First Class Roofing installs, restores and repairs galvanised roofing across Melbourne — backed by over 25 years of hands-on experience across metropolitan Melbourne. Whether your property needs new corrugated roofing sheets, a full galvanised steel roof replacement, or repairs to an existing metal roof, we’ll inspect your roof thoroughly and recommend the option that genuinely suits the building.
We work across Melbourne’s inner northern suburbs — including Carlton, Brunswick, Fitzroy, Collingwood and Northcote — as well as inner-city terrace houses, heritage properties, commercial buildings and industrial sites. Call us on 0412 069 632 or use the Get A Free Quote form to arrange your quote.
Our team understands how Melbourne’s climate affects galvanised steel over time — thermal movement, moisture and the way older sheets behave once their coating has aged — and we’ll explain every option so you can make a confident, informed decision about your roof.
Galvanised roofing is a long-term investment, and the quality of the installation determines how long that investment lasts. Small errors in sheet alignment, incorrect fastener placement or the wrong coating specification can lead to premature corrosion, leaks and structural damage. With over 25 years of roofing experience behind every job we take on, we diagnose problems correctly the first time — which avoids unnecessary work and repeat repair bills.
Michael Lanyon leads assessments personally on galvanised and corrugated metal roofing across residential, commercial and heritage properties throughout Melbourne. That depth of practical knowledge means your roof is assessed honestly — not oversold. If a repair is the right answer, we’ll say so. If a full replacement with quality galvanised steel sheets is the better long-term solution, we’ll explain exactly why.
Our tradespeople are qualified and licensed Roof Plumbers and Roof Tilers. They arrive on time, communicate clearly, work to a high standard and leave your site clean and tidy at the end of every day. Every job is covered by our 10 year guarantee on workmanship, and where the work is plumbing-regulated, a Compliance Certificate is issued by the Plumbing Board.
Roofing decisions shouldn’t feel stressful. We’ll walk you through your options across galvanised corrugated sheets, Colorbond and other metal roofing, then put it in writing as a detailed, itemised quote — so the price you agree to is the price you pay. We serve Melbourne’s inner northern suburbs and inner-city areas, including Brunswick, Carlton, Fitzroy and Northcote.

We offer a complete range of galvanised roofing services for Melbourne homeowners, property managers and commercial clients. From new corrugated roofing sheet installations on residential properties to large-scale galvanised steel roof replacements on commercial and industrial sites, we tailor every solution to the property’s roof profile, exposure and long-term protection requirements.
Galvanised corrugated roofing sheets remain one of the most widely used roofing materials across Melbourne’s residential and commercial properties — and for good reason. The corrugated profile adds structural rigidity to relatively thin galvanised steel, allowing sheets to span across purlins without additional support. Each sheet is formed from cold-rolled steel and coated in zinc, which forms a durable barrier against corrosion.
We supply and install galvanised corrugated iron roofing sheets across Melbourne’s inner northern suburbs, inner-city properties and surrounding metropolitan areas. Sheets come in a range of lengths, and we cut to the length required for a precise, professional fit. Whether you’re replacing an ageing corrugated iron roof or roofing a residential extension or outbuilding, we’ll recommend the right gauge, coating weight and profile for the application.
The table below outlines common galvanised roofing applications and the selection considerations that matter most.
| Application | Recommended Material | Key Consideration |
| Residential home roof replacement | Galvanised steel or Colorbond corrugated sheets | Profile, colour and coating weight suited to the roof’s pitch and exposure |
| Heritage terrace or Victorian-era home | Corrugated galvanised iron, profile-matched | Preserving the original corrugated profile for heritage compliance |
| Shed, garage or outbuilding | Standard corrugated galvanised roofing sheets | Cost effective zinc-coated steel for low-maintenance structures |
| Commercial or industrial facility | Galvanised steel or BlueScope corrugated sheets | Spanning length and corrosion class rating |
Galvanised steel roofing sheets get their corrosion resistance from a zinc coating applied during manufacturing. The steel substrate passes through molten zinc, which bonds metallurgically to the steel surface — producing a coating far more durable than paint alone. The zinc layer acts as a sacrificial barrier: even if the steel is scratched or cut, the surrounding zinc continues to protect the exposed steel through cathodic protection.
The weight of that zinc coating — specified in grams per square metre by the manufacturer — is one of the main factors in how the roof performs over time. Heavier coatings are specified for more demanding exposures. Melbourne’s climate, with its combination of summer heat, autumn rain and sharp temperature swings, places real demands on roofing materials, which is why correct specification matters from the outset.
