Why It Matters

Moss Isn't Just Ugly — It's Damaging Your Roof

Most Melbourne homeowners treat moss on their roof as a cosmetic issue. It's far more serious. Left untreated, moss and lichen cause progressive, expensive structural damage — damage that often isn't visible until it's already significant.

Melbourne's wet winters create ideal conditions for moss and lichen growth. Once established, biological growth spreads rapidly and works its way beneath tile surfaces, into ridge cap mortar and into seams on metal roofing.

Moisture RetentionMoss acts like a sponge, holding moisture against your roof surface for weeks after rain. Prolonged moisture contact degrades tile glaze and accelerates mortar erosion.
Tile & Mortar DamageLichen attaches to tile surfaces with root-like structures called rhizines that physically crack and lift tile glazing. This creates entry points for water and dramatically shortens tile life.
Blocked Gutters & DrainsMoss fragments break off and wash into gutters and downpipes during rain, causing blockages that lead to overflow, fascia damage and water pooling around your foundations.

Our Method

Biological Root Treatment

Scraping or pressure washing alone removes visible moss but leaves the root system — called rhizoids — embedded in the tile or mortar. Within weeks, the moss regrows from the same roothold. Our biological treatment eliminates the entire organism, root and all, so there's nothing left to regrow from.

01
Roof Inspection & AssessmentWe assess moss and lichen coverage, identify high-growth areas, check ridge caps and valleys, and select the appropriate biocide concentration for your roof type and infestation level.
02
Biocide ApplicationEPA-approved biological treatment applied across the full roof surface. The biocide penetrates below the moss to kill roots, spores and lichen rhizines — stopping regrowth at the source.
03
Removal & Surface CleanOnce the biological treatment has neutralised all growth, dead moss is carefully removed from the roof surface, valleys and gutters, leaving the surface clean and free of debris.
04
Prevention CoatingA protective inhibitor coating is applied to the cleaned surface, creating a barrier that prevents moss and algae spores from establishing for up to 12 months.

Stop It Coming Back

12-Month Prevention Coating

Treatment removes the moss. Prevention stops it returning. Our inhibitor coating is the most cost-effective way to maintain a moss-free roof year-round in Melbourne's damp climate.

01

Proven Inhibitor Formula

Our prevention coating uses a proven biostatic formula that prevents moss, algae and lichen spores from germinating on the treated surface. Applied after every moss removal treatment as standard.

02

12-Month Effective Period

The coating remains active for up to 12 months under normal Melbourne weather conditions. Annual reapplication keeps your roof protected year-round without repeated full treatment costs.

03

Safe for All Surfaces

EPA-approved and safe for use on terracotta, concrete tiles, Colorbond and metal roofing. Biodegradable and harmless to gardens, pets and rainwater once dry — typically within 2 hours.

Real Reviews

What Our Customers Say

I tried two other companies who just pressure washed the moss off. It came back within two months both times. Golden Star explained the root treatment approach — a full year later and my roof is still completely clear.

Peter L.Hawthorn, Melbourne

Heavy lichen across almost all our terracotta tiles. The team was knowledgeable, careful, and the result is incredible. They even found two cracked ridge caps during the inspection and fixed them on the spot.

KM
Karen M.Camberwell, Melbourne

Very impressed. They took the time to explain exactly why the moss kept coming back and what the biological treatment does differently. Roof has been clean for 14 months now. Worth every cent.

Questions & Answers

Moss Removal FAQ

Pressure washing removes the visible moss but leaves the root system — called rhizoids — embedded in the tile surface and mortar. Once the surface dries, moss regrows rapidly from the same roothold, often within 6–8 weeks. Our biological treatment kills the entire organism including roots and spores, so there's nothing left to regrow from.
Yes. We use only EPA-approved, biodegradable biocides that are safe for people, pets, plants and waterways once diluted and dry — typically within 2 hours. We protect garden beds near roof runoff areas before applying any products. We recommend disconnecting your rainwater tank inlet on the day of treatment as a precaution.
Moss is a soft, green plant-like growth that sits on the tile surface and holds moisture. It's relatively easy to treat. Lichen is a composite organism — part fungus, part algae — that attaches to surfaces using root-like structures called rhizines that physically penetrate and crack tile glaze. Lichen is harder to remove and causes more tile damage.
The biocide begins working immediately after application, killing growth within hours. We allow adequate dwell time before removal — the full process takes 3–6 hours depending on roof size and moss coverage. The prevention coating activates immediately on drying. Results are visible on the day, with the roof reaching its cleanest appearance within 48 hours.
With our biological treatment and 12-month prevention coating, most Melbourne roofs need treatment once per year. Heavily shaded roofs or those in high-moisture areas may benefit from a prevention coating reapplication at the 6-month mark. Our condition report includes a recommended maintenance schedule specific to your roof's situation.
