When it comes to roofing, most homeowners in Melbourne, Australia are familiar with tiles, shingles, or metal sheets. But one critical—yet often overlooked—component is roof lining, also referred to as sarking or roof insulation. Lining a roof plays a key role in protecting your home from moisture, heat, and pests, and it significantly enhances thermal performance and energy efficiency.

So, how much does it cost to line a roof in Melbourne? The short answer is: anywhere between $8 to $40 per square metre, depending on various factors like material choice, roof accessibility, and labor complexity. But the real answer? That’s what we’ll unpack below—with detailed insights, local market references, and cost breakdowns to help you make a smart investment in your roofing system. Let’s get into details with Gutter Cleaning Melbourne.
✅ What Is Roof Lining?
Roof lining is a protective layer installed beneath roof coverings such as tiles or metal sheets. Its main functions include:
- Preventing water ingress during heavy rains or wind-driven weather
- Improving insulation and reducing heat transfer
- Blocking dust and debris
- Acting as a secondary barrier against bushfire embers—a crucial feature in many parts of Victoria, especially in outer-Melbourne suburbs like Lilydale, Dandenong Ranges, and Sunbury
Common materials used include:
- Foil sarking (reflective insulation)
- Breathable membranes (vapour-permeable sarking)
- Bituminous felt (more common in older structures)
- Polyester batts or rolls
📍 Average Roof Lining Costs in Melbourne (2025 Update)
Roof lining costs can vary based on size, pitch, and roof structure. Here’s a quick breakdown of Melbourne roofing prices:
Material Type | Average Cost (per m²) | Labour Cost (per hour) | Estimated Total (100m² roof) |
---|---|---|---|
Foil-backed sarking | $8 – $12 | $60 – $90 | $1,300 – $2,000 |
Breathable membrane | $12 – $20 | $70 – $100 | $1,800 – $2,700 |
Insulated roof lining system | $25 – $40 | $80 – $120 | $3,300 – $5,500 |
Note: These prices are typical of Melbourne’s inner and outer suburbs, including areas like Coburg, Glen Waverley, and Frankston. High-end suburbs such as Toorak or Brighton may attract slightly higher rates due to access and compliance factors.
🏗️ What Affects the Cost of Roof Lining?
- Roof Size & Complexity
- The bigger and steeper the roof, the more material and time needed.
- Multi-gabled or heritage-style homes in Carlton or Fitzroy may require more precision and scaffolding.
- Material Type
- Foil sarking is the most cost-effective, but doesn’t offer breathability.
- Vapour-permeable membranes, ideal for Melbourne’s varying humidity levels, are pricier but allow moisture to escape.
- Labour Rates
- Labour costs in Melbourne typically range between $60–$120/hour, depending on the roofer’s experience and location.
- Roof Accessibility
- Homes with restricted access (e.g., inner-city townhouses) may incur additional costs for scaffolding or edge protection.
- New Installation vs Retrofit
- Installing roof lining during a roof replacement is cheaper than retrofitting, which involves lifting existing materials and resealing them.
🧰 Is It Worth Investing in Roof Lining?
Absolutely. Here’s why Melbourne homeowners are choosing to invest:
- Energy Efficiency: A lined roof helps keep your house cooler in summer and warmer in winter—essential in Melbourne’s famously erratic climate. This reduces air conditioning costs by up to 20% annually.
- Moisture Protection: Roof lining helps prevent mould growth, timber rot, and condensation damage—common problems in humid bayside areas like St Kilda and Elwood.
- Fire Safety Compliance: For homes in bushfire-prone zones (e.g., Healesville, Eltham, Warrandyte), installing AS 3959-compliant roof sarking is not just smart—it’s mandatory.

🛠️ DIY vs Professional Installation
If you’re wondering whether you can DIY this—proceed with caution. While it’s technically possible for skilled homeowners to install basic sarking under new sheets, roof work is inherently risky, especially at heights.
💡 In Victoria, roofing work that exceeds $10,000 requires a licensed builder under the Building Act 1993. Improper installation can void your warranty or violate building codes.
