Metal roofing in Australia costs between $20,000 to $40,000 for an average home, with prices typically ranging from $60 to $100 per square metre installed. This cost varies widely based on several key factors including the specific metal type, roof complexity, accessibility, and current material prices.
The metal roofing market offers different price points depending on your choice of material. Zincalume is generally the most affordable option at $60-$75 per square metre, while Colorbond costs $70-$90 per square metre. Premium metals like copper or zinc can push prices well above $200 per square metre.
Roof size and complexity directly influence your bottom line. A simple gabled roof will cost substantially less than a complex roof with multiple pitches, valleys, and penetrations. Each extra detail requires additional materials and labour time, increasing your overall investment.
New installations versus roof replacements present different cost structures. A brand new metal roof installation on a standard Australian home typically starts around $20,000. Roof replacements cost approximately 15-30% more (about $3,000-$12,000 extra) as they involve removal and disposal of existing materials, potential structural repairs, and sometimes additional waterproofing measures.
What is Metal Roofing?
Metal roofing is a premium roofing system composed of metal sheets or tiles that interlock to form a durable, weather-resistant surface above your home. These systems typically last 40-70 years, with some premium options potentially lasting even longer when properly maintained.
Metal roofing differs significantly from traditional roofing materials like concrete or terracotta tiles. The metal sheets are lighter, placing less structural stress on your home's frame. They're also more resilient against harsh Australian weather conditions, offering superior protection against bushfires, extreme heat, and severe storms. Additionally, metal roofs reflect solar radiation rather than absorbing it, improving your home's energy efficiency and potentially reducing cooling costs during hot Adelaide summers.
The Australian metal roofing market features several common options. Colorbond steel is perhaps the most popular choice, offering excellent durability with a wide range of colour options to match any home style. Zincalume provides outstanding corrosion resistance with its aluminium-zinc alloy coating. Standard steel with various protective coatings offers versatility at different price points. Copper, while more expensive, delivers unmatched longevity and develops a distinctive patina over time that many homeowners find attractive.
What are the factors affecting Metal roofing cost?
Main cost factors in metal roofing include material type, roof size (m²), shape, pitch, labour cost, and region. Each of these elements significantly impacts your final price tag in different ways.
The material type is perhaps the most influential factor. Premium metals like copper can cost three times more than standard steel options. Each material offers different benefits, from enhanced corrosion resistance to superior longevity, with prices reflecting these advantages.
Your roof size directly correlates with cost - larger roofs require more materials and labour hours. Australian roofers typically measure in square metres, with most residential roofs ranging between 160-250m². This measurement forms the foundation of your quote.
Roof shape and pitch (steepness) dramatically affect installation difficulty. Complex designs with multiple angles, valleys, ridges, and penetrations require more cutting, custom flashings, and careful water management solutions. Steeper pitches also demand additional safety equipment and slow down the installation process, increasing labour costs.
Labour rates vary significantly across Australia, with metropolitan areas like Sydney and Melbourne typically charging 15-30% more than regional areas. Experienced metal roofing specialists command higher rates but often deliver superior workmanship.
Potential additional fees include underlayment costs ($10-$20 per m²), which provide an extra moisture barrier beneath your metal roofing. The removal and disposal of your old roof can add $30-$80 per m² to your project, depending on material type and local disposal regulations.
Cost of Installing metal roofing by Type
Colorbond steel roofing costs between $70-$90 per m² installed, making it a mid-range option that balances quality and affordability. This Australian-made product comes in 22 designer colours and includes a 30-year warranty against peeling and cracking.
Corrugated steel roofing ranges from $65-$80 per m² installed. This traditional profile offers excellent water shedding capabilities and a classic Australian aesthetic. Its simplified design makes it one of the more economical metal roofing options.
Zincalume steel roofing typically costs $60-$75 per m² installed. This aluminium-zinc alloy coating provides up to four times the lifespan of conventional galvanised steel, offering excellent value over time. Zincalume is particularly suitable for coastal areas due to its superior corrosion resistance.
Copper roofing represents the premium end of the market at $200-$300+ per m² installed. While substantially more expensive initially, copper offers unmatched longevity (potentially 100+ years), develops a distinctive patina, and requires minimal maintenance. This prestigious material is often selected for heritage buildings or architectural statement pieces.
How Much Does Colorbond Roofing Cost?
Colorbond roofing materials alone cost between $25-$40 per m² depending on the specific profile and thickness selected. The total installed cost typically ranges from $70-$90 per m² when including professional labour, fixings, flashings, and other installation necessities.
A properly installed Colorbond roof has an impressive lifetime expectancy of 30-50 years, making it one of the most durable roofing options in the Australian market. This longevity is backed by manufacturer warranties of up to 30 years, providing additional peace of mind for homeowners.
