Which is the best roof box?

Getting the best car roof box is down to personal preference. Considering the following factors and different brands will help you to choose the best roof box for your needs.


If you're a lone ranger who loves getting lost in the countryside, then a small, lower-capacity roof box may do the job for you. If you're going away with the family for two weeks, then you’ll probably want to go for the biggest size you can find.

Another consideration is whether you’re going to be taking any other sports equipment with you, like bikes. If so, you might want to consider a half-sized roof box so that you can fit a roof-mounted bike rack on the other side of your roof bars.

Build materials

What the roof box is made of will affect its performance. Cheaper roof boxes made from thinner plastic may vibrate in the wind, creating extra noise, or may not last as long as sturdier roof boxes made from tougher plastics. Simply put, the more you pay, the more durable the materials. All of our roof boxes are made from strong, scratch-resistant ABS materials that are UV-protected, preventing cracking or brittleness over time.

Type of fitting

As roof boxes use a variety of fittings, it's worth checking that they're compatible with your roof rack system and that they'll make life easier for you. If you don't fancy standing in the rain trying to take your roof box off after a tiring weekend of camping, consider quick-release fasteners like the power click mount in our Halfords Advanced and Thule roof boxes.

Type of opening 

The way your roof box opens is important, especially if you want easy access to items that may be obstructed by other luggage. For example, with a side-opening roof box, you'll only be able to load from one side, whereas a dual-opening or hinged roof box will allow you to access the contents from either side of the vehicle.
