Contact Ontario Roof Pros for a free estimate

A real person from Ontario Roof Pros reads it, calls you back, and books a site visit — usually within one business day. We measure, look at the actual condition of the work area, and send a written, itemized free estimate. No deposit, no obligation, and no pressure call afterwards.

In a hurry? Calling (866) 875-9250 is always faster than a form.

Monday through Saturday, 8am to 6pm, with emergency calls answered outside those hours. Forms that arrive in the evening get a call back the next morning, and a site visit is usually booked within one to two business days depending on where in the Inland Empire and the eastern San Gabriel Valley you are.

Everything is handled by Ontario Roof Pros people in Ontario, CA — not an overseas call centre working from a script. If you would rather not explain the whole thing twice, calling (866) 875-9250 once beats a form and a follow-up.

Most of the requests that land here fall into a handful of jobs. If yours is on this list, there is already a page with scope, materials and pricing detail for Ontario:

• Residential Roof Installation — Roofing a structure that has no roof yet is a different job from replacing one. New houses, additions, garage conversions, a deck stripped to bare plywood because the sheathing is being replaced.
• Commercial Roof Installation — Ontario, California runs on buildings that cannot close. Fulfillment centers, cold storage, cross-docks and light industrial buildings around Ontario International all need roofing done around a shift schedule instead of in place of one, and that constraint shapes every decision.
• Roof Replacement — Replacement here comes down to one question: can the building keep working while the roof comes off? On a distribution building that answer drives the whole sequence, and on a house it decides how long the framing sits open to the sky.
• Roof Repair — Half the repair calls we take in this city are on a low-slope section rather than a pitched field, and the two want completely different answers. A membrane patch is not a scaled-down version of a shingle repair.
• Asphalt Shingle Roofs — Shingles cover most houses in this city, and the mistake we correct most often is shingles installed somewhere they do not belong: a low-pitched addition, a patio tie-in, a converted porch with barely any fall across it at all. Below four in twelve, shingles need doubled underlayment.
• Cool Roof Installation — If your Ontario roof is concrete or clay tile, the reflectance rows may already be answered for you. The thing that answers them is weight rather than color, and that changes the order of the conversation.

Rough measurements or square footage, photos of the area from a few angles, any material or finish you already have in mind, and your target timeline. None of it is required, but it makes the first free estimate far more accurate.

Nothing. The site visit and the written, itemized free estimate are free across Ontario and the Inland Empire and the eastern San Gabriel Valley, with no deposit and no obligation to book. We would rather price the job properly and lose it than win it on a number we made up over the phone.

Yes. Ontario Roof Pros runs its own crews in Ontario, CA — the people who quote your roofing job are the people who show up to do it. Licensed and insured California C-39 roofing contractor. C-39 covers what seals, waterproofs and weatherproofs a structure, and reaches edge metal and skylight curbs as work incidental and supplemental to the roof. Interior repairs beyond that are a different classification and we say so rather than stretch the license. We also carry workers' compensation, which a C-39 must hold whether or not it has employees, Fully insured and bonded. Nothing gets sold on to whoever is cheapest that week.
