Quality Control and Quality-assurance Guidelines for the Application of Membrane Roof Systems presents NRCA's on-site evaluation guidelines during the application of membrane roof systems.
The publication stresses the importance of thorough, continual inspections during roof system construction to recognize and correct variances as they are detected and provides guidelines to appraise the quality of application. Where appropriate, the guidelines describe expected variances in application parameters related to vapor retarders, insulations, fasteners, membranes, flashings and surfacings.
