Sheathing under metal roof
I Goggled this question, what lead me to this website. I read about this same topic here, I believe it was from 2012, however, the same question but for a house not a shed.
My main concern was sheathing thickness, but will take in all anyone can offer. I am a home owner operating as GC, while using Contractors to build a two-story 30x30 addition over a poured concrete basement. In matching the materials used on the existing structure and area, I am using a Metal Roof and for my upcoming meeting with the County, I want to have my "Typical Wall Section" sheet filled out as accurately as possible...in includes "Sheathing in Inches". I'm using 2x6 (exterior)wall studs, 16"oc, and was planning on using the same (2x6) for Rafters; although I saw 2x12 suggested in the 2012 thread (???). The house, in N. VA is about 1600ft above sea level, windy and very cold, therefore, thicker walls, more insulation...etc. We can get as much as 25-30 inches of snow up here. All that said, Thickness of Sheathing (??) and as I said, any/all information is a huge bonus. Many Thanks, pt
