Building codes and standards specifies pressure coefficient data for wind design of commercial roofing systems. It mostly derives the data from wind tunnel studies. Roofing community in North America has undergone much change over the last 25 years a

At the National Research Council of Canada in November 1994, members of the North American roofing community {manufacturers, building owners, industry association and research agencies} met and agreed that a means of evaluating the effect of dynamic

Research was conducted on mechanically-attached roofing, low-slope assemblies to study the effect of air intrusion on performance. The research generated wind uplift data two for different roofing configurations: 1) assemblies without air retarders a

Majority of low-sloped roofs are constructed as conventional membrane roofing assemblies (membrane above insulation). Currently, four types of conventional assemblies are typically in use: 1. Mechanically attached assembly, 2. Loose-laid ballasted as

A roofing system (RS) consists of a waterproof membrane, mechanical attachments, cover board (if present), insulation, and vapor or air barrier (retarder - if present). A roof assembly (RA) is defined as an RS that includes a structural deck. Wind up

This research investigated the behavior of mechanically-attached, single-ply roofs subjected to wind uplift, and resulted in a standard for assessing the air intrusion characteristics of roofing assemblies. The paper describes the test apparatus and
