Fast, Reliable Roof Replacement Across Ontario
Roof replacement in Ontario, CA typically costs $9,800 – $18,500 for a standard single-story tract home, with tile re-roofs running higher than asphalt shingle tear-offs. Most Ontario jobs take 2 – 5 days once materials are on site. We work throughout Ontario’s postwar neighborhoods weekly, from the Montclair grid to the newer Ontario Ranch edges. If you’ve spotted a ceiling stain after the first winter rain or your tile roof is entering its fourth decade, call (877) 731-1384 and we’ll give you a straight diagnosis before any pricing conversation starts.
Why Hawk Roof Repair Is Ontario’s Preferred Roof Replacement Company
Ontario is a tract-home town. The housing stock across the city, whether you’re west of the 10 near Montclair or south toward the Ontario Ranch build-out, is overwhelmingly single-story stucco built between the early 1960s and late 1980s. We’ve replaced roofs in Ontario long enough to know what those homes hide: baked-out felt underlayment beneath tile that still looks serviceable from the curb, dry-rotted fascia boards at the eaves, and original nailing patterns that would never pass today’s wind-uplift standards.
Noel Ibarra leads every estimate walk in Ontario. We show up with a ladder and a moisture meter, not a contract. Our inspections are standalone, documented, and scoped before any replacement conversation begins. Ontario homeowners call us because we’ll tell them what’s actually failing, not what’s convenient to sell.
We carry materials from seven leading manufacturers, GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so an Ontario homeowner can match an existing tile profile exactly for HOA compliance or choose a more economical asphalt shingle system without us pushing one brand. One company handles inspection, repair, and full replacement.
Styles & brands we work with






New Roof Installation in Ontario
New Roof Installation in Ontario runs $11,500 – $21,000 on a typical 1,400 – 1,800 sq ft tract home, depending on material choice, decking condition, and whether we’re pulling a permit through the City of Ontario. This is a full tear-off-to-decking job: old roofing removed, sheathing inspected and replaced where dry rot has set in, new underlayment installed to current code, and new roofing applied with fasteners that meet or exceed the current wind rating for Ontario’s Santa Ana exposure.
Homeowners in Ontario’s older subdivisions, particularly those built before 1985, usually need this route rather than a simple overlay. The original decking often has sections of rot around penetrations and at eave edges where decades of winter rain found a path through failed underlayment.
Decking and Dry Rot Repair
We scope decking replacement before we quote. Ontario’s hot, dry summers don’t rot wood the way coastal humidity does, but leaking tile underlayment traps moisture against sheathing for years before anyone notices the ceiling stain. We replace rotted sections with CDX plywood or OSB to match the existing decking thickness, and we document every section we open so you see exactly what we found.
Asphalt vs. Tile for Ontario Homes
Tile roofs dominate Ontario’s older tract neighborhoods because HOAs wrote them into the original CC&Rs. Asphalt architectural shingles are the practical choice for newer Ontario Ranch homes and owners whose HOAs allow a change. We’ll show you pricing for both paths, with manufacturer-backed warranties from whichever brand you choose.
Reroofing in Ontario
Reroofing in Ontario is the most common job we do, and it typically runs $9,800 – $16,500 for a standard single-story home. Reroofing means removing the existing roofing layer and installing a new one over the existing decking, which works when the decking is structurally sound and the homeowner wants to refresh the roof without a full system replacement. For many Ontario tract homes with older tile that has begun failing at the corners or lifting during Santa Ana winds, this is the right scope.
Not every roof qualifies. If the decking has rot or the existing underlayment has failed, a reroof that doesn’t address those layers just buries the problem. We inspect first, every time, and if the decking is compromised we’ll tell you why a full New Roof Installation is the honest recommendation.
Tile Matching and HOA Coordination
Ontario’s tract subdivisions enforce uniform roof appearance. A reroof that doesn’t match the original tile profile and color can trigger a violation notice and an expensive redo. We match existing tile before we order a single piece, using the same manufacturer lines, GAF, Boral, and Atlas among them, so your reroof passes HOA review the first time.
Underlayment Replacement
We recently completed a roof replacement on a 1960s single-story stucco home in the Montclair area of Ontario. The barrel tile looked fine from the street, but when we stripped it, the original felt underlayment was baked and torn across the entire decking. We installed new GAF underlayment, replaced dry-rotted fascia and sheathing, and matched the existing tile color to satisfy HOA rules. That’s the typical Ontario job: the visible layer is fine, the hidden layer is done.
Trusted Brands We Service in Ontario
Hawk Roof Repair works with seven leading shingle and roofing material brands, including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. Your roof gets the right material for your home and your budget, not whatever we happen to stock. For Ontario customers we keep common tile profiles and asphalt shingle colors in local circulation, which shortens material lead times on reroofs and replacements throughout Montclair, the Ontario Ranch edges, and the central tract grids. We inspect first, then match the material to the structure and the HOA rules, never the other way around. See our Roof Replacement page for more on how we scope full system jobs.
Common Roof Replacement Problems We See in Ontario Homes
- Underlayment failure beneath intact-looking tile. Ontario’s dry inland heat bakes the felt paper under tile until it tears and separates. The first heavy winter rain then sends water through the cracked tiles onto failed underlayment, and the homeowner sees a ceiling stain in a bedroom that never leaked before.
- Santa Ana wind-uplift on aging asphalt shingles. Fall and winter wind events lift shingles that were nailed to the wrong pattern decades ago. On 40- to 60-year-old tract homes, original nailing doesn’t meet current wind ratings, and loose shingles become missing shingles by the next morning.
- HOA uniformity violations. Ontario’s tract subdivisions run on uniform roof appearance. A reroof that doesn’t match the original tile profile and color gets flagged, and the homeowner faces rework costs or fines. We match before we install.
- Dry rot at eaves and penetrations. Decades of intermittent leaks around vents, chimneys, and plumbing stacks rot the decking and fascia from the underside. We find it when we open the roof, and we replace it rather than roofing over it.

