Cape Coral Roof design standards for non-residential and mixed-use buildings

This rule establishes roof design standards for non-residential and mixed-use buildings: roofs shall include features from at least two of the following five categories below.1.Parapet wall provided the parapet extends completely around the building on all sides. However, this requirement shall not prohibit the substitution of a pitched roof in lieu of a parapet for part of a building.2.A three-dimensional cornice treatment, a minimum of four inches high (not applicable along any portion of a wall that is built flush to the side lot line). Flashing at the top of a parapet shall not qualify as a cornice. Cornices shall return a minimum of eight feet around corners that transition from a building wall that requires a cornice to a building wall that does not require a cornice.3.Varied roof lines with different roof heights and or separate or distinct roof segments that fall at different horizontal planes above the cornice line;4.Overhanging eaves that extend at least 18 inches beyond the supporting walls, with a minimum fascia of six inches in height (not applicable along any portion of a wall that is built flush to the side lot line);5.Vertical variation in the roof line with a minimum change in elevation of two feet.B.Pitched roofs such as gable, hip, shed or mansard roofs shall be clad with highly durable materials such as standing seam metal, slate, ceramic, or fireproof composite tiles. Fiberglass and asphalt shingles are prohibited except for dimensional grade or better.1.Allowed slope. Pitched roofs shall have a minimum slope of three feet vertical rise for every 12 feet of horizontal run. The maximum slope of a pitched roof shall not exceed a one-foot vertical rise for every on foot of horizontal run.C.Roofs covering pavilions, carports, gas canopies, and similar structures with support posts or columns but no sides. Buildings with roofs that lack walls, whether free-standing or attached to another building, shall have a minimum slope of three feet vertical rise for every 12 feet of horizontal run. Unless a roof with an alternative design is approved by the DCD Director, all roofs are required to possess a pitched roof with a minimum slope of three feet vertical rise for every 12 feet of horizontal run. The DCD Director shall consider the following two criteria in determining whether to approve a roof with an alternative design:1.Whether the design of the roof evokes exceptional expression through the use of angularity, curvature, or other means; or2.Whether the design of the roof precludes visual monotony and enhances the aesthetic character. Flat and parapet roofs are prohibited for buildings covered by this subsection.
