Since your roof is earth toned, with a kind of a rust undertone, and the brick with a gold / dijon then a teal gray is going to be warm enough to connect to the yellow undertones but muted enough to be a contrast. It will be modern, but also evoke a cottage feel - look at http://www.benjaminmoore.com/en-us/paint-color/knoxvillegray#ce_s=knoxvil

for the garage door and trim, match the brick like you did on the shutters last time.

This time, on the shutters, go deeper - look at new providence navy - also a teal navy http://www.benjaminmoore.com/en-us/paint-color/newprovidencenavy#ce_s=navy
and on the front door, a cottage touch this beautiful muted blue green

This will work with the roof now but allow you to get a charcoal toned roof which will give you the most flexibility in the long run about color.

Stay away from white with the warm roof.
