Roofing is tricky, its all about playing around with extending and retracting the eaves (or overhang part) and the roof sizes for me. Once you get those down you can figure out other little details and tricks.
I kept the concept the same as what you originally had, just made them flow together a little better. For visual appeal I added a few dormer windows with front facing gable triangle roofs. If you don't like those new additions you can easily remove them, just 2 roofs and 2 rooms.
I left the roof pattern on the default one but changed the roof trim.
