Hello RCIA, Just want to introduce myself and also say thank you to all who have contributed to this forum. The collective knowledge has been a great help thus far. I am an owner/operator of a pressure washing company and I have decided to start offering roof cleaning. I am now in the process of modifying my wash rig to include all of the needed equipment for roofs. I have purchased my compressor and I am making final decisions on pump etc etc... Any suggestions and advice would be greatly appreciated! Kevin, from Peak of Perfection, thank you for your help. Chris, thanks for all of the value and benefit that is offered through this forum. It truly makes a difference when people make a conscious decision to share what they have learned to further the success of others.
