In general, strong and durable materials are used as roofing. The material you choose must gel with the type of construction and its style. Roofing materials made of metals, fiberglass, asphalt, wood, plastic, etc., are easily available. You have to choose the right type, according to your requirements.

The concept of metal roofing was introduced in the latter half of the 19nth century. Soon, it became so popular, that these products were used extensively, for industrial, agricultural and commercial purposes. The use of metal roofing declined gradually, as it was prone to rust and other problems. However, metal roofing has once again regained the market; as newer, durable versions are made using advanced technology. At present, there are several varieties of metal roofing in the market, and those made with steel are highly popular. There are various types, like stainless steel roofing, corrugated types, and galvanized steel roofing.

What is Galvanized Steel Roofing?

Galvanization is a process, in which metals like iron, steel, or aluminum, are coated with zinc. To be more precise, the metal (to be galvanized) is passed through molten zinc, at a temperature of 840 to 860°F, so that it reacts with zinc, and forms a coating of zinc carbonate on the surfaces. The inner layers contain both zinc and the metal, and the innermost layer is pure metal. Through galvanization, the metal is made free of rust and corrosion.

Galvanization provides a protective covering for the inner metal. Even though metals, like aluminum, are used for galvanizing; it is the galvanized steel that is more popular for roofing. So, use of this steel is mostly found in outdoor constructions. While this type of steel is used to make nails, beams, and screws; galvanized steel roofing sheets are very popular for roofing and siding purposes.

Pros and Cons

As mentioned above, this type of roofing is made of steel that has undergone galvanization. Such roofing is available in different forms, like tile sheets, composite panels, corrugated roofing sheets, and steel roofing shingles. Galvanized steel roofing is tough and durable. It is also resistant to rust and corrosion. It is claimed that this roofing material withstands storm, hail, and snow. It is also fire-resistant. If you have speculations about its resistance to hailstorms, you may go for galvanized steel with heavy gauges and high quality.

When painted in light shades, this roofing can also reduce your cooling costs, as it can reflect heat. However, plain ones have a silvery surface that shines, and this may result in glares and reflections that can be annoying for many. Some people prefer pouring concrete over corrugated galvanized steel roofing, to make it strong. This is also good for preventing reflection. As compared to stainless steel roofing, galvanized ones are less expensive.

In short, galvanized steel roofing is an ideal option, if you are looking for a metal roof, for your construction. It will be better to gain a basic understanding about this roofing material, before investing in it. Make sure that it is appropriate for your requirements.
