What is Soft Washing?​

Soft washing is a sustainable, gentle, low-pressure cleaning method that utilizes biodegradable soap and detergent to treat and clean roofs, houses, buildings, walkways, and virtually any exterior surface. Unlike pressure and power washing—which use high pressure (up to 4000 PSI) that will damage your roof by blasting shingles off or cracking delicate Spanish barrel, flat concrete tile, or other roofing surfaces—soft washing employs gentle pressure, typically around 80 PSI. This method treats the surface for cyanobacteria, such as moss, mold, mildew, algae, and other contaminants, cleaning at a molecular level (up to 99.8% effective). As a result, your roofing or exterior surfaces remain clean for up to 4 to 6 times longer than with traditional pressure washing. Additionally, soft washing uses 66% less water and avoids the high-pressure damage often associated with pressure and power washing.

 

Most importantly, soft washing maximizes your roof’s lifespan and prevents bacterial deterioration of your siding and exterior surfaces. By eliminating destructive organic growth—such as moss, mold, mildew, algae, and other contaminants—that slowly feed on your roof and cause property decay, soft washing saves you money in the long run by preventing premature roof or siding replacement.

Has Your Homeowner’s Insurance in California Been Canceled or Requires a Soft Wash Low-Pressure Roof Cleaning for Renewal in the San Francisco Bay Area?​

Have you received a notice from your homeowner’s insurance company about moss, algae, mold, mildew, and cyanobacteria affecting your roof? Maxx ECO Wash is here to help you renew your policy smoothly. As a certified SoftWash Systems applicator, we specialize in the soft wash and low-pressure roof cleaning services required by insurance mandates. Our gentle cleaning process effectively mitigates moss, mold, mildew, algae, and the damage caused by these destructive bacterial contaminants, extending your roof’s lifespan to its full-rated potential.

​​

Does Moss, Mold, Mildew, Algae, and Cyanobacteria Decrease Roofing Lifespan by Half?

Yes, bacterial contamination on roofing surfaces can significantly reduce a roof’s lifespan—sometimes by as much as 50%. Organisms such as moss, mold, mildew, algae, lichen, and Gloeocapsa magma feed on asphalt shingles, cause rotting on cedar shake roofs, and their expanding root systems can lead to cracks in tile roofs. Regular maintenance and professional cleaning are essential to protect your roof and prolong its lifespan.

 

How Destructive is Moss, Mold, Mildew, and Algae for Your Roofing Material?

Many homeowners often feel that insurance companies are out to get them with notices regarding organic growth on their roofs. However, few realize the truly destructive impact of moss, mold, mildew, algae, gloeocapsa magma, and cyanobacteria on roofing materials. Before we specialized in this service, we too underestimated the importance of proper roof cleaning. In reality, these microorganisms thrive in microclimates like the San Francisco Bay Area and the Pacific Coast slowly feeding on the limestone in asphalt shingles, causing rot in cedar wood shake roofs, and potentially cracking Spanish barrel or flat tile roofs, among others. As a result, many homeowners find themselves replacing their roofs well before the end of their intended lifespan.

​

Our soft wash, low-pressure roof cleaning method eliminates these destructive bacteria at their roots, effectively extending your roof’s full-rated lifespan. Think of it like an oil change for your car: neglecting regular maintenance will eventually lead to engine failure, and the same concept applies to your roof and exterior siding.

​

In conclusion, soft wash low-pressure roof cleaning is an essential service that safely removes harmful growths—such as algae, moss, mold, cyanobacteria, and mildew—without damaging your roof. This method is vital for maintaining compliance with homeowner’s insurance requirements, as untreated microbial growth can significantly compromise the integrity of your roof, reducing its lifespan by nearly half.

Can You Pressure or Power Wash Your Roof?​

If you want to damage your roof, you can certainly pressure wash it. However, the correct answer is no—please do not use high-pressure or power washing on your roofing material, whether it’s asphalt shingles, tile, or wood shake. This method will cause severe, irreversible damage to your roof. It not only risks voiding your manufacturer’s warranty and compromising your insurance coverage, but it also jeopardizes the structural integrity of your roof by causing cracked tiles and dislodged shingles. Regardless of the vendor you choose, it is imperative that you avoid using pressure or power washing on your roof.

