Well I roofed today...and had a blast! After four days in a row of nailing shingles on old, splitting plank decking, I finally got to nail on plywood! Got to love the nail gun!!! Ten squares in ~5 hours, by myself, including toting shingles up, some felting, and chalking lines, which is time-consuming when working alone. Should finish up tomorrow.....It ain't tree work, but it pays the bills.
