Whether you own a 1990s tract home with Presidio® concrete tile or a prewar bungalow off Euclid Avenue with Grand Manor® shingles, our crew diagnoses the real problem and tells you the price before any work begins. What makes our CertainTeed work different here comes down to one thing: we understand how Santa Ana wind and 110°F attic heat tear these specific systems apart in the Pomona Valley.

Why Ontario Residents Choose Us for CertainTeed Service
Most roofing companies in the Inland Empire will install whatever is on the truck. We take a different approach. Our crew has worked on more CertainTeed systems across Ontario than we can count, and we know which failure patterns show up on which streets. Greg Holloway, the owner here at Tilehurst Roofing, learned the trade at Los Angeles Trade-Technical College from instructors who treated sloppy flashing work like a bad stitch, something you simply don’t leave behind. That standard carries into every CertainTeed job we take in Ontario. We match exposed components to genuine CertainTeed profiles when available, keep OEM-compatible accessory stock locally for fast turnaround, and put every repair guarantee in writing before the crew packs up. Since we’re CertainTeed sales & service specialists for the Inland Empire, we carry the repair parts most Ontario homes actually need, not just the common ones.
We’re an independent contractor, not authorized, sponsored, or endorsed by CertainTeed. Our only obligation is to the homeowner standing in front of us. That means when a tile can be reset, we say so. When a slope needs full underlayment replacement, we say that too, and we show you why with photos. You won’t get a sales pitch dressed up as a diagnosis.
Common CertainTeed Roofing Problems We Solve in Ontario
- Wind-stripped tile fields on 1990s tract homes. Many Ontario homes built in the 1980s and 1990s had CertainTeed concrete tiles set with minimal mortar and no secondary fastening clips. After 25-plus years of thermal cycling, those tiles are barely seated. One strong Santana event can strip an entire west-facing slope. We reset sound tiles with stainless clips and replace the damaged ones with matching CertainTeed profiles.
- Degraded synthetic underlayment under lifted tiles. CertainTeed RoofRunner™ and DiamondDeck™ underlayments work well, but 105-110°F Ontario summers bake them brittle over time. Once wind displaces a tile, the compromised membrane underneath is the primary leak path, not the tile itself. We replace underlayment in full courses, not patches, so the repair doesn’t fail at the seam next year.
- Cracked Presidio® barrel tiles and Fortex™ flat tiles. Thermal cycling expands and contracts tile against fasteners. When fasteners are overdriven or corroded, tiles crack at the fastening holes. We see this on nearly every Ontario tile roof by year 20. We replace cracked pieces with matching profile tiles and address the fastener issue so it doesn’t repeat.
- Granule loss and creasing on Grand Manor® shingles. The 1920s-1950s bungalows along the historic Euclid Avenue corridor and near downtown often still carry aging shingle roofs. Decades of UV exposure and Santa Ana flexing crease and strip granules from CertainTeed Grand Manor® and Presidential Shake® shingles. When repair is viable, we do it. When the shingle field is spent, we quote replacement honestly.
- Mortar bed failure across tile fields. The intense UV and thermal cycling in Ontario cause mortar-set tile beds to crack over time, loosening tiles before any wind event even arrives. We assess whether the mortar failure is isolated or systemic. Isolated spots get reset. Systemic failure means re-setting the slope with mechanical fastening, which is the only fix that survives the next wind season.
CertainTeed Service in Ontario: What Local Conditions Mean for Your Equipment
Ontario sits squarely in the Pomona Valley wind corridor, directly downwind of the mountain passes that funnel Santa Ana winds into the Inland Empire basin. Gusts routinely exceed 60-70 mph during Santana events. Because San Bernardino County fire codes have long mandated Class A fire-rated roofing near the wildland interface, the overwhelming majority of Ontario homes have concrete tile. That tile gets lifted, cracked, and displaced by these winds far more dramatically than shingle roofs ever do.
Here’s the detail that matters for CertainTeed owners specifically: on 1990s Ontario tract homes, certain CertainTeed concrete tile fields were set with minimal mortar and no secondary fastening clips. After 25-plus years of 110°F attic heat cycles, those tiles are barely seated. A single strong Santana can strip an entire west- or north-facing slope before the homeowner wakes up. We’ve walked up on roofs where entire courses of tile are hanging off the eave, held by nothing but the gutter. If you live in a 1990s stucco tract home in Ontario and haven’t had your tile fastening inspected, your roof may be one wind event away from bare underlayment. That’s not an exaggeration.
