Roofers in Ontario, CA
Roof inspection in Ontario is the smart first move for most homeowners here, and it’s a service we’ve performed across 91761, 91762, and 91764 more times than we can count. The inland heat, Santa Ana winds, and sudden monsoon downpours don’t damage roofs the way coastal weather does – they do it faster, drier, and in ways that are easy to miss until water shows up on your ceiling. If your roof is more than 12 years old or took a hit during the last wind event, call (866) 217-3967 to get eyes on it before a small crack becomes a big problem.
Why Ontario Homes Are Different
Ontario sits east of the pass where the Inland Empire opens up, and the roofing conditions here are genuinely different from what you’d see in Los Angeles or Orange County. Summer heat holds at 100°F or higher for days at a stretch, cooking asphalt shingles until they turn brittle and crack along the granule lines. Santa Ana winds hit twice a year, lifting tile edges and pulling flashing loose on stucco tract homes in 91761 and 91762. Then the monsoon thunderstorms roll through in late summer and dump enough water in 40 minutes to expose every dried-out underlayment seam and failed pipe boot on the roof.
The housing stock compounds it. Ontario is full of mid-century tracts and 1960s-80s stucco houses – homes that were built well but are now 40 to 70 years old. Many have original concrete tile roofs that look fine from the street while the underlayment underneath has turned to dust. Around 91762, after a Santa Ana event, we regularly find cracked ridge tiles and lifted hip caps that let water channel straight into the wood framing. Meanwhile, the warehouse and logistics corridor along 91761 and 91764 is a flat-roof world – TPO and modified bitumen systems that need a different skillset entirely. A roofing company that only does shingles can’t help those buildings, which is why we carry materials and training for both residential and low-slope commercial work.

Our Main Ontario Services
Most homeowners in Ontario call us for one of two reasons: something is leaking or the roof has hit the end of its useful life. Here’s how each plays out in this city.
Roof Repair in Ontario
Repairs in Ontario are usually driven by the same three culprits: wind-lifted flashing, dried-out pipe collars, and cracked or slipped tiles. On the older stucco homes in 91761, we shift a lot of ridge tiles back into place and reseal the mortar beneath. On asphalt shingle roofs, Ontario’s UV exposure creates a distinct failure pattern – granule loss first, then hairline cracks, then open splits that leak during the first hard monsoon rain. The goal is always to extend the life of what’s there when it makes sense, not sell a replacement prematurely. See how we scope repair work on our Roof Repair in Ontario page.
Roof Replacement in Ontario
When a roof in Ontario has lost its underlayment, or the shingles have torn and curled across multiple slopes, replacement is the honest call. The material you choose matters more here than it does on the coast – Ontario’s heat cycles demand products rated for high thermal movement, and Boral tile and CertainTeed shingles both hold up differently under this kind of exposure. We install materials from seven manufacturers, so the recommendation you get is based on your roofline, your budget, and how long you plan to stay in the home.

Roof Inspection in Ontario
A professional roof inspection in Ontario is the difference between catching a $400 pipe boot failure and paying $2,400 to fix the ceiling, the drywall, and the rotted sheathing after monsoon season. We offer Roof Inspection as a standalone service because we think you should know exactly what your roof needs before anyone asks you to spend money on repairs or replacement. Ontario’s climate creates specific, predictable failure points – dried underlayment on the older tile homes, UV-embrittled shingles on the tract houses, and loose flashing everywhere after Santa Ana season. A trained inspector who works in this city knows where to look first.
Roof Inspection Services
Signs you need it
You should schedule an inspection if your roof is over 12 years old, you saw granule buildup in the gutters after the last rain, you noticed daylight coming through the attic, or a Santa Ana event stripped tiles or shingles off the slope.
What it costs in Ontario
A documented inspection with photos and a repair-or-replace recommendation typically falls in the $175 – $400 range in Ontario, depending on roof size, access, and whether it’s a single-family home or a larger flat-roof structure.
How we do it
We walk the entire roof surface, check every flashing point, pipe boot, valley, and ridge line, inspect the underlayment at the eaves where it’s visible, then go into the attic to look for water staining, then hand you a written assessment with photos and a straight answer.
Hail Damage Roof
Signs you need it
After any hailstorm in Ontario, look for impact marks on soft metal flashing, spatter patterns on shingles where granules have been knocked off, and scattered debris on the ground – all indicators that a professional damage assessment is warranted.
What it costs in Ontario
We scope hail inspections within the standard $175 – $400 Ontario inspection range, and if a claim is warranted we document everything the adjuster needs to see.
How we do it
We photograph the hail strike marks, map the affected slopes, inspect the flashing and vents for denting, then compile a dated report you can hand directly to your insurance carrier or use to get a repair estimate.
Roof Estimate
Signs you need it
You need a formal estimate when you know you’re repairing or replacing and you want line-item pricing so you can compare options without a sales pitch attached.
What it costs in Ontario
Most roof estimates in Ontario fall within the $175 – $400 range when paired with an inspection, and we apply that fee toward the work if you move forward with us.
How we do it
We measure the roof by hand, calculate material quantities across the brands that fit your budget, and produce a written, fixed-price estimate so there are no change orders after work starts.
What Roof Inspection Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Standalone roof inspection (single-family home) | $175 – $400 |
| Inspection with written photo report | $200 – $400 |
| Hail or storm damage assessment | $175 – $400 |
The spread comes down to roof size, access difficulty, and whether the structure has multiple stories or a steep pitch. We charge a flat fee, never by the hour.
How long does a roof inspection take in Ontario?
Most single-family inspections in Ontario take 60 to 90 minutes on site. You’ll get the written report and photos the same day, and the estimate, if you need one, comes back within another day.
Do I need an inspection before filing an insurance claim?
You should have documentation for any insurance claim. Our inspection report includes dated photos and a damage map, which gives you evidence to present to your adjuster. Call (866) 217-3967 to schedule it.
Brands We Service in Ontario
We install and supply materials from GAF, CertainTeed, Owens Corning, and Boral – four manufacturers with very different strengths in Ontario’s climate. We keep common shingle colors, underlayment rolls, flashing, and sealants in our local supply chain, which means most repair jobs start within a few days of the estimate, not weeks. See the full material lineup on our brands page.

| Roof inspection (standalone) | $175 – $400 |
| Minor repair (flashing, pipe boot, a few shingles) | $250 – $600 |

| Concrete tile full replacement | $15,000 – $35,000 |

Ontario’s wind damage and UV degradation can push repair costs up when multiple slopes are involved or the underlayment under tile has failed across a large area. Every estimate we give is line-item and fixed – the number we quote is the number you pay, and if anything changes once the roof is opened up, you’ll hear about it before we do the work.

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."
— Craig Miller"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."
— Beatriz Torres"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."
