A 20x20 patio cover offers a generous 400 square feet of shade—perfect for outdoor entertaining, relaxing, or creating a protected living space. But how much does a structure like this actually cost? The answer depends on material, style, installation method, and additional upgrades. Below, we break down the average cost range for a 20x20 patio cover, focusing on aluminum and Alumawood options, with comparisons to traditional wood.

Average Cost of a 20x20 Aluminum Patio Cover

Basic Aluminum Structure

Aluminum is one of the most cost-effective materials for patio covers. It’s durable, lightweight, rust-resistant, and designed to last for decades with minimal maintenance. A basic 20x20 aluminum patio cover typically costs between $6,000 and $9,500, depending on style and finish.

This estimate usually includes:Standard posts and beamsBasic color optionsSolid or lattice-style roofProfessional installation

These structures are ideal for homeowners who want a clean, simple shade solution with long-term durability.

Alumawood Upgrade

Alumawood is a type of aluminum patio cover with an embossed woodgrain texture and a baked-on finish that mimics real wood. It offers the visual warmth of timber with the low-maintenance strength of aluminum. For a 20x20 Alumawood patio cover, you can expect to pay between $8,000 and $12,000.

Alumawood covers may cost more than standard aluminum but offer better aesthetics, HOA-friendly looks, and longer-lasting finishes.

Additional Features That Increase Cost

Adding extra components or upgrades can push the price higher. These include:Electrical wiring for fans or lights (+$500 to $1,500)Decorative columns or beamsInsulated roof panelsCustom paint colorsGutters and downspouts

Each of these can add style and function—but also increase the overall project cost.

Traditional Wood Patio Cover Costs

Upfront Material and Labor

Wood covers bring a natural, rustic charm that’s hard to replicate. However, wood is more expensive upfront and over time. A 20x20 wood patio cover typically ranges from $10,000 to $16,000, depending on the type of wood, design, and contractor.

Common wood materials include:Pressure-treated pine (least expensive)Redwood or cedar (more premium)Custom milled or painted beams (highest cost)

Wood also requires more labor, especially when it comes to staining, sealing, and precision cutting. That can drive up both materials and installation fees.

Long-Term Maintenance Costs

Wood may be more expensive in the long run due to its ongoing maintenance costs. You’ll likely need to:Re-stain or seal every 2–3 yearsReplace warped or cracked boardsWatch for termite damage

These recurring tasks can add hundreds—if not thousands—over the lifespan of your patio cover.

Cost Comparison: Alumawood vs Wood Feature Alumawood (20x20) Wood (20x20) Initial Cost $8,000–$12,000 $10,000–$16,000 Maintenance Low High Lifespan 20–30 years 10–20 years Pest Resistance Excellent Poor Looks Like Wood Yes Yes (it is) Custom Finishes Limited options Highly customizable  

Alumawood delivers long-term savings through its durability and reduced maintenance requirements. Wood offers more customization options but at a higher cost in terms of materials, time, and upkeep.

DIY vs Professional Installation

Doing It Yourself

For experienced DIYers, building a 20x20 aluminum patio cover can save on labor costs. A basic DIY kit may cost between $3,000 and $6,000, excluding tools, concrete footings, and permits.

Keep in mind:City permits may be requiredImproper installation can affect structural safetyElectrical components (like lights or fans) require licensed professionals

Professional Installation

Hiring a licensed contractor ensures:Local code complianceWarranty-backed workStructural integrityHOA approval support (if applicable)

While it increases cost, professional installation provides peace of mind and a polished final result.

Permit and Inspection Fees

In many California cities, including Temecula, Murrieta, and Menifee, a permit is required for patio covers. Fees typically range from $250 to $750, depending on your city’s regulations and the complexity of the build.

If your cover includes electrical wiring or is attached to the home, additional permits or inspections may be required.

Final Thoughts on Budgeting

A 20x20 patio cover can be a significant upgrade and the right material makes all the difference.Choose aluminum for durability and affordability.Choose Alumawood if you want the look of wood without the upkeep.Choose traditional wood only if you’re prepared for higher long-term maintenance.

Set a realistic budget based on your specific needs, then work with a local installer who understands local building codes, climate conditions, and any applicable HOA requirements. A well-built patio cover isn’t just an outdoor feature—it’s an investment in comfort, value, and lifestyle.
