HDLC Guidelines:

Section 5, Page 5 of the Guidelines for Roofing state that Metal Roofs were popularized after sheet metal production was expanded following the mid 19th century, and can be found on commercial and industrial buildings, as well as residences and outbuildings. Traditional sheet roofing metals include lead, copper, zinc, tin plate, tern plate and galvanized iron. Many metal roofs require regular painting with traditional colors including silver, grey or green to minimize the potential for corrosion. On shallow pitch roofs like galleries, porches, cupolas or domes, small rectangular pieces of flat seam metal roofing were installed with edges crimped together and soldered to form a weather-tight surface. On steeper pitched roofs, long continuous seams were used, typically in a standing seam configuration, providing regular ridges down roof slopes. Corrugated or other paneled metal roofing was also common on commercial and industrial buildings as well as outbuildings, such as sheds and garages. Metal roofs are typically not appropriate for highly visible roof slopes or where the original roofing material would have been slate, especially on higher style buildings. Metal roofs may be considered for installation where minimally visible.

Staff Recommendation:

• Standing Seam Metal Roof: No recommendation.

Staff Recommendations:

The applicant is requesting to remove the existing asphalt shingle roof for installation of new standing seam metal roofing in a galvalume finish. Based on FEMA survey research, the Greek Revival style American townhouse type building appears to have been constructed sometime between 1870 to 1880. The building is 2-stories tall and has reduced visibility of the existing hipped roof from the public right of way due to the building height, the low pitch of the roof, existing street vegetation, and due to an atypical parapet extension that runs from the façade to the rear of the building on the right side. The building likely originally had a slate roof based on its age and a previous CofA which indicated roof ridge tiles were extant around 1980. These ridge tiles have since been removed and are now considered a permitted non-conformity. As per the HDLC Guidelines, metal roofs are typically not appropriate for highly visible roof slopes or where the original roof material would have bene slate, especially on higher style buildings. Based on these factors, Staff has no recommendation and leaves approval for the request at the discretion of the Commission. However, if approval is granted, Staff recommends a proviso that the metal roofing be specified in a dark color and with a less reflective finish.
