Roof carrying guides

Practical UK guides to roof boxes, bars, fit, roof loads, journeys, sports carriers, storage, replacement parts and ownership.

Travel bags measured and laid out beside an estate car

The short answer

Start with the car and approved rack, then choose around the actual luggage. These guides take you through the measurements, access decisions and ownership checks that make a carrying setup useful.

Compare the shortlist →Check roof load

Choose the shape and capacity

Use the roof-box category for an overview and the main box comparison for three contrasting starting points. Then follow the detailed guide for the question you need to settle.

Confirm the carrying system

Check roof bars for the exact car, then use fit and roof load for clearance and the luggage-allowance calculator. A box that holds the bags still needs an approved rack and a suitable overall load.

Plan sports equipment and storage

For bikes, kayaks and winter kit, start with sports carriers. Before ordering a long shell, plan off-car storage and accessories around the space, support and handling you have at home.

Roof bars, mounting and compatibility

Check the exact vehicle and rack, then work through attachment, spacing and clearance. For an existing system, compare reuse, used-part inspections, factory bars, gutter feet and correctly matched replacements.

Loading, driving and travelling

Use the worked load guide with the calculator, then plan packing, departure checks, total height and the requirements of your actual journey.

Bikes, kayaks, SUPs and winter equipment

Choose around the equipment’s permitted support points and dimensions, then confirm the car, bars and complete load. These guides cover buying, compatibility and practical measurements.

Packing accessories, storage and maintenance

Plan the actual bag layout, then keep the box and its original parts clean, dry and correctly supported between trips. These guides distinguish packing accessories, model-specific replacements and storage-system requirements.
