Outdoor ducting material for kitchen extractor?

[Safety First]

Kitchen extractor comes out under/into lean to shelter. Straight into 'clothes drying zone'.

Solution is to extend the ducting up and along the wall to the side of the lean-to roof and out through the feather edge siding..

In winter it's visibly laden with steam/moisture

Won't the ducting accumulate water? How is this dealt with?

Yes massively, especially if there are any dips which will fill with water and eventually block the pipe.

Slope to the external. Rigid duct.

Don't fans evaporate moisture?

Eh?
I've stopped rollicking the electricians now that they have got the message.
I would ask them to trim as much of the excess duct hose as possible, prior to connecting the fans, leaving the duct more taut and vertical, up to the TVT.
Prior to this, they would just attach to whatever was trailing in the loft which would eventually fill with water and sag.
All I need to do now is educate them to wrap the insulation back around the hose.

So set a lower than exit lowest point with weep hole, then install as normal.
