A professional roof cleaner in the NJ area may have a truck that looks something like this. Most professionals have truck mounted equipment. It’s not to say someone with a walkable machine can’t do a good job. God knows how many years I’ve humped a machine in and out of my Jeep when I was a kid starting out. That’s right, a Jeep! We’ve built quite a reputation over the years and we needed to save time and give the same quality service. Truck mounting our equipment was the best way to do this. What you’re seeing in this picture is only half of the vehicle (the roof cleaning half). Since our roofing detergent is so biodegradable, we need this equipment to concoct our mix then rotate it in the tank. We cannot make large quantities of dtergent and store. It has no shelf life. Every roof gets it own “made to order” solution that can be tweeked according to the level of growth on the roof. It may look overwhelming, but it’s quite simple after a brief training. We are able to handle a high influx of calls with our professional roof cleaning unit and still give the high level of service that people expect.
