New zinc roof modernizes and complements church
Originally located in what is now down- town Atlanta, Holy Innocents Episcopal Church, moved to the suburbs in 1954. As the parish grew, the need for more space became apparent. Over time, the school de- veloped and expanded to almost 35 acres. Much of the church compound, including
the original vintage church nave, church offi ces, multipurpose parish hall, youth ministry building and choir rehearsal room, along with the elementary, middle and high school, had aged beyond its useful life. A revitalized church compound was desired to meet the growing needs, activities and outreach ministries, as well as to attract young members and families. Parish leaders decided the best way to update the church was to renovate the nave and build new structures on the campus. In Spring 2011, the church underwent major renovations and now includes more than 30,000 square feet of worship spaces, offi ces, meeting rooms and event facilities. Designed by TVS Associates, Atlanta, the
37,590-square-foot project was completed in September 2012. The project consists of 30,400 square feet of new construction and a 7,190-square-foot renovation. Replacing asphalt shingles for the roof for the church nave, the project features 12,500 square feet of VMZ stand- ing seam panels and 1-mm VMZ fl at lock panel in QUARTZ-ZINC from Umicore Building Products USA Inc., Raleigh, N.C. “We decided to use zinc metal roofi ng because
it fi t well with the original design of the sanctuary, which was designed with large lapping panels or bands of roofi ng reminiscent of some of the works of Frank Lloyd Wright,” notes Robert Balke, project studio director at TVS. “Moreover the choice of zinc conveyed a sense of authenticity, strength in weath- ering and permanence that seemed to be a good fi t
with the church, which conveys a message of truth and permanence to believers.” The fl at lock panels successfully mitigate wa-
ter intrusion for the nave. Zinc gutters were formed with razor-sharp precision using masked stainless steel clips to create a crisp detail. Because of its genuine natural properties of developing a protec- tive patina, coupled with its cost effectiveness and durability, zinc was an ideal metal choice for the project. Using zinc for the chapel’s roof, along with a panel system, allowed for the roof material, joint lines and uniform surface refl ectance to accentuate the roof forms’ strong architectural lines. Additionally, Balke notes that zinc weathers well,
develops a “healing patina” and is not ostentatious. “From a practical standpoint it will outlive fi ve asphalt roofs and is therefore environmentally friendly,” he adds. “The natural color of the zinc panel was also a good honest fi t with the native granite used for walls in the new designs, as well as a nice counterpoint to natural wood used in the design.” Brad Stolz, project manager with the general
contractor, JE Dunn, Atlanta, notes that this project was the fi rst time this particular team had worked with a zinc roof. “Coordinating tie-in details to other roofi ng materials and the structure below was chal- lenging,” he says. “We utilized BIM details to en- sure all waterproofi ng was designed and installed correctly prior to the actual install.” The zinc roofi ng was combined with two
types of high-performance glass, one of which of- fered more shading for the sun-exposed façades, and the other that allowed as much light transmit- tance and visibility in and out as possible. The more light-transmitting glass is used at the new chapel and north-facing offi ce spaces, while the more light-screening glass is used at the gallery spaces and façade.
