garage expansion

Currently have a detached two car garage with a peaked roof gable end on front and back, want to build a second garage attached to side with living quarters above. New garage would be higher but long like the existing, what kind of roof line would be needed on new garage and how would I tie into an existing lower roof?

You can do what you want on the new addition's roof, as it won't be tied into the existing garage roof (being close to 9' higher in elevation, to accommodate the living quarters). I'd do the addition's roof with gabled ends as well, so the addition doesn't look so much like an "add-on." You will need to build a transition between the old gable and the new addition's adjacent wall, like an over-sized cricket and perpendicular to the garage roof gable line, to prevent heavy runoff from being dumped against the new wall.

Which way does the roof line run?
Any I've seen built like that where the wall meets old roof line on the low side of the roof almost always leak at the valley. It's called a dead valley. If you built the suggested cricket as a gable roof not a shed style roof it will look better and the water will have a place to run off.

put a gable on the new. same direction. carry the roof line of the existing gable, the side away from the addition, up to the wall of the addition, provided the wall is tall enough. It would then look like a shed roof from the end..
