I have notched the plywood roofing inbetween the rafters say, a 10" by 2 "
slot near the top inbetween the rafters, and then use a cora ridge strip
vent. The roof is shingled to the slot at the top. The strip vent is placed
at the lower edge of the slot on top of the shingles. I use Henry's or roof
seal on the bottom of the strip vent. This is nailed into the roof. then I
put a nice bead of Henry's or roof cement to the top of the strip vent and
place the next shingles on top of the strip vent. You have a 1" vent system
built into the roof at the top. they make a commercial plastic application
of this for the lower or bottom of the roof and that also could be used....
