The above picture is a good example of solid screw mount. Only thing I would add is that it should have a thin layer of Dicor sealant under the metal, as well as a good coating on top of the metal and screws.
More and more people are using 3M double sided tape instead, though. This precludes having any holes at all in the roof. I have never heard of a solar panel mount failure in using double sided tape, either.
not sure I'd trust tape on a EPDM roof. metal or fiberglass yes, but on a rubber roof your assuming that the glue between the rubber material and roof is designed is stronger enough to not release.
