Yes, you can leave roof rack pads on year-round, but UV exposure, moisture, and road grime will shorten their lifespan significantly if you do — removing them when not in active use is the smarter call.

Roof rack pads sit in direct sunlight and absorb road spray every mile. Even pads built with anti-UV coating, like the 600D oxford fabric on Hikula's 28" aero pads, will fade and degrade faster under constant exposure than pads that are stored between uses. Water pooling under a pad that stays on through wet seasons can also cause the velcro closure to lose grip over time, which matters for highway-speed security.

  • Hikula 28" roof rack pads use 600D oxford fabric with an anti-UV coating to resist fading and cracking.
  • Hikula roof rack pads are designed for aero-profile crossbars 2–2.875 inches wide, not standard round bars.
  • The dual closure system uses heavy-duty velcro plus silicone/metal buckle straps rated for highway speeds.
  • Prolonged UV and moisture exposure degrades velcro grip strength, reducing pad security on the crossbar over time.

Important Exceptions

  • Winter road salt regions: If you drive roads treated with brine or salt, leaving Hikula roof rack pads on accelerates fabric and buckle corrosion — remove and rinse after any salted-road exposure.
  • Car washes with high-pressure jets: Automated high-pressure washes force water under the velcro closure and into the pad seams; remove the pads before running the car through.
  • Vehicles parked outdoors full-time in desert climates: Anti-UV coating on 600D oxford fabric slows degradation, but sustained 100°F+ heat with intense solar load will crack the fabric faster than the coating can offset — storage between uses matters more in these conditions.
  • Aero crossbars with a wax or slick coating applied: If you've waxed your crossbars, the velcro closure loses its anchor point — the pad can shift even at low speeds regardless of how long it's been on the bar.

Common Mistakes

  • Leaving pads on through winter storage: People often keep pads mounted during months the vehicle sits unused, which accelerates velcro and fabric degradation without any benefit.
  • Skipping the buckle straps and relying on velcro alone: People often skip tightening the silicone buckle straps on Hikula's 28" aero pads, letting velcro carry the full load — which fails at highway speeds over time.
  • Not rinsing pads after salt-road or coastal exposure: Road salt and coastal spray embed in the 600D oxford fabric and accelerate thread breakdown, cutting pad lifespan significantly across a single winter season.
  • Storing pads folded tightly while still damp: People often pull Hikula roof rack pads off in wet weather and fold them straight into storage, trapping moisture in the fabric layers and promoting mildew that weakens the material.
  • Ignoring velcro lint buildup: Road debris fills velcro hooks gradually, and people rarely clear it — once grip strength drops noticeably, the pad can shift on the crossbar at speed before the problem is obvious.
