Buy right once: A pergola has to survive your worst storm, not an average day. Check its wind and snow ratings against your area, and size it for the furniture, grill or hot tub you may add later.
Before you buy, check:
- Wind and snow ratings vs your local design loads
- Footprint for future furniture, a dining table or a hot tub
- Permit, setback and HOA rules, and how it's anchored

Aluminum vs steel vs wood at a glance
| Aluminum | Steel | Wood (cedar, pressure-treated) | |
|---|---|---|---|
| Upkeep | Lowest; powder coat doesn't rot or rust | Low, but touch up chips in the coating to stop rust | Highest; stain or seal regularly |
| Strength for its weight | Lighter; ratings depend on profile thickness | Heavier and stiffer for the same size | Strong in large sections (6×6 posts); can check and warp |
| Coastal / humid | Good choice | Watch for corrosion at scratches and fasteners | Needs rot-resistant species and upkeep |
| Material cost (HomeGuide) | $10–$30 per sq ft (aluminum/metal)[1] | Included in "metal"[1] | Cedar $25–$40; pine $20–$40; redwood $40–$50 per sq ft[1] |
| Typical buyer | Louvered roofs, low-maintenance yards | Budget louvered kits, windier sites | Classic look, custom sizes, DIY |
For most people who want a roof that opens and closes, an aluminum louvered kit is the low-maintenance default. For a classic open-beam look or a custom size, wood (or a bracket system like Toja Grid with your own lumber) gives you the most flexibility. Whatever you choose, compare its wind and snow ratings against your address (see below). This is where many kits fall short.
Aluminum vs steel vs wood
Aluminum
Aluminum doesn't rust, and a powder-coated finish needs little more than washing. It's the most common material for louvered kits. Mirador, Paragon and Purple Leaf all sell aluminum louvered models[3][4][5]. Aluminum is lighter than steel, so strength comes from the profile: post and beam size and wall thickness. Purple Leaf, for example, advertises a 4.33-inch crossbeam on one model and a 1.5mm column wall[5]. Compare those numbers, not just the word "aluminum."
Steel
Steel is stiffer and heavier, and it's usually cheaper for the same size. Backyard Discovery's Sarasota louvered pergola uses galvanized, powder-coated steel posts and anchoring plates[6]. The weak point is the coating. Once it chips or scratches, steel can rust, especially near the coast or where sprinklers hit it. Inspect it once a year and touch up any damage.
Wood
Wood is the traditional choice and the easiest to customize. Cedar resists decay naturally. Yardistry's 12 × 12 pergola uses 6 × 6 posts and FSC-certified cedar with a factory stain[8]. Pressure-treated pine is cheaper. Use lumber rated for ground contact anywhere wood touches soil or concrete. Wood needs re-staining or sealing, and its warranties are often short. Yardistry's gazebo manual lists one year on materials and workmanship and five years on lumber against rot and decay, with maintenance required[8].
Hybrid: steel brackets, your lumber
Toja Grid sells powder-coated steel brackets made in Canada that turn standard 4 × 4 or 6 × 6 lumber into a pergola of nearly any size. You buy the wood locally, and the kits don't include lumber or anchoring hardware. The brackets carry a 5-year manufacturing-defect warranty[7]. It's a good middle path if you want wood with less cutting and joinery.
Open, louvered or solid roof
- Open beams or slats: partial shade, no rain protection, the lowest cost and wind load, and nothing on the roof for snow to pile on. Add a shade sail or retractable canopy if you need more cover.
- Louvered (adjustable): aluminum or steel blades that tilt open for light and close for shade and rain, usually with gutters that drain down the posts[5][6]. Manual crank or motorized. HomeGuide puts a 12 × 12 at $6,500–$15,800 installed for manual and $7,900–$18,000 for motorized[2]. Closed louvers shed most rain, but they aren't a sealed roof, and makers tell you to open them in high wind or snow[3][5].
- Solid (hardtop): metal or polycarbonate panels. These are technically closer to a gazebo or patio cover, they carry snow and wind load all the time, and they're more likely to need a permit.
