OK been asked a few times about roof cleaning, now I don't want to go climbing all over someones roof, so I have come up with a plan I would like to run past you all. Already have a 7.3 meter I think it is? somewhere around 7-8 meters anyway long reach telescopic pressure washing pole, there is a wall cleaning rotary wall cleaner attachment available for this. Could I put a scaffold tower on the side of the house and use the wall rotary on the end of the pole to clean a roof with? Seems totally feasible to me as they sell a roof cleaner which is essentially a rotary on wheels with a rope to wind it up and down the roof, so can see this as being pretty much the same thing only maybe a bit smaller, so may well take awhile? Thoughts on this would be most appreciated.
