Roofing Contractor in Chino, CA

Wide low-slope roofs on Chino's commercial buildings

Chino's old dairy and farm land now holds large commercial buildings. Those roofs are broad and low-slope, which means water drains slowly and every seam, drain and rooftop penetration matters. A small leak at one flashing can run a long way before it shows on a ceiling.

We would assess a roof like that by walking it. We look at ponding marks, how the membrane is lapped and sealed, how drains and scuppers are set, and what earlier patches look like. A written estimate follows with options, not a single price.

Chino's 1980s subdivisions and the roofs on them

The city began as Rancho Santa Ana del Chino and spent a century in orchards, row crops and dairies. Housing filled in much later. The median Chino home dates to 1987 in Census figures, with 64 percent owner-occupied.

That puts a lot of roofs at 30 to 40 years old. Concrete tile commonly outlives the waterproof underlayment beneath it, so a tile roof can look fine while the paper has given up. Shingle roofs from the same years often show curling and granule loss after decades of hot, dry summers.

Dairy-era Chino: 121°F heat, 10 inches of rain and the Town of Chino

Chino sits at about 728 feet and averages only 9.98 inches of rain a year, with February the wettest month at 2.68 inches. It has also hit 121°F, in September. Dry heat of that kind cooks sealant, pipe boots and roof membranes for most of the year, then a short wet spell finds the weak spots.

The town was subdivided from Richard Gird's rancho land in 1887 and incorporated in 1910. Dairies flourished here from the 1950s through the 1980s, and the city still has many industrial areas. The Yorba-Slaughter Adobe, built in 1850, is one of the oldest standing buildings in San Bernardino County. Chino Airport, home of the Planes of Fame and Yanks Air Museum, are part of the same picture, a city where large buildings and old farm history sit side by side.

Chino permits and the 71 and 60 freeways from Van Nuys

Chino has its own building department, so permits do not run through San Bernardino County or Los Angeles. The unincorporated community of Narod lies just north of the city and falls under the county, so confirm which one holds your parcel. Whoever applies for the permit should be named in the contract. Re-roofs over half the roof area generally need a cool-rated product under California's Energy Code, so confirm the specifics with city staff.

The drive is about 59 miles by the 71 and 60 freeways, and rush hour changes it a lot. Ask for an arrival window when you call, and plan around it. The county context is on our San Bernardino County page.
