Have you ever found yourself staring at your car and thinking how to fit the new kayak or clay supply on earth? You had to leave your bike behind that time because there was no place? Have you ever considered how simple life will be with the right roof rack system?
This guide breaks what you need to know about the roof rack system. We will explore the six main types available, help you match the correct system for your vehicle and handle the burning weight area, installation and legal requirements. Towards the end, you will have all the knowledge required to make an informed decision suitable for both your lifestyle and budget.
Main Types of Roof Rack Systems
Raised Rail Roof Racks
Raised rail systems are perhaps the most recognizable type, featuring rails that sit proud of the roof surface with a visible gap underneath. You will discover them on many SUVs and wagons, where they last long from the back to the back. The nice thing about the raised rail is in their versatility – the crossbar can be distributed anywhere with the rail, giving you flexibility in load placements.
The benefits are many: Easy installation, adjustable status and wide secondary compatibility. However, they cause more wind resistance than flush -mounted alternatives, which may affect the fuel economy. They are more prone to collect dirt and debris at the bottom of the rail.
Flush Rail Roof Racks
Flush rails sit directly to the ceiling with a minimum interval, making a smooth profile compared to their raised colleagues. They have become increasingly popular on modern vehicles and offer a more integrated look still increasing flexibility. The rails typically feature specific mounting points or a continuous channel for attaching crossbars.
What sets flush rails apart is their aerodynamic advantage. With less wind resistance, you’ll notice less noise and better fuel efficiency compared to raised systems. Popular models in Australia include those fitted to the Volkswagen Tiguan, newer Honda CR-Vs, and many European wagons.
Fixed Point Roof Racks
Fixed point systems represent the gold standard for heavy-duty applications. These factory -installed growing points are used directly in the vehicle roof structure. Instead of rail, you will get reinforced attachment points that are kept strategically for maximum strength.
Benefits for using heavy duty are obvious: Better weight capacity, minimum Flex and Berg-Sle-Stability. Because they attach directly to the vehicle’s strongest points, fixed point systems can often handle loads that would overwhelm other mounting methods. They’re particularly popular with serious off-roaders and those carrying heavy trade equipment.
Track Mount Systems
Track mount systems represent the premium end of the market, featuring integrated channels or tracks built into the vehicle’s roof. These tracks allow for infinite adjustment of the crossbar position and combine the strength of fixed points with the flexibility of the railway system. It’s like being the best in both worlds.
Why choose track mount over other options? The answer lies in his incredible versatility and pure aesthetics. When not in use, the tracks are barely visible and maintain the vehicle’s smooth appearance. In addition, the ability to push the crossbar means in any situation that you can optimize the load distribution for different load types.
Gutter Mount Roof Racks
Remember those classic 4WDs with the prominent rain gutters? Gutter mount systems were designed specifically for these vehicles, clamping directly onto the strong steel gutters that run along the roof edge. Whilst less common on modern vehicles, they remain a fantastic solution for older models and classic four-wheel drives.
The strength and durability of gutter mount systems are legendary. Those old-school gutters were built tough, providing an incredibly solid mounting point. Many Lands Cruiser 70 Series owners swear by gutter mounts, as do vintage Land Rover enthusiasts. The clamping mechanism distributes load across a wide area, reducing stress points.
Bare Roof Systems
Modern vehicles increasingly come without any factory roof mounting provisions just a smooth, bare roof. Don’t worry though; bare roof systems have evolved to meet this challenge. These clever solutions use either door jamb mounts or specialised clips that grip the roof edge without damaging paint.
Door jamb Systems hooks into the door frame, use rubberized hooks that do not itch in your paint. They are removable and transferable between vehicles, making them perfect for tenants or often changing cars. Clip-on options use padded feet that sit on the roof with clips gripping under the door seal.
Which Roof Rack System Is Best for Your Vehicle?
Matching the correct rack type for your vehicle model begins by checking the car options. Keep your instruction manual or inspect a quick view. Got rails? Measure the gap to determine if they’re raised or flush. No rails? Look for those telltale plastic covers hiding fixed mounting points.
