STEP 10
Remove the ventilator
and cut a 300mm
square or round opening
around the centre of the
position marks.
Turn up the corrugations
or pans on both the low
and high sides. This will
help to prevent water
ingress.

Installation - Metal Roof
STEP 11
Return the Maestro BAL
to the roof, positioning
it over the cutout.
Ensure that the top of
the flashing is slipped
under the ridge capping.
For lower pitched roofs,
turn up the top edge
of the flashing before
slipping under ridge
capping. This will help
prevent water ingress.
For BAL compliance, no gaps greater than 2mm may be
present. A water tight install can be achieved by carefully
forming the flashing to the roof sheeting profile, without the use
of sealant.
