i used to use long ladder andplace it over porch thenSTAND ON PORCH ROOF,HOLD SILL AND CLEAN ONE HANDED,i dont really think thiss is very good advice tho
Still have two houses that I do that way, I'm always afraid someone sees me doing it lol. Kinda cowboyish.
It's not a porch, but it's a tiny little angled roof. Put ladder up, with laddermatrix. Ladder rests on brickwork above window, when I get near, I step off the ladder and on the roof, and grab the sill.
For the topic starter. Get an Unger 20' pole. Will last you ages, and you can easily upgrade it to a wfp.
