With its raised seams, this style of metal roofing can offer excellent water resistance, minimizing the risk of water penetration. The standing seam profile provides a clean and modern appearance to homes. This style is architecturally versatile and is suitable for contemporary and traditional designs.


Corrugated panels feature a series of parallel ridges and grooves, creating a distinctive wavy pattern. This type of metal roofing is lightweight and cost-effective and provides good water drainage due to its corrugated design. Corrugated metal roofing offers a traditional and industrial appearance and is often used in agricultural and industrial settings.

Metal Shingles or Tiles

Metal shingles or tiles mimic the appearance of traditional roofing materials like asphalt or wood shingles. This style of metal roofing provides durability and longevity and offers a classic and upscale aesthetic. Metal shingles or tiles are usually lightweight and easy to install.

Durability and Longevity

Metal roofs are considered durable due to several inherent characteristics that contribute to their longevity and resilience. Many metal roofing materials, such as aluminum, zinc, and copper, exhibit natural corrosion resistance. Coatings, such as galvanization and special finishes, provide additional protection against corrosion. Certain metals, like zinc, possess self-healing properties. Over time, zinc can develop a protective layer that helps repair small scratches or imperfections.

Metal roofs are generally strong and tough, with the ability to withstand impact from hail, debris, and extreme weather conditions. Resistant to elements like fire, wind, and now, metal roofs do not rot, warp, or become susceptible to issues like mold or mildew.

The expected lifespan of different metal roofing materials can vary based on factors such as material composition, coating, installation quality, and environmental conditions. Metal roofing materials, such as steel, aluminum, and tin, have an expected lifespan of 40 to 70 years. Some roofing materials, like copper and zinc, can last over 70 years.

Energy Efficiency

Metal roofs possess several energy efficient properties that positively impact energy savings.


Metal roofs, especially those with light-coloured or reflective finishes, have high reflectivity. This reflectivity helps reduce the absorption of solar heat, keeping the roof surface cooler. This, in turn, contributes to lower indoor temperatures and reduced cooling costs.


Emissivity measures a material’s ability to release absorbed heat. Metal roofs often have high emissivity, allowing them to radiate heat efficiently. High emissivity facilitates the quick release of absorbed heat, preventing the roof from retaining excessive warmth and contributing to energy savings.

Cool Roofing Technology

Some metal roofing systems are designed as “cool roofs,” incorporating technology that enhances reflectivity and emissivity. Cool roofing technology maximizes the roof’s ability to reflect sunlight and release absorbed heat, reducing the overall heat gain in the building and lowering cooling requirements.

Metal roofs are also compatible with various insulation materials that further enhance energy efficiency. Furthermore, metal roofs can often support the installation of solar panels. With solar panels, homeowners can generate renewable energy and reduce their dependence on conventional energy sources. By leveraging these energy efficient properties, metal roofs contribute to lower energy consumption, reduced energy bills, and a more sustainable and environmentally friendly approach to building design.

Installation Considerations

When it comes to metal roofing, professional installation is crucial for successful performance and longevity. Metal roofs have specific installation requirements, including correct fastening methods, spacing, and flashing details. Professional installers have the expertise to follow manufacturer guidelines and industry best practices, preventing mistakes that could compromise the roof’s integrity. Professional installers are trained to properly seal seams, edges, and penetrations, ensuring a watertight roofing system. They also ensure adequate ventilation to prevent issues such as moisture buildup and attic heat retention. Professional installation enhances the performance of the roof and contributes to its long-term durability.

Maintenance Requirements

Compared to other roofing materials, metal roofs are generally considered low maintenance. However, it is important to conduct periodic maintenance to ensure optimal performance and longevity. Here are some maintenance requirements for metal roofs:

Regular Inspections

Conduct visual inspections to check for signs of damage, loose fasteners, or areas that may need attention. Look for debris buildup and inspect flashing. This type of inspection can be done annually or biannually.

Gutter Cleaning

Clean gutters and downspouts to prevent debris accumulation. Ensure proper drainage to avoid water backups. Gutter cleaning can be done seasonally or as needed.

Coating Inspection

If the metal roof has a protective coating, inspect it for wear and deterioration. Depending on the coating type, this inspection can be done every 5 to 10 years. Reapply coatings as recommended by the manufacturer.

Professional Inspection

Schedule a professional inspection to assess the overall condition of the roof, including seams, flashing, and potential issues that may require expert attention. This can be done every 5 to 10 years or as needed.

Homes in harsh climates or areas prone to severe weather may require more frequent inspections and maintenance. Older roofs may also require more frequent maintenance, as wear and tear accumulate over time. By following a regular maintenance schedule and addressing issues promptly, homeowners can ensure their metal roofs remain in good condition and continue to provide long-lasting protection for their homes.

Cost Considerations

The costs associated with purchasing and installing a metal roof can vary based on several factors, including the type of metal, the roofing system’s complexity, and the local market.
