Fast, Reliable Roof Replacement Across Ontario
Roof replacement in Ontario, CA is rarely a simple tear-off-and-replace. Most homes in 91761, 91762, and 91764 were built between 1955 and 1975, so the real job is undoing 50 or 60 years of wind fatigue, UV damage, and layered-over mistakes before the new roof goes down. Our Roof Replacement crews know what a Santa Ana wind event does to the windward slope of a 1962 ranch on Euclid Avenue or a 1968 tract house near Colony High School, because we’ve stripped hundreds of them to the decking. If you’re pricing a new roof in Ontario, call (833) 467-4846. Ruben Castellano heads the crew, and he’ll tell you straight what needs to happen before any scope is written.
Why Tilecraft Roofing Is Ontario’s Preferred Roof Replacement Company
We didn’t earn our standing in Ontario by being the cheapest bid. We’ve been called back to Ontario neighborhoods again and again because we document what’s actually failing before we quote it. When a windward-facing rake edge peels in a Santa Ana event, the damage pattern tells us whether the original fasteners pulled, whether the starter strip was under-driven, or whether the decking was already soft from years of lifted shingles at the rake. Most Ontario roof replacements we survey on the north and west planes need fastener and edge-metal work that has nothing to do with what the shingle looks like from the street.
Our crews know Ontario’s grid well: the tract streets off Grove Avenue, the 1960s single-stories around Chaffey High School, the newer infill off Milliken and the 15. Our inspection-first approach means we don’t write a replacement quote until we’ve looked at the underlayment and the fasteners, not just the visible shingle layer. When we quote Ontario jobs, we quote the wind-hardening spec because that’s what determines whether the next roof lasts 8 years or 30.
Every Ontario roof we replace follows the same discipline: we look before we quote. The estimate is free, the written scope is line-itemed, and the pricing is fixed once we both sign it. Call (833) 467-4846 and we’ll schedule the inspection.
Styles & brands we work with
Roof Replacement Contractor in Ontario
Hiring a Roof Replacement Contractor in Ontario means hiring someone who understands that the biggest threat to your roof is uplift, not rain. Ontario sits in the Inland Empire’s semi-arid wind corridor. The Cajon Pass funnels Santa Ana gusts through at 60 to 80 mph, and those gusts hit the north and west faces of 1950s and 60s ranch roofs with a mechanical force that peels ridge caps, field shingles, and drip edge on the windward slope while the other side stays untouched. Our Roof Replacement in Ontario team scopes every job with that wind pattern in mind.
The Wind-Hardening Scope
On an Ontario roof that has been wind-tested, we re-specify fasteners first. Hot-dip galvanized or stainless ring-shank nails get the nod. The starter strip gets widened on the windward planes. Drip edge goes from lightweight to heavier-gauge metal at the rakes. These aren’t add-ons we offer; they’re standard because we’ve seen what the cheap spec does after three Santa Ana seasons.
When Replacement Beats Another Repair
If your roof is on its second or third layer of 3-tab or shake, or if the decking under the windward slope has gone soft from lifted shingles and 50 years of Inland Empire UV, repair won’t hold. Replacement is the cheaper move. We’ll show you the numbers, and we’ll only say replace when it’s actually replace time. That’s the Tilecraft way: repair when repair is right, replace when it’s not.
Asphalt Shingle Roof Replacement in Ontario
Asphalt Shingle Roof Replacement in Ontario is the most common job we do, but the material spec matters more here than it does in most Southern California cities. Inland sun in Ontario pushes summer rooftop temperatures past 140°F. That heat, combined with the wind uplift from Santa Ana events, means the shingle has to hold its nail line through thermal expansion and repeated mechanical stress. GAF Timberline and CertainTeed Landmark are both strong performers in this climate, but we’ll walk you through the trade-offs before you choose.
Architectural Shingles vs. 3-Tab in the Inland Empire
Most of Ontario’s aging roof stock is original 20-year 3-tab on its last legs or wood shake that was never rated for this wind corridor. Architectural shingles give you roughly 50 percent more material mass at the nail line, a thicker mat, and better uplift resistance under a 60 mph gust. The cost works out to about $4.50 to $6.50 per square foot installed in Ontario for architectural shingles, compared to roughly $3.50 to $4.50 per square foot for 3-tab over a standard 1,400-square-foot ranch.
Decking, Fasteners and Underlayment
On an Ontario home that still has the original 1960s skip-sheathing under a shake roof, we often replace decking rather than overlay. Blacker-than-expected deck photos from a windward corner mean the old fasteners have been working loose for years. We’ll quote the decking replacement as its own line item so you see exactly what you’re paying for. If the decking can stay, we still re-nail to modern wind codes and add ice and water shield in the valleys.
