* where the pitch of the roof is greater than 26 degrees, should be positioned as close as feasible to the underside of the roof and in no case more than 500 mm below the roof edge
    * should have a guardrail. The top rail should be located at an effective height of not less than 900 mm above the point where the roofline projection intersects the guardrailing, installed with 450 mm midrails
    * where there is an increased risk of falling due to slippery roofing materials (such as fully glazed tiles or the presence of dust, moisture or oil on roofing) should be positioned not more than 500 mm below the roof edge, regardless of roof pitch
    * should incorporate a toeboard at the platform's outer edge
    * should be extended to finish not more than 225 mm from the building face or be fitted with edge protection on the platform's inner edge
    * should be kept clear of equipment, materials and debris.
For further information about the protection components, refer to AS 4994.

Figure 23 Catch platforms for roofing work

9.5 Steep roofs
Where the slope of a roof exceeds 35 degrees the roof is an inappropriate surface to stand on, even with guardrailing or a catch platform. In these circumstances, roof workers need a system to prevent both sliding and falling from the perimeter, comprising two or more of the following:
    * a work positioning system
    * a roof ladder
    * a scaffold platform, located at the roof edge.

9.6 Installation of sarking – tile roofing
If sarking is used the laying of sarking should be done simultaneously with the installation of the battens. Lay the first sheet of sarking and install battens over the sheets, then lay the second sheet and install battens from the bottom of the roof to the apex.

9.7 Installation of perimeter battens – metal roofing
Fastening of the perimeter battens to the hips and valleys may be done by affixing those parts of the perimeter battens that can be easily reached from a position on ladders or from inside the trusses. During the sequential battening of the body of the roof, the remaining length of the perimeter battens can then be secured.

9.8 Fixing fascias and gutters
On houses with no eaves, fascias and gutters may be installed by working from trestle scaffolds or ladders from inside the house frame.
Where the design involves eaves, an external platform should be provided for fascia and gutter installation work. All external work platforms above 2 metres should be at least two planks (450 mm) wide. Guardrailing should be fitted where the there is a risk of injury due to fall. If a gutter
