Need Help On a Cook Shack Vent Or Smoker Diffuser

I need your guys opinions on a vent for my new smoking hut or smoker ? I had a smaller hut for my Stump's Smoker awhile back and the exhaust escaping the stack going straight up burned the paint off the roof and want to avoid this with the new one . the roof on this one is a lot higher and I tried a flexible aluminum duct and worked but was very flimsy and had to be careful or it wanted to rip easily . I thought about trying a 6" master flow tee just to set on top of the smoker stack making it vent out both sides {like a Lang but bigger} and do you think it would keep the heat from going straight up in one spot or will it do the same thing but burn the paint off in two spots ? I do not want to cut a hole in the roof and vent it that way yet and extend the stack . I know you BBQ brothers can help me out and is the only forum I come to get opinions and answers , thanks in advance .

Do you notice any more draft with that long extension on the exhaust?

cook with it this weekend with it and the stack was burning clean see through smoke and the food was awesome .

What about gutter down spout pipe? It's a little thicker but can be shaped.

that is a great idea but the stack is 6" in diameter and I measured my gutter hole and there is no way it would bend that big unless they make bigger gutters and will look into that :wink:

I am going to buy a metal fan this weekend and hang it from the inner structure and see what happens and thanks for the suggestions . I do not care if the underside gets stained from the smoke just do not want the paint burning off on the bottom and the top like my other one did .

Hang a ceiling fan & run it on high

thanks for the suggestion buddy , I bought a metal fan and hung it from the ceiling and it seemed to do the trick and the roof never got hot .
