Now all of you can see the type of boneheads that are all around Palm Beach. 99% of my calls start out with "I need my roof pressure cleaned/washed." Its irritating to say the least. Then you get people that freak out if you say bleach, like its going to melt their roof. As we have said already, its in our water supply, pools, bathrooms, and washing machines but if its sprayed on the roof it becomes a huge deal. Chemical cleaning is still unknown to many and that is the only reason it is feared for no reason. If chemical cleaning was as popular as pressure cleaning is we would all be better off.

Wow, not over here in Tampa! People are scared Chitless of pressure washing any roof. In fact, once, maybe 10 years ago, we had a pressure washer on our truck only for driveways, etc. It scared my customers  so bad we removed it! 

Chemical Roof Cleaners usually make their mix in 100 gallon batch or larger.

From reading: Per 100 gallons the are typically starting out with 60gal water 40 gal SH!. That's 40 gallons! for tough jobs some add powered bleach that is 65% strength!
The adding a very concentrated soap to help thinker or allow the solution to stick rather than run off the roof onto the environment. But what happens if it rains, or the morning dew, or over time...were do these chemicals go??. This is their big problem, stopping the product hit the ground, patio, trim, furniture etc.

Readers/chemical contractors perhaps you can chime in the mixe's used.

NB: household bleach is 1%, Pool Chlorine is 10%. Chemical roof cleaning with chemicals in tanks are whole new ball game!

That's 20, 30 40 gallons of SH applied to one roof/property!. this is far too much! Think about all the houses down the street that back up to a lake...I would not eat those Bass for sure!

Traditional pressure cleaners add chlorine through a downstream chemical injector that sucks the chlorine out of a 2.5 gal jug this is a very low amount... This should NOT be confused with tank set up chemical roof cleaning. These two applications are VERY different in strength by huge amounts!

Referring to chemical roof cleaning as a bit of bleach that is harmless is a gross understatement in relation to the chemicals used and their strength applications

Perhaps you can reply as to the exact strength of product you are using, as this should be disclosed to home owners, they need to know, especially since roofs cost 20k, 30k, 40-50k even more money.
The roof is the single biggest asset to the home, and its job is to preform 20-30 years or more. However if you are applying strong chemicals to it every 2-3 years it sure sounds like the roofing market is a good business to be in. What we do see is a lot of roofs failing in the valleys or collection areas.

I am surprised that your above chemical roof contractor above, does not know what will happen to his shingle test, yet he applies it to roofs, and I might add that he applies the chemical to metal, nails and other roof accessories while he is doing his test. Roofs can leak from rusty nails, especially in valleys, and with asphalt shingles as the nail is just under the tab, and under that...only 30lb tar paper that is a thin minimum membrane. Perhaps stick your hand in it too, or take a good wiff of it.
Also it turns Roof Tile dull and brittle so the next person walking on the roof breaks a lot of them easier. As for Cedar shake it dries out the wood, sucks the natural tannins out, and the shake start curling from drying out very quickly

I consider this type of roof cleaning nothing to do with pressure cleaning at all, yet your lic workers comp classifications are the same for very different work on a pitched surface that is very slippery.

Have any of you made a workers comp claim for chemical roof cleaning under your current classification...by the time its get to pay the damage, the insurance company could have a reason 'not to payout'. believe me...I don't wish this on anybody, but it needs to be addressed for safety and also liability which would fall on the customers/homeowner behalf.

I think chemical roof cleaning needs more guideline's from local and state, there are no regulations and kids are mixing up chemicals in their garage, storing them, driving them around in big tanks on questionable vehicles/trailers with little training on anything really...its a big worry. Swimming pool companies & chemical companies handle the same chemicals however they are treated different ...why?, and they are not atomizing them into the atmosphere 20 feet up with wands

I am sure you would not wash your vehicle with your chemical...so why a 30k roof?

