Cold Weather roof cleaning

Doug I'm confused. If you don't rinse then what's the extended 5-10 minutes. Maybe I'm not reading something right. We have always rinsed our sh and surfactant off the roof
 
It's a commercial job I can't tell them that the lichen will wash away after a couple rains. Is that how you clean your roofs without rinsing. Or will your mix work without anything happening. I'm still confused about dwell time if your not rinsing. Sorry to be a pain in the ass.

We would all like to simply dip our meat in Terayki Sauce, but for maximum flavor, we soak our meat (marinate) it overnight.
Same with algae and especially Lichens. Do NOT rinse the roof, allow the algae and Lichens to "marinate" in the Love!
Just like you might take Antibiotics for a few weeks to fully Kill an Infection, you need to allow the Sauce to dwell on the roof as long as possible. Bleach does not always kill completely on contact, so simply leave it on the roof, and let God rinse it.
If you are hardheaded, and will not listen to us, and feel you must rinse, here is what to do.
Clean the roof, then go eat lunch, play pool, whatever, and come back an hour later. Then rinse, after an hours dwell time.
But, whatever you do, do not ever rinse a roof w/o allowing at least an hours dwell time.
 
Thanks for the info Chris. Its not my choice on rinsing or not. I honestly have no problem letting the typical roof sit and let mother nature do its thing but on this particular job it has alot heavier lichen build then most and we didnt put anything in the contract about waiting over some time and it will disappear. We actually never do because the roofs typically show results by the time we pack up. I was trying to see how everyone else approaches roofs like this. It is also a couple hours away from our shop so I may take a lunch and let it dwell and come back and rinse down. They were getting ready to replace this somewhat newer roof until I stepped in and offfered the alternative. I believe if it looks even half as good as it did then they will be happy with the money they just saved.

That's Cool Rod! Lichen are a PITA. We "get out" of removing Lichen by telling customers it is best to allow them to die, and fall off naturally. But every now and then you get a really demanding customer who will insist that every "imperfection" on a roof be made perfect, right away.
A little trick I am sure you know is this, when I am done cleaning a roof I always exclaim "Wow, look at the difference" !
Even if it is not my best job!
Customers are like Dogs, who read your Body Language. We find that 90 percent of the time, if we act happy with the job, the customer is happy.
And, as you already know Rod, any roof that has been chemically cleaned, will continue to look better, after some rain.

LOL, I once had a ground man, who would point out spots I missed to me AND Customers! Needless to say, he was soon unemployed!
 
Lately we have been running a bead of rinse water on most all of our tile and shingle roofs but mainly only directly under where there could be a potential for some damage to sensitive plants and or shrubs. Its winter here and we are not getting as much rain as we do in the summer but we still get a lot of morning dew. Just don't want anything dripping slowly that could damage anything . Most of the roofs we clean don't have gutters. This can become a problem if precautions are not taken.
 
Good point Larry. We had some light rain that was about to come through last Thursday right after cleaning a roof. For the first time in a while, I lightly rinsed a portion of the tile roof that would drip onto a row of hedges.
