Just making a post to direct more attention to the post below "Research prove this?"
I think it's an excellent idea and I'm afraid not many will know to read the post. I will be making a number of videos showing pressure washing shingles ,also cement surface cleaners in use on them, along with No Pressure cleaning them. I am also going to do some on tile roofs, showing how some of the ridge cap cement blows out with pressure washing and not with No Pressure systems. Also, on painted tile, how some paint blows off with pressure. For these to be convincing proof for visiting potential customers, I think it would be best not to use our business name in all of them. That way we could have a page of video tests for roof cleaning methods, that were more convincing than advertising videos? Read the original idea below though, it's not my idea.
Try to get one with the red clay tiles that have been pressure washed and the entire yard is covered red.
I think I have a pic or two around somewhere of that.
