When accessing a roof in a building that exceeds a specified height, ensuring that roof access is accomplished through the interior is crucial for a number of safety and regulatory reasons.

Interior access often allows for a safer and more controlled method of reaching the roof. This approach typically includes the use of designated stairways or lifts that comply with building codes and safety standards. Additionally, accessing the roof from the interior reduces the risks associated with outdoor conditions, such as weather hazards and unsecured surfaces, which can lead to accidents.

In situations where roof access is planned, particularly in taller structures, it is essential to adhere to safety protocols that prioritize worker safety and compliance with local regulations. By ensuring access is from inside the building, the risks associated with using an external ladder or needing to navigate challenges on the exterior of the building can be effectively mitigated.

Choosing only an exterior ladder may not provide adequate safety measures or structural support, while accessing from the basement level does not provide a practical route to the roof and could complicate the access process. Moreover, the notion that no access is required if the height exceeds a certain limit undermines necessary safety practices and would likely be in direct violation of codes and regulations that govern roof access in tall buildings.
