The Sevierville Community Center is aptly named. Residents of the Tennessee town take full advantage of its comprehensive recreational offerings, including a bowling center, gymnasium, fitness center, Olympic-sized natatorium, cycling area, racquetball court, and meeting rooms.
So, when the roof started leaking in several places, closing the center to tear off and replace the failing roof was not an option.
Installing a new metal roofing system over an old 610-mm (24-in.) trapezoidal metal roofing panel requires sub-purlins to create a new structural framing system. Roof Hugger provided 114-mm (4.5.-in.) tall Roof Hugger notched zee sub-purlins for most roof areas. However, in the corners where purlin spacing needed to be reduced for code compliance, 86-mm (3.375-in.) tall sub-rafter hats were run upslope over the existing purlins and overlayed with 29-mm (1.125-in.) tall hat sub-purlins, providing the correct reinforcement for the attachment of the new roofing panels. All necessary fasteners were included.
Morristown Roofing of Whitesburg, N.C., handled the installation of Roof Hugger sub-purlins as well as the MRS 24-gauge 2500, 406-mm (16-in.) wide vertical rib-painted structural panels from Metal Roofing Systems of Stanley, N.C. The roof covers approximately 4,645 m2 (50,000 sf) with pitches of 4:12 and 5:12. Sub-purlins were installed approximately 1.5 m (5 ft) apart, with the space created by the sub-purlins between the original roofing panels and the new panels filled with insulation to improve R-value. The new system meets standards for winds of 75 km/h (120 mph) and features the color of Mansard Brown.
Ashley Horner, VP of Morristown Roofing, says the building’s irregular shape meant installing the sub-purlins, and the roofing was challenging in some aspects.
“The intricate details and the high visibility of the roof area required the detailing be both precise and aesthetically pleasing as the fifth wall of the structure,” Horner says. “The biggest challenge was the protection of the public, as the community center is a vital resource for the community throughout the day. By working together as a team and adapting to the changing circumstances, we were able to successfully address the challenges and provide a finished product we are proud to be associated with.”
