As far as the split pitch, use a roof by extrusion. That will keep the roof as one and make this a smooth transition. Only problem is you don't have the convenience of a footprint roof with the pitch and wall association. But if you design isn't going to change much, then this should work fine. If you do stick with a footprint roof, just use the edit cut profile tool in sections and any detailing tools to help alleviate the visual problem.
Hope this helps.
