I'm with Bob on this one! I clean my roof usually twice a year and all I do is use a medium brush and some Blue Dawn in a bucket of water. If something is a little more difficult to remove like tree sap and the like I just go over it again and concentrate on that spot/s. I only wash about a 4' section at a time and hose it off right away so the soap does not dry on it. Afterwards, I wash down the whole unit using the same formula of soap and water. I always check all of the caulking around the vents, skylights and etc and if needed recaulk those area that are needed. Don't fall for those products that say they protect your roof and etc. It's a waste of money!
