I am just getting into the business of non pressure roof cleaning and am curious as to what setup would be recommended for someone in my shoes. I am intrigued by the air compressor ran systems. I am certainly on a budget being a full time student with two kids, however I want to get something that will perform as needed without killing my pocket. I am looking for specifics such as type of pump, hose I should run, spray gun, reel and anything else I should need. I have already purchased the metal framed ibc totes as they hold a lot of liquid and are extremely affordable. As I mentioned before I need affordable but am willing to spend a little more on a decent pump as I know it will pay off in the long run. I am extremely new to the field and was introduced to it by a friend who is also new to it, however, I find it a good investment as there is no one in my area that offers a non pressure roof cleaning. I am looking for a "what I wish I had bought when I first started out" scenario with a budget in mind twist to it. I appreciate any response from you guys. As soon as I can afford to get a membership on here, you can bet it will happen as I have many more questions but respect that good advice comes with a price.
