First roof wash for Elite. Mix was 15gal water/10gal 12.5% bleeeeeach mixed in 25gal tank on my iddy biddy trailer and applied using 1.8gpm/60psi sure flow. Let dwell for about 25 minutes. Rinsed off with 4gpm washer with #20 40degree tip. Customer is real happy. The darker areas above the garage are tree shadows. Still trying to get to Shanes level of photo editing so it'll look good on the board. I rinsed until the brown color of the water coming off the roof went away, still "suds" up a little do to residual bleach, didn't worry about getting all of that off. Left over killing power as far as I'm concerned. A fair amount of algae on the roof too.
