You need to keep an airgap. Typical job would require a ridgevent and
eave vents with special cardboard or foam inserts above the insulation so
the air can flow and keep the shingles a bit cooler and moisture a place
to go.

I have a question about venting a garage roof.
I am turning my detached garage into a woodworking shop. I am adding
heat
and ac and will thus insulate. I know that a building with an attic
space
needs to be vented. However, can I insulate right onto the roof, in
other
words, put the insulation right between the joists and right up against
the
roof sheeting? Or do I need to make an attic space and vent the roof?
Thanks
Rob
