Louvered vs Fixed Roof Pergola.

Flexibility

Louvered pergolas adjust to the weather — open blades for sun, partial for filtered shade, closed for rain protection. Fixed roofs are one setting only. For UK weather, the flexibility of louvers is often the deciding factor.

Cost difference

A louvered aluminium pergola typically costs £2,000–£5,000 more than the equivalent fixed-roof aluminium build. Adding motorisation increases the gap by another £1,000–£3,000.

Maintenance and longevity

Fixed roofs have fewer moving parts and lower long-term maintenance. Louvered roofs are well-engineered but include motors, bearings and seals that can need attention after 10–15 years. Both types comfortably last 20+ years if well made.

When fixed makes sense

Fixed-roof pergolas are a good choice if budget is tight, the pergola is mainly for summer shade, or if you prefer the simplicity. Polycarbonate and glass roofs are both fully waterproof and significantly cheaper than louvered alternatives.
