Roof Rack

If you want to install a cargo box on top of your car, that will require a roof rack. A roof cargo box is compatible with a particular type of roof rack. So if you already have a roof rack installed on top of your car that might not be compatible with the cargo box, you are willing to buy.

Security

In terms of security, a roof cargo box works great than a roof cargo bag. Most cargo boxes come with a locking system. Again there is the scope of adding an extra lock if you want to. Moreover, cargo boxes have a hard shell design.

In contrast, a roof cargo bag comes with a soft fabric construction that can be slit open with a knife. And there is no locking mechanism included. So if security is a concern for you, then you should choose a roof cargo box.

Storage

You have to consider what you will do when the cargo carrier is not in use. With a roof cargo bag, it is very easy to store when not in use. You can easily fold it in any shape you want and keep it in a safe little place.

But with a cargo box, you will not be able to do this. You will need to find a place where you can keep this cargo box. If you have a garage, that can be a good place to store your roof box, but that can be a real problem if you do not have any.

Again if you do not want to remove the cargo box from the roof of your car, then you have to remain careful about the height of your car while you are going to drive under a low bridge.

Cost

After all, if you are willing to spend a good amount of money on a cargo carrier, then you should go for a roof cargo box. But if you have a limited budget, then you can buy a roof bag.

There are many rood boxes available at a lower price that are comparable to the price of a cargo bag. Again there are many expensive cargo bags as well that are comparable to the price of cargo boxes.

Which One is Better?

To find the better option you should consider the following things. 

  • amount of Storage space
  • Compatibility with vehicle
  • Security
  • How you will store it after use 
  • Cost

Suppose you are not going to carry anything valuable to you. In that case, you should buy a cargo bag because it will save you a good amount of money while providing you with enough storage space, protection from any kind of extreme weather condition.

But if you want something that can carry your valuable items full of safety and you are willing to spend a good amount of money after it, then you should buy a roof cargo box. Because cargo boxes are more durable and they are weatherproof as well. They come with a lot of storage space, and they will keep all of your items safe.
