What Are the Considerations for Installing a Roof-Mounted Cargo Box for Additional Storage?

When preparing for a trip, every inch of storage space in your vehicle becomes valuable. However, car interiors can quickly become cluttered with gear, diminishing the comfort of the ride. As a solution, many people turn to roof-mounted cargo boxes. These rooftop compartments provide additional storage, taking some of the load off your vehicle’s interior. However, before you rush off to buy and install a cargo box, there are various aspects you need to consider. This article will guide you through these considerations, ensuring the cargo box you install meets your needs and is safe for use.

Choosing the Right Cargo Box for Your Vehicle

It’s not one-size-fits-all when it comes to roof-mounted cargo boxes. Different vehicles will require different types of boxes. The first thing to look at is the weight capacity of your vehicle’s roof. You can find this information in the owner’s manual of your car. Furthermore, you’ll want to check the dimensions of your rooftop, as you’ll need to ensure the cargo box will fit.

When choosing a box, you’ll want to consider the type of items you’ll frequently be transporting. For instance, if you’re an avid skier, you might want to invest in a longer box that could accommodate skis. Brands like Yakima and Thule offer a variety of box sizes and shapes to cater to different needs.

Considering the Weight of the Cargo Box and Its Contents

Once you’ve selected a suitable cargo box, the next step is to consider the weight of the box and its contents. The weight of your cargo box, plus the weight of your gear, should not exceed the roof weight capacity of your vehicle. Overloading your roof can impact the stability of your car, making it potentially hazardous to drive.

When packing your cargo box, it’s advisable to distribute the weight evenly. Uneven weight distribution can cause the vehicle to sway, which could lead to difficulty steering or even rollovers. It’s also important to secure all items in the box to prevent them from moving around while on the road.

Installation and Mounting of the Roof-Mounted Cargo Box

After choosing a cargo box and considering its weight, it’s time to install it. Most roof-mounted cargo boxes will require a roof rack as a base for installation. Check if your vehicle already has a built-in roof rack. If not, you will need to purchase one.

During installation, ensure that the cargo box is aligned in the center of your roof rack. This helps distribute the weight evenly across the roof of your vehicle. It’s also crucial to secure the box properly to the rack to prevent it from slipping or moving while you’re driving. Regularly check the box and roof rack to ensure all fittings and attachments remain secure.

The Impact on Vehicle Performance and Fuel Efficiency

A roof-mounted cargo box will inevitably alter the aerodynamics of your vehicle. This can impact your vehicle’s performance, particularly at high speeds. Therefore, it’s important to drive carefully, especially on highways.

The added weight and changed aerodynamics can also affect fuel efficiency. While this might not be a significant concern for short trips, it could add up for longer journeys. Some brands, such as Yakima and Thule, design their cargo boxes to be aerodynamic, thereby minimizing the impact on fuel consumption.

Maintaining Your Roof-Mounted Cargo Box

Like any other part of your vehicle, a roof-mounted cargo box requires maintenance. Regularly check the box for any signs of wear and tear. Address any issues promptly to prevent any potential damage to the box or your vehicle.

You should also clean the box regularly to prevent the buildup of dirt and grime. This is particularly important if you’ve been driving in areas with a lot of dust or dirt. Remember to secure the box properly to your rack after each cleaning.

Before each use, check that the lock on your cargo box works correctly. A faulty lock could result in the box opening while driving, causing your items to fall out. Regularly lubing the lock will keep it in good working condition.

While a roof-mounted cargo box can significantly increase the storage space of your vehicle, it’s essential to take the time to choose, install, and maintain it properly. This consideration will ensure that you can enjoy the convenience your cargo box offers safely and efficiently. Remember to always check the specifications of your vehicle and the cargo box, and ensure you do not overload your roof or the box. Regular maintenance and checks should be a routine part of using a roof-mounted cargo box.

Effects of Weather Conditions on Your Roof-Mounted Cargo Box

The impact of weather conditions on your roof-mounted cargo box is a crucial factor to consider. From extreme heat to heavy snowfalls, different weather conditions can affect the performance and longevity of your cargo box.

Heat can cause some materials to expand, potentially leading to warping or other damages. Therefore, if you live in or will be traveling to a hot climate, you might want to consider purchasing a cargo box made of heat-resistant materials. Yakima Skybox and Thule Motion are known for their durable materials that can withstand various weather conditions.

On the other hand, in colder climates with heavy snowfall, the weight of accumulated snow on your cargo box can exceed your vehicle roof’s weight capacity. It’s essential to regularly clear snow off your box to prevent overloading.

Rain and other precipitations can also seep into your cargo box if it’s not entirely sealed. Ensure the cargo box you choose is water-resistant or waterproof to protect your items from getting wet.

Lastly, wind can add substantial resistance, especially when you’re driving at high speeds. Notably, windy conditions combined with a high-speed drive can lead to instability. Choosing an aerodynamic cargo box can help mitigate this issue.

Long-term Storage and Removal of Your Roof-Mounted Cargo Box

Sometimes, depending on your needs, you might want to remove the cargo box from your vehicle roof. It’s crucial to remember that removing and reinstalling the cargo box should be done carefully to prevent damage.

Always refer to the manufacturer’s guidelines for the removal process. Typically, it involves unlocking and detaching the box from the roof rack. Make sure to safely store all the hardware and accessories to avoid losing them.

When it comes to long-term storage of your cargo box, keep it in a cool and dry place. Cover it with a breathable cloth to protect it from dust and insects. Regularly clean and inspect your box even during periods of non-use to ensure it’s always ready for your next trip.

If you’re unsure about the removal or reinstallation process, consult with a professional or the manufacturer’s customer service.


A roof-mounted cargo box is a great way to increase your vehicle’s storage space, particularly for long trips and outdoor adventures. While it does come with increased responsibility and considerations, the convenience and additional space it provides make it a worthwhile investment.

It’s essential to choose a cargo box that fits your vehicle roof, meets your capacity needs, and withstands weather conditions. Remember to install it correctly, distribute the weight evenly, and regularly maintain it, including during periods of non-use.

By making these considerations, you can enjoy the added storage that a roof-mounted cargo box provides, while ensuring the safety and efficiency of your vehicle. As always, refer to manufacturer guidelines and consult professionals if you have any concerns. Happy travels!
