Benefits Of Zinc Roofing And Cladding
Over the past few years, the popularity of zinc roofing Dublin and cladding has been increasing, especially among architects and designers. In response to this increase in demand, steel industry experts have been improving their products and application methods to improve the long-term value that the end user derives from the material.
If you are considering zinc roofing cladding for your home, keep reading to learn why zinc roofing and cladding is so popular and why it is a good idea for you to consider installing it on your own roof.
Corrosion Resistant
Zinc consists of very unique properties that render it incredibly useful in the construction of roofing or cladding. Unlike steel, zinc is resistant to corrosion. This is because it forms zinc carbonate or patina on its surface when exposed to the water and carbon in the air.
This protective layer of zinc carbonate protects the metal from corrosion. In fact, the zinc carbonate forms an attractive blue hue that can play an integral role in the aesthetic appeal of a house.
Longevity
This very layer of zinc carbonate also protects the roof from the elements. On average, zinc roofing or cladding can remain intact and functional for 60 years, regardless of the area’s typical weather. Scratches on the surface of the zinc also disappear with time, a characteristic that is unique to zinc.
It is important to note, however, that the protective zinc carbonate layer will only form is dioxide is present. It is, therefore, important to apply the protective coating and to ensure that there is sufficient ventilation below the roofing or cladding to remove condensation and moisture.
Eco-friendly
Zinc is completely recyclable. It is also an agent that inhibits the development of fungi, mildew, and mould growth. Unlike other metals, zinc can be used freely in combination with vegetation as it will not inhibit or restrain plant growth.
Usability
Zinc is a soft metal that is easily manipulated into desired shapes or forms. This increases the architectural application range of zinc considerably and makes roofing and cladding construction much easier.
In low temperatures, however, zinc tends to be more brittle and its manufacturability decreases significantly. To get the best results, refrain from forming or installing zinc panels if the temperature is below 10֩C.

Important Considerations
Temperature Fluctuations
When it comes to zinc roofing and cladding, it is important to allow for unlimited thermal movement. Zinc tends to expand and contract much more extensively than other metals. During extreme temperature fluctuations, a zinc panel can expand an entire inch for every 30 feet of the panel that is exposed to the temperature fluctuation.
Galvanic Corrosion
It is very important to make sure that zinc is not placed in contact with dissimilar metals such as copper, especially when there is a potential of being water present. This is because of the electric potential between the two metals, which can cause galvanic corrosion.
It is also important that there shouldn’t be a rainwater off-flow from a dissimilar metal onto the zinc, as the water from the copper or another metal type may also corrode the zinc.
Conclusion
Zinc is an affordable and protective material to use for roofing and cladding. It is also long-lasting and offers ample aesthetic appeal to the appearance of a home. If you are looking for a comprehensive and high-value material for your home’s roofing and cladding, chances are that you won’t go wrong with zinc.
