Using Metal Siding Panels: Costs & Dangers

When constructing a massive pole barn, a detached garage, or a heavily modern custom home, architects and builders frequently abandon traditional vinyl siding or brick, opting instead for the rugged, industrial durability of metal. Installing vertical metal siding panels creates a striking, hyper-modern aesthetic while providing an impenetrable, 50-year shield against severe weather. However, many DIY homeowners attempt to cut massive corners by simply screwing cheap metal roofing on walls. Before you wrap your building in steel, you must understand the exact metal siding prices and the massive engineering differences between a roof panel and a wall panel.

Before you start pricing out massive 20-foot sheets of steel siding, you must know your exact square footage. While our primary tool is for roofs, the math is identical for walls.

Can You Use Metal Roofing as Siding?

The most common question from DIY builders is whether they can simply order extra metal roofing dimensions and screw them vertically onto the walls of their building.

• The Short Answer: Technically, yes. A high-quality standing seam or corrugated metal roof panel is fiercely waterproof and will effortlessly repel rain when installed vertically as wall cladding.
• The Massive Danger: The primary danger is not waterproofing; it is impact resistance. A roof is heavily protected from blunt force impacts. A wall is constantly battered by lawnmowers throwing rocks, vehicles backing up, kids kicking soccer balls, and massive hail driving sideways.
• If you use an incredibly thin, cheap 29-gauge metal roofing panel on a ground-level wall, a single stray rock from a lawnmower will permanently dent and deform the panel, ruining the aesthetic of your home instantly. If you use metal on walls, you must aggressively upgrade to a much thicker, heavier gauge of steel (like 24-gauge or 22-gauge) to prevent massive cosmetic damage.

The Different Types of Metal Siding Panels

When you decide to wrap a building in metal, you have three primary profiles to choose from, each offering a vastly different aesthetic and price point.

1. Corrugated Siding (Wavy Tin): The cheapest and most common option for massive agricultural pole barns. The classic wavy “S” pattern provides excellent structural rigidity, allowing it to span across open framing. It is installed with thousands of exposed screws.
2. Board and Batten Steel: Highly popular for the modern farmhouse aesthetic. It perfectly mimics the look of traditional wooden board and batten siding, featuring wide, flat panels separated by a raised vertical rib.
3. Flush Wall Panels (Architectural): The pinnacle of modern luxury homes. These panels sit completely flat against the wall with zero exposed screws (hidden fastener system), creating an incredibly sleek, seamless, hyper-modern industrial aesthetic.

The Current Metal Siding Prices (Material Only)

Because metal siding is manufactured in massive, custom-cut lengths (often 12 feet to 20 feet long), it is sold by the square foot or linear foot.

• Cheap Corrugated Siding: For basic 29-gauge agricultural panels, the raw material cost is incredibly affordable, typically ranging from $2.00 to $3.50 per square foot.
• Premium Steel Siding Panels for Homes: If you upgrade to thick 24-gauge steel with a premium Kynar 500 paint finish (to prevent massive fading), the raw material cost jumps significantly to $5.00 to $9.00 per square foot.
• Aluminum Metal Siding Panels: If you live on the coast, you must abandon steel and buy pure aluminum to prevent massive saltwater rusting. Premium aluminum siding panels easily cost $8.00 to $12.00 per square foot for the raw materials alone.

Pole Barn Steel Siding Prices vs. Residential Siding

When a homeowner sees a massive 60-foot pole barn completely wrapped in metal for $10,000, they wrongly assume they can side their residential home for the exact same price.

• The Pole Barn Advantage: A pole barn is a massive, simple square box. The builder can order 60 identical 16-foot panels and rapidly screw them to the massive wooden posts. The labor is incredibly fast and cheap.
• The Residential Nightmare: A residential home has dozens of windows, multiple doors, complex corners, electrical meters, and air conditioning units. The siding crew must manually cut, trim, and perfectly flash the metal around every single penetration to prevent massive water leaks inside the drywall. This extreme, slow custom fabrication drives the residential labor cost staggeringly high, easily pushing the total installed cost to $15,000 to $25,000+.

Conclusion: The 50-Year Armor

Installing vertical metal siding panels is an incredible architectural choice that provides an utterly unique, modern aesthetic and a permanent, fireproof, 50-year shield against the elements. However, you must avoid the massive trap of using cheap, thin roofing panels that will instantly dent at ground level. By investing in heavy, 24-gauge premium steel siding sheets, you guarantee your building will look flawless and remain completely maintenance-free for decades.

Before you order massive, custom-cut lengths of heavy steel from a local roll-former, you absolutely must verify your total square footage. Head over to our Free Roofing Calculator right now. By inputting your building’s basic dimensions, the tool will instantly output your exact total square footage, giving you the flawless data required to order the perfect amount of material.

Frequently Asked Questions

Does metal siding interfere with WiFi or cell service?

If you wrap your entire house in solid steel siding and install a steel roof, you are essentially building a massive Faraday cage. This will significantly degrade incoming cell phone signals and radio waves. If you live in an area with already weak cell service, you will likely need to install a simple, inexpensive cell signal booster inside the home.

Does metal siding rust?

If you buy cheap, unpainted galvanized steel, yes, it will eventually rust. However, modern residential steel siding panels are heavily coated in Galvalume (a zinc-aluminum alloy) and then baked in a premium Kynar 500 paint finish. This multi-layered defense guarantees the steel will not rust or fade for 30 to 40 years.

Do I need to ground metal siding?

If the building is a massive agricultural barn or a commercial steel structure, local electrical codes often require the metal panels to be safely grounded to the earth to protect against lightning strikes. For standard residential homes installed over a wood frame with a moisture barrier, grounding the exterior siding is rarely required, but you must always consult your local building inspector.
