Just purchased and installed HD Suite 2020. Is it possible to design a shed roof over a walkaround porch that extends down one side of the house? I’ve been able to get a roof over the house that’s okay for the most part but it’s mounting the roof all the way out over the porch on a 12/12 pitch when I really would rather have a 3/12 over the porch and then start the main roof from there.
