[quote=ltsdd]I think OP’s real question is – is the neighbor responsible for the damage being wreaked by their tree/roots?[/quote]

I remember seeing something on the news or in Piggington recently about trees that fall over during storms and damage the neighbors property. In those cases, the property owner whose yard the tree was growing in has no liability or at least the responsibility to fix the damage is with the insurance of the affected party not the party that owns the tree.
