Attached is a download right from certainteed that a homeowner gave to me. They asked me to clean their roof, and certainteed is going to pay for it. Their shingles are only 4 years old, and have black streaks on them already. Thought everyone would like to have a copy of this in their arsenal.
They make it sound so simple that a child could do it. You would think they would metion the safety needed or dangers associated with cleaning a roof. I can see how a solution that week could lighten a roof but not keep it completely clean for a long period of time.

The important thing is:
You see them suggesting chlorine.
You don't see them suggesting a "GO GREEN" "Pray and Forget" type product.
You don't see them suggesting Roof-A-Cide.
I'm sure they understand stronger solutions are needed on many roofs, but they are covering their butts, in case of a homeowner DIY chlorine injury - and still directing them in the chlorine direction!
Again-

My thoughts are the same as Chucks. In fact that is what I explained to the homeowner who called me. They needed to have their roof cleaned, and it was to be covered by certainteed. They wanted me to follow the directions that Certainteed sent to them. I explained what I use, and why it is diff. than what they say to use. I explained the safety precautions that need to be taken with our mixture, and why the shingle manufacturers would not be able to tell the homeowners to clean it themselves our way, because of the safety concerns.
Just so everyone has the tems right, we don't use chlorine. We use bleach or sodium hypochlorite. Chlorine is a gas. Sodium Hypochlorite is what the USEPA was getting all of the water treatment plants and water parks to switch to away from chlorine to save the ozone.
That is a great letter to carry around with you,thanks for sharing. Also chuck hit it on the head and A/C is right when nessacary we should be saying " Sodium Hypochlorite.

Your info is appreciated. It's odd how hard it is to get straight simple facts on this!
A search in Google "Differences between chlorine, bleach and sodium hypochlorite," do not get the answer. I know we use sodium hypochlorite and that's what my warning labels from pool stores call it. I had thought bleach, was a term generally associated with laundry? I had assumed chlorine and SH were 2 different names for the same item?
This is all I could find:
Chlorine 101: A Workhorse Chemical
Chlorine is one of the most abundant chemical elements on Earth. It is ubiquitous in soils, minerals, plants and animals. Seawater is a huge reservoir of dissolved chlorine weathered from the continents and transported to the oceans by Earth's rivers.
Chlorine is also one of the most useful chemical elements. Each chemical element has its own set of unique properties and chlorine is known as a very reactive element—so reactive, in fact, that it is usually found combined with other elements in the form of compounds. More than 3,500 naturally occurring chlorinated organic (associated with living organisms) compounds alone have been identified.
Chlorine's chemical properties have been harnessed innovatively for good use. For example, this element plays an essential role in public health. Chlorine-based disinfectants are capable of removing a wide variety of disease-causing germs from drinking water and wastewater as well as from hospital and food production surfaces. Additionally, chlorine plays a critical role in the manufacture of thousands of products we depend upon every day, from computer chips to crop-protection chemicals to cancer-fighting drugs. Some of these products contain chlorine, and others simply depend on chlorine chemistry for an intermediate step in their manufacture. As the ninth largest chemical produced in the U.S. by volume, chlorine is truly a "workhorse chemical."
Released From the Salt of the Earth…
Chlorine is produced industrially from the compound sodium chloride, one of the many salts found in geologic deposits formed from the slow evaporation of ancient seawater. When electricity is applied to a brine solution of sodium chloride, chlorine gas (Cl2), caustic soda (NaOH) and hydrogen gas (H2) are generated according to the following reaction:
As the reaction demonstrates, chlorine gas cannot be produced without producing caustic soda, so chlorine and caustic soda are known as "co-products," and their economics are inextricably linked. Caustic soda, also called "alkali," is used to produce a wide range of organic and inorganic chemicals and soaps. In addition, the pulp and paper, alumina and textiles industries use caustic soda in their manufacturing processes. Thus, the "chlor-alkali" industry obtains two very useful chemicals by applying electrical energy to sea salt.
…To a Chlorine Tree of Benefits
The Chlorine Tree is an interactive web-based tool that organizes the myriad products of chlorine chemistry by both chemical logic and benefit information. Explore the branches of the Chlorine Tree to discover how chlorine chemistry enhances modern nutrition, shelter, transportation and health and well-being.
Conclusions
Chlorine is one of nature's most common chemical elements.
Electricity applied to salt solutions enables the chlor-alkali industry to harness chlorine captured in salt deposits of ancient oceans.
Chlorine's chemical properties make it an extremely effective disinfectant and essential component in the chemical manufacture of literally thousands of vital products used every day.

I think Chucks earned a "Masters degree in Hell Raising" from the Roof Cleaning INSTITUE of America for all his studies of late no matter who he's pissed off! Would look good under his sig pic!

careful what you say!
I saw one guy get his changed to "Koolaid Drinker"
I don't need any more recognition as a hell raiser, than I already have, without a title change!
I get out of line occasionally and Chris PM's me and I agree to his suggestions.
Most of the time, the trouble I cause, is well deserved! Like this Roof-A-Cide guy!
I'm quite happy with
