Buying Guide: How to Choose Your Roof Storage Box
What capacity do you need? Consider the typical cargo and how many people will ride with you. 17–18 cu ft options are common for families, while 20 cu ft may be ideal for max space during longer trips.
What type of access works best? Rear-opening, dual-side, or standard top access affects loading convenience. If you frequently load from the back, a rear-opening model can save time and reduce interference with the vehicle.
Is weatherproofing important? Look for hard-shell shells with waterproof seals. ABS plastic is common and durable, while some soft bags offer value but may not provide the same level of protection in heavy rain or snow.
Will your vehicle support a roof carrier? Check your roof rack type (crossbars, rails), weight limits, and clearance. Some models require specific crossbar spacing or mounting hardware for a secure fit.
Will you load from only one side or both sides? Dual-side loading models can reduce hassle in tight parking lots or when the rear area is constrained by tailgates or spoilers.
FAQ
- What’s the typical weight capacity for roof boxes? Most boxes range from 165 lbs to 200 lbs, but always verify the product’s specific rating and ensure it fits your roof rack’s max capacity.
- Do roof boxes fit all cars? They fit most cars with roof racks, but compatibility depends on crossbar type, spacing, and vehicle height. Measure clearance and check the manufacturer’s guidelines.
- Are rear-opening boxes safer for luggage? Rear-opening designs reduce the chance of hitting other vehicles or loading clips at the side, which can improve loading efficiency in busy areas.
- How do I maintain a roof box? Clean with mild soap and water, check seals for wear, and inspect mounting hardware for tightness before trips.
- Can I use a roof box without roof racks? Some soft-sides can mount to bare rails or cargo rails, but most hard-shell boxes require crossbars for stable installation.
- What should I consider for long trips? Choose a box with ample capacity, secure locking, weatherproof seals, and an aerodynamic shape to minimize wind drag and noise.
