Roofing Contractor in Ontario, CA

Ontario is about 59 miles and 110 minutes from our Torrance base, and the 10 and 60 carry heavy truck traffic, so the clock can change. Call first, tell us what the building is, and we will say when a visit fits. San Bernardino County is covered on our county service area page.

Warehouse roofs, flat roofs on older apartment buildings and metal roofs on industrial sheds make up most of what Ontario asks us about, with the older houses a distant second.

Distribution roofs near the airport

Ontario is a logistics city. Warehouses around the airport carry roofs measured in acres, and on a roof that size one failed seam or drain can cause a lot of interior damage. Ponding water, loose fasteners on metal panels and sealant that has split around vents are the usual causes. Our warehouse roof leak guide shows how we trace a source.

Euclid Avenue homes and Ontario's permit office

Ontario's old center runs along Euclid Avenue, laid out in the 1880s by the Chaffey brothers, and homes there are some of the oldest in the city. Aged composition roofs on bungalows are common, and the decking under them deserves a check.

Permits are issued by the City of Ontario's Building Department. We deal with the permit side of a re-roof, and you should confirm current requirements for your address. Our commercial re-roof and Title 24 guide explains why energy rules matter on a bigger project.

Ontario Ranch, the old dairy preserve and Title 24 on big roofs

South of the old center, Ontario Ranch was farmland and county dairy preserve until the city annexed about 8,200 acres of it in 1999 under the name New Model Colony. The first homes there went up in 2007, so roofs in that area are young and the calls are flashing and sealant. The warehouse stock is a different story. Large nonresidential re-roofs can trigger California Energy Commission Title 24 requirements, such as reflective roof surfaces, and the City of Ontario's Building Department confirms what applies to a given building. Ask for the roof area, slope and existing roof type to be written on the estimate so the permit review starts from facts.

Roof work Ontario calls for most

Booking a commercial roof visit in Ontario

Send the building size, roof type, how a crew reaches the roof and any hours restrictions. We book a free roof inspection and give you photos of each issue. If the building has tenants, we want to know who holds the lease and who authorizes work. Because the trip is long, we group visits, so a firm description of the problem speeds up the schedule.
