Roofers in Ontario, CA
Roof Inspection is where most Ontario homeowners start, and for good reason. The city’s mix of 1950s tract homes and 1990s stucco subdivisions means roof conditions vary wildly from street to street, and the Inland Empire’s heat and Santa Ana winds create failure patterns you won’t find closer to the coast. Hollywood Roofing Co has served Ontario since 2016, and our inspectors know exactly what to look for on a north-side Ontario roof before small wind damage becomes a ceiling leak. Call (833) 589-7971 to schedule a roof inspection, repair, or replacement quote.
Why Ontario Homes Are Different
Ontario sits at the base of the Cajon Pass, right in the Inland Empire’s wind corridor. When Santa Ana events blow through, the gusts funnel into the Cucamonga and Etiwanda areas and hit the north side of the city hard. We routinely see sheared-off ridge caps, lifted shingle tabs, and patio covers torn loose after a strong wind event. That’s a different failure mode than most of Southern California deals with. Freeze-thaw isn’t the concern here. Wind uplift is.
The housing stock compounds it. Central Ontario neighborhoods in 91761, 91762, and 91764 are full of mid-century single-story homes with shallow-pitch roofs and original builder-grade shingles now well past their service life. The north and east growth areas have 1990s-2000s two-story stucco homes with concrete tile and dimensional shingles, but many of those are hitting the 20-25 year mark too. Add hundred-degree summer days that bake sealant and flashing, and you get a city where roof condition varies dramatically from one block to the next.
Attached patios, garages, and flat-section additions are common throughout Ontario. Those transition points and flashing details are where leaks start, and they’re where a generic roof company gets it wrong. Wind-rated fastening and proper ridge ventilation matter more in Ontario than almost anywhere else in the region.
Styles & brands we work with
Our Main Ontario Services
Most Ontario homeowners call us for one of two things: a roof that’s showing wind or heat damage and needs repair, or a roof that’s simply reached the end of its useful life. Here’s what each looks like in this city.
Roof Repair in Ontario
Repairs in Ontario are usually wind-driven. A Santa Ana event rolls through, and suddenly there’s a lifted shingle tab on the windward slope or a ridge cap sitting in the yard. We also handle heat-related failures: dried-out sealant around vents and flashing, granule loss that’s left shingles brittle, and cracked tiles on low-slope sections. Repairs here are about matching the existing roof correctly, whether it’s 1950s comp shingle or 2000s concrete tile. See our Roof Repair in Ontario page for full details and pricing.
Roof Replacement in Ontario
A full replacement in Ontario means choosing materials that can handle sustained heat and sudden wind. Many original roofs in the central neighborhoods are at or past their service life, and the right replacement often involves upgrading fastening patterns and ventilation rather than simply tearing off and nailing down the same product. We install across seven major brands, so the recommendation is matched to your home and budget, not to what we happen to stock in the yard. Visit our Roof Replacement in Ontario page for material options and full pricing.

