1. Introduction
In the past 48 hours, architects and builders across North America have seen a surge in demand for sustainable, fire-resistant home exteriors—especially metal clad systems. According to a new industry report by BuildTech Weekly, searches for ‘corten steel siding cost’ and ‘zinc clad roof’ have jumped over 60% since last month, driven by wildfire concerns and modern design trends. If you’re considering a metal clad house or upgrading your current exterior, this guide will show you exactly how to install and maintain metal clad siding properly.
Metal clad isn’t just industrial—it’s stylish, durable, and increasingly popular for residential use. Whether you’re drawn to the rustic patina of corten steel siding, the sleek look of a standing seam facade, or the affordability of exterior corrugated metal siding, getting the installation and upkeep right is key.
2. Choosing the Right Metal Clad Type
Not all clad metals are created equal. Your climate, budget, and aesthetic goals should drive your choice.
- Corten steel siding: Ideal for dramatic, weathered looks; forms a protective rust layer but costs more upfront.
- Zinc metal siding: Self-healing, long-lasting (up to 100 years), and perfect for a zinc clad dormer or full facade.
- Aluminum clad steel: Lightweight, corrosion-resistant, and great for coastal areas.
- Copper siding: Premium option with natural aging; often used as accents.
- Colorbond standing seam or PAC CLAD HWP: Pre-finished, low-maintenance options widely used in metal clad buildings.
Also consider clad metal meaning: it refers to a composite material—like stainless clad aluminum or titanium clad—where a thin layer of premium metal coats a stronger, cheaper base (e.g., mild steel plate). This gives you performance without the full price tag.
3. Step-by-Step Installation Guide
Installing metal clad siding correctly prevents leaks, warping, and premature wear.
3.1 Prepare the Wall Surface
Ensure your wall is structurally sound, dry, and covered with a proper moisture barrier. Use furring strips if needed to create an air gap—this improves ventilation behind vertical standing seam metal siding and reduces condensation.
3.2 Measure and Cut Panels
Use metal sheet cutting tools (like aviation snips or a circular saw with a metal-cutting blade) to size your panels. For aluminum clad sheet or stainless steel metal plate, always wear safety gear—edges can be sharp.
3.3 Install Starter Strip and First Panel
Begin at the bottom corner. Secure the starter strip level, then attach the first panel using corrosion-resistant fasteners compatible with your metal type (e.g., stainless for copper or zinc).
3.4 Overlap and Fasten Subsequent Panels
Follow manufacturer specs for overlap—typically 1–2 inches for corrugated steel facade or interlocking seams for PAC CLAD standing seam roof systems. Never over-tighten screws; allow for thermal expansion.
3.5 Add Trim and Flashing
Use PAC CLAD coping and column covers around windows, doors, and corners. Proper flashing prevents water intrusion—critical for any metal clad wall system.
4. Common Problems and How to Fix Them
Even the best metal clad siding can face issues if not maintained.
- Rust spots on corten steel before patina forms: Clean with a wire brush and let weather naturally. Avoid sealants—they trap moisture.
- Oil-canning (waviness) in large panels: Caused by improper fastening. Re-secure with hidden clips or add intermediate supports.
- Scratches on aluminum clad stainless steel: Touch up with matching paint or leave—it won’t compromise integrity.
- Condensation behind siding: Improve airflow with vented rainscreen details or metal clad insulation rated for exterior use.
5. Maintenance Tips for Longevity
Metal clad requires far less upkeep than wood or vinyl—but not zero.
Rinse your metal facade annually with water to remove salt, pollen, or pollutants. For stubborn grime, use mild soap and a soft brush—never abrasive pads.
Inspect fasteners and seals every 2–3 years. Replace any corroded screws, especially on aluminum clad steel wire connections or metal clad electrical wire entries.
If you have a steel clad house near industrial zones, check for acid rain damage—zinc and copper are more vulnerable than stainless or aluminum.
6. Cost Considerations
Corten siding cost ranges from $7–$15/sq.ft., while zinc clad roof systems can hit $20+/sq.ft. Aluminum clad sheet is more affordable ($4–$8/sq.ft.) and widely available as ‘aluminum sheet for sale’ online or locally.
Don’t forget hidden expenses: furring strips, specialized fasteners, and professional cutting for thick steel plate (like 1/4 steel plate or 3/16 metal plate) can add 15–20% to your budget.
7. Conclusion
Metal clad siding blends durability, sustainability, and modern style—making it a smart choice for today’s homes. By selecting the right clad metals, following precise installation steps, and performing light maintenance, your metal clad house can look stunning for decades. Whether you opt for a bold corten steel facade or a subtle zinc metal siding, this guide ensures you’ll avoid common pitfalls and maximize your investment.
