Any pointers for cleaning a roof while it’s raining slightly? It’s not raining enough to stop working, but I’m concerned it may dilute my solution?
What do you guys do in this situation?
I noticed the roof being already wet the SH Doesn’t foam as much as it would normally when it hits the algae.
A light drizzle you’ll be fine with a 50/50 mix.
I have 3/4” mixing valves. SH set on 40 degrees and water set on 90 degrees. I don’t know what 50/50 would be. It’s not foaming but it still looks like it’s coming clean. Just harder for me to walk on the roof hah.
To get 50/50 mix on any proportioning system Both your valves sh and water need to be fully open. With 12.5 you should be getting 6.25 out the tip.
What percent sh are you using
12.5 %
I finished the job, despite the rain. I used a little more SH than I wanted, but put $1500 in my pocket so all is well. Thanks for the tips.
There is nothing like Mother Nature watering down the property. Good Job!
