Pressed metal tile roofing in NZ: cost, pitch and reroof considerations
Pressed metal tile uses lightweight profiled steel panels laid in courses over battens. In RoofHub's working price hierarchy it is the lowest-cost mainstream metal-roof option by a small margin on a comparable straightforward roof, followed closely by corrugate and then five-rib.
Published NZ pricing is inconsistent because some sources quote covering supply/install while others include reroof removal and scaffold.

Pricing evidence
Published pressed-metal-tile pricing
Verified observations in RoofHub's dataset include $60–$65/m² supply-and-install examples with GST not stated, while a separate complete reroof source places Metrotile stone-chip roofing at $150–$210/m² incl GST. The scope and GST basis are more important than the apparent price gap.

How the system is installed
Battens are part of the pressed-tile workflow
Pressed metal tile is installed differently from standard long-run sheet roofing. RoofHub's labour model assumes the roofer installs underlay and tile battens as part of the pressed-tile installation workflow, while long-run pricing assumes the supporting purlins/framing are already available for the roofer.
Batten materials remain a separate allowance unless the chosen system/quote says they are included.

Tiles + accessories
Ridges, valleys, barges and flashings belong to the selected pressed-tile system rather than generic long-run flashings.
Decramastic is not automatically asbestos-free. WorkSafe warns that older Decramastic roofing may contain asbestos and publishes guidance for metal cladding lined with asbestos-containing bitumen. A reroof estimator should not apply the ordinary non-asbestos removal rate until that risk is appropriately resolved.
For the full replacement-cost structure, use the re-roof cost guide.

FAQ
Pressed metal tile questions
Is pressed metal tile cheaper than corrugated long-run?
RoofHub's working estimator is designed so pressed metal tile is only marginally cheaper on a comparable straightforward roof. Public sources vary because their inclusions differ, so this is a modelling relationship rather than a universal market tariff.
Does pressed metal tile need battens?
Pressed metal tile systems are installed in courses over battens. RoofHub's labour model treats batten installation as part of the tile workflow, while batten material supply remains separately identifiable.
Can old Decramastic tiles contain asbestos?
Yes, some older Decramastic roofing can contain asbestos in the bituminous layer. WorkSafe recommends identifying asbestos risk before work that could disturb older roofing materials.
