What is the cleanest way to mount a satellite dish to the roof? I notice that most times, the DirecTV installer will just run the cables down the side of the house, drill a hole to where the televisions will be, and voila, he's done. I'd rather just have the cables go straight into the attic and do the wiring inside. I'm concerned about drilling into the roof, though - afraid of leaks. Do you mount a plate on the underside of an overhang, run the wires to it, and then run everything inside from there? Any suggestions (or pictures) would be appreciated.
