7. Best Practices for Selection & Installation
• Use manufacturer‐recommended screws with rubber washers for waterproofing
• Panels require proper roof slope (≥3° for square‑wave, ≥5° for round‑wave)
• Ensure adequate ventilation under the roof to reduce heat buildup
• Inspect and clean shavings yearly to prevent rust
