In HVHZ, lead flashing shall not be less than how many inches?

Explanation:
In HVHZ, the amount of lead flashing used must be wide enough to form a dependable seal and withstand high wind forces. The minimum width of lead flashing is 2.5 inches because this provides enough material to create proper laps and to be effectively overlapped by counterflashing, reducing the risk of wind-driven water penetration and uplift at roof-to-wall joints and around penetrations. Using less than this increases the chance of tearing or peeling under high wind loads, while a width of 2.5 inches meets the code requirement as the recognized minimum.
