1 CITY HISTORIC ZONING COMMISSION STAFF REPORT - CERTIFICATE OF APPROPRIATENESS APPLICATION MEETING DATE: 10/18/2012 FILE NO.: ONK APPLICANT: Lawrence Eaton (under contract to purchase) ADDRESS OF PROPERTY: 700 E Scott Ave HISTORIC DISTRICT: Old North Knoxville H-1 TYPE OF WORK: DESCRIPTION OF WORK: PROPERTY DESCRIPTION: Level II. Replacement/repair Replace original French cement tile roof with 30-year dimensional asphalt shingles. Craftsman (Pell House) (1914) One-story frame with wood shingle wall covering. Side gable roof with French cement tile covering, knee braces, and rafters. Double-hung three-over-one windows. One-story one-bay front-gabled porch with truncated brick columns flanked by one-bay unroofed porch with truncated brick piers. Lattice patterned sidlelights and transom at front entry door. Exterior end brick chimney. Brick foundation and retangular plan. APPLICABLE DESIGN GUIDELINES: Old North Knoxville Design Guidelines, adopted by the Knoxville City Council on November 25, STAFF RECOMMENDATION: APPROVAL to replace/repair rotted wood trim and details to exact specifications of original, remove carport structure, replace gutters, tuckpoint masonry, replace roof tile with 30-year dimensional asphalt shingles to match existing closely in color. COMMENTS: Recommendations for conditions of approval are: 1) that the roof crests at the peak of the front and side gables be reinstalled or retained and stored and 2) that the replacement asphalt shingle match the existing cement tile color as closely as possible. The applicant has offered to retain a sampling of the original roofing material with the house, and donate the remainder of reusable material to Knox Heritage. Staff supports these actions. STAFF FINDINGS: 1) The French cement tile roof is a character-defining feature as indicated by the description in the 1996 survey file. The roof has a unique profile, pattern, and prominent texture. 2) The appearance of the tile coping at the roof ridges will not be retained as the proposal includes adding ridge vents. The applicant is researching the ability to retain the crests at the peak of the roof gables. 3) The examples of this type of roof are dwindling. This is because many of the original slate, tile, and metal roofs dating from th first half of the 20th century have reached the end of their serviceable life. 4) Cement roofing tiles are readily available, but like slate roof tiles, research and quotes provided by the applicant indicate that they are prohibitively expensive. 5) The close-up photos of the roof and contractor's evaluation indicate that portions (including the front) of the roof exhibit plant material growth and are cracked, broken and chipped. 6) It is possible that a future owner could choose to replace the French cement tiles in order to recreate the original roof appearance since the essential historic form of the roof structure will not be changed.

2 DESIGN GUIDELINES: A. ROOFS 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 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. 3. Repair or replace roof details (chimneys, roof cresting, finials, attic vent windows, molding, bargeboards and other unique roof features). Use some of these details in designing new buildings. 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 appropriate, 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. 7. Gutters shall be half-round if they are replacing half-round gutters... E. WALLCOVERINGS 3. Replacement siding must duplicate the original. Trim and patterned shingles that must be replaced must also duplicate the original material. 4. New construction must incorporate corner and trim boards and appropriate door and window trim to be compatible with adjacent historic buildings. 5. Wooden features shall be repaired by patching, piecing-in, or otherwise reinforcing the wood. Repair may also include limited replacement with matching or compatible substitute materials, when elements remain and can be copied. 6. Wood features that are important in defining the overall historic character of the building shall not be removed. 7. Replace only deteriorated wood. Reconstructing in order to achieve a uniform or "mproved," "new" appearance is inappropriate because of the loss of good historic materials. 8. An entire wooden feature that is too deteriorated to repair or is completely missing shall be replaced in kind. If features are replaced, the materials they are made from shall be compatible with the original in size, scale and material. Replacement parts should be based on historical, pictorial and physical documentation. SECRETARY OF INTERIORS STANDARDS: 5. Distinctive features, finishes and construction techniques or examples of craftsmanship that characterize a property shall be preserved. 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 design, color, texture, and other visual qualities and, where possible, materials. Replacement or missing features shall be substantiated by documentary, physical or pictorial evidence.
