Oh Chad & Josh This group is right in my back door, it is all a bunch of scamming BS and hype to coerce people to use them. I have a folder 2" thick on them. Deception is the name of the game. He cleans barrel tile roofs for .09 cents a ft. then sells some foamy BS to prevent algae growth. The funny thing is the HO never questions the validity of their claims they make. Just that they get a warranty and come back to spray it on again every year which is the fine print, they charge to come back and spray, so what is the point of the warranty.
