155 - ZIP-R on the Roof? Structural, Hygrothermal & Durability Tradeoffs

Can ZIP-R panels work on a roof—and should they? Steve, Jake, and Nick Sabol from Huber’s Technical team dig into a topic that’s getting a lot of attention in the field.This episode breaks down the full set of considerations behind putting insulated sheathing on the roof deck: structural loading, fastening and shear, hygrothermal behavior, condensation risk, and long-term durability. The crew looks at where the idea makes sense, where it doesn’t, and what you need to understand before trying it on a real project.It’s a detail-heavy conversation that connects theory to field conditions—exactly where most “good ideas” succeed or fail.
