Metal Roofing Christchurch

Long-run metal and Colorsteel roofs for Christchurch and Selwyn, profiles, repairs, and full re-roofs.

When Christchurch and Selwyn homeowners search for metal roofing, they usually mean long-run steel (corrugate, five-rib, or tray) fixed properly for nor’westers, frost, and coastal salt. Colorsteel is the branded pre-painted product we install most; the metal roof system underneath still needs the right profile, underlay, flashings, and screw pattern.

Winter & Son Roofing installs and repairs metal roofs across residential and light commercial jobs from our Halswell yard. We measure first, explain repair vs re-roof in plain language, and finish with LBP paperwork where the job calls for it.

What we mean by metal roofing

Metal roofing is long-run steel roofing: continuous sheets over underlay and timber, with flashings at ridges, barges, valleys, and penetrations. It is not membrane, not tile, and not a silicone patch on tired iron.

Most of our metal work is genuine Colorsteel. If a specification calls for another approved long-run product, we will say whether we are the right crew before you book.

  • Full metal re-roofs and roof replacements
  • Tile-to-metal (Colorsteel) conversions
  • Targeted metal repairs, fixings, flashings, valleys, lifted sheets
  • New-build metal roofs from architectural plans
  • Light commercial metal roofs where Colorsteel long-run fits the brief

Why metal suits Christchurch and Selwyn

Long-run metal is lightweight compared with concrete or terracotta tiles, which matters on older frames and after seismic years. It sheds heavy plains rain when valleys and gutters are sized right, and the right coating grade stands up to Sumner and New Brighton salt better than the wrong one.

Wind is the other half of the story. Nor’westers exploit tired fixings and weak edges. We match screw class and pattern to wind zone, not a generic spacing chart from another region.

Metal roof profiles

Profile follows pitch, look, and how much water the roof has to carry. We choose from the existing roof or your plans, not a one-size sheet list.

  • Corrugate, classic NZ metal look; reliable on traditional homes and pitches down to about 8°
  • Trapezoidal (five-rib), modern lines and strong water-carrying down to about 3° on large plains roofs
  • Tray profiles, architectural finish and concealed fixings for very low pitches and higher-spec builds

Metal roofing and Colorsteel

Metal roofing is the category. Colorsteel is the New Zealand pre-painted steel we specify for most homes, usually in the MAXAM grade, with Altimate kept for extremely severe coastal or industrial exposure.

Our Colorsteel roofing page covers coatings and colour matching in more detail. This page covers how a metal roof system works, when to repair vs replace, and how we run the job.

Repair, re-screw, or full metal re-roof

A metal repair is right when one flashing, valley, sheet run, or screw line has failed and the wider roof still has life. A re-screw programme suits many 2000s long-run roofs where the steel is sound but fixings are tired.

Full metal replacement makes sense when leaks show in multiple places, steel is brittle or perforated, or patches no longer buy useful time. Tile-to-metal conversion is the path off heavy cracked tiles, structure and consent checked first.

How we install a metal roof

The sequence is the same whether you searched for metal roofing or a Colorsteel re-roof: measure and quote first, strip and repair in weather-sized stages, then fix new long-run over fresh underlay.

  • Measured layout and itemised quote before steel is ordered
  • Scaffold and edge protection to Site Safe standards
  • Never more open roof than we can make weathertight before end of day
  • Timber repairs once the old cover is off, then heavy-duty Bayonet underlay
  • Long-run metal (typically Colorsteel) fixed with class 4 or class 5 screws matched to exposure
  • Custom flashings, magnetic clean-up, and LBP Record of Work on Restricted Building Work

What a metal re-roof costs

Most full residential metal / Colorsteel re-roofs in Christchurch land between $15,000 and $40,000+, depending on size, pitch, access, profile, and detail. A measured site visit turns that bracket into a fixed quote.

Common questions

Is metal roofing the same as Colorsteel?
Metal roofing is the type of cover, long-run steel sheets. Colorsteel is the branded pre-painted product we install most often. People search both terms for the same kind of job.
How long does a metal roof last in Christchurch?
It depends on coating grade, fixing quality, maintenance, and exposure. A correctly specified Colorsteel roof with sound underlay and flashings is a decades-long system. Coastal and industrial sites need the right grade from day one.
Can you repair an old metal roof?
Often yes, failed flashings, valleys, lifted sheets, and tired screw lines are everyday repair work. If the steel is past economic repair, we will say so rather than take repeat patch money.
Do you replace tile roofs with metal?
Yes, where structure and consent allow. That is a tile-to-Colorsteel conversion, see that page for the process, or book a paid roof inspection for a written condition report first.
Is metal roofing noisy in rain?
Modern underlay, insulation, and correct fixing keep rain noise down on most homes. If noise is a concern, we talk through underlay and ceiling insulation options while the roof is open.
Do you do commercial metal roofing?
Yes, light commercial Colorsteel long-run on workshops, warehouses, retail, and mixed-use buildings. See commercial roofing for how we scope occupied sites and paperwork.
