(C) (1) Every rain leader located without the walls of a building shall be substantially constructed of galvanized sheet iron, sheet copper or other suitable material, and shall be thoroughly supported in place. Rain leaders run within a building shall be considered a downspout and shall be constructed in accordance with the requirements of this chapter. Short connections to rain leader pipes passing through attic or other parts of buildings shall be considered a downspout and shall be constructed of lead pipe or extra heavy cast iron pipe or galvanized wrought-iron pipe with recessed fittings. No gutter or rain leader shall be of less size than the following.
