Are Tonneau Covers Waterproof?

Are you ready to tackle the great outdoors, rain or shine, without worrying about your cargo getting soaked? If you’re a ute or pickup truck owner, investing in a tonneau cover is a no-brainer for protecting your gear. But the burning question remains: Are tonneau covers waterproof? Let’s dive into the details and find out!

What Are Tonneau Covers?

Before we get into the nitty-gritty of waterproofing, let's quickly review what tonneau covers are all about. Tonneau covers, also known as Roll covers, serve as a protective layer over the bed of your ute. They come in various styles, including soft tonneau cover, hard folding, retractable, and more, offering different levels of security and accessibility.

Are Tonneau Covers Waterproof?

When a customer is interested in a Tonneau cover, one of the first questions they will ask is “Is it waterproof?”. The short answer to this question is, when properly installed, a tonneau cover will offer water resistance, keeping the vast majority of water from entering your ute’s bed. To describe a tonneau cover as 100% watertight or waterproof would be inaccurate, as there are quite a few variable to this; intensity of rain, length of rain storm and angle of the vehicle when parked. 

Importance of Waterproofing

Waterproofing is paramount when it comes to tonneau covers. Picture this: you've packed your ute bed with camping essentials, tools, or groceries, only to encounter a sudden rainstorm. Without proper waterproofing, your cargo could end up soaked and damaged. Taking the right precautions will help ensure your belongings remain dry and shielded from the elements, offering you peace of mind regardless of weather conditions.

5 Tips for Improving Waterproofing

Choose the Right Material: Opt for tonneau covers made from durable, weather resistant materials like vinyl or aluminium. These materials offer superior protection against moisture intrusion.

Seal the Edges: Check for any gaps or seams where water might seep through and use aftermarket sealants or weather stripping to seal them tight.

Add Drainage Systems: Installing drainage channels or tubes can help redirect water away from the ute bed, preventing pooling and potential leaks.

Regular Cleaning/Maintenance: Maintain peak performance by keeping your tonneau cover pristine and debris-free. Stay vigilant by inspecting and promptly replacing any worn seals or damaged components. Additionally, don't forget to prioritise the regular cleaning and upkeep of the roll cover's canister for optimal functionality.

Consider Retractable Covers: Retractable tonneau covers, when properly installed and maintained, offer excellent weather resistant capabilities due to their seamless, one-piece design.



So, are tonneau covers waterproof? The verdict is that while they are not 100% waterproof, with the right precautions and maintenance, you can significantly minimise water infiltration. Investing in a high-quality pickup truck bed cover and following these tips will ensure your cargo stays dry and protected on all your off-road adventures.
