Rooflines should mimic the separate yet complementary rhythm of historic Mainstreet buildings.
Flat roofs (slightly sloped to drain) are preferred with parapets that articulate the rhythm of the buildings. Parapets should be embellished with brick detailing and stepped or sloped to achieve a visually interesting yet harmonious sequence along the building façade.
Sloped roofs are not allowed unless the roof form is concealed by a parapet or false front. Exceptions may be granted if the sloped roof is used on top of a multi-story building to help reduce the overall height of the façade and define the residential character of the upper floors.
