Three Reasons Why Pressure Washing Is The Better Option For Blasting Moss And Algae

When you are faced with a lot of moss and algae stuck to the roof of your house, your outdoor walkways, and stone patio, you are probably thinking you should hit these areas with an herbicide. That seems reasonable, but then there is always the question of the harm you will be doing to the environment and the potential leaks in your roof. Another way to deal with the moss and algae is through pressure washing. Here is why pressure washing is the better option for blasting away moss and algae.

Pressure Washing Is Environmentally Friendly

Herbicides are toxic, regardless of their use, and they could hurt wildlife, your family, and lots of other living things you do not want to poison. These plant killers will destroy the moss and the algae, but they will also sink into the ground and into the water table. If you draw water from a well, this is especially dangerous to your household.

If you use city water, the herbicides still end up in the water supply and cannot be fully removed. The pressure washing uses only hot or cold water and extreme pressure to remove these problem plants. It leaves everyone and everything in the environment healthier for it.

Extreme Pressure Removes These Plants down to the Root

When moss and algae are blasted with 1,500 psi (pounds of pressure per square inch), it is the equivalent of having someone lift your hair from your head and carry you several yards into the air by your hair. Eventually, your hair would pull free and you would drop to the ground.

That is what a commercial pressure washer can do to the moss and algae. The pressure washer hits these plants with so much pressure that it tears them out by the roots, leaving nothing behind to regrow. That means you will not have to repeat this process again for some time, unlike the herbicide which would have to be reapplied every few weeks.

Pressure Washing Is Quick and Easy

Using herbicides is neither quick nor easy. You have to mix the chemicals just right, put them inside a tank, close the tank tightly, and then walk around, carefully spraying the moss and algae such that you do not spray anything else green and growing. Pressure washing only requires a faucet attachment to feed water into the tank of the machine, and you can blast the moss and algae from far away, too. It takes just a few minutes to complete the pressure washing, versus the hour or more of herbicide treatments.
