20x20 Patio Cover Cost in Las Vegas (2026 Price Guide)
Straight answer: a 20x20 patio cover in Las Vegas costs $9,000 to $16,000 installed in 2026. That is 400 square feet of covered space, enough for a full dining set and a lounge area. Where you land in that range comes down to the material and the roof type, and a few local factors that national price guides miss.
20x20 cost by roof type
At 400 square feet, the roof system is the biggest lever on price.
- Alumawood solid roof: about $9,000 to $12,000. Full shade, a wood-grain finish, and no painting or warping. This is the most popular way to cover a 20x20 patio in the valley.
- Aluminum / 4K solid roof: about $10,000 to $13,500. Clean modern lines and wide clear spans that carry fans and lighting well.
- Insulated roof: about $12,000 to $16,000. A foam core drops the temperature underneath by up to 25 degrees, which is what turns a 20x20 slab into a room you actually use in July.
- Louvered / adjustable roof: $16,000 and up. Open the roof for a breeze, tilt it for filtered light, or close it for full shade and rain protection. The premium option, and worth it if you want control over the space year round.
A lattice or open 20x20 cover runs less, roughly $7,000 to $10,000, but it gives you filtered shade rather than the full shade most people want over a space that size.
The local factors national guides skip
Search “how much does a 20x20 patio cover cost” and you get a national average from a multi-state site. Las Vegas is a different job.
- Sun and wind load. A 20-foot span here has to hold up to 300-plus days of direct sun and monsoon-season wind. That means heavier posts and beams and real engineering, not a kit bolted to the wall.
- Clark County permitting. A cover this size needs a permit and stamped engineering. A legitimate quote includes both. If a bid is thousands cheaper and skips the permit, that is why, and it becomes your problem at resale.
- HOA approval. In Summerlin, Anthem, Mountains Edge, and most master plans, a 20x20 cover needs HOA sign-off on color and style. We handle that paperwork so the design gets approved the first time.
- Two-story attachment. Tying a cover into a two-story wall or a specific roofline adds labor and hardware. Common in newer valley builds, and it moves the number.
Insulated vs standard on a 20x20
This is the decision that matters most on a cover this big. A standard solid roof shades the space. An insulated roof shades it and keeps the air under it meaningfully cooler, because the foam core stops the roof from radiating heat down onto you. On 400 square feet in Las Vegas, that difference is the line between a patio you sit under in spring and fall and one you use all summer. If the budget is tight, insulate the seating half and run a standard roof over the rest.

How much does a 20x20 patio cover cost in Las Vegas?
A 20x20 (400 sq ft) patio cover in Las Vegas typically runs $9,000 to $16,000 installed in 2026. A solid Alumawood roof lands near the low end, an insulated roof sits in the middle, and a louvered adjustable roof runs to the top of the range and beyond.
Why is a 20x20 cover priced higher than two smaller covers?
A 20-foot span needs heavier beams and posts and more engineering to carry the load and handle Vegas wind. That structure, not just the extra square footage, is what raises the price on larger covers.
Does a 20x20 patio cover need a permit in Clark County?
Yes. A cover that size is well past the threshold for a building permit in Clark County and the City of Las Vegas. A proper installer pulls the permit and provides the engineering, and that cost belongs in the quote.
What is the most cost-effective way to cover a 20x20 patio?
A solid Alumawood roof gives you full shade, a wood-grain look, and no maintenance at the lowest cost of the solid options. Add an insulated roof only over the seating area if you want July-level comfort without insulating the whole span.
