I am adding a new shed roof over my 20x20' concrete deck. Is the proper way to run say a 2x8 across the 20 ' span and attach 2x6 rafters from the piece of wood? I was only going to support the roof from the outside walls (no center supports) - is that OK? What should the span be between each of the rafters?
Obviously I need your help which I really appreciate.
Thank you,
Chuck

new roof addition to existing roof

Thanks for your reply.
I apologize for not being more exact on what I was thinking about going.
I was going to put 4x4 posts around the front and sides of the shed roof say every 4 feet to support the rest of the roof. I was concerned that being I would have no supports in the center of the span if that would be a problem?
Thank you,
Chuck

adding a new shed roof

Thank you very much.
Fortunately I am in Atlanta so we do not get a lot of snow here. I was thinking about using the rolled rubber roofing. What do you think? If I used rolled rubber do I have to put felt paper under it?
