In a crash the glass could shatter or get damaged but the main concern is that any occupant in the car that isn t wearing a seatbelt could be thrown out of the car and through the broken sunroof.
Panoramic roof rollover.
With this in mind a sunroof has no tangible effect on the structural rigidity or strength of a car even during a rollover.

If you re considering purchasing a vehicle with a panoramic sunroof think again.
Panoramic sunroofs are an impressive feat of engineering a large pane of glass curved to the roof s aerodynamic contours and usually made of tempered glass for its strength without added weight.
The pillars and beams absorb almost all of the forces induced during a.
If the design encompasses the entire upper structure then you do gain an advantage in the fact that there is more structural rigidity than if nothing was there at all.
Studies show when a sunroof shatters during a rollover it decreases the roofs strength compared to cars without those added features.
When it comes down to it a panoramic sunroof is essentially a giant hole in the roof of your vehicle and while they do contribute to the structural rigidity of the vehicle it ll never be as good or as strong as a vehicle with a conventional roof.
