ORDINANCE 2005- 017 with a slope less than 4:12 (rise:run) ("low sloped roof') shall not be visible from a roadway and/or residentially designated area. Low sloped roofs must be screened with a visible roof structure or parapet wall. 2. Visible roof structures: Visible roof structures shall be of such height, bulk, and mass, so as to appear structural, even where the design is non-structural, and shall have a minimum vertical rise of six (6) feet (not including facia). Visible roof structures shall have a slope no less than 4:12 (rise:run). Mansard style visible roof structures with a slope greater than 30:12 (rise:run) are prohibited. Where visible roof structures are utilized in a building design, they shall be continuous around all sides of the structure, except where incorporated with a parapet wall or other architectural element (this does not allow "stuck -on" roofs). Any facade that is not visible from a roadway, exclusive access drive, or residentially designated area, such as facades that are interior to a tightly spaced compound of buildings, will not require a continuous visible roof structure on that facade. Any building with less than three thousand five hundred (3,500) square feet of ground floor area shall have a visible roof structure on all facades. 3. The following roof styles are prohibited: "A frame," bowstring, dome, gambrel, non -symmetrical gable or hip (different slope on each side of ridge). Quonset, and Polynesian (gable or hip roof with up to a 1012 (rise:run) maximum pitch with a "skirted" or "flared" lower portion at a 3:12 (rise:run) minimum pitch is allowed). 4. The ridge or plane of a roof (or visible roof structure), that runs parallel (or slightly parallel) with a roadway shall not run continuous for more than one hundred (100) feet without offsetting or jogging (vertically or horizontally) the roof ridge or plane a minimum of sixteen (16) inches (see Figure B-2 in 911.19). Low slope roofs and parapet walls are excluded from this requirement. 5. Roofing on sloped roofs and visible roof structures shall be limited to the following systems: architectural standing seam metal, galvanized 5-V crimp, cedar shingles or shakes, slate, clay tile, or cement tile Architectural standing seam roofs shall be limited to the following systems: flat metal panels with narrow raised seams running twelve (12) to twenty (20) inches apart, which are secured with continuous seam covers or mechanically seamed. Light and natural colors, as well as mill finish metal roofs are encouraged. Mixing colors of metal panels is prohibited. 6. Roofing materials are prohibited for use as a finish material on parapets or any surface with a slope greater than 30:12 (rise:run), up to and including vertical surfaces. This pertains only to those surfaces visible from adjacent property, exclusive access drives or roadways. This does not exclude the use of metal facia six (6) inches or less in height, use of typical metal flashing, wall cap, drip edge, and the like, use of roofing materials as a screening device (as long as it does not function as a building's parapet), and use of cedar shingles or shakes as a wall material used below the roof line.
