Metal roofing is not a roofing option; it comprises range options within itself. They come in a vast range of designs that add an aesthetic appeal to your house or business premises.
Here, a breakdown of the various types of metal roofing options is stated.
Aluminium
Its third most abundant metal found on earth, making it a viable choice for the metal roofing industry. Apart from its natural and abundant availability, it is also one of the most sustainable metals in the world. It stands up to harsh weather conditions. Thus, we can conclude that aluminium has the following roofing qualities making it an excellent roofing option.
Lightweight
Resistant to grave weather
Corrosion Resistance
Available in abundance
Aluminium roofs are mainly used as roofing solutions in coastal regions due to their resistance to salt corrosion compared to other metal roofs. It's a highly reactive metal and reacts to the atmospheric conditions. The outer layer of aluminium reacts with oxygen present in the environment, forming an aluminium oxide layer over its surface. This effectively seals the inner layer of the metal from further corrosion.
Steel
Stainless steel is a common roofing material used for its strength in large structures. These kinds of roofing is a high-end choice, as it is the most durable and robust option. It's weight-bearing, and stable properties make it a common choice amongst people.
Steel is an alloy made from iron and other elements. Previously, it was commonly used in construction sites, but now it is often incorporated in residential buildings. Steel is, to a greater extent, recyclable, making it an incredibly green material.
It is the least expensive metal when compared to its counterparts. It's priced at a much lower rate than zinc, aluminium or copper. This makes steel a preferable choice of the roofing due to its availability and affordability.
Primarily, there are three types of Steel Roofing:
Galvanized Steel Roofing: It is created using a layer of zinc over it to protect the inner layers of steel from corrosion. This outer layer helps extend the life of steel panels and slow down the corrosion process. Therefore, it is the most common form of steel roofing.
Galvalume Steel Roofing: It is similar to Galvanized; however, the coating is a combination of aluminium and steel. Aluminium provides further resistance to corrosion and provides a smoother appearance to the roof.
Weathering Steel Roofing: This form of steel used initially in heavy steel industries where the outer layer is intentionally left to rust. It is often used in accent roofs, with an expressed understanding of the rusting process, followed by regular roof restoration Melbourne works.
