How to Clean a Roof


how to clean a roofAs a proud homeowner, you want your home to sparkle from top to bottom, not just inside but on the outside as well. As a result, you may be wondering if it’s necessary to clean your roof.  

Cleaning the roof is a big job and requires a lot of time and effort. Depending on how you handle the job, there is some risk. You also have options when it comes to cleaning the roof. In this article, we cover a few items you should consider before attempting to clean your roof.  

Benefits of Cleaning Your Roof  

Cleaning a roof can extend its life span. It can help protect the shingles and other roofing materials. In addition, cleaning your roof will eliminate any algae or moss that may be growing on it.  

Algae is composed of diverse aquatic organisms that produce oxygen through photosynthesis. This organism looks like mold. It’s primarily found in areas with warm, humid summers. Although algae is unlikely to damage the roof shingles permanently, the organism can negatively affect the roof performance, which can lead to damage to your home.  

Moss is a non-vascular flowerless plant that absorbs water through its leaves. Unlike algae, moss can cause much more damage. If moss isn’t managed, it can spread and degrade the structure of the roof, leading to high repair costs.  

Disadvantages of Cleaning Your Roof  

As mentioned before, cleaning the roof takes effort and preparation. Not only does the roof need to be prepared, but nearby plants and vegetation also do.  

Most roof cleaning products contain bleach, and bleach is harmful to plants. So, before starting the roof cleaning process, make sure to cover any nearby plants. Water them before the plants are covered. 

Also, keep in mind that working on a roof can be dangerous. Falls and falling materials are possible when working from a roof. Make sure to have a spotter as you work if you need to climb on the roof. If possible and for safety, use a professional roofing company for the cleaning. 

Best Spray-on Roof Cleaner 

There are many spray roof cleaners available over the counter. A DIY one will also work just fine. Chlorine bleach combined with water is enough to kill both algae and moss. Let the bleach solution sit on the roof for 20 minutes. Then rinse the solution away with clean water.  

As a finishing touch, use a leaf blower to remove any fallen leaves, moss, or other materials.  

When cleaning a roof, do not use a pressure washer. A pressure washer can damage the asphalt shingles.
