Where an ice barrier is required, it must extend from the eave edge to a point at least how far inside the exterior wall line of the building?
a.24 inches
b.12 inches
c.6 inches
d.36 inches

The ice barrier must reach at least 24 inches inside the interior face of the exterior wall so that ice damming at the eave cannot force water under the roofing into the building. 12 and 6 inches are too short, and 36 inches exceeds the minimum.
