WE HAVE HAD A FATHER AND SON PRESSURE WASHING BUSINESS SINCE 1994.

I HAVE OPERATED THIS BUSINESS IN CHARLOTTE COUNTY FLORIDA AND S. SARASOTA COUNTY FLORIDA SINCE 1989.

WE PRESSURE WASH ALL BUT ROOFING.

WE CLEAN ROOFING USING THE MANUFACTURER SPECIFIC METHOD THAT IS OUTLINED BY THE MANUFACTURERS BELOW.

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 GAF 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:
 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-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, and water. Solutions for these ingredients depend on the amount of discoloration.
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"

So, those who manufacture your roofing and warranty your roofing are the folks to listen to!

Not those who pressure wash roofs, or try to sell you a so called "Green" Eco-Friendly" chemical.

We clean roofs ONLY by the roofing manufacturers methods, so your warranty will not be voided!
