insulation and wood shingles

I just completed an adddition on my house which includes a cedar shingle roof on 1x4 skip sheathing. I'm getting ready to insulate the roof which has double 2x8s. I was planning to use the fiberglass batts and have 2 questions. First, do i need to do anything to insure good air circulation (i can't add any vents) other than leaving a 2" pocket just below the sheathing. Also, what should be done regarding a vapor barrier ? Thanks

Vapor barrier toward the heated side (inside).

Ventilation helps any roof last longer.

If you are in a cold, snowy climate, you could be asking for a lot of trouble with no additional venting. You may not see leaks but you can get wet insulation that does not dry out.

Thanks
I'll see what I can think of, maybe leave some breathing room at the fascia board

would it make sense to put some sort of vapor barrier on the top side of the insulation as well ?