Roof Inspection in Ontario
Ontario’s older housing stock and brutal summer heat mean a roofer’s eyes catch failures years before they show up indoors. An Roof Inspection from Hollywood Roofing Co gives you a straight answer on what your roof needs and what it can wait on. We inspect with the local failure patterns in mind: wind-lifted edges on north-facing slopes, heat-cracked flashing, and granule loss from UV exposure that’s common across 91761, 91762, and 91764.
Roof Inspection Services
Signs you need it
You’re seeing granules in the gutters, noticing lifted shingle tabs after a Santa Ana event, or your roof is over 15 years old in Ontario’s heat and you want a baseline before the next rainy season.
What it costs in Ontario
Roof inspection in Ontario typically runs $199 – $350 depending on roof size, pitch, and whether it’s a single story or two-story home like many in the north and east subdivisions.
How we do it
We walk the entire roof surface, document condition with photos, check flashing and vent seals, inspect the attic for ventilation and moisture issues, and deliver a written report with prioritized recommendations and clear pricing for anything that needs attention.
Roof Estimate
Signs you need it
You know the roof needs work, and you want a line-item price before you make a five-figure decision.
What it costs in Ontario
Roof estimates are free in Ontario whenever they’re part of a planned repair or replacement project.
How we do it
We measure the roof, assess decking and underlayment condition from the attic and roof surface, review material options across the seven brands we install, and provide a written quote with no change orders or surprises later.
Hail Damage Roof
Signs you need it
After a hailstorm, you see dents in vents or flashing, dark spots on shingles where granules were knocked off, or you’ve noticed your neighbors filing claims.
What it costs in Ontario
Hail damage assessments in Ontario are included with your inspection if hail is the suspected culprit, and the full inspection runs $199 – $350.
How we do it
We look for the specific hail signature on each material type, document everything for your insurance claim, and provide a repair scope that matches what your policy will actually cover.
Free Roof Inspection
Signs you need it
You want to know the honest condition of your roof before deciding whether repair or replacement is the next move, without paying upfront for a sales pitch.
Inspection costs in Ontario vary, but when you’re planning a repair or replacement with us, we’ll credit the inspection fee toward the work.

Roof Inspection Companies
Signs you need it
You’re comparing a few Ontario roofers and want to know what separates one inspection from another before you commit.
What it costs in Ontario
Inspections from reputable Ontario roofing companies carry a similarly modest fee, typically $199-$350, unless they’re waiving it to lock in a bigger job.
How we do it
We are one of the few companies that offers inspection as a standalone, dedicated service rather than as a disguised sales appointment, and our report is yours to keep and act on at your own pace.
What Roof Inspection Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Full roof inspection (no repair needed) | $199 – $350 |
| Inspection with hail damage documentation | $199 – $350 (included with inspection) |

How long does a roof inspection take in Ontario?
Most Ontario inspections run one to two hours. Larger two-story homes in the north and east growth areas and older homes with multiple roof sections and additions take the longer end of that range. The written report follows within 24 hours.
Will an inspection tell me if I need repairs or replacement?
Yes. You’ll get a prioritized list of what needs attention now, what’s going to need attention within a year or two, and what’s fine. The report includes clear pricing so you can decide on your own timeline. Call (833) 589-7971 to schedule.
Brands We Service in Ontario
We install and service GAF, CertainTeed, Tamko, and Boral systems throughout Ontario, with parts and matching materials available for most repair calls the same week. That breadth means when you need a repair on an existing roof, we can often match the exact shingle or tile rather than asking you to accept a close-enough patch. See our brands for the full lineup.

In Ontario, prices climb with two factors: roof pitch and the number of transitions. Homes with attached patios, garages, and flat-section additions need more flashing work, and that’s honest labor and material cost. You’ll get an upfront line-item quote before we start, and that number doesn’t move unless we uncover something structural that nobody could have seen from the surface.

FAQs About Roofers in Ontario
Yes, the City of Ontario generally requires permits for roof replacement and for repairs that involve structural changes or decking replacement. Minor repairs like shingle or flashing replacement typically don’t require one. We handle the permit paperwork on any job that needs it, and inspections are scheduled as part of the scope.
During the fall and winter wind season, we prioritize calls from Ontario homeowners with active leaks or exposed decking. That usually means we’re on the roof within a few days. Non-emergency wind damage can be scheduled within the same week. Call (833) 589-7971 and we’ll give you an honest arrival window.
Yes. Many of the 1990s-2000s communities in north and east Ontario have HOA requirements around roof material and color. We’ll review your HOA’s guidelines before recommending materials, and we install systems that meet those standards without compromising on wind resistance or heat performance.
When you’re ready to know exactly what your Ontario roof needs, call (833) 589-7971 to schedule your free estimate. We’ll walk the roof, give you a straight answer, and put pricing in writing before you decide anything.

What Ontario Customers Say
"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."
— Doug Ziegler"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."
— Norma Rodriguez"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."
— Darius Prince
