^^^ yep...but still alive.
A few years back, I had to do some work on the steepest pitch of my roof. I needed both hands for the work, so I took two 12ft 2X4' and joined them for a total of almost 24 ft. I nailed stepping cleats to it and a one foot lip at the top. I slid it up the roof on it's smooth side and flipped it over so the lip was over the peak.
I could then easily walk up to the work area and didn't have to hang onto anything.
