How to Install a Roof Rack
Half an hour, no special tools, and three steps people skip that cause every problem afterwards.

Wash the mounting areas, assemble the feet onto the bars loosely, position the bars at the spacing your fit guide specifies, tighten to the stated torque, check the bars are square and level, then re-check the torque after the first hundred miles.
The three steps that get skipped are washing first, using the specified torque, and re-checking afterwards. Every complaint about racks creeping or marking paint traces back to one of those.

Step by step
Step 1
Read the fitting instructions for your exact kit
Fit kits are vehicle specific and the instructions carry the torque figure, the bar positions and any vehicle-specific warnings. The generic steps below do not replace them.
Step 2
Wash the mounting areas thoroughly
Clean the roof rails or the door apertures where the feet will sit, and dry them. Grit trapped between a rubber pad and paint is what causes almost all rack-related paint damage — not the clamping itself.
Step 3
Assemble the feet onto the bars, loosely
Fit the feet to the bars and leave the fasteners hand tight so everything can still slide. Fit the vehicle-specific pads or clips to the feet at this stage, checking left and right are the right way round.
Step 4
Set the bar spacing from the fit guide
Place the bars on the vehicle at the spacing the instructions specify, measuring center to center. If your carrier has a minimum mounting spread, check it now rather than after everything is tight.
Step 5
Position and square the bars
Center each bar side to side so the overhang is equal, and check the two bars are parallel by measuring the gap at both ends. A rack that is not square puts uneven load into the feet and is the usual cause of creeping.
Step 6
Tighten to the specified torque
Most systems include a torque-indicating tool or specify a value. Use it. Over-tightening does not make a rack safer — it dents door frames and distorts rails, and it is not reversible.
Step 7
Check clearances before you drive
Open every door, the hood and the tailgate fully. Confirm nothing fouls the bars or the feet. On vehicles with a powered tailgate, check it through its whole travel.
Step 8
Re-check torque after the first hundred miles
Components settle, rubber pads compress and fasteners relax. Re-check every fastener after the first hundred miles, then at the start of each season and before any long trip.
What you need
Most modern kits are designed to fit with the tool in the box, which is usually a torque-indicating key or a simple Allen key. In practice, have these to hand:
- The kit’s own tool, plus the printed instructions
- A tape measure, for spacing and for squaring the bars
- Car shampoo and a microfibre cloth
- A step, if your vehicle is tall — reaching over is how bars get dropped on paint
- A second person for the first fitting, which makes squaring far easier
You should not need a drill. If a kit asks you to drill a roof, stop and check you have the right part — mainstream systems mount without modification.
Getting the position right
Spacing. Follow the fit guide. Its figure balances stability against the vehicle’s mounting points, and it is also the figure carrier manufacturers assume.
Carrier minimums. Cargo boxes publish a minimum mounting spread. Check yours before tightening — discovering it afterwards means starting again.
Noise. Within the permitted range, further back is quieter, because air disturbed by the windshield is less energetic. Our wind noise guide covers this.
Squaring. Measure the gap between the bars at both ends. Equal means square. Unequal means uneven load into the feet, which is what causes a rack to creep along a rail over a few thousand miles.
Living with it
- Re-torque after the first hundred miles, at the start of each season, and before any long trip.
- Remove the bars between trips if you use them occasionally. It saves real fuel and stops the pads sitting wet on paint for months.
- Clean under the feet whenever you refit. This is the whole of paint protection, in one habit.
- Check the rubber pads for cracking and replace them when they harden — a perished pad transmits load unevenly.
- Measure your new loaded height and write it on a card for the glovebox. Garage doors are the most expensive part of rack ownership.
