Roof cleaning

[badger11]

Hey all, a question for those of you that use a TSP and bleach mix for roof cleaning.
How many gallons of solution do you use for lets say a 1000 square foot roof?
I saw a company stating that they use 200 to 300 gallons of solution for roof cleaning.
That seems high to me. I am trying to figure out how big of a tank I need for mix.

I guess you all are to busy making money to respond to the post.

O-well, have a good one.

Badger,

Sometimes it takes a while to get a response, don't give up keep asking questions.

I think most people respond better to someone with a name and a location.

I would use 8 to 10 gallons on 1000 sq ft of roof, or approx. 100 to 125 sq ft per gallon. This will vary with how bad the roof is and also the outside temperature. Let it get above 60 deg F. Sun is good and low wind is better. Good Luck.

Have a good day... whoever you are and ... wherever you are.

Hey thanks for the response. My name is Andrew Lemick and I live in Columbus, Ohio. As you can tell I am just getting started in the biz.

I wonder why that company say they use 200 to 300 gallons of mix on a single roof. Does not make sense to me.

Again thanks for your reponses.

I looked at that site you posted. There statment of 200-300 gal of there "special solution" is 3%-6% sodium hypochlrite. (diluted liquid pool chlorine. Roofing manufacture assoc reccomends using 3%-6% solution let it dwell for about 15 minutes and rinse. Some people will not rinse but I feal its needed.

When I do roofs I use a 60-40 ratio. 60% water and 40% chlorine. This will give you the 3%-6% mix. I let it sit and rinse. a typlical 2000 sq ft house I will use between 20-30 gals of chlorine. I always wet down the surrounding lanscape before and after I am done doing the roof. With my 60/40 mix is about 80 gals. and then the rinsing could be aroung 100 gallons of water. Hence the 200-300 gals of the "special solution".

Using a battery operated pump like a shurflo is fine for applying the chems to the roof. Its just not as fast as using a gas powered pump.

The shurflo I use is a 3gal per minute pump and works ok.

I am switching to a hypro roller pump for this season. Its a low pressure pump that will flow about 20 gal per minute and runs off a 5 hp motor. As you can see this new pump for me should make my time doing roofs alot quicker than before.

We are setting up a roller pump driven by a 5.5 HP Honda for chemical pre-spraying for one of our customers next week.

1000 SQ , I WOULD SAY ABOUT 20 TO 25 GALLONS OF MIX.

Hello my name is nick.By reading about these roof cleaning questions I came up wth one of my own.IM in search of a mold and mildew cleaner that will remove all alegea from asphalt shingles without using pressure.Lots of people dont want pressure or chlorine on there roofs.I also notice guys are advertising chemical wash no pressure.Now I know I can use my soap injector nozzle for the high volume rinse, but its the chemical im having a problem locating.I did get something from a place calledshingle care, but it didnt do the job they claimed it would. Mabe you can advise me of a chemical and were to purchase it. I thankyou for any help you ca give me.
