Roofers in Ontario, CA
Roof inspection in Ontario is the starting point for nearly every job we take on, and it’s the one service every homeowner in this city should schedule before deciding on repair or replacement. Ontario’s housing stock skews toward 1950s through 1970s tract homes, and the Santa Ana winds that tear through the Cajon Pass don’t just age roofs here, they mechanically pull them apart, shingle by shingle, ridge cap by ridge cap. That’s why we look before we quote. If you need a roofer in Ontario who gives you an honest assessment instead of a sales pitch, call Tilecraft Roofing at (833) 467-4846.
Why Ontario Homes Are Different
Most of Ontario’s core neighborhoods, including the 91761, 91762, and 91764 ZIP codes, are built on mid-century ranch and tract layouts. Single-story homes with low-pitch gable or hip roofs, originally finished in wood shake or 3-tab asphalt, are now fifty to seventy years old. Many of those roofs are on their second or third layer, which means the decking underneath has been carrying weight it was never designed for, and the fasteners holding everything down have been through decades of thermal cycling.
What really sets Ontario apart from the LA basin or the coast is wind. The Santa Ana events that roll through from fall to winter push 60 to 80 mph gusts down through the Cajon Pass, and those winds hit Ontario’s windward-facing roof slopes harder than almost anywhere else in the Inland Empire. We see the same pattern after every major wind event: north and west facing planes lose ridge caps and field shingles at the rake edge, while the leeward side looks untouched. Rain is rarely the primary cause of premature roof failure here. It’s uplift and UV. Summer temperatures routinely cross 100°F, and that heat accelerates shingle granule loss and edge-metal fatigue in ways coastal roofers don’t deal with.
For homeowners in the eastern foothill edges and newer infill developments, tile roofs on steeper pitches are more common. Those roofs have their own Ontario-specific issues, mostly around cracked tile from wind-driven debris and underlayment that bakes out in the heat. Different roof, different failure mode, different repair approach.
Styles & brands we work with
Our Main Ontario Services
The two services Ontario homeowners call about most often are repair and full replacement, and each one depends on an inspection-first approach so you’re only paying for work that’s actually needed.
Roof Repair in Ontario
Repair work in Ontario usually starts with wind damage. A Santa Ana event pulls shingles loose on the windward slope, and within a few weeks water finds the exposed underlayment. Other common repair calls include cracked tile on foothill homes, failing flashing around chimneys and vents on 1960s ranches, and deteriorating pipe boots. The key on these older tract homes is matching what’s already there, and with access to seven major roofing brands, we don’t have to force a mismatched product onto your roof. Roof Repair in Ontario is the right call when the roof decking is still sound and the damage is confined to a specific area.
Roof Replacement in Ontario
Replacement is the honest recommendation when a roof has reached the end of its useful life, which for many original Ontario wood shake and 3-tab asphalt roofs happened years ago. The decision point is usually whether the decking has started to fail, whether there are multiple layers already in place, or whether wind damage has become chronic rather than isolated. Ontario’s heat and wind cycle shortens asphalt shingle life compared to coastal installs, so we scope replacement with materials that fit the specific exposure pattern of your roof plane. Roof Replacement in Ontario includes tear-off, decking assessment, underlayment, and the right material for your roof, whether that’s GAF Timberline for longevity or Boral for clay tile aesthetics.