AfterPricing for Roof Replacement in Ontario, CA
Roof replacement in Ontario, CA lands between $9,800 and $21,000 for most single-story tract homes. A straightforward asphalt shingle reroof over sound decking sits at the lower end. A full tile replacement with new decking, new underlayment, and HOA-matched tile runs toward the top. Decking replacement adds $1.50 – $2.75 per square foot when rot is found. Material choice moves the needle: architectural asphalt is the economical path, while tile systems from Boral or Atlas carry higher material costs and longer lead times. We don’t change the price once we open the roof, and we don’t push you toward a pricier system than your home needs. Call (877) 731-1384 for a free estimate with line-item scope.

FAQs About Roof Replacement in Ontario
Because the failure is underneath the tile. Ontario’s inland heat bakes the felt underlayment until it tears, and water entering through cracked or loose tile then finds the damaged paper beneath. The tiles look intact from the street, but the waterproof layer is gone. We find this on most tile roofs we open in Ontario’s older tract neighborhoods. Call (877) 731-1384 to schedule an inspection at your Ontario home.
Most Ontario tract HOAs do require matching tile profile and color on re-roofs, yes. The communities built from the 1960s through the 1980s wrote uniform roof appearance into their CC&Rs. We match the existing tile exactly before ordering, which keeps your replacement compliant and avoids rework or fines.
Santa Ana winds exploit weak nailing. On older Ontario homes, original shingle nailing patterns don’t meet current wind-uplift standards, and tile installations with corroded or under-driven fasteners lose pieces during fall and winter wind events. Our replacements use current wind-rated fastening schedules appropriate for Ontario’s exposure, and we check the existing roof’s nailing during inspection.
Ask whether the decking will be inspected and rot replaced, whether the underlayment will be replaced or buried, and whether the tile or shingle will match your HOA’s requirements. Also ask what wind rating the fastening meets. If a quote skips those points, it’s not scoped to Ontario’s actual conditions. Call (877) 731-1384 for a written, line-item estimate that covers all of it.
Most single-story Ontario tract homes finish in 2 to 5 working days from tear-off to final cleanup. Tile systems and jobs with significant decking replacement run toward the longer end. Weather delays during winter rain or Santa Ana wind events can extend the schedule, and we’ll tell you before we start if a storm window looks risky.
