Both these types of cargo carriers have their own pros and cons. So before making any purchase, you have to consider everything carefully.

Hard Roof Cargo Carriers

Hardshell roof cargo boxes are mostly famous because of their sturdy, durable build quality. Most roof boxes are 100% waterproof, and they also come with locking mechanisms. Roof boxes are designed to be more aerodynamic than roof cargo bags. So the design will not affect your fuel economy that much. 

You should also know that you might face problems in storing anything with a large or unusual shape because the sides, top, and bottom are all rigid. So if you want to carry anything like that, then you should buy a soft cargo bag.

Many soft-type roof bags do not require any roof rack to get installed. So you do not have to spend any money to buy a roof rack and install them on top of your car. You should know that not all roof bags are 100% waterproof. So you have to check the specification carefully if it is waterproof or not. Moreover, roof bags do not come with as many security features as roof cargo boxes.

Type of Vehicle

You also need to consider the type of your car; where you are going to install the cargo carrier is also important. Most cargo carriers sit on the roof of your car. So you have to consider many things, including how your vehicle opens and what is the weight carrying capacity of the roof of your car. 

It would be best if you bought smaller cargo boxes for a smaller car. If you do not do that, you will face many problems, like the cargo box will block the vision through the front windshield, and you might fall into an accident. 

Again if the cargo carrier is too much on the back, then you might not be able to open the trunk door of your car, especially if it is a hatchback. So you have to choose the right roof cargo box for your vehicle carefully. 

You will be happy to know that manufacturers have taken notice of this problem and now offer online tools to help buyers find a carrier that will fit their vehicle. 

But whatever you should consider other factors on this list when shopping so that you can choose the right one for you more easily.

Type of Roof Rack

You have to choose a roof rack that is compatible with the roof cargo box that you are willing to buy. Some cars are not compatible with a roof rack, but you can find a roof cargo carrier that does not require any roof rack to get installed on top of your car. You will be able to find a great quality roof cargo box with this type of feature but finding one can be a little hard.

The rest cars either come with a set of side rails or a full roof rack. Roof cargo boxes are easy to fit on those cars because the side rails and roof racks are specially designed to accommodate a cargo carrier. But whatever, you should always check if the cargo carrier is compatible with the roof rack you have. Otherwise, you might face problems while installing the cargo carrier on top of your car.

Type of Storage

How to Pack Roof Box

This is one of the most important things you have to consider while shopping for a roof cargo carrier. You have to buy a cargo carrier according to the cargo you need to carry. This is very important because if you want to carry skis, snowboards, or fishing rods, you will need to buy a long cargo box. so that you can carry your gear without damaging them. However, longer roof boxes are able to accommodate fishing rods without bending them. 

Again if you and your family only need a little bit of extra storage space, then you can consider buying a short roof cargo box because these roof boxes are very easy to install and remove. Again a short roof box will cost you less than a bigger one.

So always consider carefully before taking any decision.


Roof cargo boxes are available in different sizes. The smallest cargo carrier comes with around ten cubic feet of storage space, and the bigger cargo boxes are available with more than 20 cubic feet of storage space. If you have a smaller vehicle or a small family, then you should buy a small cargo box. But if you have a big family, you will need a big roof cargo box to carry all the items safely so that everyone can sit comfortably inside the car. 

Frequency of Use

It would be best if you also considered how often you are going to use the cargo carrier because it can affect your driving.

You have to consider whether you are going to leave your cargo carrier on your car for several years or you are planning to remove it after every single trip.

If you want to leave the carrier on top of your car, then you will not need to care whether the installation process is easy or a little hard. But if you want to remove the cargo carrier from the roof of your car, then you should find a cargo carrier that is easy to install and remove. 

Opening and Accessibility

It would be best if you considered how you would like to have access to the cargo box. There are many roof cargo boxes available on the market that can give you access to your belongings from both sides of the car. These are the most versatile cargo box. The rest can give you access from only one side. 

So it would be best if you considered what side of the road you will be on when you are opening your carrier before you make any purchase.

Some cargo boxes are very easy to open than others so that the users can easily access their items inside the cargo box.


You also need to consider the security of your items inside the cargo carrier. If you just leave your valuable stuff inside the cargo carrier without ensuring enough security, it might get damaged or get snatched from your roof box by the time you reach your destination.

So you should always find a roof cargo box that comes with an advanced locking system so that you can ensure the security of your items and drive peacefully. 

Weight Limit

Different roof cargo box comes with different weight carrying capacity. So you have to consider the amount of weight you want to carry with the cargo box. If you have a large family or you want to take a lot of heavy gear on your trip, then you should look for a cargo box with that much weight carrying capacity so that your cargo carrier does not get damaged.

If you keep a lot of items on the roof without ensuring proper safety, then they can be damaged, and those items may not be secure or safe. 


aerodynamic roof

If you install a roof cargo box on top of your car, it will affect the fuel economy of your car. So it would be best if you always chose an aerodynamic roof box because the design of these cargo boxes is able to lessen the drag so that these cargo boxes will affect your fuel economy less badly than a non-aerodynamic one. 

If you choose a cargo box that comes with a bulky shape, then it might provide you with a lot of storage space, but it will increase the drag, and you will need more fuel to reach your destination.


Choosing the right roof cargo box for you can be a little hard, but it is not impossible. Our choosing Car Cargo Carrier guide will help you to find the best option for you easily. While shopping you have to consider many things. If you do not do that, then you might regret it after buying.
