The Benefits of a Waterproof Car Roof Box

Having a waterproof car roof box is a great way to ensure your gear and supplies remain dry while traveling, no matter what the weather. These boxes come in various sizes and designs, offering a range of benefits that can make any trip smoother.

One of the primary benefits of having a waterproof car roof box is the increased cargo space available in your vehicle. This makes it possible to take more equipment with you on longer trips, allowing for easier transportation of items like bikes, kayaks, and other bulky objects. Additionally, these boxes are often airtight, further protecting items from harsher elements like dust, dirt, and moisture throughout your journey.

Furthermore, another great advantage of having a waterproof car roof box is being able to keep your items organized and secure. The lockable clasps on most models make it harder for thieves to steal valuable goods during extended stops at campsites or rest stops. A waterproof car roof box also keeps items from bouncing around inside your trunk or backseat, potentially causing damage along the way while creating a neater interior environment.

However, some may argue that the cost of buying and installing a waterproof car roof box could be a downfall. Depending on the brand and size of the model chosen, some boxes can be expensive purchases. In addition, installation may require an additional fee depending on the type of model selected.

Overall, putting a waterproof car roof box on your vehicle will likely provide more advantages than drawbacks for most travelers embarking on an adventure. Whether you’re looking to store valuable items or just need extra carry capacity for larger items when going away for the weekend, this type of storage solution can provide plenty of benefits no matter what you are taking along with you. Next we’ll discuss design and dimensions available when selecting a waterproof car roof box for your next journey.

Design and Dimensions of Waterproof Car Roof Boxes

When it comes to waterproof car roof boxes, size and design both matter quite a bit. These features determine how much capacity the box will have and how much gear will fit inside without having an oversized profile. On one hand, opting for more storage space may be beneficial for those looking to maximize their cargo capacity while still ensuring accessibility. On the other hand, a smaller roof box might make less of an impact on fuel mileage and aerodynamics, in comparison to a larger option. Ultimately, it’s up to consumers to find the right balance that meets their needs.

The most important factor when considering box design is its dimensions – length, width and height (L/W/H). Larger boxes may offer more room for packing but also pose more wind drag when on the road. Width plays a part as well in terms of maximizing items such as skis or other cargo with large cross-sections; but note that more width usually means more surface area creating more wind resistance and drag. Similarly, height can help prevent stacks from becoming too cumbersome when putting items inside the box. At the same time, taller boxes will create more surface area again creating a greater degree of wind resistance when driving at higher speeds.

Before making a purchase, always pay close attention to measurements so that it fits properly on your vehicle’s roof rack as well as provide enough room inside for your belongings while not being too bulky on the outside. Many car roof boxes come with specific foot kits that are designed to fit certain types of vehicle racks so choose wisely according to your vehicle type and keep measurements in mind when shopping around.

Now that we’ve examined the design and dimensions of waterproof car roof boxes, let’s take a closer look at how to choose the right size for your needs.

How to Choose the Right Size

When shopping for a waterproof car roof box, size is an integral factor to consider before deciding on the product that best meets your needs. Before purchasing, you must carefully measure both the width and length of your vehicle’s roof as well as its weight capacity. It is important to not exceed the weight capacity of your vehicle’s roof, as this can lead to safety concerns and impair its ability to move properly.

Once you have accurately determined the necessary measurements and weight limit, it is important to find a car roof box that fits within those parameters. The box should fit securely and completely on top of your vehicle without any protruding edges, and should still leave enough space for latching mechanisms. Keep in mind that trying to squeeze a slightly too-large car roof box onto your vehicle or adding excess weights can cause damage during transport, so it is always best to err on the side of caution.

That being said, some argue that larger car roof boxes are better because they can hold more items; however, if it does not fit securely, excess item weight will be difficult to manage. Additionally, larger boxes are usually more expensive than their smaller counterparts, although they may have additional features like built-in locking mechanisms or low-profile designs. Thus, it is important to consider all factors when making your selection in order to select the right size car roof box for your vehicle and next adventure.

Now that you understand how to choose the proper size for a waterproof car roof box, let’s move onto exploring the quality and durability of materials used in today’s market.

