Any roofers on here??? I know its cold, but I am getting a lot of condensation in the loft area of a new extension, the water is forming physical water droplets which are staining the timbers and making boxes up there very damp and not sure why or how to fix it? It has a breathable roof membrane, and I have over facia vents along the facia boards, and it has 300mm of loft insulation. Why am I getting build up of condensation still? Any ideas, or anyone want to come and have a look? Thanks
