    I think if you find a supplier of liquid chlorine in bulk, you may well find that you can use less chems to get the same result.

    I hope this is the case. Maybe Bates Chemical Co. will be my answer.

    However, I might have mentioned this before but I've had to buy 6% when I was desperate (multiple occasions) and it took several coats plus misting on the different jobs. I believe I read here that 6% is the lowest SH will decompose.

    Must be some special strain of mold that somehow got loose in your area.

    I was talking with a roof cleaner in Florida that informed me that most houses you all clean are some what shaded by trees. He also said that on houses that have no shade the mold only grows on the north side because the sun bakes and kills the mold.

    I'm not quoting him but this what the gist of it.

    Anyways, if this is true then I thought you'd like to know this...

    90% of the houses I clean have no trees and no shade. The mold that bakes in the sun all day is just as thick as the mold on the North side.

    Regardless of whether it's "incredi-mold" or not I know that if you use 50/50 you'd find yourself applying 2 or more coats then misting spots.

    Mel,

    Wanna know something wierd? I've yet to see a tile roof down here that needs cleaning! There's many OLD OLD houses down here with the original tile roofs on them that don't get mold on them. I don't know why but I just thought I'd let you know. Btw, that 's some pretty serious mold on that roof of yours!

    Shane,

    It would be great of you to give me their contact info! I don't care if it's even more than what I'm paying... I absolutely HATE openeing each box, opening each bottle then hand dumping it into my tank then disposing of all that plastic and cardboard.

    Scott,

    I do buy it from a pool store warehouse and it's called "Shock".

    It's the ONLY place (that I've found) I can get it locally.

    To all,

    I've mentioned this before but...

    We have an average rainfall similar to Hawaii

    There are over 20 full scale "Plants" in our area (not the living green things)

    We have an average humidity of 85%

    and a few other reasons I can't think of.

    This is why I believe the mold in MY area (not Tx in general) is a lot worse than most places.

    Scott,

    Thanks for your concern about the strenghth of my suppliers chems but I don't think that's the case. The reason my chems cost so much is because each gallon is in it's own jug and each set of four jugs get thier own sealed cardboard box. The warehouse is completely air conditioned and even if the boxes where stored in direct sunlight (and they arn't) the carboard keeps it shockingly cool inside the box (I've placed a box in 95 degree heat all day just to see).

    There are times when I couldn't get 10.5% and I had to use straight 6%. With regular bleach (bought at super walmart) it takes 2 coats and then I still have to spray a few spots.

    How are you applying it? The only time I have to apply more than one coat (other than a few areas, typically) is if I was using it a bit weaker, around a 30/70 mix of 10.5% and water. 80% just seems a bit strong for shingles, especially if you're having to re-apply. Using a 50/50 mix and a relatively small tip in the shurflo, I can do an entire roof with almost no runoff at all, and not have to reapply. Sometimes there are a few spots that just won't come clean with one application, but that's at most 5% of the roof surface, usually much less than that.

    When I re-apply it's usually a few spots that I know will have trouble rinsing. However, I recently did a house that took 3 entire coats at 80%! My application process is no different than yours or anyone elses (except people that x-jet). The difference is the mold.

    Mel,

    What kind of hose and and wand set-up do you use with that pump? Also, where'd you get it? I'm also assuming that with a stream like that you don't need to actually get on the roof to rinse?

    Also, do you hook up to the water hose or use a tank?

    Sorry for all the questions it's just that rinsing is my biggest time consumer. I did a test with several water hoses in different areas of south east texas and got an average of 3gpm.

    If what Grant posted is accurate then I don't see what the problem is by measuring.

    It takes no more than 10 min to find the sf of the roof of most large houses and also makes you look more professional. Even if I wanted to "eyeball" (and I could) what to say when the customer asks how you price it?

    Call it newbie'ness but I'm just willing to take the time to be accurate and my method will always look and be more proffessional than the "eyeball" method.
