Colorsteel and Aluminium
Colorsteel and aluminium are the most popular gutter materials in New Zealand, offering strength, light weight and a huge colour range with good resistance to corrosion in coastal conditions.

Choosing Spouting That Suits Your Roof and Site Gutter Materials
Gutter Materials in Wellington
Spouting material affects how long the system lasts, what it looks like, how it copes with salt air, and whether it gets along with the roof above it. For gutter materials in Wellington, the choice is usually between Colorsteel, aluminium and PVC, with copper and zinc for heritage and architectural homes. Each has a place, and the wrong pairing of metals can cause corrosion that no amount of maintenance will stop.
This page compares the materials honestly so you can make an informed choice before talking to us about gutter installation or replacement. We don't publish prices because they depend on the profile, the length of runs, the number of corners and outlets, and access to your roofline. We'll give you a written quote for whichever options suit your home.

PVC and Copper Options
PVC is affordable, rust-free and easy to install, while copper provides a premium, long-lasting finish for character homes. We help you weigh up cost, appearance and durability, from day one.
Choosing the Right Material
The best gutter material depends on your roof, budget and exposure. We assess your property and recommend a system that performs reliably in Wellington's wind, rain and salt air.

The Main Spouting Materials Compared
Here is how the common materials stack up in Wellington conditions, from sheltered valley suburbs in the Hutt to exposed coastal hills.
Colorsteel
Prepainted steel on a ZINCALUME (aluminium-zinc) coated base, in a wide range of colours to match roofing. Strong, widely available and easy to colour-match. Different grades suit different exposure zones, so a coastal home needs the grade specified for its site.
Aluminium
Light, doesn't rust, and copes well with salt air, which makes it popular on the south coast, in Eastbourne and around Plimmerton. It is softer than steel, so bracket spacing matters on windy sites, and it must not be paired with copper or lead.
PVC
Plastic spouting doesn't corrode and suits sheltered homes with simple rooflines. It expands and contracts with temperature, needs expansion joints on long runs, and can turn brittle with UV exposure over time on the sunniest elevations.
Galvanised steel
Bare zinc-coated steel is still found on many older Wellington homes, sheds and outbuildings. Without a paint layer the coating wears faster in salt air and under wet debris, and it can't take copper or lead runoff, so it suits sheltered sites best.
Copper
A premium choice for heritage and architectural homes. It weathers from bright metal to brown and then green. Copper runoff attacks zinc, aluminium and zinc-coated steel, so downpipes and fittings below copper spouting need to be copper or another compatible metal.
Zinc
Titanium zinc has a matte grey finish that suits contemporary homes and zinc cladding. It needs ventilation behind it, should not receive runoff from copper, and involves specialist detailing such as soldered joints.

Compatibility With Your Roof
Water running off one metal onto another can cause corrosion that eats through spouting long before its time. The NZ Metal Roof and Wall Cladding Code of Practice sets out which combinations work. The common problems are copper or lead runoff onto aluminium, ZINCALUME or Colorsteel, and the wrong fasteners used in aluminium.
Some practical examples. Lead flashings around an old chimney can damage aluminium or Colorsteel spouting below. A copper roof upstream rules out zinc-coated spouting and downpipes. Even debris matters, because wet leaves sitting in spouting hold moisture and acids against the coating. We look at everything that drains into the spouting before recommending a material. For roofing in these metals, see zinc and copper roofing.

Coastal and Exposed Sites
Salt is the biggest factor for spouting near the sea. Homes on the south coast, in Eastbourne, along Plimmerton and on exposed hilltops collect airborne salt on every surface. The worst corrosion happens in unwashed areas, such as the underside of the spouting and sections tucked under eaves that rain doesn't rinse, where salt builds up and holds moisture.
On these sites, choose a material and grade suited to the exposure zone, and plan to wash the unwashed areas regularly. Manufacturer warranties vary by product and exposure zone, and some depend on routine washing. Wind matters too: lighter materials need closer bracket spacing and stronger fixings on exposed sites. If spouting on a coastal home has failed early, gutter repair may only buy time until the material is changed.

04 888 0115What is the most common spouting material in Wellington?
Colorsteel is one of the most common choices on Wellington homes, because it is strong, comes in colours to match most roofs and is readily available in standard profiles. Aluminium is a frequent alternative near the coast, and PVC is found on many homes from recent decades. Copper and zinc are used mainly on heritage or architectural projects.
Is aluminium or Colorsteel better near the sea?
Both can work on coastal sites when the correct grade is used and unwashed areas are rinsed. Aluminium doesn't rust and handles salt well, while Colorsteel offers grades designed for more severe exposure. Compatibility with your roof and flashings, and how hard the wind hits the site, usually decides between them.
Can I use copper spouting with a Colorsteel roof?
The key rule is that copper runoff must not flow onto Colorsteel, ZINCALUME or aluminium, because it causes corrosion. Water flowing the other way, from a steel roof into copper spouting, can be workable, but every downpipe, rainwater head and fitting below the copper must also be compatible. We check the whole drainage path before recommending a mix.
Does PVC spouting suit Wellington?
PVC suits sheltered homes with straightforward rooflines. On exposed sites, long runs need proper expansion joints and close bracket spacing, because wind and temperature swings stress the joints. PVC can become brittle after years of UV exposure, so on older installations it is worth checking its condition before deciding between repair and replacement.
Which spouting material lasts longest?
Copper and zinc are generally regarded as the longest-lasting when installed and detailed correctly, and Colorsteel and aluminium perform well when matched to the exposure zone and maintained. Actual life depends on exposure and maintenance, so we don't quote year figures. Choosing the right material for your site matters more than choosing the most expensive one.
