The fixed components such as membranes that contribute to the weight of the roof are called:

• A. Dead load
• B. Live load
• C. Impact load
• D. Lateral load

Answer: (A)

Permanent, non-variable loads on the roof are called dead load. This includes fixed components that add weight to the roof system, such as membranes, decking, framing, insulation, and other attached elements. These are part of the structure and don’t change with occupancy or weather. Live loads are the loads that can change over time, like people, stored items, or snow on the roof. Impact load refers to sudden forces from hail or falling objects, and lateral load is the horizontal force from wind or seismic activity. So the fixed, permanent roof weight is dead load.
