Fontana’s housing tells two stories. South and central Fontana, ZIP 92335 especially, holds thousands of postwar homes built for Kaiser Steel workers, many with original low-slope sections covered in built-up roofing that’s now fifty to seventy years old. North Fontana’s 1990s-2000s master-planned communities wear concrete and clay S-tile that looks solid from the street but often hides disintegrated felt underneath. We’ve worked both sides of town since 1984. We know what fails here, and we know what holds.

Our Specialty Roofing Services in Fontana
TPO Roofing
TPO single-ply membrane has become our most specified replacement for aging built-up roofs in south Fontana’s 92335 tract homes. The white reflective surface drops attic temperatures measurably during those 105°F July stretches, and the heat-welded seams hold against the wind gusts that funnel through Cajon Pass. A typical Roof Replacement & Installation - Fontana with TPO on a 1,500-square-foot flat or low-slope section runs $7,500-$12,000 including tear-off and proper insulation board. We install TPO from GAF and CertainTeed, authorized lines with full manufacturer backing.
Built-Up Roofing
Built-up roofing, or BUR, still has a place on Fontana’s older commercial and multi-family structures, and on some residential additions where matching existing height and drainage matters. We replaced a flattened built-up roof on a 1960s tract home in south Fontana (92335) where decades of 105°F summers had turned the original felt underlayment to powder, requiring a complete tear-off and new TPO membrane. The homeowner resisted at first, thinking the tile surface looked fine, but we showed them the crumbling felt beneath. For properties where BUR remains appropriate, we install multi-ply systems with modified bitumen cap sheets for added flexibility against thermal cycling.
Modified Bitumen
Modified bitumen bridges the gap between traditional BUR and modern single-ply. The APP and SBS formulations we install stand up to Fontana’s extreme UV better than standard asphalt, and the torch-applied or self-adhered seams resist wind uplift in ways that matter on roofs exposed to Cajon Pass gusts. Expect $5,500-$9,500 for a typical residential modified bitumen re-roof in Fontana, depending on layers removed and deck condition. We stock Atlas and Tamko modified products for faster turnaround on local jobs.
Solar Ready Roofing
With Net Energy Metering changes driving rush installations across the Inland Empire, we’re seeing more Fontana homeowners need roofs that can support panel loads for twenty-five years without a mid-cycle replacement. Our Specialty Roofing team evaluates structural capacity, designs drainage around rack penetrations, and specifies membranes compatible with solar thermal expansion. Doing the roof right first saves the $8,000-$15,000 cost of removing and reinstalling panels later.
EPDM Roofing
EPDM rubber membrane remains a cost-effective choice for detached garages, patio covers, and some commercial applications in Fontana. The black surface absorbs heat, which can be managed with proper insulation but makes it less ideal for occupied spaces without climate control. We install EPDM from authorized manufacturer lines with full warranty registration.
Green Roof
Intensive and extensive green roof systems are niche in Fontana’s arid climate but viable for commercial clients pursuing LEED certification or stormwater management credits. We design irrigation-integrated assemblies with root-barrier membranes and drainage composites specified for high-UV, low-rainfall environments.

