Cut Hole:
Carefully cut the hole, remembering that there may be insulation and other roof
members under the roof sheet. Once the hole has been cut, fold up the edge of the
corrugations or pans. Ensure the roofing safety mesh/net integrity is maintained after the
installation.
c.
Secure Flashing:
Attach the flashing over the roof hole and back flashing tray to extend the
ridge to the ventilator’s flashing.
Apply sealant prior to final fixing (refer to the table below for
the required number of fasteners). If trimmers are used ensure the flashing is secured to the
trimmers. Seal all fasteners with a suitable sealant to ensure they are weatherproof.
