  4. Rinsing A Roof After Cleaning

    Ive taken to not cleaning roofs if there are no gutters. Not worth the risk. If I do take a job with no gutters I fully warn the customer of the potential "kill zone". 97% of homes in my area have gutters so losing a potential nightmare isn't to bad.

    How old is that roof? It'll come clean, but I think its to late for the "like new" appearance once its clean.
  6. ARMA Roof Cleaning

    Yea I hear that sometimes. More often the customer questions the strength required versus what the bulletin states and the leave it on the roof, again versus the bulletin

  8. ARMA Roof Cleaning

    Actually, I was probably the person who first started using the ARMA Roof Cleaning Bulletin, over 20 years ago. Back then, non pressure roof cleaning was scoffed at, and almost totally unknown. I was battling pressure washers back then, who used high pressure to clean a roof. It was easy to say "Mr Customer, the shingle manufacturers say that the ARMA Method of Roof Cleaning is the correct one, as you can see by this ARMA Bulletin" Until one day, a savvy customers said "WTF do you mean 1500.00 to clean my roof, when all you are doing is spraying some diluted Bleach and TSP on my roof". LOL, that was the end of us using the ARMA Bulletin to sell roof cleaning customers for us

    Thank you for your commitment in knowing the answers. You truly are the godfather for Roof Cleaning! Great Info....
  10. ARMA Roof Cleaning

    Yea they really need to update their directions on cleaning a roof. Maybe listen to the people that have been cleaning them for years. It is very hard to explain to a very diligent customer the right way to clean a roof after they've read the technical bulletin from the manufacturer.
  11. Moss On old shingles

    There is no real Moss to speak of here in Tampa , but the Killing power of SH is best at lower PH's (diluted). The stronger your SH Solution is (like 50/50), the higher your PH is. However, the penetration power of the SH is best at higher PH levels. It is the penetration of the SH (oxidation) that makes the Moss turn white. When we do roof treatments, we use a 15 - 20 % solution. Weaker solutions (no too weak) kill better. However, in your case, you may need the increased penetration of a stronger solution ? A weaker solution may lack the oxidation potential to penetrate the Moss enough to kill it. My opinion is this, as long as you soak the chit out of the moss with a weaker solution, you will be good to go. The TRICK is to be sure the Moss is soaked (saturated) to ensure you kill it ! Mechanisms of actions of sodium hypochlorite in cleaning and disinfection processes. Fukuzaki S1. Author information Abstract Sodium hypochlorite (NaOCl) is the most widely used disinfectant in the food industry despite the increasing availability of other disinfectants. Sodium hypochlorite fulfills many requirements as the ideal disinfectant and furthermore it has an excellent cleaning action. The effectiveness of sodium hypochlorite in the cleaning and disinfection processes depends on the concentration of available chlorine and the pH of the solution. Hypochlorous acid (HOCl) is a weak acid and dissociates to the hypochlorite ion (-OCl) and proton (H+) depending on the solution pH. It is generally believed that HOCl is the active species in the germicidal action, whereas the concentration of -OCl is a key factor determining the cleaning efficiency. This implies that the optimal pH region of the germicidal activity of sodium hypochlorite differs from that of its cleaning activity. This paper describes the theory and practice of the cleaning and disinfecting operations based on the use of sodium hypochlorite solution.
  12. Rinsing A Roof After Cleaning

    There has always been a big debate whether a cleaned roof should be rinsed, or not. Remember, we are not cleaning a roof with Acid! Acid basically keeps working, unless it is rinsed well and/or neutralized. Not so with SH. The SH hits the organic matter, and the hypochlorite ION forms. This ION goes through a battle with the organic matter (algae) on the shingles, and this battle pretty much weakens the SH so much, no Hypochlorite ION is left. Sort of like the way Peroxide burns on a cut for awhile, then fizzes out. However, what is left behind after the reaction between SH and organic matter is a form of salt. Salt will mess up plants. This is why we rinse a roof, at least partially, if no gutters are present. My roof cleaners are taught at the RCIA to rinse the bottom 1/3 of the roof, from the ground, and then rinse this run off off the plants. Experience has shown this will prevent 90% of any run off problems.
  13. ARMA Roof Cleaning

    ARMA methods of roof cleaning are one big Joke. Any roof cleaner knows the so called ARMA Method will never clean a roof. It calls for diluted bleach, so if 5% straight bleach will not clean a roof, how will diluted bleach ? And, make no mistake, ARMA is talking about store bought bleach, NOT 12.5 % SH. ARMA is nothing but a trade association who claim they represent roofing shingle manufacturers. I have had several conversations over the years with Owens Corning Technical Services division in Ohio, who assured me it was ok to not rinse a roof from a shingle life point of view. However, from a liability POV, it is a different story if the left on bleach and soap run off the roof, and get in the eye of a child or pet Left on bleach is basically salt, salt will not harm asphalt, or every McDonalds parking lot would be destroyed by spilled french fries.

