Things To Consider When Buying A Roof Box

A lot of different factors influence the kind of roof box you should buy. Here are a few considerations to keep in mind while making your choice to help you choose the best roof box.


The first essential step in finding your ideal roof box is determining the maximum length of the carrier that your vehicle can fit. The box should not be so long that it reaches over your windshields on either side. It may affect your ability to see the road.

The size may also influence aerodynamics. Ensure that the back of your box does not obstruct your rear hatch opening or antenna. You should measure the distance between the front crossbar of your roof rack and your open hatch to find the perfect length of a cargo box for your car. It should be wide enough for the items of your choice without cramming or crushing anything in terms of width.


The shape of the box has a significant impact on the aerodynamics of the car. People generally prefer more aerodynamic models as they reduce wind noise. These products also maximize the mileage on your outings.

Taller rooftop boxes end up creating drag. If you are planning longer trips, a sleeker model would be better suited. The shape also influences how visually appealing the box is.


Your cargo box would be able to fit in whatever you’d like to carry without snapping it to pieces. You should first assess the items that you plan on storing in these rooftop boxes. Based on those items, select a box that can accommodate them without much hassle. 

More voluminous boxes are generally preferred over smaller ones. Boxes with a volume of 16 to 18 cubic feet should be enough to hold camping gear for up to four people.


Security is one of the most important aspects to look for in the best roof box. A cargo box is not of much use if it fails to keep your belongings safe. The box should come with at least one lock and key.

Most of the rooftop cargo boxes don’t let you remove the key unless the box is locked. While some people may argue that it is bothersome, it keeps your belongings safe by ensuring that you never leave the cargo box unlocked.

The opening and closing mechanism of the box can also influence your choice. Some high-end products come with locking mechanisms that include push buttons, twist handles, or even sliders.

Some models also combine the open and close mechanism to the lock system. The lock system then becomes responsible for securing the lid of the box to its base. Moreover, a few boxes even come with an indicator to know that they have been secured.


There are three main styles of rooftop cargo boxes – one-side, dual-sided, and rear access. Dual-sided access boxes are pretty user-friendly. They allow you to open the box from both the driver’s side and the passenger’s side, but not at the same time.

In less expensive models, you are most likely to find one-sided or rear access. These boxes make it slightly less convenient to reach and organize your cargo.


Cargo boxes are installed on the roof of your vehicle. They encounter many harmful elements that they cannot avoid while on the open road. You should invest in a durable roof box that can withstand different conditions.

ABS is one of the most commonly used materials for creating roof boxes. It holds well against rigorous opening and closing of the box. It is also pretty lightweight. However, you should ensure that the lid of your cargo box is not very floppy.

Flimsy lids could mean that the lid and the base will not line up easily. You will have to extra careful while securing the box. Additionally, the hinges, handles, and locks should also be of good quality. If any of them break, they might leave your roof box unusable.

Assembly & Installation

Some cargo rooftop boxes are pre-built and ready to mount, while some require in-depth assembly. However, assembly is just a one-time thing, so it should not be your top priority while selecting the best roof box for your car.

In contrast, mounting is a process that you may frequently be performing. High-end models are usually more user-friendly, with clamps that slide on the tracks, tightened with the help of a thumbwheel, and are secured with a click sound using an integrated lever.

On the other hand, budget boxes generally come with simple U-bolt mounts that may require you to work with many tiny parts and put in a lot of effort. It can be an inconvenience if you take your box on and off often.


The interiors of cargo boxes are usually just huge compartments for storing your belongings. They may also include a pull strap to help you close the lid if it is out of reach.

Expensive models tend to house more features. Many boxes come with a removable felt-lined base to protect your cargo. Moreover, some roof boxes include motion-sensing LED lights or white-colored lids for improved visibility.


It would be best if you started browsing for products with a budget in mind. Different roof boxes are available at various price points. As you go up the ladder, you will find fancier products with more additional features and sleek designs.

However, cheaper products can also be quite durable. You should look for a product that falls in your price range and has the features you desire.


All this information on finding the best roof box may be overwhelming. Let us look at some of the most frequently asked questions about rooftop cargo boxes.

Does a roof box affect insurance?

Maybe. Whether significant or not, all modifications are considered important from the point of view of a car insurance company. Therefore, you should always let your insurer know about any modifications you make to your vehicle, including roof boxes.

An even better idea would be to inform your insurance company even before you actually purchase a rooftop cargo box. If you buy a roof box without consulting the insurance experts, you may end up wasting a significant amount of money, as the companies do not cover all kinds of roof boxes.

Notifying the insurance company also allows you to find out if there is another type of roof box that they recommend and cover. It is better to purchase a cargo box after speaking with the insurers to buy a box that you are assured is covered in your policy.

All modifications should be appropriately documented for them to be legally valid. Even if you make modifications to the roof box, you have to inform the insurance company. The company should provide you with new declarations which validate your modifications.

This entire process of informing and documenting modifications is necessary because if something goes wrong later on. The insurance company can deny the claim on the grounds that they did not know about it beforehand.

Once the modification is documented in black and white, you would have fulfilled your responsibility. You will be fully covered in such a scenario if the modification causes any harm or injuries to anyone.

Informing the insurance company is simply a way to protect yourself. If the company denies your claim, the documentation will give you a legal leg to stand on.

Does a roof rack increase fuel consumption?

Once you install a roof rack, a roof box, or even a rooftop bag, you will notice a difference in your mileage oil. Adding any extra weight to your vehicle will cause it to drag more, and fuel consumption is directly affected by drag.

The weight of the roof rack can lead to increased fuel consumption. Moreover, airflow also affects consumption. Adding a box on the roof of the car does not let air flow well over the top of the vehicle, worsening your gas mileage.

The size and design of the roof rack will also affect the amount of extra fuel being used. It means that an empty carrier and a carrier filled with cargo will affect your fuel consumption differently.

While you cannot completely eliminate the effect of rooftop racks on fuel economy, you can improve it. For starters, drive about five miles below the limit. The reduced speed caused the drag to reduce as well, improving your gas mileage.

Aerodynamically designed rooftop carriers are also a great way to improve fuel economy. The more aerodynamic the design of your roof box is, the less it affects your mileage.

Can you use a carwash with roof bars?

No, it is not recommended to take your car through an automatic car wash with a roof rack on top. Many parts of the rack can get caught in the car wash. The process could cause damage to both the roof rack and the car washing equipment.

Some places may even insist that you remove the roof rack before putting your car through the automatic wash. Tunnel washes are the worst option for a roof rack. When your vehicle is in the wash, it is pulled through the tunnel and attacked by huge brushes with soap and water. 

Roof racks have many tiny nooks and corners where the brush fibers can easily get caught. Furthermore, if the brushes get stuck to the roof rack, they may try to tip themselves free and end up breaking the car washing equipment or damaging your roof rack.

A hand wash is the best option for roof racks. They even protect the finish of your car by avoiding water pooling leading to rust. Here’s how you can check for rust in your car!
