Roofers in Ontario, CA
Roof inspection in Ontario usually costs $180 to $340 for a full visual and moisture assessment, and it’s the smartest first move on homes built between the 1940s and 2000s here, because the Inland Empire’s sun and Santa Ana winds damage roofs differently than coastal weather does. We find cracked concrete tile from thermal cycling, lifted shingle tabs on west- and north-facing slopes, and aging flashings that fail during rare but intense winter rain events. Van Nuys Roofing Co has served Ontario since 2015, and we know which problems show up block by block across the 91758, 91761, 91762, and 91764 ZIP codes. Call (866) 321-6172 to schedule yours.
Why Ontario Homes Are Different
Ontario sits in the hot, dry Inland Empire, not the marine-layer zone of LA County. That single fact changes everything about how roofs fail here. Summer weeks above 100°F bake roofing materials day after day, and concrete tile expands and contracts enough to crack along stress lines. Santa Ana winds rip at shingle tabs on west- and north-facing slopes, particularly on 1970s tract homes where ridge caps were original and now lift under sustained gusts. We rarely see the rot and algae issues common to coastal roofs; instead we see thermal fatigue, wind exposure, and flashing failures where rare winter downpours find every weakness.
The housing mix adds another layer. Much of Ontario is post-WWII tract construction from the 1940s through the 1970s, with low-slope built-up or rolled roofing and asphalt shingles over original sheathing. Then you have 1980s through 2000s subdivisions with concrete tile, many installed under newer Title 24 cool-roof requirements that hold up far better in Santa Ana events. Older downtown and Euclid Avenue-area homes frequently have minimal attic ventilation, which accelerates shingle aging and makes inspection findings matter more. A roofer working Ontario needs to be comfortable switching from a 1950s built-up roof patch to a modern tile repair in the same afternoon. That’s exactly the range we handle.
Styles & brands we work with
Our Main Ontario Services
When Ontario homeowners call us, two services account for nearly every conversation: repairs that stop a leak before it spreads, and full replacements when the roof has reached the end of its useful life. Here’s what each one looks like in this city.
Roof Repair in Ontario
Ontario repairs usually fall into three buckets: cracked or displaced concrete tile, torn or lifted asphalt shingle tabs after wind events, and flashing failures around chimneys, vents, and roof-to-wall transitions. After a Santa Ana blow, we see a predictable pattern on 1970s tract homes: shingle tabs torn on windward slopes while tile roofs barely notice the same storm. We inspect first, identify the actual source of the problem, and repair only what needs fixing, using materials matched to your existing roof. For the full scope of repair work we handle in this city, see Roof Repair in Ontario.
Roof Replacement in Ontario
When an Ontario roof reaches the point where patches no longer make financial sense, replacement is the honest answer. That’s common on 1940s through 1970s homes where original sheathing and decades of thermal stress have compromised the entire system. We walk you through material options across seven leading brands, including Boral concrete tile and GAF or Owens Corning shingles, so the choice is driven by your roof’s pitch, exposure, and your budget, not by what we happen to stock. Permits and Title 24 cool-roof requirements matter here, and we handle that paperwork. For the full process and material options, see Roof Replacement in Ontario.

Roof Inspection in Ontario
Roof inspection in Ontario typically costs $180 to $340, and it’s the only way to know whether the cracks, lifted tabs, or aging flashings you can see from the ground are cosmetic or structural. Given the city’s mix of 1950s built-up roofs, 1970s shingle tract homes, and newer tile subdivisions, inspection findings vary wildly block to block, and guessing wrong means paying for repairs you didn’t need or skipping ones you did. Van Nuys Roofing Co offers Roof Inspection as a standalone service, no repair purchase required, so you get an honest condition assessment before committing to any spend.
Roof Inspection Services
Signs you need it
You see cracked tile edges, lifting shingle tabs, rusted flashing, or water stains on ceilings after rain, and you want to know what’s actually failing before it gets worse.
What it costs in Ontario
A standard visual roof inspection on an Ontario home typically runs $180 to $260.
How we do it
We walk the roof, document every crack, lifted tab, and flashing gap with photos, check attic-side for moisture and ventilation, then sit down with you to review findings and a prioritized repair list.
Hail Damage Roof
Signs you need it
After a hailstorm rolls through Ontario, you notice dents in roof vents, granule loss in gutters, or circular impact marks on shingle surfaces from the ground.
What it costs in Ontario
A hail-specific inspection on an Ontario home typically runs $200 to $320, depending on roof size and accessibility.
How we do it
We map impact points across each slope, test for granule loss and hidden shingle fractures, document everything for your insurer, and give you a straight answer on whether you have a claim worth filing.
Roof Estimate
Signs you need it
You’re weighing repair versus replacement, or you want a written, itemized number before making any financial decision on your Ontario roof.
What it costs in Ontario
A roof replacement estimate in Ontario is free, while a standalone inspection estimate with full documentation runs $180 to $260.
How we do it
We measure every plane, note the material, pitch, and existing underlayment, run the numbers across multiple brand options, and give you a written line-item quote with no change orders down the line.
Free Roof Inspection
Signs you need it
You’re not sure if anything is wrong and don’t want to pay for a full documented inspection, but you’d like a professional set of eyes on your Ontario roof.
What it costs in Ontario
We offer free roof inspections for Ontario homeowners in specific situations, such as after major wind events, while our full documented inspections run $180 to $260.
How we do it
We walk the roof, flag any urgent issues, and tell you honestly whether a full documented inspection is worth the cost or whether your roof is in acceptable shape as-is.
Roof Inspection Companies
Signs you need it
You’ve been burned by a roofer who pushed a replacement before even looking, and you want a company that treats inspection as a real service, not a sales appointment.
What it costs in Ontario
A documented inspection from a multi-brand roofing company in Ontario typically runs $180 to $340.
How we do it
We inspect first, recommend second, and since we work with seven material brands rather than one, our recommendation is based on your roof’s actual condition, not on what we’re incentivized to sell.

Do I need a roof inspection before selling a home in Ontario?
Ontario buyers increasingly ask for roof condition reports before closing, especially on 1940s through 1970s homes with original sheathing. A $180 to $260 inspection now can prevent a negotiation surprise later. Call (866) 321-6172 to book one.
Brands We Service in Ontario
We work with GAF, CertainTeed, Owens Corning, and Boral, among seven leading roofing material manufacturers. That means one crew knows the installation specs, warranty requirements, and failure patterns for each product line, and we stock parts locally for the brands most common on Ontario roofs. Product availability and turnaround vary by brand, so see our brands for what we carry and what’s orderable with reasonable lead times.

What Ontario Customers Say
"Added a ridge vent and cleared the blocked soffit vents. Attic temperature in the summer dropped noticeably and the upstairs is livable now."
— Daniela Delgado"Full replacement after the hail. They handled the insurance adjuster meeting, documented everything, and I did not have to argue with anybody. Crew was here three days and the yard was cleaner when they left than when they started."
— Maya Shah"Quality work on the repair. There were a few nails left in the driveway that the magnet missed, so check yours before driving over it. Otherwise no complaints."
