We know your roof is expensive and you probably don't want to have any new chemicals tested out on your roof?

Non manufacturer cleaning methods may void your roofing warranty, according to the information in their links below, so we just clean them as the manufacturer says to.

Then we get no lawsuits!

The main manufacturer recommended chemical is what most people call bleach. { Chlorine - Sodium Hypochlorite }

Is bleach truly green and eco-friendly?

Yes I would say it is. Chlorine bleach is Sodium Hypochlorite *look at the ingredients in your laundry bleach* and is made from common salt. It bio-degrades back into salt.

Bleach is chlorine and we all drink it in out tap water, soak in it in our showers and tubs and swim in it in our pools.

AT LEAST WE ALL KNOW WHAT WE ARE DEALING WITH, WHEN IT COMES TO CHLORINE. NOT SO WITH UNKNOWN CHEMICALS CALLED "GREEN"

The only real danger from chlorine, is if an unqualified roof cleaner does not care for your plants, directly below the roof edge, he can burn a line in your vegetation.

We take professional precautions, before, during and after cleaning all roofs, so this does not happen.

HERE ARE THE FACTS FROM THE MANUFACTURERS ETC:

Below are the only manufacturer suggested chemicals I have been able to find on any manufacturer website, bulletin, etc. Some 'alternative chemical users" claim "Approved" but do not supply manufacturer links to prove it.

From GAF Roofing Manufacturers about black algae removal:

http://www.gaf.com/Documents/Algae_Staining_on_Shingled_Roof_Surfaces_-_Steep_Slope_Techn-43-808-v3.pdf

Below is a partial "cut and paste" excerpt from the above link: GAF Roofing Manufacturers on how to clean a roof:

"If a new roof is not an option, GAF recommends cleaning the roof with a special mixture. That mixture is: water, bleach and TSP"

"What NOT To Do! Do not power wash the shingles to clean the shingles. Some roof cleaning companies offer this service. However, it is not recommended."

From ARMA roofing manufacturers Association-how to clean roofing.

http://www.asphaltroofing.org/pdf/tb_217.pdf

Below is a partial excerpt cut and pasted below from ARMA:

"Algae discolorations to remove from roofing surfaces, applying a solution of chlorine bleach, trisodium phosphate, {TSP} and water. Solutions for these ingredients depend on the amount of discoloration. Solutions range to one cup TSP and 2.5 gallons each of bleach and water. First, gently disperse this solution on the roofing surface. Avoid scrubbing the surface, as this friction may loosen and remove granules. Caution! High pressure washing systems for algae removal should not be used."

Owens Corning Roofing manufacturers says the same thing:

"USE CHLORINE and TSP" "DO NOT USE A PRESSURE WASHER"
Corning info in link below.

This one from the ARMA says not to allow anyone to apply any

*after coating*

such as Algae-cides, Fungi-cides, copper, zinc, or other treatments - not anything!

http://www.asphaltroofing.org/pdf/tb_227.pdf

SO, ROOFING MANUFACTURERS SPECIFY ONE MIX TO CLEAN WITH - CHLORINE BLEACH & TSP.

THEY SAY SPECIFICALLY NOT TO APPLY ANY COATINGS AT ALL AFTER CLEANING.

NOW YOU HAVE VERIFIABLE FACTS WITH LINKS TO MAKE DECISIONS WITH. NOT JUST SALES TALKS!.
