Owens Corning Construction in Claremont, CA | Elmwood Contractors
We install Owens Corning roofing systems across Claremont as an independent Claremont General Contractor, not an authorized dealer or manufacturer affiliate. What makes our Owens Corning work different here is simple: we spec the roof to the house, the design review board, and the wildfire zone rather than slapping the same shingle package on every home. If you’re planning a roof replacement on a 1920s Craftsman or a foothill ranch, call (866) 253-8554 for a free estimate. We’ll tell you exactly which Owens Corning products fit the job and why.
Why Claremont Residents Choose Us for Owens Corning Service
Claremont is not a place where you can drop a generic asphalt roof on a historic bungalow and call it done. The Claremont Colleges bring an architectural expectation to the surrounding neighborhoods, and the Village’s preservation ethos has teeth. Our crews have spent years working with Owens Corning shingles on exactly these homes, so we know which Duration profiles read as appropriate on a period roofline and which ones will get flagged in design review, and we also provide Owens Corning repair in Upland for similar historic properties. Nolan Shepherd, our owner, grew up in Fullerton and cut his teeth on late-60s tract homes before spending two decades running Elmwood Contractors, and he’s the first to tell a homeowner when a manufacturer’s catalog won’t clear local scrutiny. We use genuine Owens Corning shingles, Onyx and Miami-Dade-approved underlayments, and matching accessory components on every job. No relabeled substitutes, no knockoff architectural shingles. We recommend products because they perform, not because they’re convenient for us.

Common Owens Corning Construction Problems We Solve in Claremont
- South-facing granule loss and balding on older Oakridge roofs. The inland Pomona Valley sun is relentless on south-facing slopes. We regularly see Oakridge architectural shingles on Claremont ranch homes where the granule coating has worn to the asphalt mat, with curling accelerating on the lower courses. The heat load breaks down the asphalt over time, and once the mat is exposed, the clock is ticking.
- Santa Ana wind lifting and creasing shingles nailed too high. When the winds come down the San Gabriel foothills, shingles nailed above the nailing strip or placed on low-slope sections without proper sealing are the first to go. We find creased, flapping Oakridge shingles after nearly every major wind event in Claremont. High nailing is the silent culprit.
- Red-tile tear-offs revealing Owens Corning shingles over skip-sheathing. This is a Claremont signature. On mid-century Spanish Colonial and Mediterranean Revival homes, we peel back red tile and find old Owens Corning shingles laid directly over skip-sheathing with no ice and water shield. A foothill storm that drives rain sideways soaks the decking, and by the time we see it, there’s rot in the sheathing.
- Blistering from inadequate attic ventilation on sealed-soffit ranch homes. Claremont ranch houses built in the 1950s and 60s often have sealed soffits and undersized venting. That trapped heat cooks the underside of the shingles and produces premature blistering. We flag this on nearly every Owens Corning inspection we do in 91711.
- Mismatched granule color on patch repairs from previous contractors. A partial Owens Corning repair only preserves the warranty profile if the color and granule match are right. We frequently see homes where a previous patch used a close-enough shade from a different line. It looks wrong from the street and it tells the manufacturer’s rep the roof has been touched by someone who didn’t care.
Owens Corning Service in Claremont: What Local Conditions Mean for Your Equipment
Here’s the piece nobody outside Claremont talks about. The foothill-edge streets north of Foothill Boulevard, up toward the Bernard Field Station and the wilderness park boundary, fall into Chapter 7A wildfire-resistant construction territory under California building code. That changes the Owens Corning spec in ways a stock catalog doesn’t spell out. A standard Oakridge roof replacement on a Village-adjacent Craftsman is one thing. A roof five hundred feet from the chaparral is another. Chapter 7A requires Class A fire-rated assemblies, and that means pairing Owens Corning shingles with fire-rated underlayment and ember-resistant flashing details at every eave and rake. The right material in the right place. Everything else is just catching up to that decision. We run into this constantly on homes along the base of the San Gabriel Mountains, where the wildfire risk isn’t theoretical and the insurer will ask for documentation before they renew the policy.
Owens Corning Models & Products We Service in Claremont
We install and service the full Owens Corning architectural shingle lineup: Oakridge, Duration, Duration Designer with TruDefinition color capability, and the Berkshire Collection for homeowners who want a premium dimensional look. On the parts side, we stock genuine Owens Corning shingles and Onyx underlayments locally, which keeps turnaround time down for Claremont repairs. On a partial repair, we match the existing line and the exact granule color because a mismatch doesn’t just look wrong. It voids the practical warranty profile. When we replace a roof, we run the homeowner through the difference between Oakridge and Duration at multiple tiers so they decide with their budget and the design review expectation in front of them, not after the fact.

AfterOwens Corning Service Pricing in Claremont
Roofing costs in Claremont are shaped by the age of the house, the pitch of the roof, and whether you’re in a design review zone or the Chapter 7A foothill belt. Here’s where our pricing lands across the 91711 service area:
| Service | Price Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
| Tile Roof Repair | $600 – $2,500 |
| Metal Roof Installation | $15,000 – $40,000 |
What changes the number is what’s underneath. A roof with rot in the decking, sealed soffits, or a failed tile-underlayment assembly costs more than a straightforward tear-off. That’s not a change order waiting to happen. That’s what the estimate is for. We price it before we start, and we write it down. Call (866) 253-8554 to schedule a free estimate. We’ll walk the roof with you and tell you what you’re actually looking at.

FAQs – Owens Corning Construction in Claremont
Yes. If your house sits in the Village-adjacent streets or within the historic core, a roof replacement usually triggers design review compatibility scrutiny. That means matching the original roof pitch, window proportions, and material character. A standard Duration shingle in the wrong color profile can get flagged, so we spec the roof with design review in mind from the first walkthrough. Call (866) 253-8554 if you want a second opinion before you file paperwork.
It is, but only if it’s assembled as a Class A system. Foothill-edge properties in 91711 fall under Chapter 7A wildfire-resistant construction, which means Class A shingles, fire-rated underlayment, and ember-resistant flashing details at the eaves and rakes. A standard Oakridge roof without those details won’t meet the fire-resistance expectation your insurer is looking for. We do this assembly regularly on Claremont foothill homes.
Because the south-facing slope takes the full inland Pomona Valley sun load all year. The UV exposure breaks down the asphalt mat and strips the granule coating much faster than on the shaded north slope. We see balding to the mat on south slopes of 20-year-old Oakridge roofs across Claremont while the north slope still looks serviceable. The fix is often replacement, not patching.
It depends on what’s underneath the tile. If the Owens Corning shingles were installed over skip-sheathing without ice and water shield, the decking is probably moisture-damaged and the repair becomes a re-roof, not a patch. On a 1920s Craftsman bungalow near the Claremont Colleges, our crew pulled red tile over failing Owens Corning shingles on the back slope, similar to work we do providing Owens Corning service in San Antonio Heights. We stripped to sheathing, corrected the decking and soffit ventilation, and installed Duration shingles with a fire-rated underlayment so the back slope met the insurer’s fire-resistance expectation while matching the original roofline. Call (866) 253-8554 for an exact assessment. Estimates are free.
Metal is a strong option on a ranch home with a low-slope roof in the hot Pomona Valley sun, but it’s pricier, and some Claremont design review boards push back on the profile. If your Owens Corning shingles are failing due to heat and ventilation problems rather than age, we’ll tell you whether fixing the ventilation and reinstalling Duration shingles makes more sense than a metal retrofit. Call (866) 253-8554 and we’ll price both honestly.