I hope you can address these issues, but I feel you cant because the chemical is SH that you use, and we all know what it does...its not bio degradable, perhaps your techy soap is that's added to it

Also in my video I was using under 500 psi then I turned the unloaded valve down more, as I stated it was low low pressure NOT HIGH PRESSURE WASHING, and did not harm the roof, perhaps I will go back to the job as its been a year and check it out. The house backed up to a major canal connected to south Florida water management...even more reason to use water only.

I also see a lot of areas off this forum are private especially related to chemical mixing...why?

If you would like to know more about my process and equipment I would be more than happy to advise on how to build it and operate it, without any fee for my time.

Here is some great information about how a high flow pressure washer works. Notice that the More Flow, the more IMPACT  In case you didn't know, it is IMPACT that knocks the granules loose 

Pressure and flow

Pressure washers use the impact of the water to break the bond of the dirt to the surface you are trying to clean; the higher the pressure, the greater the impact. The type of nozzle you use makes a huge difference in how much impact your pressure washer creates. A zero degree tip gives you the full impact of your pressure washer but is almost useless for cleaning because it hits such a small area. A 15 degree nozzle increases the area you can clean at one time, but reduces impact by 70%. A 40 degree increases the surface area cleaned further, but has 88% less impact than a zero degree nozzle. This is why a turbo nozzle is so effective; for it is a 0 degree nozzle rotating thousands of times a minute creating a 25 degree cone of full impact.

The amount of water, or flow, a pressure washer puts out makes a big difference in cleaning. The flow is what carries the impact to the surface. The more flow, the more impact; there is a direct relationship. A 13 HP pressure washer putting out 4000 PSI at 3.5 gallons a minutes flow has one third less impact than a 20 HP unit putting out 3,500 PSI at 5.0 gallons per minute. Moreover, flow is what is needed for effective rinsing. This is especially true when cleaning large open surfaces, like driveways; or quickly rinsing vehicles in truck washing operation.

Cleaning units

A pressure washer pump creates a positive water flow, and by restricting that flow at the nozzle creates pressure. The more horse power driving the pump allows more flow to be pushed through the pump and the more pressure to be created at the nozzle.

Chemical Roof Cleaners usually make their mix in 100 gallon batch or larger.  No, not really.  I can see you found a mixing chart that was based off of a 100 gallon chart, didn't you?  The 100 gallon chart is so the numbers work out easily for mixing whatever you need.  If you were looking at a 65 gallon chart, mixing wouldn't be as quick and simple mathematically, thus the 100 gallon chart. 

From reading: Per 100 gallons the are typically starting out with 60gal water 40 gal SH!. That's 40 gallons! for tough jobs some add powered bleach that is 65% strength!  Umm, never seen 65% liquid bleach.  Probably 99% of the people cleaning roofs with SH use 12.5 % SH and then dilute it with water.  I'd like to find 65% SH...you could do a lot more jobs  between refilling your SH tank.
The adding a very concentrated soap to help thinker or allow the solution to stick rather than run off the roof onto the environment. But what happens if it rains, or the morning dew, or over time...were do these chemicals go??. This is their big problem, stopping the product hit the ground, patio, trim, furniture etc.  If you just mixed water and SH it would run off the roof before it had a chance to do its job.  The surfactants thicken the mix so it clings in place versus just running off the roof.  If you're really interested in how we do things, ask, don't be passive aggressive.

Readers/chemical contractors perhaps you can chime in the mixe's used.

NB: household bleach is 1%, Pool Chlorine is 10%. Chemical roof cleaning with chemicals in tanks are whole new ball game!  Normal household bleach is not 1%, it is 5.25%, 6% and 8.25%.  If you go looking for higher strength bleach you can find it from ~10 to 15% strength, but as stated above, the majority is 12.5 %.  If you're going to be spouting off information, please at least take the time to research the information you are posting.  If you don't know what you're talking about, it just makes your position that much weaker spouting off incorrect information on a forum where people know.

 That's 20, 30 40 gallons of SH applied to one roof/property!. this is far too much! Think about all the houses down the street that back up to a lake...I would not eat those Bass for sure!  Wow, more misinformation.  Go read up on how bleach works.  Oh, here is the information Mr. Bergman wanted you to read, copied directly from a bleach website - "S H and S hydroxide. Environmental Commitment: The surfactants in this product are biodegradable. The bleach in this product rapidly breaks down almost entirely to salt water. Contains no phosphorus."

