Roof Cleaning – The Right Way

Posted by on Dec 1, 2019 in General | Comments Off on Roof Cleaning – The Right Way

As you may already be aware, chemical roof cleaning is a superior alternative to popular roof power washing. There are many benitez pressure washing products and solutions that you can buy these days, all claiming to be superior, and all claiming of which their’s is the safest and most effective, but it’s important to do not forget that these are companies that are just trying to make a buck and may say just about anything to sell their product.

In my considerable practical knowledge, there’s only one way to clean a roof the right way, and that is certainly with a sodium hypochlorite-based solution. Sodium hypochlorite is the active component in bleach and chlorine, and when applied to a roof covering at the right ratios is quite simply the safest, most effective way to decontaminate a roof. It is the recommended method for cleaning roofs by way of ARMA (the Asphalt Roofing Manufacturers Association) and GAF (North America’s largest shingle manufacturer).

ARMA recommends a lot of bleach, water, and TSP (which can be found in paint stores), but be careful with the TSP on painted surfaces because it remove the gloss in high dosages. I have found that the TEASPOONS is helpful but not necessary, as the bleach is the primary soap. In addition , every roof cleaning professional that uses using this method has his or her own “secret” additives that they add to this merge to give it just the right cleaning potency for their climate, although the common denominator is a final liquid solution that is related to 3-4% sodium hypochlorite. So if your common household chlorine bleach is around 6%, you would need to have equal parts bleach plus water to get you down to 3%.

This is by far the reliable and most effective way to clean a roof, but the snatch is that an average one-story ranch house is going to require from about 30 to 60 gallons of total mix. Actually you’d need about 15-30 gallons of typical 6% household bleach. Typically, the pros will have the whole mix within the large poly tank on their truck or trailer, and definitely will use a battery-powered pump to deliver the solution through a long polybraided hose up to the roof surface. They’ll usually have a lighten resistant tip on the end of the hose that smooth disperses a soft spray over the roof surface. They’ll give the solution on the surface to let it do its thing for a few moments before rinsing the surface with water from the garden hose. Hence no power washers or scrubbing should be required (the only exception could be for thick moss accumulations). When you are doing this yourself, you’d also want to keep the whole perimeter of the home rinsed down very well during the application (preferably by a following person) as sodium hypochlorite can have a negative effect on landscape gardening if not properly diluted. Be especially mindful of locations where downspouts empty into grass or other greenery. Often you might have to go over a few spots a second time, but the success should be instant! Rinse the roof and perimeter very well, make it possible for dry, and enjoy your new-looking roof.

You can do this yourself, naturally , but you’d be looking at having to purchase hundreds of dollars truly worth of equipment and chemicals, so why not just hire a professional industry experts non-pressure roof cleaning? Try to find one that utilizes the roof cleaning up chemicals that I just outlined.

If you do decide to go for it your own self, BE CAREFUL. The hazards include, but are not limited to: falling out ladders, slipping on the roof surface (which is made very elusive when solution is applied), getting bleach spray in your face or lungs (wear eye protection and a mask), angling a ladder against a power line, etc . This operate is not for the faint of heart. Harnesses and service systems would be a good idea.

You can expect this type of treatment to keep the top clean anywhere from one to five years before stains will return, with an average of two to three years. I’ve nonetheless to come across any so-called “sealers” that actually work very well. The best choice is just to have the roof re-cleaned by a professional when the algae lines have returned. The zinc strips that some seek to market don’t work that well in my opinion, either. They usually are somewhat effective for the 2-3 feet of roof outside directly below the strip, but what about the rest of the roof? Zinc is also a very expensive material. Just have a pro clean your roof any three to four years and save yourself the hassle.
