Soft wash roof cleaning is a specialized cleaning technique designed to gently and effectively remove dirt, stains, moss, algae, and other contaminants from roofs. Unlike traditional high-pressure methods, soft washing utilizes low-pressure water combined with specially formulated, eco-friendly cleaning solutions.

These solutions break down and kill organic growth at the root, ensuring a thorough clean without causing damage to delicate roofing materials such as asphalt shingles, wood, or tiles. Soft wash roof cleaning not only restores the roof’s appearance but also inhibits the regrowth of contaminants, prolonging the cleanliness of the surface.

Soft Wash Roof Cleaning Process

The soft washing process involves the following steps:


The first step is to assess the condition of the roof, identifying the type of contaminants present and the roofing material. This assessment helps in choosing the appropriate cleaning solution and technique.


The area around the house is prepared for the cleaning process. This may include covering plants, securing windows, and ensuring that the surrounding area is protected from the cleaning solution.

Application of Cleaning Solution:

A specially formulated cleaning solution, which is typically a mixture of water, bleach, soap, and other biodegradable chemicals, is applied to the roof surface. These solutions are designed to kill algae, mold, moss, and other organic growth, breaking down and loosening the contaminants.

Dwell Time:

The cleaning solution is allowed to dwell on the surface for a specified period, typically 15 to 20 minutes. During this time, the solution penetrates the stains and works on breaking them down.

Low-Pressure Rinse:

After the dwell time, the roof is rinsed with low-pressure water. The rinsing process washes away the cleaning solution along with the loosened contaminants, leaving the roof clean and free from stains.


In some cases, a protective coating or sealer may be applied to the roof surface after cleaning. This helps in preventing the regrowth of algae, moss, or other contaminants, prolonging the cleanliness of the roof.


Soft washing roof cleaning is particularly suitable for delicate roofing materials such as asphalt shingles, wood shingles, and tiles. These materials can be easily damaged by high-pressure washing, making soft washing a safer and more effective alternative. Additionally, the use of specialized cleaning solutions ensures a thorough and long-lasting cleaning result while being environmentally friendly and safe for surrounding vegetation and wildlife.

It’s important to note that soft washing roof cleaning should be carried out by trained professionals who have the necessary equipment, expertise, and knowledge of the appropriate cleaning solutions. Proper safety measures and environmental considerations are essential to ensure a successful and eco-friendly roof cleaning process.

Benefits of Soft Washing:

 Soft Wash Treatment

Soft washing offers several benefits, making it a popular choice for cleaning various surfaces, especially delicate ones. Here are the key advantages of soft washing:

  1. Gentle Cleaning: Soft washing uses low-pressure water combined with specialized cleaning solutions, providing a gentle and non-abrasive cleaning method. It ensures that even delicate surfaces, such as roofs, siding, and painted walls, are cleaned thoroughly without causing any damage.
  2. Safe for Sensitive Materials: Soft washing is suitable for fragile materials like wood, vinyl, stucco, and decorative stonework. Unlike high-pressure methods, it doesn’t strip away paint, erode surfaces, or cause water infiltration.
  3. Effectively Removes Contaminants: The specially formulated cleaning solutions used in soft washing effectively remove dirt, grime, mold, algae, and other contaminants from surfaces. These solutions are designed to break down and kill organic growth at its root, ensuring a long-lasting clean.
  4. Prevents Damage: Traditional pressure washing can force water under siding, shingles, or cracks, potentially causing damage. Soft washing prevents water intrusion and minimizes the risk of structural damage by using a controlled spray and mild cleaning agents.
  5. Long-Lasting Results: Soft washing not only cleans the surface but also hinders the regrowth of mold, algae, and other contaminants. This results in a cleaner surface for a more extended period compared to traditional high-pressure cleaning methods.
  6. Versatility: Soft washing is versatile and can be used on a wide range of surfaces, including roofs, sidings, decks, fences, and outdoor furniture. Its adaptability makes it an excellent choice for various cleaning needs.
  7. Cost-Effective: In the long run, soft washing can be cost-effective because it prevents the need for frequent cleanings. By inhibiting the growth of contaminants at the root, it extends the time between cleanings, saving homeowners and businesses money over time.
  8. Curb Appeal: Soft washing enhances the curb appeal of homes and businesses by restoring surfaces to their original, clean state. A well-maintained exterior not only looks appealing but also increases the property’s value.

In summary, soft washing offers a safe and effective solution for cleaning a variety of surfaces, making it a preferred choice for many homeowners and businesses.
