Monte Vista tract houses and the roofs they have outlived

Montclair began as citrus country. The Monte Vista tract filled with houses after the war, became its own city in 1956, and took the name Montclair two years later. Most of what you see today dates from that stretch, and the Census median build year is 1969.

Houses of that age commonly carry a second roof, sometimes with a third patched over the top. Low eaves, shallow attic space and thin ventilation are common. Roofs that were new in the 1990s are now reaching the end of an ordinary shingle life, though the manufacturer's rated life governs.

Mills Avenue, San Antonio Creek and the Transit Center: how Montclair is laid out

Mills Avenue forms Montclair's western border, and it follows the route of San Antonio Creek, once called Arroyo de los Alisos. Pomona is across it to the west. The San Bernardino Freeway runs through the northern part of the city, Claremont and Upland lie to the north, Ontario to the east and Chino to the south, and the whole city covers 5.53 square miles at about 1,066 feet in elevation.

The settlement history is layered. A Township of Marquette was founded in 1897, the Monte Vista tract was surveyed in 1900 and the settlement of Narod followed in 1907. The Post Office objected to the name Monte Vista, which is how Montclair got its name in 1958. The Montclair Transit Center, with Metrolink, Foothill Transit and Omnitrans connections, makes the city a commuter hub.

For a roof, the housing numbers matter more than the map. The 2020 census counted 10,816 housing units, and the average household has 3.56 people. With that many people under each roof, we plan noisy tear-off days around the household and talk through the schedule before the first morning.

Reaching Montclair from Van Nuys

Montclair is about 58 miles from us, mostly freeway, and the time depends heavily on the hour. Ask for an honest arrival window when you call. We offer the earliest visit we can schedule, but a 58-mile trip rules out any talk of fast response.

The first visit takes in the roof surface, flashing, vents and the attic where reachable. You get photos, measurements and a written estimate, and with a leak we trace the source before quoting a repair, so you are not paying to patch the wrong spot.

Montclair building rules on the Los Angeles County line

Montclair borders Los Angeles County, but it sits in San Bernardino County and runs its own city government. A bid prepared for an address in Los Angeles does not carry over, so confirm the permit path with the city.

Two state rules matter on most jobs here. Two existing layers rule out a new one on top, and re-roofs that replace more than half the roof often must use a cool-rated product. Check the California Energy Commission's climate zone lookup for your address.

What customers say

“The crew’s workmanship looked top-notch, and they kept me updated by sending drone photos of the roof work as it happened, which was really helpful since I wasn’t about to climb up there myself!”

“When it came time for installation, Frederick and Jared expertly replaced three skylights for us, even though there were some light showers that morning.”

Roofing questions from Montclair

Who issues a roofing permit in Montclair?

Montclair is its own general law city, meaning the city, not San Bernardino County or Los Angeles, permits a re-roof. Put in the contract which party applies for the permit and schedules the city inspection, and hold the last payment until the sign-off is in writing.

Can a 1960s Montclair house get a new roof over the old one?

Only if the existing roof has fewer than two layers and is dry and sound. California's code bars a third layer and bars covering a soaked or deteriorated roof. Many houses from this era are already on a second roof, so we would usually look at a tear-off and inspect the decking first.
