18X20 Carports

$1,395 to $3,385 — same 18×20 carport, same footprint, wildly different prices. Most sellers flash the low number to reel you in, then stack on $800 for installation and $500 for delivery until that $1,395 quote is really $3,200 before you even pick a color.

Worse than overpaying is what you get for it: 29-gauge frames that buckle under snow, roofs that pool water in heavy-precipitation zones, and "professional installation" from crews who skip proper anchoring. That's not a bargain — it's an expensive repair bill waiting to happen.

We sell 18×20 carports rated for 130 mph winds, with delivery and installation already built into the price, no hidden fees or surprise add-ons. Call us at (866) 941-4072 or schedule a free consultation and we'll break down exactly what you're paying for.

An 18×20 carport gives you 360 square feet of covered space — enough for two standard vehicles or one larger rig with room left over for storage. That 18-foot width breaks down to roughly 9 feet per vehicle when you're parking two side-by-side, and 20 feet of length handles most sedans, compact SUVs, and mid-size trucks comfortably.

Your average sedan runs 15–16 feet long and about 6 feet wide. Compact SUVs? Typically 15–17 feet long and 6–6.5 feet wide. Here's how that plays out in real setups:

Two-Vehicle Setup: Two sedans or compact SUVs side-by-side, with roughly 2–3 feet of clearance between them and 3–4 feet of breathing room at the front or rear.

Single Large Vehicle Plus Storage: One RV (up to 20 feet), a boat with trailer (18–20 feet total), or a full-size truck — plus 6–8 feet left for lawn equipment, tools, or recreational gear.

Workshop or Multi-Use Space: One vehicle alongside a workbench area, or skip the vehicles entirely and use the whole footprint for storage and projects.

You'll want about 2 feet of clearance on each side of a vehicle for comfortable door opening. With 18 feet of width and two vehicles, that leaves 2.5–3 feet of combined clearance per car. Tight? A little. If you regularly haul wide loads or just want more elbow room, take a look at our 20×20 carports instead.

Height matters too. Our standard 18×20 carports start at 6-foot leg height, but we go up to 14 feet. Storing a lifted truck, tall van, RV, or boat? Measure your vehicle's total height and tack on at least 1–2 feet of clearance.

The 20×20 gives you an extra 80 square feet for roughly $200–$400 more. Go with the 20×20 if you've got two full-size trucks or SUVs, want workspace around your vehicles, or might add enclosed sides down the road. The 18×20 makes more sense if you have two compact-to-midsize vehicles, one large vehicle with modest storage needs, or you're working within a tighter budget.

Price swings come down to roof style, material gauge, customization options, and whether delivery and installation are actually included or tacked on later.

The single biggest factor? Roof style. A regular (flat) roof is cheapest but offers poor water runoff — and honestly shouldn't be used anywhere with real rain or snow. An A-frame horizontal roof runs $300–$500 more with better drainage. A vertical roof — panels running vertically from peak to edge — adds $600–$900 but is non-negotiable for high-precipitation areas.

Material gauge is the second big cost driver. Our standard 14-gauge steel frame handles most weather conditions and is certified for 130 mph winds and 35 psf snow loads. Stepping up to 12-gauge steel adds $200–$400 but delivers extra strength for extreme weather zones.

At this price point, you're typically looking at a regular roof carport with 14-gauge framing and 29-gauge steel panels:

• 14-gauge galvanized steel frame
• 29-gauge steel roof and trim panels
• Standard 6-foot leg height
• Basic color options (usually 3–5 choices)
• Engineered certification for wind and snow loads

What's often not included at those advertised low prices: delivery (add $300–$600) and installation (add $500–$1,200). We include both — completely free. That's $800–$1,800 in real value that competitors charge separately.

This is where you get an A-frame horizontal or vertical roof and a wider selection of finishes:

• Vertical or A-frame roof style for superior drainage
• 12–14 gauge framing options
• Extended color palette (15+ colors)
• Height options from 6 to 12 feet
• Enhanced certifications for specific regional requirements

Vertical roof carports last 30–40% longer in high-precipitation climates compared to regular roofs. Why? Water and snow shed immediately instead of pooling and stressing panels over time.

At the top end, you're adding enclosures, garage doors, and extra height:

• Partial or full enclosures (sides and ends)
• Garage door installation (one or two doors)
• Extra-tall configurations (12–14 feet) for large vehicles
• Premium color combinations and trim packages
• Gutters and downspouts for water management

An enclosed 18×20 carport with a garage door is basically a metal garage — real security and weather protection that an open carport simply can't match.

Every quoted price includes delivery and professional installation to all 50 states. When we say an 18×20 vertical roof carport costs $2,495, that's the complete price. Delivered to your property. Installed by certified crews. Done.

Now compare that to competitors advertising "$1,395" while charging separately for delivery ($300–$600), installation ($500–$1,200), anchors ($100–$300), and roof upgrades ($400–$800). That "$1,395 carport" actually runs $2,595–$3,295. Funny how that works.

We provide completely free delivery and professional installation to all 50 states, with most jobs wrapped up in 4–6 hours — a single day.

After you place your order, we schedule delivery based on your location. Lead times run from 1–2 weeks for nearby states up to 3–4 weeks for more remote areas. You'll get a specific delivery window, and we'll call 24–48 hours ahead to confirm timing.

1–2 Week Delivery: Most of Texas, Oklahoma, Arkansas, Louisiana, and nearby southern states.

2–3 Week Delivery: Southeast, Midwest, and mid-Atlantic states — Florida, Georgia, Tennessee, Missouri, Illinois, Ohio, Pennsylvania, and surrounding areas.

3–4 Week Delivery: Western states (California, Oregon, Washington, Nevada, Arizona, Colorado), northern states (Montana, North Dakota, Minnesota, Wisconsin, Michigan), and New England.

4–6 Week Delivery: Alaska and Hawaii due to shipping logistics.

We handle installation. You handle site prep:

Level Ground: Your installation area should be relatively level — within 3–4 inches across the 18×20 footprint. Grass, gravel, dirt, or concrete all work, but the surface needs to be reasonably flat.

Access: Our delivery truck needs a clear path to your site. Make sure gates are wide enough (at least 10 feet), overhanging branches are trimmed, and nothing's blocking the way.

Utilities: Mark any underground utilities — electric, gas, water, septic — in the installation area. Call 811 for free utility marking at least 3 days before installation.

Permits: Check with your local building department about permit requirements. Many counties require permits for structures over 200 square feet. We provide engineered drawings and certifications for your permit application.

HOA Approval: Living in a community with a homeowners association? Get written approval before ordering. Trust us on this one.

A standard open 18×20 carport takes 4–6 hours to install. Our crew verifies the site, lays out the footprint, assembles the frame, installs roof panels, and anchors everything according to engineered specifications for your local wind and snow loads.

Can I install an 18×20 carport myself? It's technically possible, but we don't recommend it. Professional installation means proper anchoring, code compliance, and valid warranty coverage. Our free installation takes this worry off your plate entirely.

What's the best roof style for my area? Vertical roofs are a must for areas with heavy snow or rain. Regular roofs work fine in dry climates with minimal precipitation. A-frame horizontal roofs split the difference for moderate weather.

How long does an 18×20 carport last? With proper installation and maintenance, our carports last 20–30 years. Vertical roof models in harsh climates typically outlast regular roofs by 30–40%.

Do I need a concrete foundation? No. We anchor to ground using mobile home anchors or concrete footings. Concrete slabs are great but not required.

Can I enclose my carport later? Absolutely. Most customers start open and add sides, ends, or garage doors later as budget allows.
