Here's how I use to do it. On this car, the back area of the roof is what you really need to pay attention to. Use a nice mat or towel to cover the area when loading/unloading. Thule makes a great mat for this purpose. Never had any issues with the paint but if you're concerned maybe try something to buffer in between (microfiber towel?)
