Hi All,
All the time we've lived in our bungalow (6 years) we've had a minor issue with condensation in our loft. I say minor, because until now it hasn't really caused us a problem.
So every winter, condensation forms on the inside of our roofing felt, and then drips onto the insulation. It's never been enough to soak the insulation or come through onto the ceilings. But if you go into the loft, there will be odd patches of damp insulation, and you can see condensation droplets on the high level parts of the roof.
We've never used the loft for storage bar a few boxes, but we've now got a load of baby stuff up there, and I noticed at the weekend that some of this is going mouldy.
So clearly we need to think about ventilating our roof. There is nothing in place at present. The bungalow was built in 1981 and has a tiled roof.
I was planning to fit some 70mm round vents in the soffits, one between each rafter. However, presumably I'm going to need some high level ventilation to act as an exhaust. Or will the vents down the other side of the bungalow act as an exhaust? We live in an isolated area flat area with fields front and back, so the wind can get very strong.
What is the best option for retrofit exhaust vents? DIY if possible. My concern is that our felt, although intact, is quite brittle. I want to resolve this but not at the expense of ruining our felt / creating a leak!
We're already well ventilated within the house with extractors in the kitchen and bathroom. We dry washing in one room but always with a dehumidifier running - we've got no issues with mould within the bungalow.
All advice welcome
Leccy.
