Condensation in roof space

So bought an x-council mid terraced house (front faces west, back faces east) built in the 60s in 2017. The year we got the house we put in a raised flooring over the fiberglass insulation so you could walk round the loft space and the roof looked at. There was a ridge tile halfway down the roof and after posting the job got a qualified roofer out. The roofer said everything looks fine just need to rebed the tiles and good to go. July 2018 we got the soffits, fixtures and fascias replaced as they were asbestos (again an accredited company did the work) and as they looking sorry for themselves with bits flaking off they got replaced with UPVC. The new fascias /soffits / guttering looked really nice and allowed air to flow through the roof as the - what I can only say feels like plastic sheeting that goes the entire length of the roof space between the roof tiles and wooden rafters would in russle the breeze on the occasions I did enter the loft. November 2018 we got the front windows replaced. Although the original ones were double glazing they were drafty and no heat was staying in the front rooms. As soon as they were replaced again with newer double glazing the difference was definitely noticed. We are also due to get the back windows replace December this year (2020) along with a new front door. So that for all the work on the property and as the gas / electricity bill went down I was pretty happy. Now for the advice bit. For the first time since we brought the property, I've noticed condensation in the roof space for the first time while getting the Christmas decorations down (2020). The condensation favors the east side more than the west of the property. Its got to the point where I took a towel up there and it came down dripping wet. The sheeting between the roof tiles and rafters is just soaked! I get it's winter but this really is something else. As for the plastic type material that's soaking wet I could not tell you what it is as it was here when we brought the property. It's been suggested to attempt dehumidifiers up in the loft? But I'm not convinced on this solution especially when it's never been an issue before. We are doing nothing different in the property (extractor fan on when cooking - sauspan lids on, window open in upstairs bathroom for a good 20 minutes after finishing in the shower /bath or longer until the mirrors unsteem- there isn't an extractir fan but thinking of getting one put in when re-modle the bathroom, the combi boiler expels directly out the the back of the house on the ground floor) So why all the condensation in the loft space??? And what could be done about it? Im asthmatic and don't exactly want to be dealing with mould growing and with making the property even less drafty with the replacement of further windows and front door I fear the situation in the loft will only get worse. So any thoughts and advice would be much appreciated.
