Sorry to hear that mate! We were awake most of the night too, and Amanda scarily said if my car got damaged which insurance would you claim off if a roof tile fell on it!
I said as the damage was dont to the car, you'd claim off the car insurance and I think they would somehow counter claim against the house insurance. Just like if a car hit you, you claim through your insurance and they chase the other party on your behalf.
Best of luck with getting it sorted, thats gutting to hear.
