    New Roof = Major Humidity/Damp in House

    I don't understand the connection either as I know that the living and loft space are separate but it is literally the only thing that changed. So how to explain???? New roof, new membranes (from the old bitumen ones), new soffit vents (after roofers failed to realize that I didn't have any to...

    New Roof = Major Humidity/Damp in House

    Just an update: I'm fairly convinced that the issues are as follows: - lack of insulation and/or no insulation in some areas of the loft = moisture getting up into the loft + damp feeling in the house - lack of general ventilation in the house (no trickle vents. I do have one air vent in the...

    New Roof = Major Humidity/Damp in House

    Literally not one thing had changed apart from the roof. I did have a gander around the loft this morning. RH is at 54% in the loft which isn't bad but isn't great. Ducting is fine. No water or damp issues from the gable end nor chimney. Chasing roofers to fix a membrane they damaged while...

    New Roof = Major Humidity/Damp in House

    Mine deals with it fine. I confine the space close the door and dont stop until everything is bone dry otherwise I have no way to dry my clothes. That isn't the issue though. My habits haven't changed and I haven't had any issues until now with my most recent reno changes. Any issues with...

    New Roof = Major Humidity/Damp in House

    That's on my checklist for tomorrow. I got home a bit late today to have a look

    New Roof = Major Humidity/Damp in House

    Yes. Previous owners had the cavities filled and has crossed my mind that this may also be contributing.

    New Roof = Major Humidity/Damp in House

    Good shout. It's supposed to get cold and I'm off to my partners on Friday night so won't need to run the dehumidifier at night to keep me comfy. I don't have a water meter and it's not possible to install one with how the kitchen was installed by previous owners. Checked gutters, downpipes...

    New Roof = Major Humidity/Damp in House

    I think you're onto something. I think plan of action is to still check the chimney and gable regardless. Still have the over fascia vents installed for more constant airflow in the loft (it's not *as* bad up there vs living area but still needs some addressing). Get the insulation and gap...

    New Roof = Major Humidity/Damp in House

    There is a problem in the loft but it doesn't seem as bad as in the living space. As I said above the problems in the living space were manageable before the new roof. It is now unmanageable which has had me focusing on the roof/loft space, especially when it became incredibly stuffy and germy...

    New Roof = Major Humidity/Damp in House

    I've contacted my plumber as well. I suspect there are a lot of problems with what the people before me did but was managing in a very careful balance. But it's the new roof that has really sent the house out of whack. The humidity in the living space seems to just be hanging around whether...

    New Roof = Major Humidity/Damp in House

    My plan was to fit firehoods around the downlights in prep for the new insulation (currently nothing in that space which I know is not ideal but is on the "immediate to fix" list). Will also check the duct when I'm up there.

    New Roof = Major Humidity/Damp in House

    Ohhh!!!!!! Didn't think about the chimney or gable tbh. I will check that and see if there is any damp/moisture. I have 2 down lights but nothing changed there. Loft hatch kept closed. When I moved in, I had window condensation on windows when it got colder. My plan was to address this...

    New Roof = Major Humidity/Damp in House

    Yes I pulled back all current insulation as the eaves were initially blocked so have daylight now on both sides. I've done or addressed almost all of what you mentioned in your link - there is potentially draughts and possible problems with sealing of any gaps in the actual ceiling/loft floor...

    New Roof = Major Humidity/Damp in House

    Yes am thinking multiple issues and have to find the new balance. The bathroom has mechanical extraction (into the loft and out the wall) and also keep windows open to ventilate in addition. No tumble drier but do dry clothes with my dehumidifier and fan in the winter. Cooker hood recently...

    New Roof = Major Humidity/Damp in House

    I'm at an absolute loss and so are my roofers and even a family member who, while doesn't live in the UK, builds houses (properly) for a living in a far harsher climate... I had a new roof put on and it's caused chaos with humidity in the living space. Got rid of bitumen and replaced with...
