A vent pipe that penetrates the roof in an area without significant snowfall must extend at least how far above the finished roof surface?
a.1 inch
b.2 inches
c.4 inches
d.6 inches
Giải thích
The code generally requires vents to terminate at least 6 inches above the roof so debris and water do not block the opening. The smaller heights would leave the vent too close to the roofing to function reliably.
