If you’ve ever gone on a family trip, camping adventure, or long road journey, you’ll know how quickly car space fills up. Suitcases, tents, sleeping bags, and sports gear can take over the back seats, leaving passengers cramped and uncomfortable. This is where a roof box comes to the rescue.
A roof box is a practical storage solution that mounts onto the roof bars of your car, providing extra luggage capacity. It’s an excellent way to expand space, stay organized, and travel in comfort. In this guide, we’ll explore what a roof box is, why you should consider one, types available, installation tips, safety advice, and how to choose the right one for your needs.
What Is a Roof Box?
A roof box is a hard-shell, weather-resistant container designed to be mounted on the roof of a car. It opens from the side or both sides and securely stores luggage, camping gear, ski equipment, or bulky items that don’t fit inside the vehicle. Roof boxes come in different sizes, shapes, and weight capacities, catering to various vehicles and travel needs.
Unlike soft roof bags, a roof box offers superior durability, better protection against the elements, and added security with lockable lids.
Benefits of Using a Roof Box
There are several reasons why travelers invest in roof boxes:
1. Extra Storage Space
The most obvious benefit is the increased luggage capacity. Depending on the model, a roof box can add 300 to 600 liters of extra storage — enough to store 4–6 suitcases or sports gear.
2. Comfortable Travel
By relocating bags to the roof, passengers get more legroom and comfort during long drives.
3. Versatility
A roof box can carry almost anything — camping gear, golf clubs, fishing equipment, baby strollers, or even skis and snowboards.
4. Weather Protection
High-quality roof boxes are designed to resist rain, snow, dust, and sun damage, keeping your belongings safe.
5. Security
Most roof boxes come with built-in locks, offering peace of mind when leaving the car parked.
Types of Roof Boxes
Not all roof boxes are the same. Here are the main categories:
1. Small Roof Boxes
Perfect for city cars or when you only need a little extra space. These usually hold up to 300 liters.
2. Medium Roof Boxes
Ideal for family cars, medium roof boxes provide 400–500 liters of storage space, balancing size and aerodynamics.
3. Large Roof Boxes
If you have a big family or lots of gear, a large box with 500–600+ liters capacity is the best choice. Great for skiing trips or long vacations.
4. Sport-Specific Roof Boxes
These are long and narrow, designed to carry skis, snowboards, or fishing rods.
How to Choose the Right Roof Box
When buying a roof box, consider the following:
1. Car Size and Roof Bars
Check your car’s roof load limit and ensure you have roof bars installed. The box should fit without overhanging excessively.
2. Storage Capacity
Estimate how much space you need. If you’re a solo traveler, a small box may be enough, but for families, go for medium or large sizes.
3. Shape and Aerodynamics
Aerodynamic roof boxes are slimmer and reduce wind resistance, which saves fuel and minimizes road noise.
4. Opening Mechanism
Some boxes open from one side only, while others are dual-sided for convenience.
5. Security Features
Choose a box with a reliable locking system to protect your belongings.
6. Budget
Prices vary widely. While budget-friendly options exist, investing in a high-quality roof box ensures durability and safety.
How to Install a Roof Box
Installing a roof box is straightforward:
- Install Roof Bars – Make sure your car has compatible roof bars.
- Position the Box – Place the roof box evenly in the center of the bars.
- Secure Clamps or U-Bolts – Most roof boxes use clamps or U-bolts to attach firmly.
- Lock the Box – Ensure all fastenings are tight and the box is locked before driving.
Always double-check the installation before starting your journey.
Safety Tips for Using a Roof Box
While a roof box is highly practical, safe use is crucial:
- Stay Within Weight Limits – Check both the roof box’s capacity and your vehicle’s roof load rating.
- Distribute Weight Evenly – Avoid putting all heavy items on one side.
- Pack Light Items Inside the Car – Store heavier objects in the car’s trunk and lighter items in the roof box.
- Drive Carefully – A roof box changes your car’s aerodynamics, so take corners gently and watch your speed.
- Check Clearance – Remember that your car will be taller, so be cautious with parking garages and drive-throughs.
Popular Roof Box Brands
Some leading roof box manufacturers include:
- Thule – Known for premium quality, aerodynamics, and durability.
- Yakima – Offers versatile designs and secure locking systems.
- SportRack – Affordable options for budget-conscious buyers.
- Halfords – Popular in the UK for a wide range of roof boxes.
Roof Box Maintenance Tips
To extend the lifespan of your roof box:
- Clean After Every Trip – Wash with mild soap and water to remove dirt and salt.
- Lubricate Locks – Keep the locking mechanism smooth.
- Store Properly – When not in use, keep it indoors or covered to protect against UV damage.
- Check for Cracks – Inspect regularly for signs of wear and tear.
Roof Box vs. Roof Bag: Which Is Better?
Some travelers debate between a roof box and a soft roof bag. While roof bags are cheaper and easier to store, roof boxes are more durable, secure, and weather-resistant. If you travel often, investing in a roof box is worth it.
Final Thoughts
A roof box is more than just a storage container — it’s a travel game-changer. Whether you’re going on a weekend camping trip, a family vacation, or a ski adventure, having extra space on top of your car makes every journey more comfortable and organized.