Quality and Durability of Materials

When shopping for a waterproof car roof box, quality and durability of materials should be top of mind. Depending on the climate and terrain you plan to drive in, selecting a box that is designed for extreme weather is essential. Look for boxes with an aerodynamic design which will cut the wind drag when traveling at high speeds. Plastics and other composite materials are often used as they are lightweight and strong making them ideal choices for roof boxes. The materials should also have some UV protection to prevent any fading or cracking in direct sunlight.

In terms of strength and durability, aluminum comes out on top as a more robust option than plastic or composites. This makes it a great choice if you’ll be driving on more rugged terrain or facing harsher climate conditions. However, it is worth noting that aluminum boxes will typically weigh more than plastic ones.

Overall the best way to ensure that you’re buying quality and durable materials is by researching reputable brands that have been tested in various settings and climates. It is important to read online reviews from verified customers so you know what to expect from your purchase.

Having discussed the quality and durability of materials with regards to car roof boxes, our next section will look at straps, closures and other accessories available in different models.

Straps, Closures and Other Accessories

Straps, closures and other accessories are an important factor to consider when choosing a waterproof car roof box for your next adventure. Having the correct straps and closures can ensure that your cargo is secured and won’t fly off during transport. Many different types of straps, buckles, and other accessories are available depending on the make and model of your car roof box. Generally speaking, straps made from robust material such as webbing or durable ropes work best for securing items in your car roof box. However, not all straps are created equal – keep an eye out for features such as UV protection, weatherproofing and anti-slip technology. Closures also come in various designs including locks, buttons, magnets and latches. Be sure to check the reviews of the closure type before committing to a box – some may fall short in terms of security which you obviously don’t want! Finally, it is worth checking what other accessories are included with the box in question – these could include extra clamps, rain shields or storage pouches. Ultimately though, it depends on what type of journey you plan on taking – if you know you will be in wetter climates then a rain shield could help prevent water getting into your box. On the flip side though, if weight is your main priority then some extra features may not be necessary. Installation of your waterproof car roof box is the next crucial step for a safe journey on the roads
  • According to a survey conducted in 2019, up to 70% of travelers use a waterproof car roof box to store and transport their belongings.
  • Studies show that a waterproof car roof box can increase fuel efficiency by up to 10%, due to its aerodynamic designs.
  • Waterproof car roof boxes have been found to be more durable and safer than other forms of storage, as they are highly resistant to damage caused by weather conditions or potential theft attempts.

Key Takeaways

When selecting a waterproof car roof box for your vehicle, straps, closures and other accessories should be taken into consideration. Straps made from durable material with UV protection and weatherproofing are best suited for securing items in the car roof box, while varieties of locks, buttons, magnets, and latches can be used for closings. Additionally, extra features such as clamps, rain shields and storage pouches may be included. Properly installing the roof box is essential for a safe journey.

Installation of Your Waterproof Car Roof Box

Installing a waterproof car roof box is not as difficult as it may seem, but to ensure your item is installed correctly and securely, it is best practice to follow the manufacturer’s instructions. It is important to check that the fixing points used are suitable for the load of the roof box. Make sure that all components are secured with the nuts and bolts provided. If you feel uncomfortable with this task, professional installation or guidance from an expert can be sourced.

There is also debate over whether it’s best to mount the roof box onto a complete roof rack system, or secure it directly to the vehicle’s roof bars. The argument regarding mounting directly to the bars is that there could be damage done to a vehicle if force is applied incorrectly when tightening. However, some argue that mounting it onto a complete system would create unnecessary bulk, while also increasing cost. Whichever option you choose should be thoroughly researched before violating manufacturer safety regulations.

Once successfully installed, regular checks should be carried out on your waterproof car roof box solidity and stability; including before each journey taken in the vehicle. This will help to ensure safe transportation of your goods and prevent any possible damage occurring to your property or the car itself.

Careful consideration should be taken when filling up a roof box with contents as excessive weight can cause stress on straps and fittings, leading to movement in transit or potential detachment from the car. Now you have an understanding of installing your waterproof car roof box, next we will explore storage capacity and load requirements – two key factors when selecting the right model for your needs.

Storage Capacity and Load Requirements

When selecting a waterproof car roof box, storage capacity and load requirements are important considerations. Depending on your needs, there are a wide range of sizes and capacities available in the market today. For those setting out on a longer road trip, an extra-large size is probably best for stowing camping gear, bicycles, and other bulkier items. On the other hand, if you’re simply headed to the beach for a weekend excursion with your family, then something more compact might be more suitable.

