7 Alternatives to Roof Pressure Washing: What They Are and Their Benefits 

Cleaning your roof is a lot of work. Especially if you live in an area with heavy rain and strong winds, it can be very difficult to keep your roof clean. That’s why many people choose roof pressure washing as the quickest way to get their roofs looking clean again. But before you start spraying, there are some things you should know about this method and how it can damage your roof. Today we’ll cover what pressure washing does, the risks involved with this type of cleaning, and finally offer some alternatives that might work better for different types of roofs or living situations. Ready? Let’s go! 

Pressure washing is a type of cleaning that uses high-pressure water to remove dirt, grime, and other build-up from surfaces. This method is often used on driveways, sidewalks, and even roofs. While it can be an effective way to clean these areas, it’s important to understand the risks involved in pressure washing before you start. 

For one, pressure washing can damage your roofing materials. The high-pressure water can strip away the protective coating on asphalt shingles, making them more susceptible to wind and weather damage. Pressure washing can also cause leaks by loosening or breaking seals around flashing or vents. In some cases, the force of the water can even break tiles or shingles, resulting in costly repairs. 

In addition to damage, pressure washing can also be dangerous. The high-pressure water can injure you or anyone nearby if it hits them directly. And if you’re not careful, the water can also damage your property, including windows, doors, and siding. 

So what are some alternatives to pressure washing your roof? Here are 7 options to consider: 

1. Handwashing: This is the most low-tech option on our list, but it’s also the safest. You can rent a power washer from most home improvement stores, but we recommend using a pump sprayer with a garden hose for smaller roofs. Simply wet down your roof with the hose, apply a generous amount of soap, and scrub with a soft brush. Rinse thoroughly and repeat as necessary.
2. Roof Cleaning Products: There are many different products on the market that are designed specifically for cleaning roofs. These products usually come in a concentrate that you mix with water, and they can be applied with a pump sprayer or garden hose. Follow the instructions on the packaging and be sure to rinse thoroughly afterwards.
3. Bleach: Bleach is a powerful cleaning agent that can kill mold, mildew, and algae. However, it’s also very corrosive, so it should only be used as a last resort. If you do decide to use bleach, be sure to dilute it with water and rinse your roof.
4. Vinegar: Vinegar is a mild acid that can kill mold, mildew, and algae. It’s also much less corrosive than bleach, so it’s a safer option for cleaning your roof. Simply mix equal parts vinegar and water, apply it to your roof with a pump sprayer or garden hose, and scrub with a soft brush. 
5. Baking Soda: Baking soda is a gentle abrasive that can be used to clean mold, mildew, and algae off of your roof. Simply mix equal parts baking soda and water, apply it to the affected areas, and scrub with a soft brush. 
6. Oxygenated Bleach: Oxygenated bleach is a safe and effective alternative to chlorine bleach. It can be used to clean mold, mildew, and algae off of your roof, and it won’t damage your roofing materials. Simply mix equal parts oxygenated bleach and water, apply it to the affected areas.

   

7. Pressure Washing (Carefully!): If you absolutely must pressure wash your roof, there are a few things you can do to minimize the risk of damage. First, use the lowest pressure setting that will still get the job done. Second, hold the nozzle at least 12 inches away from your roof and keep it moving to avoid concentrated areas of pressure. Finally, rinse your roof thoroughly afterwards to remove any soap residue.

If you’re not comfortable cleaning your roof yourself, there are many professional roof cleaners who would be happy to do it for you. Be sure to ask around for recommendations, and get multiple bids before making a decision.