It’s also worth knowing that galvanised steel performs best in sheltered, inland environments — which describes most of the inner-north Melbourne housing stock we work on. Where a property is genuinely exposed to salt-laden air, alternative coatings such as those used in BlueScope’s Zincalume® or Colorbond® ranges are usually the better specification. We’ll assess your property’s actual exposure and tell you honestly which material suits it.
One of the most common questions Melbourne homeowners ask is whether an ageing galvanised roof needs repairs, restoration or full replacement. The honest answer depends on the condition of the existing sheets, the extent of any corrosion, and your long-term plans for the property.
If your galvanised roof has isolated rust spots, minor leaks or loose sheets, targeted repairs are often enough to extend the roof’s working life without the cost of full replacement. We’ll inspect the affected areas, identify the root cause and repair it properly.
If the corrugated iron shows widespread surface corrosion, a worn zinc coating or recurring leaks across multiple areas, restoration work — rust treatment, sealing and protective coating — may be the cost effective option, depending on the sheet gauge and remaining metal thickness.
If the galvanised steel roofing sheets are heavily corroded, perforated or structurally compromised, replacement with new corrugated roofing sheets is the right long-term answer. Continuing to patch a roof that has reached the end of its service life costs more over time than a properly planned replacement.
You’ll get an honest assessment, and the reasoning behind every recommendation, so you can make the decision that’s right for your property and your budget.
Leaks, storm damage, rusting sheets and lifted corrugated iron are among the most common metal roofing problems we see across Melbourne properties. Left unaddressed, even a small roof leak can cause water damage to ceiling linings, insulation, timber framing and internal walls — repairs that quickly exceed the cost of fixing the roof itself. Water damage spreads, so it’s worth getting a leak looked at rather than waiting to see what happens.
We repair all types of galvanised and metal roofing — corrugated iron sheets, flat metal roofing, valley iron, ridge capping and flashings. We identify the source of the leak accurately rather than applying a surface fix that doesn’t last. Every metal roof repair is completed with quality materials and workmanship, and covered by our 10 year guarantee on workmanship.
Where galvanised roofing meets ridge capping, hip ends or abutments, the pointing and bedding compounds that seal these junctions deteriorate over time — particularly on older Melbourne homes where the original materials have taken decades of thermal movement and weather. Cracked or crumbling pointing lets water track beneath the capping and into the roof structure.
We regrout and repoint ridge capping, hip cappings and abutment flashings using flexible, weather-resistant compounds suited to Melbourne’s temperature range. Proper repointing protects the junction and prevents water ingress without the need for full sheet replacement.
Flat metal roofing is a common feature on Melbourne’s heritage terrace houses, Victorian-era homes and Edwardian properties — as well as on commercial buildings and industrial sites throughout the inner north and surrounding suburbs. We install, restore and repair flat metal roofing using galvanised steel and Colorbond materials appropriate to the structure and its exposure.
Flat metal roofs need particular attention to falls, drainage and sheet overlap to prevent pooling water, which accelerates corrosion in galvanised steel. We assess the fall and drainage of every flat metal roof we work on and address any issues as part of the installation or restoration.
We install and replace galvanised steel roofing on commercial and industrial properties across Melbourne. Commercial galvanised roofing requires precise specification of sheet gauge, spanning length and coating class to meet the corrosion requirements of the site.
For property managers and body corporates weighing up site access, the compliance detail matters as much as the roofing. We carry plumber’s insurance, public and product liability cover up to $20 million and WorkCover, and all our sites comply with WorkSafe Victoria requirements. Projects are managed with reliable scheduling, clear communication and minimal disruption to your operations.
Many older Melbourne properties — particularly those built before the 1980s — have asbestos-cement roofing, and on a galvanised job it is not unusual to find asbestos sheeting alongside or beneath the iron. Removing an asbestos roof and replacing it with a new Colorbond or galvanised corrugated roof is a service we provide.
This work is carried out in accordance with Australian health and safety standards, the Victorian Occupational Health and Safety Act and Environmental Protection Authority (EPA) requirements, and complies with WorkSafe Victoria and EPA guidelines. Our health and safety management system is Cm3 qualified. Our team holds Asbestos Awareness training (10314NAT), which is awareness-level training in identifying asbestos materials and working safely around them.
The work is carried out wearing full protective clothing, respirators and gloves. After removal, the area is thoroughly cleaned and vacuumed, and the asbestos material is disposed of in accordance with environmental regulations. An Asbestos Clearance Certificate is provided to the homeowner on completion.
Where the replacement roof is Colorbond steel, it carries a 20 year materials warranty from Bluescope Steel, alongside our 10 year guarantee on workmanship. If you have questions about occupancy or access to parts of the property while the work is under way, raise them at the on-site inspection — the answer depends on the building and the scope of the job.
Alongside galvanised roofing, our roofing solutions include:
