Well this thread came along at the right time. I plan on cleaning the chimney this weekend. My normal process is to go out the bedroom window onto the porch roof, climb up the steep part next to the dormer onto the 4/12 pitch back roof, then climb onto the top of the chimney and drop old tire chain ball on the end of a rope down the chimney. I’ve never been afraid of heights and feel confident in my abilities, but since I broke my leg when the fifth rung broke on the ladder this summer, I’m rethinking things. I am considering a rope but tying it to the truck never came to mind!
