I have no experience in timber framing, although I have experience in other contruction.
I am planning to build a small post and beam barn (more like a large shed). I was thinking of using wood shingles or shakes for the roofing. Pictures I have seen, show 1x4 as the nailers attached to the rafters. I am concerned about this. In a conventional roof, roof sheathing prevents the roof from "sliding" or collapsing. I don't see how this works in the pictures I have seen.
Any one can explain this to me?
thanks
Jonathan
