20X30 Carports

Two dealers, two prices for what looks like the exact same 20×30 carport. One says $4,500. The other wants $7,200 for the same size, the same steel, and the same roof style you asked for.

Guess wrong on that gap and you're either paying for features you don't actually need, or watching your second vehicle sit half-covered through another storm because you sized down just to save money you didn't really save in the end.

We sell 20×30 carports with transparent pricing breakdowns, honest sizing and roof guidance, and professional installation across 46 states, so you know exactly what you're paying for before you spend a single dollar.

A 20×30 carport gives you 600 square feet of covered space — enough for two standard vehicles with room to spare, or one small RV, boat, or work truck alongside some equipment storage.

Two mid-size sedans (15–16 feet long, 6 feet wide) fit easily with walking space between them. Two full-size pickups (18–20 feet long, 6.5–7 feet wide) fit with solid protection. You'll still have roughly 3–4 feet between vehicles when parking two standard cars, which means you can actually open your doors and move around without that awkward sideways shuffle.

For most two-vehicle households, a 20×30 carport hits the sweet spot. Park two sedans, two SUVs, or a sedan-and-truck combo — and still have enough room for wall-mounted storage, a workbench along one side, or lawn equipment tucked in the corners. That covered storage pays off long-term, too: proper vehicle storage extends paint life by 40-60% compared to constant sun exposure (NIH).

That 20-foot width makes a real difference. Unlike a cramped 18×20 where you're squeezing between vehicles, this size gives you genuinely usable space.

Small Class B RVs and most Class C RVs up to 28–29 feet long fit comfortably within the 30-foot length. Boats on trailers — bass boats to mid-size pontoons — typically run 20–24 feet total including the trailer.

Height is the measurement people forget about. Standard 8-foot or 10-foot leg heights work fine for boats and smaller RVs, but plenty of Class C RVs and truck campers need 12-foot or 14-foot legs. We always recommend at least 12–18 inches of vertical clearance above your RV's highest point (usually the AC unit on top).

Standard carport leg heights come in 8, 10, 12, and 14-foot options:

• 8-foot legs: Standard cars, sedans, most SUVs
• 10-foot legs: Full-size trucks, vans, small boats on trailers
• 12-foot legs: Box trucks, small RVs, tall equipment, larger boats
• 14-foot legs: Class C RVs, fifth-wheels, commercial vehicles

Each 2-foot height increase adds roughly $400–$600 to your total cost. Worth it for proper clearance — and a lot cheaper than scraping your RV's AC unit.

A 20×30 metal carport typically runs between $5,200 and $9,800 depending on roof style, height, and enclosure options. Our pricing includes free delivery and professional installation.

A basic 20×30 carport with a rounded roof, standard 8-foot legs, and no sidewalls starts around $5,200–$5,800 in most states. That gets you overhead protection from sun, rain, and snow.

Stepping up to an A-frame roof adds about $600–$900, bringing the total to $5,800–$6,700. Better water runoff than rounded roofs, and it handles moderate snow loads more effectively.

Our premium vertical roof option adds $900–$1,400 over the base rounded roof price, putting a basic vertical roof 20×30 at $6,100–$7,200. Vertical roof panels shed snow and water 40% more efficiently than horizontal or rounded panels — a meaningful difference if you're in a wet or snowy climate.

Sidewalls turn your carport from basic overhead coverage into real weather protection:

• One sidewall: $400–$800
• Two sidewalls: $800–$1,600
• Three sidewalls (partially enclosed): $1,200–$2,400
• Four sidewalls (fully enclosed): $1,500–$3,000

We tell most customers to go with at least one or two sidewalls. Even a single sidewall on the prevailing wind side stops rain and snow from blowing onto your vehicles. Yes, sidewalls add 25–30% to your base cost — but they can prevent thousands in wind-driven rain damage over the life of the structure.

A fully enclosed 20×30 structure with vertical roof, four sidewalls, and garage doors is essentially a functional garage. Total investment: $8,500–$11,500 depending on door configuration and height.

This option includes vertical roof for maximum durability, four enclosed sides, one or two garage doors (9×8 standard size), walk-in door option, and window placements for natural light.

Expect 10–20% price swings between states. Local labor rates play a role, along with building code requirements (some states require engineered certifications that add $200–$400) and material shipping costs based on distance from our manufacturing partners' facilities.

We provide itemized quotes showing exactly where your money goes — materials, delivery to 46 states, professional installation, and anchoring to your prepared site. No mystery line items.

We recommend vertical roofs for 20×30 carports in most climates because of superior water and snow runoff, longer lifespan, and stronger structural integrity.

Vertical roof panels run from peak to edge, creating channels that actively shed water, snow, leaves, and debris. That orientation pays off in harsh weather: vertical panels reduce snow accumulation by 40-60% compared to horizontal panels.

The cost difference? About 10–15% more than rounded roofs ($900–$1,400 additional for a 20×30). But you make that back in longevity — we see vertical roofs lasting 25–30 years with minimal maintenance versus 15–20 years for rounded roofs.

Best for: Areas with regular snow, heavy rain, or extreme weather. Really, any climate where you want maximum durability and the least hassle.

A-frame roofs give you a traditional peaked design with horizontal panels and enclosed eaves. The peaked center handles water runoff well, and those enclosed eaves add structural rigidity.

Pricing lands between rounded and vertical — expect $600–$900 more than a rounded roof. You get better weather performance and that classic garage-style look.

Best for: Moderate climates with occasional snow or heavy rain. Great for customers who want better-than-basic performance without paying the premium price.

Rounded roofs use a curved design with horizontal panels. Most economical option, which makes them popular for basic overhead coverage in mild climates.

On a 20×30 carport, you're saving $900–$1,400 compared to vertical roofs. The tradeoff is real though — horizontal panels accumulate snow, leaves, and debris more readily. Typical lifespan runs 15–20 years with proper maintenance.

Best for: Mild climates with minimal snow. Budget-conscious buyers who need straightforward overhead protection.

We offer 16+ color choices, multiple height options (8, 10, 12, and 14-foot legs), flexible sidewall configurations, and various door and window placements for your 20×30 carport.

We stock 16 standard colors — everything from neutral tones (white, beige, tan, gray) to bolder options (red, blue, green, brown). Roof and trim can be different colors, and a lot of customers go with a neutral roof paired with colored trim to match their home.

Standard colors come included in base pricing. Premium or custom colors may add $200–$400.

Popular combinations we see: white roof with white trim (reflects heat beautifully), gray roof with white trim (modern look, hides dirt), and tan roof with brown trim (blends perfectly with rural settings).

You can add sidewalls to any combination of sides. Where you put them matters:

One sidewall: Place it on the prevailing wind side (typically west or northwest). Blocks the majority of wind-driven rain and snow.

Two sidewalls: Install on both ends (the 20-foot sides) to create a covered breezeway effect. Vehicles enter from the long sides while weather stays blocked from the ends.

Three sidewalls: Enclose both ends and one long side, leaving the front open for easy access. Excellent weather protection with convenient entry.

Four sidewalls: Full enclosure — your carport becomes a garage. You'll need door installation.

Once sidewalls go up, you'll want doors and windows for access and light:

• Garage doors: 9×8 feet (standard), 10×10 feet (oversized), single or double door configurations
• Walk-in doors: 36-inch standard entry doors with locksets
• Windows: 2×3 or 3×3 foot windows for natural light
• Roll-up doors: Commercial-style overhead doors for frequent access

Garage door installation adds $800–$1,400 per door. Walk-in doors run $300–$500. Windows are $150–$300 each.