A motorized roof, lights, fans or outlets add electrical work. Backyard Discovery builds outlets and USB ports into some posts, but you still need a power source[6]. Outdoor wiring should be done by a licensed electrician under a permit.
Wind and snow ratings: what they mean where you live
Kit makers publish a wind rating in mph and a snow load in pounds per square foot (psf). Here's what several current product pages list:
| Model (maker's page) | Frame | Wind | Snow | Conditions the maker attaches |
|---|---|---|---|---|
| Mirador 111DA 10×10 | Aluminum | 102 mph | 26.6 psf | With professional assembly and anchoring[3] |
| Paragon Suprema | Aluminum, steel bases | 82 mph | 19 psf | Anchor plates[4] |
| Paragon Lugano | Aluminum | 82 mph | 17 psf | [4] |
| Purple Leaf louvered (Athena listing) | Aluminum | 72 mph | 13 psf | Secured with expansion screws on a hardened floor; open louvers in extreme weather[5] |
| Backyard Discovery Sarasota 10×10 | Galvanized steel | 100 mph | 2,000 lb or 12 in of snow (about 20 psf over 100 sq ft) | "Pro-Tect" tested, anchored per instructions[6] |
Two cautions. First, these are manufacturer claims, usually conditional on anchoring, with no common third-party test standard behind them. Mirador's own FAQ lists different numbers (13.8 or 17.7 psf, and 73 or 82 mph, depending on model) from its product spec block[3], so confirm the rating for the exact model and size you're buying. Second, compare them to your local design loads:
- Wind: building codes use the ASCE 7 basic wind speed for your location, a 3-second gust measured 33 feet above open ground. For ordinary buildings it's on the order of 105–115 mph across much of the inland U.S., and much higher along the hurricane coast. FEMA's ASCE 7-22 fact sheet cites Risk Category II speeds of 146 mph for Mobile, Alabama, and 152 mph for Destin, Florida[10][11]. A 72–102 mph kit rating is below those design speeds, so in windy or coastal areas, treat a kit as a seasonal shade structure unless it's engineered and permitted for your site.
- Snow: look up your ground snow load in the free ASCE Hazard Tool by entering your address[10]. In snowy regions it can be several times the 13–27 psf ratings above, and drifting next to a house wall adds more. In those climates, choose open beams or louvers you can leave open, clear heavy snow, or buy a structure engineered for your load.
Hurricane zones (Florida and the Gulf and Atlantic coasts)
In South Florida's High-Velocity Hurricane Zone (Miami-Dade and Broward), cities' pergola permit checklists ask for a current Miami-Dade Notice of Acceptance (NOA), a Florida Product Approval, or sealed engineered plans[13]. Some louvered systems, such as Azenco's R-Blade, hold a Miami-Dade NOA[13]. Most online kits don't, so ask before you buy. Elsewhere on the coast, check your county's wind speed in the ASCE tool and ask the building department what it needs.
Snow country (Northern tier, Mountain West, Great Lakes snow belts)
Prefer louvered roofs you can leave open all winter, or open beams. A closed louvered roof is meant to carry some snow. Purple Leaf markets its 13 psf rating as holding snow off your furniture[5], but a big storm can exceed that quickly. Footings matter more here too (see below).
Anchoring and footings
Nearly every kit's wind rating assumes it's bolted down correctly. Mirador and Purple Leaf both tie their ratings to anchoring, and Purple Leaf specifies expansion screws into a "hardened floor"[3][5]. Common setups:
- Existing concrete patio: a pergola is only as good as the slab under it. A thin or cracked patio may not hold anchors in a gust. Many installers pour separate footings under each post.
- Concrete footings in soil: piers under each post, with depth set by local code. In cold climates that often means below the frost line, to prevent frost heave from lifting and racking the frame. Ask your building department.
- Wood deck: the deck framing has to carry the uplift and lateral loads. Attach to joists and blocking with through-bolts, not to deck boards. An engineer or deck builder should check heavy louvered units.
- Call 811 before you dig. It's free, and utilities will mark buried lines. Most states require a few business days' notice[12].
