How to Load a Roof Rack Safely
The roof takes less weight than almost everyone assumes. A Cranbourne West specialist explains the numbers that matter.
The two limits people miss
Your car has a roof load limit (often just 50–80 kg — in the handbook) that includes the weight of the racks themselves; and the racks have their own rating. The lower number wins. That kayak-plus-racks-plus-box adds up faster than it looks — and the limit is for driving, with dynamic loads.
Weight up high also moves the car’s centre of gravity: braking lengthens, crosswinds bite, and corners deserve extra respect.
Loading and living with it
Heaviest items low and centred between the bars, strapped to the rack (not just the load), with ratchet straps — ropes creep. Re-check straps after the first 20 minutes; wind works on everything. Remove racks when unused: they cost fuel and add wind noise for nothing.
And after carrying serious loads regularly, suspension wears faster — worth mentioning at service time.
