Description
As winter sets in and temperatures drop, there’s an increasing risk that moisture will condense in the roof space and cause problems. The source of the moisture – and therefore the solution – isn’t always obvious.
Condensation in the roof space of a house can cause a range of problems including mould, a reduction in the effectiveness of insulation and, in some cases, a reduction in the lifespan of the roof structure.
Scope
This article includes:
- Look down, not just up (roof space moisture sources)
- Warm roofs make condensation unlikely
- Tackling the problem in cold roofs
- Roof ventilation