​

How Important is Roof Cleaning in the San Francisco Bay Area?​

Roof cleaning in the SF Bay Area is crucial not just for the aesthetics of your home but for maintaining the structural integrity and longevity of your roof. Much like changing the oil in your vehicle to keep the engine running smoothly or attending regular medical check-ups, routine roof cleaning is essential.

 

Your roof is constantly exposed to the elements, and over time, moss, algae, mold, mildew, and especially cyanobacteria can infest its surface. These contaminants gradually break down roofing materials, compromising the roof’s integrity.

 

Regular roof cleaning is akin to changing your vehicle’s oil—by removing harmful elements in a timely manner, you ensure your roof’s peak performance and extend its lifespan. This preventive maintenance helps avoid costly premature roof replacements, which can average $40,000 or more.

 

By soft washing your roof, you’re not just removing visible stains for appearance’s sake; you’re actively eliminating accumulated moss, algae, mold, mildew, and other contaminants that, if left unchecked, will deteriorate your roof over time. Just as changing your car’s oil protects the engine, soft washing your roof protects your property by enhancing its longevity, keeping the roof looking pristine, and, most importantly, preserving the property’s real estate value in the San Francisco Bay Area, CA​​

​

How Does Post-Rain Affect Roof Cleaning and Exterior Soft Washing?

• Rinsing Effect: Rain can act as a natural rinse for any remaining cleaning solution on the roof or house exterior. This can help to remove residual dirt, debris, or cleaning agents, providing a more thorough cleaning.​

• Streak Prevention: Rain can help prevent streaking by washing away any leftover cleaning solution, minimizing the chances of streaks or watermarks on the surfaces.​​

• Time-Saving: If the rain is substantial enough, it can assist in the cleaning process without the need for additional rinsing or manual efforts. This can save time and labor for both the cleaning professionals and homeowners.​

• Natural Water Conservation: Utilizing rainwater for the final rinse can be seen as a sustainable and cost-effective way to complete the cleaning process, as it doesn’t require additional water from other sources.

​

Why is Roof and Exterior Soft Wash Cleaning Important?

Roof and exterior soft washing cleaning is important for several reasons. First, it helps to maintain the aesthetic appearance of a property by removing unsightly stains, dirt, grime, and other contaminants from the exterior surfaces. This is especially important for commercial properties that rely on their appearance to attract customers.

​

Second, soft washing cleaning helps to protect the exterior surfaces from cyanobacteria damage caused by bacterial and fungal growth. As mentioned earlier, these contaminants can cause deterioration of the surfaces, leading to costly repairs and replacements.

​

Third, exterior soft washing cleaning helps to maintain the health and safety of the occupants of a property. Bacterial and fungal growth can pose health risks, especially to those with respiratory problems or weakened immune systems. Soft washing cleaning eliminates these risks by removing these contaminants.

​

Is Roof Washing and Exterior Low-Pressure Cleaning Effective?

​

The Science to Why Have Your Roof Cleaned and Exterior’s Soft-Pressure Washed in the San Francisco Bay Area?​

Gloeocapsa Magma, a type of cyanobacteria, is responsible for the growth of algae, moss, mold, mildew, and bacterial staining on roofs and exteriors. These ancient photosynthesizing organisms retain moisture, creating an ideal environment for mold, mildew, algae, moss, lichens, and fungi to thrive. This results in significant deterioration of roof and exterior surfaces, from granular loss on asphalt shingles to damage on concrete tile roofing, and even the rotting of exterior surfaces like wood and stucco, ultimately causing severe property damage.

 

To prevent such deterioration, it is crucial to treat surfaces with appropriate soaps and detergents that eliminate these bacterial growths at a molecular level. Maxx ECO Wash, powered by SoftWash Systems technology—a pioneer in soft washing for over 30 years—safely and effectively eliminates these bacterial contaminants, restoring the cleanliness of your roof and exterior to near-new condition. Our water-based and biodegradable cleaning solutions break down dirt and grime, removing mold, mildew, algae, moss, lichens, and other contaminants, thus prolonging the longevity of your property in San Francisco, San Jose, and the San Francisco Bay Area.
