Vertical ventilation is the action of cutting a hole in the roof of a structure to allow the heat, smoke, and by-products from the fire to escape, temporarily improving interior conditions.
Increased visibility and decreased temperature can benefit trapped occupants, as well as the firefighters entering the building searching for victims. However, firefighters need to make a coordinated and rapid entry into the fire room to apply water, otherwise the fire will intensify with the renewed source of fresh air.
