Membrane roofs are ubiquitous on industrial, commercial, and institutional buildings and cover many multi-family and some single-family Part 9 structures. But a poorly designed and constructed membrane roof can succumb to the powerful uplift forces of wind, leaving the building interior vulnerable to the weather. Flying roof material can also pose a serious risk to public safety. Designing a wind-resistant membrane roof system is prudent. It is also a Code requirement.
