2010 Skoda Fabia Roof Rails - Help

[Rob94Red]

Hi, I have a 2010 Skoda Fabia TSI and am looking to get a roof tent box to go travelling.
My car doesn't have any roof bars to attach the roof tent box to do I'm just left with the option of the roof bars that clamp around the edge of the roof between the doors. I've found these to not be very secure.
Can anyone advise please where I can find roof rails to fit my car and advise on how best to fit them onto the roof? Can I just drill holes in the roof and screw them on?

I’m fairly sure normally there are bolt holes or indents hidden behind the door seals to fix roof bars to.

I wouldn’t be going drilling any holes in your car
