Roof replacement and repair in Thousand Oaks
The Thousand Oaks housing element states that most of the city's housing was built between 1960 and 1989, with a third of it built in the 1970s, and that about 77 percent was built before 1990. About two-thirds of the homes are single-family detached houses.
A house from the 1970s is on its second or third roof by now, and earlier re-roofs were sometimes laid over old layers. A tear-off to the deck is the way to find out what is really there.
Roofing permits in Thousand Oaks
Thousand Oaks is its own city in Ventura County. Its municipal code requires a permit before a building is altered or repaired, and exempts only roof covering repairs of 100 square feet or less within any 12 months.

Tile roofs: the layer beneath wears out first
The tile sheds most of the rain, but the underlayment beneath it keeps the house dry. We lift the tile, renew that layer and relay the same tile.

Wind-blown embers start most roof fires. They land on the roof surface (1), blow in through vents (2) and collect in gutters (3). A Class A roof and ember-resistant vents deal with all three.
