Understanding Snow Load Ratings for Metal Carports
Snow load capacity refers to the maximum weight of snow a structure can safely support before risking structural damage. This is typically measured in pounds per square foot (psf). For example, a 30 psf snow load rating means the carport can support 30 pounds of snow on each square foot of its roof.
What many buyers don’t realize is that regional building codes establish minimum snow load requirements based on historical weather data. These requirements ensure structures can withstand typical winter conditions in your specific location. However, quality carport manufacturers like The Carport Co. routinely exceed these minimum requirements, providing an additional safety margin.
How Regional Snow Loads Impact Your Carport Needs
Snow load requirements vary dramatically across the country:
- Northern states and mountainous regions: May require snow load ratings of 40-100+ psf
- Mid-Atlantic and Midwest regions: Typically require 25-40 psf
- Southern states: Often require 10-20 psf, with some areas having minimal requirements
What’s particularly important to understand is that local building codes already include safety factors above what an area typically experiences. For instance, if historical data shows maximum snow accumulation might reach 18 psf in your area, local codes might require structures to withstand 23 psf. The Carport Co. takes this a step further by engineering carports to handle 30 psf or higher in such regions, providing exceptional peace of mind during heavy snowfall events.
Standard vs. Commercial Truss Carports for Snow Handling
When considering a carport for high snow load areas, the structural design becomes particularly important:
Standard Carports
- Can be engineered for snow loads up to 100 psf
- Feature reinforced framing and appropriate roof pitch
- Utilize heavier gauge steel in high-snow regions
- Include proper bracing to distribute snow weight
Commercial Truss-Style Carports
- Can handle even higher snow loads exceeding 100 psf
- Feature advanced truss engineering for superior strength
- Provide exceptional stability during heavy snow events
- Offer wider clear-span options without compromising snow load capacity
The key difference lies in the roof structure. Truss-style carports distribute weight more effectively across multiple support points, making them ideal for regions with extreme winter conditions or for customers seeking maximum protection.
Critical Design Features for Snow-Resistant Carports
Several design elements significantly impact a carport’s ability to handle snow loads:
Benefits of Metal Buildings in Today's Market
Despite price fluctuations, metal buildings continue to offer compelling advantages over traditional construction:
- Durability: Galvanized tube steel structures withstand severe weather, resist pests, and don’t rot or warp.
- Cost-Effectiveness: Even with market uncertainties, metal buildings typically cost less per square foot than traditional construction.
- Versatility: From simple carports to complex workshops or agricultural buildings, metal structures can be customized to meet virtually any need.
- Quick Installation: Prefabricated components mean faster completion compared to traditional building methods.
- Low Maintenance: Metal buildings require minimal upkeep, saving money over the lifetime of the structure.
1. Roof Style
Vertical roof carports substantially outperform horizontal and regular roof styles in snow conditions. The vertical panels allow snow to slide off rather than accumulate, reducing the effective load on the structure. This design feature alone can dramatically improve winter performance.
2. Frame Gauge
The thickness of the steel tubing used in your carport directly affects its strength. In high snow load areas, 12-gauge or 14-gauge framing provides significantly better support than the lighter 16-gauge alternatives some manufacturers use to reduce costs.
3. Roof Pitch
Steeper roof pitches shed snow more effectively. For areas with regular heavy snowfall, a minimum 3:12 pitch (the roof rises 3 inches for every 12 inches of horizontal distance) is recommended. Some designs can incorporate even steeper pitches for extreme snow regions.
4. Support Spacing
Properly engineered carports adjust the spacing between support columns based on expected snow loads. High snow areas require closer support spacing to distribute weight more effectively.
Determining the Right Snow Load Rating for Your Location
Making an informed decision about snow load requirements doesn’t have to be complicated. The Carport Co. has simplified this process through their Wind and Snow Load Tool, which helps customers determine the exact requirements for their specific location.
This tool considers:
- Your exact geographic location
- Local building code requirements
- Historical weather data for your area
- Recommended safety margins
By entering your address information, you’ll receive precise recommendations for the snow load rating your carport should meet or exceed. This eliminates guesswork and ensures you select a structure that will perform reliably year after year.
