Owens Corning Construction in Fontana, CA
We’re Key Step Construction, an independent Fontana General Contractor and Owens Corning service provider. We install, repair, and replace Owens Corning roofing systems across the city’s split housing stock, from postwar tract homes to newer tile-roof subdivisions. What makes our work different here is that we read the ground movement, the heat, and the wind before we ever touch a shingle. Call (855) 382-0824 for a free estimate.
Noel Garrity, our owner, studied construction technology at Santiago Canyon College and has spent years working through the kind of remodels and additions that hold up quietly for decades. His approach carries into every Owens Corning service and Fontana roof we handle. We plan the scope, work the details, and keep one contractor accountable from tear-off to final inspection.
Why Fontana Residents Choose Us for Owens Corning Service
We know Owens Corning products from the deck up. Oakridge®, Duration®, TruDefinition® Duration®, and Supreme® shingles each behave differently under Fontana’s specific conditions, and we’ve handled enough of them to understand the failure patterns before they become leaks. Being local to Fontana means we know the housing stock, not just the product line.
Our Owens Corning work covers the full scope. We use genuine Owens Corning shingles and matching accessory components like starter strips, hip and ridge, and ventilation for warranty-eligible repairs and replacements. When an aftermarket underlayment or flashing outperforms the OEM equivalent under Fontana’s heat and wind, we recommend it and explain why. The honesty works better than pretending every OEM part is the best fit.
One contractor. Every system. That’s how we operate across Fontana.

Common Owens Corning Construction Problems We Solve in Fontana
- Oakridge® granule loss on south- and west-facing roofs in 92335: Fontana’s regular 100°F+ summers bake the surface of older Oakridge® shingles, especially when attic ventilation is weak. We see accelerated granule loss and surface cracking on homes where the roof takes direct afternoon sun. The repair usually involves more than shingle replacement, because the ventilation deficit has to be fixed or the new shingles fail the same way.
- Duration® Series wrinkling over skip sheathing in postwar homes: Many 1950s and 1960s tract homes in Fontana were built with skip sheathing and minimal underlayment. When Santa Ana winds and heat cycling expand the substrate, Duration® Series shingles can wrinkle and telegraph deck movement. A proper re-roof here means addressing the deck and underlayment, not just laying new shingles.
- TruDefinition® Duration® sealant failure on low-slope sections: Shallow-pitch roof sections on older Fontana homes rarely get the sealant bond the product was designed for. When the sealant strips on TruDefinition® Duration® shingles fail to seal fully, winter storm winds lift the tabs. We remediate the slope and sealing conditions before re-installation, because replacing the shingles without fixing the underlying issue is a repeat failure waiting to happen.
- Supreme® shingles without proper underlayment at valleys and flashings: Budget re-roofs in Fontana often skipped ice-and-water or high-temp underlayment at the valleys and wall flashings. The rare but intense winter rain storms then find every weak point. We repair these leaks correctly, adding the underlayment that should have been there in the first place.
- Roof-to-wall flashing stress from ground movement in 92335: The expansive clay soils under Fontana’s older tracts have produced decades of drought-cycle movement. We read hairline stucco cracks and slab-edge separation as a signal that roof-to-wall flashings have probably been stressed too. That connection is something a generic roofing contractor often misses.
Owens Corning Service in Fontana: What Local Conditions Mean for Your Project
There’s a pattern we see in Fontana that you won’t find in a neighboring city like Rialto Owens Corning service areas or Rancho Cucamonga, because it’s tied to the specific housing stock and soil conditions of the older 92335 tracts. Those postwar stucco-on-slab homes sit on expansive clay soils that have cycled through decades of drought and intermittent wet years. The result is hairline stucco cracks and slab-edge separation that show up on the walls first. What most homeowners don’t realize is that those same ground movements stress the roof-to-wall flashings at the exact same time.
We regularly find that a home with visible stucco cracking near the eaves also has flashing that has pulled away from the wall by a fraction of an inch. Not enough to see from the ground, but enough for wind-driven rain to get behind the Owens Corning shingles during one of Fontana’s rare winter storms. In newer Pedley Owens Corning service areas and post-tension slab subdivisions north of the 210 in 92336 and 92337, we see far less of this. The slabs don’t move the same way. So when someone in the older tract asks us to repair a few lifted tabs, we look at the wall flashing first. It’s the kind of detail that only comes from working in Fontana long enough to recognize the pattern.

AfterOwens Corning Service Pricing in Fontana
Pricing for Owens Corning roofing work in Fontana depends on the roof’s size, pitch, deck condition, and whether we’re repairing or replacing. Here’s what you can expect for the most common scopes:
| Service | Typical Fontana Range |
|---|---|
| Roof Repair | $400 – $1800 |
| Roof Replacement | $8000 – $20000 |
| Tile Roof Repair | $600 – $2500 |
| Metal Roof Installation | $15000 – $40000 |
What drives the final number is usually the deck. A 1950s Fontana home with skip sheathing and stressed flashings costs more to re-roof correctly than a 1990s house with a clean plywood deck. Our free estimate includes a written line-item quote so you know exactly where the money goes. Call (855) 382-0824 to schedule yours.

FAQs – Owens Corning Construction in Fontana
Yes, but we do it by addressing the deck first. Older Fontana homes in 92335 often have skip sheathing that’s warped, gapped, or too thin for a modern Owens Corning system. We re-sheath where needed, upgrade the underlayment to handle Fontana’s heat and wind, and then install the shingles to the manufacturer’s spec. Skipping the deck work means the new roof fails the same way the old one did. Call (855) 382-0824 for an inspection and a scope that’s honest about what the deck needs.
Oakridge® shingles on south- and west-facing 92335 roofs suffer accelerated granule loss and surface cracking after repeated 100°F+ summers, especially where attic ventilation is inadequate. Tile roofs in 92336 and 92337 handle direct sun better because the tile material resists UV degradation. When we install Owens Corning shingles in Fontana, we prioritize attic ventilation upgrades alongside the roofing. A properly vented roof is the difference between a shingle roof that lasts 20 years and one that’s shot in 12.
In most cases, yes. Isolated lifted tabs or a few missing shingles after a Santa Ana wind event are repairable without a full replacement. We match the existing Owens Corning shingle line and color, reseal the surrounding area, and replace any damaged underlayment. If the storm damage exposed widespread granule loss or multiple active leaks on an already aging roof, replacement becomes the better long-term spend. We’ll tell you straight which one applies to your Fontana roof. Call (855) 382-0824 for an honest assessment.
Yes, when we install a full Owens Corning roofing system to manufacturer spec, the system warranty applies. We handle the documentation and registration. We also stand behind our workmanship with our own warranty. The key is that a system warranty requires the full Owens Corning component set: shingles, starter strips, hip and ridge, and ventilation. We won’t cut corners on that list to save a few dollars up front.
Roof repair in Fontana typically runs $400 – $1800 depending on the extent of the damage. Full roof replacement runs $8000 – $20000, driven by roof size, pitch, deck condition, and whether you’re in an older 92335 tract home or a newer 92336/92337 subdivision. The decision between repair and replace comes down to the roof’s age, the deck’s condition, and how widespread the damage is. Call (855) 382-0824 for a free estimate with a written breakdown of both options if you’re on the fence.
