The crash happened Sunday night. The homeowner says Farmers Insurance finally agreed to send out an adjuster on Wednesday.
Aerial footage from AIR7 showed the front end of the car wedged inside the home and the rear bumper poking out of the roof.

Initially, it appeared the car rolled down a hill into the home, but investigators believe the elderly woman who was driving fell asleep at the wheel.
