Leatherface Tree

I am a senior citizen and also a care-giver for the lady of the house on Woodcrest. On the morning of Aug. 14 I heard a loud bang that shook the home, and then more heavy reverberations to the roof. At that time I was in the back of the house and did not understand what was shaking this home. I went outside and witnessed a man on the roof cutting large limbs and pushing them off the side of the house, I asked why he was on the house and what was he doing--he replied that he knocked on the door and rang the door bell without a response.
I told him that if there was damage to the roof he would pay for it. His reply was "I'm not paying for anything--my wife is a lawyer." "You are in my way." As I understand the law he is trespassing. I did not give him permission to get on my roof.
It's obvious that he thinks he can do whatever he wants to any home adjacent to his job site. We will have a roofer inspect the damage and go from there to whatever we need for justice.
