Hard epoxy on roof?

Looking for roof repair advice:

There are couple small leaks in my roof and whatever coating is on there doesn't seem very sturdy. There is a black rubber layer (EDPM?) covered with a very thin layer of a white sealant. This white sealant expands and bubbles when it gets wet and scrapes off fairly easily.

I have a few cans of garage floor epoxy that is very sturdy that I was thinking of applying to the roof. My main concern is that it's brittle and doesn't flex very much. Is this a bad idea? I'm wondering because I haven't seen that anyone else seem to go this route.

Thanks!
Bob
  • As a short term fix I sprayed some automotive underbody sealant on the cracks, meant to prevent rust, etc. on the undersides of cars. Kind of an asphalt smelling, heavy black sealant. Not sure if that was a great idea but it seems to have sealed pretty well. Hopefully there won't be any unexpected chemical reactions...
