Property Management company coordinating with neighbors

[Paul Zofsak]

I recently had a neighbor's rotten tree fall through the fence and into the yard of one of my rentals.  I have asked the property management company to coordinate with the neighbor since the tree was neglected and he is liable.  The management company has replied that they don't coordinate with neighbors and just want me to cover the cost of all the repairs.  Is this an unreasonable request of my property management company, or should I expect them to be able to handle this with my rental's neighbor?
