    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.

    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.

    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.

    We do a fair amount of warranty work for some shingle manufacturers when the algae resistant roofs get dirty before they are supposed to

    I ended up writing an entire blog about what a client pays for with roof cleaning. It certainly is NOT just "spraying bleach" on a roof. As we all know, there is so much more, and MANY good reasons for them to hire RCIA certified roof cleaning companies.

    What is it that a client gets when they hire a professional roof cleaner? Some people say, "it's just spraying bleach on a roof", and they're wrong before the words even leave their mouth. What the client pays for when they hire us to do a roof cleaning isn't just some bleach sprayed on a roof. Professional roof cleaning contractors are using a much more powerful version of a chemical they barely know. In fact, we're purchasing it in just about the purest form they can manufacture and ship it. The client isn't paying for some monkey to trample their roof and lay waste to their landscaping with a chemical that can oxidize any organic matter to a pile of mush. How about a little lesson in the basics which RCIA certified roof cleaning contractors are well versed in. Professional roof cleaning companies are using 10-12.5% sodium hypochlorite, which is often sold as "pool chlorine" and in much lower concentrations as "bleach". When sold as household bleach, it can and is often be combined with other ingredients. Sodium hypochlorite is a strong oxidizing agent. Through the process of oxidation, the algae (actually cyanobacteria) is killed, and mostly removed. Rinsing helps this final removal process, but is often left to rain to finish. Using advanced proprietary cleaners along with the sodium hypochlorite helps remove the algae residue. This is effective if the roof is rinsed immediately, or later by rain. Spraying liquids and climbing roofs is not as simple as it seems, just because the ingredient is known. I know flour is in a cake, but I couldn't tell you how to bake one. Let's set aside a myth and miscommunication real fast. "Chlorine" is a gas, we don't clean with "chlorine". Sodium hypochlorite is often made by passing chlorine gas through sodium hydroxide, or through electrolysis of a heavy brine solution. In water sodium hypochlorite forms hypochlorous acid and a chlorite ion. Sodium hypochlorite oxidizes algae via the chlorite ions which basically give up their strength during the process, leaving behind nothing but sodium and hydrogen, a.k.a. salt water. Sodium hypochlorite breaks down rapidly in the sunlight, and this actually helps the oxidation and roof cleaning process. It also helps remove the strength from the formula during cleaning, which can help with protecting landscaping. Did you know it is one of the most environmentally friendly cleaning chemicals on earth? It's in everything, including our own food and water! The danger is minimal when handled properly, even for the environment. However, when handled improperly, a lot of damage can be done using such strong chemicals. When a client pays for a roof cleaning, they are paying for experts in their field. People who are educated and know how to wield these chemicals carefully and properly. Nobody will mistaken my deflated pile of smoldering carbon mush to be considered a cake, will they? Roof cleaning customers are paying for people who have perfected a craft, and can safely restore their image without damage. Does your roof cleaner really know what he's doing? Does he really comprehend the cleaners he's using, their properties, safe handling, and how and why the process works? If not, why hire them? It's obvious what a roof cleaning customer is really paying for. The clients are paying for someone who has the skill to lay waste to thousands of square feet of algae, moss, lichen, and other roof infesting organisms, without damaging their plants, finished on their homes, etc. As said experts, we all know that even the best roof cleaners can have difficulty. Low water supply, really hot day, steep roof, no gutters. Recipe for disaster. These clients aren't paying for some $100 "bleach" jockey to destroy their property. A roof cleaning customer is paying for someone who knows the chemicals, their safe handling and applications, the processes, precautions, and more. Clients are paying for roof cleaning companies that comprehend the process of oxidation that allows the removal of these organisms. They're paying for people who know how to care for the landscaping, the finishes on the home, and other things in the vicinity of the roof cleaning. They're paying for responsible roof cleaning contractors, hopefully RCIA certified experts, that know all the steps to make sure a roof cleaning goes off without a hitch, AND is there to stand behind their work in the unlikely event something does wrong. This is a point that can't be stressed enough. Our clients don't pay us just to "spray some bleach". They pay us to handle a delicate task, and take on the liability as well. Not everyone who can "spray bleach" can do that. If even the best of the best can have challenges roof cleaning, why on earth would ANYONE hire a jack of all trades Jim Bob with a pickup to clean their roof? There is simply too much at stake. What the client is really paying for is competent, safety conscious, diligent roof cleaners who are experts in their field. That's what they're really paying for. The expertise.....not "spraying bleach". Any dummy can buy some "bleach"...not everyone can handle proper, safe, approved roof cleaning methods wielding industrial strength sodium hypochlorite like a professional RCIA roof cleaning company can, AND stand behind their clients should any issues occur. Amazing results, and peace of mind are worth a thousands words.

