Historic Zoning Commission
Old North Knoxville H: Level II
1-F-21-HZ
Staff Recommendation
Staff recommends approval of the roof's replacement. All efforts should be taken to replace with new slate roofing instead of architectural shingles. Recognizing the cost-prohibitive nature of new slate materials, the Commission may choose to approve the submitted architectural shingles. If the architectural shingles are approved as a replacement material, the new roof should incorporate any roof details, eave overhangs, and not modify the unique pitch and shape of the roof's design.

Roofs
Historic Characteristics: the roofs in Old North Knoxville are now nearly all modern asphalt shingles. There were a variety of original roofing materials, such as standing seam metal or metal shingles, wood or slate shingles, large patterned asphalt or asbestos shingles, or shaped roof tiles of terra cotta or concrete. The historic roof colors would have been darker shades of brown, grey, red, green, or black. [...] The best roof materials to use when roofing are replicas of the original. If that cannot be done, asphalt or fiberglass shingles can be used, but their colors should be carefully selected to reflect the original roofing colors.
1. The shape of replacement roofs shall imitate the shapes of roofs on neighboring existing houses or other houses of the same architectural style.
3. Repair or replace roof details (chimneys, roof cresting, finials, attic vent windows, etc).
4. Materials used in roofing existing buildings or new construction shall duplicate the roofing materials originally found in the neighborhood. Asphalt or fiberglass shingles can be appropritae, as are wood, slate, standing seam metal, or metal shingle or tile roof coverings. The color of roofing materials should be a dark green, charcoal gray, black, or dark reddish brown to simulate the original roof colors.
6. Roofs that are visible from streets shall retain their original shapes.
SOI Standards for Rehabilitation
6. Deteriorated historic features shall be repaired rather than replaced. Where the severity of deterioration requires replacement of a distinctive feature, the new feature shall match the old in design, color, texture, and other visual qualities and where possible, materials. Replacement or missing features shall be substantiated by documentary, physical, or pictorial evidence.
