Even if you are traveling with only one person, you will not support all of your stuff in your trunk. So you have to find a better way to keep all of your property legally. And thankfully, there is a solution, and that is roof boxes.

So, let’s see what you should keep in mind if you want to buy a perfect roof box for you and what kind of roof boxes are perfect for your next big trip.

Beginner’s Guide Of Best Roof Boxes:

When you buy a roof box for your specific needs, you should keep the following points in your mind so that you can choose a perfect roof box for yourself.

1. The price:

The first and essential point while buying a roof box is the price. As much as you need a quality roof box, you don’t want to pay enough for it either; you also don’t want to go too expensive. After all, you’ll get what you are paying for.

The budget for an average but correct roof box is around 300$. If you want more facilities, you have to pay a couple of hundred dollars more. The size of a roof box is also a matter. Naturally, you have to pay more for the larger units.

2. Box Security:

The second important matter you should keep in mind before buying a roof box is its safety. No matter how much you are spending on a roof box. The box can easily be stolen from your car. So you have to find the roof boxes which is secured enough. And you should look for the boxes which can feature you with locks to keep your stuff safe.

That’s why you’ll want to pick a rigid roof box over a softer bag. The other options should be less expensive and can be used for shorter and less extensive road trips. But those are not as durable and don’t come with locks. 

The roof box’s hard body can protect your stuff from any external damage and protect them from potential thieves knifing your bags and stealing its content.

3. How well they secure in place:

Best Cargo Box

Now let’s see how well a roof box is safe when you are traveling with it. If you spend hundreds of dollars on a roof box, you’ll want to keep all of your stuff only in the box so that they could fly off the roof during the trip. When you choose a roof box, you have to pay attention to the roof box itself and how well the roof box suits into places.

Roof boxes can be secured in places in several ways. Among them, roof racks are the most common way to are ropes and ties.

How you will secure your roof box also depends on the size of your car’s roof. Most of the roof boxes are available as designed to match well with the roof of most cars. But it’s better to be sure that your car’s roof is suitable for the roof box you want.

If your car’s roof is small, you have to choose a small roof box to be secured properly. You have to avoid selecting those types of roof boxes which can expand over from the rear of your vehicle’s roof.

You should then think about how your roof box will prevent the weather’s torture in unfavorable conditions. You don’t want a strong flap of wind to blow the roof box from your vehicle’s roof, or to see heavy rain or snow cause it to come off from the top of your car, or anything else which have the same moisture can leak into your roof box and ruin your belongings.

That’s why top-ranking roof boxes feature bases that enhance the abrasion to keep the roof box perfectly in place. Moreover, if you plan for a drive in wet conditions, you’ll want to make sure to get a waterproof roof box.

4. Their Length and Width:

Best Cargo Box

Then you have to think about the size of your roof box. You can measure this by its length and width. But always remember that you have to make sure that your roof box is not larger than your vehicle’s roof.

Besides, you also have to make sure that the roof box wide enough to accommodate whatever you wish to pack in it. So you have to think correctly about what type of things you want to keep in the roof box.

Suppose you want to use them to bear something long and thin like a fishing rod, hockey sticks, skis, etc. Then you have to be sure that you are buying a roof box that is sufficiently big to keep your goods safe and can prevent them from snatching.

You have to think about the width also. If you plan to keep bags or similar items in your roof box, you have to make sure that you have enough space to keep them without squeezing or crushing. 

5. Roof Box Weigh:

You have to think about the weight also. All the roof boxes are not the same. Different kinds of roof boxes can tolerate a specific amount of weight. Moreover, different types of vehicles can bear different amounts of weight on their roof. If you want to carry your item without distorting or breaking them, then you have to ensure that you are taking the perfect roof box for you that can handle and carry your stuff excellently. Moreover, you should make sure about the roof box’s weight isn’t too much for your vehicle.

6. How it impacts on your vehicle’s mileage:

The size and weight of your roof box can also impact your vehicle’s mileage. The last thing you want is to think that you have enough gas only to find out you’ve enumerated without the added weight and drag of your roof box.

Nowadays, there are different kinds of roof boxes in the market, and obviously, many factors may be responsible for those differences. Therefore you have to be sure about your choice and confirm if the roof box you are going to buy is a gas mileage liability.

7. How Aerodynamic Roof Boxes Are:

Best Cargo Box

It is a matter that you should keep in thought because aerodynamic roof boxes can improve your gas mileage. If you want to increase your gas mileage a bit more, you have to choose a more aerodynamic roof box so that it can resist more air and help you get a little more gas mileage.

Thankfully, there is a wide variety of sleek roof boxes out there; they look so aesthetic. Besides, there is also a performance aspect to this.

