In this episode, we unpack the role of roof underlays - the hidden layer that plays a vital role in protecting your building.

We discuss how underlays manage condensation, act as a secondary moisture barrier, and contribute to the long-term performance of your roof. The conversation also covers the Masons Roof Underlay range, including VHP Value, Strong, Ultra and Maxi, plus White Face Foil, and the key differences between breathable and non-breathable systems.

We also break down CodeMark certification and what it means for meeting New Zealand Building Code requirements.

A practical listen for builders, roofers and designers looking to better understand roof systems and product selection.
