The pump on your Skid will flat go away, unless you rinse it out as soon as you are done cleaning the roof, and even if you do, that pump is not one of the most reliable roof cleaning pumps! Welcome to the roof cleaning institute! Many of our members are over here, on the Facebook Group https://www.facebook.com/groups/174087666708523/ Please post this over there, for better response.

Safety is important

Chris will never steer you wrong when it comes to roof cleaning. He had these pumps, and they dumped on him when he needed warranty help. A lot of people in the industry are aware of the problems with these roof cleaning pumps, mostly because of his advocacy for something better and the other people who have had issues with them. I'm sorry people were bashing you on facebook. Every Tom, Dick, and Harry has access to the internet now, and that is the result. Before smart phones, not everyone could get online, so things were much better then. Although you also had the results of many people being anonymous online. Anyway, back to the pumps. It's unfortunate they still tell people it's made for roof cleaning. Just take Chris's advice and keep it clean. At the same time, prepare for some upgrades/changes in your equipment to make life easier.

Your UDOR Pump is NOT "specially designed" for roof cleaning, I am sorry to say. I have one in my shed that quit on me, years ago. You are welcome to drive here to see it. The UDOR is a pump for pest control, tree and agricultural spraying, etc. The crooks at UDOR, who refused to honor my warranty on their UDOR Zeta Pump when it broke, got the bright idea to market the pump to our roof cleaning industry. All you have to do is look at what materials are used in it, to know there are much better materials to make a pump from. Nevertheless, it will last awhile, as long as you rinse it out RIGHT AWAY. The Diaphragms last awhile, Doubt you will need to worry about them. Glad you got new fittings made out of Polyproplyne ! Your old ones were NYLON, a big No NO for roof cleaning chemical use. Next, you either need a new tank, or move the bypass hose to the TOP of the tank. That Skid you bought looks like it was aimed at the Pest Control People. They seldom if ever fill their tanks all the way up, so a pump bypass on the side of the tank is no big deal.

Welcome Thomas. Funny, you have the same name of a roofing company we handle roof cleaning referrals for here in Jacksonville, Florida. We have a few roofers that we do work with or handle their roof cleaning referrals for.

Thanks for sharing important points. I have found a nice article on roof cleaning and regular inspection. Read here https://crownroofing.ca/blog/what-is-the-importance-of-regular-roof-maintenance/

Sometimes, we can run into rust on shingle roofs. I always used an acid wash to remove it that I made up myself. These pictures are from Craig Harrison of F9 BARC, who make an excellent already mixed acid based cleaner for exactly this purpose

There should be a D.I.Y on this site for a soft wash system... I think when i get my air setup complete.. i am going to make a step by step instruction for a basic roof cleaning system 100 gallon with pictures parts, part numbers etc. But it should be kept confidential to paid members of this forum. let me know what you think.

David; There are several ways to start out. 12v electric pump which will allow you to shoot 25' up to 40' depending on your hose size and nozzle. I used that system for over 2 years until it got where it would only shoot 12-15'. Chemicals we use take their toll on equipment. I then upgraded to a air system where I use a BIG gas powered air compressor and a 1" aodd pump with 3/4" hose, a special nozzle, and 1/2" air hose. This allows me to shoot over 70'. Nice to have the extra power/capacity when you need it. Safety is always a major concern. I built my system so I would never have to get on a roof. I spray all from the gutter line or ground.I am 67 and have had both knees replaced and don't need to fall off anything. Just read on here, start out slow with some help and learn as you go. If you got any questions, call either Chris, or myself. Welcome aboard. Gary
