I had a leak on mine and upon fixing it (it was leaking on the right front corner) I found that the thin sheet of fiberglass is basically lying on the roof and secured at the edges. It is possible that on the side of the front left or right corner the fiberglass is lifting up a little and "filling" the void between the roof and the laminate with air while you drive. That area (the front left and right corners) is a slight slope down so it's unlikely water would travel uphill under the laminate unless it is pouring down rain while you are driving.
