I used to climb on frosted sloping roofs back in the 90s/early 2000s as well as flat roofs.when I look back at the chances I took just to clean an upper window when on the ladders it's absolutely madness to keep doing it now when you have WFP....
I was just honest and told my customers I'm not prepared to climb ladders anymore due to a window cleaner (who I used to work for) falling off and badly injuring himself at 76....it made me think...
I only had 4 jobs left where I had to use my ladders to reach some set back windows or glass roof....
It's a great feeling going to work knowing I'm not gonna have to climb on a roof ever again!
