Hello, first post here and I am on mobile so sorry if this is the wrong location to post. I am getting ready to reroof my house and my current flashing is not likely savable. It is a giant mess of roofing tar. I went to the local Menards thinking all I needed was a 8"ID flashing and storm collar. However upon doing a test fit and more measuring i find out that my pipe is 11" OD vs what seems to be a standard 10" OD. It will not fit at all. I cant find any branding on the chimney as its all been painted, poorly. It appears to be triple wall and uninsulated. Does anyone have any ideas on a flashing i could buy for this? Im set to do the roof next week besides this
 
Update, i was able to find that it is amerivent 8fb chimney pipe. Unfortunately i cant really find anything for it. All amerivent shows is a 10fb
 
After looking at it more I am just going to replace it all with the selkirk brand from Menards. The 11" pipe says 4" min from combustibles. It looks like it has maybe an inch and a half. Obviously it was fine for years before i moved in but I cant sleep well if I just leave it.

Good choice
 
4” clearance? That’s a first for me. Replacing that may be the best choice you make for a while!
 
Yes indeed. I can find nothing on this pipe online at all. Im not sure its even rated for woodstove use. Does anyone know what UL 123J standard is? I can't even find this on the UL website but thats whats stamped on the pipe. Its Amerivent 8FB. I went out and bought some selkirk supervent to redo the entire section above the ceiling support and bought an insulation shield as that was missing as well. Plan to install this all when I do the roof. This whole house kinda seems like it was owned by a hack. Ive been finding so many little things that were done wrong. There's an office type room that was added on, I kid you not it has 2x4 floor joists and mdf subfloor.
