I bought a generic hitch mounted Cargo Carrier for fifty bucks. I would suggest something like that figure out a good way to mount the bikes on it or just put them on it. It would also be useful for other things. I have deleted the roof mounted racks from all of my vehicles that I have gotten with them.
If you really wanted a roof-mounted Cargo Carrier, I would suggest a smooth relatively heavy stick of aluminum flat bar or other material with drilled tapped holes that you can thread eyelets into but remove when it was not in use it would be nearly flush with the roof but you could quickly thread some eye bolts into it. Get real fancy and you can make it over hang the back and hold something like a boat tail.
But fundamentally cargo should not go on the roof of your vehicle, it is better to store it lower for center of gravity and not in the Wind.
