How long does it take to clean a roof?

Cleaning a roof is a challenging task and can be a very time-consuming process. It also depends if you are cleaning the roof yourself or hiring a professional roof cleaning company. 

Depending on the size of the roof and the amount of debris that needs to be cleaned off, it can take anywhere from two to six hours for a cleaning company to clean a home roof thoroughly.

What affects the time it takes to clean a roof?

Several factors will affect how long a roof cleaning takes. If moss has accumulated on the roof tile or shingle, it will likely take longer because of the extra effort needed to remove it. 

If pressure washing is required, it could take up to two days since there are usually two faces of the roof that need to be cleaned and dried. 

In any case, depending on the type of material used for your roofing and how much dirt has built up over time, you should expect that the overall roof cleaning process will take around two to six hours to complete. 

The length of time it takes to clean a roof will depend on the size, the type of roof, the condition, and the method used to clean it. 

Here are some rough estimates for how long it might take to clean a roof:

  • For a small roof (e.g., a single-story home) with no major issues, it might take a couple of hours to clean.
  • For a larger roof (e.g., a two-story home or a commercial building) with no major issues might take a whole day to clean.
  • For a roof with significant stains, algae, or other issues might take multiple days to clean.


In general, it’s a good idea to allow extra time when cleaning a roof, as unforeseen issues may arise or areas that require more attention than expected.

Is it worth getting my roof cleaned?

Getting your roof cleaned can be a great investment for your home. It will help to prevent any damage to your roof caused by dirt, debris, and other build-ups that can occur over time. 

Additionally, having a clean roof will help improve your home’s overall aesthetic and make it look more presentable. 

Furthermore, if you live in an area prone to extreme weather conditions such as heavy rain or hail, getting your roof cleaned regularly can help protect it from any potential damage these elements may cause. 

Getting your roof cleaned is worth it if you want to keep your home looking good and safe from possible harm.

What Does Roof Cleaning Involve?

Roof cleaning is crucial to home maintenance, ensuring that your roof remains in good condition and free from moss and algae. 

It typically involves using a pressure washer to remove dirt and debris from the surface of your roof. Depending on the type of roof you have, different cleaning methods may be used. 

For example, roofs made from tile or shingle may require more gentle cleaning methods, such as soft washing. On the other hand, metal roofs can usually withstand stronger pressure washers without damage. 

Regardless of the method used for cleaning a roof, any moss or algae will need to be removed with a brush before using any cleaning solutions or pressure washers.  

Several methods can be used to clean a roof, including

  1. Pressure washing: This method involves using a high-pressure stream of water to remove dirt and debris from the roof.
  2. Chemical cleaning: This method involves applying a cleaning solution to the roof and allowing it to sit for some time before rinsing it off. The cleaning solution helps to loosen dirt and stains, making it easier to remove them.
  3. Soft washing: This method is similar to pressure washing, but it uses a lower pressure setting and a specialised cleaning solution to gently remove dirt and stains from the roof.
  4. Hand cleaning: This method involves manually scrubbing the roof with a brush or sponge to remove dirt and stains. This method is typically used for roofs too steep or fragile to be cleaned using other methods.

Before cleaning a roof, it’s important to identify the type of roof and the materials used, as different roofs may require different cleaning methods. 

It’s also important to use caution when cleaning a roof, as it can be a hazardous task due to the height and slope of the roof. 

When is the best time to clean a roof?

When cleaning a roof, the best time is usually during the spring or fall when temperatures are mild, and there is less chance of rain.

We recommend inspecting your roof twice a year in order to prevent any serious damage from occurring. If you find moss growth on your roof, it should be removed with a stiff brush or pressure washer before being treated with an anti-moss treatment solution. 

Cleaning your roof regularly will help keep it looking good and also help maintain the house’s value over time.

How long does roof cleaning last?

Roof cleaning can last a long time, depending on the roof and the environmental conditions it is exposed to. 

Generally speaking, roof cleaning should be done at least every two years to keep the roof looking its best and protect it from damage. 

However, this timeline may need to be adjusted if the roof is exposed to harsh weather conditions or has more debris than usual. Additionally, some roofs may require more frequent cleaning due to certain materials or coatings that have been applied. 

Proper maintenance is vital to keeping a roof clean and in good condition, so regular inspections are recommended to determine the best cleaning schedule for your specific needs.
