Louvered Aluminum vs Cedar Pergola (2026) — Which to Buy
Louvered aluminum gives adjustable, no-maintenance shade; cedar gives warmth and looks but needs sealing and offers fixed shade. Here's the honest trade-off by climate, maintenance, and budget.
Once you've decided on a pergola, there's one real fork: modern louvered aluminum, or classic cedar. It's a genuine trade-off, not a 'the new thing is just better' situation — cedar still wins on looks for a lot of people. Here's how we'd choose, having built plenty of both across California.

Our Picks
Adjustable vs Fixed Shade
This is the headline difference. Louvered aluminum lets you rotate the roof slats — open for morning light and breeze, closed for full afternoon shade or a passing rain. You dial in exactly the shade you want, whenever. Cedar gives you a fixed amount of dappled shade set by the beam spacing — beautiful, but it is what it is, all year. If sun control is the whole point, louvered wins; if you want a sun-dappled, plant-friendly frame, cedar is lovely.
Maintenance (The Real Cost Difference)
Aluminum: essentially none. Rinse it occasionally. No rot, no rust, no repaint, no re-seal — for 15+ years. Cedar: needs re-sealing or staining every 1-2 years to keep from greying and checking, especially in California sun. That's a recurring weekend and a recurring cost. Factor it in — a cedar pergola's true price includes a decade of sealer and labor (or our maintenance visits).
Looks + Feel
No contest on warmth: cedar looks and smells like real wood and ages into a natural yard feature (if you let it grey) or stays rich (if you seal it). Aluminum looks clean, modern, and architectural — great with contemporary homes and hardscape, a little less 'garden.' Powder-coat colors help, but if your aesthetic is craftsman/rustic, cedar is the move; if it's modern, louvered aluminum looks purpose-built.
Climate + Longevity in California
Near the coast, aluminum is the safer long-term bet — salt air is hard on everything, and there's no rust to worry about. In hot inland areas, aluminum's adjustable shade and no-maintenance nature shine, and it won't dry-check the way wood can. Cedar does fine anywhere in CA if you stay on the sealing schedule; neglect it near the coast and it weathers fast. For lowest lifetime hassle, aluminum; for looks-first, cedar with upkeep.

Louvered aluminum or cedar pergola — which is better?
Louvered aluminum for adjustable, no-maintenance shade and modern looks; cedar for warmth and classic looks if you'll re-seal it every 1-2 years. It's a looks-vs-upkeep trade-off.
How much maintenance does a cedar pergola need?
Re-sealing or staining every 1-2 years to prevent greying and checking, especially in California sun. Aluminum needs essentially none.
Is aluminum or wood better for the coast?
Aluminum — no rust, no rot, and salt air won't degrade it the way it weathers neglected wood.
Does a louvered pergola give better shade than cedar?
Yes, in the sense that you control it — open the slats for light and breeze, close them for full shade. Cedar gives a fixed amount of dappled shade.
Which lasts longer?
Aluminum with almost no upkeep for 15+ years. Cedar can match it but only if you stay on the sealing schedule.
