How Much Does It Cost to Cover a 20x20 Patio? Pricing

Covering a 20x20 (400 sq ft) patio typically runs $1,600 to $7,200 for the patio surface itself, and an additional $2,000 to $20,000+ if you're adding a patio cover like a pergola, attached roof, or screened enclosure. Most homeowners doing both end up spending somewhere between $8,000 and $20,000 combined, depending on the surface material, cover type, site conditions, and where they live. If you just want a ballpark before diving in: a standard concrete patio with a mid-range pergola on a flat, accessible lot in a mid-cost region runs roughly $10,000 to $14,000 installed.

Quick cost snapshot: 20x20 patio at a glance

A 20x20 patio is exactly 400 square feet, which is a practical, common size for outdoor entertaining. Here are the installed cost ranges you'll run into for the most popular surface options, using low, typical, and high per-square-foot figures. "Installed" means materials plus labor unless noted otherwise.

And here are the installed cost ranges for common patio cover options over that same 400 square feet. These are cover-only costs and do not include the patio surface beneath them.

How to read these numbers

Every cost table you see on this site uses the same baseline assumptions so comparisons stay apples-to-apples. For the patio surface figures: the area is 400 square feet (20x20), concrete slabs assume a 4-inch thickness (the standard residential minimum per IRC guidelines), and all totals include a 4-inch compacted gravel base unless noted. Installed prices cover materials, labor, basic site prep on flat accessible ground, and standard finishing. They do not include permits, demolition of an existing surface, drainage upgrades, or complex grading.

For patio covers, the low end assumes a basic prefabricated or kit-style product with straightforward installation on an existing concrete or paver surface. The high end reflects custom-built structures, premium materials (cedar, aluminum systems, insulated panels), engineered footings, and full electrical rough-in for lighting or fans. Labor rates used in these estimates reflect a national mid-range of roughly $50 to $100 per hour for experienced contractors, which covers most U.S. markets outside of high-cost metros like San Francisco, Seattle, or New York City, where rates can run 20 to 40 percent higher.

Permit fees are excluded from all per-square-foot figures because they vary so widely: a simple patio in a rural county might cost $0 to $50, while an attached patio cover or screened room in a suburban municipality can require $200 to $800 in permits plus inspections. The timeframe these prices reflect is current as of 2025 to 2026, accounting for post-pandemic material cost normalization. Always treat these ranges as a starting budget framework, not a fixed quote.

Full line-item cost breakdown for a 20x20 project

Whether you're building from scratch or adding a cover to an existing slab, it helps to see exactly where the money goes. Below is a realistic line-item breakdown for a mid-range 20x20 patio project: a stamped concrete surface with an attached aluminum cover on a flat, accessible lot. Think of this as a sample estimate, not a quote.

The biggest driver of that total is almost always the cover choice. A gravel patio with a basic pergola might cost $3,000 to $5,000 all-in. A stamped concrete patio with a custom attached solid roof and ceiling fan could land at $25,000 or more. The surface and cover decisions are the two biggest levers you have on final cost, and they should be made together, not separately.

What each patio surface actually costs you

Standard concrete

At $4 to $18 per square foot installed, a standard 4-inch broom-finish concrete slab is the cheapest hard surface you can put down. Concrete Patio Cost, ConcreteNetwork (used as primary typical-rate source; low/high ranges supported by HomeAdvisor and regional estimator guides). reports low/typical/high installed rates of about $4 / $11 / $18 per sq ft, which equals $1,600 / $4,400 / $7,200 for a 20x20 (400 sq ft) standard 4" concrete patio with a 4" compacted gravel base, basic reinforcement, finishing, and typical site prep Concrete Patio Cost — ConcreteNetwork (used as primary typical-rate source; low/high ranges supported by HomeAdvisor and regional estimator guides).. The low end ($1,600 for 400 sq ft) reflects a straightforward pour on level ground with easy truck access. The typical range ($4,400) is closer to what most contractors charge after you factor in wire mesh or rebar, a proper gravel base, and a clean finish. Concrete is also the fastest to install: most 400-square-foot slabs go in within one to two days. The trade-off is it's the plainest looking option and it will crack over time, especially in climates with hard freeze-thaw cycles.

