Minimum flat roof overhang. Minimum roof fire resistance ratings apply based on the type of construction and some building types do not require a fire rating. Eave overhangs shall not exceed 24 inches 610 mm measured horizontally. Some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto underlying wood.
