Best way to seal new Chimney through Metal Roofing


I am going to install another wood burning stove in the family room and before I start what would be the best way to seal the pipe going through the Metal Roofing. It is 32" wide Alum sheets on the roof. I have done chimney installs on shingled roof before but not sure how to get a good seal on the metal roof.

Flexible roofing boot with proper sealant. I take it this is in a spot where snow will not bother enough to need a cricket.

I have not decided how far from the peak the Chimney will come out so I may need a snow shield. What brand of flex boot would you recommend and also what would be the best sealant?

Here are examples of various methods. I only use sealants/caulks to provide seperation between the sheets to disrupt capilary action.
I've seen those boots, but never found a use for them yet.

Thanks Keith.
I will have to find out who sells the Dektite in BC. They look like the best sealing products I have seen.
