Fixing terracotta and cement tiles

Both terracotta and cement tiles are fixed to timber battens with wire clips, nails or screw fixings. Manufacturers provide fixing specifications. Specialised capping tiles are laid along ridges and hips. These must be pointed with mortar to ensure adequate fixing and waterproofing.

Six diagrams: 1. Placement of capping, grout and sarking around roof tiles. 2. Scribed and profiled trimming mould fixed to barge board. 3. Patent tile clip spike driven into batten and to clamp the tile to the roof; this means tiles can be produced without holes which are at once expensive and faulted. 4. Cement grout packed between tile and fibre cement strip. Fibre cement strip fixed to top of barge board. 5. Clout driven through lower tile into tiling batten; some problems encountered if the hole in the tile is blocked causing tiles to break or crack later. 6. Patent metal barge capping and timber barge.
