Owens Corning Construction in Fontana, CA | Timberline Contractors
We install and repair Owens Corning roofing systems across Fontana, from Duration shingles to Supreme underlayment and WeatherLock membrane. The work here splits between 1990s – 2000s stucco tracts in the north and older 1950s – 70s ranch homes in the central grid, which means two different deck conditions and two different shingle lifespans. We’re an independent contractor, not manufacturer-affiliated, and we bring OEM-grade parts plus local wind and heat knowledge to every job. Call (866) 253-5808 for a free estimate.
Why Fontana Residents Choose Us for Owens Corning Service
Most roofing crews in Fontana can nail shingles. Fewer understand why a Duration shingle fails at the nail line when it’s hand-nailed in 100°F heat, or why a sealant strip never activated on a south slope. That’s the difference. Nelson Fung, our owner and general contractor, learned the trade at Los Angeles Trade-Technical College and spent years on Eastside bungalow remodels before running Timberline Contractors. He still walks every Fontana roof himself before we quote it. We’re one of the few Owens Corning sales & service teams in the Inland Empire that treats the underlayment, membrane, and shingles as one system rather than a material swap. That matters because warranty coverage and adhesion both fail when brands get mixed.

Common Owens Corning Construction Problems We Solve in Fontana
- Granule loss on south- and west-facing slopes. Fontana summers routinely hit 100°F, and the sun bakes the asphalt mat on those exposures. We see Duration shingles in the 92336 subdivisions that look ten years older on one plane than the rest of the roof. Targeted slope repair usually works if caught before the mat cracks through.
- Wind-lifted tabs and exposed tar paper after Santa Ana gusts. The Cajon Pass funnels afternoon wind hard into the northern foothills. Roofers who don’t tie off staging to the forecast leave loose shingles and sheathing that the next gust rips clean. We schedule tear-offs around wind windows, not just heat.
- Nail-line failures on Duration shingles. Duration’s SureNail strip is a specific fastening zone. Hand-nailers in extreme heat miss it, and the shingle eventually backs out at the nail head. We re-nail to the strip and check every course.
- Premature sealant-strip failure at hips, ridges, and valleys. If a crew never heat-activated the sealant, Fontana’s wind-driven dust and what little rain does fall gets under the shingles. We find this on older central-grid ranch homes in 92335 and 92337 where the original roof was installed fast and cheap.
- Decking rot hidden under old tile or 3-tab conversions. The older ranch tracts near the 92335/92337 ZIPs often have decking that’s soft in the valleys. When we pull tile or Oakridge shingles, we check the substrate before laying anything new.
Owens Corning Service in Fontana: What Local Conditions Mean for Your Equipment
Fontana isn’t a coastal remodeling market. It’s a logistics hub with tilt-up warehouse shells on the valley floor and infill tract housing climbing toward the 92336 foothills. That housing split shapes every Owens Corning roof we touch. A 2002 stucco-on-wood-frame house in the north subdivisions has a different deck, different ventilation, and different shingle wear than a 1965 ranch on the flat central grid near Sierra Avenue. The north homes trap more attic heat, which accelerates asphalt aging from below while the sun works from above. The older central homes usually have thinner decking and a history of patched repairs. We also have to factor in South Coast AQMD dust rules, which apply to any tear-off or debris-generating roof work in Fontana. A crew that doesn’t plan for wind-driven dust can get a stop-work notice faster than a shingle supplier can restock. We file the dust control plan first.
On a 2002 house up in the 92336 subdivisions, we found Duration shingles on the south slope stripped of granules and lifting at the ridge after a Santa Ana event, with the sealant strips never heat-activated by the original installer. We replaced that plane with new Duration shingles, rolled WeatherLock through the valleys, and re-nailed every course to the SureNail strip, then scheduled the tear-off around the afternoon wind forecast so loose sheathing didn’t become a safety problem. Do it right the first time or explain yourself twice.
Owens Corning Models & Products We Service in Fontana
We service the full Owens Corning roofing line that makes sense in this climate. Oakridge shingles still show up on older Fontana ranch homes, and we repair or replace them as needed. Duration and Duration Premium are the most common on 1990s – 2000s houses in the north, and we know the SureNail fastening requirements cold. Supreme underlayment goes under every new roof we install. WeatherLock self-adhering membrane gets rolled through valleys, hips, ridges, and any low-slope transition. We use genuine Owens Corning accessories – matching hip and ridge caps, starter shingles – because mixing aftermarket parts with OEM shingles is where adhesion and warranty coverage die. For faster Fontana turnaround, we keep common accessory stock locally rather than waiting on distribution.

AfterOwens Corning Service Pricing in Fontana
Fontana roof pricing depends on the housing stock you’re in. A tear-off on a 1965 central-grid ranch with one layer of Oakridge costs less than a full Duration replacement on a two-story 2004 stucco in the north hills, where decking repair and steeper pitch add labor. Here’s what we quote:
| Service | Fontana 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 |
Every estimate is a written line-item quote. We walk the roof, check the decking, and tell you straight whether a repair makes sense or a replacement is the honest call. Call (866) 253-5808 to schedule yours.

FAQs – Owens Corning Construction in Fontana
Yes, if you want the manufacturer warranty to hold. Mixing another brand’s underlayment or starter strip with Owens Corning shingles voids coverage and creates adhesion problems at the edges. We use genuine Supreme and WeatherLock on every Owens Corning roof we install or repair in Fontana. Call (866) 253-5808 and we’ll walk you through what’s on your roof now.
Wind damage itself doesn’t void an Owens Corning warranty if the roof was installed to spec. What voids it is improper fastening – missed SureNail strips, wrong nail placement, sealant never activated. Those are installation failures, and the wind just exposes them. We find that pattern all over Fontana’s northern foothills. If your roof lifted after a Santa Ana event, we’ll document the fastening pattern and tell you whether it’s a repair or a warranty issue.
Heat accelerates asphalt aging. South- and west-facing slopes in Fontana can lose 30 – 40% of their useful life compared to the same shingle on a shaded north slope. That’s why we check granule loss slope by slope rather than treating the whole roof as one condition. A targeted replacement on a sun-baked plane often buys years before a full tear-off makes sense.
In most cases, yes. If granule loss is limited to one south-facing plane and the shingles aren’t curling across multiple courses, we’d rather do a slope repair with matching Duration shingles and WeatherLock in the valleys. Once shingles are curling on multiple planes or the decking is soft, replacement is the honest call. The free estimate tells you which one you’re in.
Yes. Fontana sits under South Coast AQMD jurisdiction, and a tear-off that generates visible dust without a control plan can get a stop-work notice. We file the dust plan before we start, stage materials with wind forecasts in mind, and keep debris contained. Call (866) 253-5808 and we’ll explain what your specific roof project requires.
