Roof bars are often installed on vehicles to provide additional protection from damage caused by hail or other weather conditions.
They are usually mounted on the top of the vehicle and connected to the frame.
Roof bars are designed to absorb energy during impact and reduce the chance of injury to occupants inside the vehicle.
Roof bars are typically made of steel or aluminum. The bars are attached to the vehicle using bolts, rivets, or welded connections.
When the bars are hit by debris, they vibrate and produce a high-pitched sound. This whistling noise is normal, but it can become annoying over time.
There are several reasons why roof bars might start whistling and in this article, we’ll be going over all the possibilities and helping you solve this annoying problem!

Reasons For Roof Bars Whistling
If you can hear your roof bars whistling as you drive down the highway or even when you’re traveling slowly, it means there’s a gap between some of the panels and components that shouldn’t be there.
There are plenty of reasons that this could be the case:
- Rusting Bolts: If your roof bar has been sitting for some time without being used, rust may have formed around the bolts that hold them in place. In order to prevent rust from forming, make sure to keep your roof bars clean and free from moisture.
- Loose Bolts: If you notice that one or more of your roof bars are loose, check to see if any of the bolts holding them in place are missing. It’s possible that the bolt was damaged during installation and needs to be replaced.
- Misaligned Roof Bar Panels: If your roof bars aren’t aligned properly with the rest of your vehicle, they may not fit flush against each other. This could cause gaps where air and water can get trapped between the panels.
- Improper Installation: If you’ve had your roof bars installed improperly, they may not be securely fastened to the car. Make sure that the brackets are firmly bolted into place so that they won’t come off while driving.
How To Fix Roof Bars Whistling
Now that we understand why our roof bars might be whistling while we drive, let’s take a look at the best solutions:
Roof Rack Wind Deflectors
Wind deflectors are designed to help protect your roof bars from wind damage.
These devices are placed along the bottom edge of the roof bars and act like shields that deflect the force of the wind away from the roof bars.
They also help reduce the amount of noise produced by the roof bars.
You can buy these items separately or purchase kits that include both the deflector and the mounting hardware.
Kits are available in different sizes and shapes to accommodate most types of roof bars. You can find these products at auto parts stores, online retailers, and local dealerships.
Aerodynamic Roof Rack Crossbars
Crossbars are another option for protecting your roof bars from the wind.
These pieces attach to the roof rack crossbar and extend out past the roof bars. They are designed to help redirect airflow around the roof bars.
The aerodynamic design helps reduce the amount of noise created by the roof bars. You can choose from different styles depending on how much protection you need.
Some models feature removable covers that allow you to customize their appearance.
These products are available at many auto parts stores, online vendors, and local dealerships nationwide.
Tapered Roof Bars
Some manufacturers offer tapered roof bars that are specifically made to minimize the amount of noise they produce.
The tapers are usually angled inward toward the center of the roof bars. This reduces the amount of sound that is transmitted through the bars.
If you want to install new roof bars, it’s important to know what type of product you should use.
For example, if you’re installing a set of roof bars that were purchased from an auto parts store, you’ll probably be able to reuse the existing holes that were drilled when you first installed the bars.
However, if you’re replacing old roof bars, you’ll need to drill new holes before you can install the new ones.
To make things easier, we recommend using a kit that includes all the necessary tools and materials.
