Giải thích
A vent through a roof used only for weather protection must extend at least 6 in above the roof. The 12 in dimension applies where the roof is used for any purpose other than weather protection, such as a deck or assembly area, and 3 in is below the minimum while 24 in exceeds what the code requires here.
