What is a Roof Tile Bedding Mortar?

Roof tile bedding mortar is a mixture used to secure roof tiles in place, preventing them from shifting or becoming dislodged over time. Made from sand, cement, and water, it is applied as a bed for the tiles, typically under ridge and hip tiles, where movement is most likely to occur. Bedding mortar stabilises the tiles and helps ensure the roof’s long-term performance, particularly in areas subject to high winds or extreme weather.

Functions of Roof Tile Bedding Mortar

The main role of roof tile bedding mortar is to secure roof tiles firmly. It serves several important purposes:

Tile Stability: It holds the tiles in place, preventing movement due to wind or other external forces.
Water Resistance: Bedding mortar helps reduce the likelihood of water getting underneath the tiles by filling small gaps between them.
Durability: It ensures the long-term integrity of the roof by preventing the tiles from loosening or dislodging over time.

Why Roof Tile Bedding Mortar is Important

Properly applied bedding mortar is crucial for roof stability. Without it, tiles may shift, crack, or become loose, increasing the risk of leaks or roof damage. The bedding mortar creates a secure, uniform surface for tiles to sit on, making the roof safer and more durable.

How to Apply Roof Tile Bedding Mortar

Applying roof tile bedding mortar involves a few key steps:

Surface Preparation: Make sure the roof battens are clean and free of debris.
Mix the Mortar: A typical ratio is 4 parts sand to 1 part cement, mixed with water until the consistency is firm but spreadable.
Apply the Mortar: Spread the mortar evenly across the roof battens where the tiles will sit, especially under ridge and hip tiles.
Place the Tiles: Press the tiles into place while the mortar is still wet. Ensure each tile is aligned correctly.
Let It Set: Allow the mortar to set and harden for 24 to 48 hours.
