Roofing experts, this pic is from 1969L88's posting about his new meeting place located in Kentucky. How is it that this structure can get away with the rafters running horizontally and fully insulated. There is no way this set up is vented as has been discussed in this thread. Will not there be a moisture issue? Or is it a none issue becuase of the metal roof? Kentucky still gets cold enough weather I'm sure does it not?
