Never Brush Moss From Asphalt Shingles

Lots of companies make money by brushing roofs and returning for more moss cleaning jobs. However, we believe your roof deserves better care. That's why you won't see Chinook Services using roof brushing near Seattle. Instead, we've created our gentle soft wash moss service with a 5-year warranty because your roof deserves special attention, and you've come to the right place with Chinook.


Why no brush moss roof cleaning

Roof cleaners aggressively brushing moss from Seattle area roof. Workers have no fall protection, this is exactly what you want to avoid.


You Should NEVER Brush Off Live Moss From Your Roof

The top layer of the roof has tiny granules that will come loose when you brush. Live moss won't be killed by brushing; instead, it will spread all over your property, including your lawn, garden beds, decks, and walkways. On a smaller scale, brushing moss can be worse than doing nothing because it scatters tiny spores everywhere, turning you into a moss farmer unintentionally.

It's pretty simple. Chinook always follows the rules from top roof producers when it comes to getting rid of moss on your roof. We want to be clear: these roof producers say you should NEVER use a brush to clean moss because it will cancel your warranty and shorten your roof's life by a lot. Why does this matter? Well, think about it. A typical Seattle roof costs about $22,900. So, it's smart to stick to the rules and make sure your roof lasts as long as it's supposed to, like 20, 25, 30, or even 50 years, just as it was meant to.

Seattle Area Roof Cleaning Moss Removal Testimonials

Locally Seattle Owned and Operated

My name is Jay, the heart and soul behind Chinook Services. For over 25 years, I've dedicated myself to mastering the art of roof cleaning in the evergreen city of Seattle. My journey is not just about cleaning roofs; it's about innovating and preserving, about changing the way we care for our homes in this beautiful city.

Humble Beginnings Roof Cleaning in Seattle

It started in the University District, working closely with the University of Washington. Those formative years were crucial; pressure washing numerous properties catalyzed a major expansion for Chinook Services. Consequently, we invested in large-scale cleaning equipment that was adaptable enough to handle both expansive commercial properties and the charming homes of Seattle.

The Discovery of Soft Wash Roof Cleaning

In Seattle, roof cleaning is a unique challenge. The persistent moss, especially on the prevalent asphalt shingled roofs, demanded a special approach. I learned that the key was not just in the tools, but in the methods. Following the guidelines from roofing producers, we adopted the soft wash method, a game-changer in roof maintenance.

The Seattle Soft Wash Roof Cleaning Revolution

The days of aggressively pressure washing or brushing roofs are behind us; I realized such methods were too harsh. The granular top layer of asphalt shingles, which is quite delicate, could be easily damaged by these aggressive techniques. Now, at Chinook Services, we are committed to respecting this vulnerability. Thus, we have adopted the use of a bleach-based cleaning agent in our soft wash process, which guarantees effective cleaning without inflicting damage.

Educating Roof Cleaning in Seattle and Leading by Example

I recall a day in Laurelhurst, demonstrating the soft wash method to a fellow roof cleaner. The difference was clear. Brushing not only damages the roof but also spreads moss spores, leading to more growth. Our method at Chinook Services kills moss instantly, preventing regrowth and protecting the entire property.

 A Promise of Quality Seattle Roof Cleaning

At Chinook Services, we stand by our work with a 5-year no new moss warranty. We've seen the pitfalls of aggressive cleaning methods and have vowed never to brush an asphalt roof. Our approach is about long-term care, not just instant results.

We Care about Seattle Roof Cleaning

From the University District to Laurelhurst, our journey in Seattle has been about more than cleaning roofs; it's been about setting a new standard in roof care. To the residents of Seattle, we offer not just a service, but a commitment to excellence and sustainability. Choose Chinook Services, and experience the difference of a roof cleaned with care and expertise.

Mastering Moss Roof Cleaning: A Must for Seattle Homeowners

In the moist climate of Seattle, WA, moss thrives, underscoring the importance of roof cleaning for homeowners. As the owner of Chinook Services, situated in the heart of the moss belt, I have witnessed firsthand the problems moss can cause. It's more than just a cosmetic issue; moss can inflict serious damage on your roof if not managed correctly. In Seattle, roofs are particularly susceptible to moss due to their continuous exposure to the elements and challenging maintenance. This problem also extends to driveways, patios, and even garden beds, affecting various aspects of your property.

Effective Moss Removal Strategies: Roof Cleaning Seattle

Moss, scientifically known as Bryophyta, thrives in moist, shady environments and is unique because it lacks the vascular tissue found in many other plants. Consequently, it grows in dense green clumps or mats in damp locations. Online scientific data reveal that moss absorbs water and nutrients primarily through its leaves instead of roots. This unique absorption method enables moss to quickly colonize surfaces, which can lead to potential damage if not properly managed.

Understaning Characteristics of Moss

By understanding these characteristics, we emphasize the importance of targeted treatment for effective moss management. Thus, addressing moss at its source ensures a comprehensive approach to maintaining the health and aesthetics of your outdoor spaces.

Moss Spreads, Why Spread It?

Many overlook the scientific aspects of moss, failing to grasp the importance of addressing it correctly before removal. Moss reproduces through microscopic spores, which, if merely brushed or power washed without prior treatment, can swiftly scatter across your property and lead to rapid regrowth. At Chinook Services, we prioritize the correct techniques for moss removal, ensuring effective and long-lasting results.

Stop Say No To Moss Growth 

At Chinook Services, we employ environmentally friendly solutions or specialized treatments, thereby ensuring effective moss management. This strategy not only halts future growth but also preserves the structural integrity of your roof. Proper moss management is essential, enhancing both the aesthetic appeal and the durability of your property. When you next spot moss, be sure to tackle it at its roots for complete removal.


Your Satisfaction is Guaranteed

With more than 2,000 "5 star" or "A" rated reviews on Angie’s List, Google Reviews, Yelp, and The Better Business Bureau, Chinook’s commercial and residential cleaners offer a 100% satisfaction guarantee! When you schedule a Seattle roof cleaning service know that you are in good hands!
