Euclid, and we can tell you which failure you’re looking at before we climb the ladder. We carry genuine Owens Corning shingles, starter strips, and hip-and-ridge accessories for match work, and we use quality aftermarket flashing and pipe boots where the OEM part adds cost without adding life. The point is that we know the systems cold and we’re not locked into a single supplier’s line, because Owens Corning sales & service is one of seven major brands we work with, not the only one. That matters when the honest answer is a repair on an Oakridge field rather than a full replacement. Alan’s approach is simple: the roof tells you what went wrong. You just have to know how to read it.

Common Owens Corning Roofing Problems We Solve in Ontario
- Granule loss and brittleness on Supreme three-tab shingles. In Ontario’s 1950s and 60s tracts, particularly 91761 and 91762, original Supreme shingles bake through summers that regularly cross 100°F. The asphalt dries out, granules shed, and the mat gets exposed. Wind at the eaves lifts tabs before the sealant can hold. We see this most on single-story stucco homes near downtown.
- Seal-strip failure on Oakridge and Duration hip-and-valley roofs. Santa Ana gusts peel back tabs before the sealant re-adheres, especially in the cooler months when the shingle surface doesn’t get hot enough to bond. It looks like wind damage, but it often starts weeks earlier as a seal that never set.
- Underlayment failure beneath concrete clay tile. This is the classic Ontario leak that looks like a tile problem. The original builder’s Owens Corning felt or shingle underlayment sits under the tile, bakes for fifty years, and tears at the lap seams. The tiles above look fine. Water gets through anyway. 91762 is full of these.
- Attic heat trapping in two-story stucco homes. Poorly vented attics on 1980s and 2000s subdivisions trap Inland Empire heat, which accelerates shingle aging and kills flashing sealant at pipe boots and wall flashings. The shingle looks fifteen years older than it is.
- Tile displacement after Santa Ana wind events. Slipped or broken concrete clay tiles on 1950s and 60s hip roofs are the first call we get after a wind blow. The matching tile is usually out of production, so techs end up salvaging builder’s spares or hitting salvage yards along Holt Blvd before they even address the underlayment beneath.
Owens Corning Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario’s roofing market splits along the Santa Ana River wind corridor and the 10/60 freeway divide, and that split shapes every Owens Corning roof we touch. In the older post-war tracts of 91761 and 91762 near downtown and the Edison Historic District, we’re mostly dealing with 1950s and 60s single-story stucco homes where the original Owens Corning underlayment sits beneath concrete clay tile. After a Santa Ana event, those roofs shed tiles, and because the matching tile is long out of production, we scrounge the builder’s spares or salvage yards along Holt Blvd before touching a single shingle layer. A few miles east and south, along the 10 and 60 corridors in 91764 and 91761, the work flips to low-slope commercial and warehouse roofs tied to Inland Empire distribution growth. That’s a different Owens Corning conversation entirely, flat membranes and edge detailing that most roofers in Chino or Rancho Cucamonga don’t juggle the way an Ontario roofer does. We do both, and that dual load is exactly what makes our Owens Corning work here honest: we know the difference between a wind-damaged tile repair and a membrane seam failure because we see both in the same week.
Owens Corning Models & Products We Service in Ontario
We service the Owens Corning lines most common across Ontario: Oakridge architectural shingles on 1980s through 2000s south and east side subdivisions, Duration and Duration Designer on recent tract re-roofs, and Supreme and Classic three-tabs still hanging on original 1950s and 60s roofs. For higher-wind sections of Ontario, we spec TruDefinition Duration with SureNail Technology and Owens Corning synthetic underlayment where the roof calls for it. Our parts approach is simple: genuine Owens Corning shingles and underlayment-matched accessories when matching the original roof, and quality aftermarket flashing and pipe boots where the OEM piece doesn’t earn its cost. We keep the common Duration and Oakridge colors and starter strips stocked for fast turnaround on Ontario repair jobs, and we can order anything else from our local suppliers without the multi-week wait.

AfterOwens Corning Service Pricing in Ontario
- Roof inspection (Owens Corning or any shingle system): $150 – $350 depending on roof complexity and access
- Shingle leak repair, localized (1 – 3 shingles, sealant, small flashing fix): $250 – $500
- Larger shingle section or underlayment repair beneath clay tile: $500 – $1,200 depending on tile salvage and underlayment condition
- Full Owens Corning re-roof (tear-off, underlayment, architectural shingle): $8,000 – $18,000+ depending on roof size, pitch, decking condition, and whether tile salvage is involved
What drives the cost in Ontario is access and decking. A 1958 single-story hip roof with concrete clay tile costs more labor per square than a 2005 two-story with a straight shingle deck, because every tile movement is hand work and the underlayment below usually needs attention. Our free estimate includes a written line-item quote, and we walk the roof before we quote. Call (833) 589-7850 to set one up, and we’ll tell you whether you’re looking at a repair or a full replacement, without the upsell.

FAQs – Owens Corning Roofing in Ontario
The tiles are not your waterproofing. The original Owens Corning underlayment beneath them is, and after fifty Ontario summers it bakes, shrinks, and tears at the lap seams. Water gets through the overlaps and finds your ceiling. We see this in 91762 constantly. Call (833) 589-7850 and we’ll check the underlayment before we touch a tile.
We’re an independent installer, so the manufacturer’s material warranty on Owens Corning shingles is between you and Owens Corning. Our workmanship is backed by our own warranty, and we walk you through the exact terms before the job starts, in writing. Nothing vague. If you want to talk specifics for your Ontario roof, call (833) 589-7850.
For most 91761 homes coming off original Supreme or Classic three-tabs, we spec Duration architectural shingles. The dimensional look matches what most Ontario tract homes are going to now, the wind performance handles the Santa Ana gusts better, and the material cost difference is modest. Oakridge is the budget-conscious alternative that still looks finished. Your roof’s pitch and decking determine the final call, and our estimate is free.
One good winter rain is all it takes. The exposed underlayment tears, water gets under the remaining tile, and the stain on your ceiling shows up weeks later. We answer wind-related calls in Ontario quickly because the damage compounds. If tile has slipped, call (833) 589-7850 and we’ll get eyes on it before the next storm.
Yes. We work single-family Owens Corning shingle and tile-underlayment roofs in 91761 and 91762, and we handle low-slope commercial roofing along the 10 and 60 corridors in 91764 and 91761, plus Upland Owens Corning service.
