Cold roof design for existing structure
I have an early post and beam house renovation underway. All exterior walls are the finish interior. I am installing Blums skin then skinning walls with 1” ridged insulation, then layer of ½” zip wall then clapboards. Roof will be layered using ½” ply, taped, vapor / air barrier, 1” ridged insulation taped, roof underlayment, strapping then zip roof, underlayment and slate roof. Obviously not going for high r value due to numerous other constraints. This is a guest house used primarily for 3 seasons. I would appreciate any constructive thoughts or advice.
