Chemical free roof cleaning: REPORT: What is this? What does the roofing manufacturer suggest? They should know!

I just did a Google search for Charlotte Sarasota County Roof Cleaning and I found  this "Chemical free roof cleaning" { Feb 16th 2011 }

I went to the persons post and it was a pressure washing guy, using a Cement Surface cleaning machine on a tile roof. I have had a pressure washing business since 1989, but I would never damage someones roof by using pressure to clean their roof! Lastly a super strong cement surface cleaner, which attaches to a 3000-4000 lb pressure washing machine. His picture showed him blasting a tile roof with it, but, imagine if he used that monster on a shingled roof? Bye Bye roof granules and probably some of the shingle tabs as well!

Even on tile, many have been painted, or have a factory glazing. A pressure washer / cement surface cleaner will take much of both off, as well as small pieces of the softer cement that holds your ridge caps in place.

No, the roof cleaning industry, as well as the roofing manufacturers and their warranties are not likely to approve of this "Chemical free roof cleaning"

The chemical [ chlorine ] is needed to kill the algae, mold, mildew, fungus that is on your roof. I know as a pressure washing company, that without coating the algae with chlorine,  it will remain alive-though not visible and be right back next summer!

With a proper "Safe Soft Wash" on your roof, you will usually get 4 years between cleanings.

I will use my cement surface cleaners on driveways and parking lots, not to jet blast roofs!

Bergman's Non Pressure "SOFT WASH" Roof Cleaning, Florida

This is Chuck Bergman's  Roof Cleaning and Pressure Washing Information page.

We are a father and son only business and specialize in the cleaning of roofs offering the newest and only "approved" [ by the roofing association ]
" NO PRESSURE " roof cleaning system.

For asphalt shingle roofs, this system is a must and can add years to your expensive roof's life!
Pressure cleaning a shingled roof removes a large percentage of the granules, that make up the surface and color of your roof.
Many Pressure Washers advertise "NO PRESSURE" but don't actually own the equipment. They simply use their pressure washing machine's chemical injector and end up using "SOME" pressure anyway and explaining [ if you see them do it ] that they turned the pressure way down.
You can't turn a pressure washer "down" enough to not blow the granules off!
ANY pressure will remove much of your asphalt shingle granules! Click below to go to the roofing manufacturers association and read for yourself it's simple clear statement about pressure "HIGH PRESSURE WASHING SYSTEMS FOR ALGAE REMOVAL SHOULD NOT BE USED" http://www.asphaltroofing.org/pdf/tb_217.pdf

Of course, we do have state of the art pressure washing equipment as well for houses, pool enclosures, decks, driveways etc.
In fact, with our many years of experience, we have found that a pressure washer that puts out a larger flow of water [5.6 GPM]
and less blasting pressure 2000 - 2500 psi, gets the job done better than a high blasting pressure [3000 to 4500 lbs is common and lower water flow [4 GPM] or less.]

Even tile roofs benefit from our "NO PRESSURE" system, in that high pressure will send small pieces of tile and cement holding your ridges in place, off into space!
Also, if you have a finish on your tile roof, such as a solid paint coat or a glazing, high pressure can peel the paint or dull the glazing.

On anything but roofs, pressure is needed, so we also have a 3500 psi machine and a 2500 psi machine with us at all times to use as needed.

Another reason to hire us to clean your roof is - You may see competitors who say they are "Plant Friendly" or "Water plants well" WE EITHER WATER CONSTANTLY & OR COVER ALL OF YOUR PLANTS WITH TARPS.
That's as "PLANT FRIENDLY" as it gets in this business!  Because this offers the maximum protection!

My son has worked continuously with me since 1994. So, if you have Black Algae on your Roof that needs removing, whether for:

#1. Health reasons [Those who suffer respiratory ailments are adversely affected by the airborne mold spores
#2. To stop the deterioration of the roof [ algae eats constantly]
#3. Aesthetics [ many beautiful homes have their appearance spoiled by black, discolored roofs]
#4. Because your homeowners association requires it.
Give us a call! You will be glad you did!

All work is done by either the father or son, there are no employees.

So, you won't get a new guy in training ever with us!
