I am just starting my roof cleaning company and I think this may be my first post (maybe 2nd).
I have done a lot of research over the last year or so on this site and have found a wealth of great information and facts related to the roof cleaning business. I want to make sure that I have all of my facts straight but there are a few topics that still seem to remain somewhat controversial.
At the risk of starting a heated debate, I would like to open this thread to those in the business who can answer these questions DEFINITIVELY! I suggest that if you have an answer, that you back it up with some authoritative documentation. Without this, I can see this turning into an "opinionfest". So thank you everyone in advance for helping me out with this.
1. Is Gloeocapsa Magma an algae, mold or a cyanobacteria? Most of the information I have found including this article (http://en.wikipedia.org/wiki/Gloeocapsa_magma) from Wikipedia suggest that it is indeed from the Kingdom: Bacteria. This is contrary to much of the information found on many roof cleaners websites. Some say it is a bacteria, some say it is an algae, some say it is mold and some say that it is any and all. From my limited knowledge of zoology, bacteria, mold and algae are all in different Kindoms and are not related. This would mean that anyone who has said that Gloeocapsa Magma is an algae or mold is wrong! So what are the real facts here?
2. How long does SH mix that is sprayed on a roof stay active? Some guys say that as soon as it dries that is becomes salt and therefor inert. This should mean that if it rains even a little bit that any runoff should not damage plant growth. However, other people say that it is possible for runoff after the first rain to damage the plants and so it is a good idea to rinse all or some of the roof. This should not be the case if only salt remains. So which is it? Is dried SH mix inert or still active? Or can it be reactivated by rain?
3. I have a feeling that this one will still remain a mystery but.....has anyone found any concrete data that suggests one way or the other that Gloeocapsa_magma growth on a roof increases the internal temperature inside the home and will increase cooling costs. What about on a house that already has black shingles?
I eagerly wait responses regarding these questions!
I know Ed.....I tend to think about things too much but not only do I hate to be wrong, I hate pretending to be right about something that I don't really know about.......ya know?
I hear ya brother. When people ask for back up to my shpeel, I just give them Gary's personal cell phone number. Honestly bro, most people really dont care if its a mold, fungus, or rodent. They just want to know that the roof will be clean and it wont cause more harm then good. Most want to be assured that they wont be replacing shingles that were blown apart by a pressure washer. As far as the roof soap, you'll learn how to keep things protected against run off. Some guys tweak the sysem and develop there own style, but overall its the same. Its best to get a few under your belt from friends and family.
Grab a bag of salt. Go out in your yard and pick out your wifes favorite bush. Then pour it all around the base. Most inportant, don't call me in a week looking for a place to live!

At one time cyanobacteria were called blue-green algae and were included with the algae. However, like bacteria and unlike algae, cyanobacteria are prokaryotes, meaning that they do not have a nucleus. For this reason they were removed from the algae (which are eukaryotes) and put into the bacteria, with all the other prokaryotes.

Holy Chit,,,I'm getting a headache reading this post. I thought roof cleaning was easy, but I may have to go back to school to learn how to pronounce those big words.
I know that The stains are a cyanobacteria, but most people still identify with the term algae, so I generally use it with single quotation marks ( 'algae' ) in case someone calls me on it. Also, It is not mold, but because GM maintains moisture longer, it harbors the growth of mold and of course moss and lichen. So it very well may be mold much of the time, and thats good for our business. Please some one correct me if my conclusions are wrong. This is a good stream.
Scott, if you want to be taken seriously here and avoid a serious debate, I suggest you do some more research on the proper roof cleaning techniques instead of worrying about Gloeocapsa Magma terminology.

I'm sure you have read this technical bulletin from ARMA because you said you have done ... ""a lot"" of research but I'll post a link in case you missed it. Pay close attention to the terminology and even more attention to the "Caution" towards the bottom of the page.
Scott it is a good idea to be correct when answering a customers questions but to be honest with you if a customers wants to sit and debate about my Biology knowledge or if it is a cyanobacteria , that is not a customer that I will clean a roof for. Scott you should listen to Ed Thompson he is a memeber with alot of experience. As far as the internal temp question, Go stand out in the direct sun light on a 90 degree day with a white shirt on and stay there for 10 mins, then do it with a black shirt on. Black shingles are the hottest shingle a customer can put on ther home I always try to recommend a blended color to a customer when intalling a new roof and it is because that a dark black shingle does attract the sun. Good luck Scott
I realize that there is just a small chance that the topic will come up with a customer, the main reason I want to be correct is that I am still building my website and if I am going to "educate" my customers, I don't want to give them wrong information. I think it is important, as an industry, to be consistant with our information. Conflicting information makes us look unprofessional, IMHO.
I have won multiple jobs due to having far more knowledge than the " other guy". You need to know what your talking about. When you can educate them a little about the type of algae they have and exactly what to expect out of your roof cleaning you will be all set. Then you just have to follow through with the proper application.
I could never find any conclusive data that supported higher utility costs during some months because of staining. I have removed all references to it from our site and marketing. The theory that a algae blankets the shingles granule's to the point where it does not repel the UV rays and causes attic "super heating" is interesting, but why make a claim that could cost you credibility. My experience is that it is not a motivating factor in deciding to spend the money to clean a roof.
We don't promote the mold "scare" or the potential health related issues for the same reason. HO's live with musty smelling basements for years which is a precursor to mold because of water leaks which puzzles me.
Moss does cause shingle deterioration due to rooting. Moss growth does motivate HO's for roof cleaning sometimes. We have cleaned shingles for preventative motives several times.

Exactly what I'm trying to say, Mike!
I know that getting customers is hard (I have been in the moving business for 19 years), but I don't want to be that guy who lists every possible reason for getting your roof cleaned even if it has not been proven. I have found in business, that being as honest and forthright as possible with the customer, the more they will trust you and refer you to their friends and family. After all, we all know word of mouth is the best form of advertising. If you get a job by scaring them into it and then they happen to find out later that some of the information that you told them was either a lie or unproven, they will never trust you again, they will never call you back for more work and they won't refer you.
On your website instead of listing all the questionable terminology and before and after photos, just have a picture of Mother Teresa standing on a roof with wand in hand.
If you shoot the roof with a temperature gun on a dark stained area and then on an area with no staining there will be a difference in temperature. I had a customer that thought roof cleaning only offered curb appeal and was not so interested until I showed him the diff in temperature and I closed the sale. By the way I like your splat.
I think the ARMA technical bulletin was written before GM was correctly categorized as a Cyanobacteria. Let's face it, most HO's are never going to understand this stuff. But, in my opinion it's good for us to know. The splat and a,hole comments were rich. This thread keeps getting better.
