What We Do

Professional Metal Roof Cleaning

Melbourne's metal roofs — whether Colorbond, corrugated iron or tin — are engineered to last decades, but only when properly maintained. Dirt, algae, mould, lichen and debris accumulate over time, degrading the protective coating and accelerating rust and corrosion beneath.

Golden Star uses coating-safe cleaning methods specifically designed for metal roofing. We match pressure, temperature and pH-neutral detergents to your exact roof type, cleaning thoroughly without stripping the protective layer or invalidating manufacturer warranties.

Roof Types

All Metal Roof Types Cleaned

Colorbond, corrugated iron or tin — we use the right technique for every metal roof type found on Melbourne homes and commercial buildings.

Most Common

Colorbond Roofs

Colorbond is the most popular metal roofing in Melbourne. Its factory-applied Thermatech coating reflects heat and protects against corrosion — but that coating can be damaged by incorrect cleaning. We use low-pressure washing with pH-neutral detergents approved for use on Colorbond, preserving colour and coating integrity. Regular cleaning extends Colorbond life well beyond its standard warranty period.

Heritage Homes

Corrugated Iron Roofs

Corrugated iron roofs are common on Melbourne's older homes and heritage properties. Without a factory coating, they are more susceptible to surface rust and oxidation. We clean corrugated iron with controlled pressure and rust-inhibiting treatments, removing dirt and organic growth while addressing early-stage rust spots before they penetrate the metal. Painting recommendations are provided where needed.

Industrial & Sheds

Tin & Zincalume Roofs

Tin and Zincalume roofs are frequently found on sheds, garages, commercial buildings and rural properties. Algae, lichen and debris build up rapidly on these surfaces, and oxidation staining is common in Melbourne's coastal and suburban environments. We clean these roofs thoroughly using appropriate detergents and pressure settings, and apply rust inhibitor treatments where active corrosion is identified.

Why It Matters

Protecting Your Roof's Coating

The single biggest risk with metal roof cleaning is using the wrong pressure or chemicals — stripping the protective coating that guards against rust, fading and UV damage. Our approach is built around protecting that coating while still achieving a thorough clean.

Low-Pressure Soft WashWe use low-pressure washing combined with biodegradable detergents that break down organic growth without physically abrading the coating surface.
pH-Neutral Detergents OnlyAcidic or alkaline cleaners strip metal coatings. All our products are pH-neutral and specifically formulated to be safe on Colorbond and coated metal surfaces.
Rust Spot Identification & TreatmentDuring every clean we identify active rust spots and treat them on the day. Catching rust early prevents it spreading beneath the coating — a repair that can cost thousands if left untreated.
Warranty-Safe CleaningOur method follows manufacturer guidelines for Colorbond and coated metal roofs — so your warranty remains valid after every clean we perform.

Real Reviews

What Our Customers Say

Our Colorbond roof looks brand new. I was worried about the coating being damaged but they clearly knew exactly what they were doing. Used the right products and right pressure. Brilliant result.

Had a corrugated iron roof on my 1950s home that had rust patches developing. Golden Star cleaned it and treated every rust spot. Got a full report with photos afterwards. Very thorough and professional.

Booked the roof and gutter bundle — great value. The team was on time, tidy and finished ahead of schedule. Roof looked fantastic. Highly recommend for any Colorbond roof in Melbourne.

Questions & Answers

Metal Roof Cleaning FAQ

No — not when cleaned correctly. Colorbond warranties actually require regular cleaning to remain valid. The key is using the right products and pressure. We use only pH-neutral detergents at low pressure, following BlueScope's own maintenance guidelines. Incorrect cleaning using high pressure or harsh chemicals can void the warranty — which is exactly why professional cleaning matters.
BlueScope recommends cleaning Colorbond roofs every 6–12 months in coastal or industrial areas, and at least every 12 months in suburban Melbourne. Corrugated iron and uncoated metal roofs benefit from annual cleaning, particularly in areas prone to moisture, organic growth or airborne pollution.
Yes — surface and early-stage rust can be treated during the cleaning process. We apply rust inhibitor to affected areas, which stops oxidation from spreading and buys significant time before repainting becomes necessary. Deeply penetrated rust holes require patch or sheet replacement, which we can advise on and quote separately during the inspection.
Colorbond has a multi-layer factory finish that must be preserved — it requires very low pressure and pH-neutral cleaning products. Corrugated iron typically has no factory coating, so slightly more pressure can be used, but rust treatment becomes more important. We adjust our approach based on which metal type we're cleaning.
Yes. We clean metal roofs on warehouses, factories, industrial buildings and commercial properties across Melbourne. We carry full public liability insurance, provide SWMS documentation, and can schedule after hours to avoid business disruption. Visit our commercial roof cleaning page for full details.
