Roof pressure washing and cleaning is a method of removing algae, fungus and other debris from the floor of the roof. Over a period of time, rain and other natural causes lead to the accumulation of these materials (example lichens) on the roof, which may cause its lifespan to decrease by quite a few years.
How to Pressure Wash a Roof?
Pressure washing your roof is a process in itself and though there aren’t many steps which one must follow, they’re both quite important. Keep in mind that missing out either of the steps may render the whole process unnecessary or not fruitful. Let us look at both the steps which one must follow, in order to pressure wash a roof.
Start off the whole process by applying a good quality detergent
A good quality biodegradable pressure washing safe detergent will surely do the trick. By applying this detergent, you make sure that all the moss, algae, lichen and fungus which lie on the roof can easily be cleaned and doesn’t require any excess granules with it. Know and understand that no amount of excess pressure is to be used, because then, the shingles on your roof might end up getting themselves damaged.
When you apply a detergent right in the beginning, with the help of foamer or soap shooter, you make an attempt to loosen all the unwanted growth which has made the shingles on your roof their home, so that less pressure is needed to spray them away. Work in parts. That is, apply a detergent on one part of the roof and then spray clean it, and then proceed to another part of the roof and so on. This will ensure that the roof isn’t slippery so that you are safe from accidents.
Make use of low pressure in order to spray it clean:
Understand that a pressure washer has the power to damage your roof, which is why it is of utmost importance to select a proper spray that will do its work and not damage your roof in the process. Start off the cleaning process by using a medium pressure spray pattern and then make adjustments accordingly.

Make sure to aim the pressure wash towards the downside on the roof and place the tip of the wand at a distance of at least a foot away from the surface of the roof when you start.