    In Northern California we always rinse our roofs (unless rain is imminent). There is a few reasons for this. 1. In the South East, there is fairly consistent rainfall throughout the year. The rain quickly rinses and finishes up the roof cleaning process. In Northern California we commonly go months without rain in the Summer. Rinsing or roofs after cleaning gives them about a 20% cleaner appearance immediately. The homeowners appreciate not having to wait months for that extra 20%. 2. Nearly all of our roofs have gutters. 60% being galvanized steel. Both Sodium Hypochlorite as well as salt are corrosives. Not rinsing roof jacks, solar and skylight hardware, gutters and downspouts could potentially leave corrosives on these for months. This is something that homeowners are unaware of, but we are. At times we explain this and the homeowners are always appreciative. 3. We take aerial photos of most of our work. A rinsed roof always looks better. We could come back after rain but we almost never do. So for us its worth it to do it all on the same visit.

    We’re thankful here in the Midwest we don’t have to rinse roofs. I’ve cleaned over 1,000 properties myself and rinse very few. Those are the ones with heavy moss and lichen in which I know the wind and rain won’t get to. Other than that, all we do is flush gutters and it’s all gravy :). I killed one plant out of all those roofs. Just the cost of business.

    Working between the rains might be a benefit. You get a free rinse the same day! As long as it’s enough to dilute the mix coming off the roof.

    Well..... How much does shipping really cost on 4-6 BUCKETS of snot, clingon, Hang Tite, Green Wash or anything else? $100 for 4 on the very low side, $135 for 4 on the higher side, $150 for 6 and $210 for 6 buckets! That adds a whole lot to your bottom line. The more you pay for your chem, the less that goes in your pocket. A single bucket of this dense surfactant that takes the place of 4-6 buckets costs anywhere from $20-45 to ship in the US. We don’t pad shipping and put it in a box to save a $6 you handling fee. We are going to send out new buckets with handles on the bottoms shortly. Soooo, when you look at the cost of shipping a single bucket over shipping out 4-6 buckets, I think the savings speaks for itself!

    I've had time to use slo mo quite a bit. It's like pouring molasses when we measure it for our mix. Needs stirred or cycled through the pump for a good mix. It is sticky!

    For cold weather roof cleaning, some have found it useful to add some of this stuff to the roof cleaning mix, but beware! This stuff will burn your mix up, and make it useless in 2 to 3 hours! 2 to 4 ounces of it, to every 50 gallons of mix, and more is not better. It contains an oxidizer called Potassium Permonosulfate

    It is always best to rinse a roof. When you rinse, you take control of the entire roof cleaning process, leaving nothing to chance. Depending on rain to rinse a roof with no gutters is sort of like playing Russian Roulette. IF you get a good long rain, you are usually home free, but if you get a slow, 1/2 ass rain, look out! Plants can easily be compromised. OK, it takes longer to rinse a roof, but we suggest you at the very least rinse 1/3 of the roof, the bottom 1/3 Experience has shown this to prevent wholesale slaughter of the plants.

    It must be remembered WHO ARMA really is. They are merely a trade association who have "put themselves in charge" of representing the business interests of roofing shingle manufactures. Sort of like the BBB "represents" Businesses. They are NOT the shingle makers themselves. Any professional roof cleaner knows the ARMA Roof Cleaning Solution will not clean a roof. Some people think ARMA knows their cleaning solution does not work, and planned it that way, so people will buy a brand new roof, and THINK that their shingle roof can't be cleaned

    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

    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.

    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.

    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.

    Moss On old shingles

    From what I have read you have to hit it with a strong roof mix and let it dewell ... and when the moss dies the rain should wash all the moss out ,, don’t quote me on it I am a newbie too.. and when I mean dewell I mean for a couple days , make sure no rain in the forecast ..

    Awesome! The biggest mistake many make when it is cold outside, is not waiting long enough for the mix to clean. I discovered this 27 years ago, it was a 38 degree morning here in Tampa, and I had a large grey shingle roof that "refused" to clean. I ran myself out of chemical, drove to get more, and when I returned an hour and a half later, the roof was clean! LOL, I thought someone was playing a joke, and cleaned the roof for me, until I figured out what was going wrong. Back then, there was no roof cleaning forum, and no one to ask questions of. I had to figure out this stuff for myself.
