Ceiling/Roof
• The construction of false ceilings/roofs can be either internal or external.
• Observe the distance between the top of the corner block and the top of the roof, e.g., normally the roof is slightly below or flush with the top of the corner blocks.
• Ensure that the ventilation holes are visible, not covered or absent.
• Look for repairs on the ceiling/roof that are visible on the inside and outside of the container.
• Use a tool to tap on the ceiling/roof, there should be a hollow sound.
