Understanding the Need for Soft Wash Roof Cleaning

Soft wash roof cleaning, a revolutionary method of maintaining the cleanliness and aesthetics of your roof, is fast gaining popularity among homeowners and property managers. The technique employs biodegradable, yet potent cleansing agents, along with low-pressure water jets to clean the roof surfaces. This blog will provide an in-depth look into soft wash roof cleaning, how it differs from traditional methods, its key advantages, and the overall process.

What is Soft Wash Roof Cleaning?

At its simplest, soft wash roof cleaning is a gentler alternative to conventional high-pressure washing. It uses a combination of specially designed cleaning solutions and lower water pressure to effectively remove debris, mold, algae, and other pollutants from your roof without causing unwanted damage.

The Distinction Between Soft Wash and Pressure Washing

One of the primary differences between soft washing and high-pressure washing lies in the force with which water is applied. While pressure washing relies on the power of water to dislodge impurities, soft washing depends mostly on the cleaning solution's strength to eradicate dirt and grime. This non-abrasive approach helps protect your roof materials against possible harm or degradation.

Benefits of Soft Wash Roof Cleaning

  • Less Abrasive: As mentioned earlier, soft washing doesn't involve harsh water pressure, which drastically reduces the risk of damaging your roof.

  • Effective Cleaning: Soft washing uses biodegradable agents that are highly capable of annihilating biological elements like mold, algae, mildew, and lichen, ensuring deeper and longer-lasting cleaning.

  • Eco-Friendly: The cleaning solutions used in soft washing are biodegradable, making them better for the environment compared to many harsh detergents.

The Soft Wash Roof Cleaning Process


The first step in the soft wash roof cleaning process is assessment. Professionals will determine the type and extent of impurities and select the most suitable biodegradable cleaning solution for your roof.


Once the assessment is complete, professionals will spray the roof with the selected cleaning solution. This is generally applied with a low-pressure spray to prevent any damage to the roofing material.


After the cleaner has had sufficient time to break down the dirt and biological growth, it is then gently rinsed off with a low-pressure water jet, leaving your roof clean and pollution-free.

Elevate Your Roof's Appeal with Soft Wash Roof Cleaning

If your roof looks old and tarnished due to dirt, algae, or mildew, soft wash roof cleaning can reinstate its appeal and prolong its lifespan. Not only is this method effective for deep cleaning, but it is also less harsh on your roof and more eco-friendly than traditional cleaning methods. Thus, homeowners in search of an efficient, safe, and environmentally conscious roof cleaning method can confidently turn to soft wash roof cleaning.

Your roof not only serves an aesthetic purpose but also plays a significant role in safeguarding your home. Therefore, using an efficient, gentle, and effective cleaning method like soft wash is essential to maintaining your roof's condition and durability.

FAQs on Soft Wash Roof Cleaning

What differentiates soft wash roof cleaning from pressure washing?

Soft wash roof cleaning and pressure washing are two distinct methods of cleaning a roof. Soft washing uses a low-pressure cleaning solution to gently remove dirt, algae, and grime from your roof without damaging the roof materials. On the other hand, pressure washing involves high-pressure water spraying that can harm delicate roof materials, particularly on older roofs.

Is soft wash roof cleaning safe for all types of roofs?

Most definitely. The low-pressure approach in soft wash roof cleaning is safe for all types of roofing materials, including asphalt shingles, metal, tile, slate, and wood shakes. Its technique ensures that it does not cause any damaging abrasion to the roof materials.

Will soft wash roof cleaning remove moss, algae, and lichen from my roof?

Yes, a primary advantage of soft wash roof cleaning is its effectiveness in eliminating moss, algae, lichen, and other organic growths. The cleaning solutions used in soft washing are designed to kill these organisms at their root, preventing their quick return.

Do I need to prepare my roof for soft wash roof cleaning?

Not necessarily. Soft wash roof cleaning professionals should be able to handle the entire cleaning process. However, it's always good to remove any loose debris from your roof and to ensure that the cleaning crew has easy access to your roof.

How long does soft wash roof cleaning typically take?

The length of the soft wash roof cleaning process can vary significantly depending on the size and condition of your roof and the level of infestation of moss, algae, lichen, etc. However, on average, most soft wash roof cleaning projects can be completed within a few hours.

How often should I have a soft wash roof cleaning done?

