The difference between power and pressure washing
If you are searching for techniques to clean your roof, there is a good chance that you came across the terms pressure and power, used with washing. Pressure and power refer to the act of forcing a stream of water through a very small nozzle significantly increasing the pressure of the water from faucet to surface. This is done via a generator that could be either gas or electric powered.
Your home improvement store could sell you a unit that delivers pressures from 2,000 to 4000+ psi. You could hire someone to do it but then you wouldn’t know what they would be bringing. To answer the question, pressure and power mean the same thing when looking at water washing. Now that you know what power and pressure mean, forget that you ever searched for roof cleaning with pressure or power washing. Keep the pressure washer for stone and concrete or any other surface that can actually stand high pressures.
You shouldn’t use either
Instead, you need to use more than just water. Water alone won’t clean your roof, even if it is high-pressured. It won’t clean the mold off. It will clean the mold off and pieces of your roof. Your asphalt shingles are actually softer than you think and weren’t made to withstand the high-pressures experienced from a power washer. Soft washing uses a mix of detergents, water, and bleach to clean out all of mold and stains on your roof. A professional will have the proper mix of chemicals and will then use a low-pressure system to rinse the debris off. When you need to remove the toxic algae, pollen, and mold growths slowly degrading your roof, hire a trained professional experienced in soft washing. They can bring the detergent and the right type of hose wand to properly and carefully clean your roof without damaging it.
