You can raise a car's center of gravity by loading a roof rack with items. 
A roof rack with load will indeed raise the center of gravity and make the vehicle more prone to tipping. 
To be safe look at the vehicle's manual regarding load limit on roof rack, you never want to put too much up there, because it will raise the center of gravity on your vehicle, causing the vehicle to be more prone to tipping over on turns. Try to put as much as possible inside of the vehicle to keep the center of gravity lower. 
Be careful, as raising the vehicle will also raise your center of gravity, which will make the vehicle a little more prone to tipping.