Perhaps you can reply as to the exact strength of product you are using, as this should be disclosed to home owners, they need to know, especially since roofs cost 20k, 30k, 40-50k even more money.

However if you are applying strong chemicals to it every 2-3 years it sure sounds like the roofing market is a good business to be in. What we do see is a lot of roofs failing in the valleys or collection areas.  You may need to do some more research again.  I hang out on the SoftWash Systems forums mostly and pretty much all those guys give a 5 year warranty on their roof cleaning.  Sorry, I asked you this before and you evaded my question...do you do yearly follow ups?  I have a friend in Portland that has been having his roof pressure washed twice a year because the stains keep coming back with pressure washing.  I introduced him to a bleach based roof cleaner in the area and he will do the job and give him a 5 year warranty.  Can your method give that kind of warranty?

I am surprised that your above chemical roof contractor above, does not know what will happen to his shingle test, yet he applies it to roofs, and I might add that he applies the chemical to metal, nails and other roof accessories while he is doing his test.  Wow, nice way to try and twist my words there Chris.  What respect I had for you is quickly dropping.  I know what will happen to a shingle on a roof cleaning...as always, NOTHING...on a roof cleaning about 95-98% of the SH is inert by the time the cleaner pulls out of the driveway.  Did you know that?  Let me give you a little lesson on bleach.  NaOCl, that is the chemical makeup of bleach.  Na=S=salt, O=Oxygen, Cl=Chlorine.  Want to know how to make bleach?  Take water, mix in some salt, and put an electrical charge across it.  You'll see the mixture start to bubble.  The bubbles is the hydrogen gas escaping as it breaks from the oxygen it is bonded with in the water (H2O...notice the H is missing in the NaOCL formula?)  Granted you'd probably only get <0.5% strength SH like this, but you get the idea.  Now, back to where you were twisting my words...I know cleaning a roof with SH will not harm the roof or nails or anything else you mentioned because bleach is rendered inert quickly after it is applied.  I was going to put the shingle in the bleach for a week at the full 1 gallon strength even, not the  diluted mix we use on various surfaces.  I didn't get to do this today because the weather was a bit nasty, but tomorrow (ok, today, Sunday) will be a brighter day hopefully. 

Roofs can leak from rusty nails, especially in valleys, and with asphalt shingles as the nail is just under the tab, and under that...only 30lb tar paper that is a thin minimum membrane. Perhaps stick your hand in it too, or take a good wiff of it.

I consider this type of roof cleaning nothing to do with pressure cleaning at all, yet your lic workers comp classifications are the same for very different work on a pitched surface that is very slippery.   cause and effect.  A pressure washer is similar to a gun, and when you pull the trigger you have water spraying out with force from your wand, and you have an equal and opposite reaction pushing back on the wand every time you pull the trigger.  I've seen tons of information advising people not to pressure wash off of a ladder because the pressure recoil has caused so many people that are pressure washing to be pushed backwards enough to lose their balance and fall off of ladders.  That same principle applies to being on a sloped roof with a pressure washer.  SoftWashing is just that, soft...~60 PSI is about the exact same kick as spraying a garden hose, which is pretty minimal, and much safer.

Have any of you made a workers comp claim for chemical roof cleaning under your current classification...by the time its get to pay the damage, the insurance company could have a reason 'not to payout'. believe me...I don't wish this on anybody, but it needs to be addressed for safety and also liability which would fall on the customers/homeowner behalf.  Nope, not a single issue, and I pray to God there never is, for any of us.

