The Hidden Moisture Problem: Understanding Roof Space Condensation

4th March 2026
Description

Condensation in roof spaces is becoming more common as homes become warmer and more airtight. In this episode, we discuss why it happens and what can be done to manage it.

Arthur Whitfield, Technical Manager at Masons, explains how moisture enters roof spaces, why long-run roofs are more susceptible, and the key steps designers and builders can take to reduce condensation risk.

We also cover ventilation, airtightness, and the difference between cold and warm roof design.

A practical conversation for builders, designers, and anyone interested in better building performance.
