Types of Metal Roofing
Metal roofing offers a durable, long-lasting, and energy-efficient solution for residential and commercial buildings. With various materials and styles available, choosing the right metal roof depends on budget, aesthetic preferences, and performance needs. Here's a comprehensive overview of the most common types of metal roofing materials and styles used for homes.
Metal Roofing Materials
Steel
Steel is the most commonly used metal roofing material due to its strength and affordability. It is heavier than aluminum but highly durable. Steel roofs are typically coated with zinc (galvanized) or a zinc-aluminum alloy (Galvalume) to protect against rust and corrosion. Over this, an epoxy primer and acrylic paint finish are applied for color and additional protection. Steel roofs can last several decades when properly maintained.
Aluminum
Aluminum is lightweight, naturally rust-resistant, and ideal for coastal or humid environments. It requires fewer protective coatings than steel but is softer and more prone to dents. Aluminum roofing is available in multiple styles, including standing seam, corrugated panels, and shingles. It reflects heat well, improving energy efficiency.
Zinc
Zinc roofing is highly durable and environmentally friendly. It develops a natural protective patina (zinc-hydroxyl-carbonate) that guards against moisture and corrosion. Zinc is malleable, allowing it to fit complex roof shapes. Although less common in the U.S., zinc roofs are popular in Europe for their longevity and sustainability.
Copper
Copper is a premium roofing material famous for its longevity, often lasting over 100 years. It requires no coatings or finishes and develops a distinctive green patina over time. Copper roofs are easy to work with, resistant to corrosion, and offer a unique aesthetic, though they come with a higher upfront cost.
Alloy
Metal alloys combine different metals to create strong, durable roofing materials. Alloy roofs are designed to weather beautifully and provide long-term protection similar to copper, but often at a lower cost.
Stainless Steel
Stainless steel roofing is among the most durable and corrosion-resistant options available. It is coated with terne to give a matte-gray finish that lasts a lifetime. While expensive, stainless steel roofs offer exceptional longevity and minimal maintenance.
Metal Roofing Styles
Standing Seam
Standing seam metal roofs consist of long, vertical panels joined by raised seams that interlock. Fasteners are concealed beneath the seams, providing a sleek appearance and superior weather tightness. This style is highly durable, energy-efficient, and compatible with solar panel installation. It is popular for residential and commercial buildings but is more expensive and needs professional installation.
Corrugated Metal
Corrugated metal roofs feature wavy, ridged panels that add structural strength. Commonly made from galvanized steel or aluminum, corrugated roofs are cost-effective and strong, often used for agricultural, industrial, and residential applications. They have exposed fasteners and an industrial look, which may not suit all home styles.
R-Panel
R-panel roofs are made from heavy-duty steel and have trapezoidal ribs spaced twelve inches apart. They are durable, low-maintenance, and can be installed over existing shingles, reducing labor and disposal costs. R-panels are popular for commercial and agricultural buildings but can also be used in residential settings.
U-Panel
U-panels are heavier gauge steel panels with a distinct rib profile, offering extra strength and durability. Like R-panels, they can be installed over existing roofing materials and are favored for commercial and industrial use.
AP Panel
AP panels mimic the look of standing seam roofs but at a lower cost. They require the removal of old shingles before installation and are designed for new construction or full roof replacements. AP panels provide good durability and aesthetic appeal for residential and commercial buildings.
CF (Concealed Fastener) Panel
CF panels feature a locking system that hides fasteners for a clean, smooth appearance. This style combines aesthetic appeal with long-lasting color retention and weather resistance, making it ideal for homeowners seeking a modern, sleek metal roof.
Stone-Coated Metal Roofing
Stone-coated metal roofs are steel panels coated with stone granules, replicating the look of traditional roofing materials like asphalt shingles or slate. They offer the durability of metal with a classic appearance and are popular for homeowners wanting a traditional look with the metal's longevity.
Stamped Metal
Stamped metal roofing mimics the appearance of tile, slate, or shake by pressing metal panels into decorative shapes. This style combines metal's durability with the aesthetic of more traditional roofing materials.
Layers of a Metal Roof
A typical metal roof system includes:
Roof deck (plywood or OSB)
Underlayment (synthetic or felt paper for moisture barrier)
Metal panels or shingles (steel, aluminum, copper, etc.)
Fasteners and clips (concealed or exposed)
Flashing (around chimneys, vents, and edges)
Ridge caps and trim for finishing
Choosing the Best Metal Roofing for a Home
Selecting the right metal roofing material and style depends on factors like climate, budget, architectural style, and desired longevity. Steel is the most common and cost-effective, aluminum suits coastal areas, copper and zinc offer premium durability and aesthetics, and standing seam panels provide the best weather resistance and modern look.
Consulting with a reputable local roofing contractor can help evaluate all the options and find the metal roof that best fits a home's needs and personal preferences.
