The Ultimate Guide To Metal Carports
A simple, practical guide to choosing the right size, height, and options for your vehicle, RV, or equipment — plus what to know before installation.
Choosing The Right Size
A common starting point for a single vehicle is 12' × 20'. That’s usually enough space for one car, SUV, or pickup — and some tool or storage room. If you’re covering two vehicles or want more room to open doors comfortably, most homeowners step up in width.
Quick tip: Measure your vehicles first — including roof racks, ladders, and rooftop A/C units — and leave extra space for door opening.
12' Wide
Fits 1 car, truck, SUV, or a single boat.
18' Wide
Good for 2 compact cars or 1 small RV / trailer.
20' Wide
Common choice for 2 mid-size vehicles or car + small boat.
22' Wide
Fits 2 full-size vehicles with better door-opening room.
24' Wide
Popular “room to grow” size: 2 full-size vehicles, or mixed setups (truck + trailer).
26'–30' Wide
Triple-wide coverage for 3 mid-size cars, trucks, or SUVs.
For commercial yards, farms, and large equipment, wider buildings may be available — but the right width depends on what you’re covering and the layout you need.
Before Installation: Your Site
The most common install issues come from the ground, not the building. The area should be level and able to drain water away.
- Level ground matters: Try to keep the surface within about 1–2 inches of level across the full footprint.
- Concrete is common: A 4" slab is typical. Some enclosed garages may need thicker edges depending on your setup.
- Drainage: Avoid low spots where water can pool under the structure.
Airflow & Moisture (Simple Version)
Metal buildings can trap warm air and moisture, especially when fully enclosed. Good airflow helps reduce “sweating” on metal panels.
- Enclosed garages: Vents and/or insulation can help reduce moisture buildup.
- Storage use: If you’re storing tools, boxes, or vehicles long-term, plan for airflow.
Fully Enclosed Garage Options
If you’re building a fully enclosed metal garage, you can add options that improve access, security, light, and overall usability. Exact options vary by package.
Doors
Roll-up doors in multiple sizes, plus walk-in doors (solid, heavy-duty, or diamond window styles). Optional seals can help reduce light and wind-driven rain around the door opening.
Windows & Daylight
Add windows for natural light. Some packages offer translucent panels or skylights (sizes vary by supplier).
Insulation
Choose roof-only, walls, ends, or full insulation. Helpful for comfort and reducing moisture, especially in enclosed buildings.
Add-On Features
Popular upgrades include wainscoting (two-tone look), extended gables, base rails, or a lean-to side cover for extra storage or workspace.
Colors & Finish
Choose wall, roof, and trim colors. Color-matched screws are available on many builds for a cleaner exterior look.
Anchors
Anchors depend on your surface: concrete, asphalt, or ground/dirt. We match the anchor type to your install surface and site conditions.
Permits & Local Rules
Many permanent carports and garages require permits in California, especially enclosed structures. Some neighborhoods may also require HOA approval. If you tell us your city and county, we can help you plan the right approach for your area.
