Concrete or clay tiles are loose

Causes

Poor initial installation; tiles not fixed in place

Corrosion of tie wires or clips (visible in the roof space)

Wind causing tiles to vibrate and loosening tie wires

Listed under: finishes, tiles, concrete and cement, concrete tiles, Roof, cladding, wind, durability, corrosion, fixings and hardware, fixings, roof cladding, concrete or clay tiles

Cause

Poor initial installation; tiles not fixed in place

Repair

  • if accessible from inside the roof space, fix loose tiles or replace corroded wire by looping 1 mm (16 gauge) galvanised wire through the lug or hole in the tile and tying the wire around a tile batten
  • where roofing underlay has been installed, cut and fold back a section of the underlay to access the underside of the tiles; fix loose tiles or replace corroded wire; cover the cut section with new underlay and staple it to the tile battens once the tiles have been secured  
  • in very/extra high wind zones, the Territorial Authority may advise that tiles should be nailed; if the tiles do not have pre-formed fixing holes, use proprietary tile clips (available from tile suppliers) that hook onto the tile and can be nailed into battens
