1. Introduction
Just 24 hours ago, a major architecture firm unveiled a new residential project in Portland featuring a striking corten steel facade that’s already gone viral on design platforms. The surge in popularity of metal clad houses isn’t just about aesthetics—it’s driven by durability, low maintenance, and sustainability. Whether you’re building from scratch or re-cladding an existing structure, understanding how to properly install and care for your metal exterior is key.
In this guide, we’ll walk you through the entire process—from selecting the right type of metal cladding to installation tips and long-term upkeep. We’ll also address common pitfalls and how to avoid them, so your metal clad house stays beautiful and functional for decades.
2. Choosing the Right Metal Clad Material
Not all metal cladding is created equal. Your choice depends on climate, budget, and design goals. Here are popular options:
- Corten steel siding: Rustic, self-protecting patina; ideal for modern or industrial looks. Note: corten siding cost ranges higher but offers longevity.
- Zinc facade or zinc clad roof: Naturally corrosion-resistant with a sleek gray finish that ages gracefully.
- Copper siding: Develops a green patina over time; premium price but unmatched elegance.
- Colorbond standing seam or vertical standing seam metal siding: Pre-painted, low-maintenance, and available in dozens of colors.
- Exterior corrugated metal siding: Budget-friendly and rugged, often used for sheds or rustic homes.
Also consider clad metals like aluminum clad steel or stainless clad aluminum for enhanced performance. For roofing, pac clad standing seam systems (including pac clad coping and column covers) offer commercial-grade reliability.
3. Preparing the Structure
Before attaching any metal cladding, ensure your wall or roof substrate is structurally sound, level, and properly insulated. Use metal clad insulation or aluminum clad pipe insulation where needed to prevent thermal bridging.
Install a weather-resistant barrier (WRB) over sheathing to protect against moisture. This is especially critical for metal clad walls exposed to heavy rain or snow. Don’t skip this step—even the best metal facade won’t compensate for poor underlying preparation.
4. Installing Metal Clad Siding or Roofing
Follow these general steps for most metal cladding systems:
- Start at the bottom (for walls) or eave (for roofs).
- Use corrosion-resistant fasteners rated for your specific metal type (e.g., stainless steel for coastal areas).
- Maintain proper expansion gaps—metal expands and contracts with temperature changes.
- For standing seam systems like pac clad hwp or colorbond standing seam, use concealed clips to allow movement and prevent leaks.
- When working with corrugated steel facade panels, overlap seams correctly and seal joints with compatible sealant.
If you’re using aluminum clad sheet or aluminium clad steel, handle edges carefully—they can be sharp. Always wear cut-resistant gloves during installation.
5. Common Problems and Fixes
Even the best-installed metal clad house can face issues. Here’s how to troubleshoot:
- Rust spots on steel plate surfaces: Clean with a wire brush, apply rust converter, then repaint with metal-compatible paint.
- Dents from hail or debris: Small dents can often be left alone (especially on corten), but large ones may require panel replacement.
- Condensation behind cladding: Improve ventilation or add vapor barriers during re-installation.
- Fading or chalking on painted systems: Repaint with high-quality acrylic or PVDF-coated finishes designed for metal.
Avoid using abrasive cleaners on zinc metal siding or copper—it can damage the protective patina.
6. Maintenance Tips for Longevity
Metal clad buildings are low-maintenance, but not zero-maintenance. Schedule these tasks annually:
- Rinse off dirt, pollen, or salt buildup with a garden hose (no pressure washer—it can force water behind panels).
- Inspect fasteners for looseness or corrosion.
- Check seals around windows, doors, and penetrations.
- Trim nearby vegetation to prevent scratches and moisture retention.
For specialty finishes like titanium clad or electroplating-enhanced surfaces (e.g., chromium plate or nickel sulfamate coatings), follow manufacturer guidelines closely.
7. Cost Considerations
While initial costs vary—corten steel siding cost is higher than standard corrugated steel—the long-term savings on painting, repairs, and energy efficiency often justify the investment. Compare quotes for materials like 316 stainless steel plate vs. mild steel plate based on your environment.
Don’t forget hidden expenses: delivery of thick steel plate, metal sheet cutting services, or custom elements like pac clad column covers can add up.
8. Conclusion
A metal clad house combines modern style with exceptional resilience. By choosing the right materials—whether it’s a zinc clad dormer, steel clad inc panels, or aluminum diamond tread plate accents—and following proper installation and care practices, you’ll enjoy a stunning, durable exterior for years to come. As seen in today’s trending architectural projects, metal cladding isn’t just a trend—it’s the future of smart, sustainable building.
