I have cleaned roofs with lichen before. I sprayed on the roof mix, let in dwell, spray another coat, lightly brush to remove the solids, then rinse. You will usually have bald spots where the lichen ate away the limesone granules. And by the way I don't believe you need 10 years experience to be a good roof cleaner and powerwash company. I do allright with only 4 years in business and a good education. I have good teachers. This board and good decisions made a big difference. Low ball Larry walked me through my first tile roof job. Thanks Larry. If this guys methods are more expensive or just different so be it. It may be worth it to try out. I say post it. It might replace the current methods or add to our techniques.

You HAVE to use pressure out there, the Moss will spread the shingles open if you dont do something.
You CAN kill the Moss, but it is no easy to remove w/o a LITTLE flow/pressure
