Laying Metal Tiles

The roofing supervisor will establish when the roof should be installed after all sub-trade work has been completed.

All preparatory work of under-flashing, fixing of eaves, gutters and valley gutters must be completed, and all tiling battens must be in place before laying tiles.

If substantial work, such as texturing walls, is to be carried out on a wall above or adjacent to where metal tiles are to be laid, they should be installed after such work has been completed.

Tiles should be inspected and selected, as tiles of a different colour match should not be installed on the same plane of a roof. If more than one pallet of tiles is required for one job, the colour uniformity should be checked.

Tiles damaged during installation must be removed and replaced, and any deformed tiles or tiles with surface damage must be rejected.

Tiles should be laid from the ridge down to avoid unnecessary traffic and can be laid broken bond or straight down the roof.

The eave gutter tiles should project over the edge of the fascia to ensure that water discharges directly into the gutter system and tiles should be laid so they prevent any water penetrating into the roof cavity.

Before tiles are laid, the direction of lay should be determined by:

  • Taking into account whether the profile can be laid only one way or both ways;
  • Appearance, so that laps face away from the line of sight;
  • Allowing for prevailing weather exposure.

Installation of perimeter tiles (excluding eaves tiles) can be completed before the main body of tiles are laid.
