Roof areas located directly above large wall openings, such as bay doors and loading docks, can be subject to significantly higher wind uplift pressures, especially when these areas are open during a wind event. These increased pressures place additional stress on the roof membrane system, which can cause potential damage if not properly addressed.<\/p>\n

To ensure long-term performance and compliance with IKO Diamond Shield Limited Warranty<\/a> requirements, IKO Commercial specifies enhanced membrane securement in these areas to resist higher wind uplift forces.<\/p>\n

Determining the Enhancement Zone<\/h2>\n

According to ASCE 7<\/b>, a wall is considered to have a large opening when the combined area of openings exceeds 10% of the total wall area<\/b>. The enhancement zone above the large opening is defined as follows:<\/p>\n
