When Broken Arrow homeowners are choosing between aluminum and wood pergola systems, the upfront cost comparison is only half the picture. Maintenance, painting, and material replacement over a 10–15 year lifespan significantly affect the total investment. Here’s an honest lifetime cost breakdown.
Year 0: Installation Cost Comparison
For a 16×20 pergola with footings in Broken Arrow:
- Cedar pergola (custom built): $12,000–$22,000 depending on beam sizing, post size, and complexity
- Pressure-treated pine pergola: $9,000–$16,000 — less expensive material but requires paint/stain immediately and regularly
- Aluminum louvered system (powder-coated): $18,000–$35,000 depending on brand, size, and motorization
- Aluminum solid roof system: $15,000–$28,000 for a commercial-grade extruded aluminum system with integral drainage
Years 1–15: Maintenance Cost Comparison
Cedar Pergola
- Year 2–3: Restain or reseal — $400–$800 for a 16×20 pergola DIY; $800–$1,500 hired
- Year 5–6: Repeat staining — same cost
- Year 7–10: Board checking and splitting may require individual board replacement — $200–$600
- Year 8–10: Repeat staining — same cost
- Year 10–15: If posts weren’t properly treated and isolated from soil moisture, post base rot may require post replacement — $400–$1,200 per post
15-year maintenance estimate for cedar: $3,000–$7,000 in addition to initial installation cost
Pressure-Treated Pine Pergola
Higher maintenance than cedar due to more tendency to check and warp in Oklahoma’s heat cycles. Paint peeling is more common on pine than cedar. Similar maintenance cost range but potentially more frequent repainting needs.
Aluminum Louvered or Solid System
- Annual washing: 30 minutes with a garden hose — $0
- Powder coat touch-up if chipped: $20–$50 in touch-up paint, occasional
- Motor replacement (louvered systems): $200–$600 at year 10–15 if motor fails
15-year maintenance estimate for aluminum: $200–$800 in addition to initial installation cost
15-Year Total Cost Comparison (16×20 Pergola, Mid-Range)
- Cedar (custom built): $17,000 installed + $5,000 maintenance = $22,000 total
- Aluminum louvered system: $26,000 installed + $500 maintenance = $26,500 total
The gap is real but narrower than it first appears. The aluminum system also delivers better weather protection (solid or louver coverage vs. open slats) and requires genuinely zero maintenance time and attention — for homeowners who would rather not think about their pergola’s condition every 2–3 years, that has real value.
When Wood Makes More Sense
- Budget is the primary constraint
- You prefer the natural look and warmth of wood over metal
- You’re willing to maintain it on a regular schedule
- The design calls for climbing plants or a more organic, garden-integrated aesthetic
When Aluminum Makes More Sense
- You want a truly maintenance-free structure
- You want a louvered system for weather control
- You plan to be in the home for 15+ years and want a long-term investment
- The design calls for a contemporary, clean-lined aesthetic
