This is what I did for my client who's vinyl siding was melted by these bay windows of the house next to him. I took pictures. I went over to the neighbor and found out who his insurance carrier was. I contacted the insurance company and forced the neighbor's insurance pay the damage and force the neighbor to put a shield or covering on the windows. My client had to pay zero and had no claims filed on his policy. My client loves me and has referred me to 10 of his friends because I went to bat for him. The insurance company saw the pictures I sent him, saw that the huge bay windows did indeed cause the damage. That company knew they had to pay. They replaced the siding and the neighbor had a company put a type of shade film on the window that took the glare off of my client's home.