Several factors influence the final cost of your Colorbond roofing project. The colour selection impacts pricing, with standard colours typically costing less than premium or custom shades. Colorbond offers five product ranges (Classic, Contemporary, Matt, Ultra, and Metallic) with varying price points. The Ultra range, designed specifically for severe coastal environments, and the Metallic range with its distinctive appearance, command higher prices than the standard Classic range. Thickness grades also affect pricing, with the heavier commercial grades costing more than residential options.
How Much Does Corrugated Steel Roofing Cost?
Corrugated steel roofing materials typically cost between $20-$30 per m² for standard grades. The total installed cost ranges from $65-$80 per m² including professional labour, fixings, and all necessary components for a complete roofing system.
A quality corrugated steel roof has a lifetime expectancy of 25-40 years when properly installed and maintained. This lifespan varies based on the specific coating quality, local climate conditions, and maintenance regimen.
The final cost of corrugated steel roofing is influenced by several important factors. Base metal thickness significantly impacts both price and durability, with commercial grades costing more than residential options. Coating type is another important factor - galvanised coatings are more affordable but offer less corrosion protection than premium finishes. Colour options also affect pricing, with standard colours generally more economical than custom shades. Additionally, the profile depth (how "wavy" the corrugation is) influences both material requirements and installation complexity, with deeper profiles typically commanding higher prices but offering superior water-shedding capabilities.
How Much Does Zincalume Roofing Cost?
Zincalume roofing materials alone cost between $20-$30 per m² for standard panels. The total installed cost typically ranges from $60-$75 per m² when including professional labour, fasteners, flashings, and other installation components.
A properly installed Zincalume roof offers an impressive lifetime expectancy of 30-40 years in most Australian environments. This longevity is supported by manufacturer warranties typically ranging from 20-25 years against perforation due to weathering.
Several factors influence the final cost of your Zincalume roofing project. Sheet thickness (measured in millimetres) directly impacts both price and durability, with thicker sheets commanding higher prices but offering enhanced structural integrity. Profile selection affects both material requirements and installation complexity, with more complex profiles typically costing more than simple corrugated designs. While Zincalume naturally comes in a silver-grey finish, painted Zincalume options are available at higher price points. Additionally, the roof's complexity, including the number of penetrations, valleys, and flashings required, can significantly increase material needs and labour time, affecting your final investment.
How Much Does Copper Roofing Cost?
Copper roofing materials alone cost between $150-$200 per m² for standard sheets, representing the premium end of metal roofing options. The total installed cost typically ranges from $200-$300+ per m² when including professional labour, specialised fixings, and custom fabrication work often required with this luxury material.
A properly installed copper roof boasts an exceptional lifetime expectancy of 70-100+ years, making it potentially the longest-lasting metal roofing option available in Australia. This extraordinary longevity helps offset the higher initial investment over the roof's lifespan.
The final cost of copper roofing is influenced by several significant factors. Copper thickness (measured in ounces per square foot or millimetres) directly impacts pricing, with thicker sheets offering enhanced durability at higher costs. Installation style dramatically affects both material requirements and labour complexity—standing seam installations typically cost more than simpler copper panel systems. Copper naturally develops a distinctive patina over time, changing from its initial bright penny appearance to eventually forming its characteristic green patina in 15-20 years. Some homeowners prefer pre-patinated copper (chemically treated to speed up this natural weathering process), which commands a premium price. Additionally, the complexity of roof details, including ornamental elements often incorporated with this premium material, can substantially increase both material and labour costs.
How to choose the best metal roofing type to Install?
Selecting the right metal roofing for your home involves balancing several important factors. Here's how to determine which option best suits your needs:
Consider your budget constraints first. Metal roofing options vary widely in price, from relatively affordable Zincalume at $60-$75 per m² installed to premium copper at $200-$300+ per m². Establish your maximum budget before exploring options to avoid disappointment.
Evaluate the expected longevity against your long-term plans. If you're planning to stay in your home for decades, investing in longer-lasting materials like Colorbond (30-50 years) or copper (70-100+ years) makes financial sense despite higher upfront costs. For shorter-term solutions, standard corrugated steel (25-40 years) might offer better value.
Assess your local climate conditions carefully. Coastal homes face accelerated corrosion from salt spray, making marine-grade Colorbond Ultra or Zincalume better choices than standard steel. Bushfire-prone areas benefit from metal roofing's superior fire resistance. Areas with high rainfall need roofing with excellent water-shedding properties like well-designed corrugated profiles.
Consider maintenance requirements that match your lifestyle. Copper develops a natural patina requiring minimal intervention. Colorbond needs only occasional washing to maintain its appearance. Standard galvanised steel might require more frequent inspections and potential recoating to prevent rust in challenging environments.
Evaluate your home's architectural style for aesthetic compatibility. Certain profiles and finishes complement specific home designs better than others. Traditional homes often pair well with classic corrugated patterns, while contemporary designs might benefit from the clean lines of standing seam systems.
