Note to JC:
Go ahead and order the trusses prebuilt. It’s not really that expensive and you can then have the whole roof trussed, sheeted and tarpapered in one day easily. You can then shingle it the next day. You will save so much time.
P.S. do not forget to use plywood spacers on the sheeting ...
P.S.S. do not forget to double up on the hurricane straps either. I would put one on each end of each truss despite code not requiring that many. They are cheap and as they say “when in doubt, build it stout”. ...
