Roof cleaning help

Could someone tell me how I can clean a shingle roof with a 4gpm 4,000psi pressure washer. I’m just starting out and need some advice. I know NOT to use high pressure but what tools/attachments do I use. I have a downstream injector. Thanks in advance!

Tons of good roof cleaning posts on here. Use the search bar.
