Slate Roofs & Condensation

As a supplier of premium natural slate, we know that this material is unrivaled for its durability and timeless aesthetic. However, because slate is a dense, impermeable material, managing moisture within the roof structure is critical to ensuring that longevity.

With the updated BS 5250:2021 standards, the requirements for protecting your timber and preventing interstitial condensation have evolved. To get the best out of your slate roof, here is what you need to keep in mind:

🔹 Don’t skip the Batten Space: Even with "breathable" membranes, natural slate often requires a 25mm ventilated void created with counter-battens to allow moisture to escape effectively.

🔹 Cold Roof Requirements: Ensure a minimum of 25,000 mm²/m at the eaves and 5,000 mm²/m at the ridge to maintain constant airflow.

🔹 Warm Roof Precision: For insulation at the rafter level, a flawless Vapour Control Layer (VCL) is your best defense against moisture buildup.
We provide the world’s finest slate, but its performance depends on the system behind it. Getting the specification right today prevents costly repairs and structural damage tomorrow.
