roof corners

Hi Everyone, I hd this roof extension put on over a patio but did not realize how wierd it would look at this North East corner of the exisiting roof. Any suggestions on how to fix this? It is the complex angles at the corner that is killing me!! Thanks, DAVE

Can anyone tell me if this is normal to have the roof shingles hang off this way after installling hardie lap siding? It seems to me that they should sit flush to the very end of the siding. Will this likely cause any damage to the shingles?

I don't know what I'm doing, but my husband and carpenter do. They are having trouble with figuring out how to feather the angle though. The roof is steeper on one side of the porch. Should they feather it in the front by shimming 1/4" at a time or should they break it up on both sides? I'm just...
