Having trouble recreating L shaped Roof with 3 diff styles, Gable, Half-hip, hip

[juan23]

I'm experiencing difficulty putting together three roof styles attached to each other in and L shaped roof. Anyone with ideas on what I might be doing wrong? My album has a partial pic of the front building, if you're inclined to help. Thanks in advance.

could you be a bit more descriptive? I'm not sure what you are wanting to do.
