Re: tying the porch roof into the main house... I'll add I'd also go with 5/8 CDX ply for the roof sheathing. That added 1/8 goes a long way to resist uplift , and as you know wind in your area is a BIG issue.
Thanks for the replies. The roof is basically flat at present. Is there no way to put some kind of rafter system mounted on the outside perimeter of the mobile home and fasten the metal roof to it. This is just a seasonal trailer that we use in the summer. I don' believe that the weight would be that much of an issue.
