Middle School Makes Roof Right

CHALLENGE:Installed in 2004, the standing seam metal roof at the Wright City Middle School, Wright City, Mo., was comprised of eight roof areas of various elevations with a 4/12 pitch and decorative dormers. By 2014, something had to be done about the failing roof system, but, due to time constraints and the environmental cost of demolition and disposal, tearing off the existing roof was not an option. INFLUENCE:Building aesthetics, proper insulation and waterproofing were top of mind on the Wright City Middle School roofing retrofit. SOLUTION:

The Wright City school board, superintendent, and director of maintenance decided to re-cover the existing roof with a Carlisle SynTec Systems’ FleeceBACK KEE HP PVC adhered roofing system with Contour Rib Profiles. To replicate the appearance of the existing metal roof, installing contractor Missouri Builders Service hot-air welded Carlisle’s Sure-Flex PVC Contour Rib Profile to the membrane’s surface in a parallel pattern. Manufactured from the same weather-resistant compound as Carlisle’s Sure-Flex PVC, Contour Rib provides the aesthetic appeal of a standing seam metal roof at a lower cost than conventional metal roofing. The product is dimensionally stabilized and strengthened by a 1/8-in. fiberglass reinforcing cord that runs the length of each 10-ft.-long section, and its non-penetrating application has no effect on the roof’s watertight integrity. Wright City Middle School chose the system for a number of reasons. FleeceBACK KEE HP PVC membrane is heat-weldable, allowing for reduced construction time and reduced noise during installation. The product offers high wind uplift performance, excellent fire resistance, and meets Energy Star qualification guidelines. Flexible FAST Adhesive boasts exceptional thermal efficiency, with each layer adding R-value, thereby dramatically improving insulation.
