How to prevent condensation on your roof windows

No matter how great modern technology is, sometimes remote controls can get out of sync with other products.

Roof windows are the ideal way to add natural light into your home.

Natural light not only transforms dark and unused spaces into open areas full of potential but also brings many health and wellbeing benefits.

With roof windows, you can achieve your dream home while feeling healthier, happier and more comfortable.

With roof windows, the last thing you want to worry about is condensation on your windows. To protect the life of your windows and make sure that your home doesn’t suffer, we’ve put together this guide to preventing condensation on your roof windows.

What is condensation?

Before you can prevent condensation from building on your roof windows, it’s important to understand exactly what it is and the damage that it can cause.

Fundamentally, condensation is water.

It happens when the moisture in the air is quickly cooled, forming water droplets over windows, walls or other surfaces.

During the winter, the temperature difference between the inside and the outside causes more condensation to appear.

The moisture in the air comes from a range of everyday actions, such as breathing, cooking, cleaning or through the bath or shower.

The more moisture in the air, the more condensation that will form.

Over time, condensation can start to ruin and damage your surfaces and windows causing damp. If left untreated, the damp can cause mould and lead to a range of health and wellbeing issues, including triggering breathing problems such as asthma, increasing dust mites which can cause allergic reactions or even cause throat or lung illnesses.

If you’re starting to notice condensation, it’s important to take steps to prevent condensation from building up in your home.

How to prevent condensation?

Condensation builds when there’s an excess of moisture in the air. So, the best way of preventing condensation is to reduce this amount of moisture.

Reducing moisture can be achieved by completing actions such as using extractor fans when cooking, drying clothes outside or in a tumble dryer or opening roof windows when possible.

In addition, dehumidifiers will also help capture and dispel the extra moisture in the air, keeping your home free from condensation.

One of the best ways to keep the moisture levels in your home down is by making sure you use a ventilation system. These will help remove the condensation and humidity from the air, making sure its fresh, clean and breathable.


To prevent condensation, you need to keep the moisture levels in the air low. Without it, the condensation can cause damp and damages to your home and roof window as well as a range of health and wellbeing problems.

To keep your roof window in its best condition, make sure that your house has a proper ventilation system to keep the air clean, dry and breathable.

At LB supplies, we provide roof windows with built-in ventilation systems, which will protect it and your home from condensation damage and keep it in its best condition for years to come.
