Many are under the mistaken impression that simply cleaning a roof with TSP/Chlorine/Water is "treating" the roof, and somehow "preventing" the algae from growing back.

Lets take a quick peek at what really happens ?

The Sodium Hypochlorite releases Chlorine, it cleans the roof, and most of it is evaporated in 24 hours, sooner if it is hot outside.

What is left behind is sodium chloride, commonly called Table Salt.

Believe it or not, common Salt is a Biostat.
A Biostat prevents plant growth, as opposed to a biocide that kills a plant.

But, soon the salt is scattered by the wind, or washed off by the rain, or the cleaning contractor.

BORAX on the other hand is much longer lasting.

Ever heard of Boric Acid ?

Before we started using what we do now, a chemist we hired to do consulting for us suggested it's use.

You do not need much, 1/2 8 ounce cup per total gallon of mix.

It seemed to make it clean better too.

I have also field tested with, and w/o Borax, and found about a 3 to 6 month improvement in roofs staying clean with it.

It's cheap like TSP, it works, and will give you an "edge" on your competition.

The picture below is me spraying a roof.
This is an OLD picture, and we were using Borax then, and of course, TSP.

See how wide that pattern is ?
This is because the Gun we use places a nozzle farther away from the roof, giving it more time to develop it's pattern.

Here is the truck powering that gun/hose combo.

Yep, it's a BOX TRUCK .....
Notice those Titan Stainless Reels, and the AG hose?

BTW, that is "ONLY" a 25 degree nozzle I am using.

25 degrees is plenty, IF it has enough time to fan out.

so why do you use tsp instead of borax
I have always used TSP AJ.
I heard about Borax from a Chemist who suggested it's addition to my mix.
One can clean a roof with simply water and chlorine w/o any TSP or Borax.
And, for those that do not use TSP, just Water and Chlorine, they can add a little Borax to the mix if they like.

Borax just provides a little longer lasting protection for the roof from Algae re growth, that is all.

It also seemed to clean a bit better too, but that is subjective.

The mind can play tricks on you sometime, LOL

I just found this about Borax in a search

Borax is a naturally occurring mineral (Hydrated sodium borate, Na2B4O7 -10H2O), soluble in water. Borax can deodorize, inhibit the growth of mildew and mold, boost the cleaning power of soap or detergent, remove stains, and can be used with attractants such as sugar to kill cockroaches.

TSP and other chems

TSP is not a new secret, although it may be considered one in some areas. The benefit to TSP is that it can be applied in a light mist, instead of a high volume low pressure (HVLP) tip application system which normally causes drippage over the edge of the roof. TSP can be used without a normal heavy rinse. Just mist, wait, mist, wait, mist, wait, most 3000ft tile roofs can be cleaned with ZERO pressure using TSP and about 4 hours. A direct application system is neccessary as TSP will not work pulled @ 5 to 1. I still recommend that few cups of laundry detergent, and for the beginners...a couple gallons of chlorine is ok (that will help you clean as the detergent bonds the chem to the surface).
If you know what you're doing, chlorine can be used in ANY application safely. I do however, recommend a NON chlorine cleaner for asphalt/fiberglass shingle roofs, as my research does show considerable ware from chlorine. (of course, Roof-Brite Inc uses "Roof-Brite", exclusive to us). Keep in mind, that it's NOT (despite what most people think) good to ELIMINATE the use of chlorine... it's better to eliminate IDIOTS who misuse it. Without chlorine, or a STRONG biocide, you will NOT kill mold (go ahead and argue it .. of course I don't argue with anyone, but go ahead, you'll find out it's true) spores and ALL existing biological growth. Detergents, cleaners, soaps, etc are great for shingle roofs (guys who use those non chlorine cleaners on tile roofs are struggling unless using TSP or close), but a fungicide must be used to kill the living bacteria...otherwise the roof looks clean, but it's still CRAWLING WITH FUNGUS

Is Roof Brite associated with Heefernan ?
It is SO confusing ?

heeferwho??

"American Roof-Brite" is a company I've heard of and seen alot of, but I'm not sure if that's who you're talking about. Gary Boyd(the dealership owner/inventor of "roof brite" cleaning agent) won a law suit against another "roof brite" name company, I don't know if they later became "american roof brite" or not. I work for the Palm Coast location. I used to own "MightyMike's Low Pressure Exterior Cleaning".
Also, thank you apple, I checked out some of those elec pumps you posted. I still stick with gas power apps, or run my chems str8 through my injector, but it's nice to know there's other options available.

Heefernan was the original American Roof Brite owner.
It is SO confusing ...

I like Gas pumps better too, I just post about electric pumps for those not into roof cleaning as much as some are.

So years later are these the best choices?
Always working on new and better chemicals to push the roof cleaning envelope Ron. Been exposing Tampa Roof Cleaning Scams too lately.
Guys are hitting Tampa Palms with time release roof cleaning offers, then they leave town. Of course, the roofs never clean!
