Roof Cleaning- Wire brush method..Which one do you apply?

I really prefer using wire brushes to remove moss. Its really effective in removing moss along edges and seams of the roof shingle with removing as many roof granules like pressure washers would. I use a leaf blower once all of the moss is detached. Then treat roof lastly to help slow moss from coming back.

do you ever use a scraper to get the moss off first then wire brush and blow?