Trusted Brands We Service in Ontario
We install from seven major roofing brands, which matters in Ontario because climate and wind exposure should drive the material choice, not whatever the contractor happens to stock. Boral makes the clay and concrete tile systems we recommend for the eastern foothill edges of Ontario where newer infill demand style and heavier wind resistance. Atlas and Tamko both build architectural shingles that hold up well in the Inland Empire’s heat-plus-wind cycles. We stock common replacement parts for Ontario homes and can order any specialty profile within days, not weeks. If you want a specific material for your roof, you should be able to get it. That’s the whole point of a seven-brand lineup.

AfterCommon Roof Replacement Problems We See in Ontario Homes
- Windward-slope peel on 1960s ranch roofs. After a Santa Ana event, the north and west planes of an Ontario tract house lose ridge caps and field shingles at the rake edge. The leeward side looks untouched, so the fastener and starter-strip weakness gets missed by adjusters and roofers who don’t see these homes every week.
- Lifted drip edge and fatigued rake metal from repeated uplift cycles. Ontario’s wind is not a one-time storm; it’s a seasonal cycle that works the edge metal until it loosens, then the next shingle above the loose edge lifts. That’s why we quote heavier-gauge drip edge on any Ontario replacement.
- UV-degraded 3-tab or wood shake on a second or third layer. Much of Ontario’s 91761, 91762, and 91764 housing stock still has original 3-tab or wood shake that is over 50 years old, with multiple reroofs layered over it. The upper layer often looks “okay” while the fasteners have lost their bond and hidden soft decking sits underneath.
- Valley failure where wind and heat combine. Ontario’s older homes have open valleys that trap debris and then get baked by the inland sun. When a Santa Ana hits after a long dry spell, the valley shingles are brittle and loose at the same time. Sealing the valleys and adding ice and water shield is part of our standard wind-hardening scope.
Pricing for Roof Replacement in Ontario, CA
A full tear-off and replacement on a typical 1,200 to 1,600 square foot Ontario ranch runs $9,500 to $16,500 for architectural shingles, depending on decking condition, number of layers to remove, and whether we need to re-spec the fasteners and edge metal on the windward planes. A tile roof replacement on steeper-pitch foothill homes runs higher, typically $18 to $32 per square foot installed. For original shake that has to come down to the decking, expect to add $1,500 to $3,500 for decking replacement on the worst windward corners. The free estimate we give you will show the coastal-spec vs. wind-hardening-spec line items side by side. Call (833) 467-4846 to schedule yours.

FAQs About Roof Replacement in Ontario
The Cajon Pass directs Santa Ana gusts right into the northern and western planes of Ontario’s 1950s and 60s ranch roofs, and the windward slope takes the mechanical peel force while the leeward slope never sees it. If you’re comparing quotes for an Ontario roof, ask each bidder whether they walked both slopes and documented wind-scour on the windward plane for your insurance adjuster. Call (833) 467-4846 and we’ll do exactly that before writing your estimate.
Not the way it does in Huntington Beach or Newport, because Ontario’s salt-air problem is wind-driven, not spray-driven. The real issue here is the wind itself, not corrosion. Ontario’s inland climate means you’re upgrading fasteners, starter strip, and drip edge to resist uplift fatigue, not marine corrosion. We still spec hot-dip galvanized or stainless hardware because it’s the better product, but the reason is wind-hardening on the north and west planes near the Cajon Pass corridor. Call (833) 467-4846 for a quote that includes the right fasteners.
We strip to the decking, re-spec the fasteners to hot-dip galvanized or stainless ring-shank nails, widen the starter strip on the windward planes, and install heavier-gauge drip edge at the rakes. On a 1962 ranch in 91761 after a fall Santa Ana, we followed exactly that process and added ice and water shield in the valleys before reinstalling architectural shingles with a verified nailing pattern. The shingle’s wind rating only counts if the fasteners and edge metal can hold it. Call (833) 467-4846 to schedule an inspection and we’ll show you the spec.
In most Ontario cases, no, because a third layer adds weight the wind will use against you and hides the soft decking we already see on these 50-plus-year-old roofs. An original shake or 3-tab on a second layer usually fails at the fasteners before it fails on the surface, so replacing over it means the next roof is anchored to a weak foundation. We strip it and give you a real picture of what’s underneath. Call (833) 467-4846 for a free estimate on the tear-off.
Ask whether the bid includes heavier-gauge drip edge, what fastener spec is on the windward planes, and whether the decking under the rake edges has been inspected. In Ontario, the win is in those details, not in the shingle brand. We’ll show you the wind-hardening line items on every quote we write, and we’ll show you the same line items the cheaper bid left out so you can compare real to real. Call (833) 467-4846 and we’ll walk the roof together.