Roof Inspection in Ontario
Roof inspection in Ontario is how we determine whether a roof needs repair, replacement, or nothing at all yet. Most Ontario homes were built between 1950 and 1980, and after fifty-plus years of Inland Empire UV exposure and repeated Santa Ana wind events, the question is rarely if a roof has problems, but how far those problems have progressed and what it will cost to address them. Our Roof Inspection service is a standalone diagnostic, not a replacement funnel, so you’ll get a straight answer about the condition of your roof and what it needs.
Roof Inspection Services
Signs you need it
Granule buildup in gutters, curling or missing shingles on the north and west slopes, water staining on ceilings, and any visible lifting at rake edges after a wind event are all signals that your Ontario roof needs a professional inspection.
What it costs in Ontario
Roof inspection in Ontario typically ranges from $200 to $500 depending on roof size, pitch, and whether thermal or drone imaging is needed to document wind scour that isn’t visible from the ground.
How we do it
We inspect the field shingles, ridge caps, flashing points, pipe boots, valleys, and drainage, then document windward slope damage with photos so you have a written record for insurance or future planning.
Roof Estimate
Signs you need it
You need a roof estimate when an inspection has identified repairable damage or full replacement is on the table, and you want a scope of work with material options and a line-item price.
What it costs in Ontario
A written roof estimate in Ontario is typically free as part of our inspection service, though a detailed materials comparison across multiple brands may run $200 to $500 depending on the level of documentation required.
How we do it
We measure the roof, assess decking condition where accessible, and produce a line-item quote that breaks out materials, labor, and any structural work so you see exactly what you’re paying for.
Free Roof Inspection
Signs you need it
If you’ve noticed new leaks after a rain event, missing shingles after a wind storm, or you’re preparing to sell a 1950s or 1960s Ontario home, a free roof inspection gives you a condition baseline before any money changes hands.
What it costs in Ontario
Free roof inspection in Ontario is available for standard single-story ranch homes with walkable low-pitch roofs, while steeper hillside or tile roofs may require a paid inspection under $500.
How we do it
We walk the roof where safe, inspect all penetrations and edges, and give you a verbal summary of what we found with photos so you know whether a full written report is worth the next step.
Hail Damage Roof
Signs you need it
After a hail event, look for dents in soft metals like vents and flashing, pockmarks or bruising on asphalt shingles, and cracked or dislodged tile on Ontario foothill homes.
What it costs in Ontario
Hail damage roof inspection in Ontario falls within the standard $200 to $500 inspection range, and includes documentation that insurance adjusters can use to assess a claim.
How we do it
We inspect all planes for impact damage, check the soft metals for dent patterns that confirm hail size, and photograph everything so you have the evidence you need for an insurance filing.
Roof Inspection Companies
Signs you need it
If you’ve been told by another contractor that you need a new roof but no one has actually documented the damage, you need a second opinion from an inspection-focused roofing company before you commit to a five-figure job.
What it costs in Ontario
A second-opinion inspection from a roof inspection company in Ontario typically runs $200 to $500, and you receive a written report with photos and an honest recommendation on repair versus replacement.
How we do it
We perform the same inspection whether we quoted the work or not, with no incentive to recommend replacement over repair, and no pressure to act on anything we find.
What Roof Inspection Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Standard roof inspection (single-story, low pitch) | $200 – $350 |
| Tile or steep-pitch roof inspection | $300 – $500 |
| Free roof inspection (walkable asphalt roof) | $0 |
How long does a roof inspection take in Ontario?
A standard single-story ranch roof inspection in Ontario takes 45 to 90 minutes on site. Steeper foothill homes with tile and multiple planes run up to two hours.
Do I need a roof inspection before filing a wind damage claim in Ontario?
Yes. Ontario insurers often ask for documented windward slope damage, because Santa Ana uplift patterns are localized and adjusters miss rake-edge lifting. A written inspection with photos gives you a stronger claim. Call (833) 467-4846 to schedule yours.
Brands We Service in Ontario
Tilecraft Roofing works with seven major manufacturers, and for Ontario jobs we most often turn to GAF for shingle longevity, CertainTeed for mid-range flexibility, Tamko for value-driven compositions, and Boral for tile systems on foothill and custom homes. Parts and materials are sourced directly from manufacturer supply lines, which keeps turnaround predictable even on wind-damage repair schedules. See our brands for the full material lineup.

In Ontario, two factors push pricing higher than neighboring cities. The first is wind-damage remediation on 1960s tract roofs, where aging decking and compromised fasteners often require more structural work than a simple shingle overlay. The second is municipal code compliance on multi-layer tear-offs, which adds disposal and permit costs that don’t exist on clean single-layer jobs. Tilecraft Roofing prices every Ontario job with a written line-item estimate before work starts, and we don’t change the number after we begin.
Neighborhoods We Serve in Ontario
We work across Ontario’s core residential areas, including the older ranch-home streets in the 91761 and 91762 ZIP codes, the newer infill developments on the south side, and the foothill-adjacent tile roof homes near the 91764 area. Our crews are familiar with the specific roofing stock in each part of the city, from original shake tear-offs on mid-century lots to tile resets on steeper eastern pitches.

FAQs About Roofers in Ontario
Yes. The City of Ontario requires permits for full roof replacements and for repairs that involve structural decking work. Simple shingle or flashing repairs typically don’t need one. We handle the permitting on every replacement job and can tell you at inspection whether your repair will trigger a permit. Call (833) 467-4846 if you’re not sure.
Within one to two weeks, even if you don’t see obvious damage. Wind scour on windward slopes starts small, with lifted shingle tabs and loosened ridge caps, and gets worse with every subsequent event. Documenting it early, before the next rain season, keeps a small repair from becoming a full decking replacement. Estimates for wind-damage inspections are free during the fall and winter months.
We do. The older single-story ranches in the 91761 and 91762 areas usually need composition shingle or shake-focused repair work, while the newer foothill and infill homes in 91764 trend toward tile and need a different skill set. With seven brand partnerships, including Boral for tile systems, the same crew handles both. Call (833) 467-4846 and tell us which part of Ontario you’re in.

What Ontario Customers Say
"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."
— Oscar Morales"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."
— Rosa Garcia"Flashing where the roof meets the chimney had never been done right by the original builder. He rebuilt it properly with step flashing instead of just running a bead of caulk over it like the last two people did."
— Daniela Delgado
