How metal roofs perform in snowy conditions

Metal roofs have gained popularity due to their durability, longevity, and energy efficiency. However, one concern homeowners have is how they perform in snowy conditions. Here, we will discuss the performance of metal roofs in snowy conditions, addressing various factors such as snow retention, structural integrity, and energy efficiency.

However, before we go into the performance of metal roofs in snowy conditions, here's an overview of the different types of metal roofs. Let's dive in!

Types of Metal Roofs

Metal roofs have become widespread in recent years due to their durability, longevity, and energy efficiency. There are various types of metal roofs available in the market, with each offering unique benefits and properties. Here are the most common types of metal roofs to help you decide which one is the right choice for your home or building.

Standing seam metal roofing

Standing seam roofing is one type of metal roofing that is quickly becoming popular. It consists of vertical panels with raised seams that interlock to provide a watertight cover for your roof.

This type of roof offers excellent durability and weather resistance, as the vertical design prevents water from seeping through the roof. Additionally, standing seam metal roofing is known for its sleek and modern appearance, making it a popular choice for contemporary buildings.

Corrugated metal roofing

Corrugated metal roofing features repetitive grooves that run vertically along the panels. This type of roof is commonly seen in industrial and agricultural settings due to its affordability and ease of installation. Corrugated metal roofing is highly durable and can withstand adverse weather conditions, making corrugated metal roofing ideal for areas with heavy rainfall or strong winds.

Metal shingles

Metal shingle roofs are designed to resemble traditional roofing materials like wood shakes, asphalt shingles or slate. They offer the benefits of metal roofing while maintaining a more traditional and aesthetically pleasing appearance.

Metal shingles are available in various colors and styles, allowing homeowners to customize their roofs to match their desired look. Moreover, they provide excellent durability, energy efficiency, and fire resistance.

Metal tiles

Like metal shingles, metal tiles are specifically manufactured to mimic the look of more conventional roofing materials like Spanish clay tiles or ceramic tiles. Metal tiles offer the same benefits as other metal roofs, including durability, longevity, and energy efficiency. They are lightweight, easy to install, and come in various styles and colors to suit any architectural style.

Copper roofing

Copper roofing is renowned for its distinctive appearance and natural patina. Over time, copper roofs develop a striking greenish-blue hue, adding a bit of elegance to any building.

In addition to their timeless aesthetic appeal, copper roofs are incredibly hardy and can last over a century. They are also highly corrosion-resistant, making them ideal for coastal areas with high salt content in the air.

Zinc roofing

Zinc roofing is admired for its unique shade of blue-gray that matures beautifully over time. It is a low-maintenance choice that requires minimal treatment or coating. Zinc roofs are also highly corrosion-resistant and can last for several decades. Moreover, zinc is a sustainable material and can be recycled at the end of its lifespan, making it an eco-friendly choice.

Aluminum roofing

Aluminum roofing is lightweight, durable, and corrosion-resistant, making it suitable for various climates. It is a highly malleable material, allowing for easy customization and versatility in design. Aluminum roofs are available in a wide range of colors and finishes, ensuring that homeowners can find a style that complements their property.

Steel roofing

Steel roofing is a cost-effective option that offers excellent durability and weather resistance. It is available in different gauges, with thicker gauges providing added strength and protection against extreme weather conditions. Steel roofs are also highly fire-resistant, making them a reliable choice for areas prone to wildfires.

Metal roofs come in copious types, each with its own unique features and benefits. Whether you prefer the sleek and modern look of standing seam metal roofing or the timeless charm of copper or zinc roofs, there is a metal roof option to suit every homeowner's needs and preferences.

When considering a metal roof, consult with a professional roofing contractor to determine which type will best meet your requirements for durability, aesthetics, and budget.

How Metal Roofs Perform in Snowy Conditions

With everything above, let us now go deeper into the performance of metal roofs when subjected to snowy conditions. Here's what you should know:

Snow retention

One advantage of metal roofs is their smooth surface, which allows snow to slide off easily. This minimizes the risk of snow accumulation and prevents excessive load on the roof. However, some metal roofs can be designed with snow retention systems, such as snow guards or snow stops, to prevent large amounts of snow from sliding off at once. These systems break up the snowslide into smaller sections, reducing the impact and potential damage.

Structural integrity

Metal roofs are well-known for their strength and durability, making them well-suited to withstand heavy snow loads. Depending on the design and materials used, metal roofs can typically hold up to 25-30 pounds of snow per square foot.

This load capacity can vary between different types of metal roofing, so it's essential to consult with an experienced and licensed roofing contractor to determine the appropriate metal roof for your specific snow loads.

Preventing ice dams

Ice dams are a common issue in snowy conditions, where heat from the attic melts the snow on the roof, leading to refreezing at the eaves. This refreezing creates a dam that can cause water to back up under the shingles, potentially leading to leaks and water damage. Metal roofs have a high thermal conductivity, allowing for consistent cooling of the roof surface, which helps prevent the formation of ice dams.

Energy efficiency

While metal roofs have a good track record in snowy conditions, they also offer excellent energy efficiency. The metal reflects sunlight, reducing heat absorption and keeping the roof cooler during hot summer months.

This can help prevent excessive snow melting and refreezing, reducing the risk of ice dams. Additionally, metal roofs can be designed with proper insulation and ventilation systems to minimize heat loss during winter, resulting in lower energy bills and a more comfortable living space.

Installation considerations

When installing a metal roof in snowy conditions, certain factors need to be considered. Firstly, proper sealing and insulation are crucial to prevent heat transfer and maintain the roof's temperature. This prevents ice dam formation and ensures the roof surface remains cold enough to support snow accumulation without excessive melting.

Secondly, it's essential to choose a metal roofing material suitable for your specific climate. Some metals have better resistance to corrosion and damage in snowy conditions, such as galvanized steel or aluminum. Consult a licensed professional roofer who can recommend the correct type of metal roofing for your area.

Maintenance and snow removal

Metal roofs typically require minimal maintenance, but regular inspections are recommended, especially after heavy snowstorms. Check for any damage or stress on the roof surface, such as bent or broken panels, which could result from heavy snow loads. Additionally, it's essential to practice safe snow removal techniques, such as using plastic shovels or roof rakes, to avoid causing any damage to the metal surface.

Metal Roofing is Great for Snow and Ice Conditions

Metal roofs perform exceptionally well in a snowy country. Their smooth surface helps snow slide off easily, reducing the risk of excessive snow accumulation. Metal roofs also have the structural integrity to withstand heavy snow loads, preventing damage to your home.

Additionally, they can help prevent ice dams and offer excellent energy efficiency. By working with experts to find the right type of metal roofing and following proper roof installation and maintenance practices, homeowners can enjoy the many benefits of metal roofing in winter.
