For projects where the rafters are below the minumum recommended roof pitch, please contact our Technical Department 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 achieved. For further guidance, download the Olympus Installation Guide.

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

Tile Fixing

Sandtoft roof tiles 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 Support on 0870 145 2021
