Frequently asked questions
Are roof bags truly waterproof?
Most roof bags are made from waterproof materials like PVC or heavy-duty nylon. However, their waterproofing depends on the quality of seams and closures. Some bags have heat-sealed seams, while others use stitching that may leak if not sealed. Look for bags with welded seams and roll-top closures for the best protection.
Can I use a cargo carrier without roof rails?
Yes. There are carriers that attach to the trunk (like trunk bags) or to a hitch receiver (like hitch baskets). Trunk bags use straps that hook into the trunk lid, and hitch carriers slide into the receiver. Ensure your vehicle has the appropriate mounting points.
How fast can I drive with a roof cargo carrier?
Most manufacturers recommend driving under 75 mph with a roof carrier. High speeds can increase wind resistance and stress on the mounts. Always check the specific guidelines for your carrier. It is also advisable to slow down in windy conditions.
Will a cargo carrier affect my fuel economy?
Yes, any external cargo carrier increases aerodynamic drag, which can lower fuel economy. Roof carriers have a greater impact than hitch carriers. Removing the carrier when not in use can help improve fuel efficiency.
Can I open my trunk or tailgate with a cargo carrier installed?
It depends on the type of carrier. Trunk bags may block the trunk opening, but many are designed to allow access. Hitch carriers may prevent the tailgate from opening fully if the carrier extends too far. Check the product specifications and user reviews for guidance.
What is the maximum weight I can put on my car’s roof?
Your vehicle’s owner’s manual will specify the maximum roof load. This includes the weight of the carrier itself plus the cargo. Typically, it ranges from 100 to 165 pounds. Never exceed this limit as it can damage the roof and affect handling.
How do I keep my cargo dry if it rains?
Choose a carrier with strong waterproofing. For soft bags, ensure all zippers are closed and straps are tightened. You can also place items in dry bags inside the carrier for extra protection. Hard-shell boxes generally provide a watertight seal.
Are cargo carriers easy to install?
Most carriers are designed for easy installation. Hard-shell boxes may require two people to lift onto the roof. Soft bags are lighter and can be installed by one person. Hitch carriers are easy to slide in and out, but you may need help lifting heavy items.
Can I use a cargo carrier for skiing or fishing gear?
Yes, many roof boxes are long enough to accommodate skis and fishing rods. Look for a carrier with a length that fits your equipment. Soft bags may not be as suitable because they lack rigid protection. Check the dimensions before purchasing.
How should I store my cargo carrier when not in use?
Hard-shell boxes are bulky and often need to be hung or placed on a stand. Soft bags can be folded and stored in a closet or garage. Always clean and dry the carrier before storage to prevent mold and mildew. Keep it in a cool, dry place away from direct sunlight.
Our take
For most car owners, the Thule Motion XT XL is the best waterproof cargo carrier because it offers the most reliable protection and ease of use. If your budget is tight, the RoofPax roof bag provides solid waterproofing at a low cost. For SUVs without roof racks, the Rightline Gear SUV Tote is a practical choice. Choose a hard-shell box if you prioritize security and durability; choose a soft bag for occasional use and easy storage.
