Laying Metal Tiles

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

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.

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 from penetrating the roof cavity.

Before tiles are laid, the direction of lay should be determined, taking into account whether the profile can be laid only one way or both ways.

Direction of lay may be influenced by a desire to face laps away from major lines of sight, direction of prevailing weather, or sequencing of construction.
