Types of Metal Roofing: A North Carolina Guide to Panels, Profiles & Uses

Picking a metal roof starts with one question: what are you building, and how should it look and perform 30 years from now? There are dozens of types of metal roofing on the market, but most North Carolina homes, barns, and shops come down to a few proven steel panel profiles.

This guide breaks down the main types of metal roofing, how they differ, and which ones fit homes, barndominiums, pole barns, workshops, and commercial buildings. It comes from the team at On Time Metal in Hiddenite, NC, where we supply metal roofing, siding, and trim to homeowners, farmers, contractors, and business owners across the region.

In this guide:

• The two main types of metal roofing systems
• The roofing and siding panels On Time Metal offers
• Other metal roofing materials you’ll hear about
• 26 vs. 29 gauge steel
• Which panel fits your project
• Colors, trim, and delivery
• Common questions

The Two Main Types of Metal Roofing Systems

Every metal roof panel falls into one of two groups, based on how it attaches to the building. Understand this and the rest of your decision gets much easier.

Exposed Fastener Panels

With an exposed fastener system, screws go straight through the face of the panel into the framing or roof deck. Each screw has a rubber washer that seals the hole. You can see the fasteners on the finished roof.

Why people choose them:

• Lower cost. Less material and simpler installation keep the price down.
• Faster install. Panels go up quickly, which saves labor on large roofs.
• Roof and wall use. The same panel often works for both roofing and siding.
• Post-frame friendly. They’re a natural fit for pole barns, garages, and ag buildings.

The trade-off: washers age over time, so exposed fastener roofs benefit from a periodic check of the screws.

Concealed (Hidden) Fastener Panels

With a concealed fastener system, each panel is secured along one edge with clips or a hidden fastening flange. The next panel snaps over it, covering the fasteners. No screws pierce the face of the roof.

Why people choose them:

• Clean, modern lines. No visible hardware, just crisp vertical seams.
• Fewer leak points. No exposed screws to back out or wear over the years.
• Premium curb appeal. A popular choice for custom homes and modern farmhouses.

The trade-off: concealed fastener panels cost more up front. For many homeowners, the long-term performance and appearance are worth it.

Metal Roofing & Siding Panels Available at On Time Metal

On Time Metal focuses on three panel profiles that cover almost every building in our area: two roofing panels and one dedicated siding panel. Each comes with a matching trim system, so your roof and walls finish clean from ridge to base.

Classic Rib Panel (Exposed Fastener)

The Classic Rib Panel is our proven, cost-effective workhorse. It uses an exposed fastener system and delivers a clean, traditional ribbed look on both roofs and walls.

It’s the go-to panel for post-frame and rural buildings because it installs quickly and holds up to daily use. It also works on homes when budget matters and the classic ribbed look fits the style.

Best for: pole barns, garages, sheds, workshops, hay storage, livestock buildings, rural homes, and residential roofing or siding.

Standard trims include: ridge cap, endwall, sidewall flashing, chimney flashing, drip edge, residential and large residential rake, small and large corners, overhang trim, overhead door trim, L-trim in multiple sizes, and J-channel.

Snap Lock Panel (Concealed Fastener)

The Snap Lock Panel is our premium metal roofing option. Its all-hidden fastener system removes the risk of exposed screws backing out or leaking over time.

It costs more than Classic Rib, but it pays off in performance and curb appeal. The standard panel has subtle striations, and a flat panel is available as an option for an even sleeker finish.

Best for: custom homes, modern farmhouses, barndominiums, contemporary residential builds, farm offices, and high-end roofing projects.

Standard trims include: ridge cap, sidewall, endwall, gambrel, drip edge, rake, transition, and W-valley, all designed for the Snap Lock system.

Board & Batten Panel (Concealed Fastener Siding)

Board & Batten isn’t a roofing panel, but it’s often part of the same conversation. Most people choosing a metal roof also choose the walls, and this vertical look has become a favorite for homes and barndominiums.

The Board & Batten Panel recreates traditional wood board-and-batten siding in steel. Wide vertical boards and raised battens give it depth, and a concealed fastener system keeps it clean. It comes as a flat panel or with striations.

Best for: houses, barndominiums, modern farmhouse designs, farm stores, accent walls, and wainscoting. Pair it with a Snap Lock roof for a fully finished residential look.

