Hi all,
we had our loft re-insulated last year, back in March. I have since noticed that it is starting to get damp up there (condensation on the underside of the sarking felt). On the basis that in the past 3 years it's been bone dry, I am assuming that the insulation is now preventing the natural damp from drying.
At present, there are no soffit vents. Could I simply cure the problem by installing a few ? If so what is the best spacing ?
Alternatively I have seen you can get these roof vents which replace a tile, can anyone comment on whether these are a viable alternative ?
Thanks in advance
