Did the roofer do any structural work or simply replace tiles, battens and felt, if he did any structural work then he may bare some responsibility. However if you have simply had him replace the roof covering then not sure he has any blame to carry, did you use a building inspector ensure building regulations were adhered to and also that the roof structure could 1. Could cope with being messed about with without and extra timber and 2. Could cope with a heavier load from New tiles (new tiles tend to be heavier than old ones. Either way tiles shouldn't fallng off even with some small spreading, obviously you you got a photocopy of the roofers public liability insurance certificate as well as its such a crucial part of a house
