Before you embark on a roof conversion project, it’s essential to understand the various types available.

Considerations Before Starting

While roof conversions are undoubtedly advantageous, there are some important considerations to keep in mind:


  • Weight limit – Be aware of your 4×4’s roof weight capacity, as exceeding it can affect stability and safety.
  • Installation – Roof conversions require proper installation to ensure they are secure and safe.
  • Height clearance – Consider the increased height of your vehicle with a roof conversion, especially when driving in low-clearance areas.
  • Aerodynamics – Roof conversions can affect your vehicle’s aerodynamics and fuel efficiency. Some accessories can mitigate this impact.
  • Legal regulations – Familiarise yourself with local regulations regarding roof loads and road safety.

The Installation Process

Installing a roof conversion typically involves the following steps:


  1. Assessment – Assess your 4×4’s roof structure to determine compatibility with the chosen conversion type.
  2. Mounting – Follow the manufacturer’s instructions to securely mount the roof conversion. Ensure it’s level and well-secured.
  3. Safety checks – Double-check the installation for stability and safety. Test the conversion’s weight capacity before loading it.
  4. Weatherproofing – Depending on the type of conversion, consider adding weatherproofing measures to protect your cargo from rain, dust and other elements.
