Shed roof problems

[freebird_wr]

Hello,

I am trying to fix the shed roofs on my plans for my front porch and back porches, but I seem to be creating more problems than I solve. The back shed roof is cutting into my ceiling in my nook and family room. Can anyone take a look at my plans to see where I am going wrong? I am beginning to pull what little hair I have out. Thanks a bunch. Scott