Real-World Performance of Metal Carports in Snow Conditions
Customer experiences provide valuable insights into how metal carports perform in actual winter conditions. Across northern states, properly engineered metal carports have demonstrated excellent performance even during record-breaking snowfall events.
For example, during the winter of 2021-2022, parts of the Northeast experienced snowfall that approached historical records. Properly engineered carports with appropriate snow load ratings showed minimal deflection (temporary bending under load) and returned to their original shape once the snow was removed or melted.
It’s worth noting that even the best-designed carports have practical limits. During extraordinary weather events, periodic snow removal may still be necessary, particularly if snow accumulation approaches the design limits of the structure.
Maintenance Tips for Carports in Snowy Regions
To maximize the winter performance of your metal carport:
- Inspect annually: Before winter, check all connections, fasteners, and structural components for any signs of wear or damage.
- Remove excessive snow: While quality carports can handle substantial snow loads, removing excessive accumulation during extreme events provides additional safety margin.
- Clear ice dams: Prevent ice from forming at roof edges, which can block proper drainage and create concentrated loads.
- Check for uneven loading: Snow drifts can create unbalanced loads on your carport. Pay particular attention to areas where snow might accumulate unevenly.
- Monitor for unusual deflection: Some temporary roof deflection under heavy snow is normal, but excessive or asymmetrical bending may indicate a problem requiring attention.
Investment Considerations for Snow-Ready Carports
Carports engineered for higher snow loads typically require additional materials and more robust engineering, which impacts pricing. However, this additional investment provides significant benefits:
- Extended structural lifespan
- Reduced maintenance requirements
- Lower risk of weather-related damage
- Greater peace of mind during severe weather
- Potential insurance advantages
- Higher resale value
When comparing quotes from different suppliers, pay careful attention to the snow load specifications. Lower-priced options may achieve their price advantage by using lighter materials or designs not appropriate for your local conditions.

How much snow can a carport hold?
Quality metal carports from The Carport Co. can be engineered to withstand snow loads from 30 psf up to 100+ psf, depending on the design and specifications. Standard models handle most regional requirements easily, while commercial truss-style carports can support even higher loads for extreme snow regions or commercial applications.
Will snow collapse my metal carport?
A properly engineered metal carport built to your area’s snow load requirements will not collapse under typical winter conditions. The Carport Co. structures are over-engineered beyond local building code requirements, providing additional safety margin. For example, if your area might experience maximum snow loads of 18 psf, and local code requires 23 psf capacity, our carports would be built to handle 30 psf or higher.
What roof style is best for snow on metal carports?
Vertical roof carports are significantly superior for snowy conditions. The vertical panel orientation allows snow to slide off rather than accumulate, dramatically reducing the effective load on the structure. For moderate to heavy snow areas, a vertical roof style should be considered essential.
Do I need to remove snow from my metal carport roof?
Under normal winter conditions, properly engineered carports from The Carport Co. don’t require snow removal. However, during exceptional storms that approach your structure’s design limits, removing excessive accumulation provides additional safety margin. This is particularly important if snow drifts create uneven loading.
How do I know what snow load rating I need for my carport?
The most reliable approach is using The Carport Co.’s Wind and Snow Load Tool, which provides personalized recommendations based on your exact location and local building codes. This eliminates guesswork and ensures your carport meets or exceeds all local requirements.
Are metal carports better than wooden carports for snow?
Yes, properly engineered metal carports typically outperform wooden structures in snow conditions for several reasons: they don’t absorb moisture, maintain consistent strength regardless of temperature, resist rot and insect damage, and can be precisely engineered to meet specific load requirements. Steel’s high strength-to-weight ratio also allows for designs that maximize snow load capacity while minimizing material usage.
Can I increase the snow load capacity of my existing carport?
While some retrofitting options exist, such as adding additional supports or reinforcing existing components, these approaches have limitations. For significant increases in snow load capacity, replacing the structure with one specifically engineered for higher loads is typically more cost-effective and reliable.
Do snow load requirements affect carport pricing?
Yes, carports engineered for higher snow loads require additional materials, heavier gauge steel, and more sophisticated engineering, which impacts pricing. However, this additional investment provides significant benefits in structural integrity, longevity, and peace of mind during winter conditions.
