We’ve been using a product called American Roof Brite for years with amazing results. I don’t have the web address handy but I’m sure you could google it.

*edit- don’t use anything containing bleach!

Water & TSP (trisodium Phosphate), and a good stiff broom.

Agreed.

TSP is available at the local Home Depot or Ace Hardware Store in a powder form and just follow the directions for mixing ratios.
