I am planning to replace my old asphalt shingles with red cedar shakes. One builder recommended drilling holes in the existing sheathing to allow for ventilation. I want to have a solution that will solve a moisture problem I have in my attic, so have avoided a “cedar breather” style product. My question is whether drilling holes is sufficient to provide the ventilation necessary for the shakes. The other option I was considering was to rip-saw a series of horizontal cuts and remove sections of the sheathing, which would effectively leave me with a skip-sheathed roof. Any advice is appreciated.

Not to be too nosy; but why in the world do you want several thousand pounds of tinder on your roof? In fact in several communities I'm aware of shakes are a no-no due to the fire hazard.
*I've seen furring strips or purlins installed over sheathing and cedar shingles installed over them. I was never real clear on how the air circulated up the roof from eave to ridge since the purlins are perpendicular to that and the rake was closed tight. Maybe it would be easier to rip off the sheathing and install purlins than to make all those rips. Would expose roof directly to attic air. Also reduce dead load, if you care.I assume the same techniques could be used with shakes.Try http://www.cedarbureau.com
