    Retrofitting roof ventilation on vaulted ceiling

    Hi, I have a vaulted ceiling. The vaulted part is about 1.5 metres long, contains Celotex insulation with a gap between the insulation and the felt, and leads into a normal loft.

    Hi, Attached is a photo of my outside tap (it’s usually connected to a fence but I’m changing a rotten panel). There is a small weep coming from the edge of the black plastic adaptor (if it is an adaptor) that connects the tap to the wall mount. That bit of plastic is a bit knackered- I tried...
