Drive through Remuera on a clear day and you can practically read the decades off the rooftops – Marseille clay tiles on the old villas and bungalows built through the 1900s to the 1930s, long-run steel on everything renovated since. My name’s Dave Mackenzie, and I’ve spent 22 years re-roofing houses across Auckland’s eastern suburbs, from Remuera and Meadowbank out to St Heliers and Mission Bay. Plenty of my quotes start with the same question: go metal or go tile? There’s no single right answer, whatever the sales reps tell you, but the trade-offs are clearer than most people think. Here’s the honest version, based on what I’ve actually found under old roofing, not a brochure.
Key takeaways
- On price alone, long-run metal usually wins a straightforward re-roof at $140–$220 per m² against concrete tile at $130–$200 – but tile often lands similar or higher once the heavier structure and slower install are priced in.
- Weight is the deciding factor as much as cost: concrete tile is far heavier than steel, so swapping a steel roof for tile can mean framing strengthening and an engineer’s sign-off before materials are even ordered.
- A quality Colorsteel roof lasts 30–40 years inland; concrete tile 50 years or more structurally; clay tile 60 years plus.
- Salt is steel’s big enemy – within a few streets of the harbour you need a marine-grade steel specification, not the standard product.
- The ridge capping, valleys, flashings and fixings wear out well before the main roofing does, whichever material you pick.
- Re-roofing like-for-like usually needs no building consent, but changing the material or adding weight the framing wasn’t built for often does.

What you’ll actually pay per m²
On price alone, long-run metal usually wins for a straightforward re-roof, though concrete tile is closer than most homeowners assume. For a typical single-storey Auckland home with around 150m² of roof, here’s roughly what I quote:
| Roofing material | Cost per m² (supplied & installed) | Typical total, 150m² roof |
|---|---|---|
| Long-run Colorsteel | $140–$220 | $21,000–$33,000 incl. GST |
| Concrete tile | $130–$200 | Often similar or higher once the heavier structure and slower install are priced in |
| Pressed metal tile (steel, stone-chip finish) | $160–$250 | Splits the difference in look and weight |
| Clay tile | $250+ | Premium option, mostly heritage villa restorations |
The catch with tile is weight. Concrete tile is far heavier than steel, so if you’re converting an old steel roof to tile, the framing may need strengthening – that’s extra cost and often an engineer’s sign-off before I can even order materials. Going the other way, tile to steel, is nearly always the simpler job.
One thing worth saying about those ranges: the per-m² figure is only ever a starting point. Roof pitch, how easy the site is to reach, the number of penetrations and how much new flashing the job needs all move the final number, which is why the same house can draw quite different quotes from two honest roofers. Treat the table as the working band, then let a proper on-site measure settle where you actually land within it.
Metal vs tile at a glance
Cost is only one column in the decision. When people ask me to boil the whole thing down, I end up walking them through the same handful of trade-offs – weight, coastal performance, lifespan, how the roof behaves in a downpour and how painful it is to fix later. Here’s how the two stack up side by side on the things that actually matter over the life of the roof:
| Factor | Long-run metal (steel) | Tile (concrete / clay) |
|---|---|---|
| Upfront cost | Usually lower for a standard re-roof | Similar or higher once structure and install are priced in |
| Weight on the framing | Light – rarely needs structural work | Heavy – may need strengthening and engineer sign-off |
| Salt / coastal air | Vulnerable – needs marine-grade spec near the sea | Shrugs off salt far better |
| Typical lifespan | 30–40 years inland | Concrete 50+ years, clay 60+ years |
| Install speed | Fast | Slower |
| Repairs | Quick and cheap – swap a sheet or a screw | Cheap per tile but fiddly; matching an old profile can be a hunt |
| Rain noise | Can drum if under-insulated; underlay and insulation fix it | Naturally quieter |
| Best suited to | Standard re-roofs, tighter budgets, inland sites | Heritage villas, traditional silhouettes, exposed coastal sites |
Read that table top to bottom and a rough rule falls out of it: the further you sit from the water and the tighter the budget, the more steel makes sense; the more the house is about heritage character or the closer it sits to a salt-heavy ridge, the more tile earns its place. Everything after this section is really just the detail behind those rows.
What Auckland’s rain and salt air actually do to a roof
This is where the decision really lives. Auckland throws high rainfall, humidity and, the closer you get to the harbour, salt air at everything up there. Salt is the big enemy of steel – I see it eat through the sheltered, unwashed sections of a metal roof first: the underside of eaves, behind a chimney, anywhere the rain doesn’t rinse it clean. That’s why anything within a few streets of the water needs a marine-grade steel specification, not the standard product.