I think chemical roof cleaning needs more guideline's from local and state, there are no regulations and kids are mixing up chemicals in their garage, storing them, driving them around in big tanks on questionable vehicles/trailers with little training on anything really...its a big worry. There are plenty of guidelines from multiple agencies Chris...again, go do your research.  Swimming pool companies & chemical companies handle the same chemicals however they are treated different ...why?, and they are not atomizing them into the atmosphere 20 feet up with wands Again, go do your research.  We're not atomizing (go find a dictionary and look it up), we spray pretty much like a flat spray on a water hose garden nozzle, which is far from atomizing.  Why do you keep trying to spew out fear tactics against bleach.   Speak out honestly against bleach however you want, but don't try to make it dramatic by using incorrect terms. 

I am sure you would not wash your vehicle with your chemical...so why a 30k roof?  I would wash my vehicle with a bleach solution if my vehicle was covered in the same organisms that cause a roof stain.  People do have metal roofs, they do get stains as well, and they do get chemically treated without harm. 

I hope you can address these issues (addressed already, by multiple people), but I feel you cant (but you're wrong)  because the chemical is SH that you use, and we all know what it does...its not bio degradable, perhaps your techy soap is that's added to it - Again, directly from the bleach website that Mr. Bergman linked above - S H and S Hydroxide.

The house backed up to a major canal connected to south Florida water management...even more reason to use water only.

I also see a lot of areas off this forum are private especially related to chemical mixing...why?  Most professional forums have a public side where guests are welcome to participate, and a private section for the members to discuss whatever they want to discuss.  Why are you making it seem like a bad thing here when it is an extremely common occurrence on forums?  Do you not visit professional washing forums and just not know any better, or are you just trying to make it sound like a shady practice?  Quit with the drama.

If you would like to know more about my process and equipment I would be more than happy to advise on how to build it and operate it, without any fee for my time.  I was tempted to say yes and ask for everything, but I realized I'd be wasting my time.  Again, as stated previously in these forums and links to the ARMA website, pressure washing is strongly discouraged and can harm roofs and cause homeowners to lose their roofing manufacturers warranty, and again, bleach is what the roofing manufactures and the ARMA suggest (the ONLY thing they suggest), not high pressure water, so no, I'll save you the time and pass on that offer.  I don't want to harm customers roofs so I'll stick with what the ARMA and roofing manufacturers suggest, bleach, not high pressure water.  I don't want to prematurely age and damage my customers roofs using high pressure water.  There's a reason I've never had a claim against my insurance, I don't use practices that damage customers' roofs.

And you do seem like a friendly bloke, so hopefully the next video you post will include some PPE.

Excellent points Troy! Here at the RCIA, we use facts, not just talk or "I THINK" I kinda feel bad to speak with such anger to this "Guest" but he came here looking for trouble, not help, facts or answers to legitimate questions, so he got me going!

Thanks!  I do my best not to resort to angry answers because I don't want to get into a mud slinging contest, but if not angry, I'd say annoyed? :0)  It really does make me angry though when people use fear based tactics versus legitimate reasoning with factual evidence to back it up to push customers into a sale.  I abhor dishonesty.  I'm not saying this guest is a liar, but I'd say he is spouting off information without doing research to see if there is official documentation backing it up.  His "I think" is just a weak legal loophole if anybody wanted to take him to court so he could say "See, I said I only 'thought' this was the right way, I never said it was researched and factual.  It was only my opinion..."  His "I think" just weakens his argument in my eyes.  The thing is, if anybody were to take a copy of his video he does say things in there that could probably leave him legally liable, such as around the 20 second mark where he says the ARMA approves high pressure washing methods on roofs, but he can't post a link to an ARMA website saying this because it just isn't true.  If it is true I've been unable to find it anywhere, but since he won't post this link, I have to maintain my original opinion that he's again speaking without fact and falsely misleading customers.  He says he has been cleaning roofs for 24 years but his website looks like it was made up in a day and there is no gallery of before/after pictures or photo's with a date on them dating back to when he started.  Did he clean his first roof 24 years ago and just start trying to do this professionally a few weeks ago and using that first cleaning as another loophole?  Heck, if I did that I could add almost a decade to my time when I started cleaning roofs from my first actual cleaning to my first professional cleaning.  He said earlier that he has driven 1.2 million miles for business, but I have to question that too.  My dad was a professional trucker and the 1 million mile safe driving award was given after 10 years of safe driving and my dad had a couple of them back to back.  If it took 10 years for my dad doing nothing but driving 40+ hours a week to reach 1 million miles, how does he reach 1.2 million in 24 years?  He is spending half his day or better driving so either he has few people as customers that live far away or several customers not too far away, and he is only on a roof for 30 minutes or less for a cleaning...and he dares to call us "splash and dash" operators?  Now did I catch him in a lie, or did he just say he did 24 years of cleaning and guesstimate he drove 500,000 miles each year, or did he again not take the time to do the research before posting?  The more he posts, the more items I see that are questionable, unsearched or just "I think" LOL

