Your house has no insurance some roof tiles brew off and damaged next door can your neughbouor clain on his insurance and who pays?

The next door neighbor can file a claim and it will be covered under wind damage. However, it is more than likely his deductible will be higher than the expense to repair the damaged shingles. A small claims suit would likely go to the neighbor who was damaged. If the offending home had insurance the neighbor could file a liability claim and possibly receive damages.
