Cost to install Colorbond Roof

The average cost to replace a metal roof in Melbourne typically ranges from $125 to $250 per square metre for fully installed materials and labour. For a standard three-bedroom house, clients can generally expect a total project cost between $20,000 and $30,000. Two storey houses are more expensive due to safe access costs and houses with steep roof are generally more expensive than flat roofs. Commercial properties and shops vary more as they often include box gutter systems that require expensive modification to meet modern standards as well as the safety issues related to more open span structures, all these are simple to overcome they just require more time and expense.

Replacing your roof is a major investment that protects your property, improves thermal efficiency, and increases market value. Because every property in Melbourne is structurally unique, we price our projects based on many factors such as roof area, complexity of building design, access from adjacent streets and laneways, many flat roof building in Melbourne were constructed with roofs below the minimum roof pitch of 1 degree and need additional work to rectify this. we assess all factors when quoting your project. This ensures you only pay for the exact materials and labour your building requires. 

No two roofing quotes are identical because on-site conditions vary. When we visit your property for a comprehensive site assessment, the final price is determined by five major variables

• Existing Roof Type: Swapping an old metal roof for a new one is highly cost-effective. Converting an old concrete or terracotta tile roof to metal requires installing new timber battens and structural adjustments, which adds to the overall labour costs.
• Roof Pitch & Complexity: Flat or low-pitch skillion roofs are faster and safer to work on. Steeply pitched roofs, complex valleys, multi-storey designs, or buildings with frequent skylights require advanced safety setups and take longer to complete.
• Site Access & Safety: In tightly packed Melbourne suburbs, narrow side pathways or zero-lot lines require specialized crane hires, material lifting gear, or heavy-duty scaffolding to comply with WorkSafe Victoria regulations.
• Upgraded Insulation & Drainage: A roof replacement is the most cost-effective time to introduce thick insulation blankets or update old, rusted gutters and downpipes to modern systems.
