I am adding a room addition on my house. I am using trusses 16" on center 5-12 pitch and decking it using 1/2 OSB. I was going to roll felt paper on the sheeting and then install 29 Ga. painted steel roofing. I was told by a few people that i must run stringers on top of the feltpaper 3 feet apart the length of the roof and screw the steel to it?
Can anyone with experience tell me if my method will work? I have the foam that you put on top under the ridge cap and under the steel at the bottom.
Please help ASAP, Thank you
