Oh god, how absolutely terrible. Once you can think again, I'd think about suing. That collection was worth so much money! You don't even need to sue for money though, just if you win the supposed roof repairman has to sit on your kitchen floor with super glue until all the pieces are restored to your satisfaction. And if he wants to drink tea he has to drink it out of his cupped hands. And no tasty baked treats, either!
