Key Types Of Metal Roof Panels Explained
Standing Seam Metal Roof Panels
Standing seam panels are regarded as the gold standard for modern metal roofing. These panels feature raised vertical seams—or “legs”—which interlock to conceal fasteners. This design protects fasteners from weather, greatly extending the roof’s life.
Standing seam panels are custom-fabricated in long runs, reducing leak-prone horizontal seams. They’re available in both snap-lock and mechanically seamed versions. The snap-lock method is popular for homes due to straightforward installation, while mechanically seamed profiles provide the ultimate in wind and water resistance—ideal for harsh climates.
- Material Options: Steel (galvalume or galvanized), aluminum, copper, zinc
- Panel Widths: Typically 12–18 inches
- Applications: Premium residences, contemporary commercial, low-slope buildings
Exposed Fastener Metal Roof Panels
Exposed fastener panels are the most economical and easy-to-install metal roofing option. Panels are attached directly through their surface using color-matched screws with rubber washers, which are visible after installation. Although exposed to elements, proper fastener and washer installation prevents water infiltration.
These panels are favored for projects where cost and installation speed take priority. They’re offered in a variety of ribbed and flat profiles, providing flexibility for barns, workshops, and even residential homes seeking an industrial or farmhouse aesthetic.

- Applications: Garages, agricultural buildings, metal siding, lower-cost homes
Corrugated Metal Roof Panels
Corrugated metal roofing features a wavy surface profile, lending a rustic, rugged look to buildings. The undulating shape adds strength and rigidity, allowing use of lighter gauge metals. Corrugated panels are typically fastened with screws along the ridges, which helps prevent leaks.
Historically popular for barns and utilitarian structures, corrugated metal has become a trendy choice for cabins, mountain retreats, and contemporary homes aiming for an industrial edge. It’s also commonly found in coastal regions thanks to its resistance to severe weather.
- Material Options: Galvanized steel, galvalume, aluminum, copper
- Panel Widths: 24–36 inches standard
- Applications: Agricultural, mid-century modern homes, outbuildings
Modular Or Interlocking Metal Roof Panels
Modular metal panels are precision-shaped to replicate traditional roofing materials like shingles, shakes, slate, or tiles. Individual or small panels interlock on all sides, forming a watertight surface with a classic appearance.
These sheets often feature advanced coatings and are lightweight, making them suitable for re-roofing projects over existing shingles. The appearance can match wood shakes, clay tiles, and even stone slate with less maintenance and weight.
- Material Options: Steel, aluminum, copper
- Profiles: Shake, shingle, slate, tile, diamond
- Applications: Residential homes, higher-end commercial, historical restoration
Choosing The Right Metal For Your Roof Panel
Selecting the best metal for your roof panel depends on performance, climate, and budget requirements. Different metals offer varying resistance to corrosion, weight, and aesthetics.
- Steel: Most common, often coated in galvalume (aluminum-zinc alloy) or galvanized (zinc). Durable, economical, and available pre-painted for added corrosion resistance.
- Aluminum: Lightweight and rustproof, making it ideal for coastal climates. Can be factory painted for aesthetic flexibility, but may dent more easily than steel.
- Copper: Exceptional longevity (up to 100 years), develops a green patina, and seldom needs painting. One of the priciest options yet highly valued for aesthetics.
- Zinc: Naturally self-healing and corrosion-resistant, with a soft matte finish. Excellent for unique custom designs; more expensive than steel or aluminum.
Consider local climate, environmental factors, and architectural style when selecting a panel material. Coastal areas generally demand aluminum or high-grade coated steel, while inland structures benefit from galvanized or galvalume steel.
