Wow! very nice. I have 1 coming up tomorrow and I was concerned about oxidation using a regular mix. Thinkin maybe I should go down to about 15 0r 20 % SH and use a brush.Any thoughts on this?
I used a light sh mix and a soft brush on that roof. I did have to get on the roof to clean out the valleys. I used a hook ladder, it hooks over the peek of the roof. I then walked up it and cleaned the valleys, the rest was done from a ladder, and a brush that extends 20 ft. I sprayed roof let sit about 5 to ten min max, had my helper start the brushing, then went back and started washing it off with a garden hose, used lots of water wanted roof to be sh free when I was done. lots of run off also, so did a ton of watering on the ground before I started.
