Hi, I am working on a backwoods cabin in Vermont. Its 16 by 10 and a shed roof (single slope). I was thinking about having the woodstove come out on the lower back side. The roof extends out about a foot foot maybe two it also does that on the sides.

I'm installing an Ashley stove from probably the mid 2000s looks like a Home Depot 6 inch piping going to Duravent through wall kit with class a pipe coming out the top.

My issue is I think the roof is extending farther than what my wall kit will allow based on a YouTube video that I saw. Can somebody send me a link to a part that will allow me to extend the tee about a foot or two off the building so I can get it around the roof clearing it by 3 inches, whatever comes through the building needs to be insulated, I am happy to build a special bracket to support the tee and all that but mainly looking for the special pipe to allow me to extend the box outside the building not sure if that's common thing people have seen or done.

Also looking for feedback on the roof support going to a metal roof. I just have regular metal roofing panels and I'm putting the roof on next week and was planning to try to do the stove at the same time and was wondering what people think or do adding roof support for the stove pipe and drilling into the metal roof Perhaps if the supports are drilled in towards the outside the building, it isn't as big of a deal because it would just drip down outside. Im hesitant to drill into my metal roof maybe use liquid nails for the support?
 
It will needcustom bracket extensions or notch the soffit to clear the pipe by at least 2". Or better yet, go straight up through the roof. This usually costs less and works better.
 
Thanks. The issue with the bracket extension is the pipe that goes through the wall is not that long its like 8" and I have 2x6 walls with metal roofing on the outside and inside as the skin. It would be great if I could get a replacement pipe that was 2-3" and then that bracket would work well.

Someone told me today instead of the bracket do 30 degree adapter things to tilt the pipe when going vertical and that will give it run. I found one for $200 on ebay that I might do but also a little concerned it wont give me enough clearance as well. Would 30 degree elbow give me 1-2 feet of run on a 3' pipe I doesnt seem like it. And even so I wont be able to go that high with out needing a brace that is drilled through the roof.

Leaning on trying the 30 elbow and seeing if that is good enough to get around the eve and go up 3 feet or so.
 
Try to find the manual for the Duravent system you're looking at. I think it includes a lookup table for the 30deg kit so you know if it'll buy enough distance from the roof's edge.

Our chimney was installed sticking further out the house. We wish we had used the standard brackets close to the house, with the 30deg kit to get around the roof.
 
Duravent does not allow exterior elbows. Lots of people still do it but for some reason they say you are not allowed to do it
 
Interesting, so those 30deg offsets are only supposed to be used in attics & the like?
Yes. There are companies that allow their use outside. Just not Duravent. I don't think Selkirk does either. I don't get it but thought I should mention it
