We provide independent CertainTeed roofing service across Ontario, CA, using OEM-compatible parts and manufacturer-backed materials for Ontario Roof Repair and full replacements.

Why Ontario Residents Choose Us for CertainTeed Service

Dylan Pace, who leads Crestview Roofing, grew up in Glassell Park patching flat roofs on postwar bungalows near Certainteed in Rancho Cucamonga. He learned early that a roof in a hot, dry climate fails differently than one near the ocean. Ontario sits in that same inland heat zone, where CertainTeed’s asphalt shingles bake through July and August, then get hammered by sudden Santa Ana gusts that test every seal strip and nail pattern.

We don’t guess at what’s wrong. Our technicians photograph the damage, explain it in plain terms, and hand you a written price before any work starts. That’s The Relay Visibility Guarantee in action. Every repair carries our 365-Day Done Right Promise, in writing, included with every job. If something we fixed fails within a year, we come back and make it right at no charge.

We stock OEM-compatible CertainTeed components for fast turnaround, and we pull permits when Ontario requires them. You’ll know who’s arriving, when they’ll get there, and exactly what it costs. No four-hour windows. No price ballooning at the door. Every promise in writing – that’s just how we do it.

Common CertainTeed Roofing Problems We Solve in Ontario

• Thermal cracking in Landmark Solaris and Presidential Shake lines. Ontario’s 100°F-plus summer days and rapid evening temperature drops cause asphalt shingles to expand and contract aggressively. We see this most in north-facing sections where morning sun hits cold shingles suddenly. The cracks start hairline-thin, then widen until water finds its way through during rare but heavy winter rains.
• Seal-strip failure after Santa Ana wind events. CertainTeed’s self-sealing adhesive strips soften in Ontario’s heat, then get tested by 40-60 mph Santa Ana gusts that roll through the Inland Empire. Once the seal breaks, shingles lift and crease. We replace individual shingles with matching OEM-compatible units rather than spot-sealing, which never holds long-term in this climate.
• Granule loss accelerated by UV exposure. Ontario averages 280 sunny days yearly. That UV intensity strips protective granules from CertainTeed’s organic-mat shingles faster than manufacturer projections suggest for moderate climates. We assess whether the underlying mat is still viable or if the roof has crossed into replacement territory.
• Flashing separation at valley and wall junctions. The combination of thermal cycling and low annual rainfall in Ontario means homeowners often miss slow leaks. By the time water stains appear inside, the OSB or plywood beneath has degraded. We remove the damaged decking, replace it, and reinstall valley flashing with proper overlap for this region’s occasional cloudburst intensity.
• Improper initial installation on Ontario’s 1980s-2000s tract homes. Many neighborhoods east of Haven Avenue and south of the 60 Freeway were built fast during boom years. We regularly find CertainTeed roofs with insufficient nail placement, missing starter strips, or valleys that were never properly woven. These aren’t material failures; they’re workmanship problems that we correct to manufacturer specs.

CertainTeed Service in Ontario: What Local Conditions Mean for Your Roof

Ontario’s geography creates a specific roofing environment that coastal California simply doesn’t replicate. The city sits at the western edge of the Inland Empire, where the San Gabriel Mountains block marine influence and trap heat. Summer temperatures routinely hit 105°F, and the relative humidity drops into the teens. That dry heat is brutal on asphalt shingles. The asphalt binder in CertainTeed’s composition lines slowly volatilizes, turning flexible shingles brittle years ahead of their rated lifespan.

Then come the Santa Anas, typically October through March but increasingly unpredictable. These aren’t gentle breezes. They hit with sustained force that tests every fastener and adhesive bond. We’ve worked on homes near Ontario Mills where entire shingle tabs peeled back after a single wind event, not because the shingles were defective, but because the climate combination here exceeds what standard installation practices in milder zones can handle.

We account for this in our repair and Roof Replacement – Ontario specifications. Higher nail placement, enhanced underlayment in valleys, and sealant booting in critical areas. These aren’t upsells. They’re how you get a CertainTeed roof to actually last in Ontario.

CertainTeed Models & Products We Service in Ontario

We work with the full CertainTeed residential line: Landmark, Landmark Solaris, Landmark Pro, Presidential Shake, Presidential Solaris, NorthGate SBS-modified shingles, and Carriage House. We also service Integrity Roof System installations, including DiamondDeck underlayment and WinterGuard ice-and-water barrier where Ontario’s occasional freeze-thaw cycles demand it.

Our inventory focuses on the colors and styles most common in Ontario’s established neighborhoods: weathered wood, driftwood, and charcoal tones that dominate the 91761 and 91764 ZIP codes. We source OEM-compatible components, not generic aftermarket substitutes. That means matching granule color, proper seal-strip chemistry, and manufacturer-warrantied underlayment when a full system replacement is needed. For repairs, this gets us same-day completion on most calls. For replacements, it means your warranty paperwork is clean and transferable.

We are an independent CertainTeed service provider. We are not a CertainTeed-authorized or manufacturer-affiliated contractor. Our expertise comes from years of hands-on installation and repair, not from a certification program.
