Pergolas in South Florida
A pergola is a device for reclaiming hours. Decide which hours you want back and the structure, its position and its orientation follow from that.
Most pergolas shade the wrong thing
Not because they were badly built. Because they were positioned on a plan rather than on the property, and a plan does not know where the sun is at four in the afternoon in June.
A pergola put where it looks balanced on a drawing will cast its shade wherever the geometry sends it. Frequently that is across a stretch of lawn, or onto a fence, at exactly the hour you wanted to be sitting under it. The structure is fine. It is simply not doing the job it was bought for.
So the first question is not what the pergola should look like, or even what it should be made of. It is: which hours do you currently avoid this space, and where are you standing when you avoid it? Everything below follows from the answer.
Design considerations
Sun path, orientation and the hours you get back
Which way the space faces
A west-facing patio is punished late in the day, when low sun comes in almost horizontally and a roof directly overhead does very little about it. An east-facing space has the same problem in reverse, in the morning. A space that opens south takes high sun through the middle of the day, which overhead cover handles well.
These three situations want different answers. Low-angle sun is dealt with by depth, by a vertical element, or by a drape at the side — not by adding slats above. Overhead sun is dealt with above. Confusing the two is the most common reason a finished pergola disappoints.
The hour matters as much as the direction
Shade moves. A structure that covers the dining table at noon may have moved off it by the time anyone sits down to eat. Working out where the shadow actually falls at the hours the space gets used is a site exercise, done standing in the yard, and it routinely shifts the proposed position by several feet.
What is already shading you
Mature trees, the house itself and a neighbouring building are all doing part of the job for free at certain hours. A pergola positioned without accounting for them can end up duplicating shade that already exists while leaving the hot part of the space untouched.
Three questions that fix the position
When do you avoid this space? A time of day, not a season.
Where do you want to be sitting? A specific spot, not the general area.
What does the sun do at that hour, from that spot? Checked on site rather than assumed from a plan.
Answer those three and the position, the footprint and the roof type are largely decided for you.
Options
Attached or freestanding
The first structural fork, and it is decided by where the shade has to land rather than by preference.
| Attached to the house | Freestanding | |
|---|---|---|
| Best when | The space to cover is directly against the house and the sun crosses it. Extends the indoor room outward. | The shade needs to be out in the yard — over a lounge area, a dining spot, part of a pool surround. |
| Structure | One side carried by the building, so fewer posts and a lighter footprint on the paving. | Posts on every corner, which means more footings but complete freedom of orientation. |
| What it demands | A sound fixing into the structure and careful detailing where roof meets wall, so water is directed away from the building. | Footings that carry the whole structure, and a position that reads deliberately rather than randomly placed. |
| Watch for | Threshold heights, door and window head heights, and existing drainage at the wall. | Looking marooned. A freestanding structure needs a reason to be where it is — a table, a view, an edge it relates to. |
Options
Roof types and material families
Concepts rather than a catalogue. The specific system and material for your project are settled at consultation against the site, the look you want and the budget.
Open frame
Posts and beams with little or nothing above. Defines an outdoor room and carries planting or a retractable fabric, but gives structure rather than real shade. Best where the enclosure matters more than the cover.
Fixed slats
Genuine shade for part of the day. How much depends on slat spacing, slat depth and — critically — which way they run relative to the sun. The same slats rotated ninety degrees give a noticeably different result.
Adjustable louvres
Louvres that rotate, so cover can change through the day and open up in the evening. The most flexible answer to a space used at several different hours, and the one with moving parts to maintain.
Fabric and drapes
Side drapes address the low-angle sun that overhead cover cannot, and add privacy. Retractable canopies give cover on demand. Both are seasonal items in a storm climate — worth planning where they go when they come down.
On materials
Timber, powder-coated aluminium and composite systems all appear in South Florida yards, and they trade differently on appearance, weight, maintenance and how they behave near the coast. Rather than list specifications we cannot tie to your project, the material is chosen at consultation against the site, the elevation it sits against and how much upkeep you want to take on. What we will not do is tell you a material is maintenance-free.
Design considerations
Scale and proportion
The difference between a pergola that looks built-in and one that looks bought.
- Height against the house. A structure whose beam line sits just under the eaves reads as part of the building. One noticeably lower reads as an addition, and one that crowds a window or door head reads as a mistake. On an attached pergola this is usually fixed by the elevation, which is a constraint worth knowing before design begins.
- Footprint against the paving. A pergola covering a small fraction of a large patio looks stranded; one that oversails the paved area entirely looks like the paving ran out. It generally wants to relate to an edge or a zone rather than float in the middle.
