TPO and EPDM roofing materials are manufactured in varying thicknesses from 0.045 - 0.060, with pricing acording to thickness.

I have a TPO roof. I would recommend removing the inside of the shower skylight triim or inside trim of another vent or something to get a look at the TPO. There should be some little bit left hanging over from trimming the opening. It is real thick, sturdy, more robust than what I would expect from EPDM. As for the wicking from the backing, I say that is nothing but a young wives tale. I had a leak around my skylight. When I removed it, I was able to lift up the TPO around the opening slightly. There was absolutely zero water damage around that area, no water staining, etc..
