Moss Removal Services in the Greater Victoria Area

Moss can be very pleasing in specific settings. However, moss on a roof can have devastating consequences for property owners. Unlike other areas of your property, we can not remove moss on your roof using pressure. As moss grows, it can wedge under your shingles, causing gaps and holes that a pressure washer can exacerbate. Therefore, it is essential to have the knowledge, skill, and experience to use the correct methods and techniques when dealing with organic growth. Coastal Shores employs various practices, such as pressure washing, soft washing and green chemicals treatments. This allows us to remove moss, algae, mildew and mould from almost any surface safely and effectively.

Roof Moss Removal In Victoria

Does your home have a mossy roof? There’s a good chance it does, given our wet West Coast weather. Some Greater Victoria communities, such as Sidney or the West Shore, have additional moisture from the ocean that can promote moss growth.

Demossing Driveways, Walkways, and Patios

Moss and algae on hardscaping are not just unsightly—they are a serious slip-and-fall hazard, especially during Victoria’s wet season. Our approach to cleaning driveways, sidewalks, and patios involves a gentle but effective method that restores curb appeal without damaging your concrete or pavers.

Unlike roofing, these durable surfaces often benefit from a low-pressure wash combined with our eco-friendly treatment. This specialized process lifts the embedded growth from the pores of the stone, asphalt, or cement, leaving your high-traffic areas safe and looking brand new.

Deck Cleaning

Deck and Fence Demossing & Surface Protection

In the Pacific Northwest, wooden structures like decks, railings, and perimeter fences are prime targets for organic growth. Moss acts like a sponge, trapping moisture against the wood and accelerating rot, warping, and premature deterioration.

Our technicians are trained to assess the specific wood type (cedar, pressure-treated, etc.) before applying any treatment. We use a tailored, ultra-low-pressure soft wash to safely remove the moss and mildew, ensuring the structural integrity of your deck is preserved.

After demossing, we recommend a preventative treatment to inhibit regrowth. This maintenance not only restores the natural beauty of your wood but significantly extends the lifespan of your exterior investments.

More Moss Removal Tips

Moss Removal is commonly associated with roof maintenance and preventing costly repairs. However, moss and other Bryophyta can do more than destroy your roof. Moss acts as a sponge storing water creating rot on wooden surfaces such as decks, railings and even on your perimeter fencing. Additionally, it can cause corrosive water damage to stone, cement, brick and asphalt surfaces by exploiting tiny fishers. Finally, as the moss grows, it can expand these cracks causing lasting destruction to your property.

Hiring a professional moss removal company can protect you from unnecessary injuries. For example, removing moss from your roof can be a difficult and tedious process. Climbing up onto your roof and applying a chemical treatment can leave you standing on a slippery and treacherous surface. Here at Coastal Shores, we train our employees to use the correct fall arrest and, if possible, fall restraint systems. This ensures all parties are protected from very preventable injuries and headaches. Our employees are also highly trained in using our high-grade pressure washing and chemical treatment systems. This is also important to prevent injury when eradicating moss found elsewhere on your property.

Coastal Shores Window Cleaning is based in Oak Bay. However, we operate in a vast area throughout Greater Victoria, to which we offer free moss removal consultations. This includes Langford, View Royal, Saanich, Cordova Bay, Esquimalt, Colwood and Sooke. We provide a long-lasting, environmentally friendly solution to remove destructive moss, mildew, mould and algae from the exterior surfaces of your home.

Frequently Asked Questions About Moss Removal

How often should roofs be treated for moss in Victoria, BC?

Due to the persistent moisture on Vancouver Island, we recommend a full moss removal every 3-5 years with an annual preventative chemical treatment to maximize the life of your roof.

How much does roof moss removal cost in Victoria, B.C.?

The price for professional moss removal is highly dependent on your roof's size, pitch, and the density of the moss growth. Our services start at $550+ for smaller, standard-sized properties. We provide a custom, free quote after an on-site consultation to give you an accurate, fixed price, ensuring there are no surprises.

Is your moss removal method safe for my asphalt shingles?

Absolutely. We never use high-pressure washing on your roof, as it can severely damage shingles and void manufacturer warranties. Our process involves gentle, physical demossing by hand and brush, followed by a professional-grade soft wash and the application of a green chemical treatment. This method is safe, effective, and provides long-lasting protection against organic growth.

How often should I have my roof treated for moss in the Greater Victoria climate?

Due to the consistent moisture on Vancouver Island, we generally recommend a full moss removal service every 3 to 5 years. However, to maximize your roof’s lifespan, we advise a light annual or bi-annual preventative chemical treatment. This keeps new spores from taking root, protecting your investment from long-term damage caused by persistent West Coast rain.

What exactly does your 2-year Moss Removal Guarantee cover?

We stand behind the quality of our work with a 2-year guarantee against the re-establishment of significant moss growth. If noticeable moss returns within the two-year period following our service, we will return to your property and re-treat the affected area at no additional cost. This guarantee ensures peace of mind and proves our commitment to using the highest-quality, long-lasting products.

Does your moss removal service include cleaning out the gutters?

No, our dedicated Moss Removal service focuses specifically on the roof, decks, and other exterior surfaces. Gutter cleaning is a separate, specialized service. However, we highly recommend bundling the two services together. This ensures any debris, dislodged moss, or cleaning products are completely cleared from your eavestroughs and downspouts before we leave your property.
