The first thing you’ll need to start soft washing is a functional soft wash system. A soft wash system, at its most basic, comprises a tank for holding the cleaning solutions, a pump and hoses for moving chemicals, a trigger gun for controlling flow, and a nozzle for directing the spray. You can find a lot more information on the best products to use, suggested method of application and how best to undertake treatment on various surfaces by visiting our information sheets
Chemical-based cleaners often use chemicals like ammonia, copper sulfate, and trisodium phosphate. They can be harsh, but they’re extremely effective at removing the stains as well as the molds, algae, and mosses that cause them. Simply diluting them to the manufacturer’s recommended mixture does reduce some of the risk, so read the directions carefully. Coverage The best technique for cleaning your roof is to scrape off any moss or debris using a roof scraper or wire brush. Once the surface is clear, a softwashing chemical should be applied to kill any remaining moss or algae. Softwashing is a low-pressure washing method that uses a chemical solution to clean and kill moss and other organic matter. One of the best selling softwash roof treatment products on the market is Soft Wash Pro 50. This product is specially formulated to kill moss and algae on roofs and other surfaces. Yes, there are machines designed specifically for soft washing, which are simply referred to as soft wash systems. A soft wash system, as the name implies, employs a gentler approach, relying on surfactants to remove stains and debris while incorporating low-pressure pumps to reduce the risk of damage. Special discount pricing is available for roof cleaners, painters and contractors purchasing ½ pallets and full pallets of Roof Wash. TestimonialsWater your plants heavily before, during, and after using your cleaner. Diluting the concentration of chemicals is the best way to lessen the risk of damage. Alternative cleaning methods, such as pressure washing, only clean the surface of your roof and do not effectively remove moss, mold, mildew, or algae. There’s always the possibility that they’ll return. Next, repair any loose shingles or flashings, and clean the gutters and downspouts so they can drain freely. This is a rare alternative cleaner. It is a very potent chemical and should only be used by professionals.
There are different kinds of roof treatments out there, and it is okay to worry about what they would do to your roof in the long run. You definitely spent thousands of dollars on your roof, which is why it is a must to stay alert about how your roof cleaners clean it. Whatever the roof cleaning strategies used, they better be good. Note: NEVER load Bio-Wash Roof Cleaner into the pressure washer soap reservoir for application under pressure. The process of soft washing a roof inclusive of the preparations and assembly is quite a task and requires quite an amount of effort and labor. You may not be able to remove all of it, but it is best to remove as much large debris and moss as possible to ensure that the cleaners cover the entire roof and penetrate well.
Prevent regrowth
Cleaning your roof isn’t all that entertaining or fun, so it should be made as painless as possible. Finding a user-friendly product can make all the difference.
You can apply this concentrate at full strength or dilute it for lighter stains. The application requires spraying the roof surface and letting it break down the stain. Once the stain disappears, rinse the roof thoroughly. If the stain remains after the roof dries, another application of Star Brite should remove the rest of the mildew. Most homeowners do not have the capability of cleaning their roof the way a contractor would so most choose method number 2 and let Mother Nature help out. Nothing will ever get a roof as clean as when it is physically washed down with a pressure washer, but this method will get the roof pretty darn close, let's say 85-90% cleaner. To do this, apply the solution to the roof and let it dry, then apply one more coat and leave the roof for Mother Nature to wash. A repeat application may be necessary after a number of rainstorms if the roof isn't as clean as you would like it but you can clearly see the roof get cleaner and cleaner after every storm, it will continue to clean itself for months and months after the application.
