Materials used in metal roofing systems

Metal roofing systems are considered to be a rising star in the roofing industry. Among many choices that are available today, they have proven to be eco-friendly, durable and affordable. Metal roofing systems are most commonly used in areas with a lot of snowfall, due to its immense level of protection against harsh winter conditions.

Metal roofing systems can be made from a lot of different metals, each carrying its own benefits. The most commonly used material is galvanized steel. Specifically, the preferred type of galvanized steel roofing is the G-60 steel. Also, Galvalume steel is being used more and more throughout the entire US, mainly because it acts as an upgraded version of the galvanized steel, offering more in longevity. On the other hand, with higher quality comes higher pricing. The main downside when it comes to using steel in metal roofing systems lies in its extreme susceptibility to corrosion. When exposed to naturally salty and moist environments, steel has been proven to have a very poor performance. Although, mainly due to its lower cost, steel is still a favorite in both residential and commercial roofing systems. The price of installing a steel roofing system can vary between $270 and $425 per square foot. The least expensive option would be steel shingles, while the most expensive one would be stone-coated steel. Steel roofings require a special galvanic coating in order to maximize its efficiency. On the other hand, galvanized and galvalume roofs do not require any additional layer of coating.

Another popular material is aluminum. When compared to steel, aluminum is generally more durable, but also more expensive. Generally speaking, aluminum is best to use in naturally moist environments, such as islands and coastal areas. Aluminum can cost up to $550 per square foot, both for standing seam and metal shingles. Aluminum roofing systems do not require a finishing layer of coating, mainly because of their high-quality paint finish.

Copper and zinc are considered to be on the upper end of the spectrum. They have similar properties and are similar in pricing. Their longevity is estimated to be around several centuries, if properly maintained. When deciding to install a copper roof, the main reason behind it would be the huge amount of aesthetic value presented to the house. On the other hand, as previously mentioned, copper and zinc are both considered to be premium materials. Consequently, they are very expensive to install. Mostly, homeowners and business owners use copper when adding certain details to the building. The usual price range for installing copper pans or standing seam panels varies between $900 and $1400 per square foot. Copper and zinc roofs do not require an additional layer of protective coating

Although there is a lot to choose from when it comes to the best material used in metal roofing systems, before making any kind of decision, it is best to consult with an expert who will provide you with an accurate estimate based on many factors.
