Dead trees in neighbors yard

[Trace Jones]

Last year, my neighbors pine trees were hit by lightning and the trees died. The neighbors made no effort to trim or cut down trees. Last week we had a storm, the dead trees broke off at top and damaged my property. I've fixed the damage. I know the neighbors are rarely home and I've sent a certified letter asking for them to take care of these trees before another damage occurs. Anything else I can do? These trees are certainly a danger now.
