Roofers in Ontario, CA
Roof inspection in Ontario starts with understanding what the Inland Empire actually does to a roof. The homes here, mostly mid-century tract builds with low-pitch asphalt shingle roofs, sit in a heat-and-wind corridor at the base of the Cajon Pass. That means shingles bake under 100°F summer sun and then get hit by Santa Ana gusts that peel ridge caps and hip shingles on windward slopes. Baycrest Roofing has served Ontario since 2013, and our inspection-led process means you find out what your roof actually needs before anyone quotes a dollar figure. Call (866) 412-5697 to schedule yours.
Why Ontario Homes Are Different
Ontario’s roofing challenges are not the same as coastal Los Angeles. The city sits directly in the path of air that funnels through the Cajon Pass, and when Santa Ana winds hit, they hit hardest on the east side. We regularly see subdivisions built in the 1960s and 70s with lighter nailing patterns that simply don’t hold up to those gusts. After a wind event, whole rows of ridge caps and hip shingles get peeled back on windward-facing slopes, while the leeward side looks untouched.
Then there’s the heat. Summer temperatures in Ontario routinely pass 100°F, and the UV load ages asphalt shingles faster than any coastal climate. Sealant dries out, granules loosen, and fasteners fatigue from the constant thermal expansion and contraction. By the time winter rain arrives, any wind-loosened flashing or lifted shingle becomes an active leak path. Homes near the historic downtown core, many built in the post-war years, are now decades past the service life of their original decking. Even newer tracts in the 91762 and 91764 ZIP codes deal with the same dual stress: thermal bake in summer, wind uplift the rest of the year.
What this means for homeowners is simple. A roof that looks fine from the street may have hidden fastener fatigue or granule loss that only shows up during an inspection. Baycrest’s approach is to inspect first, recommend second. We match the material to your roof, not your roof to our inventory.
Styles & brands we work with
Our Main Ontario Services
Most Ontario homeowners call us for one of two reasons: a roof that’s showing damage after a wind event or a roof that’s aged past the point where patchwork makes sense. Both start with the same first step, an honest inspection.
Roof Repair in Ontario
Ontario’s wind corridor creates a specific repair pattern we see after every major Santa Ana event: lifted ridge caps, torn flashing at roof-to-wall transitions, and shingle rows peeled back on east-facing slopes. Repair in Ontario is often the right call when the damage is localized and the rest of the roof still has years of life left. We tell homeowners the truth, repair when repair is honest, replace when replacement is necessary. No upsell, no pressure. See our full breakdown at Roof Repair in Ontario.
Roof Replacement in Ontario
When an Ontario roof reaches the end of its service life, usually after 20-plus years of Inland Empire heat, replacement is the honest recommendation. The mid-century tract homes throughout Ontario, from the 91761 ZIP to the newer subdivisions further east, were built with materials and nailing patterns that weren’t designed for today’s pass-driven winds. A full replacement lets us correct those issues: better underlayment, upgraded fastening, and shingles rated for high UV. We carry GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so material choice follows your roof’s needs and your budget, not a dealer quota. Read more at Roof Replacement in Ontario.

