Roofing Contractor in Casa Conejo, CA

Casa Conejo's 1960 start and why its roofs are at repeat re-roof age

Casa Conejo was the first planned community in Newbury Park, with construction beginning in 1960. That puts the oldest roofs here well past their original lives. Census ACS data gives the median home as built in 1965, with 93% of homes owner-occupied, so most owners have already been through at least one re-roof.

A house on its second or third covering raises two questions. How many layers are down, and what shape are the boards under them? Two existing applications are the limit, and a third cannot go on top. A tear-off lets us count the layers and check the decking before a new covering goes on. See roof replacement for how that process works.

A county island inside Thousand Oaks: who issues the permit

Thousand Oaks incorporated in 1964, four years after Casa Conejo broke ground, and pulled the surrounding developments into the city. Casa Conejo stayed outside. Voters here rejected annexation in the 1980s, so the community is an unincorporated island whose re-roof permits generally come from Ventura County Building and Safety. The Casa Conejo Municipal Advisory Council advises the Board of Supervisors, but it does not issue permits.

The line can be a few steps away. An estimate prepared for a Thousand Oaks address may not apply to a Casa Conejo parcel. For the wider picture, read about Ventura County.

Low-pitch 1960s ranch roofs: attics, vents and old skylights

Mid-century ranch homes tend to have long, low roofs, deep eaves and shallow attics. Heat gets trapped under the surface, and the ventilation that was adequate in 1965 may not be now. Old plastic skylight domes crack and leak at the curb. A skylight, an attic vent, or a gap at a chimney is usually where water enters first.

Homes of this era can also have spaced boards rather than solid plywood under the roof, which changes how a new covering is fastened. We show you anything soft before we replace it. Read about skylights and ventilation if your attic runs hot.

Statewide, a cool-roof-rated product is generally needed when a re-roof covers more than half the roof. Some older roofs also include materials that may contain asbestos, and if we see signs we recommend lab testing before removal.

Arroyo Conejo, Borchard Park and the streets around Casa Conejo

Casa Conejo covers less than half a square mile, at about 653 feet of elevation, so one storm tends to reach every roof in the tract at once. Arroyo Conejo, the longest creek in the Conejo Valley, crosses the southern part. The Ventura County Watershed Protection District manages the creek itself, so lots along it deserve a look at drainage and downspout outlets.

Borchard Community Park, Knoll Park and Newbury Park High School sit right beside the tract, and Sequoia Middle School marks its eastern edge. Trees at park edges can drop leaves and twigs on nearby roofs, so valleys and gutters are the first places we look after a windy week.

Fire history is part of the picture too. When the Hill and Woolsey fires started on November 8, 2018, most of Newbury Park was evacuated for two to three days, although no structures there were lost. Check your address on CAL FIRE's hazard viewer, and ask which roof covering rating your product carries before you choose.

A compact Casa Conejo visit, 37 miles from Van Nuys

The neighborhood is a rough rectangle bounded by Old Conejo Road and the 101, Borchard Road, Jenny Drive and Sequoia Middle School. By our estimate it is about 60 minutes from Van Nuys, and the 101 sets the real time. We write up what we find after the visit, with the layer count and board condition spelled out.
