Tile Roof Restoration vs Metal Roof Restoration: What's the Difference? (2026)

Brisbane and the Gold Coast have a huge mix of roof types. Older homes with terracotta or concrete tiles, newer builds with Colorbond or corrugated iron, and plenty of properties that combine both. If you are considering a restoration, it is worth understanding how the process differs between tile and metal, because the preparation, repairs and coating systems involved are quite different.

Quick answer: Both tile and metal roofs can be restored, but the process differs. Tile restorations focus on structural repairs such as repointing and rebedding before coating. Metal restorations prioritise rust treatment and fastener replacement. Costs are broadly similar, but tile roofs typically require more labour.

Tile Roof Restoration: What's Involved?

Tile roofs, whether concrete or terracotta, are the most common roof type on established homes across Brisbane and the Gold Coast. Over time, tiles fade, crack, and the mortar that beds and points the ridge caps deteriorates. This allows water to enter the roof cavity. See real tile restoration projects in our Our Work section, including jobs in Victoria Point, Forest Lake and Coomera.

The Tile Restoration Process

• High-pressure cleaning to remove moss, lichen, dirt and old deteriorated coating

• Inspection to identify cracked, broken or slipped tiles

• Replacement of damaged tiles with matching or compatible alternatives

• Ridge cap rebedding, which involves removing old failed mortar and relaying ridge caps properly

• Flexible repointing compound applied over rebedded ridge caps

• Anti-fungal and mould treatment

• Primer coat applied to the cleaned and prepared surface

• Two coats of high-performance membrane coating

The rebedding and repointing stage is what separates a proper tile restoration from a cheap repaint job. Without it, even a freshly coated tile roof will continue to allow water entry at the ridgeline.

Common Issues Found on Brisbane Tile Roofs

• Cracked or hairline fractured tiles, often caused by thermal expansion and storm activity

• Hollow or loose ridge caps where mortar fails after years of heat cycling

• Biological growth, as moss and lichen thrive in Brisbane's humidity and retain moisture against tiles

• Faded or chalking coating from UV breakdown of older coatings

• Slipped tiles from movement along the ridgeline, particularly on older battens

Metal Roof Restoration: What's Involved?

Metal roofs including Colorbond, corrugated iron and zincalume are common on both older Queensland homes and newer builds. They are durable but not maintenance-free. Over time, metal roofs suffer surface oxidation, rust, loose or corroded screws and UV-driven paint breakdown. See a completed metal roof restoration from our portfolio: Full Roof Restoration - Willow Vale (Metal, Shale Grey).

The Metal Restoration Process

• High-pressure cleaning to remove surface contamination, oxidation and loose material

• Rust treatment applied to any corroded areas

• Replacement of worn or corroded screws with new sealed fasteners

• Sealing of any laps, joints or penetrations where water can enter

• Application of a flexible primer suited to metal surfaces

• Two coats of UV-resistant protective coating designed for metal

The key difference with metal is flexibility. Metal expands and contracts significantly with Queensland's temperature swings. The coating system needs to flex with the roof rather than crack under movement, which is why standard tile coatings are not appropriate for metal surfaces.

Common Issues Found on Brisbane Metal Roofs

• Surface rust and oxidation, particularly around screw heads and laps

• Loose or missing screws, which are the most common cause of leaks on metal roofs

• Dented or damaged sheets from hail or falling debris

• Faded paint, as Colorbond's factory finish degrades under sustained UV exposure

• Corrosion at laps and penetrations

Cost Comparison: Tile vs Metal Restoration

Both roof types fall within a similar overall price range for a standard Brisbane or Gold Coast home. However there are some differences worth knowing.

• Tile roofs tend to cost slightly more due to the additional labour involved in rebedding and repointing. Individual tile replacement also adds to the cost if there is significant breakage. For accurate pricing, see our roof restoration cost guide.

• Metal roofs often require less structural repair work but may need more preparation to address rust and corrosion. Screw replacement across a full roof adds labour time. Request a free inspection here.

Which Lasts Longer: Tile or Metal?

Both roof types, when properly restored, offer excellent long-term performance.

• Concrete and terracotta tiles can last 50 years or more when well maintained. A quality restoration with a proper 3-coat system adds another 15 to 20 years of protection. See our Warranty page for full details.

• Metal roofs typically last 20 to 40 years depending on the material and environment. Coastal homes in areas like the Gold Coast can experience accelerated corrosion from salt air, making regular maintenance particularly important.
  

Which Roof Type Is More Common in Your Area?

In our experience working across Brisbane and the Gold Coast:

• Inner Brisbane suburbs like New Farm, Bulimba and Ashgrove tend to have older terracotta tile roofs on character homes from the 1950s to 1980s.

• South-east Brisbane and Logan suburbs like Springwood and Daisy Hill have a higher proportion of concrete tile roofs from the 1980s to 2000s.

• Gold Coast suburbs like Southport, Burleigh Heads and Coomera have a mix of tile and metal roofs, with newer estates more likely to feature Colorbond.

Frequently Asked Questions

Can you restore a roof that has both tile and metal sections?

Yes. Some homes have a mix, typically a tiled main roof with a corrugated iron section over a patio or extension. Each section is treated with the appropriate process and coating system for its material.

Does the coating look different on tile vs metal?

The finished appearance can be quite similar, with both achieving an even, clean finish. Tile roofs have more texture from the tile profile. Metal roofs have a smoother, more uniform appearance. Both can be coated in a wide range of colours.

My roof has some tiles and some Colorbond. Who do I call?

Roof Werx handles both. We assess mixed roofs during the inspection stage and apply the appropriate system to each section. Get in touch for a free quote.
