Victoria'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.
Metal roofs shed water well, but in Victoria’s damp, shaded conditions they still collect moss, algae and dark streaks — especially on north-facing slopes and under tree cover. Organic growth traps moisture against the panels and works into seams and fasteners.
Left untreated, that build-up can lead to corrosion around seams and fixings, staining that dulls the finish, and poor runoff. Regular low-pressure cleaning keeps the surface and its protective coating in good shape for decades.
Pressure washing and abrasive pads can scratch panels and strip the protective coating. We use gentle, roof-safe detergents and controlled low-pressure soft-washing that lift moss, algae and streaks from metal without ever damaging the surface.
Our Metal 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.
We clear all debris from the roof, gutters and surrounding area — and with most jobs a gutter clean-out is included. We leave the site spotless.
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 Victoria.
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.
A typical Victoria home, versus $15,000–$30,000+ for a full replacement.
Metal roof cleaning in Victoria starts at $600, and most homes land between $600 and $1,000, depending on roof size, pitch, and how much moss and staining has built up.

Metal roof cleaning starts at $600, and most Victoria homes land between $600 and $1,000. The exact price depends on roof size, pitch, height and how much moss or staining has built up — and it's a small fraction of the cost of premature roof repair. For a full breakdown, see our guide to roof cleaning costs in Victoria.
Only if it's done the wrong way. High pressure and abrasive tools can dent panels, scratch the finish and strip the protective coating. We use mild, roof-safe detergents and controlled low pressure, which is safe for metal and just as effective.
No. High-pressure washing can dent metal panels and force water under the seams and fasteners. We use gentle soft-wash solutions combined with careful hand-brushing — the safest, most effective method for metal. Using too much pressure is one of the most common mistakes we see with pressure washing in Victoria.
If moss or algae returns within 24 months of your metal roof cleaning, 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.
Bleach can remove moss but must be used with real caution on metal — the wrong mix can corrode panels and damage the finish. We use products designed specifically for roofs, so the surface and its coating stay protected.
Absolutely. We clean metal roofs on homes, 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.
