I never said I have PROOF of anything Justin, and yes it would be small-minded of me to put all confidence in what a homeowner told me.
I was just sharing an opinion and something I had experienced, not trying to pick a fight with the Chlorine Cowboy Club. My first comment was directed to MOSS, like the thread title, not algae and roof washing. I guess I can’t post an opinion without being dismissed with a Pffft/chuckle (sorry I called you a smart-ass Todd) and being called a dumb-ass and small-minded until I have at least 1,000 posts on here.
Aaron, nobody wants a fight here… there’s enough room for everybody here at WCR.
As I’m sure you’ll agree, the hardest part of selling a roof cleaning job is education. Here in the South, there’s a very small percentage of people that realize that their roof can be cleaned. 99% of the people think their roof is old and stained and needs replaced. It makes the education job a lot harder when people have the impression that bleach is harmful to their shingles. That’s why a lot of us take the issue so seriously.
There’s been a lot of bleach alternatives offered for roof cleaning, but so far, nothing has worked as well or been as safe as the ARMA approved solution of 12.5%.
Has anyone tried vinegar for roof moss? I was on a job site the other day and a roofing guy (of a very established company) was there to inspect a possible leak. He told the homeowner to spray the roof with vinegar to kill the moss and [U]not[/U] use anything like zinc or bleach.
Now the homeowner wants me to try this on her roof! Should I oblige for the sake of appeasing my curiosity?
i clean tile and grout and carpets, sometimes customers get very poor advice from their installer. they are installers, not cleaning professionals. sometimes a customer just needs to be reminded of that.
you are the cleaning professional. you need to educate the customer on the best way to proceed
