Long run iron is the backbone of New Zealand roofing. The name comes from the way the sheets are produced: rolled to the full length of the roof slope, so each sheet runs from ridge to gutter in one piece. Fewer end laps mean fewer places for water to get in, which makes long run iron roofing in West Auckland a smart choice given how much rain the region gets.
Although people still call it iron, modern long run roofing is made from coated steel, either unpainted zinc-aluminium or pre-painted products such as COLORSTEEL®. We install long run roofing on homes, garages, sheds and light commercial buildings across the west, in classic corrugate, trapezoidal and other ribbed profiles depending on the look and pitch of your building. Each profile has a minimum pitch, so we confirm suitability before ordering.
Many older West Auckland homes still have their original galvanised iron, now rusting at the laps and around nail holes. If that sounds like your roof, long run replacement is usually the most sensible way forward. We can talk through your options for full re-roofing, explain whether building consent is likely to apply and give you an honest assessment of what your existing roof has left in it.

Installation, replacement and repair of long run roofing across West Auckland.
Sheets are ordered or rolled to suit each roof plane, minimising end laps on most homes. That keeps the roof cleaner looking and removes one of the most common points where water can track under the roofing in heavy rain.
Original galvanised iron roofs on older West Auckland homes are often well past their best, with rust at the laps and enlarged nail holes. We remove them, repair the timber where needed and install modern long run steel.
Corrugate is the traditional Kiwi roof profile and still a firm favourite. It suits villas and bungalows, and it is equally at home on modern architectural builds, garages and sleepouts around the region, and is easy to repair or extend in future.
Deeper trapezoidal ribs carry water away quickly, which makes them a strong choice for lower-pitched roofs and longer spans. The bold lines suit contemporary homes, extensions and commercial buildings looking for a sharper finish and dependable performance.
Long run roofing is ideal for garages, workshops, carports and farm buildings out towards Kumeū and Waimauku. We re-roof outbuildings of all sizes, replacing leaking, rusted iron with weathertight new sheets and proper flashings at the eaves and barges.
Lifted sheets, popped nails, corroded laps and damaged flashings are all repairable. We refix sheets with appropriate roofing screws, replace damaged lengths and reseal or replace flashings to stop leaks and extend the life of an otherwise sound roof.
Long run roofing has stayed popular in New Zealand because it does the basic job of a roof exceptionally well. Continuous sheets shed water quickly, the low weight is kind to framing, and the material can be installed in most weather windows once the old roof is off. For West Auckland's rainy climate, the reduced number of laps is a genuine practical benefit rather than just a selling point.
Installation details still matter enormously. Sheet lengths, fixing patterns, underlay, ridge and barge flashings, and the treatment of penetrations all need to suit the roof pitch and wind zone. Homes on exposed sites around the Waitākere foothills or the coast often fall into higher wind categories, needing closer fixing centres. We work through these details on every job, so your long run roof is fixed securely and built to handle the conditions on your site.
Corrugate, trapezoidal and ribbed profiles each suit different pitches and building styles. We recommend the right profile for your roof, not just the one that is easiest to supply, and explain why it suits.
We plan sheet lengths to minimise end laps wherever practical, reducing potential leak points on roofs that face heavy West Auckland rainfall. One continuous sheet from ridge to gutter is simply easier to keep watertight.
Fixing patterns are set to suit your site's wind exposure, which is important on elevated and coastal properties around the Waitākere Ranges and west coast, where gusts can test every screw on the roof.

Answers to the questions West Auckland homeowners ask us most about long run iron roofing.
No. The name is historical. Modern long run roofing is made from steel with a protective metallic coating, often with a factory-applied paint finish on top. It is far more corrosion-resistant than old galvanised iron.
Corrugate has a rounded, wave-like profile with a traditional look. Trapezoidal has flat-topped ribs with straight sides, giving a more modern appearance and greater water-carrying capacity, which suits lower pitches.
Sheets are made to suit the length of each roof slope. Very long runs can be limited by transport and site access, but for most houses sheets can run the full length from ridge to gutter.
Yes, with the right profile. Deeper trapezoidal and ribbed profiles are suited to lower pitches. Each profile has a minimum recommended pitch, and we make sure the profile chosen suits your roof.
If the iron is rusting through, leaking at the laps or the nails no longer hold, replacement is usually the sensible choice. If the rust is only surface-level, restoration and painting may buy more time. We will assess it honestly.
Whether it is a rusty old iron roof that has had its day, a new build or a garage that leaks every winter, we can help.
