PRE-INSTALLATION CHECKLISTFor Metalcraft Metal Tiles

In order to achieve best results and a fast hassle free job it is the customer’s responsibility to ensure that the following requirements are

met prior to installation. The builder is responsible for erecting framing and timberwork; however it is the tilers duty to check that the

framing is accurate and sufficient before installation. All roof structure and bracing requirements must be installed to comply with the

NZS 3604. Alternatively the structure should be designed by a Design Engineer.

SCAFFOLD/ACCESS

For working heights greater than 3 metres Scaffold or edge fall protection

must be provided and installed by a certified company as per OSH

regulations. This will ensure the roofers safety whilst working at height but

easy access to the roof will also speed up installation.

For best results we recommend having scaffold or a working platform by

gable ends as this will ensure clean, straight lines on your gable tiles or

flashings.

SITE ACCESS

Metalcraft Tiles are delivered by on pallets by HIAB truck. Please ensure

there is clear space as close as possible to the roof access for tiles and

battens. By dropping the materials as near to the site as possible installation

will be sped up and the risk of walking dirt onto the roof will be minimised.

This will also diminish the risk of fixers slipping which can be the result of

muddy shoes on roof framing.

FASCIA

Roof installation cannot start until timber or metal fascia is in place. This

is essential to determine accurate overhang into the gutter for the bottom

course of tiles.

VALLEY BOARDS

Valleys should be formed by fixing 150x25 rough sawn timber valley boards

in between jack rafters/trusses and must sit flush with the top of the

rafters.

The outer edge of the valley board must be set to a minimum of 150mm

from the centre line of the valley. It is important to ensure valley boards

are not only straight but strongly secured as they are often a main point of

access for the tilers.

WALL TO ROOF JUNCTIONS / Z-FLASHINGS

Wherever the roof meets a wall Z-flashings will be installed by Metalcraft fixers. Walls should be nogged at the correct height by

the builder prior to installation of side flashings.

This should be 90mm from top of truss to bottom edge of the nog and should be flush with outside edge of stud

90mm
