Thinking about switching from a tiled roof to a metal one? You’re not alone. Many Aussie homeowners are making the change, especially when their old tiles start showing signs of wear or they’re looking to modernise their property. But re-roofing isn’t just a matter of swapping materials; it involves careful planning, structural assessments, and budgeting.
Why Make the Switch to Metal Roofing
Metal roofing, especially Colorbond®, is becoming a go-to option across Australia, and for good reason:
- Lightweight yet durable – Metal sheets are significantly lighter than tiles, which reduces stress on your roof frame.
- Low maintenance – Unlike tiles, metal roofing doesn’t crack or shift over time.
- Modern look – Clean lines and a range of colours make metal roofs perfect for contemporary designs.
- Weather resistance – Colorbond and similar products are designed to handle Australia’s tough climate, from coastal storms to outback heat.
- Bushfire protection – Metal roofs can offer better protection in high BAL (Bushfire Attack Level) zones.
The Re-Roofing Process: Step by Step
Switching from tiles to metal involves more than just removing one roof and laying another. Here’s how the process usually works:
Inspection & Quote
- A licensed roofer like Ocean Blue will inspect your existing roof and structure
- You’ll get a detailed quote covering materials, labour, and any necessary repairs.
Structural Assessment
- Since metal roofing is lighter than tiles, the roof frame is usually strong enough, but it still needs to be checked for any signs of rot, termite damage or movement.
Removal of Old Tiles
- Tiles and battens are removed carefully to avoid damage to the structure underneath.
- This stage also gives an opportunity to upgrade insulation or install sarking (a reflective foil layer).
Roof Frame Adjustments
- Any structural reinforcements or repairs are done at this stage.
- New battens suitable for metal sheeting are installed.
Laying the Metal Roofing
- Sheets are cut and fixed into place, ensuring proper overlap and sealing.
- Ridge capping, flashings and gutter connections are installed for a clean, watertight finish.
Final Checks & Clean-Up
- The site is cleaned up, old tiles are disposed of responsibly, and a final inspection ensures everything’s up to standard.
How Much Does It Cost to Replace Tiles with Metal Roofing?
Costs can vary depending on your roof size, pitch, and complexity. On average, Australians can expect:
- Removal of tiles: $30–$50 per square metre
- New Colorbond roofing: $50–$80 per square metre
- Total project cost: Around $12,000–$25,000 for an average home
Keep in mind that prices may also include insulation upgrades, structural repairs, and disposal of old materials. While it’s a decent investment upfront, the long-term savings on maintenance and energy bills make it worthwhile for many homeowners.
Planning Permission and Compliance
In most areas, switching roof materials doesn’t require full planning approval, but you should still check with your local council, especially if you’re in a heritage-listed zone. At Ocean Blue, we handle all relevant compliance and safety measures to ensure a smooth process.
Is It Worth Replacing Your Tiled Roof with Metal?
If you’re dealing with cracked or slipping tiles, poor insulation, or just want a modern look with less upkeep, metal roofing is a smart long-term upgrade. With better weather resistance, bushfire safety, and aesthetic appeal, it can boost both your comfort and your property’s value.