You have to think about the performance and how costly they are. As a general rule, if the roof box is more aerodynamic, it would cost more because an aerodynamic roof box can help you cut down the gas mileage. If you are going on trips regularly, then buying an expensive roof box can worth it. 

On the contrary, bigger and heavier roof boxes may cost less. On the contrary, bigger and heavier roof boxes may cost less. But they are less aerodynamic and also responsible for more drag and strong gas mileage issues.

8. The Aesthetics:

Best Cargo Box

Let’s pause a moment for thinking about the shape of a roof box. If your roof box looks like a bulky and oversized freaky item, it can make your vehicle look ridiculous.

While we talked about aerodynamics above, we discussed how your roof box setup could significantly impact how well your vehicle can drive, including the roof box. A smoother build with a superb eye-catchy finish can make your car look much better when going on an open road.

The matter about your car’s look with a roof is entirely based on your emotion, but you have to think that are not you going on a trip to explore and feel the adventure of every bend? If a roof box can increase that feeling with its fascinating look, then isn’t that great?

So you’ll want to think about how your roof box looks on the roof of your vehicle. 

Roof boxes that are long but smooth are currently high on demand. These types of roof boxes are often round-shaped at the front and back. These types of roof boxes can resist more air. So they are famous because they are more aerodynamic. Again, roofs of clamshell can be opened upwards, which means that they can provide you with more space on the topside and these roof boxes are bigger than those longer and sleeker roof boxes.

Then you can also think about the color of your roof box. Indeed, this is an important matter. You can get currently famous roof box variants in different colors quickly. Besides, you can get them in glossy or matte finishes or whatever you want it to be.

9. Its Volume:

Best Cargo Box

You should think about the volume of a roof box also. It is a very important matter that you should keep in mind when you buy a roof box. You should search for a roof box with more volume and storage capacities than other roof boxes. You have to think about the size, weight, and aerodynamic-ness of your roof box also. But that is another matter. Still, the roof box that offers more space is almost always right.

How these roof boxes get the ability of more volume is another matter. Long slender boxes of similar sizes can offer you almost the same work and storage capabilities. The main thing is the size. Roof boxes of different sizes will always offer you different specifications and various volumes and some modifications.

You have to think correctly about which size of the roof box is right for you, including its volume.

10. Overall Compatibility:

Best Cargo Box

As we discussed before that, consistency is a must for the equation of a roof box. You have to be sure that your roof box is perfect for your vehicle’s roof. We also discussed how you are going to secure your roof box, but there’s something more than just being sure that it isn’t slipping down from the roof of your car.

Specific roof boxes are designed to fit well with specific vehicles. So you have to see carefully which classes of vehicles are suitable for the roof boxes we are going to mention here.

If your vehicle has previously installed racks on your car’s roof, you have to think about which type of roof boxes can cope with the roof rack. Various roof boxes are available for several types of roof racks. So you have to check that if the roof box you are going to buy can be installed with the existing roof rack. If that isn’t possible, you have to install the roof rack provided by the roof box.

If you do all the measurements correctly, you will perfectly attach the roof racks and the roof box that you will buy for your vehicle’s roof. If you want to install a high-quality roof box without any roof racks, that won’t be impossible for you, with ropes’ help, but that will be difficult, and it will look awkward and funny.

If you want to set your roof box without a roof rack, you must think carefully about the roof box’s configuration. Without any roof rack, you will find a few things to set your roof box on your vehicle’s roof correctly and prevent it from slipping down from your roof.

If your vehicle can cope with the roof rack provided by the roof box or with your existing one, then it will be better for you to use them for setting your roof box.

11. The way it opens:

Best Cargo Box

You can think that the way a roof box opens is a simple matter and not so important. But how a roof box opens and from which side you can open them is a very important matter.

Different Roof boxes can be opened from one or both sides. But with the roof box that can be opened from both sides, you can load and unload things faster from it by doing the loading or unloading from both sides together.

Moreover, if you have to park beside a wall then, you don’t have to be worried about how you are going to load or unload your stuff from your roof box because you will be able to open your roof box from both sides.

So you have to think about the opening direction of a roof box. Because roof boxes of clamshell can be opened upward, on the other hand, other roof boxes can be opened from the left side or right side or both sides.

12. Frequency of Use:

Finally, you have to remember how much you will use the roof box you will buy. The amount of use can have a great impact on the rest factors of the list. If you want to go on trips frequently, you should want to take a more costly roof box that offers you more facilities.

Again, if you go on trips infrequently, then a smaller and less costly roof box will be okay for you.


When you go to buy a roof box, you will see thousands of options before you. But you have to choose a roof box that is perfect for you. Whenever you go on any trip, you want to enjoy freedom. And you may know that space is all about choice, so you have to make a perfect decision about buying your roof box.
