Roof Moss Removal Nanaimo
Soft Wash Treatment & Prevention
Roof moss removal in Nanaimo treats moss living on asphalt, cedar, and metal roofs. The soft wash reaches the growth without blasting granules off shingles. A general soft wash for algae and lichen is roof cleaning in Nanaimo.
Why Moss Is a Serious Problem on Vancouver Island
Nanaimo receives over 1,100mm of rain per year. That moisture, combined with shade from the island's tree coverage, creates ideal conditions for moss to thrive on roofs, driveways, patios, and fences. Left untreated, moss on a roof retains moisture against shingles — causing rot, lifting, and leaks. On driveways and paths, it creates dangerous slip hazards. Regular moss removal protects your property and prevents costly repairs.

Our Method
Why We Use Soft Washing for Moss Removal
High-pressure washing blasts moss off the surface — but leaves the roots behind. Within months, the moss regrows. It also strips shingle granules, voids roofing warranties, and can force water into wall cavities.
Soft washing uses low pressure combined with biodegradable, moss-killing solutions that penetrate to the root structure and kill the organism entirely. Results last 2–5 years on roofs and 1–3 years on hard surfaces — significantly longer than pressure washing alone.

Common Questions
Moss Removal FAQs — Nanaimo
How much does moss removal cost in Nanaimo?
Moss removal in Nanaimo typically ranges from $200–$700 depending on the surface area, type of surface (roof, driveway, patio), and severity of growth. Roof moss removal is the most common and starts around $300. We provide free, no-obligation quotes — call 778-744-4021.
What method do you use for moss removal in Nanaimo?
We use soft washing — a low-pressure technique combined with biodegradable, moss-killing solutions. This kills moss at the root rather than just scraping the surface, which means results last significantly longer. We never use high-pressure washing on roofs or delicate surfaces as it damages shingles and voids warranties.
How long does moss removal last?
Soft wash moss removal typically lasts 2–5 years on roofs and 1–3 years on driveways and patios, depending on shade, moisture exposure, and tree coverage. We also offer zinc strip installation after roof moss removal to slow future regrowth. Nanaimo's wet climate means ongoing maintenance is the best long-term strategy.
Is moss on my roof actually damaging it?
Yes. Moss roots penetrate between shingle granules, retaining moisture and causing rot, lifting shingles, and accelerating shingle wear. Over time, untreated moss can lead to leaks and significantly shorten your roof's lifespan. Moss removal is one of the best investments you can make to protect your roof.
Can you remove moss from driveways and patios in Nanaimo?
Absolutely. Moss and algae on concrete, brick, and paving stone surfaces become extremely slippery when wet — a serious safety hazard. We pressure wash and treat these surfaces to remove moss completely and apply treatments that inhibit regrowth.
Do you serve areas outside Nanaimo for moss removal?
Yes — Moss Bros. provides moss removal throughout Nanaimo, Parksville, Lantzville, Ladysmith, Cedar, Qualicum Beach, North Nanaimo, and surrounding Vancouver Island communities.
What is a zinc strip and does it really prevent moss regrowth?
Yes — zinc strips are highly effective at slowing moss regrowth. When it rains, zinc oxide leaches down your roof and creates an environment hostile to moss growth. We install zinc strips at the ridge after every roof moss removal job. Combined with our soft wash treatment, most Nanaimo roofs stay moss-free for 3–5 years.
Is moss on my driveway dangerous in Nanaimo?
Absolutely. Moss and algae on concrete and stone become extremely slippery when wet — one of the leading causes of falls and injuries on residential properties. Nanaimo's 1,100mm+ annual rainfall means moss-covered driveways and paths are a serious hazard from October through April. Regular moss removal treatment keeps your surfaces safe and slip-free.
