I'm designing a garage for my backyard and I want to obscure my view as little as possible. I've read that asphalt shingles aren't great on a 2:12 slope, so I'm just planning on using metal roofing. This should be adequate right?
As for installation, I'm planning on felting the entire roof, sealing the edges where one piece meets the other with roofing tar, then screwing the whole thing down. Is this appropriate?
I live in Alberta, so snow is a given. Also, the garage won't be insulated or heated.
