What is Softwashing: The New Roof Cleaning Method


If you’ve noticed dark streaks or algae stains on your roof, there’s no need to worry. The softwashing technique for roof cleaning is here to help. It is a specialized method that effectively cleans and protects roofs from mold, mildew, grime, and other irritants.

What Is Softwashing, and How Is It Different From Pressure Washing a Roof?

Softwashing differs from pressure washing, the other commonly used roof cleaning technique. While both methods aim to remove dirt and stains, softwashing takes a gentler approach. It utilizes specialized detergents and low-pressure water to clean the roof, ensuring that delicate materials like shingles or tiles are not damaged. This technique effectively eliminates dirt, grime, algae, and stubborn stains.

In contrast, pressure washing employs high-pressure water jets to forcefully blast away debris. Although pressure washing can be effective, it can also be harsh on fragile roofing materials like asphalt shingles.

Before deciding between softwashing and pressure washing, it’s advisable to seek professional advice based on your roof type and the level of cleaning required.

Advantages of Soft-Washing for Roofs:


By now you will be thinking, what are its advantages? Well then let’s take a look.

  • Gentle on Roof Materials: Softwashing ensures that cleansing materials do not damage or dislodge shingles or tiles. By avoiding the use of harsh chemicals and rough scrubbing, it helps roofs last longer and maintains their appearance.
  • Effective Removal of Algae, Mold, and Mildew: Softwashing eliminates algae and prevents further growth. Algae can cause black streaks and damage shingles over time. Softwashing combines biodegradable detergents and low-pressure water streams to remove existing algae effectively.
  • Increases Roof Lifespan: The gentle cleaning method prolongs the life of the roof. Pressure washing, on the other hand, can strip away protective coatings and damage shingles. Softwashing removes debris without harming the roof, including corrosive organisms like moss and algae.
  • Cost-Effective Alternative to Roof Replacement: Softwashing services offer a more affordable option compared to roof replacement, which can be a costly endeavor. Softwashing provides quality cleaning without compromising on cost.

Drawbacks and Risks:

Like any cleaning method, softwashing has some potential drawbacks and risks. It may not remove all stains completely, leaving some dirt behind. Improper cleaning by an inexperienced or untrained specialist can lead to surface damage or water penetration. However, these inconveniences and hazards can be minimized by working with a knowledgeable and experienced professional.

Comparison Between Pressure Washing and Soft-Washing:

When comparing, several factors come into play:

  • Upfront and Maintenance Costs: Pressure washers are initially cheaper, but their maintenance costs can add up due to regular tune-ups and part replacements. Softwash systems are more expensive initially, but have lower maintenance costs thanks to their gentle cleaning method.
  • Time Consumption: Pressure washing can be time-consuming, especially for larger areas or tougher grime, as it relies on force rather than chemicals. Softwashing, with its effective cleaning solutions, can cover large areas more quickly and efficiently, saving valuable time.
  • Additional Factors: Pressure washing can potentially damage softer or older surfaces due to its high force. Softwashing, with its lower pressure, is generally safer for delicate areas. However, caution should be exercised while handling the cleaning solutions used in softwashing.

It’s important to consider costs, timing, efficiency, and safety when deciding between these two. The cheapest solution may not always be the most cost-effective in the long run. Choose carefully based on the specific requirements of your house.
