The Ultimate Buying Guide for Your Cargo Roof Box
A cargo roof box is a fantastic way to add extra storage space to your car. It sits right on your roof. This frees up room inside your vehicle for passengers and smaller items. Whether you are heading on a long road trip or just need more space for gear, a roof box is a great helper. But how do you choose the right one?
Key Features to Look For
When shopping for a roof box, a few important features stand out. These details make a big difference in how well the box works for you.
Capacity and Size
- Volume (Liters): Think about how much stuff you need to carry. Boxes come in many sizes, usually measured in liters. Small boxes hold a few bags. Large boxes can fit skis or camping equipment.
- Length and Width: Make sure the box fits your car’s roof racks without hanging over too much. Check your car’s manual for roof load limits.
Ease of Installation and Access
- Mounting System: Look for easy-to-use clamps or mounts. Some systems let you attach the box in minutes. Others take more time and tools.
- Opening Style: Most boxes open from one side. Premium boxes often open from both sides (dual-side opening). This makes loading and unloading much easier from either side of the car.
Security and Durability
- Locking Mechanism: A good box must have strong locks. This keeps your belongings safe from theft.
- Weatherproofing: You need a box that keeps rain and dust out. Check for strong seals around the edges.
Important Materials Used
The material of the box affects its strength, weight, and price.
Plastic Options
- ABS Plastic: This is very common. ABS is tough and resists dents well. It is usually lightweight too.
- Polypropylene: This material is often used for budget boxes. It is flexible but might not be as stiff as ABS.
Fiberglass (Less Common)
- Fiberglass boxes are very strong and aerodynamic. However, they cost more money and are heavier than plastic options.
Factors That Improve or Reduce Quality
Quality isn’t just about the material; it’s about the design.
Things That Boost Quality
- Aerodynamics: A sleek, curved shape cuts through the wind better. This reduces wind noise and might save a little on gas mileage.
- Stiffening Ribs: Boxes with internal supports (ribs) feel stronger. They stop the plastic from flexing too much when packed full.
- UV Protection: Good boxes have coatings that stop the sun from making the plastic brittle over time.
Things That Lower Quality
- Thin plastic walls are a sign of lower quality. These boxes can crack more easily under stress.
- Flimsy hinges and cheap plastic locks break quickly. Always test the latches before buying.
User Experience and Use Cases
Think about how you will actually use the box.
Road Trips
For long trips, you want a quiet box. Aerodynamic designs really help here. You will appreciate dual-side opening when you stop at rest areas.
Sports and Hobbies
If you carry long items like fishing rods or skis, measure the interior length carefully. Make sure the box opens wide enough for your gear.
Daily Driving
If you keep the box on your car all the time, choose a lighter model. Heavy boxes use up some of your car’s weight capacity even when empty.
Frequently Asked Questions (FAQ) About Cargo Roof Boxes
Q: Do roof boxes hurt my gas mileage?
A: Yes, they create drag, which means your car uses more gas. A smooth, aerodynamic box hurts mileage less than a bulky, square one.
Q: Can I wash my roof box?
A: Absolutely. Most plastic boxes can be washed with mild soap and water, just like the rest of your car.
Q: Are roof boxes waterproof?
A: High-quality boxes are very water-resistant. They keep out normal rain. However, driving through a very heavy storm might let a tiny bit of moisture in near the seals.
Q: How much weight can a roof box hold?
A: This depends on the box itself and your car’s roof rack system. Check both manuals. Most boxes hold between 100 and 165 pounds.
Q: Do I need special roof racks?
A: Yes. You must have crossbars (the bars that go across your roof) installed first. The box then attaches securely to these crossbars.
Q: How loud are roof boxes on the highway?
A: Noise levels vary greatly. Boxes with wind tunnels or spoilers built into the design are quieter. Cheap, square boxes often whistle or roar at highway speeds.
Q: Can I still open my trunk or hatchback?
A: Usually, yes. However, if you get a very long box, it might block the full opening of your rear hatch. Measure the box length against your car’s rear door swing.
Q: What is the difference between a roof bag and a roof box?
A: A roof bag is made of soft fabric, similar to a giant duffel bag. A roof box is hard plastic or fiberglass, offering much better protection from weather and theft.
Q: Are roof boxes hard to install?
A: Modern boxes are designed for quick installation, often taking 15 to 30 minutes once you learn the system. Look for “tool-free” mounting if you plan to take it on and off often.
Q: Should I get a top-loading or side-loading box?
A: Top-loading is standard. Side-loading (dual-opening) is much more convenient for grabbing items in the middle without unloading everything else.