Permits, HOAs and setbacks
Permit rules are local, but most U.S. cities start from the International Residential Code (IRC). Under IRC section R105.2, one-story detached accessory structures up to 200 square feet can be exempt from a building permit[9]. Many cities apply that to freestanding open pergolas. Common reasons you'll still need a permit:
- It's attached to the house, where the detached exemption doesn't apply.
- It's over 200 sq ft or has a solid roof.
- It has electrical work (a motorized roof, lighting, outlets), which needs an electrical permit.
- Your city or county amended the exemption. Many have.
Even when no building permit is required, zoning setbacks (distance from property lines), easements, flood zones and HOA rules still apply. Purple Leaf's listing specifically tells buyers to check HOA approval before purchasing, because many associations regulate louvered pergolas[5]. Get approvals in writing before you order a kit that may be non-returnable once it's opened.
What it costs
HomeGuide's national estimates:
| Option | Installed cost |
|---|---|
| Prefab pergola kit plus labor | $1,450–$5,750[1] |
| Custom wood pergola, 12 × 12 | $4,300–$9,400[1] |
| Manual louvered roof, 12 × 12 | $6,500–$15,800 ($45–$110 per sq ft)[2] |
| Motorized louvered roof, 12 × 12 | $7,900–$18,000 ($55–$125 per sq ft)[2] |
| Labor to assemble a kit under 16 feet | $600–$1,500[1] |
Hidden costs to budget for: footings or a new slab, anchors (sometimes sold separately), permits and HOA fees, electrical work for motorized roofs and lights, and freight. Big louvered kits ship as several hundred pounds of crates. Mirador lists its 10 × 10 at 308 pounds, and Backyard Discovery lists the 10 × 10 Sarasota at about 482[3][6]. Plan for at least two to four people on assembly day[5].
Planning a hot tub under it? Check the roof clearance and the electrical disconnect location first. See the hot tub buying guide.
Selling or flipping soon?
- A permitted, well-anchored pergola stays with the house and defines an outdoor room in listing photos.
- Exterior projects led the 2025 Cost vs. Value report; a full backyard patio recouped only about 46%, so a mid-priced kit is the better pre-sale buy.
- Keep the permit, HOA approval and the kit's wind and snow ratings for the buyer.
- The Backyard Discovery Sarasota gives the louvered look at a mid price; custom builds rarely pay back on a short timeline.

FAQ
Is an aluminum or steel pergola better?
Aluminum doesn't rust and needs the least upkeep, which makes it the usual pick for louvered roofs and coastal areas. Steel is stiffer and often cheaper, but it can rust where the powder coat is chipped. Compare the specific model's wind and snow ratings rather than the material alone.
Do I need a permit for a pergola?
Often not for a small freestanding one. The model IRC exempts one-story detached accessory structures up to 200 square feet from a building permit, but attached pergolas, larger or solid-roof structures, electrical work and local amendments commonly require permits. Zoning setbacks and HOA rules still apply.
What wind rating should a pergola have?
Kit ratings typically range from about 70 to 100 mph, while building-code design wind speeds are around 105–115 mph across much of the inland U.S. and higher on the coast. Look up your address in the ASCE Hazard Tool. In high-wind or hurricane areas, use an engineered, permitted structure or treat a kit as seasonal.
Can a louvered pergola hold snow?
Only up to its rated load, which is often about 13 to 27 psf on current kits. That can be exceeded in snowy regions. Makers tell you to open the louvers in heavy snow, and some owners leave them open all winter.
Can I put a pergola on my existing patio or deck?
Sometimes. The slab or deck framing has to hold the anchors against wind uplift. Thin or cracked patios and deck boards alone usually aren't enough, so many installers pour footings under each post or bolt into reinforced deck framing.
How much does a louvered pergola cost installed?
HomeGuide estimates $6,500–$15,800 for a 12 × 12 manual louvered roof and $7,900–$18,000 for a motorized one, installed.

Wind and snow rating check
Enter your design wind speed and ground snow load from the ASCE Hazard Tool, then see which kits are rated for them.
How it works: Compare each kit's published wind (mph) and snow (psf) rating with your site numbers. Ground snow is not the same as roof snow load, and kit ratings assume the maker's anchoring.
Estimate only; confirm with your installer or the manufacturer.
