Do not scrub. -------------------------------------------------------------------------------------------------------------------------------------- ARMA TECH BULLETING CUT AND PASTE After Cleaning Coatings "Field Coatings" "ARMA strongly advises caution when considering the application of any type of field applied coating over installed asphalt shingles. There are many types and formulations of roof coatings so it is important to always consult the shingle manufacturer before proceeding with any type of coating. Be aware that some asphalt shingle manufacturers specifically disallow field coating of their manufactured shingles. Additionally, state or local building codes may not approve this practice as the field applied coatings will drastically change the aesthetics of the roof and may change the performance characteristics of the roof assembly. Problems reported after asphalt shingle roofs have been field coated include unsightly curling and/or cupping of the shingles which may lead to premature failure and leaks. In addition, non-permeable roof coatings may create a vapor retarding layer; if this occurs, it increases the possibility of rotting of the roof deck caused by moisture accumulation in the attic space. It has been suggested by some that the use of field applied coatings over existing asphalt shingles will produce overriding benefits to the home owner — such as longer roof life, energy-use reduction (solar reflectant versions), or remediation of small roof leaks. There is little or no available documentation showing the extent to which the field coating of asphalt shingles provides any of these benefits, but the risks and concerns mentioned above remain very real. When considering coating of installed asphalt roof shingles, be sure to: *Obtain approval from the asphalt shingle manufacturer before proceeding with a specific roof coating. *Check with the local building department to determine whether this application is allowed" THE ACTUAL LINKS TO THESE MANUFACTURERS, WHERE I CUT THE TEXT FROM ARE HERE- http://www.bergmanpressurewashing.com/Manufacturer_Specifics.html

Chuck Bergman Florida Certified Roof Cleaning and Pressure Washing. 941-698-1959 Charlotte/Sarasota County FL

There are many pressure cleaning companies around. They come and go by the dozens yearly in North Port, Port Charlotte, Englewood, Rotonda and Venice Florida. There are only a hand full of actual "Roof Cleaning" companies. That's because roof cleaning requires all different equipment and there is no need for a pressure washing machine on the job! The roofing manufacturers actually say "DO NOT PRESSURE WASH" they products on all their websites I am aware of. You can read what they say here-

{MAY 26 2017 UPDATE OF LINKS. SOME URL ADDRESSED CHANGED. BELOW ARE THE CURRENT ONES. The link below takes you to a page on my website, with live links to roofing manufacturers, that all say to clean roofs with the method I use! They all also say specifically "DO NOT PRESSURE WASH"

Often, to try to turn homeowners away from cleaning their roofs as specified by the manufacturer, shady pressure washing companies and "Do it yourself" homeowner designed products, will try to downgrade the manufacturer method, by making childish statements like "Don't hire some guy to squirt bleach on your roof" or Don't get a cheap bleach job" etc. They don't want to carry all the extra equipment and don't know how to apply the specified bleach / TSP formula specified to be used by the roofing manufacturers, so they tell scare stories and lie, saying we use pure pool chlorine etc. The maximum amount of chlorine bleach ever needed to clean any roof is 3%-5%. That is a fact!

Other competitors, who are trying to make a go of it in the roof cleaning business, jump on the "Eco-Friendly" "Go Green" Bio-Degradable" band wagons. { Again, the roofing manufacturers specify bleach and none of them I have ever seen, suggest any of these new, SO CALLED Green products. Most claim to use biodegradable, Eco-friendly, Natural, Non-toxic, Organic products. First off, if you ask what is in their "Go Green" concoction of chemicals, you will not find out and it is not on the labels and the guy who comes to your home does not know what it's made of either. They are called "Proprietary Ingredients" Like the Colonel Sanders Fried Chicken Recipe!! The company making the product does not have to tell and the worker is not told.

Let’s look at the real meaning behind the sales pitches of Natural: Environmentally Friendly (Eco-Friendly Chemicals): Biodegradable: Plant Friendly.

Environmentally Friendly (Eco-Friendly Chemicals): Lead is an example of something known to be harmful to the environment, yet it is 100% natural, coming right out of the ground.

Biodegradable: The claim is usually made to sell consumers something many would like to see used, environmentally friendly products. In other words, broken down by natural processes into basic components. By this definition, most chemicals are biodegradable, the biggest difference is the amount of time it takes for each chemical to break down. We all know how long it takes nuclear waste to break down and be safe! Yet, it does in time, so it is actually biodegradable. None of these new chemicals will say how long it takes their chemicals to break down. I doubt, in all honesty, they have any idea themselves!

Natural: Note that this is not a legally regulated term! So it can be used for anything. Most times it is used to describe a cleaner that is manufactured from plants. Arsenic is from a natural plant. Many deadly compounds occur in nature. “All Natural”. What does that tell the consumer about their so called natural cleaning chemicals? NOTHING!

Try as you may, because there is no legal requirement to do so, these companies will not disclose what they actually are using. Instead, they will just throw around the terms above?

Consider also, because the roofing manufacturers do not want to pay to replace your roof, they have done the research and will cover your roof with the supplied roofing warranty -IF- you follow their very specific cleaning instructions and -IF- you listen to their very specific words "Do Not Pressure Wash"

So, don't let some fast talking salesman fool you with happy sounding terms like: Natural: Environmentally Friendly (Eco-Friendly Chemicals): Biodegradable: Plant Friendly etc.

Do like you do with your expensive new car, listen to the manufacturers! Keep your warranty intact!
