add new shed roof to existing roof

5583 Views 5 Replies 2 Participants Last post by  tinner666
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?

You'll have to explain 'rolled rubber roofing'.

EPDM doesn't get felt.
SBS has anailable base sheet and an inter-ply for adding layers, then it has a cap sheet.
TPO need to be welded.
APP needs to be torched down.
I'm not even familiar with PVC.

You can call my 232 number if you want. I'll be around for a short while.
