(a) Every roof sign, including the upright supports and braces thereof, shall be constructed entirely of non-inflammable materials, but combustible structural trim may be used thereon.
(b) No roof sign shall have a surface or facing exceeding 500 square feet, except that in the case of off-premises signs the maximum limit shall be 672 square feet, or have its highest point extended more than twenty-five feet above the roof level.
(c) No roof sign shall be erected or maintained with the face thereof nearer than five feet to the outside wall toward which the sign faces.
(d) All roof signs shall have a space at least five feet in height between the base of the sign and the roof level, and have at least five feet clearance between the vertical supports thereof.
(e) No roof sign shall be placed in such a manner as to prevent free passage from one part of the roof to any other part or interfere with openings in the roof.
(f) Every roof sign shall be thoroughly secured to the building by iron or other metal anchors, bolts, supports, rods or braces. When erected upon buildings which are not constructed entirely of fireproof material, the bearing plates of the sign shall rest directly upon masonry walls and intermediate steel columns in the building. No roof sign shall be supported or anchored to the wooden framework of a building.
