Hey everyone, I  did some test cleaning with the love and I noticed that I had to rinse to thouroughly remove the remaning algae from the roof.

In the first pic the left side was not rinsed and the right was. The algae that wasnt removed by rinsing ended up drying back on to the shingles, but when rinsed no leftover algae was present. Any comments? Thanks

 LOL, I could give you a long, lenghty explanation, or the short version.

Your chit was too weak is the short version 

You either bought some OLD SH, or your mix ratio was not enough. Buy fresher stuff next time, or simple use what you have by going up 20 percent. So, if you went 30/70 on this stuff, go up to 50/50, and you will be fine.

 This is NOT good practice, but let me say this. Back a long long time ago, we cleaned a roof 250 miles away (It paid 3500.00)

Turns out, several spots did not take. The guy sent us pictures, it looked similar to this, in a few spots.

The customer told us not to hurry, so we waited for another roof to do down there. It never came, and I felt bad. I called the customer, he looked at the spots on the back of his house, and they were GONE !

The  RAIN cleaned his roof, our stuff killed the algae, the rain after many months rinsed it away.

Make no mistake, if you allowed the solution to sit on the roof for 20 minutes or more, the algae is DEAD. It will simply rine away, with time. BUT, this is not how we do business. You told the customer his roof will be clean right away.

The Sh probably was weak because I got it about two weeks from the time I cleand that roof. I ended up rinsing off the dead algae and it came out great, but It definetly cleaned better when it was fresh.

 Both Bread and Sodium Hypochlorite are best used, when fresh.

We are currently working on a Sodium Hypochlorite activator that you can carry in your truck, exactly for embarassing situations like the one you just had.

Always remember, all we have to offer is our solution, we do not pressure wash roofs. The solution MUST clean, or we have little to offer our customers. Imagine if you had my magic powder on your truck ? The minute you saw your solution was not cleaning, you simply dump some powder in your tank, wait 10 minutes, and it cleans like fresh SH ?

THAT is what I am working on !

 

Until then, buy and use fresh SH, or up the concentration.

Chris I can't wait until you perfect that. That would be GREAT!!!

 Yes, it is looking very promising, so far !

Me too. Lichen has been my problem this year. ALgae is gone after the rain but not the Lichen. Chris T, you had mentioned that you only use ball valves and not wands. would you be willing to share a picture of one? I would like to have a back up or two on hand. Currently I have purchased two wands from Pressure Tek and one is busted already. Thanks for your consideration. I don't know which side of the fence I am writing on, so if you wish to PM me that would be fine. How do you know where we are posting our replies?

 Hey Don,..you will RARELY see lichen gone after only one rain. Lichen can take a month to come off. The hot Sun is probably just as good as rainfall for getting rid of lichen and moss. The Sun degrades the physical properties of lichen and moss,..which results in flaking away. Making an activator for the hypo isn't going to make these problems go away any faster. I mean,.dead is dead,..and killing it with a different mix isn't going to make it any more dead. You have to sell these jobs for what they are,.and NOT over promise,...it is the customers' fault that their roof has the physical growth in the first place. If they don't get it,..just walk away,..because they will be a pain soon after the job.

I also use ball valves without a wand. No need for a wand other than special situations,..like Saturday I did a giant roof, it was a little breezy and it had odd angles  and nowhere to really get a good shot in one place,..so adding a 6' extention allowed for an easy shot to an otherwise dilemma...(used the wand extension for only about a minute),..99% of the time an extension isn't needed and is also more prone to breaking your valve because of the leverage it adds.

The first two we built had had extensions built in and the both broke, now we are using just ball valves.

So, what's the verdict? Rinse or no rinse? It appears that rinsing gives your client a quicker result.

The verdict in my opinion, is that if you are using a strong enough mix, you won't need to rinse to have instant great results!

You have to rinse, if there are no gutters and plants are below the roof edge.

Now, up north they have moss and lichen, I can't speak for that?

Like Jeff said, lichen can rake a up to a month to come off. The only way to get lichen off immediately is by scrubbing aggressively or a pressure washer which neither is a good practice. IMO it's best to let mother nature take care of the rinsing. Once moss is dead it will dry up and flake off with the wind and rain.