- Post spacing against the furniture. Posts land where they land, and a post in the middle of where a chair goes is a daily irritation. Setting out the furniture positions first, then the posts, avoids it.
- Depth for low sun. Where the space faces west or east, depth in the direction the sun comes from does more than area. A deeper, narrower structure can outperform a larger square one at the hour that matters.
- Sightlines from indoors. A pergola is seen through the glass for most of its life. It frames the view or it interrupts it, and which one is decided by where the posts fall relative to where you sit inside.
Integration
Where it meets everything else
Footings go in before paving
Posts need support below the surface in properly prepared ground. Formed while the ground is open, that costs very little. Retrofitted, it means lifting sections of finished paving and relaying them. If a pergola is even a possibility, say so before the patio is laid.
Over an outdoor kitchen
Cover transforms how often an outdoor kitchen gets used. It also changes how heat and smoke leave the cooking zone, so what goes above a grill is a design decision rather than a default.
Beside the pool
On a pool deck, a pergola is often what makes the loungers usable in the afternoon. Position it against where the sun actually is, allow for splash around the posts, and keep footings clear of the coping line.
Against the boundary
A structure near a fence line reads against it. Height and position of the two are worth deciding together, because a pergola backing onto the wrong boundary treatment loses most of its effect.
Being straight with you
Weather, structure and what we will not claim
We will not quote a wind rating on a web page
Structural performance figures belong to a specific product or a specific engineered design, for a particular configuration of members, fixings and footings. A number published on a marketing page tells you nothing about the structure that would actually be built on your property. You will get the figures that apply to what is being proposed for your site, from the manufacturer of the system or from the engineering for a custom design. Treat any contractor who offers a general rating before knowing your design with the caution it deserves.
What the climate does regardless
Sun. Sustained UV works on finishes continuously. Timber coatings, fabric and colour on any material are all affected, which is a maintenance consideration rather than a defect.
Rain. Water has to leave the structure and go somewhere sensible. On an attached pergola the junction with the wall is the detail that matters most; on any pergola over paving, the fall of the surface below still has to work.
Salt air. Closer to the coast, fixings and fasteners face a harsher environment than a few miles inland. It changes what is sensible to specify.
Storm season. Fabric, drapes and retractable canopies are seasonal items. Planning where they go when they come down is more useful than assuming it will be sorted out at the time.
Permitting. Requirements can vary by jurisdiction and project scope. Arco can discuss planning considerations for your specific project. It is worth raising early, since it can affect the design rather than just the paperwork — and an HOA may have separate requirements of its own.

Common questions
Pergola questions we are asked most
Attached to the house, or freestanding?
It depends on where the shade has to land. Attached is the answer when the space you want covered is right against the house and the sun arrives across it, and it uses the wall for one side instead of posts. Freestanding is the answer when the shade needs to be out in the yard, over a lounge area, a dining spot or part of a pool surround, and it gives you full freedom over orientation. The elevation, the threshold heights and where the sun actually sits at the hours you care about decide it, which is why it is settled on site.
How much shade does a pergola actually give?
Less than a roof and more than nothing, and how much depends on the roof type and its orientation. An open frame gives structure and a dappled effect rather than real cover. Fixed slats give genuine shade for part of the day, and how much depends on their spacing, their depth and which way they run relative to the sun. Adjustable louvre systems let you change it through the day. Anyone quoting a single shade percentage is describing a product, not your yard.
What wind loading is the structure built for?
That is specific to the product and the design, and it is not something we will quote from a website. Structural performance figures come from the manufacturer of the system being installed or from the engineering for a custom design, for the particular configuration, fixings and footings involved. We will give you the figures that apply to what is actually being proposed for your property. Treat any contractor who offers a general rating before knowing the design with caution.
Can a pergola go over a patio that already exists?
Usually, but the footings are the question rather than the structure. Posts need support that goes below the paving into properly prepared ground, so it generally means lifting sections of the surface, forming the footings, then relaying. That is a normal job when planned for. It is also why, if a pergola is even a possibility, it is worth saying so before a new patio is laid, when allowing for the footings costs very little.
What maintenance does a pergola need?
It follows the material. Timber wants periodic cleaning and recoating, and the interval depends on the finish and how much direct sun and rain it takes. Powder-coated aluminium mostly wants washing, with attention to fixings closer to the coast where salt air is a factor. Any adjustable mechanism has moving parts that want checking. Whatever the material, clearing debris off and out of the roof structure matters more here than in a drier climate.
Do I need a permit for a pergola?
Requirements can vary by jurisdiction and project scope. Arco can discuss planning considerations for your specific project during the on-site consultation. It is worth raising early, because it can affect the design rather than just the paperwork, and because an HOA may have its own separate requirements about height, position and appearance.
