We did this one today. It was the most challenging roof I have ever done by far. It was older and had any and all of the plant life you can imagine on both sides. I wanted to get a picture of the lichen but I forgot to snap it...They were all huge. It had rust stains as well....

Two applications and some waiting around and it dried a slight brownish color because the algae was so thick. We rinsed and rinsed to try to make it look somewhat acceptable. I will post afters in the next day or so.

I think this one might take a few good hot days and them some pounding rains to clean up well.

By the way, that is SH and Bob's (Pressure Tek) Simple Cherry in the mix. It has a great cling and dries clear. Rinses really nice.

Wow....that thing was nasty!

What the recipe? I never have it foam up and be so white when we do them.

Dave222 · 03-17-2010, 07:23 AM

I put two cups of Simple Cherry per 50 gallons of mixed Water and SH.

I also have a few proprietary items I add that I can't talk about because I have to keep some stuff close to the vest.

Kidding of course. I hate when people do that myself. It is just SH and simple cherry as described above.

Good job!!

I bid on a community of 44 bldgs and most of them look like that. The HOA meets tonight to make the decision, fingers crossed

That is our solution as well. It works great, but I never get the roof to foam up or lather up so white. I wonder if it's the size hose you are using. We use a 5/8 hose and the 5800 series delvan pump. (I think its the 5800 pump)

Anywho....it looks good.Looking forward to see the "after" pics especially with the Lichens

I just updated my trailer. Two Fat Boy pumps with heavy duty batteries all enclosed in a weather proof set up. It works well. It is nice to park at night and just plug it in to the charger (also completely weather proof) and not have to worry about rain or unloading crap everywehere. 1/2 inch hose by the way. 200 feet of the mean green.

I will post some pics maybe at some point.
