Last winter a heavy snow slid off the roof of my guest cabin (friends & family only ) and tore off the stove pipe. After all these years, it got taken out. I patched the roof and am now trying to source replacement stove pipe pieces, and I could use some help with identifying the specific pieces I need. I live >2 hours from any stores that carry this stuff so I would like to shop with advance knowledge of what I need and return home with all the right pieces. I do not want to remove the stack support piece that is in the ceiling. This stove will not ever be used on a regular basis, but I need it to be functional. As you can see from the pics, everything's 'good enough' up to the elbow that enters the chimney support box. I'd like help identifying the pieces I need to run up thru that box and get up to my cap. The damaged piece I removed had a flange at the bottom, which I think attached to the inside of the support box. This ran through the roof and joined another piece of single wall, then the cap. There was also a storm collar, and another piece that had a big flange that slid under the roofing metal. I've seen the storm collars and the roof flashing at the big box stores. What has eluded me is the piece I need to go from that elbow inside my cabin up through the roof. I would love to get this completed before the snow flies (October 31), and I've finally got time to begin my research. And I'm damn sure going to install one of those vee shaped snow guards on my roof. Thanks!
