We have had one of the top ranked websites for Roof Cleaning for many years. As a result, I get about 3 people a week, sometimes more, wanting to learn about cleaning roofs. Many ask me "Chris, why don't you have a video showing the roof cleaning process to your customers and us guys trying to learn how to do it. Well, we DID have one of these videos, it turned out to be a BIG Mistake, so we trashed it. Customers were saying "What do you mean 1200.00 just to spray some chit on my roof, that's all you are doing"
