Note: Unless otherwise stated, data is based on tiles laid at minimum headlap.

For projects where the rafters are below the minimum recommended roof pitch, please contact Technical Services for advice.

**Clay tiles are subject to small variations in size because of drying and firing shrinkage in the manufacturing process. Before deciding on the batten gauge and linear coverage, the roof tiler should inspect each batch of tiles to ensure that the correct minimum headlap and sidelap are achived.

Tile Fixing

Sandtoft roof tiles/slates must be laid and fixed to comply with BS 5534: the British Standard Code of practice for slating and tiling, and BS 8000: Part 6: the British Standard Code of practice for workmanship on building sites.

To ensure compliance with these Standards we strongly recommend that either the recommendations given in the Sandtoft Zonal Method User’s Guide and Zonal tables must be followed where available or a calculated fixing specification must be obtained using Sandtoft’s Fixing SPEC service.

For further information go to Fixing SPEC or contact Sandtoft Technical Services on 0844 9395 999.
