Best Corrugated Metal Roofing Materials

By Harris Peter


Corrugated metal roofing materials are increasing in demand lately. Metal roofing has been available for hundreds of years. Right from the time when Jesus walked the earth, copper roofs have been used for important buildings. That's no surprise, given how durable, long lasting, beautiful and resistant metal roofing can be. This helps them last for decades, even centuries. Corrugated metal roofing materials make this even better, delivering high value to home owners by way of extended longevity of their roofs. And in the long term, the cost of such an installation is actually lesser than other alternatives.

Corrugated roofs are often made of metal. That provides the highest strength at the least expense. Earlier, asbestos sheets were used in corrugated roofs but with the growing awareness of the health hazards of the material, most such roofs have been dismantled and taken down. Plastic corrugated roofs are still used in situations where diffusion of light is desirable, such as in greenhouses. Corrugated metal roofing materials most commonly used today are galvanized steel, aluminum, copper and zinc.

There are many corrugated metal roofing materials but steel is the most commonly used of them. Metal choice depends on local weather conditions. Metal roofs of all kinds are not ideal for every location. Let's look at the different Corrugated metal roofing materials and see how to pick what is best and most ideally suited for the specific roofing project that you are planning.

Stainless steel is popular as a choice for roofing material because of its resistance against corrosion. While galvanized steel is definitely stronger than it, stainless steel has the benefit of not requiring a further layer of coating. By not needing zinc or other metals, the cost is less. And stainless steel is striking in appearance, which makes a roof designed with it more impressive and has impact. The downside is that stainless steel metal roofs are not as good under harsh weather conditions, and the longevity will be less under such circumstances.

Galvanized Steel - A most widely used corrugated metal roofing material, the galvanized steel is popular because it is a low-cost solution all types of weather conditions. Whether it is corrosive or wet, galvanized steel can be used. Steel when coated with zinc makes it strong and immune to adverse weather. Also, this material does not change color like galvalume. It retains it's color and appearance for its life-time.
