A guy down the road DIY'd his steel roof. Measured the exact size and had the panels cut. You don't often think "hey, nice roof", but his is beautiful. I would consider a metal roof on the front slope and above the sunporch.

I wouldn't do metal on the back part of the roof... it's too expensive to justify on an area that you can't see from any angle. Plus, it's so slippery, and I have to be up there a few times a year.
