I have enjoyed reading forums and would like to ask a roofing question.
I am building a garden shed with taper sawn 18″ cedar shakes roof on skip sheathing. My wife objects to tar paper that would be visible if I follow instructions on cedar bureau’s web page for recommended 7.5″ exposure. Would it be ok if I apply shakes in triple ply fashion with 5.5 or 6 ” exposure without the tar paper. I have spent a lot of effort on this shed and would hate to see it wasted by a leaking roof because of a lack of tar paper.
