Do we need a warm garage....

I'm scratching my head on this. We get an average snowfall of 6 to 7 feet per year and usually build up a maximum of about 3 feet on the ground. The pole barn roof gets less buildup because of more heating from the sun and it will slide off. My chimney sticks up about 5 feet above the roof surface. I never notice any snow piling up abnormally around it and I've never heard of a chimney affected by snow.

I'm imagining a partially melted/refrozen heavy layer a foot or more thick all sliding off at once?

I can't see it. If it could sit long enough to build that depth why would it slide at all?

My concern is snow accumulation taking out the chimney on the roof. My neighbor down the road had his taken off by snow last winter. He just installed a propane furnace and took the exhaust through the wall. Said he would never go through the roof again. He gave me his wood stove for my new pole barn so now I'm worried about a through the roof chimney. We do get an average of 3-4 foot of snow. Is this a valid concern?

Lots of snow where my grandparents live and chimneys are almost always at the peak of the roof and within arms length... furnace, fireplace, stove tend to be right in the center of the floorplan

A warm up? Same thing that rips eave troughs off houses.

Neighbor at my farm has metal roof on his house. Up about a foot from his eaves are knife looking devices sticking up about 4", a foot apart. They cut the frozen material as it slides down to protect his troughs.

Ok, I did some research and found out that the average snowfall for the Deadwood-Lead SD area is 116". We do have warmups in the early February timeframe.The neighbor did tell me that his chimney started leaking before the snow took it off. I remember his chimney was on the downside of the roof close to the eve. Sounds like it had a bunch of snow/ice on the peak and slid off taking it down?

Your chimney should be reasonably close to the peak of the roof since it needs to extend about 3 feet above the peak. If your stove is not near the center of the building, run your pipe up and elbow horizontally under the ceiling (with proper clearances) to get nearer the peak. Chimneys close to the eaves are not good for several reasons.

My stack is on the back of my house but I have two truss rods that help hold it in place.

The underside warms enough to melt a nice slippery surface. It happens pretty often. People have been killed by it.

It's very easy for me to tell you what's wrong with that setup.
