Followup on the shop furnace installation thread:
The chimney is now in place. I have a friend who's a roofer and the tricky part is flashing this into a steel roof with all the convolutions, etc. - and I didn't want leaks!
Buster slid a new piece of sheeting from the eve to the center of the stack and then overlapped the SS boot with the original sheet from the peak to the stack. With some foam sealant and other roofer tricks all seems good. Pics to follow.
When Buster was up there I had him look for leaks as I had a drip right over the hoist bay. Turns out that the original installer (I hired guys to do the siding & roofing) had overtightened all the screws with their built-in neoprene washers. If you do that the seal squishes out and the Sun can deteriorate it, which mine had. The quick solution is to replace all the screws and not overtighten them. To be on the safe side, the guys used a commercial caulking and put a dollop under each screw and then run in the new screw. We had a serious rainstorm tonight and all looks good but of course we won't know until a few years pass. So I had two guys screwing on my roof for two days - but I'm very liberal and didn't care.
Those of you with pole barns need to be aware of this! I was certainly clueless.