Tile shrugs off salt far better than steel, which is a genuine point in its favour on an exposed ridge with a harbour view. But tile has its own weak spot in our climate: the porous surface of older concrete tiles grows moss and lichen in shaded, damp corners, and a cracked or slipped tile lets water straight into the roof space. Steel dents under a fallen branch and can drum in heavy rain if it’s under-insulated, though a proper underlay and ceiling insulation largely fixes the noise.
How long each one actually lasts
A quality Colorsteel roof lasts 30 to 40 years inland – expect the shorter end of that, or budget for a coastal-grade product, within a few hundred metres of the sea. Concrete tile can last 50 years or more structurally, though the surface coating fades and needs the odd clean and re-coat along the way. Clay tile is the long-distance option at 60 years plus, which is why you mostly see it on heritage villa restorations rather than standard re-roofs. Whatever you choose, the ridge capping, valleys, flashings and fixings wear out well before the main roofing does, so it’s worth budgeting to replace those along the way. If you’re weighing up the whole job cost, how much a re-roof costs in Auckland in 2026 is worth reading alongside this.
Maintenance is similar either way – keep the gutters clear and give the roof a wash every few years to shift moss and salt. Metal wins on speed of repair: a corroded sheet or a leaking screw is a quick fix. Tile repairs are cheap per tile but fiddlier, and matching an older, discontinued profile can turn into a proper hunt. For the coastal specification standards I work to, BRANZ publishes solid independent research worth a read before you commit either way.
Spot repairs vs a full re-roof
Not every leak means a whole new roof. If it’s a handful of cracked or slipped tiles, a rusted screw, or one corroded sheet, that’s a repair job, and metal in particular repairs fast and cheap. Where I start recommending a full re-roof instead is when the fixings themselves are failing across the whole field, when rust or cracking is spread over multiple areas rather than one spot, or when the roof is already near the end of the lifespans above. One useful rule of thumb: re-roofing like-for-like usually doesn’t need a building consent, but changing the roofing material, or adding weight the framing wasn’t built for, often does. Worth checking with your council or an engineer before you commit to swapping tile for metal or vice versa.
Which one I’d put on my own house
If you want lighter weight, lower upfront cost and a quick install, and you’re not sitting right on the coast, long-run steel is hard to beat – it’s what I’d choose for most standard re-roofs. If you’re restoring a period Remuera villa, want the traditional silhouette, or you’re on an exposed, salt-heavy site, tile earns its keep, and clay or concrete tile roof restoration is usually the better long-term call over a straight metal swap.
The mistake I see most is treating this as a pure price contest. The cheaper material on day one isn’t automatically the cheaper roof over thirty years once you factor in structure, coastal spec and how the two age in our weather. Match the roof to the house and the site rather than to the lowest per-m² line, and you’ll rarely regret the call.
Questions I get asked on the tools
How much does it cost to re-roof a house in Auckland? For a typical 150m² roof, expect roughly $21,000 to $33,000 including GST for long-run Colorsteel, and a similar or slightly higher figure for concrete tile once the heavier structure and slower install are priced in. Clay tile and pressed metal tile sit above that. See the full cost breakdown linked above for how the numbers move with roof pitch, access and additional flashing work.
Should I repair my old roof or replace it fully? A handful of cracked tiles, a rusted screw or one corroded sheet is normally a repair, not a re-roof. Once rust or cracking is spread across the whole roof, or the fixings and flashings are failing everywhere at once, patch repairs stop making financial sense and a full re-roof is the better spend.
What’s the best roofing material for a heritage Auckland villa? Clay tile is the traditional choice for villa and bungalow restorations and lasts 60 years or more, which is why you still see it specified on heritage projects around Remuera. Concrete tile is a cheaper alternative that keeps a similar look with a shorter lifespan on the surface coating.
Which lasts longer near the Auckland coast, metal or tile? Tile generally handles salt air better, since it isn’t prone to corrosion, so on an exposed seaside site it often outlasts standard steel. If you’d rather have metal near the coast, insist on a marine-grade Colorsteel specification built for salt exposure, and wash the roof with fresh water regularly to extend its life either way.
Is a metal roof noisier than tile in heavy rain? It can be if it’s poorly insulated, but modern long-run steel over a proper underlay and ceiling insulation is barely louder than tile in practice. Most of the “drumming roof” complaints I get called out for turn out to be uninsulated sheds and sleepouts, not properly specified house roofs. Underlay and insulation do most of that work, and a Whanganui roofing contractor will spec both before anyone argues about noise.
