Patio cover vs pergola: which roof should you put over your patio?
A patio cover is a solid roof that stays as it is. A pergola roof can change: slats, fabric or louvers that close. Want shelter against the house and open sky when you like? A wall-mounted louvered pergola does both. Want a roof that never changes? Get patio cover quotes locally.
Sellers blur the words. Purple Leaf calls one kit both a pergola and a patio cover, so judge the roof, not the label.

The difference: a roof that stays shut or one you can change
A patio cover is a solid roof on a frame, often aluminum, sold to fix to a house or to stand free. A pergola roof is made of slats, fabric or louvers.
| Patio cover | Louvered pergola | Open-slat or canopy pergola | |
|---|---|---|---|
| The roof | Solid panels, sometimes insulated | Aluminum louvers that turn open and closed | Fixed slats, or a fabric canopy |
| Does the roof move? | No | Yes, by crank or motor | A sliding canopy can; slats do not |
| Fixed to the house? | Sellers sell it attached or free-standing | Wall-mounted kits exist; makers differ on whether to attach (below) | Bracket kits, with your own lumber and anchors |
The patio-cover column follows how Hansø and Four Seasons describe the product. Your building department may use the word differently, so ask what it calls the roof you are buying.
Rain, light and heat are where sellers disagree. Read what they say as marketing, not measurement.
What sellers say about rain, light and heat
Makers disagree on rain. Hansø says its closed louvers make a sealed, waterproof roof. Purple Leaf says a closed louvered roof handles normal rain well but is not a sealed room. If dry dinners in heavy rain matter, ask the maker what its warranty says about weather and about water at the roof edge.
On light, The Luxury Pergola says a solid roof can feel darker and more enclosed underneath, and Purple Leaf says its adjustable roof gives more daily comfort than a fixed patio cover. On heat, Hansø says open louvers vent hot air and a solid panel can trap it. The Luxury Pergola says insulated panels run up to 20 degrees cooler. Nobody gives a baseline, so ask for the panel construction before you trust the claim. All three sell louvered pergolas.
Louvered pergolas that fix to your house
These three kits mount to a wall, and all are louvered. The attached pergolas page lists every kit that can fix to a house, including the freestanding-or-wall-mounted ones.
A louvered roof on a frame built for the wall, and the one Purple Leaf titles both pergola and patio cover. Skip it if your wall is not brick, concrete or wood stud, or if you want wall fixings in the box.

Steel | Manual louvers | 10×10 – 20×10 ft
Wall-mounted
Steel, manual louvers, and the maker says it permanently attaches to your house. Skip it if you want motorized louvers.
EROMMY Wall-Mounted Louvered Pergola
Last observed price $2,999.99
Aluminum | Manual louvers | 10×13 – 12×20 ft
Wall-mounted
Out of stock
Manual louvers, built for the wall. Skip it if you expect weather damage to be covered: the warranty excludes it, and improper installation too.
Want shade, not rain cover? The Toja Grid wall-mount bracket kit is a bracket kit: you supply the lumber and the wall anchors. It is not a roof that sheds rain.
Check the warranty before you fix any roof to your house
Against a house, the question that matters is whether the maker allows it. Read the warranty for the words “attached”, “wall” or “building” before you read the spec sheet. A kit sold in a wall-mounted version is not proof that its warranty covers one.
Hansø is the clearest case. It sells a wall-mounted version of every pergola, yet its warranty says the pergolas “should not be attached to the buildings”. It also excludes water getting in between the wall and the pergola. Watch out: get Hansø’s answer in writing before you order a wall-mounted one.

As published by Hansø Home. Terms and exclusions are the manufacturer’s. We quote the wording; we do not score it.
NoteThe exclusions include: “Runoff or water infiltration between the wall and the Pergola in the case of an installation attached to a building. Our Pergolas are a free-standing construction and should not be attached to the buildings.” Hansø sells a wall-mounted version of each family at the same price as the free-standing one.

Other makers are plainer. Backyard Discovery says its Evanston “permanently attaches to your house” and tells you to check local codes and your HOA first. Purple Leaf says its Caesar is designed for brick, concrete or wood stud walls. Neither says what its warranty does about the wall.
Permits: ask whether attaching changes yours
Ask your building department whether attaching the roof to the house changes the permit, and what it calls the roof you are buying. Tell it the roof type: slats, canopy, louvers or solid panels.
Zen Pergolas, a bracket-kit seller, says an open pergola with spaced rafters or slats may be classified differently from a patio cover with a solid roof. That is a reason to ask, not a rule. Our pergola permit guide shows how attaching and the roof type change the answer, city by city. The permits and extras section of the statistics page shows how five places differ.

Questions
What is the difference between a patio cover and a pergola?
A patio cover is a solid roof that stays as it is. A pergola roof is slats, fabric or louvers, and louvers move. Sellers use both words loosely, so check what a listing means by it. Everything about rain, light and heat on this page is a seller’s claim.
Is a louvered pergola a patio cover?
No, though some sellers call it one. Purple Leaf titles its Caesar Wall Mounted both “Louvered Pergola” and “All-Aluminum Patio Cover”. Judge the roof, not the label: louvers that open make it a pergola roof.
Can a pergola be attached to the house?
Yes, if the maker allows it, and makers differ on what their warranties allow. Hansø sells a wall-mounted pergola but its warranty says the pergolas “should not be attached to the buildings”. Backyard Discovery says its Evanston “permanently attaches to your house”. Read the warranty and ask in writing.
Do I need a permit for a patio cover or a pergola?
Ask your building department first, and ask whether attaching to the house changes the answer. Our pergola permit guide checks your size, roof and attachment against the rules of 24 US places.
Is a patio cover cheaper than a pergola?
Hansø says a patio cover costs less up front, but it gives no source. Get itemised quotes for the same footprint, and compare what each includes before you compare the totals.
