AfterFast, Reliable Roof Installation Across Ontario
A full roof replacement in Ontario typically runs $11,500 – $18,400 for a standard architectural shingle roof on a 1,500 – 2,200 square foot home, with most projects completing in 3 – 5 working days once materials are on site. That’s the honest range we give homeowners before anyone climbs a ladder. Our Roof Installation team works throughout Ontario every week – from the historic streets near Euclid Avenue to the newer developments off Archibald – and we know this city’s roof requirements cold.
At Crestview Roofing, you get a written price before any work starts, a live trackable arrival time the morning of the job, and before-and-after photos of every layer, sent to your phone. If you’re weighing a new roof in Ontario, call (325) 246-5075 for a free estimate. A real person answers, day or night.
Why Crestview Roofing Is Ontario’s Preferred Roof Installation Company
We’ve torn off and installed roofs across Ontario, from single-story ranchers built in the 1960s south of the 10 freeway to two-story stucco homes up in the Creekside area. That range matters, because the age and framing style of Ontario homes varies block by block. Some need full re-decking. Others just need new underlayment and shingles. We don’t guess – we inspect, document, and put the exact scope in writing.
Every Crestview crew member is background-checked and uniformed, so you know who’s pulling up to your curb before they ring the bell. When we schedule an installation in Ontario, you receive a live arrival link – the same standard Dylan Pace built into The Relay Visibility Guarantee. Homeowners near Chaffey High School and in the Ontario Ranch master-planned communities have told us the same thing: knowing the price and seeing photo proof of the stripped deck, the new underlayment, and the finished ridge line changes the whole experience.
Our technicians are manufacturer-certified to install GAF, CertainTeed in Ontario, Owens Corning, and IKO systems. That matters when you need a warranty that actually pays out if something fails. And it’s backed by our 365-Day Done Right Promise: if any covered repair fails within a full year, we return and fix it – no charge, no negotiation.
Standing Seam Metal Roof in Ontario
Standing Seam Metal Roof installation in Ontario runs $16,800 – $29,500 on a typical home, and it’s the option we recommend most often for homeowners who plan to stay put through decades of inland sun and Santa Ana winds. The system is exactly what it sounds like: vertical metal panels with raised seams that lock together, so there are no exposed fasteners and no shingle tabs for wind to lift.
Heat Performance and Installation Sequence
Ontario’s summer afternoons regularly pass 100°F, and that changes how metal roofs go on. Panels expand and contract more than shingles, so we set clips and fasteners with the proper slot allowance. Skip that step and you’ll get oil-canning – visible ripples across the face of the panels. Our crews sequence the work to avoid leaving cut panels sitting in direct sun, which keeps expansion marks out of the finish.
Why Homeowners Choose It
A standing seam roof can last 40 – 60 years with almost no maintenance, which is why we’re seeing more of it on custom homes in the hills north of the 210 and on ranch-style properties with low slopes. The material cost is higher than asphalt, but the lifetime cost usually wins. If you want a firm number for your Ontario roof, call us and we’ll walk the roof measurements with you.
Tile Roof in Ontario
Tile Roof installation in Ontario typically runs $18,200 – $34,600 depending on whether we’re setting concrete or clay tile and whether the original decking can stay. Spanish and mission-style tile is everywhere in this city – drive through any neighborhood off Vineyard Avenue and you’ll see it on half the homes. It looks right for Southern California, and done correctly, it lasts 50 years or more.
What Re-Decking Actually Means
Many Ontario homes with original 1950s and 1960s tile still have skip sheathing underneath – 1×6 boards spaced apart, never designed to hold modern tile weight evenly. When we tore off a 22-square tile roof in Ontario’s Historic Downtown area, the skip sheathing wasn’t flat enough for new tile without a plywood overlay and a full ice and water shield layer in the valleys. That’s the kind of thing a drone inspection misses and an honest tear-off reveals.
Valleys, Flashings, and the Inland Heat Problem
Ontario’s heat creates a specific failure mode on tile roofs: adhesive-backed underlayment left exposed on a hot afternoon softens and wrinkles, and those humps show through the finished tile forever. We sequence each section so underlayment gets covered the same day it goes down. New drip edge, new counterflashing at every penetration, and a ridge vent across the main hip – those aren’t upgrades, they’re the correct way to install tile here.
