Roof signs are divided into the two main categories shown in Figures 14 and 15 and described in (A) and (B) below.
(A) Roof signs on buildings which do not exceed 40 feet in height and which are designed for viewing by traffic passing by the sign installation. (Figure 14).
TABLE 2A
Division (A), roof signs on buildings which do not exceed 40 feet in height with a sign designed for adjacent traffic and are limited to two faces.

Nonfreeway
15 - 20 100 square feet 300 square feet
25 - 30 150 square feet 300 square feet
35 - 40 200 square feet 300 square feet
50 250 square feet 300 square feet
Freeway-oriented, 300 square feet 720 square feet
where supporting building is in
a zone permitting roof signs.
NOTE: As these sign regulations require that roof signs appear as an architectural blade with no visible structure, line of sight will reduce effective useable area as building height increases (See Table 2B). Area allowances, therefore, include that which would have been seen as structural support in most former sign regulations.

NOTE: As these sign regulations require that roof signs appear as an architectural blade with no visible structure, line of sight will reduce effective useable sign height as building height increases. Height allowances, therefore, include that which would have been seen as structural support in most former sign regulations.
(B) Roof signs on multi-storied buildings designed to be viewed from distant points.
(1) This chapter commits these signs to the same configuration as an architectural blade or penthouse which could have occurred as part of the building itself. Such signs, therefore, are treated as would be facia signs in division (A) as wall signs applied to an existing penthouse. (Figure 15).
(2) In zones where roof signs are permitted, such signs must be manufactured in such a way that they appear as an architectural blade or penthouse and are finished in such a manner that the visual appearance from all sides is such that they appear to be a part of the building itself. (Figures 15 and 17).
(3) All roof signs shall be installed or erected in such a manner that there shall be no visible angle iron support structure. (Figure 16).
(4) All roof signs must be set back a distance of at least four feet from all the outside walls of the building on or over which they are located. It is the intention of this provision to provide a clear passageway around the sign.
(5) Roof signs may not rotate.
(6) For residential proximity regulations set forth in § 157.040 (E) shall apply.
(7) No visible guy wires, braces, or secondary supports are to be used. See Figure 17 for permissible method.
