Roofers in Ontario, CA
In Ontario, roof inspections catch the problem before the next Santa Ana wind turns a loose shingle into a leak. Most homes here were built between the 1950s and 1980s, and their original or first-replacement asphalt shingle roofs are either mid-life or past it. We focus on heat damage, wind lift, and the kind of granule loss that comes from years of 100°F summers. Call Orange County Roofing Co at (866) 942-4187 when you want a straight read on your roof, not a sales pitch.
Why Ontario Homes Are Different
Ontario sits in the hot, dry Inland Empire, and the difference shows up in roofing within a decade. Summer temperatures routinely exceed 100°F, and the UV intensity doesn’t just age shingles. It bakes the oils out of asphalt composition material, causing granule loss and cracking far earlier than you’d see in coastal cities. Then come the Santa Ana winds, which blow downslope through the Cajon Pass from October through March. Gusts hit the foothill neighborhoods north of the 210 and along the 10 corridor hard, lifting edges and peeling ridge caps before field shingles even show damage. We inspect those areas first because that’s where failures start.
Much of the housing stock is 1950s to 1980s tract homes across ZIPs 91761, 91762, and 91764. These roofs were built for a milder era, and many have low-slope or flat sections over additions and patios that trap heat differently than the main roof deck. The east side of Ontario, especially newer developments in 91761 and 91764, features tile and Spanish-style roofs that need different underlayment, flashing, and fastener approaches. Ontario’s intermittent winter rains expose the leaks that months of dry heat hide, which is why a roof inspection here needs to account for every season, not just the most recent one.
Styles & brands we work with
Our Main Ontario Services
Most Ontario homeowners call us for one of two reasons: a specific problem after wind or rain, or a full replacement they know is coming. Here’s how each works in this city.
Roof Repair in Ontario
Repair work in Ontario usually means wind damage along ridge lines, sun-seared shingles, or leaks around the flat sections over older additions. We match the existing material and color, address the flashing, and tell you honestly whether the repair buys you five years or five months. After a Santa Ana event, we check starter strips and ridge caps first, because those fail before the field shingles do. For details on repair scope and timing, see Roof Repair in Ontario.
Roof Replacement in Ontario
A full replacement here isn’t just about tearing off old shingles. It’s about choosing material that survives Inland Empire heat and wind loads, deciding whether the underlayment on those low-slope sections needs to be rebuilt, and making sure the ridge caps and starter strips can handle the next blow. We carry seven major brands, so the recommendation comes from your roof’s needs, not our inventory. For a breakdown of what replacement involves in Ontario, see Roof Replacement in Ontario.

Roof Inspection in Ontario
Roof inspection in Ontario tells you what your roof will do next summer and next Santa Ana season, not just what it looks like today. Homes built between the 1950s and 1980s in ZIPs 91761, 91762, and 91764 are hitting the age where granule loss, edge lift, and flashing decay show up together. A standalone Roof Inspection gives you a diagnostic report you can act on when you’re ready, whether that means filing an insurance claim, budgeting for next year, or deciding a repair is all you need.
Roof Inspection Services
Signs you need it
Granules collecting in your gutters, shingles that look shiny or cracked from the street, and lifted edges after a wind event are the three most common signals we see across Ontario.
What it costs in Ontario
A visual roof inspection in Ontario typically runs $150 to $325, depending on roof size, slope, and access.
How we do it
We walk the roof, check flashing and penetrations, inspect the attic for moisture, and document every finding with photos and a report you keep.
Roof Estimate
Signs you need it
When your inspection shows enough damage that you need real numbers on repair versus replacement, an estimate gives you the line-item comparison.
What it costs in Ontario
We provide detailed, itemized estimates as part of our standard inspection and quoting process, so you can compare scope and price side by side.
How we do it
We measure the roof, calculate material quantities from our seven brand options, and price labor, disposal, and any structural repairs separately so nothing is hidden.
Hail Damage Roof
Signs you need it
After a hail event in Ontario, you may see circular dents in shingles, displaced granules, or small cracks that collect water.
What it costs in Ontario
Hail damage inspections in Ontario are included in our standard visual inspection fee of $150 to $325, and the report you receive supports your insurance claim.
How we do it
We document each damaged area with dated photos, mark the affected slope, and give you a claim-ready summary that explains the extent and likely repair cost.
Free Roof Inspection
Signs you need it
If you’re buying or selling a home in Ontario and need a clear read on roof condition without committing to a repair contract, a free or low-cost inspection baseline helps you negotiate.
What it costs in Ontario
We offer free roof inspections as part of larger replacement quotes, while standalone diagnostic inspections are priced at $150 to $325.
How we do it
We assess the roof, walk you through what we find with photos and a plain-language summary, and give you the number only if you ask for a quote.
Roof Inspection Companies
Signs you need it
You want a company that treats inspection as its own service, not a sales call disguised as one.
What it costs in Ontario
Standalone inspections in Ontario from specialized roofing companies like ours run $150 to $325 depending on roof complexity.
How we do it
We inspect, document, and recommend, with no obligation to buy anything, and you keep the report whether you hire us or not.
What Roof Inspection Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Visual roof inspection (standalone) | $150 – $325 |
| Inspection with written report for insurance | $200 – $325 |
| Inspection plus repair estimate | Included with quote |
Prices shift with roof size, slope, and how many stories we’re working on. A two-story home with a steep pitch and multiple additions in Ontario takes longer to inspect safely than a single-story ranch.
How long does a roof inspection take in Ontario?
Most Ontario roof inspections take 45 to 90 minutes depending on roof size, slope, and access. We schedule them during daylight hours when granule loss and flashing defects are easiest to see. Call (866) 942-4187 to book.
Will an inspection tell me if I need repair or replacement?
Yes. Our report separates what needs attention now from what can wait, and it includes life-expectancy estimates for each roof section. Call (866) 942-4187 for a straight answer.
Brands We Service in Ontario
We install Tamko, Boral, GAF, and CertainTeed, among others, and our Ontario material runs match what local homes actually need: heat-resistant asphalt shingles and tile-compatible underlayment for Spanish-style roofs. Seven brands means you choose based on budget, warranty tier, and look, not what a single supplier wants to move. That’s the edge of the our brands lineup.

FAQs About Roofers in Ontario
Yes, the City of Ontario requires a building permit for roof replacement, and we handle the permit application, inspection scheduling, and final sign-off as part of the job. Repairs that don’t alter the roof structure usually don’t need one. We pull permits and pass inspections before we call the job done.
We schedule Santa Ana damage inspections on a priority basis and work through Ontario foothill neighborhoods first, since that’s where gust damage concentrates. A standard roof inspection is typically available within a few business days. Call (866) 942-4187 with your address and we’ll give you a straight answer.
Yes, we cover 91758, 91761, 91762, and 91764, which includes both the older tract home neighborhoods and the newer east-side developments. Our crews are familiar with the HOA requirements in some of Ontario’s planned communities, and we’ll confirm any design-review rules before material is ordered.

What Ontario Customers Say
"He told me my roof had another five or six years in it and I should not replace it yet. He was standing there with a quote pad in his hand. That's why I'll call him when it's time."
— Carmen Castillo"Leak over the kitchen turned out to be a cracked boot around a vent pipe, not the roof itself. He showed me the photo from up there and replaced the boot for a couple hundred dollars. The company before him had quoted a full tear off."
— Sofia Hernandez"Went up in the attic first with a flashlight before going on the roof, which no other estimator bothered to do. Found the stain and worked backward from there."
— Marcus Bryant