SUVs typically come with either raised or flush rails, making crossbar selection straightforward. Sedans often feature bare roofs or occasionally fixed points. Utes almost always have fixed points or tracks, designed to handle serious loads.
Budget considerations play a huge role in your decision. Basic bare roof systems start around $200-300, whilst premium track mount setups can exceed $1000. Factor in accessories too – bike carriers, kayak cradles, and cargo boxes add up quickly.
What Can You Carry on Different Roof Rack Systems?
Your roof rack opens a world of transport possibilities. Bikes are probably the most common cargo, with carriers available for everything from road bikes to hefty e-bikes. Fork-mount carriers offer the most stability, whilst wheel-mount options provide easier loading. Most systems handle 2-4 bikes comfortably.
Water sports enthusiasts will appreciate dedicated kayak and SUP carriers. J-cradles maximise roof space by carrying kayaks on their side, whilst flat cradles work better for wider sit-on-tops. Soft rack pads protect your board or kayak whilst tie-down straps secure everything. Some carriers even feature rollers for easier loading.
How Much Weight Can a Roof Rack Hold?
Understanding the difference between dynamic and static load ratings could save your life – seriously. Dynamic rating refers to weight capacity whilst driving, typically 50-100kg for most passenger vehicles. Static rating (when parked) can be 3-4 times higher, which is why rooftop tents work despite weighing more than the dynamic limit.
Calculating total safe weight requires some maths. Start with your vehicle’s maximum roof load, then subtract the rack system weight. What’s left is your cargo capacity. Never forget that weight distribution matters too – concentrate too much weight in one spot and you risk damaging the roof.
Installation and Fitting Guide
The DIY versus professional installation debate depends on your confidence and the system complexity. Basic clip-on systems are DIY-friendly, taking 30-60 minutes with basic tools. Fixed point and track systems might warrant professional installation, especially if drilling is required.
Essential equipment varies by system, but usually includes a ribbon, torque wrench and provided Allen keys. Some systems require specific torque specifications – don’t guess these! A friend to help position crossbars makes life much easier, as does working in good lighting.
Are Roof Racks Worth the Investment?
Let’s talk cost-benefit analysis. A quality rack system costs $400-800 on average but consider what it enables. Weekend camping trips become feasible, bike transport eliminates wear on car interiors, and work capacity increases significantly. For active families or tradies, the investment pays for itself quickly.
Alternative transport solutions exist but have limitations. Tow bars and hitch carriers work well but affect rear access and parking. Inside storage damages interiors and limits passenger space. Trailers offer massive capacity but require storage, registration, and towing experience. Roof racks strike the best balance for most users.
Maintenance and Care Tips
Regular inspection should become second nature. Check the growing hardware monthly for loose or rust. See voltage cracks around the growing points and inspect the rubbering for the fall. After terrain or severe weather, give everything completely once.
Rust and wear begin with appropriate installation and continue with regular care. Wash the rack system while washing the car, pay attention to joints and cracks where salt and dirt gather. Apply silicone spray to moving parts and locks. Touch any paint tile immediately to prevent rust from spreading.
Legal Requirements and Safety Standards
Australian road rules regarding roof racks are strict but sensible. Your load should not project more than 150 mm beyond the width of the vehicle or more than 1.2 meters behind the back. A red flag or red light is required to project everything from the front or backwards more than 1.2 meters. Height restrictions vary by state but generally cap at 4.3m total.
Maximum overhang limits protect both you and other road users. Front overhang cannot exceed 1.2m from the front edge of your vehicle. The rear overhang is limited to 60% of the wheelbase of the vehicle. The side overhang should not exceed 150 mm on each side. Breaking these rules leads to heavy fines and possible insurance problems.
Final Thoughts
After exploring the various roof racks systems available, you are now equipped with knowledge to make an informed decision. Whether you need a rail raised for the weekend’s tension, a heavy work system for work, or a greasy flush rail setup that balances the shape and function, is an ideal solution to wait for your car.
Key Takeaway? Don’t buy just the first racket you see. Think about your vehicle type, intended use, budget and future needs. Think about what you want to take, how many times you want to use the system, and what transfers mean something. A well-chosen roof rack changes the vehicle’s ability, opens new adventures and makes life easier.
