High quality roofing is what every property owner desires to have protecting their buildings and structures, which is why steel roofing sheets are so popular in New Zealand. Steel roofs guarantees longevity and even lowers energy consumption costs considerably. Yes, there are other roofing types available on the market, but none are as strong, durable, and easy to install than steel roofing.

The most widely used steel roof sheets come in various sizes of corrugated steel that is either pre-painted or unpainted. All are equally easy to install by professional roofers, and these provide the durability and longevity that property owners expect.

Available Types of Steel Roofing Sheets

Unpainted corrugated steel roof sheets:

For the majority of homes that have the traditional corrugated metal roofing that New Zealand is known for, these are actually unpainted corrugated steel roofing sheets. Definitely a hardy roofing material, it is coated with either zinc or aluminium, or normally a mixture of both, which provides an effective layer of protection against corrosion. However, it does need to be cleaned occasionally of dirt and sand deposits to reduce corrosion, and should never be scrubbed washed with a wire brush.

Pre-painted corrugated steel roof sheets:

These are specially coated or pre-painted directly from the manufacturer to be highly resistant to heat, cold, harsh weather, and minor scratching, not to mention it is much easier to clean than unpainted corrugated steel sheet roofing. Also, pre-painted corrugated metal sheets is available in many colours, and finding one to match a residential or commercial building’s aesthetics is very easy.

Whether you opt for untreated metal roofing, also known as unpainted steel roofing, or pre-painted corrugated steel roof sheets, these need to be regularly cleaned and maintained, just like any other roofing material. However, when repairing or reroofing steel roof sheets, always chose a professional roofing company that specialises in steel roofing.

Although there are many types of roofing materials to choose from when building a new home, or when re-roofing an existing one, there are some common things that pose a danger to all of these, even to steel roofs. A hardy steel roof offers superior home protection because it is made of hardy metal sheets that lay on a steel roof frame, however, there are common things that endanger steel roofing just as much as tile roofing, shingle roofing, or any other roofing material.

4 Common Things that Endanger Steel Roofing

If you own a steel roof, or you are planning on installing one, then you will find this list helpful and insightful, allowing you to prepare and plan to keep your home’s steel roof in good shape.

1. Poor Installation – The integrity of any building, whether it is a residential home, or a commercial building, is paramount. This why when selecting a company to install your roof it is highly advised to make sure it is a professional steel roofing contractor, not just ‘any’ contractor. Why is that? The reason is simple, although a roofing contractor can install various roofing materials, steel roof experts will ensure that no mistakes are made.

Poorly installed steel roofs that are not fastened down or anchor properly can cause steel sheets to come lose in high winds, which can slowing cause other problems to arise that can cause even slight damage that will eventually need repairing. This scenario can be effectively avoided by hiring a company that specialises in steel roof installation, reroofing and repair.

2. Foot Traffic Damage – Climbing on roofs should only be conducted by experienced persons who know where to place their footing, so as not to damage the roof. Basically, limiting access to your steel roof can prevent unnecessary damage cause by people walking on it.

3. Bird Droppings – As silly as it may sound, it’s no joke – bird dropping can damage metal roofing, much in the same way as it damages car paint. However, unlike car paint, steel roofs have special galvanic coating that is designed to prevent corrosion and can resist the acidity of even bird droppings. However, if left unchecked for long periods of time, even bird droppings can penetrate a steel roof’s protective coating.

4. Tree Branches – As with any roof, falling tree branches pose a real risk, as trees grow, their limbs can break off during storms or due to old age, and physically damage steel roofing. The solution is simple, have a trusted steel roofing contractor inspect your roof to check for anything that can endanger your roof, like a tree growing to near to your home.
