holyinnocents1Originally located in what is now downtown 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 developed and expanded to almost 35 acres.

Much of the church compound, including the original vintage church nave, church offices, 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, offices, 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 standing seam panels and 1-mm VMZ flat lock panel in QUARTZ-ZINC from Umicore Building Products USA Inc., Raleigh, N.C.

holyinnocents2“We decided to use zinc metal roofing because it fit well with the original design of the sanctuary, which was designed with large lapping panels or bands of roofing 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 weathering and permanence that seemed to be a good fit with the church, which conveys a message of truth and permanence to believers.”

The flat lock panels successfully mitigate water 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 protective 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 reflectance to accentuate the roof forms’ strong architectural lines.

holyinnocents4Additionally, Balke notes that zinc weathers well, develops a “healing patina” and is not ostentatious. “From a practical standpoint it will outlive five asphalt roofs and is therefore environmentally friendly,” he adds. “The natural color of the zinc panel was also a good honest fit 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 first time this particular team had worked with zinc roof. “Coordinating tie-in details to other roofing materials and the structure below was challenging,” he says. “We utilized BIM details to ensure all waterproofing was designed and installed correctly prior to the actual install.”

The zinc roofing was combined with two types of high-performance glass, one of which offered more shading for the sun-exposed façades, and the other that allowed as much light transmittance and visibility in and out as possible. The more light-transmitting glass is used at the new chapel and north-facing office spaces, while the more light-screening glass is used at the gallery spaces and façade.
