I don't Believe that the weight of plywood or OSB will be an issue, but if you are concerned about the extra fat, you are able to normally seek the advice of an engineer.
Q. "Do you think you're declaring that raising ventilation to that 2nd Tale attic would basically be a foul strategy, if we carry on the foam about the whole next story gable roof, and rather we should always help it become totally unvented?"
At last (I guarantee This really is my final roofing company for sale subject matter). Pertaining to my fiberglass batts: Will the struggling with that comes with it retard the drying out system that I described over (will it make any difference what side I place it on within the purlin cavity?
