Best Pressure Washer for Roof Cleaning Reviews Buying Guide:

When I was researching these products, I realized that it’s straightforward to make a mistake and buy the wrong item. Yes, you may purchase a model under your budget, but the pressure might be too low to handle your cleaning. That’s why I decided to offer this buying guide to help you make the ideal choice.

Type of the pressure washer

Pressure washers are of two types; the gas models and the electric models. The electric models are quite small, quiet, and portable, but cannot handle heavy-duty cleaning. On the other hand, the gas-powered models are quite powerful but noisy and expensive. If you need to clean your home roofs and the power supply is reliable, then the electric power washer is ideal for you. However, if you’re cleaning your cabin roof or a commercial roof, then you will need a generator that is powerful enough to clean the mess.

Machine Rating

The pressure rating and the water flow rating matters a lot when it comes to roof cleaning. The pressure is needed to blast out the dirt, grime, and molds from your roof, and the water flow is required to force all these out of your roof. You need to pick a model with above 1500 psi and 1.5 GPM water flow. That should be enough to handle any time of roof cleaning.

Detergent tank

Detergent is a must if you want to deal with the stubborn dirt, grease, and grime on your roof. I recommend you select that comes with either an onboard or an attaching detergent tank where you can add your cleaning agent. The bigger, the better.

Hose length

Some roof is quite tall and hard to reach, and in some circumstances, you will need to climb to the roof for the cleaning. You need to simplify your hassle by picking a model that comes with the most extended pressure hose. It should allow you to reach the rooftop with ease.


Another thing to consider is the machine noise. Pick a model that runs quietly without disturbing the neighbor or your home residence.


You should also pick a model that will be easy to carry and store. A model you can maneuver around the house as you do the cleaning.

Best Pressure Washer for Roof Cleaning (FAQs)

Q: What cleaning solution should I use when cleaning my roof?

A: Different brands have different recommendations. All you need to know is, you should use detergents designed for use with pressure washers. Never use other cleaners like bleach as they might damage the pump or shorten your machine life.

Q: How do I unclog a clogged nozzle?

A: First of all, you’ve to turn off the machine, disconnect the spray gun, and examine the nozzle. If clogged, use a thin needle or wire to poke any obstruction out. After that, run water through the hose nozzle to remove any remaining debris. Lastly, connect it to your pressure washer and try again.


Once you have the right pressure washing machine for your roof, the task should be simple and straightforward. I believe I have served you with enough information to guide you in buying an ideal pressure washer for cleaning your roofs. Always ensure that the model you pick meets all your requirements before checking it out.