Standard trims include: B&B corner trim, B&B starter, J-channel, L-trim in multiple sizes, overhang trim, overhead door trim, rat guard, track cover, and Z-bar.

Quick Comparison

Other Types of Metal Roofing Materials You’ll Hear About

Panel profile is one choice. The metal itself is another. On Time Metal supplies panels made from high-grade steel with a protective coating against rust, fading, and weather. Steel is the most common metal roofing material in the country because it balances strength, lifespan, and cost.

You’ll still run into other materials while shopping. Here’s a quick guide so you know what you’re comparing:

A note on “tin roofs”: when people in North Carolina say tin roof, they almost always mean a painted steel roof. True tin roofing is rarely used today.

For most homes, farms, and shops in the Piedmont and foothills, coated steel panels deliver the best value. The specialty metals above are usually reserved for accents or high-end architectural work.

26 Gauge vs. 29 Gauge Steel

On Time Metal offers 26- and 29-gauge panels, custom-cut to your exact lengths. With steel, a lower gauge number means thicker metal.

• 29 gauge is lighter and more economical. It’s a common choice for sheds, garages, many homes, and general-purpose buildings.
• 26 gauge is thicker and stiffer. It resists dents better and is often chosen for heavy-use ag buildings, commercial projects, and roofs where extra strength matters.

Custom-cut lengths also mean fewer seams and less waste on the job. Tell us your building dimensions and we’ll help you pick the right gauge for your framing and budget.

Which Type of Metal Roofing Fits Your Project?

The right panel depends on what you’re building. Here’s how our customers usually match panels to projects.

Homes

For houses, the choice usually comes down to looks and budget. Snap Lock gives you a premium concealed fastener roof with clean lines. Classic Rib gives you a durable, traditional roof at a lower cost, especially on rural homes.

Pair either roof with Board & Batten or Classic Rib siding. See all options on our metal roofing and siding for homes page.

Barndominiums

Barndominiums blend living space with shop or storage space, so they need a roof that looks residential and works hard. A Snap Lock roof with Board & Batten walls is a popular modern farmhouse combination.

Pole Barns & Agricultural Buildings

Livestock barns, equipment sheds, hay storage, riding arenas, and farm workshops need panels that handle weather and daily wear. Classic Rib is the standard choice for this work because it’s durable, versatile, and cost-effective.

For farm offices, farm stores, or hybrid home-and-barn projects, Snap Lock and Board & Batten add a more finished look. See barn and ag building panels and agricultural pole building packages.

Sheds & Outdoor Structures

Storage sheds, utility buildings, and lean-tos need reliable protection with little upkeep. Classic Rib is a practical, affordable fit. See shed roofing and siding panels.

Garages & Workshops

Garages, hobby shops, and workshops protect tools, vehicles, and equipment. Classic Rib roofing and siding is the most common pick, and we also supply garage doors built for daily use. See garage and workshop panels and residential pole buildings.

Commercial Buildings

Warehouses, offices, storage facilities, retail spaces, and industrial buildings benefit from metal’s durability, low maintenance, and energy efficiency. Metal roofing can help lower overhead costs over the life of the building. See our commercial pole buildings.

Contractors & Wholesale Buyers

Builders running multiple jobs need consistent supply and fast turnaround. We offer contractor pricing, and our wholesale division works with carport manufacturers, portable storage builders, and building material suppliers. Existing customers can manage orders through the customer portal.

Why Metal Roofing Works in North Carolina

Western Piedmont and foothills weather is tough on a roof. Summers bring heat, humidity, and hard thunderstorms. Winters can bring ice, snow, and the occasional hailstorm. Metal handles all of it.

• Built to last. Quality metal roofing may be the last roof you ever buy, while asphalt roofs often need replacing several times over the life of a home.
• Weather resistant. Metal resists cracking, shrinking, and erosion, and stands up to snow loads, hail, and wind.
• Energy-conscious. Reflective finishes help cut cooling costs during long Carolina summers.
• Low maintenance. No rot, no warping, and no pest damage like wood can suffer.
• Less tear-off. Metal can often go over existing surfaces, which can save on removal costs. Check local code and your roof’s condition first.
• Eco-friendly. Metal often contains recycled content and keeps old roofing out of landfills.
