Can I install a ridge vent on simple truss shed roof (no ridge beam)?
Your plan to cut back the roof sheathing back 1&quot; on either side of the ridge is the way it is done whether the roof is truss or conventional, framed with a ridge pole.
I have seen formed aluminum ridge caps used over this cutout or the fiber mat that allows the regular shingles used for the caps to cover over the matting. The angle of the roof will accommodate either.
When you cut back the sheathing, it really wont be sharp anymore, there will be 3 peaks, 2 of the plywood, 1 of the framing. The only sharp part will be at the ends, if you choose to leave 1' of the sheathing intact for weather proofing at the ends.
