Surface cleaner on roof?

[Ohio pressure wash]

I just watched a roof cleaning youtube video of a PW'er cleaning a roof with a surface cleaner. Personally, I consider it to be too destructive but being a SH guy maybe I'm a bit biased.

Just curious, does anyone actually do this?

The cleaner Times advocates it so that should be enough to keep legitimate contractors from doing it. I'm a SH guy myself.

We have a competitor that uses one on asphalt shingles. It leaves racing stripes.

Ive use it before on big commercial hotel roofs 28k-40k s.f. of roof. they just wouldnt be able to pay for that to be cleaned with SH. Oh and it was a flat tile almost paver looking roof. not steep at all but about 12 yrs of grime on it. Never use it on a shingle roof period!

I have also used them on Roofs, commercial only. Metal roofs on industrial buildings.

I wouldnt recommend in Asphalt shingles.

I used to used then on tile roofs back in the day. Actually still do if the landscaping is worth over 50,000.00 and that's not uncommon down here. It's just alot more work than using chem...

Back a 4-5 yrs ago this was about the only way we Cleaned Tile Roofs. It was back breaking work and never really got it all cleaned. We always had to follow up with using a wand on them. Now all we do is Non Pressure Roof Cleaning. :yes4:

I remember years ago making fun of the guys using chem to clean roofs, I thought they were crazy. However, I finally saw the light and work smarter not harder. It was no fun dragging the surface cleaner across the roof while trying not to slip. Yeah Larry nothing worse than finishing a roof and then having to go back over the whole thing with a wand.

It works real well on tile roofs, if done right it will not harm anything but your back. The cost of roof cleaning with a S/C was real cheap as all you needed was a downstreamer and maybe 10 gal of chemical for a standard size roof.

I probably should have clarified this or excluded hardy surfaces. I don't think anyone is worried about a SC damaging concrete, tile or metal roofs.

What about wood?

I would not use but the pena advocates using a pressure washer on wood.

 

[Larry Millette]

I've acually used a SC on wood boat docks and decks and haven't had any problems. As long as you keep it moving along at a steady pace and don't slow down or stop they come out fine. (@ least mine have). Here is one example of a wood deck that we used a SC on.

Nice Work Larry

I have not tried a surface cleaner on wood, I am guesssing if you went parallel with the boards it would probably be ok rather than across.

I am guessing the overlap might not be as noticeable on the wood?

Thanks.
