How to Choose the Best Roof Box For Car
Choose between a hard shell box and foldable soft bags
The VonHaus Car Roof Box is a hard rooftop carrier featuring an aerodynamic shape, carbon fibre effect finish, and a central locking system. However, its 320L capacity is smaller than soft alternatives. If you need maximum volume, soft carriers like the Sailnovo 598L or BOYUJK Roof Bag offer up to 598L or 20 cubic feet of space, though they lack the rigid structure of a central-locking hard box.
Check vehicle compatibility and mounting options
Soft carriers cater to cars with or without existing roof racks. Options like the Zacro Car Roof Bag, Rymopuey Roof Bag, and GADLANE Car Roof Bag include 6 door hooks and anti-slip mats to fit bare roofs directly. For vehicles with crossbars or side rails, the Sailnovo 559L requires specific bar spacing between 41 and 45 inches, or a roof area of at least 51 by 39 inches when fitting to bare roofs.
Evaluate weatherproofing materials and extra security features
Material density varies across soft roof carriers. The GADLANE Car Roof Bag uses 900D fabric, while the Sailnovo 580L uses cold-resistant 1000D PVC with reflective covers and waterproof stickers. If extra security is a priority, the BOYUJK Roof Bag includes a combination lock and a 10cm zipper flap, whereas the VonHaus hard box relies on an integrated central lock.
Consider post-trip storage and packing flexibility
Rigid options like the VonHaus box occupy a fixed physical footprint in your garage when not in use. Soft alternatives like the Rymopuey Roof Bag and Sailnovo 580L fold down flat into compact drawstring storage bags. Soft bags also adapt better to awkwardly shaped camping gear, though you must avoid placing sharp objects inside the Sailnovo models to prevent punctures.
Buying Guide & FAQ
What is the best roof box for car deal right now?
Our current top-ranked deal is the Signstek 21 Cubic Feet Waterproof Car Roof Bag, Soft Roof Cargo Carrier for Most Cars, SUVs & Vans with or without Roof Rack at £47.89.
How much does a roof box for car cost?
Across our top 9 picks, prices currently range from £47.89 to £259.99 on Amazon UK.
What is the difference between a hard roof box and a soft roof bag?
A hard carrier like the VonHaus Car Roof Box features a rigid aerodynamic structure with central locking, protecting items inside a fixed 320L shell. Soft bags like the Sailnovo 598L or Zacro Car Roof Bag offer larger capacities up to 598L (20 cubic feet) and can be folded into a storage bag when empty, though they rely on straps and padlocks rather than integrated central locks.
Can I fit a roof box for car use without roof bars or rails?
Yes, several soft roof bags are designed to work on bare vehicle roofs. Models such as the Rymopuey Roof Bag, BOYUJK Roof Bag, and GADLANE Car Roof Bag include 6 door hooks and an anti-slip mat, allowing you to attach them safely through the car door seals without needing crossbars or side rails.
How do I secure my luggage inside a roof box for car travel?
Soft carriers rely on heavy-duty webbing straps and anti-slip mats to prevent movement. The Zacro Car Roof Bag and Rymopuey Roof Bag both provide 10 reinforced straps along with an anti-slip mat to protect the vehicle roof from scratches and keep luggage stable. For hard boxes like the VonHaus, items sit inside the rigid 320L enclosure secured by the central locking system.
Which roof box for car journeys provides the largest storage capacity?
The Sailnovo 598L Waterproof Car Roof Bag provides the largest volume listed at 598L. Other soft bags like the BOYUJK, Rymopuey, Zacro, and Sailnovo 580L models offer 20 cubic feet of capacity (around 550L to 580L), whereas the hard-shell VonHaus car roof box offers 320L.
How waterproof are soft car roof bags compared to hard boxes?
Hard boxes like the VonHaus are weather-resistant due to their solid shell design. Soft bags use sealed fabrics and zips; for instance, the Sailnovo models use triple-layer 1000D PVC with extended waterproof flaps, the GADLANE uses 900D waterproof fabric, and the BOYUJK features a widened 10cm zipper flap and double waterproof coating to keep moisture out.
How do soft car roof bags store away when not in use?
Unlike the VonHaus hard roof box which requires dedicated storage space in a garage or shed, soft models like the Rymopuey Roof Bag, Sailnovo 580L, and GADLANE fold down into compact drawstring bags that can be stored easily in a boot or cupboard.
