With recent sub-zero temperatures this week I've had water dripping from the underside of my sloped roof down into the loft. Not leaks from tiles/felt, but multiple droplets from underside (ie condensation?).
Loft floor is part boarded and mostly insulated with old fibre-glass style rolled insulation between joists.
I'm considering insulating the space under the roof between the eaves to hopefully insulate the underside and prevent the moisture forming and dripping down? However, loft has two large vented bricks at either end which ventilate lots of cool air in the winter, to the point of cold wind blowing through the loft the last week!
With such large ventilated bricks open to the elements, would insulating the underside of the roof be worthwhile or pointless? Should I instead be concentrating on improving insulation on the floor of the loft. Or indeed, insulate both floor and the underside of roof?
Thanks in advance!!
