Rooftop Cargo Boxes

Filter By:
Rooftop cargo boxes are a premium solution for expanding your vehicle’s storage capacity, providing a secure and weather-resistant way to transport bulky or oversized items. These hard-shell boxes mount to the roof of your car, SUV, or truck, offering additional storage space without sacrificing interior comfort. Designed with aerodynamics in mind, rooftop cargo boxes minimize wind drag and noise, ensuring a smooth, efficient ride while keeping your gear safe and secure. They are perfect for long trips, road adventures, or outdoor activities like camping, skiing, and biking, allowing you to bring along extra luggage, sporting equipment, or gear that wouldn’t otherwise fit inside your vehicle.


Available in various sizes and designs, rooftop cargo boxes feature lockable latches and easy-to-use opening mechanisms for both safety and convenience. Many models are designed to open from either side, providing quick and accessible loading and unloading. These boxes are made from durable materials such as high-density polyethylene or ABS plastic, ensuring strength and protection from the elements. Whether you need to free up space in the vehicle’s cabin or need extra storage for a family vacation or outdoor excursion, rooftop cargo boxes offer a reliable, durable, and stylish solution for carrying gear securely on the road.

Frequently Asked Questions

A rooftop cargo box is a highly versatile cargo carrier that mounts to the roof of most vehicles, including SUVs, minivans, sedans, and some smaller cars. They mount and stay secured to your vehicle via crossbars on top of the roof.

When comparing roof boxes vs. cargo racks, what are the benefits of roof boxes?

They’re Aerodynamic:

When adding heavy or bulky loads to the top of your roof, your vehicle becomes prone to experiencing some drag. Luckily, most hard-shell rooftop boxes feature an aerodynamic design that reduces drag. The result of having less drag is better fuel efficiency, which is a big money-saving plus.

Quiet Ride:

Another perk of reduced drag is reduced wind noise by proxy. This mitigates any shaking or rattling sounds. The result is a more peaceful, enjoyable ride.  

Superior Security:

There are plenty of high-quality roof boxes that come equipped with a built-in locking mechanism for optimal security. The presence of a lock will deter sly passersby looking to “borrow” your gear. You can also secure your roof box to help quell any unwanted effects of wind, mischievous animals, or other outdoor variables.

Easy Installation:

The best roof boxes are made to have very straightforward installation processes. They easily attach to your vehicle’s roof bars in just a few minutes.

Where do roof boxes fall short in the race between roof boxes vs. cargo racks?

They Can Cost a Pretty Penny:

Due to their high-quality materials, prestigious engineering, and long-lasting durability, roof boxes can be a big upfront investment. However, they generally last a long time and perform well, making them worth the pretty penny.

Can’t Accommodate All Cargo:

Roof boxes can’t be good at carrying everything. By nature, they’re not designed to carry bikes, skis, snowboards, or other lengthier types of cargo. You’d need an actual ski roof rack, bike rack, or hitch rack for longer, bulkier items.

Can Affect Vehicle Aerodynamics:

The wrong roof box can negatively impact aerodynamics. This is especially true if you get one that is poorly made or too large for the dimensions of your vehicle. If you decide to get a roof box, be sure to opt for a high-quality aerodynamic one, well fitted to your vehicle.

Hard to Fit on Vehicles:

Roof boxes can be a challenge to fit onto some vehicles, so it’s definitely important to take proper measurements of your vehicle’s roof before buying yours to ensure compatibility. Having crossbars and a roof box that are compatible will help streamline the process.

To determine what the best roof box for your vehicle is, first measure the dimensions of your vehicle’s roof. This will determine what size roof box you could realistically fit there. Also, take into account your personal storage needs. What do you intend to fit in your cargo box? Is it a full-size tent and camping gear? Or is it a couple of small suitcases? Bigger cargo will require a bigger box.
