Can You Put a Cargo Bag On a Sunroof
Drivers with sunroofs often still need extra cargo space for road trips and movable storage. But the sunroof limits roof rack options. Is there a way to safely add a cargo bag or carrier when you have an open sunroof? This comprehensive guide examines cargo carrier compatibility, risks, secure mounting methods, and expert recommendations for transporting gear on a vehicle with a sunroof.
The Short Answer
You can place certain cargo carriers on a sunroof as long as ample open space remains, weight limits are observed, and the bag or box is securely mounted to sturdy roof rails or crossbars without resting on the glass itself. Soft-sided cargo bags are the best sunroof-friendly option.

Challenges of a Sunroof for Roof Storage
Sunroofs present a few compatibility issues for roof storage:
- Take up roof real estate needed for mounts and bases
- Don’t provide a solid surface to rest cargo on
- Have weight limits less than the roof itself
- Can be easily damaged if cargo shifts
But with careful selection of carrier type, size, and mounting method, you can safely add gear storage that works with your sunroof.
Cargo Carrier Options for Sunroof Vehicles
Here are roof carrier options that work for sunroof vehicles and key considerations for each:
Cargo Bags
- Soft sides mold around sunroof
- Attach to crossbars with straps
- Ensure no direct contact with sunroof
Small Roof Boxes
- Compact to fit around sunroof opening
- Securely mount only to rails/crossbars
- Avoid models that require roof contact
Hitch Racks
- Provide rear cargo space
- Work with all roof types
- Limitaions on cargo size and type
Measure sunroof size and use carriers small enough to allow ample open space around the opening.

Proper Mounting Techniques
Mounting cargo properly is critical on a sunroof vehicle. Follow these guidelines:
- Only attach to factory roof rails or crossbars
- Never let carriers rest directly on the sunroof panel
- Distribute weight evenly between mounts
- Securely tighten all clamps and straps
- Load within recommended weight limits
- Check mounting stability before driving
Improper mounting can damage your sunroof, lead to a dangerous load shift, or even detach your cargo carrier at speed. Take time to mount every contact point securely.
Weight Considerations and Limits
When adding cargo to a sunroof vehicle, pay close attention to weight:
- Check sunroof weight limit (often 100-150 lbs)
- Consider total load on the roof, including crossbars/rails
- Use a lightweight carrier and low-density cargo
- Scale your load and aim for 75% of limits
- Load heavier items below cargo, not up top
Exceeding weight maximums risks sunroof damage or compromised handling and braking. Erring under capacity helps ensure secure stability.
Tips for Loading and Driving with Sunroof Cargo
Once mounted, keep these tips in mind:
- Load cargo evenly side-to-side
- Secure contents tightly and lock zippers/lids
- Avoid sudden acceleration and braking motions
- Take slower turns and corners
- Allow added stopping distance
- Check mounting stability at fuel stops
- Lower your speed to reduce wind force
Careful packing, driving, and re-checking during transit will keep your cargo stable and minimize sunroof strain.
Key Takeaways for Carrying Cargo with a Sunroof
- Cargo bags are the most sunroof-friendly carrier option
- Mount only to roof rails or crossbars, not the sunroof itself
- Mind sunroof and cargo weight limits
- Distribute load evenly and secure contents
- Drive cautiously and check mounts regularly
With smart carrier selection and proper mounting techniques, you can safely add extra cargo capacity to your sunroof car. Just take precautions during loading, travel, and parking to avoid overloading or shifting forces on your sunroof.