The frequency of soft wash roof cleaning depends on several factors including your geographic location, the amount of tree coverage near your home, humidity levels, and the age of your roof. In areas prone to heavy moss, algae, and lichen growth, yearly soft wash roof cleaning might be necessary. In other regions, every 2-3 years could be sufficient.

Could I perform soft wash roof cleaning myself?

While it is possible to perform soft wash roof cleaning yourself, it is generally recommended to hire a professional. Professionals have the proper training and equipment to safely and effectively clean your roof, minimizing the risk of personal injury or potential damage to your property.

How does soft wash roof cleaning benefit the longevity of my roof?

By eliminating harmful organisms like algae, moss, and lichen, soft wash roof cleaning helps mitigate the damage these organisms can cause, such as roof decay and loosening of roof materials. Thus, regular soft wash roof cleaning can prolong the life of your roof, saving you costly replacements in the long run.

Are the chemicals used in soft wash roof cleaning environmentally friendly?

Soft wash roof cleaning solutions are typically biodegradable and eco-friendly. They specifically target organic growths and are safe for use around pets and plants. However, depending on the company, the precise formulation of the cleaning solution might differ. It's best to discuss this with your chosen service provider.

How soon can I see results after a soft wash roof cleaning session?

You should be able to notice an immediate difference on your roof after a soft wash roof cleaning session. All dirt, grime, and most organic growth should be removed by the end of the cleaning. However, for heavily infested roofs, full results might be noticeable within a few days to a week as the cleaning solution continues to kill off any remaining organisms.

Pros of Soft Wash Roof Cleaning

Extended Roof Lifespan

Soft wash roof cleaning could extend the lifespan of your roof. Unlike power washing, which could potentially damage the shingles through high-pressure water output, soft washing relates to a gentler water pressure, preserving the integrity of the shingles and thereby increasing their lifespan.

Eco-Friendly Method

  • Biodegradable cleaning agents: Soft wash roof cleaning typically uses environmentally-friendly and biodegradable cleaning solutions. These don't harm plants, pets or your family, unlike traditional harsh chemical cleaners.

  • Water Conversation: Since soft wash roof cleaning requires a lower volume of water compared to other methods, it plays a role in water conservation.

Effectiveness Against Algae, Moss, and Molds

Infestations from organisms like algae, moss, and molds can damage roofing materials. Soft wash roof cleaning excels at wiping out these biological elements without the risk of damaging the roof materials.

Safe Cleaning Technique

The reduced pressure levels employed in soft wash roof cleaning make it a safer cleaning technique, minimizing the risk of injuries and accidents, and reducing potential damage to the roof.

Enhancement of Aesthetics and Property Value

Soft wash roof cleaning can make your roof look as good as new and enhance the overall aesthetics of the property. Moreover, a well-maintained roof can boost the value of the property.

Cons of Soft Wash Roof Cleaning

Professional Assistance Required

While it might be tempting to try your hand at soft wash roof cleaning, the process calls for professional assistance. This is primarily because the chemicals used, if not handled correctly, can be hazardous. Furthermore, climbing a roof without proper safety measures can pose a risk of injury.

Upfront Cost

  • Although soft wash roof cleaning can save you money by extending the lifespan of your roof, the initial cost can be higher than other cleaning methods.

  • Additionally, if chosen to hire a professional service, a significant chunk of the budget goes towards their service charges.

Not Suitable for Heavily Soiled Roofs

Soft wash roof cleaning might not be the best choice for roofs with severe dirt and soot accumulation. The low pressure may not effectively remove aggressive grime or stubborn stains.

Repeated Applications

Compared to power washing, soft wash roof cleaning may require repeated applications to remove persistent growths. This could be a time-consuming process and might also demand additional costs.

Incorrect Process can Damage Roof

If not conducted properly, soft washing can lead to application of too much chemical cleaning agents. This can potentially harm the roofing material, particularly if it's not rinsed thoroughly after application. Therefore, this method requires careful handling and execution.


Soft wash roof cleaning is a must-have for homeowners looking for a safe and effective way to preserve their roofs' quality and life span. It works wonders in removing dirt, grime, algae, and other harmful substances that can damage the roof or compromise its appealing look. With this method, you can enjoy a cleaner and more radiant roof without worrying about potential damages caused by aggressive cleaning methods.
