Airing out: loft ventilation

Loft ventilation is essential for a cosy and healthy space, especially if you’re living in it. It helps maintain a comfortable temperature year-round, preventing the loft from getting too hot in summer and keeping it warm during winter. Proper ventilation also controls moisture, stopping condensation in its tracks to avoid the bigger issue of mould and other damage. Plus, it freshens the air, making it safer to breathe. Not just that, good airflow contributes to energy efficiency, potentially lowering utility bills. So, whether you're converting your loft or already living in one, ensuring proper ventilation is a must for a happy and thriving loft experience.

Adequate roof ventilation is factored into houses when they’re built, but things can change it over time to affect its efficacy. Adding something that made the loft area cooler, like extra insulation, can impact the effectiveness of the ventilation. Similarly, doing something to block the existing vents partially or completely will also mean extra ventilation may be required. If you’re worried about condensation in your loft, check that insulation is covering your existing vents. It’s also good to make sure that excessive water vapour isn’t coming up from the house through gaps around light fittings or a loft hatch that isn’t properly fitted.

When it comes to loft ventilation, you've got options. Roof vents, like ridge vents and turbine vents, keep your loft fresh by letting hot air escape. Soffit vents work hand in hand with roof vents, bringing in cool air from outside. Tile vents have the desired effect while offering a more seamless look that blends in with the roof. If you want control, louvre vents let you adjust the airflow. No matter the size or climate of your loft, there's a solution out there. No matter the type you choose, you should make sure that you’re achieving good cross ventilation. That means fitting vents on opposite sides of the loft to make sure that there’s are separate entry and exit points for wind draughts.

If your loft is feeling hot and stuffy, or you’re noticing musty odours, it could indicate a need for more ventilation. Condensation on windows and walls, along with mould or mildew growth, are clear signals of excess moisture due to poor airflow. If you're struggling to maintain a comfortable temperature or notice higher energy bills, insufficient ventilation might be the culprit. Don’t fret though- it’s relatively simple to resolve just by adding some additional ventilation.
