We get condensation on the inside of our double glazed windows facing
north.

Then you've got unhealthily high RH in the house.


Mould also grows on items that have been handled, due to the
hand-grease and dirt that accumulates on them. If the ventilation is
good, but outside humidity is high, I'd wipe down anything I was going
to put up there to clean it, and then enclose it in a big poly bag.

plastic bagging doesn't prevent damp ingress, but does prevent air movement.


I think I'd be stripping some cable - got loads of Cat5 - wonder if
that'd work! Just a few nails into the mortar around the ridge tiles
should hold it. I'd need about 40m.

Doesn't sound robust. T&E would be more so.
