Your home's chimney set is at the highest point of your home which makes it very vulnerable to damage. It is always a good idea to have your chimney inspected when you have your roof replaced. In this situation, when we were performing a routine inspection on this home we noticed rotting issues with the siding. It was also observed that the chimney chase contained no subsiding sheathing such as plywood or OSB. The framing members were also found to be improper for the height of the chimney.
