Cedar pergolas in Castle Rock ($35-60/sq ft) read warm and traditional but require periodic re-staining. Aluminum ($45-75/sq ft) is low-maintenance and modern. Steel ($40-70/sq ft) is durable and customizable. All last 30+ years with proper care.
Cedar: Warmth and Tradition
Cedar offers warm, traditional pergola aesthetic. Western red cedar is the standard for Colorado climate. Naturally rot-resistant. Develops silver-gray patina over time if untreated, or maintains warm reddish-brown color with periodic staining. Maintenance: re-stain every 3-5 years or accept the silver-gray weathering. Lifespan with maintenance: 30-40 years. Cost: $35-60 per sq ft of cover installed in Castle Rock. Best for: traditional homes, mountain-style architecture, clients who want natural wood feel.
Aluminum: Low-Maintenance Modern
Aluminum offers modern, low-maintenance pergola aesthetic. Powder-coated aluminum components in any color. No staining, sealing, or rust concerns. Doesn't warp, rot, or attract insects. Maintenance: occasional cleaning with soap and water. Lifespan: 40-50 years. Cost: $45-75 per sq ft of cover installed in Castle Rock. Best for: contemporary homes, modern aesthetic, clients prioritizing low-maintenance, and high-altitude applications where wood can dry out.
Steel: Durable and Customizable
Steel offers durable, customizable pergola aesthetic. Often combined with wood (steel posts and beams with cedar rafters). Powder-coated for color and corrosion protection. Heavier than aluminum, more substantial appearance. Maintenance: similar to aluminum. Lifespan: 40-50+ years. Cost: $40-70 per sq ft of cover installed in Castle Rock. Best for: industrial-modern homes, clients wanting custom design, or larger-span pergolas where steel structural strength matters.
