Soft washing which is the application of chemical cleaning agents with low pressure to attack the organic bacteria's roots leaving behind a brighter and longer lasting clean. Last longer and does less damage than conventional high pressure cleaning. Below is a prime example of what the soft washing method is capable of.
The other option we have to cleaning a roof is high pressure cleaning which can not be used when cleaning mold off shingle tiles as it will tear away the roofs sensitive granuals, cutting down on the roofs life expectancy and protentional to protect from water leakage. Many so called pressure cleaning professionals still believe the best way to clean a roof if my hitting it with high power and this will wash away any black stained organic streaks. False, they only remove the organic stains from the visible eye. When we take a closer look into the tiles porous material we find left over bacteria that was not fully eliminated. High pressure can not only damage the tiles longevity by scaring it but it can also open up seals made by the roofers to protect from water leaking into the home. The only upside to this method of cleaning is a cheaper cost due to its use of only water to get the job done. Although in the long run it will cost you more as a homeowner not to mention the headaches of getting roofing contractors to inspect the roof for where the leak is coming from. Therefore completely nullifying the lower cost in the short term. As more damage is done rather than help.
The extra added cost to soft washing is from the material placed on the roof to kill the bacteria's roots when compared to high pressure cleaning we often see a price differeance of about $100-$150 dollars.
Lets take a closer look into the pros and cons of soft washing versus high pressure washing
Pros of Soft Washing
Last longer than conventional high water pressure cleaning (Approximately 2 years)
Much safer to use on a roofs tiles both asphalt shingle and barrel tile shingle roofs.
Kills the mold systematically at the root
Exposes more of the roofs natural color to the surface
Zero chance of roof leakage
Uses less water (Approximately one tenth of the water consumed)
No heavy equiptment is brought up on your roof and that mean high safety for you as a homeowner and the person doing the cleaning
Now lets go over the pros of high pressure cleaning a roof
Pros of High Pressure Washing
Lower cost on average
Seems like an obvious choice to make right, but lets keep weighing out the cons next
Cons of Soft Washing
Usually a higher cost due to the amount of material applied to the roof and time in protection plant life
Cons of High Pressure Washing
High chance of roof damage (cutting the roofs lifespan)
High chance of roof water leakage
Will not clean down the root (the bacterial microbes will still be rooted deep in the roof tiles and will appear to the human eye in less than a year)
Dangerous to the operator and homeowner.
In this head to head battle we have to give the Soft Washing Method the Gold medal for achieving the best possible clean with safety and quality in mind.
It is best to keep the high pressure cleaning on the ground for driveway, patios and walkways to reach deep into the surfaces pores, but we still want to apply a pretreatment as a precaution and to loosen up the mold and mildew.
We want to show you a few example of the damage high pressure washing a roof can do below.
We cant just leave you with the damage high pressure can do without showing you the beauty the Soft Washing Method can do to tiles roofs too.
In conclusion The Soft Washing Method is better than conventional high pressure washing for a variety of reasons such as safety, longevity and quality.
