The Roof Cleaning Institute Of America Training & Certification Forum
"Find A Certified Roof Cleaner Directory"

You are so full of it Smitty.  What is your back ground that makes you such an expert?  I have been cleaning tile roofs for 19 years and have never stripped the glaze from tiles.  I am even referred to tile roof home owners by the makers of the tiles on their roofs.

High pressure washing will strip the glaze from the tiles.

Actually, the only thing I use is SH and TSP...I've just been doing some research on what is proper according to the tile manufacturers (this is our primary roofing here in sunny Florida) however, I  have come across a lot of contradictions in what the company is advertising they use and what they actually use! Clarification is all I needed. Thank you.

"We don’t use mortar or glaze removing muriatic acid on your roof, or just spray Chlorine on it either.
Strong Chlorine and Sodium Hydroxide solutions have been known to actually strip the glaze from your tiles"...What does RCIA recommend me using? Or are you saying that I should use a Sodium Hydrochlorite? Hmmmm...confusing please explain

 These are actual posts I am finding out here and would like to respond to the HOME OWNER when asked about it. They are the whole reason I have been cleaning roofs people! I do not wish to hide what is used. I wish to explain how, what, and why it is used. Especially from the Certified Roof Cleaners in the same state I am in. Sodium Hypochlorite (SH) is, by the EPA, known as chlorine. I cannot lie to a customer-I will give them the choices of what I am using and what the others are using-Let them make the choice, but an informed one not a hidden-behind-word play one.

 Welcome Smitty, I see you made it over here, to this Forum.

TSP is an awesome cleaner, but you have to be careful! Some Tile Roofs are painted, and the TSP can dull the paint!

 Thanks Chris! I'm not as savvy on the computer as I am on the roof  but I finally figured it out...thanks for the heads up on dulling the paint too! What other product would you recommend that won't dull the roof, Chris? I've heard of the Gain but what I'm understanding is that it is merely to mask the smell of hte SH. I'd appreciate any help you can give me here, Chris as I respect your knowledge, and value your opinion.

 Well Smitty, it seems that using additives to the mix is kind of like asking what kind of deoderant you use, everyone has their opinions!

NOTHING equals TSP (or even comes close), as far as sheer cleaning power goes. For a Bare Cement Flat or Barrel Tile roof, it is the chit.

Do NOT use TSP on Clay Tile or painted tiles, but other  then that, you are good to go with it.

I do not like ANY surfactants (not including TSP) on glazed tile roof (makes them too slippery)!

But, on Clay or Cement Tile Roofs, it is not as much of a problem.

Gain is a powerful soap (surfactant), as well as a chlorine masking agent, at higher concentrations.

 I use AXE what do you use?  LOL I really appreciate that info Chris.

 It depends Smitty. I am single, and if I am by myself, I use deoderant. But, if I am going to meet with a girl, I NEVER Ever use any deoderant, or anything with a smell in it.

Here is why. It will mask the Phermones, that could possibly have attracted a girl to you w/o her knowledge, or yours either.

So Chris you are saying... 50/50 mix for tile roofs? No surfactant, no tsp, Just straight SH and Water. The Duke Nukem mix?

---

 NO! WE never go 50/50 for tile roofs, much too strong, cleans great, kills plants better 

60 water 40 sh is the most we ever go, but then we is in Tampa Florida, EH 

The sh here is fresh, and very strong.

Very Strong?  What % SH are you getting down there.  We can get only 10 or 13% in Houston Texas.

 We only get 12.5 percent, but there is a world of difference between FRESH 12.5 percent, or OLD 12.5 percent.

Plus, we not only get it fresh, but we get it from a place that almost always runs their tanks down to nearly empty, so the FRESH SH is not compromised by adding it to OLD SH in the tanks.

Florida is the land of swimming pools, and when it rains, the SH in a pool is diluted, so people need more of it, and keep the SH here pretty fresh.
