Holy crap. The truss people just called and said they are delivering the trusses next friday. and i don't have the 2nd floor finished. so i called the lumber company and ordered 120 12' 2x8's and 65 sheets of plywood. i'm going with a standing seem steel roof with the 1x12" pitch and the guy said they didn't recommend pearlings with that shallow of a pitch. so he worked hte math out and said it would be $20 difference to do plywood for the roof under the steel. and it would be more secure. and i can put snow guard under the entire thing for better water proofing. And wood pricing is up 300%, so this is going to cost me.
