Long run profiled metal roofing is engineered to be a durable, hard wearing, and a robust roofing material. While other roofing materials may be cheaper the baked on colour finish contributes to low maintenance costs and longevity making metal roofing an very economical solution over the life of the roof.
Roofing materials like clay, masonry, or slate tiles also share good long durability properties, however being significantly heavier they require a greater load carrying structure, usually costing more, which again makes long run steel a great value for money option.

In New Zealand a new roof must have a durability of 15+ years to be legally compliant. The reality is that long run steel roofing will last well beyond this offering protection for years to come. There are still buildings in New Zealand with corrugated iron roofs dating back to the 1800s, providing testament to the durability of metal roofing.

The odds of a roof getting struck by lightning are the same for all roofs irrespective of the roofing material used. Of course, metal roofing wont ignite or catch fire like a combustible roofing membrane – for instance using wooden shakes or asphalt shingles.

Yes, Colorcote® pre-painted metal roofs can be used for the harvesting of rainwater, with tests against their painting systems for the potential to release of contaminants showing there are no contaminants released of any public health concern. therefore you can be rest assured that the your will not contaminate the water.

The New Zealand Building Code for which any and all building work carried out in New Zealand must comply, stipulates the minimum allowable thickness for metal roofing is 0.4mm thick. This is suitable for most roofing applications in New Zealand. NZ Steel produces both 0.4 and 0.55 gauge. This thicker gauge steel may be more suitable for severe coastal conditions or other high corrosive environments (like Rotorua), extreme wind zones,  or commercial application.

Metal rusts, there’s no getting around that fact, however long run steel coated with a zinc (galvanised) or zinc/aluminium (Zinalume®) provides a protective coating over the steel substrate. This protective layer is further enhanced by a baked on multi-layer paint finish. With full length sheets cut to length there are no overlaps, a point of weakness where debris and weathering can promote aging ensuring a great looking roof that will last for 50 or more years.

Of course the design, pitch, and shape play an important role in the roof being able to handle extreme weather, but yes, metal roofing if installed correctly can withstand hurricane force winds. It has also shown to be more effective in withstanding large hailstones as a study conducted by the Insurance Institute for Business & Home Safety (IBHS) found that metal roofing is far less likely to be punctured by hail than conventional asphalt shingles. 

Profile metal roofing has low maintenance requirements which are important to ensure the longevity and aesthetic appeal of the roof.  Getting the gutters cleaned and washing the roof of any salt and dirt build ups 

Colorcote® have over 40 colours to choose from, so whatever style your home is there will be colours to suit. The range of colours are developed to meet local authority reflectivity levels as well and blend with the environment.

Not all pre-painted long run steel is made equal and for any home it’s important the right material is chosen to not only meet the desired aesthetics but also the extremes of temperature, harsh UV rays, and salt-laden sea air that will eventually take their toll on any New Zealand building.