After a 65-mph Santana event, our crew from Ontario Roofing Company responded to a 1994 tract home near Euclid Avenue where a west-facing slope of CertainTeed concrete tiles had been stripped to bare RoofRunner underlayment. We reset the sound tiles with new stainless clips, replaced the torn underlayment on that slope, and matched new CertainTeed Presidio tile to the field. The homeowner had a dry roof by the next rain and a documented clip schedule for their insurer.
CertainTeed Models & Products We Service in Ontario
We work on the full CertainTeed lines most common in Ontario housing stock. That includes Presidio® concrete barrel tile on the 1980s-2000s stucco tract homes, Grand Manor® and Presidential Shake® asphalt shingles on older Euclid Avenue bungalows and citrus-era ranch homes, and Fortex™ flat concrete tile on mid-century builds. We also handle RoofRunner™ and DiamondDeck™ synthetic underlayment replacement under tile systems. Our parts approach is straightforward: genuine CertainTeed profiles when they are still available, and aftermarket underlayments and fasteners only where they meet or exceed the original specification. We stock common Ontario repair pieces locally so we’re not waiting on a shipment from back east when your roof is open to the sky. If you’re considering Ontario service area coverage for any roofing issue beyond CertainTeed, our crew handles that too.
CertainTeed Service Pricing in Ontario
What you pay depends on what’s actually wrong. A single cracked tile or a small lifted field often runs $250-$500 including the parts, the labor, and the guarantee. Underlayment replacement under a section of lifted tile typically lands between $1,200 and $3,200 per slope, depending on how much membrane needs to come out and whether we’re matching existing tile or resetting your sound pieces with new clips. A full slope re-set with mechanical fastening across a west-facing field on a 1990s tract home usually runs $4,000-$8,000, because every tile comes off, the underlayment gets inspected, and every piece goes back down with a fastener.
Every estimate we write includes the full scope in writing before you commit to anything. No vague allowances. No change-order creep. Greg’s rule on this is simple: know the price before the first tile moves. Call (945) 303-9821 and we’ll walk the roof with you, show you photos of what we found, and put a number on paper. The estimate is free.

FAQs - CertainTeed Roofing in Ontario
Yes, if the tiles are sound. We lift the tile field, pull the degraded underlayment, install new synthetic underlayment, and reset your existing tiles with new fasteners and clips. If your tiles are cracked or failing at the fastening holes, we’ll flag those and replace them as we go. Call (945) 303-9821 for a free inspection and we’ll tell you exactly what your roof needs.
If your home was built in the 1980s-1990s and the tiles were set with minimal mortar, yes, clips are the right fix. Wind-lifted tiles without secondary fastening will lift again in the next Santana event. We add stainless clips to the tile field as part of the reset, which also documents your wind mitigation for insurance purposes. Call (945) 303-9821 and we’ll assess whether clips are needed across the whole slope or just the lifted section.
You can’t tell from the ground, and by the time you see a ceiling stain, the underlayment has been failing for a while. The reliable way is to lift a tile and check. Brittle, cracked, or delaminating underlayment needs replacement. On Ontario homes where the underlayment is more than 20 years old, it’s usually time. We’ll check it for free during an estimate.
Yes, significantly. Standing seam metal roofs are mechanically fastened and interlocked, so they hold up to 60-70 mph Santa Ana gusts far better than mortar-set tile. Ontario homeowners who are done resetting tiles after every wind season often make the switch. We install standing seam metal as a full replacement and can walk you through the cost difference honestly. Call (945) 303-9821 for a comparison quote.
Usually, yes. We match profile, color, and texture against your existing field. Some Certainteed in Rancho Cucamonga color blends from the 1990s are still available through the company’s current Presidio and Fortex lines, and when they’re not, we source equivalent profiles from other manufacturers to blend invisibly. If we can’t match it, we’ll tell you before you pay anything. Call (945) 303-9821 with a photo of your tile and we’ll start the match.
