PAC-CLAD Metal Roof Products Receive ICC-ES Code Compliance Verification

Four of Petersen’s PAC-CLAD metal standing seam roof systems are included in a new ICC Evaluation Service report. The ICC-ES Evaluation Report ESR-4173 provides independent verification that Snap-Clad, Tite-Loc, Tite-Loc Plus and PAC-150 180-degree double-lock standing seam roof panels meet the fire classification and wind uplift resistance requirements of the International Building Code, International Residential Code, California Building Code and California Residential Code.

ICC-ES Evaluation Reports are used by building officials, architects and contractors as a basis for specifying or approving PAC-CLAD metal standing seam roof systems in construction projects that conform to the IBC, IRC, CBC and CRC. The report proves that ICC-ES thoroughly examined Petersen’s PAC-CLAD roof panels to ensure the products are code-compliant.

“The ICC-ES report provides specifiers, architects and contractors with a broader scope of projects they can specify or bid utilizing Petersen’s PAC-CLAD standing seam roof panels,” said Josh Jacobi, national manager, technical services for Petersen. “With the opening of the PAC-CLAD facility in Phoenix and our desire to increase our presence in the Western United States, the ICC-ES Evaluation Report is critical to securing architectural specification of our roof panels in California and other Western states. Without this report, the amount of projects we could pursue is dramatically reduced, which would have placed limitations on our growth in this region of the United States.”

An ICC-ES Evaluation Report provides information about which code requirements or acceptance criteria were used to evaluate the product, how the product should be installed to meet the requirements, how to identify the product, and more. The reports are intended to safeguard the built environment and make the building official’s job easier when approving products for installation.

ICC-ES evaluates building products per various code requirements through ICC-ES Acceptance Criteria and code-referenced consensus standards. Evaluations address performance characteristics such as structural, seismic and fire resistance. Holding an ICC-ES Evaluation Report proves a manufacturer’s building product or system has undergone a rigorous technical and manufacturing quality evaluation conducted by ICC-ES staff. The ICC Evaluation Service is a member of the ICC family of companies and is a nonprofit, limited liability company.

Petersen manufactures PAC-CLAD architectural metal cladding products in multiple gauges of steel and aluminum. PAC-CLAD products include standing seam roof panels, hidden- and exposed-fastener wall panels, flush- and reveal-joint panels, vented or solid soffit panels, perforated metal, coil and flat sheet, composite panels, column covers, plus fascia and coping. All are available in Kynar 70 percent PVDF finish in 45 standard colors that include a 30-year finish warranty. Most colors meet LEED and Energy Star requirements, and are rated by the Cool Roof Rating Council. Custom colors and weather-tightness warranties are offered.

Challenges With Metal Roof, Manpower Overcome at Alabama School

At Indian Springs School in Birmingham, Alabama, the first phase of a three-phase construction plan included building three new classroom buildings and a new administration building, as well as re-roofing the library. The roofing portion of the project included 45,000 square feet of 18-inch-wide, 24-gauge PAC-CLAD roof panels manufactured by Petersen. Photos: Petersen

When founded in 1952, the master plan for Indian Springs School in Birmingham, Alabama, called for campus development to maintain focus on the lake at the center of the school’s wooded 350-acre property. During the past 30 years, however, focus was lost, so a new plan was made to demolish some existing structures and construct buildings that re-establish a connection to the lake. The school enrolls 280 students in grades 8-12.

Phase one of a three-phase construction plan consisted of constructing three new cypress-clad, single-story classroom buildings and a new administration building, plus a re-roof of an existing library building. Oversight of design and construction was handled through a partnership of Lake Flato Architects in San Antonio and ArchitectureWorks in Birmingham. The first phase utilized 45,000 square feet of Petersen’s 18-inch-wide, 24-gauge Snap-Clad and Tite-Loc roof panels in Cool Color Zinc. The new buildings, which added 18 classrooms and 18 administrative offices, achieved LEED Silver status.

Installation of the PAC-CLAD roof was completed by Quality Architectural Metal and Roofing in Birmingham. The combination of panels was determined by the roof pitch, according to Eddie Still, the company’s vice president and project manager. “We used the mechanically seamed Tite-Loc panel on a few areas with pitches that required that profile, which amounted to less than 2,000 square feet,” he notes.

Some of the buildings feature monitors, which provide daylighting to each classroom, onto which QAMR installed PAC-CLAD flush panels for both the vertical and horizontal sections. This was a big job, Still notes. “Installation went smoothly, but finding manpower to get it done was the problem,” he says. “The job was big with multiple buildings, and I wasn’t able to stop all of our other projects for this one job. So, we approached it like four small jobs. This sounded good in theory, but there were delays with the work in front of us which impacted my schedule. This meant I had to put two crews out there to catch up. And then I had to call one of my friendly competitors and put one of his crews out there to help out. I’ve never done that before, but it worked out. Plus, these architects were good to work with. We had no issues at all on this project. We worked smoothly together.”

Still notes he frequently uses Petersen’s Snap-Clad panel. “The panel performs well and we’ve never had problems with it,” he says. “You don’t need to reinvent the wheel; you just need a product you can depend on. We have a 30-plus year relationship with Petersen and they’re great to do business with.”

ArchitectureWorks, which was first to join the project and managed the construction portion, formed a partnership with Lake Flato because of its focus on school design. “In general terms, Lake Flato was the design architect doing the master planning, and ArchitectureWorks was the architect of record, or executive architect, that completed construction documents and oversaw the construction phase,” says Greg Papay, FAIA and partner at Lake Flato. “We get asked to team up on jobs all the time, but they don’t all go as smoothly as this one did. ArchitectureWorks was great to work with.”

The design team sought to respect the school’s original structures’ simple forms and materials while opening the new buildings to nature. “Our notion was that 21st century schools could actually feel more like 19th century schools,” Papay explains, referring to the firm’s back-to-basics approach.

Focus on the Roof

All new buildings feature a roof that extends over covered walkways. “The roof shape allowed us to create transition spaces around each building that blur the lines between indoor and outdoor areas,” Papay says. “We chose a metal roof for longevity, attractiveness and efficiency properties. Plus, Birmingham used to be the steel capital of the South, so to have it on the buildings was a subtle reference to that local history.”

The school’s Southern U.S. location was also taken into account, notes Papay. “It was important to find balance between heat gain and glare inside from reflectivity off a neighboring roof, so we had to find the right color that addressed those issues,” he says “In the end we chose PAC-CLAD’s Cool Color Zinc.”

Lake Flato’s approach to building materials is to allow each to express its nature, where steel and wood in this application remain light in appearance. “We want a metal roof to look thin at the edge, so we don’t use heavy fascia. Some people wrap roof edges with fascia and don’t care if its appearance is thick or heavy, but fascia is not part of our approach; we were mindful of the details,” Papay says.

Papay points out that these buildings have subtle geometry shifts to accommodate natural rock groupings on the land. Therefore, he notes, “there was some roof detailing required where it was not turning at 90 degrees with a simple ridge/valley, so there was some metalworking trickery required at that point. Also, we created roof monitors which are smaller elements that required refined metal work. The roof looks great thanks to a great installation job.”
