Wilmington Design Standards for Historic Districts and Landmarks

6 5 4 3 2 1 Standards for Building Changes 57 7 The variety of Wilmington’s roofs re fl ects the diversity of its architecture. Every type of roof from the simple gable to the complex mansard including hipped, gambrel and fl at roofs are found within the historic districts. Hipped roofs are the most common because of their adaptability to the popular Italianate style. Complex roofs including turrets , intersecting planes and a variety of gables associated with the late 19 th-century Queen Anne style also occur within the historic districts. Most of the vernacular cottages have street or side facing gable roofs. The pitch of the roof and size of the overhang are in fl uencedbythebuildingstyle. Chimneys, dormers , turrets, cresting , cupolas , belvederes , fi nials , and other roof features re fl ect the style and character of the building. Wood shingles were used in Wilmington for domestic buildings until advances in technology made possible a variety of other roo fi ng materials such as standing seam metal, polychrome slate, and clay tiles. Standing seam metal became the accepted roo fi ng material in Wilmington about 1870 and provided a consistency to the streetscape. Although slate, clay tile, and asbestos shingle roofs can be found within the residential areas of the historic districts, they are more common on the Revival and Eclectic-style houses of the Carolina Heights/Winoca Terrace District. Suggested Repair and Maintenance Frequent inspection and prompt repair are important for the preservation of historic roofs. Paint metal roofs to avoid corrosion. Incompatible fl ashing materials and fasteners can cause galvanic corrosion and should be avoided as should coating the roof with tar or aluminum paint. Well maintained metal roofs have a life expectancy of at least 100 years. The nails and fl ashing used to attach slate and clay tile roofs can fail but this is repairable. New hangers can be installed to hold up individual slates or tiles. Asphalt and fi berglass shingles are commonly used for newer buildings. The entire roo fi ng system which includes gutters, fascias , downspouts , fl ashing and coping requires frequent inspection and prompt repair. Clean gutters and downspouts on a regular basis to remove leaves and other debris. Built-in gutters, which contribute to the character of many older residences, are important to retain and should be frequently inspected to prevent water seepage into the walls of the building and possible damage to the cornice . If another roof is installed above the built-in gutter, the procedure should be reversible, allowing for repair of the gutter at a later date. Roof and sof fi t vents should be inspected from time to time to ensure they are unblocked. Flashing around chimneys and valley fl ashing must be maintained and replaced as necessary. The use of copper, galvanized metal, or rolled aluminum with a baked enamel fi nish is preferred to the modern roo fi ng practice of weaving asphalt shingle s to create valley fl ashing.
