So, I popped off my chase cover this weekend to have a look at what I was up against in building the alcove for my BK. Whoever did the siding job on my house (before I moved in) left a small hole in the siding where the chase meets the high part of the roof. Should have been flashed, but noooo.. & since it's a wood frame chase.. yes, water damage. One whole side of the chase is rotted completely through from the roof to the ceiling level fireblock. Won't know how far down it goes till I take out the ZC fireplace. Good thing I decided to do this project when I did before the spring rains, little more time and the water would be flowing into the house.. Fun, fun, fun...
