What's everyone using for there wood stoves ..I've seen those rubber boots on line that fit a variety of chimney sizes and cut to fit..with dead soft aluminum around the base that can be moulded to the profile of the metal roof and then caulked and screwed to the roof...you can buy just the boot or they sell a kit with brackets and a storm collar..or if you have other ideas lets hear them....using fully insulated chimney through roof or just double wall stove pipe?I don't need certified or anything..no insurance...just something that will keep the water out

It is hard to beat the rubber/silicone boot and dead soft alum for ease of install and weathertightness. We have several on a couple buildings; chimneys and plumbing vents.

None of the above. I used a thimble. I didn't have the skill to ensure a waterproof roof around a chimney so I didn't fart around with it. I used a through the wall type chimney with a T corner above the stove, the thimble is triple wall insulated around the connector and includes a heat shield for the stove pipe. outside is another T connection that leads to insulated chimney going up along the wall. its more expensive as it requires more insulated chimney sections than a roof type, but I only have to unscrew and open the ends of the T sections to run a brush up any part of it so its easy to clean and since it was through the wall there was no messing with the roof.

My only concern was the temp of the pipe on the Rubber..it would be about 8 9 feet above stove..i have no clue how hot these get as I've only used chimney and single wall..but I'm looking for cost savings compared to using chimney id love to just go double wall right out the roof..

I'm using one of these:

Is it a Canada-only thing? Do these guys have a patent on this flashing design? All I can say is that it works great on my 6:12 pitched roof.

Wood stoves generally perform better if the stove pipe goes straight up and through the roof rather than going out the wall and then up (better airflow). Plus the secondary heat from the pipe can warm the inside of the cabin.

If I understand you correctly, you are considering running single wall stove pipe from the stove up thru the roof. That will work fine, but you'll need to keep all combustible materials at least 18" away...AT LEAST! Single wall pipe radiates a lot of heat when the stove is going good. If you use it, you need to make sure you provide a proper race if you're going thru an attic space. You could frame up a large opening and line it with metal, for instance. One benefit would be capturing even more heat inside the living space. If you go out the roof near the top, its easy to seal the upper end of a metal roof jack by slipping it under the ridge cap on a metal roof.

I'm using the same thing joeyrf is using, then you tighten a skirt around the chimney above it that diverts the water about 3" off the chimney. Both are then coated in high temp silicone where they meet the chimney.

Davey,
When you say double wall stovepipe, do you mean class A (insulated) stainless chimney pipe or just double wall stovepipe. There is a big difference. You should only use class A for the top that goes through the roof. I just ordered a silicone boot with the dead soft aluminum ring around it from dynamic fasteners. I'll be installing it over an 8' class A chimney next weekend. I'll let you know it goes.

Heres an update..i used double wall to class a insulated through the roof...the rubber boot i have actually goes around a clearance shield i have that creates a 1 inch space all around the class a..so the rubber does not get hot only warm..the class a actually does get warm not hot as well... i didnt think it would be hot at all..but with the extra shield around the class the rubber is ok..not sure if id actually have it tight right around the class a though..might get a bit too hot
