Consult with a roofer. He may be able to build up the back end of the porch with polystyrene so that it slopes away from the house. You’ll need multiple layers of polystyrene in the back, tapering down to one layer near the front. He can hot mop roofing felt on top of this to provide waterproofing. All of this must be below your roof line so that water running off your roof will continue to the front of the porch.

An alternative would be to trim your porch support columns slightly. You should only need about 1/2 an inch per 10 feet in order to get enough drainage. However, a flat roof should be entirely sealed, so the leaking shouldn’t be happening, even with pooling. There may be more than meets the eye.