Roof Inspection in Ontario
A roof inspection in Ontario is the diagnostic step that tells you whether you need a repair, a replacement, or neither. Given the city’s mix of aging 1960s-80s tract roofs and the extreme thermal cycling from Inland Empire summers, an inspection here often catches problems that haven’t leaked yet but will within a year or two. Baycrest’s inspection-led process, the same one we use across our Roof Inspection service, means you never pay for more work than your roof actually requires.
Roof Inspection Services
Signs you need it
Granules collecting in gutters, shingles that look shiny or bald in patches, or any visible lifting along ridge lines after a Santa Ana wind event are all signs an inspection is overdue.
What it costs in Ontario
A standard roof inspection in Ontario runs $200 to $550, depending on roof size, pitch, and whether it includes drone or infrared imaging.
How we do it
We walk the roof surface, check flashing at penetrations and transitions, examine the attic for decking stains or ventilation issues, and document every finding with photos so you see exactly what we see.
Hail Damage Roof
Signs you need it
Dented flashing, soft spots you can feel underfoot, or circular impact marks on shingles after a spring storm point to hail damage that shortens roof life even when it doesn’t leak immediately.
What it costs in Ontario
Hail-specific roof inspections in Ontario typically fall in the $250 to $450 range and include documentation you can use for an insurance claim.
How we do it
We assess impact patterns across all slopes, check gutters and soft metals for dents, measure granule loss, and note which slopes meet the hail-size thresholds insurers require.
Roof Estimate
Signs you need it
You need a roof estimate when you’re planning a sale, comparing repair versus replacement costs, or responding to an insurance adjuster’s initial assessment.
What it costs in Ontario
Most Baycrest roof estimates in Ontario are free when you’re comparing repair or replacement options, with written line-item pricing delivered after the inspection.
How we do it
We inspect first, then build the estimate around what the roof actually needs, specifying material lines like GAF or Tamko by name so you know exactly what you’re paying for.
Free Roof Inspection
Signs you need it
You haven’t had a professional look at the roof since buying the home, or you want a second opinion before committing to work another contractor quoted.
What it costs in Ontario
Baycrest offers free roof inspections in Ontario when tied to an actual repair or replacement decision, with no charge for the assessment itself.
How we do it
We treat the free inspection the same as a paid one: full roof surface assessment, attic check, and photo documentation, followed by an honest recommendation with zero obligation.
What Roof Inspection Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Standard roof inspection | $200 – $550 |
| Hail damage inspection | $250 – $450 |
| Inspection with drone imaging | $300 – $600 |
Prices in Ontario shift based on roof size and complexity. A sprawling single-story rancher in the 91761 ZIP takes less time than a two-story with steep pitch and multiple valleys. Steep slopes, multi-level rooflines, and the extent of prior repairs can all push a quote toward the higher end. But you’ll see the full number before any work starts, with no change orders added later.
How long does a roof inspection take in Ontario?
Most Ontario roof inspections take 45 to 90 minutes on site. Larger two-story homes or roofs with complex valley systems run longer. You’ll have photos and a written summary the same day.
Do you inspect roofs before a home sale in Ontario?
Yes. Pre-sale roof inspections are common in Ontario, especially for the mid-century tract homes where buyers and their lenders want roof condition documented before closing. Call (866) 412-5697 to schedule one.
Brands We Service in Ontario
Baycrest is authorized to install products from seven major shingle manufacturers, which means your Ontario roof gets the material that fits it, not the one we’re incentivized to push. For the heat-and-wind conditions in Ontario, we often recommend Atlas for its wind-rated shingle lines, Tamko for budget-conscious replacements on rental tracts, and GAF when you want the premium architectural line. See our full our brands page for the complete list and warranty details.

Two factors push Ontario roofing prices up more than anything else. The first is decking damage, common in older post-war homes near the downtown core where roof sheathing has seen six decades of thermal cycling. The second is access: two-story tract homes with steep pitches and tight side yards cost more in labor hours than simple one-story ranchers. Baycrest’s upfront-price promise means you receive line-item pricing after inspection, and that number doesn’t change once work starts unless you approve a scope change in writing.
Neighborhoods We Serve in Ontario
Baycrest services roofs across all four Ontario ZIP codes, from the older post-war blocks near the historic downtown core to the sprawling 1970s tracts along the 60 freeway corridor and the newer subdivisions pushing east toward the 15. We know which neighborhoods show wind damage first after a Cajon Pass event and which ones bake hardest in summer.
- Downtown Ontario historic district
- South Ontario near the 60 freeway
- East Ontario tracts toward the 15
- North Ontario off Vineyard Avenue
- West Ontario bordering Montclair and Upland
Response time across Ontario is typically one to two business days for inspections, with same-week scheduling available most of the year. Wind event damage calls get triaged first, since exposed decking can’t wait through a rain forecast.

What Ontario Customers Say
"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."
— Ebony Nash"Valley had been done without proper underlayment and was leaking. Redone correctly, and he explained exactly what had been wrong so I could understand it."
— Emily Novak"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."
— Marisol Morales
