Roofing contractors in Ontario
From Ontario Ranch, Downtown Ontario, and Creekside, the roofs across Ontario tell a consistent story: older downtown grid of early-20th-century homes plus massive new master-planned growth in ontario ranch to the south.. Concrete tile on new tracts and shingle on older homes; inland heat and UV dry underlayment, and older downtown roofs often carry multiple layers. That mix is what shapes almost every job we take on here.
Heat drives almost every roof failure in this part of the state. With deck temperatures topping 160 degrees on a summer afternoon, the felt underlayment under the tile bakes out and gets brittle decades before the concrete or clay tile above it does. The right repair reflects that: re-underlayment and a tile relay, not paying for new tile you do not need.
Brand-new Ontario Ranch tile roofs contrast with aging downtown homes that need full tear-off; both benefit from proper underlayment spec for the heat load. Whatever your roof needs, it starts the same way: a free inspection with a photo report, a straight recommendation, and a written scope before any work begins. Call (213) 289-2007 to get on the schedule.

Roofing FAQs — Ontario, CA
What does a new roof cost in Ontario?
Every roof is priced after inspection, but as a rough guide, a typical single-family reroof in Ontario usually falls into a range set by size, pitch, and material — asphalt shingle is the most affordable, concrete or clay tile costs more, and a tile lift-and-relay that reuses your existing tile lands in between. We give you a firm written number after we've seen the roof, not a guess over the phone.
Do I need a permit to reroof in Ontario?
Yes. Nearly every California jurisdiction requires a permit to reroof, and Ontario is no exception — the permit is pulled through the local building or building & safety department and the job is inspected. We handle the permit and schedule the inspections as part of the work.
Do you remove and reset solar panels for a reroof?
Yes. A lot of Ontario homes have rooftop solar, and a proper reroof means detaching the panels, replacing the roof underneath, and resetting them — not roofing around them. We coordinate the panel removal and reset so the roof under your array is done right.
How do I know if I need a repair or a full replacement?
It comes down to the underlayment and the extent of the wear. If the covering is sound and the problem is localized — a few cracked tiles, a failed flashing — a repair is the right call. If the underlayment is spent, leaks keep moving around, or the roof is near end of life, replacement is the better spend. Our free inspection and photo report give you the honest answer either way.
How long does a roof replacement take?
Most single-family homes in Ontario take two to five working days, depending on size, roof material, and access. Tile and steep or complex roofs take longer, and weather can add a day. We give you a realistic schedule with the written scope.
