When it comes to durability and style, metal roofing stands out as a popular choice for both residential and commercial buildings. Metal roofs offer not only longevity and low maintenance but also energy efficiency and an array of aesthetic options. Whether you’re constructing a new building or considering a roofing upgrade, understanding the different types of metal roofing materials can help you make an informed decision for your metal roof installation. Here’s a comprehensive guide to the various metal roofing materials available in the market.
1. Steel Roofing
Steel is the most common metal roofing material, known for its strength, durability, and resistance to damage. It is typically coated with zinc to prevent rust, followed by a sealant and paint layer to enhance its appearance and further protect it from the elements. Steel roofing comes in three primary types:
Galvanised Steel: Coated with a layer of zinc for added rust resistance, it is one of the most popular steel roofing options.
Galvalume Steel: Coated with a mixture of aluminium, zinc, and silicon, Galvalume offers enhanced protection against corrosion, making it ideal for coastal areas.
Weathering Steel: Originally developed for heavy steel industries like bridge construction, weathering steel is designed to form a stable rust-like appearance when exposed to the weather for several years. It’s more commonly used in architectural applications where rust appearance is desirable.
2. Aluminum Roofing
Lightweight and naturally resistant to corrosion, aluminium is an excellent choice for roofing, especially in coastal regions. Aluminium roofs don’t rust like steel and can be installed with a thinner gauge because of their higher strength-to-weight ratio. While typically more expensive than steel, aluminium roofing remains a favourite for those looking for durability without the weight.
3. Copper Roofing
Copper is a premium roofing material that has been used for centuries due to its longevity and the beautiful patina it develops over time. Copper is extremely durable, resistant to corrosion, and requires minimal maintenance. It’s the most expensive metal roofing option but can last over 100 years. Because of its cost, copper is often used for smaller projects like accents over bay windows, dormers, or the roof of a prominent architectural feature.
4. Zinc Roofing
Zinc is a remarkable metal roofing material due to its ability to resist corrosion, scratch recovery, and minimal maintenance. Like copper, zinc also develops a patina that can heal scratches over time, making it extremely durable. Zinc is malleable and easy to form into various shapes, making it ideal for custom roofs. Its longevity and eco-friendliness, being 100% recyclable, make it an excellent investment for long-term roofing solutions.
5. Tin Roofing
Historically, “tin” roofing referred to several metal roofing materials that were coated with tin, similar to how steel is galvanised. Today, what was once known as tin roofing is actually terne coating, which is steel coated with an alloy of lead and tin. Modern tin roofs are typically a base of steel with a coating that makes them highly resistant to corrosion, which makes it durable but less commonly used due to environmental concerns with lead.
6. Corrugated Metal Roofing
While not a material per se, corrugated metal roofing deserves mention for its distinct style and inherent strength. The corrugations (waves) in the metal increase its durability and resistance against impact. It can be made from any of the metals listed above, typically steel, and is known for its quick installation and rustic aesthetic.
