What’s Under Your Roof Matters: A Guide to Masons Roof Underlays
In this episode of The Masons Podcast, we take a deep dive into one of the most overlooked components of any roofing system - roof underlays.
Often unseen, roof underlays play a critical role in managing condensation, protecting insulation, and acting as a secondary drainage plane to keep moisture out of your building. We break down how underlays work, why they matter, and what to consider when selecting the right one for your project.
We also explore the Masons Roof Underlay range, including VHP Value, VHP Strong, VHP Ultra, and VHP Maxi, along with Masons White Face Foil. Learn the key differences between breathable underlays and foil systems, and where each is best suited.
Plus, we explain what CodeMark certification means and why it’s important for compliance with the New Zealand Building Code.
Whether you’re a builder, roofer, designer or DIYer, this episode will give you practical insights to help ensure better roof performance and long-term durability.
