In the May 2013 edition there is what I consider a subjective article on roof cleaning. It's more along the lines of a three page advertisement. A friend brought it to my attention today. I'm trying to find a pdf of it but to no avail. Tomorrow I'll see if I can have scanned and post it.
The article goes against what we know works and the technical bulletins issued by the manufacturers.

Thanks for the link but this is not the one I was talking about. In the article they say not to use a pressure washer but this video which was distributed/published earlier contradicts their own belief system(BS).

I thought I had the right one. Sounds like they have a video for all their suggested ways of cleaning roofs. So, use a pressure washer and don't use a pressure washer. Kinda confusing huh?
