So many people do not use an extension ladder correctly. I first observed the issue when I was a kid. Everyone who got on a roof raised the extension ladder until the top of it was at most 1 rung beyond the gutter. Then they went up, and crawled over the top of the ladder onto the roof. To get back down, they sort of went on all fours, stuck a foot over and down the top of the ladder, and felt around blindly for a rung. Then they backed over and down. Looked real clumsy and risky to me.
I thought this was stupid. Why not extend the ladder further, like 4 rungs or so beyond the gutter. Then when your feet reach the rung even with, or just below the gutter, step sideways and up onto the roof with the other foot. Hold onto the projecting ladder to steady oneself. To return, just turn around backward and step off the roof onto the ladder.
I suggested it, and was told to shut up, what did I know about ladders!
So when I had my own house, and my own ladder, my way is the way I did it. Not scary at all. Many years later, I saw it described in a magazine as the proper method. Still see people doing it wrong.
Old habits die hard... literally?
