Thanks Juan, we really wanted a light roof from the beginning (surf mist or shale grey) and built the rest of the selections around that. We ended up with shale grey with austral grange bricks and basalt facias and gutters.
Good luck with finding a builder, that was the hardest part for us. Don't forget to play them off each other (within reason) as much as you can to make sure you get the best deal for YOU - not the salesman. Don't feel sorry for the sales people for hassling them with what you think are silly questions and definitely don't let them talk you into something your not 100% sure on! As hard and arduous as it is, it is extremely satisfying finally signing on the dotted line once you've made a decision! Good luck.
