Metals a good choice with Midwest winds. I'm constantly picking up shingles and siliconing where they once were.
Are going to put any of those ice breaker thingy's on there so a whole sheet doesn't come sliding down at once?
Metal roof started but not finished

You betchaI like the looks of your cedar porch supports. I assume you are going to build cedar collars to cover those hideous metal ties though!!:D
What are the black things the posts are sitting up on ?? I assume they are to keep posts up off the porch floor ( water )??
