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.
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.

Our condominium building chose Coastal Shores based on a competitive bid, good reviews, and being a small family owned business. Paul and his crew were fantastic and did an impeccable job, especially tackling the seagull poop on the top floor windows!Posted on Google![]()

We are always super happy with the work that Paul does for us. He has power washed our long driveway, and cleaned the patio and the deck. He has cleaned windows. Today he got needles and cones off the roof. We feel that Paul treats our property as he would treat his own. We will definitely use Coastal Shores again and will recommend him to family and friends.Posted on Google![]()

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. For moss removal in Victoria BC, Coastal Shores is the best choice.
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.
Coastal Shores Window Cleaning is proud to be the trusted local exterior cleaning company for homeowners and businesses throughout the Greater Victoria region. Based in Victoria, our expert teams cover the entire Capital Regional District, ensuring comprehensive and prompt service regardless of your location.

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.

Yes. Major shingle manufacturers, including CertainTeed and IKO, explicitly exclude damage caused by organic growth from their warranty coverage. This means that if moss has deteriorated your shingles and you make a claim, the manufacturer can deny it. Attempting to remove the moss yourself with a pressure washer can make things worse — the high-pressure blasting strips granules from the shingles, which is another common warranty exclusion.
For the full picture on how moss damages shingles and affects your insurance, see our in-depth guide.
DIY moss removal is possible, but there are real risks. Pressure washing is one of the most common ways homeowners accidentally void their shingle warranty. Manual scraping can also lift shingle laps and break sealants. Store-bought zinc strips provide some prevention but don’t address existing growth. If your roof is still under a manufacturer warranty or if your insurer has flagged the moss, a professional treatment is the safest option.
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.
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.
