The old 3-tab composite asphalt shingle on the lower roof is off. We found five layers of this stuff, and the recommended maximum is two before you're supposed to strip it all and start over. One layer or a dozen, it doesn't matter for this project because we're installing metal roofing and we need a bare roof on which to mount it. Metal has a much longer life, is lighter, and has better heat reflectivity than asphalt.
