Today I’m going to talk about condensation in the loft.
In the last 25 years, loft condensation has risen fast. And it’s causing big problems for homeowners.
Yes, it might seem like some harmless, little water droplets. But if you leave condensation to develop over a long time, it can cause issues like damp, black mould, and wood rot.
All of these can impact the health of your living environment, your bank balance, and the value of your property.
In this post, we’re going to look find out if loft condensation is normal, what causes it, and (most importantly) how to stop it.
Is Condensation in the Loft Normal?
Is condensation in the loft normal? Yes! (especially in the cold winter months). Loft condensation problems have increased as modern living habits have developed.
Warmer homes means more warm air rises up into the loft and condensates on the cold inside surface of the roof.
What Causes Condensation in the Loft?
Loft condensation can be caused by lifestyle factors, lack of roof ventilation, or blockages of existing ventilation.
Lifestyle factors include using central heating systems, taking more hot baths and showers, drying your washing indoors, double glazed windows, and cooking without an extractor fan.
When it comes to roof ventilation, you might just not have enough to take in fresh air and exhaust any stale, warm air. Or your existing ventilation could be blocked by attic storage boxes or new roof insulation (this is common for homes with soffit/eaves vents).
How to Stop Condensation in the Loft Space
Enough about problems. We need solutions!
There are many ways to reduce loft condensation (with varying impact).
You could cut back on your lifestyle factors like using the central heating less or taking less showers. But is that really realistic for most people? No.
You could dry your washing outside. In the summer, most people do. In the winter? That’s a no too.
And how much difference would all of the above actually make? Hard to say.
How to Stop Condensation in the Loft is a Different Question
And the answer is better roof ventilation.
So whether that means unblocking your soffit/eaves vents or adding more roof tile vents, you or your roofer will have to figure that out.
Yes, we’re biased - we think our roof tile vents are the best option because you can use them for loft ventilation. But you can also connect your bathroom extractor fan to vent it through the roof.
Combining these two solutions is the best way to stop loft condensation because you are removing one of the main sources of warm moist air (the bathroom) and also creating outlets for the warm moist air that reaches the roof space.
So take a look at our roof tile vents for bathroom extractor fans and roof ventilation. We have a wide range of products for different profiles or roof tile. And we make everything in-house so we've got the best colour range on the market!
