Shingle Roof Cleaning. Do Not Pressure Wash!

This is a video of a roof we cleaned recently. Watch how gentle the cleaning process is. It is the process that the roofing manufacturers say to use. They also say "Do Not Pressure Wash" You can watch the whole 10 minute video, or the first 10 seconds and then jump ahead to the last 10 seconds. YOU WILL BE IMPRESSED! http://www.youtube.com/watch?v=WPCtVUu3Si0&feature=plcp This is a recent Rotonda West job - http://www.youtube.com/watch?v=Ism_iEw36rg
