Today I am going to share with you the differences between soft wash roof cleaning, which can also be called chemical roof cleaning, and the other form of roof cleaning, which is pressure washing the roof.
However, before we get into that, I am going to explain the reason behind why roof cleaning is an essential service that you should have done every 4 to 5 years for your property.
Why do I need roof cleaning?
In areas with high humidity and temperatures especially in Florida, there is a specific type of Cyanobacteria that is responsible for creating black stains in streaks on shingle and tile roofs, and this bacteria is called Gloeocapsa Magma.
If the bacteria is left untreated it will only become more noticeable and worsening year to year, Breaking down the shingle granules and weakening the tile strength of your roof – decreasing your roof’s ability to reflect ultra-violet rays of light, overall shortening the life of your roof.
The build-up of Gloeocaspa magma on your property leads to premature roof replacements, lower property value, insurance company policy violations, and increased utility cost due to the black stains drawing in more heat, making your A/C work overtime to cool down your home.
What is soft wash roof cleaning?
Before the explosion of the word “soft washing,” the primary way of cleaning any roof was the use of high pressure.
That was all in so many insurance companies would have an outstanding amount of claims for people having roof leaks and various other roofing problems that needed expensive repairs.
Now, the most current solution today? Is called soft washing, which is applying sodium hypochlorite diluted with water until you reach anywhere from 20% to 40% mix, so you know if you ever hear the term roof cleaning chemicals, that is what’s of use.
Can Roof Cleaning Chemical Harm Anything?
Where the expertise comes in, the landscape next to your property, because if any of the roof washing chemicals is too potent, it’ll be too strong for certain types of plants, and if the plants are not being carefully monitored, watered down, and then covered up, you’ll end up with a bunch of dead plants.
What you also should take note of is knowing exactly how much roof cleaning solution you must use, if you use too much chemical on a roof that does not have a lot of bacteria, you will be damaging the limestone granules.
However, if you are using too little, the bacteria will come right back faster than it took to clean.
Is roof pressure washing safe?
Quick answer: No. Don’t let anyone use high pressure on your roof. Especially if you see the roof cleaning company you called pull these out:
Using high demand on your roof has so many more negatives than positives, and that’s if you count a “kinda” clean roof as a positive.
Pressure washing a roof will be the direct result in loss of shingle granules, which are there to protect the asphalt in the shingle from the UV rays of the sun.
Missing granules is the sign that it is time to replace your roof, along with a notice that your warranty is gone after the high-pressure roof cleaning service has done its damage.
If you’re not choosing Kleen Springs as you roof cleaning service company:
please make sure always to use a reputable contractor who adheres to the removal techniques of the Asphalt Roofing Manufacturers Association.
Both groups advise against power washing roofs because it’s potentially damaging.
