I'm with Hoodoo, I did a tear-off of my house and garage roof, and though I didn't cut any shingles, the paper and ice shield saw a good bit of attention from my DWMS. I also had to use it (it was the closest thing I could get my hands on up on the ladder) to pry loose some aluminum gutters and cut around a small number of pop rivets holding them together. Also used it as a piton several times to stand on while clambering around on a 12/12 pitch board-construction (not plywood) stripped roof. It saw some garage use to cut off several coolant hoses from their aluminum outlets while getting my car winter-ized.
Used the SHII to cut through some PVC plumbing, and to "de-construct" some kitchen base cabinet guts to install sets of slider-shelves. Also to help chop/dig out a stump from the front yard, with its share of rocks and clay, resulting in a few small nicks that disappeared after some time on the Sharpmaker.
