Some different types of roof rails for vehicles, also called roof racks, are rain gutters, bare roof and raised rail. There is also the flushed rail and tracks.
The rain gutter roofing rack for the top of a vehicle has a cross-bar system on the roof that keeps rain from damaging the top of the vehicle. The most common type is the roof rack, which includes rubber-coated metal brackets and rubber bases to protect the car and items that are on the roof.
The raised rail is typically used with minivans and SUVs. It goes from the outer edges to the front of the vehicle with a cross-bar system.
