Roofing in Ontario, CA
Our shop is on East Lowell Street in Ontario, so this is home. We work on every kind of roof in the city, from the older homes near downtown to the newest tile roofs in Ontario Ranch.
Older Homes Near Downtown
The streets around Euclid Avenue and downtown have homes from the 1920s through the 1960s. Many have been reroofed more than once, and some still have layers stacked on layers. On these homes we tear off to the original wood, replace what has rotted and start clean.
Tile Roofs From the 1980s and 1990s
North and south of the 10 freeway, many tract homes have concrete tile that is now 30 or more years old. The tile is fine. The paper under it is not. These roofs are the ones we re-lay most often.
Ontario Ranch
The new homes in the south part of the city are still young, and their roofs should be too. When we do get called there, it is usually for a cracked tile, a slipped ridge cap or a builder flashing detail that never sealed.
Permits Through the City Portal
Ontario runs reroof permits for detached single family homes through an online platform, and both contractors and homeowners can use it. A streamlined permit is still a permit, with fees and a final inspection. We pull it, book the inspections and meet the inspector. If you are not sure your address is inside city limits, the city's main line is (909) 395-2000.
Airport Wind and Summer Heat
The weather station at Ontario International Airport is the best record we have for roof weather here. A normal year brings about 93 days at 90 degrees or hotter, and that heat is what wears out shingles and the paper under tile. The same station logged a 76 mph gust in January 2025, the strongest of the last ten years. Every Ontario ZIP code is in state climate zone 10, so a reroof falls under the state cool roof rule.
