4 TYPES OF METAL ROOFING MATERIALS

Metal roofing, once a feature exclusive to high-end, architecturally designed homes, has now gained widespread popularity in residential housing of various styles. The appeal of metal roofing extends beyond its enhanced durability and longer lifespan compared to traditional asphalt roofs. These roofs are not only built to last but also add aesthetic value, significantly enhancing the visual appeal of homes. Innovatively designed, some metal roofs are even crafted to mimic the appearance of shingles, offering the resilience of metal while retaining a traditional aesthetic. This blend of functionality and beauty makes metal roofing a versatile choice for a wide range of residential properties.

FOUR OF THE MOST COMMON MATERIALS USED IN METAL ROOFING

When selecting a metal material for roofing, you have a variety of choices, each with its unique benefits and characteristics. The most commonly used metals include aluminum, copper, stainless steel, and zinc. These materials vary in popularity based on factors like cost, durability, and aesthetic appeal. In the following section, we will delve into these four prevalent types of metal roofing, exploring their distinct properties and why they might be chosen for a roofing project.

ALUMINUM

Aluminum, being the third most abundant metal on Earth, is an excellent choice for residential construction, especially in the roofing industry. Its abundant availability makes it a readily accessible and sustainable option for roofing materials, contributing to its popularity in home construction.

Advantages of Aluminum Roofing:

Corrosion Resistance: Aluminum’s rapid reaction to atmospheric conditions makes it exceptionally resistant to corrosion, ideal for coastal areas with salty air.
Lightweight and Durable: Its light yet strong nature makes aluminum suitable for residential roofing. It’s also recyclable and energy-efficient, adding to its sustainability.
High Recyclability: Approximately 90-95% of aluminum roofing can be recycled, underscoring its environmental friendliness.
Versatility in Design: Aluminum’s malleability allows it to be crafted into various styles, including those that resemble shingles, stone, or clay.
Longevity: Aluminum roofs are rust-proof, contributing to an extended lifespan.
Availability: This material is widely accessible and familiar to roofing contractors.

Disadvantages of Aluminum Roofing:

Susceptibility to Dents: Aluminum’s softer nature makes it more prone to denting.
Higher Cost: While offering superior corrosion resistance, aluminum is generally more expensive than other metal roofing options.
Color Fading Over Time: With age, aluminum may lose its color, becoming washed out or spotty. This can be mitigated by opting for resin-coated roofing coils or panels.

Cost Considerations:

The price of aluminum roofing varies with market fluctuations and typically falls between the cost of steel and copper roofing.

COPPER

Copper is often revered as the traditional choice in metal roofing, having been utilized globally for centuries. In the right conditions, copper roofing can remarkably last upwards of 200 years. Its longevity and classic aesthetic make it a favored choice for a variety of structures, including churches, significant architectural buildings, commercial properties, and occasionally as an accent feature in residential homes. This extensive historical use and the ability to endure for centuries underscore copper’s enduring appeal and reliability in roofing.

Advantages of Copper Roofing:

Exceptional Durability: Copper roofs are renowned for their longevity, often lasting for several decades and, in some instances, even centuries.
Lightweight Nature: Copper is lighter than many other metal roofing materials, making it easier for installation and reducing structural stress on buildings over time.
Energy Efficiency: Like other metal roofs, copper is energy-efficient, potentially leading to savings on energy costs.
Aesthetic Appeal: Copper roofs enhance a building’s exterior with their unique, striking appearance, serving as an eye-catching architectural feature.

Disadvantages of Copper Roofing:

High Cost: Among metal roofing options, copper is typically the most expensive due to its durability and aesthetic qualities.
Patina Formation: Over time, copper reacts with oxygen to form a green patina. While some appreciate this look, others may find it less desirable.
Thermal Expansion and Contraction: Copper can expand and contract with temperature changes, requiring specific installation techniques, like appropriate panels or shingles, to manage this movement.

Cost Implications:

Copper roofing, given its superior longevity and aesthetic qualities, is generally the most expensive metal roofing option available.

STEEL

Steel stands out as a popular choice in metal roofing due to its affordability. It is available in three primary varieties: galvanized, galvalume, and stone-coated steel. Each type offers unique characteristics:

Advantages of Steel Roofing:

Cost-Effectiveness: Steel roofing is among the more budget-friendly options compared to other metal roofing materials.
Durability and Strength: Known for its robustness, steel roofing resists rust and can withstand impacts like hail, making it a long-lasting choice.
Color Variety: Available in a broad range of colors, steel roofing offers flexibility in matching different architectural styles.
Environmentally Friendly: Steel is both highly recyclable and readily available, making it an eco-conscious roofing option.

Disadvantages of Steel Roofing:

Potential for Corrosion: While sturdy, steel roofing can be prone to corrosion, but this can be mitigated with the use of specialized metal roofing paints.
Possibility of Shorter Lifespan: Without proper installation and regular maintenance, steel roofs may not last as long as other metal roofing options.

Cost Considerations:

In terms of pricing, steel roofing generally stands as the most economical and accessible choice in the realm of metal roofing materials.

ZINC

Zinc is a type of metal roofing material recognized for its durability and longevity. Its popularity in the United States has been on the rise in recent years, largely due to its ease of use, exceptional resistance to corrosion, and various sustainable attributes.

Advantages of Zinc Roofing:

Abundant Availability: Zinc, being the 23rd most abundant element in the Earth’s crust, is readily accessible for roofing projects.
Impressive Lifespan: Zinc roofs are known for their longevity, typically lasting 60-100 years, and in some cases, up to 150 years. This duration depends on factors like climate, installation quality, and building characteristics.
Environmentally Friendly: As a natural metal extracted from the ground, zinc has low toxicity levels, reducing concerns about toxic run-off from roofing.
Energy Efficiency: Zinc roofs reflect solar heat, unlike traditional tile or shingles, which can help in reducing energy costs.

Disadvantages of Zinc Roofing:

Higher Initial Cost: Zinc is one of the pricier options for metal roofing, although its extended lifespan and lower maintenance needs can offset the initial investment.
Potential for Underside Corrosion: If not properly coated, the underside of zinc panels may experience corrosion.

Cost Overview:

Zinc ranks among the more costly metal roofing materials. Its price ranges from $600 to $900 per square, reflecting its quality and durability.

FAQs ABOUT METAL ROOFING

Is a Metal Roof Noisy During Rain?

Contrary to common belief, metal roofs are not excessively noisy during rain. In residential installations, a sturdy layer of sheathing is placed between the metal roof and the existing structure, significantly dampening any sound. Often, you might not even realize it’s raining unless you see it.

Can I Install Skylights on a Metal Roof?

Absolutely, skylights can be installed on metal roofs just like on any other roofing material. However, consider the following:

The ideal time for skylight installation is during roof installation or replacement, rather than retrofitting on an existing roof.
While metal roofs can be quiet during rain, soundproofing skylights is more challenging. In areas with frequent rainfall, this might be a consideration.
Skylights can affect the energy efficiency of your home by altering heat gain and loss.

Will a Metal Roof Blend in With My Neighborhood?

Metal roofing can be distinct in a neighborhood predominantly featuring asphalt shingles. But the good news is, modern metal roofs offer versatile aesthetics. They can be designed to mimic the look of asphalt shingles, slate, cedar, and more, allowing for harmonious integration with your neighborhood’s style.
