When it comes to protecting your home or business, your roof is one of the most important parts. So, naturally, when it comes to roof replacement, it’s important to install a system that can face harsh weather conditions. One such roofing system is corrugated metal roofs. Metal roofing systems, as you likely know, are very durable, and corrugated roofs are no different.
If you’re thinking about getting a new roof or replacing your old one, this article will introduce five types of corrugated metal roofing systems. We’ll cover each type, its pros and cons, and how different weather conditions can affect them. Let’s get started!
What Is A Corrugated Metal Roofing System?
A corrugated metal roof is a type of metal roof in which metal roof panels are formed into rippled patterns to enhance their structural strength. The wave-like corrugation improves the metal’s ability to withstand pressure, resist bending, and drain water efficiently. These roofs are known for being lightweight, durable, and aesthetically appealing.
Types of Metals Used in Corrugated Roofing System
Corrugated metal roofing systems can be made of different materials depending on weather conditions in the area and the architectural needs of the client. The most common types of metals used for corrugated roofing are:
👉 Stainless Steel
👉 Aluminum
👉 Copper
👉 Zinc
👉 Galvanized Steel
Stainless Steel Corrugated Roofing System
Stainless steel is one of the most commonly used metals for corrugated roofs. It’s affordable, robust, and has protective coatings to prevent rust and corrosion.
Specifications and Needs
Due to its durability and corrosion resistance properties, stainless steel has been used in roofing for industrial and commercial properties for decades. But over time, it has slowly been becoming a popular roofing material for residential properties. Due to its sleek, modern appearance, stainless steel can provide a great look to your home along with robust protection against the elements.
Advantages
👉 Stainless steel metal roofs are highly durable and can survive around 50 years with proper care.
👉 It is cost-effective compared to other corrugated metal roofing systems. It is also comparatively easy to install, making it cheaper than other metals.
👉 It is widely available in multiple colors and sizes, allowing you to choose according to your aesthetic and design preferences.
Disadvantages
👉 Steel is much heavier than aluminum or other metals, which can put pressure on the structure of your home.
👉 The iron content in steel makes it very sensitive to water and rusting, so it might need regular inspections and protective coatings to prevent damage.
👉 Even though it is a strong metal, stainless steel is still more susceptible to dents if heavy objects like tree limbs hit it.
Installation Cost
Stainless steel corrugated roofing systems typically cost between $10 and $20 per square foot, depending on the thickness, coatings, installation requirements, and geographical location.
Weather Considerations
Steel is highly resistant to extreme weather conditions, including high winds and heavy snow loads. However, in coastal areas with salt exposure, galvanized steel is often preferred due to its superior corrosion resistance.
Aluminum Corrugated Roofing System
Aluminum is a lightweight, corrosion-resistant metal widely popular in coastal regions or areas with high humidity.
Specifications and Needs
Aluminum roofing panels are lightweight, which makes them easy to transport and install. Aluminum naturally resists rust and corrosion without needing additional coatings. It’s commonly available in gauges between 22 and 29, with lower gauges being more durable but expensive.
Advantages
👉 Aluminum is naturally corrosion, dust, and water-resistant, ideal for coastal environments.
👉 It is also very lightweight, so it does not strain the structure of your home, and is very easy to install.
👉 It is highly reflective, reducing heat absorption and energy costs in warmer climates.
Disadvantages
👉 It is not as strong or durable as steel, making it more prone to dents from heavy impacts.
Installation Cost
Aluminum roofing panels typically range from $4 to $11 per square foot.
Weather Considerations
Aluminum performs exceptionally well in coastal and humid environments, where saltwater or moisture can cause other metals to rust. Due to its reflective properties, it’s also great for hot climates.
Copper Corrugated Roofing System
Copper roofs are known for their distinct appearance and long lifespan. Over time, a copper roof will develop a natural patina that gives it a greenish hue.
Specifications and Needs
Copper is usually used in high-end residential or historic buildings. It’s incredibly durable and can last over 100 years with minimal maintenance. Copper is also mouldable, making it easy to shape around curves and architectural features.
Advantages
👉 Copper corrugated metals can survive any climate and weather conditions for over 100 years.
👉 As it ages, the roof develops a beautiful patina, which can provide an unusual yet pleasant aesthetic look to your home.
👉 Due to its highly resistant features, copper requires little maintenance.
Disadvantages
👉 Copper is costly to extract as a raw material, ultimately increasing its price. Copper roofs are one of the most expensive options on the market.
👉 Compared to other metal roofing systems, copper is delicate and soft. If not installed properly, it can get damaged with the slightest dent.
Installation Cost
The final installation price of a copper roofing system can range from $15 to $32 per square foot, depending on the thickness of the material and installation fees.
Weather Conditions
Due to its self-healing properties, copper is considered an excellent choice for all weather conditions. However, its costly price tag makes it less affordable for properties on a budget.
Zinc Corrugated Roofing System
Zinc is an environmentally friendly roofing material known for healing from scratches and maintaining a beautiful finish for decades.
Specifications and Needs
Zinc is highly malleable, making it ideal for unique architectural designs. Over time, its natural zinc carbonate coating forms to protect the metal from rust and weathering.
Advantages
👉 The self-healing properties of zinc make it immune to corrosion and scratches, which saves a lot of money on repairs and replacements.
👉 Much like copper, zinc is a very durable metal that can survive for 100 years.
👉 Zinc is 100% recyclable, making it a more environmentally friendly roofing system than others.
Disadvantages
👉 Due to its limited availability, zinc is more expensive than other metals, though it’s still cheaper than a copper roof.
👉 Over a decade after the installation, the appearance of the coating might change due to exposure to pollution and moisture.
Installation Cost
Zinc, like copper, is considered an expensive metal compared to other roofing materials. It is also a softer option, so the installation may cost between $6 and $18 per square foot.
Weather Considerations
Zinc is highly durable in both hot and cold climates, and it can expand and contract without warping. Its natural weather-resistant properties make it a good choice in areas with frequent rain or snow.
Galvanized Steel Corrugated Roofing System
A galvanized steel roof is one of the most common and reliable choices for homeowners looking for a durable and cost-effective roofing material. Made of steel sheets coated with a protective zinc layer, galvanized roofs are immune to rust and corrosion. These sheets are used in both commercial and residential properties as a popular roofing solution.
Specifications and Needs
The zinc coating ensures long-lasting protection against weather elements like rain and snow. This makes it an ideal choice for homeowners living in areas with moderate climates.
Advantages
👉 Galvanized sheets are rust-resistant and corrosion-free.
👉 It is more affordable and comes with a balance of durability and cost-effectiveness, even after its installation.
Disadvantages
👉Even though it is rust-resistant, over time, galvanized steel can rust due to excessive water or snow damage.
👉 Galvanized steel isn’t scratch-proof and can develop rust if scratched deeply.
Installation Cost
A galvanized roofing system typically costs between $5 and $12 per square foot installed.
Weather Considerations
Galvanized sheets perform well in various climates, though it’s especially suitable for areas with high moisture or humidity. It’s less likely to rust than stainless steel, making it a good option for frequent rain or snow areas.
