Got the roof plan sorted I think...
Talked to a buddy of mine who has been a general contractor for the last 40 years and basically has a private lumberyard (has been buying bulk material for years by the trailer load for dirt cheap because it was odds and ends..)
Anyways... he owes me a favor or 2.. so he stopped by and helped me layout the roof design and offered up the majority of the materials that I don't already have. Here's the plan...
The main bows will be cut from 1x6s... set 16oc. They will be ~2" higher in the center then on the outer edges and they will be notched to saddle the walls instead of just riding on them flat. The bows will be tied together via 1x2s on edge every 10-12". Roof will then be skinned with 1/4" marine ply, glued and screwed, with the seams and edges glassed/sanded... then a few coats of epoxy topped with Gacoroof silicone roll on.
Reason for going with ply is availability in my area. If I find something different before I get the skin material.. I may go that route instead.
Anyways... once the roof it built, it will be fully insulated either using foam or fiberglass... what ever I can get my hands on that has a decent R value and is reasonably priced.
Doing it this way, all I'll have in it cost wise is the skin material and coatings.
Sound like a reasonable plan?
