The Hidden Moisture Problem: Understanding Roof Space Condensation

In this episode of The Masons Podcast, we explore one of the most misunderstood issues in modern homes: roof space condensation.

As homes become more insulated and airtight, moisture build-up in roof spaces is becoming more common. But where does that moisture actually come from? And how can builders and designers reduce the risk?

Masons Technical Manager Arthur Whitfield explains:

·       What causes condensation in roof spaces

·       The difference between cold roofs and warm roof design

·       Why modern long-run roofs can increase condensation risk

·       How moisture from everyday living enters the roof cavity

·       Practical solutions for both existing homes and new builds

Whether you’re a builder, architect, building designer, or homeowner, this episode will help you understand how ventilation, airtightness, and roof design all work together to protect the durability and performance of a building.

If you’re working on modern residential construction in New Zealand, this is essential knowledge.
