I cannot say that I've ever seen a moon/sun roof just randomly shatter. I would presume that something hit it, but I'm not sure what. I don't really see how tint would cause this, and if it did then SOA would be responsible as it comes standard tinted. Good luck OP, let us know what happens.
Edit: Is that a crater I see in the moon roof hood?
