Why is Galvalume Steel the Top Choice for Metal Roofing?

When it comes to selecting roofing materials, durability, efficiency, and longevity are essential factors. Galvalume steel has become a preferred choice for many homeowners and contractors due to its superior performance and longevity. Combining the strengths of aluminum and zinc, galvalume steel is widely used in metal roofing. At MC Roofing Services, we utilize galvalume steel extensively for its numerous benefits and exceptional qualities.

Composition of Galvalume Steel

Galvalume steel is created by coating a carbon steel sheet with an alloy consisting of 55% aluminum and 45% zinc. This unique combination results in a product that provides enhanced corrosion resistance compared to traditional galvanized steel, which is coated solely with zinc. The aluminum in the coating protects the steel from oxidation, while the zinc provides additional barrier protection and ensures the cut edges remain protected.

Benefits of Galvalume Steel

Corrosion Resistance

One of the most significant advantages of galvalume steel is its corrosion resistance. The aluminum-zinc alloy coating is a protective barrier, preventing the steel from rusting. This makes galvalume steel particularly suitable for environments prone to moisture and humidity, ensuring the roof remains intact and functional for decades.

Heat Reflectivity

Galvalume steel’s reflective properties help in reducing heat absorption. This is particularly beneficial in warmer climates, as it helps keep buildings cooler and reduces the need for air conditioning. By reflecting a significant portion of the sun’s rays, galvalume steel contributes to energy efficiency and lower utility bills.

Longevity and Durability

Galvalume steel roofs are known for their longevity and durability. With proper maintenance, these roofs can last over 50 years. The combination of aluminum and zinc provides a robust layer of protection, ensuring the roof withstands harsh weather conditions, including heavy rain, strong winds, and hail.

Uses of Galvalume Steel in Metal Roofing

Residential Applications

Galvalume steel is a popular choice in residential settings due to its sleek appearance and long-lasting protection. It is used in various architectural styles, providing a modern and clean look. Homeowners appreciate the minimal maintenance requirements and the extended lifespan that galvalume steel offers.

Commercial Applications

Commercial buildings often use galvalume steel for roofing due to its durability and cost-effectiveness. The material’s ability to withstand severe weather conditions and its energy-efficient properties make it ideal for large commercial projects. Additionally, galvalume steel’s fire resistance is an added advantage for commercial properties.

Industrial Applications

Industrial facilities benefit from galvalume steel’s resistance to harsh environmental conditions. Whether exposed to chemicals, pollutants, or extreme temperatures, Galvalume steel roofs provide reliable protection. The material’s strength and resilience ensure that industrial buildings remain secure and operational.

Installation and Maintenance

Installation Process

Installing galvalume steel roofing involves several steps to ensure optimal performance. It starts with preparing the roof deck, followed by placing the underlayment. The galvalume steel panels are then installed, starting from the bottom edge of the roof and working upwards. Proper alignment and secure fastening are crucial to prevent leaks and ensure durability.

Tips for Maintenance and Care

Maintaining a galvalume steel roof is relatively straightforward. Regular inspections should be conducted to check for any signs of wear or damage. Cleaning the roof to remove debris, dirt, and organic matter is essential to prevent potential issues. It’s also important to check for and replace any damaged panels or fasteners promptly.

Comparison with Other Roofing Materials

Advantages of Traditional Roofing Materials

Galvalume steel offers several advantages over traditional roofing materials like asphalt shingles and wood. Its superior corrosion resistance, durability, and energy efficiency make it a better choice for long-term performance. Additionally, galvalume steel’s reflective properties help in maintaining cooler indoor temperatures, reducing the need for air conditioning.


While the initial cost of galvalume steel may be higher than some other materials, its long lifespan and minimal maintenance requirements make it cost-effective in the long run. Homeowners and businesses can save on repair and replacement costs, as well as energy bills, making galvalume steel a wise investment.

Environmental Impact

Recyclability of Galvalume Steel

Galvalume steel is 100% recyclable, making it an environmentally friendly roofing material. The steel can be recycled and repurposed at the end of its life cycle, reducing the environmental footprint. This contributes to sustainable building practices and helps conserve natural resources.

Energy Efficiency Benefits

The reflective properties of galvalume steel contribute to energy efficiency by reducing the amount of heat absorbed by the building. This lowers the demand for air conditioning, resulting in lower energy consumption and reduced greenhouse gas emissions. Using galvalume steel supports efforts to create energy-efficient buildings and reduce overall energy costs.


Galvalume steel is a versatile and highly effective material for metal roofing, offering numerous benefits such as corrosion resistance, heat reflectivity, and durability. Whether used in residential, commercial, or industrial applications, galvalume steel provides reliable protection and long-term value.
