How to Stop Wind Noise from Roof Rack
Driving with roof racks can be noisy and frustrating as wind whips around crossbars and cargo boxes. The resulting whistle and roar from roof rack wind noise not only damages the serenity of your drive, but indicates lost fuel efficiency. Several techniques exist to reduce and potentially eliminate that annoying wind sound. This comprehensive guide covers roof rack noise sources, DIY remedies, product solutions, driving tips, and expert insight to achieve a peaceful, quiet ride.

Understanding Roof Rack Wind Noise
Wind noise from roof racks occur due to several aerodynamic factors:
- Airflow over crossbars creating turbulence
- Gaps around mounting feet and contact points
- Whistling around cargo box lids and tails
- Vibration of loose or unsecured cargo
The noise increases with speed as air rushes over and around rack components. Boxes and round bars produce the most noticeable whistling, while gear movements generate fluctuating roar.
“I was going crazy from the whistling and buffeting sounds my roof cargo carrier was causing on a recent road trip. A few tweaks made all the difference, and now it’s smooth, peaceful driving up top!”
DIY Remedies to Stop Roof Rack Wind Noise
Here are some easy DIY methods to eliminate or reduce wind sounds from your roof rack:
- Cover crossbar ends with old socks or tennis balls
- Fill small gaps with weatherstripping foam or rubber
- Tighten mounts and clamp contacts to minimize vibration
- Make sure all locks and covers are properly closed
- Check load is stable and secured with nets/straps
These quick fixes obstruct airflow and absorb sound through porous materials. Most can be done for under $20 in supplies and a few minutes of effort.
Wind Noise Reduction Products
Specialized products are also available to combat roof rack wind noise:
Crossbar caps – Slip over bar ends to streamline airflow. Aerodynamic shapes made of plastic or fabric.
Crossbar fairings – Attach along entire bar length. Deflect wind over instead of around bars.
Wind diffusers – Mesh screens or plates that mount to bars and disrupt turbulence.
Strips and gaskets – Adhesive rubber, foam, or felt that seals gaps and vibration points.
Cargo nets – Secures load tightly while allowing airflow through open weave. Reduces flutter.
Consult your roof rack model for compatible noise-reducing accessories made specifically for your setup.
Driving Tips to Minimize Wind Noise
Certain driving practices can also reduce whistling, roar, and turbulence from roof racks:
- Lower your speed – wind noise increases exponentially with speed
- Adjust cargo box angle for better wind deflection
- Open windows to balance interior cabin pressure
- Tighten mounts regularly – vibration worsens with use
- Remove empty cargo boxes when not needed
Being aware and proactive limits excessive wind speed over noise-prone roof structures.
Roof Rack Noise Reduction Tips Summary
| Method | Estimated Cost | Time to Install | Effectiveness |
|---|---|---|---|
| DIY gap covers | $10 | 10 minutes | Moderate |
| Crossbar caps | $15-$50 | 5 minutes | Very good |
| Fairings | $100-$300 | 1 hour | Excellent |
| Driving slower | $0 | Immediate | Very good |
