There’s a bit confusion when we do our soft washing on roofs, and I wanted to clear it up.
When we soft wash a roof and we’re spraying our chemical mixture on the roof, we get asked why don’t you rinse it off? And here is our reasoning, we will rinse the house after but most of the time we will leave the roof alone.
1. Less run off. Runoff is extra checmial that didn’t cling to a shingle, and just runs off the roof, we want to minimize that to the best of our ability because we don’t want to rinse off fresh chemical that could still be cleaning and put the plants down low in danger.
2. A saying we use is “If it’s brown it’s going down, if it’s black you’re getting a call back.”
When the organics die on the roof they tend to turn brown and sit on the shingles. Can it be rinsed off? Yes but we prefer the rain to do that and we will explain why below.
If it’s black you’re getting a call back, the organics on your roof are still alive if it’s still black after we spray it which means we need to do another coat to kill them!
3. Why don’t you rinse? The big question.
We do sometimes! Every roof is different but, When we spray our mixture on the roof it begins it’s work, our main ingredient is Chorine, because of the SH (sodium hypo chloride) in it. and with chlorine, the longer it’s exposed the less effective it is. And with how expensive everything is I’d want to get the full cleaning effect out of it, wouldn’t you?
Now, with that being said there’s multiple elements that will activate the SH, but Rain and Heat are the main 2 we experience. We want the SH to stay on the roof because we want it to continue cleaning even after we have left. And after a while the rain will just rinse everything off the roof naturally, leaving you with a clean roof!
4. Why wait for rain and not use a hose?
Rain will dilute everything at one time and rinse the roof off in minutes, where if we use a hose it could take us hours, and if we do it too early, the chemicals are still active and we’re rinsing good chemical that could still be cleaning off the roof.
I hope you have a amazing day guys! Just wanted to put that out there for anyone who isn’t familiar!
