Bothell Moss Removal: What’s the Best Treatment for Your Roof?

Many homeowners in Bothell ask us about the best way to remove moss from their roofs. The answer is simple: professional soft washing. Using a soft wash spray is the safest and most effective method to eliminate moss without causing damage.

Look closely at the photo of a Bothell roof treated with our soft wash solution. You’ll notice that the moss mainly resides on the edges of the shingles. Trying to remove this moss by brushing can be problematic because it strips away the top layer of ceramic granular material on the shingles. This damage is often invisible from the ground, leading homeowners to pay extra for brushing, which may make the roof look clean. However, up close, the damage is significant — it not only removes the top layer of ceramic granular material but also weakens the bond between the shingles and the granules, accelerating deterioration. Soft washing avoids this damage, preserving the integrity of your roof while effectively removing moss.

Why Proper Moss Removal Matters for Your Bothell Roof

Did you know that replacing a roof in Bothell can cost $14,000 or more? That’s why proper moss removal is essential — it can significantly extend your roof’s lifespan. Unlike companies that use brushes or aggressive scrubbing, we never harm your shingles. Most roofs in Bothell are asphalt shingles with a protective granular surface. Again, scrubbing can strip away these granules, weakening your roof’s ability to protect against UV rays, rain, and snow. Additionally, brushing can void your roof warranty and goes against the manufacturer’s cleaning guidelines. Why ignore the very instructions designed to preserve your roof?

The Best Method for Bothell Moss Removal

Our soft wash spray effectively kills moss and allows it to naturally break down, leaving your roof clean without losing protective granules. The attached photo shows a 40-year-rated asphalt roof after treatment — notice how the moss turns white, and weather naturally rinses it away over time.

The Important Top Layer of Asphalt Shingles

A top layer of ceramic granules on asphalt shingles serves a crucial function in protecting your roof. These granules give the shingles their color and aesthetic appeal, ensuring your roof looks attractive year after year. More importantly, they act as a vital shield against the sun’s harmful ultraviolet (UV) rays. Embedded into the asphalt, these granules reflect and absorb UV radiation, slowing down the aging process of the shingles and helping to prevent premature deterioration.

Preserving this granular layer is essential because once it’s compromised, the roof becomes vulnerable to damage. Harsh cleaning methods, such as power washing or aggressive scrubbing, can easily dislodge or strip away these granules. When the granules are lost, the asphalt layer underneath is exposed, making it more susceptible to UV damage, weathering, and water infiltration. Over time, this deterioration can cause shingles to become brittle, crack, or break apart, significantly shortening the lifespan of your roof.

The granular material is securely attached to the asphalt shingles through a process during manufacturing, where ceramic or mineral granules are embedded into the hot asphalt layer while the shingles are still in a semi-liquid state. As the asphalt cools and hardens, it forms a strong bond with the granules, effectively anchoring them in place. This attachment ensures they stay on throughout the roof’s lifespan, providing ongoing protection and color retention. However, this bond can be weakened or broken if the shingles are subjected to abrasive cleaning techniques. That’s why gentle, specialized cleaning methods like soft washing are crucial—they remove moss and dirt without damaging the granular layer or sacrificing your roof’s durability.
