Why do I have condensation on the inside of my roof?
Condensation occurs in roof spaces when there is either too much warm air circulating upwards from living spaces, or when there is inadequate roofing ventilation. Older homes tend to have a degree of natural ventilation due to less accurate building methods, therefore offering more opportunity for moisture to escape.
Why is my roof sweating?
Since warm air has moisture, the moisture then condenses on the inner roof surfaces when it comes into contact with cooler temperatures. This resulting problem is often due to improperly installed insulation. When there’s too much insulation, it tends to trap warm air near the roof, causing condensation.
What causes condensation on inside of roof felt?
Warm moist air enters the roof space through gaps in loft hatches or where bathroom plumbing or other services go through the roof space. When this warm moist air hits the cold air in the roof space, water droplets condense on the nearest cold surface – the roofing felt.
Do roof vents stop condensation?
Loft vents help to move moisture-laden air (which may condense and cause mould) up out of your roof space – ultimately reducing condensation.
Is condensation in loft a problem?
Loft condensation is a common problem and usually affects homes in the winter when the loft is so cold that condensation forms as water droplets on the underside of the roofing felt.
Why is the underside of my roof wet?
Warm wet air can also enter the attic through holes in the ceiling, commonly at plumbing and electrical penetrations. This warm, wet air condenses and then freezes on the roof deck underside. As the day warms up, this frost melts and drips down. This is the dripping that you see from the living space below!
