How to Safely Pressure Wash Your Roof

Oct 12, 2022 | Roof cleaning

When you live in a home that has a lot of trees, leaves and other debris that can eventually work their way down to the roof, it’s important to be diligent about washing the roof. If you don’t, the debris will harden and decompose, creating a layer that will eventually block the gutter and stop the water from draining properly.

This will lead to water pooling up and going downhill, which can cause further damage outside of the home. In the event that the debris is alive, like vines and weeds, they can start to grow and invade your home. For the purposes of this blog post, I want to focus on the safest way to power wash your roof.

How to Pressure Wash a Roof

Roofs can become dirty and stained from years of weathering. Pressure washing your roof can help remove these buildups, brightening your roof and improving its appearance. While it is possible to pressure wash your roof yourself, it is important to take proper safety precautions to avoid injuries or damage to your roof.

Before you start, check with your local municipality to see if there are any restrictions on pressure washing near your home. You will also need to get permission from your homeowner’s association, if applicable.

To safely pressure wash your roof:

1. Wear protective gear. Pressure washing can be dangerous, so it is important to wear protective gear including goggles, a face mask, and gloves.

2. Use the correct nozzle. A high-pressure nozzle is the best choice for cleaning a roof. Make sure the nozzle is fitted with a safety guard to prevent injuries.

3. Stay clear of the edge. Never stand or walk on the edge of your roof while pressure washing.

4. Keep the pressure low. The pressure of the water should be kept low to avoid damaging your roof.

5. Use a ladder. A ladder is essential for safely reaching the roof. Make sure the ladder is in good condition and is the right height for the job.

6. Inspect the roof. Before starting, inspect the roof for any damage. Do not pressure wash any areas that are damaged or missing shingles.

How a Pressure Washer Can Damage a Roof

A pressure washer can damage a roof by blasting away the protective sealant and stripping away the top layer of the roofing material.

To pressure wash your rood without damaging it:

-Use a low-pressure setting on your pressure washer

-Stay at least 12 inches away from the surface of the roof

-Do not use a pressure washer on a roof that is wet or icy
