What is the minimum height a fire wall must extend above adjacent roofs?

The minimum height that a fire wall must extend above adjacent roofs is 30 inches. This requirement ensures that the fire wall provides adequate protection and helps prevent fire spread between structures or sections of a building. The specified height is designed to minimize the risk of flames or heat transferring to adjoining roofs, especially in cases of fire.

This height standard is influenced by the need for the fire wall to act as a barrier, ensuring that it maintains its effectiveness during fire exposure. If the wall were to extend less than this minimum height, it may not provide sufficient isolation for adjoining structures, failing to serve its intended purpose during emergency situations.

In practice, adhering to this standard is crucial for maintaining fire safety codes and making sure that buildings can withstand the spread of fire effectively, contributing to overall safety for occupants and emergency responders.
