This Is The Roofing Manufacturers Method Below: Check it yourself. It says not to pressure wash!

You have probably heard all the new fad GO GREEN Biofoam Bio Degradable Eco-Friendly roof cleaning pitches that have cropped up recently. Or the $$ making Roof-A-Side type programs, that keep guys walking on your roof once or twice a year to maintain clean appearances?

They try to convince unknowing homeowners that chlorine bleach should not be used on roofing to clean with.

The reason is, they know that chlorine is the industry standard and what the manufacturers allow roofs to be cleaned with under warranty.

However, there are many, many real professionals cleaning roofs properly with chlorine-per manufacturer instructions.

So, these new start up companies try to get work by telling lies about chlorine use. But you won’t see them posting a roofing manufacturer that suggests their chemicals or pressure washing, because none do.

It’s their way to fool you into thinking you are helping save the environment!

What is more damaging to the environment? — chlorine, which is everywhere and turns back into plain salt when it dries?

Or roofing shingles in dump sites, because they only lasted a 1/2 life, due to improper cleaning methods? DON’T BE FOOLED!

Here are the facts from The Roofing Manufacturers Themselves.

It’s your warranty, you can listen to the green salesman and pressure washing guys, who can blast the discolorations [ along with your roofs granules etc ] off from your roof, or to those who make the roofing and honor warranties or void them. < Incidentaly, I am not against pressure cleaning! It is perfect for all exterior cleaning other than roofs. I have been a pressure washing contractor since 1978 — I just know better than to pressure clean fragile roofing. >

Here you go! I could easily supply more proof, but this is pretty obvious, I’d say.

First, gently disperse this solution on the roofing surface. Avoid scrubbing the surface, as this friction may loosen and remove granules.

With years of experience. it became clear to me that while pressure washing roofs made them look clean, damage was occurring on the roofs. Pressure cleaning machines can only be turned down so far and still accomplish roof cleaning and any amount of pressure, even as low a setting as 300 psi < 3000 to 4000 psi is what most pressure cleaning contractors use > will still remove around 15-20% of the granules that make up the color and protection of your shingle roof per cleaning.

Ugly black algae, left in place on the roof, eats around those granules and the rain removes them. Still eventually destroying the roof and spoiling it’s appearance and resale value. With tile roofs, pressure removes the glazing many tile roofs come with. Pressure also blows pieces of cement that hold the ridge-caps in place off into space! If your tile roof is painted, pressure will blow portions of paint off all over the roof, leaving it in need of an expensive paint job!
