How much weight can you put on a Subaru Outback roof?

The typical published roof load limit for most Subaru Outback models is around 150 pounds (68 kilograms), including the weight of roof racks and cargo. However, the exact limit can vary by model year, trim, and roof hardware, so always verify the figure for your specific vehicle in the owner's manual or on the door jamb placard.

A precise figure depends on your exact year and configuration. The roof load rating is a static limit that encompasses the rack system and any cargo loaded on top, and dynamic driving forces can reduce the safe margin. Always confirm the exact value for your vehicle before mounting gear or cargo.

Understanding the roof load limit

The roof load limit represents the maximum combined weight that the roof can safely support when the vehicle is stationary, including the weight of the roof rails or crossbars and any cargo carried on them. Driving dynamics—such as braking, cornering, and wind forces—mean the practical safe limit can be lower, so operators are advised to stay well within the published rating and secure items properly.

What counts toward the limit

The limit includes the weight of the roof rack hardware (feet, crossbars, and any mounting hardware) plus the cargo loaded on top. When calculating what you can carry, you should add the rack weight to the cargo weight and ensure the total does not exceed the published maximum for your specific vehicle.

Year-to-year variation

While around 150 pounds (68 kg) is common, some model years or roof configurations may show different limits. Always check the exact specification for your Outback’s year and trim in the owner's manual or on the door jamb placard, and contact Subaru support if you’re uncertain.

How to verify your Outback’s roof load limit

To load safely, confirm the official limit for your exact vehicle and then plan accordingly. Here are steps to verify:

• Consult the owner's manual for the explicit "Roof load" or "Maximum cargo weight on roof" specification, including the unit (lb or kg).


• Check the driver’s door jamb placard, which often repeats or supplements the roof load rating.


• Include the weight of the roof rack system itself when calculating total load.


• Sum the rack weight and cargo to ensure the total remains at or below the published limit.


• Consider dynamic loading and distribute weight evenly along the roof to minimize stress.

With the official limit confirmed, you can plan cargo loading more safely and avoid overloading the roof structure or rack hardware.

Loading guidelines and best practices

To stay within safe limits and maintain vehicle handling, follow these guidelines:

• Use a roof rack and crossbars that are rated to carry the total intended load, and ensure they are properly installed according to the manufacturer’s instructions.


• Distribute weight evenly along the length of the roof and keep heavier items closer to the center to reduce stress on the rails.


• Secure all cargo with multiple reliable tie-downs or straps; check them periodically during travel.


• Avoid placing heavy items high up on the roof to keep the vehicle’s center of gravity as low as possible.


• Be mindful of wind resistance and driving speed; heavy, high-profile loads can affect handling and fuel economy.

Following these guidelines helps ensure you stay within the vehicle’s capabilities and reduces risk of damage or handling issues while driving.

Practical tips for safe loading

Additional practical suggestions to enhance safety when using a roof rack:

• Choose a roof rack system with solid mounting and a proven weight rating compatible with your load.


• Place the heaviest items inboard (closer to the vehicle center) and as low as possible to lower the center of gravity.


• Double-check straps, knots, and anchor points; secure cargo before every trip and re-check after long drives or rough roads.


• Regularly inspect roof rails and crossbars for signs of wear or damage and replace any compromised components before loading again.

If your cargo routinely approaches or exceeds the published limit, consider alternatives to roof loading to protect both performance and safety.

Alternative cargo options

When heavy or bulky loads threaten to exceed the roof limit or impact handling, consider these alternatives:

• hitch-mounted cargo carriers or baskets, which keep weight off the roof while providing comparable carrying capacity (and often easy offloads).


• Using the vehicle’s interior cargo space or rear hatch storage when feasible, especially for smaller items or gear.


• Distributing multi-trip loads across separate trips to minimize roof load per trip.

Consult a professional if you anticipate regular loads near the limit, as they can help optimize mounting solutions and ensure safety.

Summary

For most Subaru Outback models, the roof load limit is about 150 pounds (68 kg), including rack weight and cargo. Exact figures vary by year, trim, and roof hardware, so always verify in the owner’s manual or the door jamb placard for your specific vehicle. Plan loads carefully, distribute weight evenly, secure cargo properly, and consider roof-free alternatives if you regularly approach the limit. Proper loading preserves safety, handling, and the longevity of roof hardware.

How much weight can my car roof support?

A car's roof can safely hold an average of 75-220 pounds of dynamic weight (while driving), but the exact limit depends on the vehicle's make and model, and is typically much lower than the static weight capacity (when stationary). It is crucial to check the vehicle's owner's manual or manufacturer's website for specific ratings and to remember that the total weight includes the weight of the roof rack, cargo box, and any other accessories. Overloading can cause damage and be dangerous, so always stay within the lowest limit provided by the manufacturer.
 
Key factors determining roof weight capacity

• Vehicle model: This is the most important factor. Compact cars have lower limits (e.g., 75-100 lbs dynamic), while SUVs and trucks can have higher limits (e.g., 150-200+ lbs dynamic). 
• Dynamic vs. static weight: Dynamic weight is the limit while driving, while static weight is the limit when the vehicle is stationary. Static limits are often much higher (e.g., a vehicle might hold 650 lbs when parked but only 176 lbs while driving). 
• Weight of accessories: The total weight you can carry is the car's limit minus the weight of any equipment like a roof rack, crossbars, or a cargo box. For example, if a roof has a 140 lb dynamic limit and the rack weighs 40 lbs, you can only load 100 lbs of gear. 
• Road conditions: The dynamic load rating should be reduced on rough roads or trails, as the suspension activity puts extra stress on the roof. 

How to find your vehicle's specific limit

• Check the owner's manual: This is the most reliable source for your vehicle's specific dynamic and static load limits. 
• Look for manufacturer information: The vehicle manufacturer's website often provides specifications for different models. 
• Check the roof rack or cargo box instructions: The equipment you add may have its own weight rating, which is also a limiting factor. 

Important considerations

• Weight distribution: Distribute weight evenly across the crossbars, ideally placing about 60% of the weight in the center. 
• Safety: Exceeding the weight limit can affect your vehicle's stability and handling, and can cause damage to the roof and its components. 

What is the weight limit on the roof of a 2017 Subaru Outback?

176 lbs
The maximum load limit of the cargo, roof rack and carrying attachments must not exceed 176 lbs( 80 kg). Place the heaviest load at the bottom, nearest the roof, and evenly distribute the cargo. Always properly secure all cargo.

How much weight can the crossbars hold on a Subaru Outback?

150-pound
Factory Crossbars: Handy, But Limited
It's a smart and convenient setup for lighter gear. These work just fine for hauling a cargo box, a few duffel bags, or even your snowboard. With a 150-pound dynamic load rating (and up to 700 pounds static while parked), they're capable enough for simple tasks.

Can I put a roof top tent on a Subaru Outback?

You will need an aftermarket roof rack rated for the dynamic load of whatever the RTT you're buying weighs. Do not rely on factory crossbars, they are not rated for it. The only Outback that has a properly rated roof rack for rooftop tent usage is the Wilderness.
