Assuming you install the rack and mount the skis correctly, no.
Follow these handy tips and your skis or snowboard should remain secure throughout the journey:
If you’re only loading one or two pairs of skies, position them in the middle of the rack to keep things properly balanced
Don’t load the skis with their tips facing forwards - tips facing upwards will catch more air resistance, reducing fuel efficiency as well as putting unnecessary pressure on the skis
If possible, keep your skis in their bag when transporting them on a roof rack
Leave about an inch between each pair of skis or snowboard when loading
Be careful not to overload your roof rack - manufacturers should provide guidance
It’s best to carry clean gear on your rack. Keeping dirt away from the rack should improve its durability
