So this is a photo of my metal roof. Except on the other side is the old wood stove pipe that is coming out. Both sides are identical. I want to replace it with another identical piece. My questions are: Do i just unscrew the old one and replace it with the new one the same way? It's there a rubber gasket or any caulking on the ends that cover each other? How hard is it for me to get it back under that top trim piece that goes all along the top. Is it OK for me to cover the hole from the inside and then just put the metal roof over it? Any help is greatly appreciated submitted by /u/CanAmFanboy [link] [comments]
