Your boat is an expensive investment, and leaving it exposed to sun, rain, hail, or snow can cause damage that can be expensive to fix. That’s why a metal boat carport is one of the smartest ways to protect it. Unlike tarp or wooden shelters, metal carports offer year-round protection, long-lasting durability, and low maintenance.
But as soon as you start shopping, you see prices vary a lot. This guide helps you understand what affects the cost, from the type of steel used to local building rules. We have also covered recent pricing trends, smart planning tips, and how to get the best value for your money.
Average Cost of Metal Boat Carports in 2025
The price of a carport ranges between $15 and $25 per sq. ft., depending on size, material, and features. For example, a 32 x 32 metal vertical carport costs start at $20020. It has double/ ladder legs and double baserail with 29-gauge roofing and is certified for 170 mph.
You can upgrade this structure for higher strength and durability.
Key Cost Factors To Consider When Buying A Steel Boat Carport
Buying a steel prefab carport is a smart way to protect your boat from the weather. But, before you dive into pricing, it’s important to know what actually affects the cost. Here is a simple cost breakdown that shapes your final quote: –
1. Size And Dimension:
The bigger the carport, the more steel and labor it takes, so size directly impacts the final price of your boat cover. But, it’s not just square footage, you also need to think of –
- Width – Ensure there is enough room for the boat, trailer, and space to move around without getting any scratches. Note that boats with pontoons or wakeboard towers need extra clearance. For example, a 22 ft. pontoon boat is about 10 ft. wide.
- Length – A longer carport protects both ends of the boat from direct sun, rain, and snow. Most registered boats in the US are less than 26 ft. in length.
- Height – Your carport must be tall enough to clear the highest point of your boat, including Bimini tops or mounted gear.
NOTE: Carports for some boats, like sailboats, may cost more due to taller frames.
2. Metal Gauge and Type:
The steel and metals used in a carport affect both its strength and cost: –
- Steel Gauge – 14-gauge is the standard choice since it is lighter, cost-effective, and suitable for most climatic conditions. 12-gauge steel is thicker and stronger, costs more, but can handle heavy snow, strong winds, and gives stability to large structures.
- Frame Type – Tubular steel is lightweight, budget-friendly, and easy to install, making it ideal for personal use, while I-beam steel is heavy-duty, built for a wide span, and can bear extreme loads, making it ideal for commercial-grade shelter.
3. Roof Style:
The roof affects how well a metal cover can handle weather and how much it costs: –
- Regular – It’s economical, has rounded corners with horizontal panels, and is best for mild climates.
- Boxed Eave – It’s A-frame, has horizontal panels, comes in mid-price range, and is a great match for traditional home roofs.
- Vertical – It costs more compared to others, but is great for harsh weather conditions and gives extra durability to the structure. You need less frequent cleaning with a vertical roof as panels quickly slide off most dirt, debris, rain, and snow.
4. Anchoring and Foundation:
Your base matters just as much as your frame. You can choose an asphalt base, a concrete slab (most stable and long-lasting), a gravel pad, or simply leveled ground.
Match the anchors with the type of foundation, such as concrete bolts for a concrete slab, mobile home anchors for a gravel bed, and leveled ground.
TIP: Proper anchoring keeps your carport secure to the ground in bad weather.
5. Color and Finish:
- Standard Colors (included in the base price).
- Premium Finishes or Custom Colors (can add around $200 to $500 to the final price).
- Trending Color in 2025 – You can opt for earth tones like sage green, clay, and charcoal. Other colors like matte black and bronze as also great for a modern appeal.
- Wood-Look Powder Coatings (add warmth without high maintenance cost).
- Encloses and Gables – You can add partial or fully enclosed side panels, end walls, or closed gable ends for extra protection, but that requires most materials, so it increases the final cost.
NOTE: As per the International Residential Codes, a carport can be at most covered from two sides only. If it is covered from more than two sides, it will be referred to as a garage.
6. Certification and Wind/ Snow Ratings:
If you live near coastal areas, tornado alley, or snowy regions, certifications may be required for: –
- Meeting wind loads
- Meeting snow loads
- For stability under seismic activities
This can add costs between $500 and $1000, depending on specs, but it may help you with permits and insurance approval.
7. Installation – DIY Vs. Professional:
How are you planning to build your boat cover?
- DIY Kits – It saves on labor cost but requires tools, time, and a bit of muscle.
- Professional Installation – It can add about $1000 to $3000 to the total cost (depending on size and design complexity), but it will retain warranties and structural stability.
Other Factors That Can Affect The Metal Boat Cover Cost Are:
Don’t less some less obvious factors sneak in the final costs. Here’s what to watch for: –
1. Delivery:
Shipping isn’t cheap! The farther you are from the manufacturer or dealer, the more you will pay. For example, some remote areas or locations with limited access may cost more.
Watch Out For – Some vendors include delivery in the price, while others charge extra.
2. Site Preparation:
The ground must be ready before the steel frame carport goes up, which means: –
- Leveling the site to make sure the foundation sits evenly.
- Cleaning debris, rocks, or vegetation around the site.
- Laying a solid foundation.
NOTE: Site prep can cost a few hundred to a thousand dollars, depending on your land, the type of base you choose, and your location. A smooth, stable surface helps your carport last longer and stay anchored during storms.
3. Your Local Building Laws:
Many states and counties keep updating their building codes. So, you may need: –
- Permit before installing
- Certified metal boat carport with wind and snow ratings
- Thicker steel and extra anchors to meet safety rules
These changes can add to the cost, but they also ensure your carport is safe, legal, and built to last. We recommend checking with your local building department before buying.