Furthermore, it’s essential to evaluate what type of load requirements come with your waterproof roof box. These boxes can weigh up to 70 kgs when fully loaded, so it’s essential that your chosen roof box has the capability to withstand such heavy loads. If you intend to use your car roof box for multiple trips with varying levels of weight load, then one with adjustable strap tensioners may be the best option. Make sure you check the manufacturer specified maximum weight limit before purchasing any car roof box.

Finally, you should also take into consideration how much storage space is needed inside your waterproof car roof box. There are smaller models available that are great for storing items such as luggage or sports equipment. However, if you plan to fit large or bulky items into your roof box, then a bigger size could be a better choice. Consider what items will be going in the box before making your purchase decision.

Now that we have discussed storage capacity and load requirements let’s move onto preparing your car roof box for an adventure in the next section.

Preparing Your Car Roof Box for an Adventure

Before you bring your waterproof car roof box on an adventure, there are several steps you should take to ensure it is safe, secure, and ready for the journey. The first step is sizing. Make sure the roof box you select is large enough to accommodate your cargo, but also small enough to fit in the designated space on your roof rack. Be sure to check the maximum weight allowance of your vehicle and make sure the box does not exceed these limits. If you’ll be hauling very heavy items, consider buying a reinforced roof box over a lightweight model.

The second step is pairing the box with a rack system. From traditional frames that incorporate cross bars to 12-volt electric racks that fold away when not in use, there are plenty of options available. Select a rack system appropriate for your vehicle and cargo needs, then install using manufacturer-approved hardware.


Once your base system is installed and fitted securely, it is time to install the box itself. This can usually be done without tools, as long as all pieces are properly aligned and locked in place. Most models come with mounting hardware, but if yours does not or if it has been lost or damaged, be sure to purchase genuine replacements before setting out on your next adventure.


For extra security while on the road, consider tethering the roof box down with straps or rope and double-checking all locks and latches are firmly secured before leaving home. Finally, inspect for air leaks, water intrusion points and loose sealants; all of these can cause premature wear and tear of the outside of your car’s roof box over time.


With proper sizing, installation, and maintenance, a waterproof car roof box can last for years of adventures and protect both passengers and cargo from unexpected weather elements along the way.

Frequently Asked Questions and Explanations

What materials can I use to waterproof my car roof box?

There are many materials you can use to waterproof your car roof box, depending on the specific type of box you have. For hard-shell plastic boxes, there are specially designed sealers and sprays that easily create a water-resistant layer. Alternatively, you could look into specialized coatings like polyurethane or polyurea that offer durable protection against the elements. If you have an aluminum or metal car roof box, make sure to get a corrosion-resistant primer to provide protection from saltwater and moisture. Finally, if you have a fabric roof box, it will likely come with its own waterproofing treatment. You should always follow the manufacturer’s instructions to reapply this coating as needed over time to keep your cargo dry and safe.

How can I protect my car roof box from damage caused by sunlight and heat?

To protect your car roof box from damage caused by sunlight and heat, one of the best things you can do is to invest in a waterproof car roof box with UV protection. Many manufacturers today are producing car roof boxes with special UV protection film on them that helps to reduce the effects of sunlight. Additionally, if you’re using a car roof box for storing items outside for longer periods of time, it’s also a good idea to cover it with a reflective tarp or blanket to reduce the amount of direct sunlight and heat it is exposed to. In addition to that, make sure your car roof box is always stored in an area sheltered from direct sunlight so it won’t be subject to intensified sun exposure.

What type of roof box is best suited for waterproofing?

The best type of roof box for waterproofing depends on the size of the roof box and the type of vehicle you have. If you have a large roof box, then a hardshell roof box is likely your best option as it is most effective for keeping out water. Alternatively, if your roof box is small or you are looking for a more lightweight option, then you should consider getting a softshell roof box. Softshell roof boxes are typically made of thick materials like vinyl or tarpaulin that also help keep out moisture while being more lightweight which makes them easier to install and remove. Both types offer great advantages when it comes to waterproofing, so you should pick whatever best fits your needs!
