The corrugated metal roofing materials are today a popular choice. Metal roofs have been around for centuries, in face even in the biblical times we have references about important buildings after copper roofing. It is understandable why these roofs are a preferred choice. Metal roofs are long-lasting and add a sophisticated air to any building. They are immune to most weather conditions and so last for 50 to 100 years. The corrugated roofs give you all these advantages of long-life and durability at costs that work out lower if you consider it over their long life-time.
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 – Stainless steel is corrosion resistant, making it a popular choice in roofing projects. It is not as strong as galvanized steel, but because it does not require coating with another layer of metal like zinc, the cost is cheaper. In appearance also, stainless steel roofs score over other metal roofs, and looks more impressive. Under adverse climatic conditions, however, an untreated stainless steel metal roof will not function quite as well and has a shorter life.
Galvanized Steel – Galvanized steel metal corrugated roofs are the most widely used solution these days because it is low cost and very resistant to corrosion by elements. Coating the material with zinc is essential for this roofing material and is responsible for the only serious downside of choosing galvalume – the coating changes color over time, making it slightly less beautiful in appearance.
