Waterproof Tonneau Cover

Are Tonneau Covers Waterproof? 

When searching for a waterproof tonneau cover, many truck owners quickly realize that most manufacturers describe their covers as “water-resistant” rather than fully waterproof. This distinction is important, as not all tonneau covers provide the same level of protection against moisture, rain, and snow.

Some manufacturers avoid claiming their covers are completely waterproof because they recognize the limitations in their designs. Others take a cautious approach to avoid misleading customers. The key is understanding which tonneau covers offer superior water resistance and which ones leave your truck bed vulnerable to the elements.

What Defines a Waterproof Tonneau Cover?

Not all waterproof tonneau covers for pickup trucks provide the same level of protection. To determine if a tonneau cover will keep your cargo dry, consider the following features:

  • Truck Bed Sealing System – A high-quality seal around the edges prevents water intrusion.
  • Overlapping Bed Rails – This design eliminates gaps where water can seep in.
  • Durable, High-Strength Materials – A strong, reinforced cover can withstand heavy rain and snow accumulation.

The Renegade Tonneau Cover incorporates all these elements, setting it apart from other covers on the market. With a continuous water-tight rubber seal and an overlapping structure, it provides one of the most effective barriers against water infiltration.

How to Waterproof a Tonneau Cover

Water vs. Truck Bed Cover

In your search for how to waterproof tonneau cover, you’ve seen other terms like water-resistant, weather-tight, water-repellant, and more. But it starts to seem like brands are trying to trick you into purchasing a low-performing product. When it comes to a tonneau cover, is it waterproof or bust?

While a waterproof truck bed cover might seem like the ultimate goal, this would simply mean it’s possible to submerge it. Unless you’re not planning on going deep sea diving in your truck, this feature is pretty irrelevant. So what type of protection from the weather is appropriate for your truck bed cover? 

What’s the Difference? 

At first, a cover that is water-repellant might seem just right. After all, this brings to mind a finish that will cause water to bead on it. Before you get too excited, consider this: truck bed covers that claim to be water-repellant may have a special finish, with no special attention paid to the seal at all. This leaves whatever you’re transporting vulnerable to falling rain or splashing mud. 

Wanting to protect bounty, you might be inclined to overcorrect, looking for a product that’s watertight. However, this is a feature focused on ensuring no water could get in (or out). It’s almost too focused on the seal, potential neglecting the durability of the cover itself.

This brings up the idea of weathertight truck bed covers. While this may sound promising, it is simply highlighting their ability to withstand the pressure of rain and wind. But how much pressure? They never really get around to saying. What’s more, despite having “tight” in common with watertight, something that is weathertight does not have a watertight seal. 

This leaves us with water-resistant, which, in the case of Renegade, describes the tonneau cover’s finish and its seal. Here, water is generally unable to get in, but it’s not a 100% guarantee. When it comes to the Renegade Cover, let us say this: While some small leaks are possible in theory, our users do not report noticing it happening in practice. But still, we want to be honest with you! Our tonneau cover is about 90% there. If that’s not enough for you, don’t fret, we have some ideas for how to make up that last 10%.

As you’ll see in the video review below, in intense environments, like a pressurized car wash, water may get in at each of the corners of the truck bed; even so, this is only a few drops. We recommend storing any items that are particularly sensitive away from the corners.

The other place that may leave your truck bed vulnerable is not due to the cover, but the gap where the tailgate meets the bed on the bottom. Adding a gasket sealer here is a great way to keep water and dust from getting into to your truck bed.

A product we love is called truXedo’s truXseal. Not only is it easy to install, but it works with all makes and models of trucks.

Another good option is Storystore’s Self-Adhesive Foam Insulation Tape. Most people just call it weatherstripping, and are used to seeing it around windows or doors. But this product in particular is made of the same material as a surfer’s wetsuit, Neoprene.