Trusted Brands We Service in Ontario
Crestview Roofing installs and services roofing systems from GAF, CertainTeed, Owens Corning, and IKO, and we stock the fasteners, ridge caps, and underlayment those systems spec for Southern California’s climate. When an Ontario homeowner calls us about a specific manufacturer warranty question, we can pull up the product line and answer same day. You don’t have to wait for a rep to call back from a distribution center. If you’ve already picked a brand for your Ontario home, we’ll quote it straight and install it to the manufacturer’s published requirements.
Common Roof Installation Problems We See in Ontario Homes
- Wrinkled underlayment baked into the roof: Ice and water shield left exposed during a 100°F afternoon softens and wrinkles, creating humps under the finished shingle or tile. We cover sections the same day they’re laid, because re-doing a wrinkled underlayment means tearing off everything above it.
- Nails that never bite: Decades of inland heat cycling leaves decking that looks solid from the attic but has hidden dry rot at the edges. Fasteners through that wood fail at the first Santa Ana event, and shingles peel off in the night. We probe every sheet of decking and flag replacement in the written quote, not as a surprise after tear-off.
- Reused flashing at valleys and chimneys: Flashing that gets bent back and reused instead of replaced fails in the first heavy winter rain. The leak shows up as a ceiling stain in a bedroom far from the actual penetration, which makes it miserable to diagnose. We replace flashing on every installation, no exceptions, and we photograph it before it’s covered.
- Wrong underlayment for the slope: Some older Ontario homes have low-slope sections that shingle manufacturers won’t warrant without a specific peel-and-stick system. A roofer who skips that step hands you a voided warranty. We check slope on every plane of the roof and adjust the system accordingly.
Pricing for Roof Installation in Ontario, CA
Here’s what we quote for a full tear-off and installation in Ontario. Architectural shingle roofs on standard 1,500 – 2,200 sq ft homes land between $11,500 and $18,400. Tile runs $18,200 – $34,600 and standing seam metal runs $16,800 – $29,500, both dependent on decking condition, roof complexity, and whether we’re replacing gutters or adding new ventilation. What moves the number: re-decking (usually $1,800 – $4,200 extra depending on how much plywood is rotten), the roof’s slope and number of planes, and whether existing tile or shakes need disposal. You’ll get a written price before any work starts, and that’s the number on the invoice.

FAQs About Roof Installation in Ontario
Put both quotes side by side and check four lines: decking, underlayment, flashing, and ventilation. Two quotes can differ by $5,000 because one includes full re-decking and new drip edge while the other plans to reuse what’s there and nail through old wood. Make both roofers commit, in writing, to what happens if the decking is rotten once the old roof comes off. Then call (325) 246-5075 and we’ll help you read both line items honestly – even if you go with the other bid, you’ll know what you’re signing.
Yes, the City of Ontario requires a building permit for roof installation, and the permit includes a final inspection by the city after the work is complete. We pull the permit, schedule the inspection, and walk the job with the inspector when they arrive. A roofer who wants to skip the permit is handing you a title problem and a code problem if you ever sell the house.
Tile and standing seam metal outperform asphalt in Ontario’s climate over a 30-year window – tile because it has thermal mass and doesn’t cook from the sun the way shingles do, metal because it reflects heat and doesn’t degrade from UV exposure. That said, a properly installed GAF or CertainTeed architectural shingle roof with correct ventilation will last 25 – 30 years in this climate. The right answer includes your budget and how long you plan to own the home.
Most Ontario roof installations take 3 – 5 working days on site once materials are delivered, with the full permit-to-inspection timeline around 2 – 3 weeks depending on city plan check turnaround. Tear-off, decking repair, underlayment, and installation usually run on consecutive days. The city’s inspector comes after we finish, and we handle that scheduling for you.
The only thing that changes your price is what we can’t see until the old roof comes off – rotten decking, failed flashing, or structural issues hidden under the old material. That’s why we photograph everything during tear-off and give you a written change order before any replacement work begins. You approve the number before we spend the money. Call (325) 246-5075 for an exact quote – estimates are free, and the price we hand you is the price you’ll pay unless the decking underneath tells us otherwise.