Trusted Brands We Service in Fontana
We are authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Fontana customers, this means no substitution games. The product specified on your estimate is the product on your roof, with manufacturer warranty registration completed before we leave. We maintain local inventory of common TPO and modified bitumen rolls, cap sheets, and fastening systems so Fontana jobs aren’t held up waiting on a warehouse in Phoenix. When your north Fontana tile roof needs matching Boral clay S-tiles, we source from regional stock rather than forcing a close-enough substitute.
Common Specialty Roofing Problems We See in Fontana Homes
- Wind-lifted shingles and cracked concrete tiles. Fontana sits at the base of Cajon Pass, the mountain gap where the San Gabriel and San Bernardino ranges meet. Santa Ana and Diablo winds funnel through this gap at velocities that routinely lift unseated shingles and crack or displace concrete tile. This failure pattern is measurably more frequent here than in neighboring Rialto or Ontario to the west. Every Fontana estimate we write includes a dedicated wind-damage inspection protocol.
- Underlayment dry-rot beneath intact tiles. Contractors working north Fontana tile subdivisions (92336) consistently find that homeowners resist re-roofing quotes because the concrete tiles look intact. But the original 15-lb felt underlayment installed in the mid-1990s has baked into powder under those tiles. The roof is one hard rain or wind event away from interior damage while appearing perfectly fine from the curb. We cut test squares to show homeowners the actual condition.
- Accelerated granule loss and asphalt fatigue. Fontana regularly logs summer highs above 105°F with some of the highest UV exposure in Southern California. Asphalt shingles lose protective granules faster here than in coastal markets, and the underlayment beneath dries and cracks. Combined with overnight temperature drops off the nearby mountains, the daily thermal cycling adds mechanical fatigue stress that shortens effective roof lifespan compared to less thermally extreme Inland Empire cities.
- Failed built-up roofing on postwar tract homes. South and central Fontana’s 1950s-1970s housing stock includes thousands of homes with original or once-replaced built-up roofing on low-slope sections. After fifty to seventy years of 105°F summers and cold winter nights, the multiple asphalt and felt layers have often compressed, cracked, or begun admitting water at seams and penetrations. Repair patches buy time; full replacement with modern membrane systems solves the problem for decades.

What moves the number: deck replacement adds $2-$4 per square foot; multiple layers of old roofing add tear-off labor; steep pitches or limited access require staging; and Fontana’s wind exposure may trigger code requirements for enhanced fastening patterns.

FAQs - Specialty Roofing in Fontana
The felt underlayment beneath your tiles has failed while the concrete surface remains intact. In north Fontana’s 1990s-2000s subdivisions, the original 15-lb felt was never designed to survive thirty years of 105°F UV exposure. It turns to powder. Water finds the gaps. We cut test squares to confirm, then quote underlayment replacement without necessarily replacing the tiles themselves. Call (877) 367-1429 for a free inspection.
Fontana’s position at the base of Cajon Pass funnels Santa Ana and Diablo winds into concentrated, high-velocity streams that lift unseated shingles and crack or displace concrete tiles. This failure pattern is measurably more frequent in Fontana than in neighboring Rialto or Ontario to the west, which sit outside the primary funnel. Our Fontana Emergency & Storm Damage inspection protocol checks for lifted edges, cracked tiles, and compromised fastening patterns that other cities rarely see. Call (877) 367-1429 after any major wind event.
TPO single-ply membrane with proper insulation board outperforms asphalt-based systems in Fontana’s climate. The white reflective surface reduces thermal load, and the heat-welded seams resist both UV degradation and wind uplift. Modified bitumen with APP formulation is a strong second choice for applications where TPO isn’t suitable. We install both from authorized manufacturer lines with full warranty backing. Call (877) 367-1429 to discuss which system fits your roof geometry and budget.
Replace it. A 1960s built-up roof in south or central Fontana (92335) has endured sixty-plus years of extreme UV, thermal cycling, and occasional ponding. Patches hold briefly, but the underlying felts are brittle and the asphalt layers have lost flexibility. Full tear-off to decking, with replacement by TPO or modified bitumen, gives you twenty to thirty years of service versus two to five from repeated repairs. We quote both options honestly. Call (877) 367-1429 for a free evaluation.
Twice yearly: once in late spring after the Santa Ana season ends, and again in early fall before the winds return. Fontana’s combination of funneled wind exposure and extreme thermal cycling creates wear patterns that accelerate between seasons. Our $89 Seasonal Tune-Up includes a full photo-documented inspection with written findings. For homes in 92336 with mid-1990s tile roofs, we recommend the first inspection without delay. Call (877) 367-1429 to schedule.
