Three-Tier Metal Roof Disguises Mass Of New Oklahoma School

WEB-Heritage_Elementary_4451The expansive new 500-student pre-K thru 4th grade Heritage Elementary School in Tahlequah, Oklahoma, was greatly needed by its growing community. The project, designed by Crafton Tull in Tulsa, features a curving spine element that provides the main circulation corridor off of which three major classroom “fingers” radiate.

A defining entry area of the 70,000-square-foot structure honors Tahlequah’s Cherokee Indian history with a representation of the Cherokee sacred fire, a symbol of the culture’s unity and strength. Enrollment at Tahlequah Public Schools includes approximately 44 percent Native American students.

Nearly 87,000 square feet of Petersen’s PAC-CLAD Galvalume Snap-Clad panels in 24 gauge steel were selected to roof the sprawling structure. The innovative roof design on each classroom wing features three different levels that minimize mass and offer a sleek look. The Snap-Clad panel profile was specified as an option by the architect, said Jason Irvin, branch manager of Harness Roofing in Tulsa, the installing contractor.

But other than that, the job was relatively straight-forward. There was just a lot of it!”

Many of the Snap-Clad panels were up to 60-feet long and were fabricated on-site using Petersen’s portable roll-forming equipment provided from its Tyler, Texas, plant. “The longer panels were lifted onto the roof using a crane and spreader bar,” Irvin said. “The shorter panels were manufactured in Tyler, crated and shipped to us.”

Long-recognized for its metal standing seam roofing products, Petersen also offers metal wall panels including exposed fastener panels, flush panels, composite wall panels, fascia and coping systems, and column covers. All provide the well-known Petersen quality and are available in PAC-CLAD full 70 percent PVDF finish in 38 standard colors on steel and 37 on aluminum. Most colors meet LEED, Energy Star and Cool Roof Rating Council certification requirements.