Using 500psi and the unloader turned down is not soft washing. Calling it low, low, low pressure is still power washing, not recommended by the shingle manufacturers.

We use no pressure at all and chemicals recommended by the shingle manufacturers and prove it with these documents.

Thanks gentlemen, I appreciate the compliments...(and look, no high pressure water)

I had a couple of other remarks but they were less professional than I wanted to post so I removed them.  I'm trying to not let myself get pulled down to a mudslinging level, although it is tempting, even after he twisted my words.

I will reply...again...I was not using high pressure...I was using low low pressure,  cleaning with water only...NO CHEMICALS

So what is high pressure cleaning...usually 2000, 3000, 4000 psi. from a portable pressure cleaner that is designed for cement and harder surfaces.

I was using under 500 psi, then turned the unloader valve (regulates pressure) down a half turn again as the water volume was doing a incredible job, so lower psi is even better,  as you can see via my video. Then I had the spray fan a foot away from the Roof. The low pressure was what was in the hose as per my pressure gague at the head of the pump, also by the time its gets through 150 foot of hose its lower again... so out of the hose/gun, through the tip and then another foot away from the roof you can diminish the psi by more than half that again!...probably more. Its was all water volume and a lot of water I might say to clean the roof like new, rather than turn it another color and leave the debri there. turn this water volume was 30hp via a tak water system as we know my water supply was not from a spigot

I was pumping 12 gallons a minute with a very sharp flat spray pattern tip,  custom made by spraying systems , a tip that perhaps you have never used before, or a rig like mine that was pumping it either, actually it was custom built...so you cant comment on my system at all.

Your comments are just speculation on what you think, and its obvious you want to try and prove my system is high pressure doing roof damage...well its not. Got it ???

Its clearly visible I can spray my body, legs, hand to prove how GENTLE the water is...AGAIN LOW LOW PRESSURE NOT HIGH PRESSURE...GOT IT???

Perhaps another video is in order to show you close up at the spray tip / roof surface, and then the gutter collection area below.

I am correct, no granules were blown/scared off the roof,  this system is superior to Chemicals for sure...you just dont want to believe this...I cant help stubbornness that you dont want to think that you can clean a roof without chemicals.

As for tile roofs and cedar shake, metal etc you obviously have no argument at all and that's 75% of other roofs out there that don't need to be shot with chemicals for no reason at all other than you don't want to work harder on the roof, get wet and clean the debri off the roof gutters etc.

Again No granules were removed...this is far superior to applying corrosive S Hydroxide and Chlorine TSP gain soaps etc...soon you will look like pest control applicators with red skin and rashes. What does your wife say to you??? what about the soil/plants/animals/eco-system?...you don't care obviously. The shear gallon's of chemicals per roof you are applying are excessive at best. People don't want that..they tell me

Go tell the home owner whats in your tank, the chemicals and its strength before you apply...watch them slam the door. You are not being up front on the  concentrations of your chemicals, Home owners have a right to know. Home owners have a right to know long term effects of roofs, however you don't have this data, or care to test, long as the roof looks clean and you get paid...NEXT Roof right?

You do you way I will do mine,  in 15-20 years your roof will be gone...from corrosive roof failure, because you can't expect to keep dousing the roof over and over again with Chem and expect to extend the service life..if so enjoy the Kool Aide!
