The only boots I have ever seen sold for metal roofing. They are rubber with a bendable strip along the bottom that you form around the ridges and flats of the roofing. It is stepped on top and you cut it to the diameter needed

Not going to want to hear it but the pipe extentions, proper rain cap, and cap, PVC you will need to extend the sewer vents and all the roof boots should have been figured out, bought and on site before starting the roof. Not a whole lot of places may stock what your going to need.
If that pipe for the vent is round then you need a mushroom cap.
A rain cap is a piece that goes arounfd the pipe to devert the rain from running down the side of the pipe and getting in under the roof boot.
Metal roof takes a special type of boot a good one will have a metal band around the outside where the screws go. HD and Lowes do not sell them.

I have the boots you are talking about. I also have the stuff for the pvc. Just not the range hood. No one can tell me exactly what I need. I guess I can go get on a roof tomorrow and look.... Hopefully

So is you plan to just install the metal roofing directly over this shingled roof?

What do i need then?

I have the boots that have the metal ring around the base. Just no way to cap it..

And no. I am taking shingles off and new underlayment. Said I was a hillbilly not stupid.

Can't find any pictures so will try to describe it.
That vent needs to come off and you should have a pipe underneath it. You need to match up to that and add an extension to it. Shoot for at least 18" above the roofdeck. You can also get a china cap to mount on top of the new pipe but don't put it on yet.

Install the metal roof, cutting around the pipe doesn't need to be perfect but the base of your flashing (odds are it's a masterflash or oatey, unless it's grey then it's probably a dektite) needs to cover the entire hole. Once roof is installed, Install the flashing with a small bead of urethane caulk (NOT SILICONE) forming it neatly to the contour of the roof. Press snugly on all crotches and install a screw within 5/8" of the crotch. Fasten the rest of the boot approx every 1 1/2" snugging the screws until the boot compresses under it. DO Not overdrive them. It's best to hose clamp and caulk the top of the boot to the pipe. If you don't have one big enough join two together.

Now install your china cap or whatever cap you got on the top of the new pipe and you are done.

Hope this helps

BTW hope your pipe does not span two ribs or you will end up with a dam behind the pipe. Then it gets much more difficult.
