STAFF REPORT CONCERNING APPLICATION FOR A CERTIFICATE OF APPROPRIATENESS Date: 03 July 2013 Application Number: 2013-0620 Property Location: 801 Park Avenue Architectural Style/Date/Architect or Builder: Gabled-ell/1885 Property Owner: Paula Rast Harris Landmark or District Designation: Chapin Park Local Historic District/Chapin Park National Register District Rating: Notable DESCRIPTION OF STRUCTURE/ SITE: Two storey irregular plan, documented as a Gabled -ell in the 2005 survey, a Stick Style on 1977 survey card and as a Late Gothic Revival on the 1987 survey card. There are many intersecting gables of the roofline and although each survey card, including the 1932/49 Assessor's card notes asphalt shingles, the gabled roof material is actually asbestos tile. The roofline employs a rake decorated fanciful non-structural barge board with pendills, the wide plain frieze, and brackets. A low hip roof entry porch on the east side has a dentilled frieze board and square fluted supports. There are 1/1 wood double hung windows with wood sill. A gable garage with vertical plank siding is accessible from Manitou. ALTERATIONS: No previous COAs were recorded in the file. Although the existing roof is asbestos tile, asphalt roof ,vas named on the 1977 and 1987 survey cards and on the 19332/49 Assessor's card. APPLICATION ITEMS: Tear off and re -roof home with asphalt shingles. DESCRIPTION OF PROPOSED PROJECT: Owner has applied to replace the asbestos sections of the roof with new asphalt architectural shingles. Work would include removing all layers and other roof material, re -decking, installing drip edge, re -flash chimney, install ice and water shield, felt paper, architectural shingles ridge cap shingles, can and ridge vent, and plumbing boots. A contractor has not been selected at time of Staff Report and we do not have information as to disposing of asbestos. From viewing photographs taken of the roof, the asbestos material seems to be in rough shape, including build up of organic material, chipping/brittle shingles, shingles replaced with another roofing material (possibly slate), missing vent caps and deteriorating or insufficient flashing. Wood rot is also a problem on some of the comer trim. Extracted from a Roof Report by Slatile: I. Existing Conditions of Sloped Roof Areas: 1. The roof consists of multiple sections of 12/12 pitch gable roofs. Decking is -wood, open slat design. Base roofing material is cedar shake. Second layer material is asbestos tile. a. The asbestos tiles are past the serviceable life of the material. The tile are severely pitted and worn. There is a buildup of moss and algae on the slates, further depredating the integrity of the slates. The current roof is far past its life and requires replacement. Replacement must include removing the cedar shakes under the current slates. The serviceable life of the over-all roofing on this house is less than 7 years before significant water infiltration is noticed. Regular maintenance and repair could, however, extend the life of the roof slightly.
