AfterRoofers in Ontario, CA
Ontario homeowners typically pay $280-$520 for concrete tile repair and $12,500-$24,000 for full roof replacement, with most jobs scheduled within 48 hours. The city’s position in the Pomona Valley wind corridor and its concentration of 1980s-2000s tile-roofed tract homes create roofing challenges you won’t find in coastal markets. We’re Tilehurst Roofing, a Kingswell family company, and our crews work Ontario from the Inland Empire office. Call (945) 303-9821 to schedule your free estimate.
Why Ontario Homes Are Different
Ontario sits directly downwind of the mountain passes that funnel Santa Ana winds into the Inland Empire basin. During Santana events, gusts routinely exceed 60-70 mph. Because San Bernardino County fire codes have long mandated Class A fire-rated roofing near the wildland interface, the overwhelming majority of Ontario homes carry concrete tile. Those tiles get lifted, cracked, and displaced by wind far more dramatically than shingle roofs. Every significant Santa Ana event triggers a wave of emergency tile-reset and compromised-underlayment calls that defines our local business cycle.
The housing stock reinforces this pattern. Along the historic Euclid Avenue corridor and near downtown, 1920s-1950s bungalows and citrus-era ranch homes still carry aging wood shake or early composition shingles well past their service life. But citywide, the dominant stock is 1980s-2000s stucco tract homes uniformly topped with concrete tile. Most roofing work here involves tile systems, not asphalt shingles.
Summer temperatures of 105-110°F bake underlayment and accelerate brittleness faster than in coastal California cities. Degraded underlayment under lifted tiles is the primary leak pathway after wind events. Intense UV and thermal cycling also crack mortar-set tile beds over time, loosening tiles before any wind arrives. On 1990s Ontario tract homes, tiles were commonly set with minimal mortar and no secondary fastening clips. After 25-plus years of 110°F attic heat cycles, those tiles are barely seated, and a single strong Santana can strip an entire field of a west- or north-facing slope before the homeowner wakes up.
Our Main Ontario Services
Most calls from Ontario fall into three categories: ongoing maintenance and inspection, targeted repair after wind or heat damage, and full replacement when the system has reached end of life.
Roofing Company in Ontario
We handle inspections, maintenance programs, and preventative work for Ontario’s tile-heavy housing stock. Our crews know how to spot the pre-failure signs specific to this market: hairline mortar cracks from thermal cycling, clip corrosion in 1990s installations, and underlayment embrittlement that coastal inspectors often miss. Every inspection concludes with a written condition report and, if work is needed, a fixed price before any materials are ordered. Roofing Company in Ontario.
Roof Repair in Ontario
Wind events, thermal damage, and age-related mortar failure drive most repair calls here. We stock replacement tiles from Atlas, Tamko, and Boral to match existing fields without the month-long wait for special orders. Our crews carry the secondary fastening clips that 1990s homes lack, and we install them during reset work to prevent repeat blow-offs. Every repair carries a written guarantee before we leave the site. Roof Repair in Ontario.
Roof Replacement in Ontario
When underlayment is degraded throughout, tile beds have failed systemically, or the decking shows moisture damage, replacement becomes the cost-effective path. We strip to deck, assess for heat-related structural wear unique to Ontario’s attic environments, and reinstall with current fastening standards and your choice of seven manufacturers. The written price covers complete tear-off, disposal, new underlayment, and installation, with no change orders once work begins. Roof Replacement in Ontario.

What Ontario Customers Say
"Had a leak over the kitchen every time it rained hard. Two other roofers wanted to replace the whole roof. Tilehurst found the bad flashing, fixed it, and it's been dry through three storms since. Honest people."
- Gary Whitfield"The estimator climbed up, took photos, and showed me the actual problem areas instead of just talking. No pressure to replace anything that didn't need it. Repair's held up great."
- Tom Easley"Gutters and a section of shingles after a big wind. Answered the phone right away, came when they said, and the price on the quote is what I paid. Easy to deal with."
