In hot, humid climates, fiber cement and quality vinyl are the most common recommendations.
- Fiber cement: resists rot, moisture and termites.
- Vinyl: won't rot; choose heavier gauge for storms.
- Engineered wood: treated against rot but needs sealed edges.
- Avoid untreated wood without diligent maintenance.
