Soft washing - the preferred method for cleaning roofs

by AM Property Services

July 2023
Soft washing is a highly effective and innovative approach to cleaning and revitalising roofs, siding and other exterior surfaces. Unlike traditional pressure washing, which relies on high-pressure water to forcefully remove dirt, grime and contaminants, soft washing utilises a unique combination of low-pressure water application and specially formulated cleaning solutions to achieve thorough and gentle cleaning results. This method is particularly well-suited for cleaning delicate surfaces such as roofs, which can be prone to damage from high-pressure water streams.
The soft washing process involves a series of meticulously executed steps that ensure comprehensive cleaning while safeguarding the structural integrity and aesthetics of the treated surface:

1. Assessment and preparation
The soft washing process begins with a thorough assessment of the roof's condition, type of material and the extent of contamination. Experienced roof cleaning professionals determine the appropriate cleaning solution and method based on these factors. Adequate safety measures are put in place to protect both the technicians and the surrounding environment.

2. Application of cleaning solution
A biodegradable and environmentally friendly cleaning solution is prepared based on the type of contaminants present. This solution is specially designed to break down and dissolve organic growth such as algae, moss, lichen, mildew, dirt and stains. The solution is applied evenly to the roof surface using low-pressure equipment, ensuring complete coverage.

3. Dwell time
One of the distinguishing features of soft washing is the "dwell time." After the cleaning solution is applied, it is allowed to remain on the surface for a specific period, usually around 15 to 20 minutes. This dwell time is crucial, as it allows the cleaning solution to penetrate deep into the contaminants, effectively breaking down their structure.

4. Cleaning action
During the dwell time, the cleaning solution actively interacts with the contaminants, dissolving their bonds and weakening their grip on the surface. This process makes it much easier to remove the contaminants without the need for high-pressure water.

5. Low-pressure rinse
After the dwell time has passed, a low-pressure water rinse is performed to wash away the cleaning solution along with the loosened contaminants. The low-pressure rinse is gentle enough to avoid damaging the roofing material while still achieving a thorough clean.

6. Inspection and final touches
Following the rinse, the cleaned surface is carefully inspected to ensure that all contaminants have been effectively removed. Any remaining spots or areas are given additional attention. If necessary, a second application of the cleaning solution and rinse may be performed for stubborn areas.

7. Protection and prevention
In addition to cleaning, some soft washing solutions include protective agents that help prevent the regrowth of algae, moss and other contaminants. This proactive approach ensures that the roof remains cleaner and free of growth for an extended period.

Benefits of soft washing roofs

Soft washing can restore the appearance of a roof by removing unsightly stains and streaks caused by organic growth. Soft washing is the preferred choice by roof cleaning professionals as it is safe for a variety of roofing materials, including asphalt shingles, tiles, metal and more. It doesn't cause surface damage or dislodge shingles, which can happen with high-pressure washing.

Soft washing solutions are designed to be environmentally friendly, minimising the impact on surrounding vegetation and water sources. The specialised cleaning solutions used in soft washing can also inhibit the regrowth of algae and other contaminants, resulting in a cleaner roof for a longer period of time.

Soft washing roofs is a job for the professionals

It's important to note that soft washing is a specialised process that should be carried out by trained professionals. If you're considering soft washing for your roof, it's recommended to hire a reputable and experienced roof cleaning company to ensure that the cleaning is done safely and effectively.

Why do roofs need to be cleaned?

Roof cleaning is an essential maintenance task that offers numerous benefits for both the appearance and structural integrity of your property. Over time, dirt, algae, moss, lichen and other debris can accumulate on the roof's surface. These contaminants can trap moisture, which can lead to the deterioration of roofing materials. This can compromise the roof's integrity, leading to leaks, water damage and even structural issues if left unchecked. Regular cleaning helps prevent this moisture retention, thereby extending the lifespan of your roof. Debris accumulation on the roof can also create hiding spots and pathways for pests such as insects, birds and rodents. Regular cleaning helps deter these pests from making your roof their home.

A clean roof also significantly improves the overall curb appeal of your property. Stains, streaks, and discolouration caused by algae or moss growth can make your roof look old and unkempt. Cleaning restores your roof's original colour and enhances the visual appeal of your home. A well-maintained roof can significantly boost the value of your property. Potential buyers and estate agents often take the condition of the roof into consideration when determining the value of a home.

In summary, roof cleaning is not just about aesthetics; it's about protecting your investment and ensuring the long-term health and integrity of your home. Regular roof cleaning can extend the life of your roof, enhance its appearance and contribute to the overall well-being of your property.

In conclusion, soft washing is a sophisticated and gentle approach to cleaning roofs that delivers exceptional results without causing damage to the roofing materials. Its environmentally friendly cleaning solutions, proactive prevention of future growth and preservation of the roof's structural integrity make it an excellent choice for maintaining the appearance and health of your home's exterior. It's highly recommended to engage the services of trained and experienced professionals to ensure that the soft washing process is carried out safely and effectively.
