The Roofster is an exceptional chlorine pump skid system available only from Sun Brite Supply. We drive an extraordinary John Blue Chlorine Pump with a small gas engine and mount it on an aircraft-aluminum skid frame. This is one of the few gas-powered systems available, and the only one that is warranted for a full year by the manufacturer!
The pump is constructed with polypropylene and chemical-resistant stainless steel and is guaranteed to stand up to pure 10% chlorine for One Full Year by the manufacturer. The pump skid includes a gear-reduction to run the pump at a long-lasting 650 RPM, so the pump has exceptional durability. The factory rates this pump at 4.3 GPM, but our test model delivered a consistent 5 GPM. The skid unit includes a regulator that limits the overall delivery force to just 150 PSI for "no pressure" cleaning.
This Bleach Pump was run-tested for months without any problems whatsoever.
Using strong bleach is a favorite way to clean mold and algae off roofs and other surfaces too steep to walk on. Spraying strong sodium hypochlorite kills the mold fast. Problem is, this is such a corrosive chemical that it also attacks the equipment used to spray it. This is the most economical answer we could develop to deal with corrosive chemicals. We achieved streams of 40 - 50 feet at approximately 5 GPM during our testing process.
You can order the pump skid alone, or you can order a complete system according to your needs. See all of the accessories below and build the system that is right for you.
"All the people at Sunbrite Supply that I dealt with were very prompt, helpful, friendly and patient. Just getting into the pressure cleaning biz I knew very little. The staff at Sunbrite Supply were very instrumental in getting me going with the right equipment and procedure to do a professional job. The pricing is excellent and I got my equipment quickly. I highly recommend them." Peter B, Pennsylvania
1. Bleach (sodium hypochlorite) must be fresh! Bleach degenerates quickly if exposed to sunlight or heat. If you buy bleach from a grocery store, go to one that moves a lot of product (such as a Wal Mart). If you buy industrial bleach, do not buy more than you can use in a few weeks and protect the chemical from sunlight and heat.
2. Bleach purchased in a grocery store is rated at 5.75%. Industrial bleach is usually around 12.5% in concentration. Either can be used for roof cleaning, because you want your final concentration to be between 4% and 6%.
3. Bleach is commonly used to clean moldy roofs at around a 6% concentration level PLUS soap. You need soap to give the product enough "cling" to stay on the roof long enough to kill the mold. Power House is an excellent soap for this purpose because of the high-sudsing surfactants in it.
4. If you use Green Wash (from Soft Wash Systems) as your soap, most contractors find that they can drop the concentration of bleach down to the 4% range - saving them money.
5. Temperature has a major impact on how well your cleaning mix will work. if the temps are between 60° and 90°, you can count on quick action. If the temperature is below 50°, you may find that you need to let your cleaning mix dwell 2-3 times as long to see any action. The colder it gets, the less they work.
6. Most contractors find that they need a hose length of 200' to 300' to handle most jobs. Avoid problems by using a full length of hose rather than coupling smaller hoses together.
7. Hoses may be bleach-rated - or not. Most hoses that are bleach-rated are made from materials that won't react to bleach and they are ended with stainless fittings. They last a long time. Some contractors prefer to save money by using simple poly-braid hose with the clear understanding that they might have to replace that hose frequently.
8. Many contractors prefer large diameter hoses that minimize internal resistance and maximize throw distance. In our tests, there was little difference in the results when comparing a 3/8" bleach-rated hose and a 1/2" poly-braid hose in the overall throw distance achieved.
9. The pick-up hose between your pump and your tank should be crush-proof so that it cannot collapse and starve your pump. We suggest Spiraflex hose.
10. Although the average roof is around 3000 square feet, and logic tells you that 20 gallons of material will cover that much area, most contractors end up using 3 times that amount of mixed cleaning solution per job. Therefore, a 125-gallon tank will only carry enough pre-diluted mix for two roof cleaning jobs. If you are setting up to do more jobs in a day than that, carry your bleach undiluted in one tank and mix it as needed into a second (or dilution) tank. NOTE: You are limited by law to no more than 1000 pounds of strong chemicals like bleach. That breaks down to around 125 gallons of material, which is why we suggest a 125-gallon tank.
Bonus: Your roof cleaning system can be used to clean other surfaces, such as houses. Simply adjust your cleaning mix down to a 1% to 1.5% bleach concentration, and you can use this system in place of using a pressure washer.
This is the most durable chlorine pump on the market today - and the only one warranted to last!
