The number of times I've strapped anything to the roof of my vehicle (in 13 years of driving) is exactly zero. This particular vehicle might just not be suitable for your needs. Maybe eventually auto cars without roof sensors will come out, or strapping stuff to your roof will become as ridiculous as strapping something to the side of your vehicle.
