My house is north facing and I live in the north east. It was built in 1962 or 1964 and has wooden soffits covered by uPVC. Inside, the bedrooms have sloping ceilings at the wall ends. We've had a damp problem on the sloping section. On checking the loft, the insulation has been stuffed down towards the eaves completely blocking it. I have cleared it but there appears to be no ventilation, no sign of daylight or vents. Should there be insulation down the slope in the loft but leaving a gap for venting? Do I need to get vents put in the soffits? The front of the house is also tiled from above the downstairs window up to the soffits. Any help on this would be really appreciated.
