Whether you want a double gable roof with 6 pyramid shaped dormers or a simple gambrel roof the basics remain the same.
Revit roof convertin.
However the best method to generate native revit elements from rhino is to use the wall by face roof by face curtain system and or mass floors commands.
Convert a hosted family to face based or non hosted family this is a short excerpt from revit.
