Concrete or clay tiles broken or cracked

Cause

Wind or frost damage

Repair

  • replace the damaged tiles. Carefully lift adjacent tiles, remove the damaged tile, insert a replacement tile, replace the adjacent tiles, and then fix the tiles. Replacement tiles should be fixed with hot-dip galvanised nails or screws in exposure zones B or C, and 304 or 316 stainless steel nails or screws in exposure zone D (coastal).
  • All perimeter tiles must be fixed, including each tile adjacent to a ridge, verge, hip, valley or eave. For other tiles, every second tile in each row must be fixed so that each unfixed tile is interlocked with a fixed tile.
  • Where new replacement tiles cannot be found, contact building recyclers. An exact colour or design match may not be possible as manufacturers often had their own designs.
