More homeowners — particularly in hurricane-prone areas — are choosing metal roofing over asphalt shingles and other materials, and for good reason. Metal roofing is durable, energy-efficient, and can withstand severe weather. 

    However, “metal roofing” is a general term for a variety of different alloy types, each with its own unique characteristics. If you’re considering a new metal roof for your home, it’s important to know the differences to make an informed decision.

    To compare the price of a metal roof to other types of roofs, check out our guide on metal roofing costs.

    If you’re ready to learn more about the different types of metal roofs, keep reading. Here are four popular metal roofing options and what you should know about each of them.


    1. Steel

    Steel is known for its strength and durability as a building material, but it’s also great for roofing. Made primarily from iron, steel can withstand severe impacts from hail, high winds, heavy snow, and ice accumulation. Steel roofing comes in many colors and coatings, with popular options being galvanized and Galvalume™. Galvanized steel’s zinc coating protects the steel from corrosion, while Galvalume™ uses both aluminum and zinc to protect the steel.

    Strength, style, and energy efficiency attract many homeowners to steel. Quality steel roofing resembles clay tile, shakes, or slate, and it can last 50+ years depending on installation and regional weather. Steel is also the most recycled material on the planet, making it a very environmentally friendly metal roofing choice.

    In terms of weather protection, steel roofing resists damage from hail storms and hurricane-force winds without denting. Steep-slope steel roofing can withstand winds up to 140 mph, providing peace of mind for coastal homeowners. The interlocking panels are designed to stay intact even during high winds.

    Compared to other metals, steel has very high tensile strength. This strength allows steel roofing to safely support any accumulated snow loads over the winter without buckling or collapsing. While steel can develop rust over time, the protective zinc and aluminum-zinc coatings provide an extra layer of defense against corrosion. This greatly extends the life span of the roof.

    Steel roofing can also enhance the curb appeal and resale value of your home. The material is available in many colors. The deep color saturation and matte finish help steel roofing complement both traditional and contemporary home styles.


    2. Copper

    Copper roofing is prized for its eye-catching, timeless beauty. However, it also comes at a high up-front cost compared to alternatives due to higher demand and limited supply.

    As a metal, copper reflects heat rather than absorbing it. So, when properly assembled and ventilated, copper roofs can boost the energy efficiency of your home. Over time, aged and weathered copper transitions in appearance, developing a patina. This distinctive patinated look caused by natural oxidation is desirable for architectural aesthetics. The rate of patina development depends on environmental factors like air pollution and rainfall.

    Copper’s natural compounds can speed up corrosion in neighboring metals. So, copper roofing should be isolated and not used alongside other metal materials. Homeowners should work with an experienced copper installer familiar with proper isolation installation techniques.

    For more information, read about average copper roof pricing and research contractor rates in your area.

    While copper roofing comes with a steep up-front investment, it is arguably the most durable and longest-lasting metal roofing material. When properly installed, a copper roof can realistically last 80–100 years before needing replacement. This exceptional life span means copper roofing may actually be more cost-effective in the long run. Many other roofing materials need to be replaced every 20 or 30 years.

    The malleable properties of copper allow it to slowly expand and contract over seasons and years without cracking, splitting, or leaving gaps. This quality makes copper an ideal choice for homeowners with historic homes and unique architectural styles. Copper is also lightweight, so it’s perfect for homes and structures where a heavy roofing material would be problematic.

    One potential downside to copper roofing is the possibility of bluish-green runoff as the copper corrodes over decades of exposure to the elements. Your roof requires proper maintenance and sealing to prevent copper corrosion residues from causing environmental problems.


    3. Aluminum

    Aluminum is prized for its corrosion resistance, making it a top choice for seaside climates. Cost-wise, aluminum roofing falls somewhere between steel and copper.

    The durability of aluminum comes from its natural ability to resist corrosion. When exposed to oxygen, aluminum undergoes a chemical process that creates a thin oxidized layer on its surface. This protective aluminum oxide layer seals the inner metal layers from further corrosion.

    High-quality aluminum roofing panels have an optimal strength-to-weight ratio and a thicker profile than steel. This thick profile gives aluminum superior durability and dent resistance for coastal areas prone to extreme weather from hurricanes.

    Like copper, aluminum develops a patina over time as it undergoes natural weathering processes. However, many homeowners opt to coat aluminum roofing with durable paint or sealants in their preferred color. This coating maintains the roof’s original appearance for longer as opposed to letting the randomized patina develop.

    For seaside climates constantly exposed to ocean air and salt spray, aluminum is one of the most corrosion-resistant metal alloys available. An aluminum roof can easily last 40–60 years in coastal conditions before you need to replace it.

    On the downside, uncoated and unsealed aluminum will naturally ‘chalk’ over time when exposed to the elements. This leaves a light dusty residue on the roof’s surface. Proper maintenance, like occasional power washing, can remove chalking and keep an aluminum roof looking brilliant.


    4. Zinc

    Zinc roofing stands out for its sustainability and durability compared to other material options:

    • Production requires far less energy than copper or steel
    • The low melting point of zinc enables centuries of reliable performance
    • Zinc is 100% recyclable at the end of its life span

    The pliable, moldable nature of zinc makes it easy to form and manipulate. This allows for more flexible and unique roof designs. In terms of cost, zinc is comparable to premium copper roofing. Like copper, zinc develops its own patina over time as it weathers and reacts to environmental factors.

    Minor zinc roof scratches will self-heal and fill back in over time. However, the material is prone to a layered, whitish, chalky buildup in areas where water collects and flows.

    Protective sealants are a must for zinc roofs. It’s also important to work with an installer who has expertise in proper zinc roof installation and maintenance.

    Thanks to its natural resistance to corrosion, zinc roofing can achieve exceptional longevity when properly installed. A zinc roof will easily last over 100 years before it needs replacement. It’s important to consider how long a roof lasts, and zinc roofing is just about the best of the best when it comes to longevity.

    The softness and flexibility of zinc allow it to be pressed and folded into decorative, ornamental roof profiles. Homes with complex rooflines, turrets, domes, and other unique architectural elements are perfectly suited for zinc roofing. Contractors can work zinc into custom shapes and details to complement these designs.

    Proper maintenance for zinc roofs includes annual inspections and reapplication of protective sealants to prevent chalking buildup and oxidation over the years. While pricy at initial purchase like copper, the exceptionally long life span of zinc roofing provides great value over time.


    So, Is Metal Roofing Right for Your Home?

    When it’s time to replace your roof, you’ll need to consider several factors beyond just the roofing material itself. Think about your home’s architectural style, local climate patterns, lifetime budget, and your personal preferences around esthetics and maintenance.

    Overall, metal roofing provides durability, longevity, dent resistance, and weather protection that far outperforms traditional shingle or tiles. Metal roofing styles are available to complement homes from classic to contemporary, and the sustainability of metal roofing makes it an eco-friendly choice.

    If you live in an area prone to extreme weather, a metal roof might even lower your home insurance rates.
