Pressure Washing vs. Soft Washing: Which is Better for Your Roof?

Pressure Washing vs. Soft Washing: Which is Better for Your Roof?

13th September 2023

When it comes to cleaning your roof, there are two primary methods to consider: pressure washing and soft washing. Both techniques have their advantages and disadvantages, so it’s important to understand which one is better suited for your specific needs. In this blog post, we will discuss the differences between pressure washing and soft washing and help you make an informed decision for your roof cleaning needs.

Pressure Washing:

Pressure washing, as the name suggests, involves using high-pressure water to clean the surface of your roof. This method is effective in removing tough stains, dirt, and debris that have built up over time. Pressure washing can be especially useful for roofs with asphalt shingles, as it can blast away moss, algae, and lichen growth.

However, while pressure washing can deliver impressive results, it’s worth noting that it can also cause damage to your roof if not done properly. The high pressure can strip away the protective granules on asphalt shingles, leading to premature deterioration. It can also dislodge tiles or shingles, causing potential leaks and further damage.

Soft Washing:

Soft washing, on the other hand, is a gentler approach to roof cleaning. This method uses a combination of low-pressure water and special cleaning solutions to remove dirt, stains, and organic growth. Soft washing is particularly effective for roofs with delicate materials such as slate, tile, or cedar shake, as it minimises the risk of damage.

The cleaning solution used in soft washing is typically biodegradable and environmentally friendly, making it a safer option for both your roof and the surrounding environment. The low-pressure application also ensures that water doesn’t penetrate through the roof and cause potential leaks or water damage.

Which Method is Better for Your Roof?

The choice between pressure washing and soft washing ultimately depends on the type of roof you have and the specific cleaning needs. Here are some factors to consider when making your decision:

  1. Roof Material: Different roofing materials require different cleaning methods. Pressure washing may be suitable for roofs with asphalt shingles that can withstand high-pressure water. Soft washing, on the other hand, is better suited for delicate materials like slate, tile, or cedar shake.
  2. Condition of the Roof: If your roof is heavily stained, covered in moss or algae, or has significant organic growth, pressure washing may be necessary to effectively remove these stubborn contaminants. Soft washing is generally sufficient for regular maintenance and light cleaning.
  3. Potential Damage: While pressure washing can deliver quick and noticeable results, it also carries a higher risk of causing damage to your roof if not done properly. Soft washing, with its gentler approach, minimises the risk of damage and is a safer option for roofs with delicate materials.
  4. Environmental Impact: If you prioritise eco-friendliness, soft washing is the way to go. The biodegradable cleaning solutions used in soft washing are less harmful to the environment compared to the chemicals and detergents used in pressure washing.
