We showed up to a roof cleaning today in Ocean Pines, and this was the reason the lady called. They had a guest bedroom window that overlooked this attempt at a roof cleaning! The damage had been done, but we were able to remove all of the swoosh marks so that you couldn't tell it had been pressurewashed.. 3rd roof this week where we have seen pressure washer marks!

Why don't you try a professional roof washer. So it doesn't damage your roof.