Stamped concrete

Stamped concrete adds color and texture to a standard slab, mimicking stone, brick, or wood. Costs run $8 to $28 per square foot installed, so a 20x20 project lands between $3,200 and $11,200. The lower end gets you a single-color, single-pattern stamp. The higher end involves multiple colors, complex patterns (like an ashlar or cobblestone design), borders, and a UV-resistant sealer. One gotcha people miss: stamped concrete needs to be resealed every 2 to 3 years to maintain appearance and prevent surface wear, adding roughly $300 to $600 per resealing for a 400-square-foot surface.

Concrete and brick pavers

Concrete pavers ($12 to $35/sq ft installed) and clay brick pavers ($10 to $30/sq ft installed) are both more forgiving than poured concrete: individual units can be lifted and reset if the base shifts, which is a real advantage in climates with ground movement. The 20x20 cost range is $4,000 to $14,000 for concrete pavers and $4,000 to $12,000 for brick. Brick patios carry significant regional price variation because most clay brick is manufactured in the Mid-Atlantic and Southeast, so freight costs add up fast in western states. Complex herringbone or basketweave patterns also add labor time, pushing contractor quotes toward the higher end.

Flagstone

Flagstone is the most expensive common patio surface. Dry-laid flagstone on a sand and gravel base runs $15 to $32 per square foot installed ($6,000 to $12,800 for 400 sq ft), while mortar-set or concrete-set installations climb to $25 to $45 per square foot ($10,000 to $18,000). The high cost is part stone price, part labor: fitting irregular natural stone pieces is genuinely time-consuming work. If you're interested in the detailed breakdown for a flagstone-only project, the 20x20 flagstone patio cost guide on this site covers stone types, regional sourcing, and base options in more depth.

Gravel and decomposed granite

Gravel or decomposed granite is the budget-friendly choice at $1 to $6 per square foot installed, or $400 to $2,400 for a 20x20 area. It drains naturally, installs quickly, and works well under a pergola or as a defined garden patio. The real costs are ongoing: it needs periodic topping-off, edging to keep it contained, and it's not ideal for furniture-heavy use. Still, for a back-corner entertaining area under a freestanding pergola, it's hard to beat the price.

Patio cover options and what they run

Attached solid roof

An attached patio roof (framed and tied into your home's existing roof or fascia) provides the most weather protection and the most permanent look. It runs $15 to $50 per square foot for a 20x20 cover, so $6,000 to $20,000. The wide range reflects roofing material choice (shingles vs. metal vs. insulated panels), whether a structural engineer is needed, and how complex the attachment point is. Almost every jurisdiction requires a permit for attached roofed structures, so budget $300 to $800 for that plus an inspection.

Freestanding pergola

A freestanding pergola runs $2,000 to $12,000 for a 20x20 structure ($5 to $30/sq ft installed). Kit pergolas made of vinyl or aluminum sit at the low end and can often be DIY-installed. Custom wood pergolas (cedar, redwood) or aluminum systems with built-in louvers sit at the high end. Pergolas provide partial shade and a defined outdoor room but don't shed rain unless you add a polycarbonate roof panel, shade sail, or retractable canopy. Pairing a pergola with a lower-cost gravel or concrete patio is one of the more cost-effective complete outdoor-room setups you can build.

Aluminum patio cover

Aluminum covers (also called patio covers or lattice-style aluminum panel systems) run $10 to $35 per square foot installed, or $4,000 to $14,000 for a 20x20. They're popular in the Sun Belt because they're low-maintenance, don't rot, and can be insulated for hot climates. An insulated aluminum cover with a flat-pan design can meaningfully reduce the heat radiating down onto the patio surface. These systems are often sold as engineered kits with manufacturer-specified footings, which simplifies the permitting process in many cities.

Screened enclosure

Screened enclosures run $5 to $30 per square foot for a 20x20 footprint ($2,000 to $12,000). They're a must-have in bug-heavy climates like Florida, the Gulf Coast, and parts of the Southeast. A basic screen room with an aluminum frame and fiberglass screen panels sits at the low-to-mid range. A full Florida-room-style enclosure with a solid roof section and no-see-um screen mesh sits at the top. Factor in a concrete slab or pavers if you don't already have one, and the total project cost adds up fast.

Retractable awning

A motorized retractable awning for a 20x20 patio runs $2,000 to $10,000 installed. Awnings are the most flexible option: you can extend them for shade and retract them when you want open sky. The trade-off is they don't handle heavy rain or wind well, and the fabric needs replacement every 8 to 12 years (typically $500 to $1,500 for the fabric alone). They work best as a supplemental cover rather than a primary weather shield.

