roof will not build

[Reiter]

I have been trying for over two days to put a roof over a porch. I have even removed the porch and created a room and called it a bedroom with all the roof directives entered and build roof over this room turned on and turned on the build roof. The system will not build a roof over this room. the room does turn shaded when I click on it so I know it is seeing it as a room. I have watched the roof over build video and many other roof training videos. The rendering below is of some manual roof planes just placed to give you an idea of what I'm trying to create. The trouble with the manual building is many things are not lining up and so far I havent found any of the fixes for those problems either. I'm a rookie so any explanations will need to be entry level. please dont assume I know where anything is because I clearly do not.
