Related question, really came up last week.

Someone had a tree that neighbors were complaining about, that it looked
like it was dying and might fall on the neighbor's roof. On a windy day
recently it actually snapped -- but not falling on the roof, instead the
tree brought down the power lines. A number of people on the block lost
food before power was restored and other expenses were incurred. Is the
owner of the tree liable al pi din? What if the neighbor hadn't warned
him, so that we cannot know if the owner was aware of an issue or not?

Tir'u baTov!