Regional and site conditions that can change your price significantly

The numbers above assume a flat, easily accessible lot in a mid-cost U.S. market. Here's what happens when reality differs from that baseline, with real examples of how costs shift.

The two biggest regional surprises homeowners report are permit costs (which can easily add $500 to $1,200 in jurisdictions with strict review processes) and soil conditions (which you often don't know about until a contractor digs). If your yard has heavy clay, ask your contractor specifically whether the base estimate accounts for it. In some cases, the right answer is a thicker base; in others it's adding edge drainage or a French drain, which is its own cost line.

DIY vs. hiring a contractor: where you actually save money

Labor typically accounts for 40 to 55 percent of an installed patio or cover cost. So on a $8,800 concrete paver patio, roughly $3,500 to $4,800 is labor. That's real money if you have the skills, tools, and time to do it yourself. But DIY savings are not uniform across surface and cover types, and there are genuine risks to factor in.

The practical takeaway: gravel patios, paver patios, and kit pergolas are legitimately good DIY projects for a capable homeowner with a free weekend. Concrete pours, stamped concrete, and any cover that attaches to your home's structure are not. A bad concrete pour is essentially permanent, and an improperly attached patio roof can be a liability and a resale problem. Most contractors will also decline to warranty work they didn't install, so if you DIY the surface and later have drainage issues, the cover contractor won't fix it for free.

One underrated hybrid approach: DIY the patio surface (pavers or gravel) and hire out the cover. This can save $2,000 to $4,000 on the surface while keeping the structural work (which requires inspections in most jurisdictions) in professional hands.

How to choose: surface + cover decision framework

Most homeowners don't need the most expensive option. They need the right option for their climate, budget, and how they'll actually use the space. Use this checklist to narrow things down before calling a contractor.

One thing worth saying plainly: a patio and a deck are not the same trade-off for every homeowner. Patios are almost always cheaper than decks of the same size (a 20x20 wood deck typically runs $8,000 to $20,000 for the deck alone), they require no structural inspection in most jurisdictions, and they tend to hold up better under a covered structure. Decks make more sense when you have a raised first floor, poor drainage at grade, or you specifically want a wood surface. For most flat or gently sloping lots, a patio with a cover is the better value.

Getting quotes: practical next steps

Getting accurate quotes requires giving contractors accurate information. Before you call, have these details ready: the exact dimensions of your patio area, whether there's an existing surface to remove, your lot's drainage situation (does water pool near the house?), your desired surface and cover type (even a rough preference), and whether you'll need electrical for lighting or fans. Contractors who quote blind will often use a high number to cover unknowns. The more specific you are, the tighter and more comparable the quotes you'll get.

1. Get at least three written quotes for any project over $3,000. Prices can vary 30 to 50 percent between contractors for the same scope.
2. Ask each contractor to break the quote into line items: materials, labor, base prep, permits, and cleanup. A lump-sum quote is hard to compare.
3. Verify they'll pull the required permits. A contractor who suggests skipping permits to save money is a red flag.
4. Ask specifically about base depth and drainage plan. This is where corners get cut most often on patio installs.
5. For patio covers, ask whether the design requires an engineer's stamp. In wind zones or for attached structures, this is often required and should be included in the quote.
6. Check reviews specifically for the type of work you're hiring for. A contractor with great deck reviews isn't necessarily great at stamped concrete.
7. Ask about warranty terms: what's covered, for how long, and whether it transfers if you sell the home.
8. Time your project for off-peak seasons (late fall or early spring in most markets) where possible. Some contractors discount 10 to 15 percent to fill schedule gaps.

Cost-saving tips that actually work

• Choose standard concrete or concrete pavers over stamped or natural stone to cut surface costs by 30 to 60 percent with minimal functional difference.
• Supply your own materials (pavers, stone, gravel) if you have a truck or delivery access and the contractor is willing to do labor-only. This can save 10 to 20 percent on materials markup.
• DIY the base excavation and compaction before the contractor arrives. Some will discount labor if the prep work is already done correctly.
• Choose a kit pergola over a custom-built one. The appearance gap is smaller than most people expect, especially with quality vinyl or aluminum kits.
• Skip the electrical rough-in if you're not sure you'll use it. Adding it later costs $500 to $1,500 but is far cheaper than ripping up a finished structure to add it mid-project.
• Combine the patio and cover project with one contractor rather than hiring two separate crews. Coordination discount and single mobilization fee can save $500 to $1,500.
• Get quotes in late October through February when contractor schedules are lighter in most markets.
