9 Roof Penetrations
9.1 Roof Penetration
For On-Roof Systems Only
1. There are several options for
making weathertight roof
penetrations, including:
Ventilation Tiles
Increase the opening in the
ventilation tile to allow the Insulated
pipes to pass through, or remove
the grill inserts if possible.
Locate the ventilation tiles adjacent
to the collector connections.
Lead Flashings
Remove the tiles adjacent to the
collector connections. Drill a 25mm
hole in the tile using a diamond
tipped bit.
Locate the flashing below the drilled
tiles, with the copper pipe passing
through the drilled hole
‘SolarDek’ Flashings
These have a coated lead base with
a silicone centre section that is cut
off to suit the diameter of the pipe.
These can replace the tiles adjacent
to the collector connections.
