Headline cost difference (Adelaide, 2026)

On a typical 150sqm single-storey Adelaide home: Colorbond re-roof $15,000–$28,000; concrete tile re-roof $17,000–$28,000; terracotta tile re-roof $19,000–$32,000. The materials are closer in initial cost than the marketing suggests. The real cost difference is over the next 25 years.

Initial cost — Colorbond is slightly cheaper

Colorbond installs faster (sheets vs individual tiles) and disposes lighter (about a third the weight of tile). On a typical Adelaide roof, Colorbond is usually a little cheaper to install than a new tile roof — your itemised quote will show the difference for your home. The catch: structural reinforcement is sometimes needed when going FROM Colorbond TO tile (because tile is heavier); going from tile to Colorbond is straightforward.

25-year cost — Colorbond wins decisively

Tile roofs need ridge cap rebedding every 15–25 years ($2,400–$5,800), occasional broken tile replacement, and tile restoration painting at the 20-year mark ($4,500–$9,500). Over 25 years those costs add up. Colorbond, by contrast, needs very little maintenance — mainly washing down areas not cleaned by rain, more often near the coast, as BlueScope’s care guidelines recommend.

Weight and structure

Concrete tile: 40–60kg/sqm. Terracotta tile: 35–50kg/sqm. Colorbond: 5–8kg/sqm. Going FROM tile TO Colorbond is straightforward (the existing structure is over-spec’d). Going FROM Colorbond TO tile usually requires structural reinforcement of rafters and battens — adds $5,000–$15,000.

Thermal — closer than you think

The ‘tile is cooler’ folklore is partially outdated. Modern Colorbond with Thermatech heat-reflective coating, anticon insulation blanket, and ceiling insulation runs comparable to a tile roof. Light-coloured Colorbond (Surfmist, Shale Grey) is among the coolest roofing options. Dark Colorbond (Monument, Basalt) does run hot — that’s a real consideration for west-facing rooflines.

Acoustic — Colorbond is fine when properly installed

The ‘metal roof is loud in rain’ perception comes from 1980s un-insulated installs. Modern Colorbond with anticon blanket plus ceiling insulation is barely noisier than a tile roof. The acoustic difference is real but small.

Warranty — Colorbond wins

BlueScope offers warranties on COLORBOND® steel of up to 36 years for some products and roofing applications; the term that applies depends on the product, colour and site conditions (such as distance from the coast), and on installation and maintenance to BlueScope’s guidelines. Tile manufacturers offer long warranties on the tile body; on concrete tile the surface coating wears much sooner, while terracotta’s natural fired surface doesn’t need recoating. Check the warranty for the specific product quoted.

When tile still wins

Heritage character match (council overlay, historic 1920s look). Thermal mass is genuinely useful (large west-facing room, no air-con). You like the look and you’re prepared to budget for the maintenance cycle. Outside those cases, Colorbond usually has the better long-run economics.

Frequently asked

Is Colorbond or tile cheaper for a new roof in Adelaide? Up front they’re close: about $15,000–$28,000 for a single-storey Colorbond re-roof against $17,000–$28,000 for concrete tile and $19,000–$32,000 for terracotta. Over 25 years Colorbond usually costs less, because tile roofs need ridge cap rebedding, broken tile replacement and, for concrete tile, recoating.

How much does it cost to replace a tiled roof with Colorbond in Adelaide? A single-storey tile-to-Colorbond conversion typically costs $22,000–$45,000. The price covers stripping and disposing of the tiles, adapting the battens for metal sheeting, insulation blanket, new sheets, ridge capping, flashings and usually new gutters. Asbestos found during the strip is quoted separately.

Can you change a tile roof to metal on an Adelaide home? Yes. Going from tile to Colorbond is straightforward structurally, because metal is much lighter than tile. Heritage-listed homes and properties in historic or character overlays may need planning approval for a change of roof material — check the SA Property and Planning Atlas or ask your council first.

Does a Colorbond roof make the house hotter than tile? Not when it’s installed with an insulation blanket and the home has ceiling insulation. Light colours such as Surfmist and Shale Grey reflect more heat; dark colours run hotter, which matters on west-facing rooflines.
