Yes there are two drains at the front and two at the rear. The front drains can be checked by pouring a small amount of water ie small paper cup worth at each corner and see if it comes out from behind the body trim panel just rear of the front tires. you can check the rear drains parking nose up on a slight incline and pouring water at each side of the sunroof tray.
the felt seal that goes around the opening does not stop water completely it just slows the flow, that's why the drains are there. To access the rear drain tubes where they attach to the roof tray requires removing the headliner.

The drain tubes are #56 in the picture (only one each front and rear pictured)
I hope this helps, Robert
