Which option accurately describes the width of ice dam protection for a 6:12 roof with 30 horizontal inches eaves?

  1. A 40 horizontal inches

  2. B 50 horizontal inches

  3. C 54 horizontal inches

  4. D 64 horizontal inches

The correct answer is: C 54 horizontal inches

For a 6:12 roof with 30 horizontal inches of eaves, the correct width of ice dam protection would be 54 horizontal inches. The width of the ice dam protection should typically extend from the eaves to a point at least 24 inches inside the exterior wall line of the building. This is to prevent ice dams from forming and causing water damage to the roof structure and interior of the building. Therefore, a width of 54 horizontal inches would provide adequate protection for a 6:12 roof with 30 horizontal inches of eaves.
