Trying to work out the best way to vent a bathroom using a fan with 4" pipes
and feeding through the roof.
It is a bungalow but there is no way to vent through a wall so it has to be
the roof.
The tiles are concrete, flatish with a square ridged design put there in
about 1950.
Never done a through the roof before so any advice would be handy.
My thought so far are with putting a metal pipe through the tiles similar to
what they fit to gas boiler outlets.
The bathroom ceiling where the fan grill sits is only 3' below the roof
tiles.

Any thoughts?


Marley do a range of ventilator exhausts disguised to look like
regular roof tiles. I've just had one installed in my period cottage,
and it is almost invisible from the outside.
