Sealing my roof, what product is best

I did not know that, how can you tell? Mine is a big skylight around 2 ft x 4 ft.

On mine, the top layer of the skylight is level with the roof, the inside over the shower is level with the ceiling. I know the plastic isn't two or more inches thick, so it must be double walled.

Here is a picture of the 'in process' repair that we did on our rig around the skylight. You can see from here that it is double-walled as there is the roof portion and the portion also inside the shower that is screwed in separately.
