Roofers in Ontario, CA
Roof inspection in Ontario starts with understanding what the Santa Ana winds do to a roof over a decade. Most Ontario homes carry concrete tile or aging asphalt shingles that look fine from the ground but have failing underlayment, loose ridge caps, or dried-out flashing hidden underneath. Ridgeway Roof Repair has served Ontario since 2018, and we’ve learned that the roof that gets inspected before October is the one that still has all its tile after the first wind advisory. Call (877) 588-7942 when you want to know what your roof is actually dealing with.
Why Ontario Homes Are Different
Ontario’s roofing work is defined by the Santa Ana wind corridor. This is the city where dry, 40-60 mph desert winds blast down the Cajon Pass and funnel through the Inland Empire, ripping ridge caps, lifting tile, and peeling aging shingles off homes that never see a hurricane. Roofers here build for wind uplift and thermal cycling, not rain – an inverted priority compared to coastal or northern California cities.
The housing stock follows the city’s growth. Ontario’s core – the 91761, 91762, and 91764 ZIP codes – is dominated by post-WWII and 1950s-70s tract housing. These are low-pitch gable roofs with concrete or clay tile, plus older asphalt shingle roofs now reaching end of life. The north side, including the 91758 area, has newer master-planned subdivisions with tile and composite underlayments that still fail at flashings and valleys. Different era, different failure points, same wind.
The climate compounds everything. Ontario sits in the semi-arid Inland Empire with 100°F+ summers and intense UV. Tile underlayment bakes and cracks. Daily thermal expansion and contraction works shingles and flashing loose long before rain ever tests them. Winter rains then find those weakened seams. It means a roof in Ontario can fail from sun damage alone, even in a dry year.
Styles & brands we work with
Our Main Ontario Services
Most Ontario homeowners call us for one of two things: a repair that needs to happen before the next wind event, or a full replacement that’s been put off for too long. Here’s what each involves in Ontario.
Roof Repair in Ontario
Repair work in Ontario is rarely about a single missing shingle. We’re usually called after a Santa Ana event has lifted tile on the north and east slopes, torn a ridge cap loose, or exposed underlayment that’s been baking in the sun for 20 years. The repair is often structural – re-securing what the wind loosened before rain finds the gap. We work across competing brands, so if your roof carries GAF shingles or Boral tile, we replace with what belongs there, not what’s on the truck. See Roof Repair in Ontario for the full scope of what we handle.
Roof Replacement in Ontario
Replacement in Ontario means choosing materials that survive this specific climate. Concrete tile handles the UV well but needs new underlayment every 20-25 years. Asphalt shingles fail faster here than in coastal cities because the heat breaks down the asphalt binder. We walk through GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral options and recommend the one that fits your roof’s pitch, exposure, and budget. Start with Roof Replacement in Ontario for what to expect from tear-off to final inspection.

Roof Inspection in Ontario
A roof inspection in Ontario answers the question homeowners ask us most: is my roof ready for the next Santa Ana season? Given that most of Ontario’s housing stock dates to the 1950s through 1970s, and given what 100°F summers do to underlayment and flashing, a structured inspection is the difference between catching a $600 repair and financing an $18,000 replacement. That’s the point of our Roof Inspection service – it’s a standalone assessment, not a sales pitch wearing a hard hat.
What makes inspections different here is timing. The Santa Ana wind events run fall through winter, and they hit north and east-facing slopes first. Ontario roofers get their emergency calls after the first advisory, but the smart inspection happens before it. We pre-check ridge and hip fastening, because that’s what the wind takes first.
Roof Inspection Services
Signs you need it
If your roof is over 15 years old, you’ve noticed tile fragments in the yard after a windy night, or you saw water stains on the ceiling after the last winter rain, you’re overdue.
What it costs in Ontario
A full visual and structural roof inspection in Ontario typically runs $150 – $350, and the price is quoted before we arrive.
How we do it
We walk the entire roof surface, document every finding with photos, check flashing, underlayment visibility, ridge caps, valley integrity, and drainage, then deliver a written report with recommended priorities.
Hail Damage Roof
Signs you need it
Hail is less common in Ontario than wind, but when it does hit, it leaves circular impact marks on tile, bruised shingle granules, and cracked ridge caps that look cosmetic but shorten roof life.
What it costs in Ontario
A hail-specific assessment after a storm is part of our inspection service and falls in the same $150 – $350 range depending on roof size and access.
How we do it
We inspect impact points on the most exposed slopes, check for granule loss in gutters, photograph all damage for insurance documentation, and give you a straight repair recommendation.
Roof Estimate
Signs you need it
When you already know the roof needs work and you want a written number for repair or replacement, not a broad inspection.
What it costs in Ontario
Estimates are free in Ontario when they’re part of a repair or replacement scope, so you’re not paying just to get a price.
How we do it
We measure the roof, assess the current materials and condition, walk you through what needs to change, and write a line-item estimate you can compare against other Ontario roofers honestly.
Free Roof Inspection
Signs you need it
If you’re a new Ontario homeowner and you don’t know the roof’s history, or you’re selling and need to understand what a buyer’s inspector will find.
What it costs in Ontario
For simple visual checks tied to a potential repair or replacement job, we offer a free roof inspection; full documented assessments with photo reports are $150 – $350.
How we do it
We do a ground-level and ladder-accessible walk, check for obvious wind damage, missing fasteners, lifted flashing, and give you an honest read on whether the roof warrants a deeper look.
Roof Inspection Companies
Signs you need it
When you’ve had a quote from a general contractor and want a roofing-only specialist’s independent assessment before you commit.
What it costs in Ontario
Independent inspection reports from factoring in equipment and access time, a detailed assessment from a roofing-only company in Ontario runs $150 – $350.
How we do it
Because we only do roofing, our inspection isn’t a loss leader for some other trade; we look at your roof as the only thing that matters and report accordingly.
What Roof Inspection Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Visual roof inspection (ladder-accessible) | $150 – $200 |
| Full documented inspection with photo report | $200 – $350 |
| Hail or wind damage assessment (post-storm) | $150 – $350 |
How long does a roof inspection take in Ontario?
Most Ontario inspections take 45 minutes to 90 minutes depending on roof size, accessibility, and how many slopes need documentation. We schedule around wind advisories so we’re not on your roof during unsafe gusts. Call (877) 588-7942 to book a time.
Can you inspect a tile roof without walking on it?
Most of the time, yes. We can assess concrete and clay tile from the eaves and ladder line, which protects the tiles from breakage during inspection. If we need to access a specific valley or flashing, we use roof boards to distribute weight.
Brands We Service in Ontario
We work across seven roofing manufacturers so the material matches the roof, not our inventory. In Ontario, that means we commonly service and install GAF, CertainTeed, and Owens Corning asphalt shingles, plus Boral tile when the home calls for it. Parts for major brands are stocked locally, so turnaround on repairs doesn’t wait on a distributor. See our brands for the full lineup.

FAQs About Roofers in Ontario

What Ontario Customers Say
"Roof is solid and the price was competitive. The job ran a day over because of weather, which is nobody's fault, but I would have liked a call about it rather than noticing the crew hadn't shown up."
— Andres Torres"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."
— Maria Morales"Tile roof, three cracked tiles and a slipped one. Matched the tile, no color mismatch, and it took him half a day."
— Marcy Barrett
