Ways To Fix Tonneau Cover Leaking

Drainage Water Pipes Can Be Installed

One of the most straightforward fixes is to install drainage water pipes on both sides. This way, when it rains or snows, excess moisture will drain away from your tonneau cover instead of getting trapped underneath and causing leaks.

Install Extra Seals

If the leak is small, you can try to add extra seals around the cover. This is a quick and easy solution that will help with smaller leaks, or if you want fixed small holes, this might be a good option for you!

Add an Extra Layer of Protection 

If your tonneau cover has an issue with being leaked by things such as nails or other sharp objects, then adding an extra layer of protection underneath the cover is a great idea. This will help to stop anything from penetrating your tonneau and causing it to leak!

Using A Tonneau Cover Flap That Helps To Seal The Edge

If you want to keep things simple when fixing leaks in your tonneau cover, consider using a tonneau cover flap that will help to seal the edge. This is one of the easiest ways to stop leaks because it doesn’t require any extra work besides installing the flap onto your existing cover!

Make Tonneau Cover Waterproof

You can make your tonneau cover water-resistant by spraying it with Scotchgard and letting it dry overnight before putting the tonneau in place. You can do this about once every six months for maximum waterproofing protection, but doing it more often will not hurt anything either. 

It’s also important to clean your tonneau cover regularly, especially if you often drive in dusty or muddy conditions. If it is stored wet, dirt will get into the fibers and cause permanent damage over time. This could lead to rips and tears that can let water seep through more easily than before.

Test and Repeat

After doing all those things or one of them, you need to check if the leak is still there. Create a fake rain using a water hose & check the tonneau cover. If it is still leaking then repeat the process.

If there is still a leak, you need to use one of those methods again to fix the issue. Otherwise, it would be best if you bought a new sealing to change the whole leather cover.


I hope this blog post will help you to fix the leaking tonneau cover easily & quickly. There are several ways to fix this problem, so you just need to choose the most suitable method for your tonneau cover. If you have any questions about fixing a leaking tonneau cover or waterproofing your leather, feel free to leave them in the comments!

After doing all those things or one of them, you should recheck the leak to see if it’s fixed! If there are still leaks, then repeat the process until your tonneau cover is no longer leaking.

Frequently Asked Questions (FAQ)

Are tonneau covers supposed to leak?
The answer is both yes and no. Here’s a little more information to help you understand why.
Tonneau covers are designed to keep your cargo dry and protected from the elements, but they’re not perfect. Water can seep in through the seams or around the edges, especially in heavy rain or if the cover isn’t properly sealed.
To prevent leaks, make sure your cover is installed correctly and that all the seals are tight. You can also buy a cover with a built-in drainage system that helps channel water away from your cargo area.

Do bed covers leak?
One common cause of leaking bed covers is an improperly fitting cover. If your cover is too big or too small, it may not fit snugly against your mattress, leaving gaps that allow water to seep through. Make sure to measure your mattress before purchasing a cover, and be sure to choose one that fits snugly.

If you have a tonneau cover that’s seen better days, you might be wondering if it’s possible to replace it. The good news is that yes, you can replace your tonneau cover! Whether you’re looking for a new cover because yours is damaged or simply because you want to upgrade to a newer model, there are plenty of options available on the market.
If you have a tonneau cover, you may be wondering if it’s safe to go through a car wash. The answer is yes! Tonneau covers are designed to withstand the rigors of a car wash, so you can rest assured that your cover will be just fine. Just make sure to close the cover before going through the wash, and you’ll be good to go.
