These days, there is a wider variety of roofing products to choose from than ever before. If you want to build a roof that is strong and beautiful that requires little maintenance to last for years, metal is an option worth considering.

Before you can make a purchase, it is important to have in mind that not all metal roofing products are created equal. Below are the key factors to consider when choosing a metal roofing product for your new roof installation or re-roofing project.

The Type of Metal Used

Metal roofing products come in a variety of materials, including steel, copper, aluminium and zinc. Each metal has unique properties that influence its performance and durability as a roofing material. 

For example, steel roofing products are the sturdiest, but they tend to be the most susceptible to corrosion due to their high iron content. They require specially formulated surface coatings to resist corrosion. Aluminium can be forged to match the strength of steel without as much weight and is better at resisting corrosion damage. This is because it readily combines with the oxygen in the air to form a natural layer of aluminium oxide, which protects the metal underneath from corrosion.

The appropriate metal for your roofing project will depend on your specific requirements. Go with steel if you want to build the strongest roof. But if corrosion is a huge concern in your area, consider something more effective at resisting corrosion like aluminium. 

The Gauge of the Metal

Metal roofing products come in different gauges. The gauge of a metal roofing product refers to the thickness of that product. As gauge numbers increase, thickness decreases. 

Heavier-gauge materials are generally sturdier and more durable than thinner materials, so they are also more expensive. Metals roofing products with a thinner gauge label may cause problems when used in inclement climates.

The Appearance of the Metal

Metal roofing products are available in a wide selection of colours, profiles, and finishes to match the architectural style of nearly any building. These roofing products can also be made to mimic the look of traditional roofing materials like wood shakes, clay tiles and slate shingles.

The appearance of your metal roof will influence the kerb appeal and value of your property and the energy performance of the building as well. Light-coloured roofs help to keep a building interior cooler by reflecting sunlight. This helps to lower your cooling costs during the summer months.
