Slat & Shade

Pergolas

A pergola is the only shade structure that can be a permanent part of your house or a weekend kit, and the gap between the two in published durability specs is enormous. This is where we sort them out.

We compare published manufacturer specifications, warranty terms and owner-reported failure modes. We have not physically tested these structures. How we judge shade structures

Aluminum louvered pergola with open roof slats over a paved backyard patio in daylight

The short answer

Buy an aluminum louvered pergola if you want adjustable shade and rain cover with a published wind rating. Buy a cedar kit if you want a pergola that looks like architecture and can be repaired board by board. Either way, the wind rating only holds if you anchor it to concrete.

What a pergola is actually good at

A pergola is a post-and-beam frame with an open or louvered roof. That single fact explains almost everything about how it behaves: wind passes through an open roof instead of pushing against it, which is why pergolas survive weather that flattens pop-up canopies, and it is also why a fixed-slat pergola will not keep you dry.

The category splits cleanly in two. Louvered aluminum pergolas have pivoting slats you close for rain and open for airflow, plus integrated gutters in the beams. Fixed pergolas — cedar, vinyl or plain aluminum — have a permanent slat or lattice roof and give you dappled shade, not shelter. A third group, the solid-roof "pergola" with a polycarbonate or steel panel, is really a patio cover wearing a pergola's name; it sheds rain fully and catches far more wind.

If you are here because you want shade over a dining table you will actually use in August, a fixed slatted roof will probably disappoint you — see do pergolas provide shade for the numbers on how much sun a slatted roof really blocks and at what time of day.

The three specs that decide whether yours lasts

Almost every pergola listing leads with size, color and "heavy duty aluminum". None of those tell you anything. Three figures do, and only some manufacturers publish them.

  • Wind rating, and the condition attached to it. The best-documented pergolas state both — PURPLE LEAF publishes 72 mph for the Athena but only when it is secured with expansion screws into a hardened floor, and Backyard Discovery publishes 100 mph for the Beaumont "when properly anchored". A rating with no anchoring condition attached is a marketing number. How we read wind ratings explains why.
  • Frame wall thickness, not just the material. "Aluminum" covers a 1.5 mm powder-coated extrusion and a tinfoil-gauge tube equally well. Post dimensions and wall thickness are what resist twisting; a 4.33 in. crossbeam at 1.5 mm is a different structure from a 3 in. post at an unpublished gauge.
  • What the warranty actually covers, and for how long. One year on everything is the category norm. Five years on the roof and frame — as Domi publishes — is the outlier. Cedar kits often split the term: Backyard Discovery covers five years, Yardistry covers one year on materials but five on the lumber against rot. Those are different promises. Materials and warranties compares the fine print.

Aluminum or wood — the honest version

Aluminum wins on maintenance and loses on repairability. A powder-coated aluminum frame needs washing and nothing else for a decade, but when the coating chalks on the sunward face there is no sanding it back — you live with it or you replace the member. Cedar needs re-sealing every two to three years and will check and gray if you skip it, and a checked cedar beam can be replaced with one board from a lumberyard.

For the buy-it-for-life shopper that trade is closer than it looks, and it comes down to whether you will actually do the maintenance. If you will, cedar with 6x6 posts outlives most budget aluminum. If you won't, aluminum degrades more gracefully than neglected wood. The full comparison is in aluminum vs wood pergolas.

What is not close: snow. A fixed or louvered aluminum roof has a published load figure sometimes; a cedar trellis roof has an open structure snow falls straight through. If you are in snow country, the roof type matters more than the frame material — start with snow load explained.

Before you buy: the three things that stop the project

  • Anchoring surface. A pergola anchored into 4 in. of concrete behaves nothing like the same pergola on pavers or grass. If you don't have a slab, read how to anchor a pergola before you choose a model — some kits cannot legitimately be installed without one.
  • Permits. Freestanding pergolas under a certain footprint are often exempt; attaching one to the house frequently is not, because it becomes a structural alteration. Pergola permits and HOA rules covers what to check and who to ask.
  • Size. The most common regret is a pergola that covers the table but not the chairs when they are pushed back. Pergola sizes works from furniture outward instead of from catalog sizes inward.

Head-to-head comparisons

Every one of these answers the same question from a different starting point — and every one is willing to tell you to buy the other thing.

Questions people ask

Are pergolas wind resistant?
An open-roof pergola handles wind better than any fabric structure, because air passes through the slats instead of loading them. Published ratings among the models we track run from 70 mph to 100 mph — but every one of those figures assumes the pergola is bolted to a hard surface. Unanchored, the rating means nothing. See wind ratings explained.
What is the most durable pergola material?
Powder-coated aluminum has the longest maintenance-free service life; cedar has the longest repairable life. Neither is universally "most durable" — the deciding factor is whether the structure gets maintained. Aluminum vs wood sets out the failure modes for each.
Do I need a permit for an attached pergola?
Often yes, and more often than for a freestanding one, because bolting a structure to the house is a structural alteration in many jurisdictions. Requirements vary by jurisdiction — check locally before you buy. Pergola permits and HOA explains what the question usually hinges on.
How long does a pergola last?
Manufacturer warranties run one to five years, which is not the same as service life. Our lifespan guide collects what owners report per material, and what fails first in each case.
Is a louvered pergola worth the extra cost over a fixed roof?
If you want to use the space in rain, yes — a closed louvered roof with integrated beam drainage is the only pergola configuration that keeps a table dry. If you only want sun relief, a fixed slatted roof does that for much less. Louvered vs fixed roof pergolas has the decision table.
