Fixed roofs are permanently affixed to the top of the tank, which creates a great deal more space for vapors to accumulate when the tank is less than full. The less material in the tank, the more room for vapors to build up. Floating-roofs float on the top of the material, guided by support legs and sealed with vapor seals around the rim.
