Ive got a roof that Im trying to estimate, but am having a hard time figuring out how I can clean it. The house is 4000 sqft, 2 story tile, but it doesnt have a front, back or side yards. It backs up to a marina parking lot, with a 10 ft drop. The driveway is pavestone, and cant handle the weight of a giant boom. Theres no place for ladders to set up, except in the front and the roof is too steep to walk. The only logical thing I could think of is to get a 90' boom, but nobody around here has a 90' articulating boom and from the angles we would be at a straight boom wouldnt work.
. The ony other thing I could think of is hang in by a crane
. I can get some pictures if need be, but I just need some advise! Hope this makes sense.
