You can always cut a slip in the membrane, but I think the EPDM is stiff and thick enought that drilling through it won't be an issue.
I'd also try to get screws into a rafter. Our roof is fiberboard and don't know how well it would hold a well nut with a solar panel that's trying to sail away.

Can you simply drill into an edpm roof or should any precautions be taken? Will the rubber twist on the drill? Getting ready to put I well nuts which will hold my solar panels in place. using 1/4-20x1/2 well nuts.
Thanks,
