I an building my own timberframe and Structural Insulated Panel home in northern Michigan and currently (when the snow and wind lets up) I am putting 1×6 tongue and groove pine on the timberframe for the interior wall finish. The panels are then placed on over this.
My question is on the roof. I am placing the tongue and groove on the roof of the timberframe and I am wondering if there is a proper technique for this? I am concerned about humidity expansion after the home is completed. Has anyone experienced problems with this. My method of attack currently is to place the T&G on the timberframe using 8 or 10 size nails then place a vapor barrier over the T&G then the panels on top of this.
Any input is appreciated

This summer we placed a SIP roof with 6000sq ft of 1.6 pine t and g applied by the factory to the under side of the roof.
Th factory was in Idaho, we in NW Colorado at 8000 ft. The pine was stapled about every foot through the tongue to the overlying OSB. It was quite durable and looked like a million bucks. I fully expected shrinkage, and wasn't disappointed. There were spaces about 1/8-1/4 inch between the boards. But, as I expected them We weren't upset. They still look great. There was no tarpaper between the wood and osb, and can't think of any reason to do so.
