Hip roof insulation
Have read your commentary about insulating an attic with hip roof. You recommend a sealed condition attic, ie. spay foam.
Am building a 10’x10′ closet in attic under a hip ridge; 8 pitch roof 2×6 rafters, 1/2″ plywood sheeting. If insulation is stuffed between the rafters I understand the risks you describe with the sheeting damage because of possibility of trapped moistures as the rafters are attached to the hip ridge that won’t allow venting. I would ask, could this simply be avoided by painting the underside of the sheeting with a good oil based primer or paint. And so what if moisture is there with inadequate ventilation.
Understand your solution is the closed cell spay foam, but would like to avoid that expense on this type of small project.
Thanks or your time and would appreciate any comment.
have attached a pic, it was a start but understand I may need to redo things
