Replying to Roof Racks

Good morning, NS.

I just had a question about roof racks. I currently have to set my skis in my car at an angle, going from behind the driver to the front passenger, and they barely fit. I can't fit another person in there. I have a coupe, with no rails on the top. I've taken a look around for stuff, but have come to the conclusion that I would need to install rails in order to have a roof rack.

Is that true? Or is there some hidden secret that NS has knowledge of, but no one else does?

Also, on when I searched for Roof Racks on here, I noticed that it isn't uncommon for them to fall off on the highway. Is that because of someone not paying attention when putting them up, or is it just a defect that will happen with most racks?

Thanks
