Condensation on Breathable felt

[Prior69]

I found that by getting air into loft by moving the insulation back from the soffit area worked.

Its been just as cold as it was last winter and I've had zero problems this year.

So I guess what I'm telling you is that you need to check the ventilation in the roof - if you cant make some ventialtion via the soffits you may need to get some vent tiles in.

Thats what i was going to say

"breathable" underlays are good but not magical.
They will allow a certain amount of moisture through but not a lot.
The secret to eliminating condensation in your roof is to stop the warm moist air getting into the loft in the first place.
Flush mounted cieling lights, poorly fitting loft hatches all will let vapour into roof.
You need to ensure adequate air movement in the roof ie ventilation.
Over fascia vents, vent tiles and vented ridge will all help.
ALso if you have upgraded your insulation make sure the insulation isnt touching the underlay over the wall plate.
Insulation interuptors are useful.

The point is is there's no point just dragging up old threads for the sake of it!

If you are going to drag up an old thread at least add some new advice.....
