If you are trying to decide between a steel garage and a steel carport, you are not alone — it is a very common comparison. Both are metal car shelters, but they differ significantly in structure, security, customization, durability, and long-term value.
If you are wondering, “What is the difference between a carport and a garage?” — this guide is for you.
We will walk you through everything you need to know to make an informed decision based on your budget, climate, usage requirements, and the pros and cons of each option — especially when choosing a steel structure.
Protection Level: What Are You Really Shielding?
- Steel Garage: Fully enclosed and lockable. Protects vehicles and stored items from rain, snow, hail, wind, UV rays, rodents, and theft. Prevents frost and ice buildup in winter.
- Steel Carport: Open-sided with a roof for shade and basic shelter. Offers partial coverage from sun and precipitation, but does not block wind-blown rain or snow. No enclosed security.
Conclusion: A steel garage is the better option for year-round protection, especially in harsh or unpredictable climates
Budget & Cost: Garage vs Carport
- Steel Garage: Higher initial investment but adds property value and usable square footage. More materials, longer installation, and may require a slab foundation.
- Steel Carport: Usually comes with a lower upfront cost, using fewer materials and allowing for quicker setup. However, depending on the structure, especially with reinforced systems like Norsteel’s Rigid Frame Carports, the cost can be comparable to that of a fully enclosed garage.
Conclusion: Wondering about the cost of carport vs garage? Carports are generally more budget-friendly upfront.
Usage & Flexibility: More Than a Parking Spot
- Steel Garage: Multi-use potential — perfect for workshops, storage, home gyms, or hobby areas. Can include shelving, insulation, electricity, or a loft.
- Steel Carport: Primarily used for covering vehicles or creating basic shade. May also be used as a basic covered patio or outdoor workspace, but options are limited.
Conclusion: A garage provides greater flexibility if you want your space to serve multiple functions over time.
Storage: Secure or Exposed?
- Steel Garage: Fully enclosed, lockable space. Ideal for storing tools, bikes, equipment, lawn gear, and seasonal items securely.
- Steel Carport: No walls or doors. No framing or bracing on walls. Does not provide safe or weather-resistant storage beyond vehicle coverage.
Conclusion: A garage is the better solution if storage security is a priority.
Aesthetics & Property Value
- Steel Garage: Looks more permanent and polished in appearance. Can be designed to match existing structures and often increases property resale value.
- Steel Carport: Simpler appearance — clean and utilitarian. Offers less visual impact and does not typically enhance property value.
Conclusion: If appearance and resale value matter, a garage has a stronger impact.
Climate & Weather Resistance
- Steel Garage: Performs in every season. Fully enclosed protection from snow, wind, rain, and extreme temperatures. Can be heated or insulated.
- Steel Carport: Best for mild climates. It will not stop sideways snow, freezing rain, or cold winds.
Winter Survival
- Steel Garage: Keeps snow off your vehicle, prevents frost buildup, and reduces corrosion from salt and moisture.
- Steel Carport: Provides overhead protection but leaves vehicles exposed to blowing snow, freezing rain, and icy conditions.
Conclusion: A garage offers better performance in cold or snowy climates. Carports still leave you brushing off snow or de-icing.
Summer Heat
- Steel Garage: Shields vehicles and sensitive items from UV rays and extreme heat. Keeps gear and equipment cooler inside.
- Steel Carport: Offers shade and sun protection but does not regulate temperature or protect stored items.
Conclusion: Both provide shade, but only a garage offers controlled protection in hot conditions.
Wind & Storm Durability
- Steel Garage: Fully enclosed structure that can withstand strong winds and protect vehicles from debris, hail, and severe weather.
- Steel Carport: More exposed and vulnerable. Many steel carports on the market, especially tube-framed carports, can sway or rattle in extreme conditions and will not fully shield your vehicle during hail or heavy wind events. In some cases, wind can create a ballooning effect that lifts the carport and takes it away.
Conclusion: A garage provides full enclosure and maximum protection. However, for peace of mind, if you plan to build a carport in a storm-prone area, consider choosing Norsteel. With the right building system, such as the Norsteel Rigid Frame, your carport can withstand the test of time and deliver reliable durability even in the harshest weather conditions.
Insulation & Temperature Control
- Steel Garage: Can be insulated and temperature-regulated, turning it into a comfortable four-season space. Ideal for year-round projects or protecting sensitive gear.
- Steel Carport: No insulation, no thermal control. Standing under one in winter won’t feel much different from being outside.
Conclusion: Want comfort in cold or heat? A garage is the only option.
Humidity & Rust Prevention
- Steel Garage: Reduces exposure to moisture and temperature swings, helping to prevent rust and preserve tools, vehicles, and materials.
- Steel Carport: No control over humidity — moisture from rain or snow can still linger.
Conclusion: The best choice depends on what you need to protect. For sensitive tools and vehicles, a garage helps to extend the lifespan of your belongings.
Steel Strength & Durability
All carports are not created equally. Many carports on the market use lighter framing systems, which can make them less robust, more vulnerable to strong winds, and shorter-lived compared to enclosed garages. In contrast, Norsteel Carports are built with heavy-duty metal framing, using Rigid Frame systems to ensure they are structurally sound. Our carports are engineered as permanent, highly durable structures that require proper foundations and, in some cases, permits. As mentioned in this article, our steel carports without walls can cost as much as a garage because they need reinforced framing to handle uplift wind pressure from open sides.
Conclusion: Both Norsteel garages and carports are engineered to handle snow loads, wind, and time, delivering superior strength and durability, standing far above lighter framed carport options. Choosing between them comes down to whether you need a full enclosure or an open design with uncompromising structural performance.
Customization & Design Options
- Steel Garage: Fully customizable. Choose dimensions, door styles, windows, and colours. Add insulation, interior finishes, lofts, shelving, and more.
- Steel Carport: Basic design options with fewer features. It can be sized and coloured to fit your space, but lacks enclosure and layout flexibility.
Conclusion: A garage offers more opportunities for personalization and functional upgrades, becoming a true extension of your home or property.
Permits & Planning
- Steel garage: Usually requires a building permit and compliance with local zoning rules.
- Steel carport: May not, depending on its size and location — though this varies by region.
Conclusion: Always check with your local municipality to understand what is required before starting your project. Norsteel provides engineered drawings and support for permit approvals.
Construction Timelines
- Steel Garage: Requires a longer timeline due to additional structural components, but pre-engineered kits make installation efficient and DIY-friendly. Depending on the size, the build can be completed within a week.
- Steel Carport: Quick installation — often complete in one weekend. DIY-friendly.
Conclusion: A carport is faster to build, but a garage remains efficient with the right system.
Adding a Carport to a Garage
You can absolutely do both. Many property owners install a garage for secure storage or workspace and add a carport extension for extra covered parking or equipment shelter. Just make sure both structures are engineered to work together — especially for snow loads, water drainage, and roof connections.
Add a steel carport extension to your garage for:
- Extra vehicle coverage
- RV or trailer protection
- Outdoor workspaces
Conclusion: A combo build gives you the best of both worlds offering flexibility and is easy to plan from the start or add later.
