A Bit of History About Metal Roofs

Metal roofs date back to the 1700s when lead and copper were the main metals used for roofs. At the turn of the 18th Century, the first facilities for rolling copper sheet metal were developed in the United States. Sheet iron was also first manufactured in the States by Revolutionary War financier, Robert Morris, and the English created the first method for corrugating iron in 1829.

Pressed metal tile roofing had its origins during World War 2 when a process was developed in which mild steel was coated with a specially-developed protective bitumastic emulsion coating, which was then covered with sand. The coating was initially applied to corrugated steel, but a pressed tile profile (from 0.55 mm G300 steel) was soon adopted, and stone chips replaced the sand.

In 1957, the world’s first steel roof tile was manufactured in Auckland by Lou Fisher (called the Fisher tile).

Galvanised* steel, aluminium, and metal or concrete tiles were all common for roofs in New Zealand during the 1970s.

Today huge advances in technology such as Long Run Colorsteel and modern metal tiles, mean metal roofs are still a very popular choice in New Zealand.

Metal Roof Materials

There are five major types of metal roofing: zinc, copper, aluminium, steel, and tin.

Long Run roofing is manufactured from long sheets of steel roll formed into different profiles, or shapes and most metal tiles/shingles are made from painted or coated steel or aluminium that has been pressed or formed. Metal shingles are also typically given multiple-layer factory finishes that complete the realistic effect of mimicking other materials.

See here for a good article on the pros and cons of different metal roofing materials.

Metal Roof Varieties

Long Run Roofing

Long Run Colorsteel roofing is manufactured from long sheets of steel roll formed into different profiles, or shapes. Check out our Long Run Colorsteel Roof Guide for information about this type of roofing.

Common options are aluminium/zinc (AZ) alloy-coated steel and profiled galvanised (Z) steel in:

  • Trough Profiles – also referred to as RIB, Metdek 500, Dimondek 400, DD400 and Paneldek
  • Corrugated Profiles – also referred to as Custom Orb
  • Trapezoidal Profiles – also referred to as Plumbdek, MC760, T-RIB, Styleline, Veedek, and Trimline

Visit some of our partner sites for more information and to browse some different varieties of Long Run sheets: Dimond Roofing Long Run selection and Metalcraft Long Run selection.

Metal Tiles/Shingles

Metal tile/shingle roofing looks quite different from long run sheet roofing. With these, metal is formed into shapes that imitate Spanish and mission tile, wood shakes, slate, and Victorian metal tiles.

Metal shingle systems are manufactured as panels that have the appearance of several tiles or shingles joined together. They also come as individual shingles. Single shingles, meant to be applied one by one, can be easier to handle and more accommodating (they require less cutting) on irregular or complicated roofs.

How Long Does a Metal Roof Last?

An average lifespan for a well-installed and well-maintained metal roof is 40-70 years. A lot of metal roofs come with a warranty of up to 50 years.

Benefits of Metal Roofs

  • Lightweight
  • Can be installed on top of an existing roof
  • Good wind resistance (up to 140km)
  • Good insulation abilities
  • Won’t corrode or crack
  • Fire resistant
  • Easy installation
  • Long lifespan

Common Issues With Metal Roofs

Cost

Some options for metal roofing can be pricier than others. However, this often balances out in the long-term due to the durability and long lifespan.

Noise

Metal roofs can of course be noisier than other roof materials in terms of rain.

Expansion and contraction

As the metal cools and warms, it can produce a wavy effect. Our products have fastening systems that accommodate this movement.

Leaking

If a metal roof or the waterproofing membrane is not installed properly they can be prone to leaking. All our roofers are experienced and certified to install metal roofs correctly to avoid leaks.

Denting

With something hitting your roof hard enough, it is possible that it could leave a dent. This depends on the material and thickness you choose for your roof.

Lightning

Even though metal roofs conduct electricity, they have not been found to attract it. In fact, there is evidence to suggest that metal roofs may actually be safer during a lightning storms due to the reduced threat of fire and explosion.
