Building Enclosure - Why Roof Cover Boards Matter
Roof cover boards may be out of sight, but they are the critical layer driving long-term performance.
In an era of increasingly demanding performance requirements for commercial buildings, low-slope roof systems must do far more than meet minimum code - they must deliver resilience, durability and long-term value.
While membranes and insulation often dominate the conversation, this article reveals why roof cover boards are the unsung workhorse of high-performing roof assemblies. From enhancing fire resistance and wind uplift performance to protecting against foot traffic, hail and thermal cycling, cover boards play a critical role in meeting ASTM, FM, UL and IBC requirements while extending roof service life. Backed by testing data and real-world performance insights, this piece makes the case for treating cover boards not as an optional layer, but as a foundational component of resilient roof design.
Read the full article on Building Enclosure to discover how roof cover boards quietly drive compliance, performance and longevity in today’s most demanding low-slope roof systems.
