We live in a 1960's bungalow that was built on low lying, boggy land, so that we are in a fog/frost pocket that means the humidity in the house can be high. When the weather is very cold we get damp on the underside of the roof felt that wets the tops of the timbers, where they touch the felt, and can drip down onto the loft floor
We have improved the ventilation by vented bricks on the gable ends, vented roof tiles and vented sofit boards, but clearly still not enough. I think that the roof has been replaced at some time, as we seem to have 2 layers of roofing felt, the lower one is torn in places. We are thinking about a new roof and are asking if we should replace all the felt with breathable felt, and is it likely to help in solving the problem?
TIA
