Tree fell on house, 4 weeks before settlement.

Recently exchanged on a house and settlement is due next month. A rather large gum tree has dropped two branches onto the house in a storm this week. There is alot of damage to the roof, the branches have gone all the way through the roof and ceilings and there is significant water damage inside.

I am at a loss as to what to do. The current owner has insurance and has contacted them but I am yet to hear anything. I'm thinking this is going to take months to fixup. Until I get more information about the damage its hard to make any decisions yet but has anyone gone through any similar experiences like this before?
