Oak Bay's wet winters and mild, humid weather create ideal growing conditions for moss, which is exactly why so many roofs across Greater Victoria end up green long before the rest of the country.
From Oak Bay to Cadboro Bay to Gonzales, shaded and north-facing roofs trap moisture for months at a time. Moss takes hold in that damp environment, spreads under and between shingles, and holds water against the roofing material long after the rain stops.
Left untreated, that growth does real structural damage: it lifts and separates shingles, traps moisture that accelerates deterioration, and can shorten a roof’s lifespan by 10 to 15 years. Catching it early, and keeping it away, is far cheaper than a full replacement.
Our Roof Cleaning Process
A clear, methodical approach: from safe access to a fully cleaned-up worksite — so you know exactly what to expect.
Soft-wash solutions and hand-brushing remove moss and kill it at the root and spore level, so it doesn’t simply return next winter.
Our core service: gentle soft-wash and hand-brushing to remove moss and growth from family homes.
Office buildings, retail, and warehouses, scheduled around your operations with minimal disruption.
Specialised methods that clean metal surfaces effectively without harsh chemicals or scratching.
A two-step process: manual removal plus treatment that kills moss at the root and prevents regrowth.
Dirty panels lose 15–25% efficiency. We safely remove dust, pollen, and bird droppings to restore output.
A low-pressure method using specialised solutions, safe for shingles, tiles, and delicate roof surfaces.
We coordinate directly with property managers and councils for multi-unit and townhome complexes.
We also handle gutter cleaning, pressure washing, house washing, and window cleaning across Oak Bay.
Routine cleaning is one of the highest-return things you can do for your home. The math is simple: a clean roof lasts longer, and prevention costs a small fraction of replacement.
Real numbers, up front — we’d rather you know than guess. Our roof cleaning starts at $600. A 2,000 sq ft roof runs about $626 with light moss, or around $1,000 if it’s heavy. A 3,500 sq ft roof is roughly $1,000 to $1,800 depending on moss load. Only very large or extremely mossy roofs approach $3,000, and most homes are nowhere near that. Every quote is exact and no-obligation.
We’re Alex and Emma — a local husband-and-wife team, not a franchise. You deal with the owners directly, so you’re never just a number in a system. We’re genuinely part of this community (our customers have baked us muffins, and one even donated sod for our garden), and we know Oak Bay’s neighbourhoods, climate, and roofs. Here’s where we work.

Our roof cleaning starts at $600. As a rough guide: a 2,000 sq ft roof is about $626 for light moss or ~$1,000 if it's heavy; a 3,500 sq ft roof runs $1,000–$1,800; and only very large or extremely mossy roofs approach $3,000. Every quote is exact and no-obligation. Roof cleaning costs more than it looks because it's labour-intensive, done safely at height, and includes the treatment product and a full haul-away cleanup.
Yes. Moss lifts and separates shingles, traps moisture against the roofing material, and can lead to wood rot — shortening your roof's lifespan by 10 to 15 years. On an average roof here we remove 20 to 40 kg of it, so catching it early really matters.
No. High-pressure washing strips protective granules off shingles and forces water underneath, causing the exact damage we're hired to prevent. We use gentle soft-wash solutions and careful hand-brushing instead. Be cautious of cheap operators who rush the job with a metal brush and no fall protection — that's how roofs and gutters get wrecked.
If moss returns within 24 months of your roof cleaning service, we'll come back and re-treat your roof at no charge. Our treatment kills moss at the root and spore level, and we stand behind that work. Here's what a professional roof cleaning includes.
Because of Oak Bay's wet, humid climate, most roofs benefit from a professional cleaning and moss treatment every couple of years. Shaded and north-facing roofs that stay damp may need attention more often. A quick inspection tells us exactly what your roof needs. Timing matters too, so read up on the best time of year to remove roof moss.
Yes. A gutter clean-out is included with most roof cleaning jobs. Since debris from the roof ends up in the gutters during cleaning, we clear it all as part of our complete cleanup so your drainage works properly. If you're on a maintenance schedule, here's how often to clean your gutters.
Absolutely. We clean roofs on office buildings, retail spaces, warehouses, and multi-unit strata properties, and we coordinate directly with property managers and strata councils to schedule the work with minimal disruption.
If you're genuinely comfortable and safe working at height, you can. But it's risky — chemicals, ladders, and a real chance of a fall. One customer tried cleaning her own gutters after a bad experience with another company, fell, and broke her back; she now insists we handle it. For most people, it simply isn't worth the risk to your back or your roof.
