How difficult is the overhaul effort on a roof-over situation?

In a roof-over situation, the overhaul effort can indeed be very challenging. Roof-over refers to a configuration where one roof is built over another, creating a concealed space that can trap heat, gases, and potentially undetected fire. This hidden area complicates the overhaul process because it can be difficult to access and thoroughly inspect.

Firefighters must be extra cautious in this scenario, as the presence of fire in such confined spaces can lead to unexpected flare-ups or rekindling of fire once the initial overhaul is completed. The difficulty arises not only from the physical challenges of accessing these areas but also from the need for a thorough, sometimes painstaking, examination to ensure that all heat sources have been sufficiently cooled and that the risk of re-ignition is minimized.

This complexity and the potential risks associated with working in a confined, altered roof space is what makes the overhaul effort very difficult in a roof-over situation. Firefighters must apply effective techniques and safety measures to navigate the challenges involved successfully.
