Competitors will install the most commonly used roof type, thermoplastic, on the same mockup used for NRCA’s ProCertification exam. Participants will put on all required safety equipment, roll out a sheet of thermoplastic membrane, mechanically attach it to the deck, flash the perimeter edge wall, and flash around a box and pipe boot. Contest involves a written test, which is the same as the exam for NRCA’s TRAC: Thermoplastic course.
