Thinking about it the places I've seen OSB have been in places that aren't stress places. Above both A/C is the sofa. Above the drive shaft is the bed and this landing there is no weight on it. I don't know but have not had much problem with it. Am I wrong here? I don't really know, but I own a number of houses and seem to have one roofed every several year. I am getting ready to have my own house roofed and talked to him about putting plywood rather than OSB. It will be the same price, but he liked OSB because it lays flatter, so we are putting down OSB. OSB weights little more. I've noticed that lot of decking now they are using is 1X6 tongue and grove. They say it is cheaper but a little more labor cost. Chappell
