Abstract	Field observations have identified that air intrusion in mechanically attached roof systems can affect roof system performance. However, the question of how much air movement occurs and which components provide the required resistance to air movement has never been addressed.To measure air intrusion in mechanically attached roof systems, an experimental study has begun at the National Research Council (NRC) of Canada as part of its Special Interest Group for Dynamic Evaluation of Roofing Systems (SIGDERS) research.
