Fig. 4.8 Feeding the pipe through the sarking membrane
If there is a sarking membrane, proceed as follows:
• Cut the sarking membrane vee-shaped.
• Fold the upper, larger tab on the roof batten above,
and the lower, smaller tab on the roof batten below.
• Fix the sarking membrane tight to the roof batten.
This ensure that the dampness flows away to the side.
• With the roofs activated, cut out a hole with the com-
pass saw.
• Work the roofing felt as described for the sarking
