Things to Consider When Securing your Car Top Carrier

Several factors go into consideration when securing your new car top carrier. Vehicle weight, make and model, weather conditions, and local laws all play a factor in having a safe journey.


Although our car roof top storage bags do not have a weight limit, it is not recommended to exceed the weight thresholds for your vehicle's roof. Some SUVs have integrated roof rack bars that allow more weight to be carried with the addition of roof rack cross bars.

Vehicle Make & Model

Car Roof bags provide a great way to store items when you are traveling. However, not all cars are made the same. The good news is that most vehicles will carry a light load on their roof without issues.

If you are planning a long journey and want to bring a lot of cargo, the first step is to ensure your vehicle can handle it. Our 23 cubic foot RoofPax car roof bag & rooftop cargo carrier gives you more than enough room to bring everything along if the vehicle in question can handle it.

Height Restrictions

Although most states will not have problems with carrying cargo on top of your vehicle, there are height restrictions to consider.

This applies to tall vehicles such as lifted SUVs and trucks. Once you have secured your RoofPax car top carrier, we recommend measuring the total height. Knowing this info will come in handy when crossing low bridges and overpasses.

Now to the most important part; safely securing your RoofPax car top carrier. We have thought of everything to help make your trip as easy as possible. Here are the steps required:

  • Make sure all straps are tight: With multiple built-in straps, there is no chance of unwanted mishaps. Once loaded, pull every trap tight to ensure a firm hold.
  • Correct placement: Where and how you place your RoofPax luggage carrier will make a big difference. Place it near the center of your car's roof and away from the edges.
  • Ensure front and rear straps are attached securely: Every RoofPax car top carrier bag comes with heavy-duty door hook straps. They go under the weatherstripping of your car's doors for ultimate holding power.
  • Use Strap Extensions if needed: If your car has a roof rack, extensions or ratchet straps will be handy. This additional step helps keep your RoofPax car top carrier firmly in place.
  • Test it Out: Before heading out, we recommend a test run. It is important to get used to the RoofPax car top carrier, so you know how it feels when loaded and on the open road. This will help you with getting used to having extra weight on your roof as well.

How to Secure a Car Top Carrier from Thieves

Car top carriers are a convenient way to expand your vehicle's storage capacity, but it's essential to secure them properly to prevent theft. Here are some tips on how to secure your car top carrier from thieves:

  1. Choose a Secure Location: When you're not using your car top carrier, consider removing it from the roof and storing it in a secure location. If that's not possible, park your vehicle in a well-lit and busy area, which can deter potential thieves.

  2. Use Lockable Straps: Invest in lockable straps designed for securing roof carriers. These straps come with built-in locks, making it difficult for thieves to tamper with them. Always lock your carrier when it's not in use.

  3. Secure the Zippers: Most car top carriers have zippers for easy access. Use small padlocks or cable locks to secure the zippers together, preventing unauthorized access to the contents.

  4. Remove Valuables: Don't leave valuable items in your car top carrier when you're not using it. Thieves are less likely to target an empty carrier.

  5. Install a Security Camera: Consider installing a dashboard camera or security camera near your vehicle. This can deter thieves and provide evidence in case of an attempted theft.

  6. Check Local Laws: Some areas may have specific regulations regarding the use of roof carriers. Be aware of local laws and adhere to them to avoid any legal issues.

  7. Use Roof Racks with Locks: If your car has roof racks, ensure they come with lockable features. This adds an extra layer of security to your car top carrier.

How to Securely Carry a Sofa on Top of the Car

Transporting a sofa on the roof of your car can be challenging, but with the right precautions, you can do it safely. Here's how to securely carry a sofa on top of your car:

  1. Measure and Prepare: Measure the dimensions of your sofa and compare them to the available space on your car's roof and roof racks. Ensure the sofa will fit without overhanging or obstructing your view.

  2. Use the Right Equipment: Invest in a roof rack system designed for carrying large items like furniture. These racks are sturdy and provide multiple anchor points for securing the sofa.

  3. Wrap and Protect: Wrap the sofa in protective materials like blankets or moving pads to prevent damage during transit. Secure the covering with straps or ropes.

  4. Secure with Ratchet Straps: Use high-quality ratchet straps to secure the sofa to the roof rack. Place the sofa on the roof rack and tighten the straps securely, ensuring the sofa is stable and won't shift during the journey.

  5. Add Extra Support: If your sofa is particularly large or heavy, consider using additional support methods. You can use wooden boards or foam blocks to distribute the weight evenly and prevent sagging or damage to the roof.

  6. Check for Clearance: Before driving, check that the sofa doesn't obstruct your view, block lights, or exceed height restrictions in your area. Ensure it's securely fastened and won't come loose during the trip.

  7. Drive Cautiously: Transporting a sofa on your car's roof changes the vehicle's dynamics. Drive at a moderate speed, avoid sudden movements, and take corners gently to maintain stability.

  8. Regularly Check Straps: Make periodic stops to inspect the straps and re-tighten them if necessary. Straps may loosen due to wind or vibrations during the journey.

  9. Secure the Loose Ends: After securing the sofa, make sure any loose strap ends are tied down or secured to prevent them from flapping in the wind.

By following these steps and taking necessary precautions, you can safely transport a sofa on top of your car while minimizing the risk of damage or accidents. Always prioritize safety and double-check your setup before hitting the road.

Final Words

By following these simple steps, you can be confident that your RoofPax car top carrier is ready for the open road. Securing your RoofPax system correctly will ensure a safe and enjoyable journey. Enjoy the ride!