    The SH has 2 components it breaks down into, depending on the PH. One is the Hyperchlorite ION, the other is Hyperchlorus Acid. It is the ACID that does the killing/disinfecting, and this forms best at lower PH levels. One reason we dump ACID into our swimming pools, to lower the PH, and increase the killing power. The cleaning part of SH is called the Hyperchlorite ION, it is most active above PH 10 - 12. It does the cleaning, and since it is an oxidizer, it increases penetration into the Moss. From just a KILLING Point Of View, diluted SH kills better then a 50/50 mixture, and acidified SH kills even better! Now, I know WTF I am doing, but I dont want you or anyone else to attempt to acidify the SH, OR YOU CAN DIE ! For now, drop to a 15 to 20% SH to water solution vs a 50/50 solution, and STF out of the Moss. I mean, really soak it good.

    Those glazed tile roofs are a real bitch, when it gets cold

    This looks a lot like roof in Seattle and Oregon, tons of Moss
  22. Moss On old shingles

    This is typical in my area. Anyone have any suggestions to help a newbie?
  23. Cold Weather Roof Cleaning

    Trying to finish one tomorrow that I couldn't get on Friday. Took forever just to do a couple sides because there was zero sun and cool and windy. That one seriously frustrated me! Also it's glazed tile, so not being porous it won't absorb the SH. I'm having to kill layer by layer and it's super dirty.
  24. Warranty Roof Cleaning Jacksonville, Florida

    Sometimes roof cleaning is prescribed by the manufacturer themselves, as a way to protect the integrity of the roofing system. Warranty roof cleaning in Jacksonville, Florida is something Ultrasoft has great experience with. Since all environments are different, and not all are ideal, sometimes growth and buildup can be heavy and rapid. Due to surrounding conditions, even newer roofs under manufacturer's warranty can be subject to heavy organic growth. Often this growth is simply gleocapsa magma, and is easily remedied. Other times it can include growth like moss, lichens, and other contaminants. Shingle manufacturers will sometimes prescribe roof cleaning where algae resistant shingles are unable to cope with the rapid organic growth. These warranty cleanings are something Ultrasoft Pressure Washing specializes in. Since we are RCIA certified roof cleaning company, and use only the best zero pressure cleaning methods, we are an easy choice for the manufacturers and their warranty roof cleaning in Jacksonville, Florida. The standards for roof cleaning for RCIA certified contractors meet and exceed standards set forth by ARMA (Asphalt Roofing Manufacturers Assocation). If roofing manufacturers count on the qualified, certified, educated, and experienced professionals at Ultrasoft Pressure Washing, you can definitely count on us for your roof cleaning needs. Here is an example of our roof cleaning, using safe, environmentally friendly zero pressure methods. This is a roof cleaned and restored for a popular shingle manufacturer. You can see heavy growth, most likely due to heavy debris sitting on this roof. Not only do we clean roofs for shingle manufacturers, but for roof conctractors, families, businesses, and just about anyone else in the Jacksonville, Florida area.

    I don't envy roofs that look like that! However, you wouldn't envy standing on a roof down here in Florida in the middle of August! Welcome.

    Just joined today I'm on the west coast of Canada. Lots of great information! Thank you. Here is a typical West coast roof
  27. Hello All, I am in Central Arkansas, and a friend and I would like to start a “Curb Appeal” business. I am getting into real estate, and early on I have stumbled upon conversations about soft washing capabilities and it would seem most of the population here is unaware of the product/results. But, I am worried about the risks! I have heard that a “proper” soft wash solution (3:7 or 2:3 of 12.5%) will scorch a lawn and flowerbed. I can respect that with fast results should come proper care and preparation. I’ve also heard that the only tried and true method to prevent that is to have a 2nd guy spraying. Well, we would only have one. I know I mentioned the pair of us were starting this venture, but I have a job I need to maintain to keep the marketing going (which I am confident about). And, we have no desire to hire a 3rd employee. So, The question is this: If one guy goes out to soft wash a single story home with moderate plant life around, AND NO WATER GUY, are we asking for trouble? I would hate to make money on 9 homes and then lose it all on the 10th. Or, am I overthinking it? We also want to do concrete, there are a lot of large driveways around here, but there are small areas as well. 8gpm and 36” too much of an investment? Our wish list is the following: 6x12 enclosed trailer, 8gpm 3500 psi Pro, X-Jet, Bandit Roof System, 36” Whisper, 225 gal container, 50 gal container. My measurements say that will fit, but maybe some of you know from experience that it will not. Is training for this kind of thing a waste of money? Thank you for any input, Mike Z - Little Rock

    A wet roof is not a problem UNLESS it is raining so hard that you can't keep the chemicals on the roof
