The merits of having the right cover board

By Dani Sheehan. 

From an increase in severe weather events to the rise in popularity of green roof systems, the use of a high-performing cover board will add life and durability to any commercial roof system.  

During the 2024 International Institute of Building Enclosure Consultants (IIBEC) International Convention and Trade Show, we visited USG Securock® Brand Specifications Manager Frank Arevalo for a live interview to discuss the importance of high-performing cover boards in roofing systems and look at some emerging trends in the industry.  

Frank shares, “We're seeing more severe weather occurring and it's a trend that's not going to be fading anytime soon. So, because of that, the use of a cover board or a roof board in the system enhances the performance and durability of that roof system.” 

He shares some of the products they have available: “We have a gypsum-fiber roof board product that's our universal product with all the major system manufacturers. We have a coated glass-mat product, gypsum-based, that is utilized with adhered systems and cold applications. We have a glass-mat product as well. Both are ultra-lightweight technology, addressing contractors' concerns regarding weight and handling and making things faster in their production.” 

Frank takes Heidi around the corner for a live demonstration to show why a cover board is critical to your roof system. Using a single ply membrane without a cover board, he shows an impact test with a nail. Without the cover board, he can puncture the membrane and reach the insulation with minimal pressure. With USG Securock® Gypsum-Fiber Roof Board, the membrane stays intact. He explains, “You can see here there is no puncture through the membrane. Now, you might dent it a little bit, but that’s showing you the merits of why you want to consider the use of a cover board. It’s not going to leak. Which is the key to durability.”
