How do I stop condensation on my rooflight?

Your home is bound to hold some moisture produced by everyday activities like cooking and showering. Even breathing adds to moisture in the air.

When there is a big temperature difference between the outdoors and indoors, like during winter, this can result in condensation on windows.

You may notice condensation on your rooflight window because warm air, which holds more moisture, tends to rise and then liquefy when it comes into contact with a cool surface. This doesn’t necessarily mean there is something wrong with your rooflight but it is worth checking it has been installed correctly.

When your rooflight is installed, felt should be added between the frame and rough opening to help prevent condensation. When this is not done, you may notice water dripping because of moist air from your room coming into contact with cladding.

Signs your home has too much condensation

A few signs can indicate that you have excessive condensation in your home, including:

  • Mildew on walls and window seals
  • Bubbling or peeling paint
  • Damage to floor tiles
  • Deteriorating furniture
  • Rotting in the structural wood in walls

Preventing condensation

If your house has condensation, you are better off tackling it before it becomes a bigger problem. It may even be causing problems you can’t see.

The best way to prevent condensation in your home is to make sure it is properly ventilated and that air is allowed to circulate. You can help do this by taking the following steps:

  • Open your windows for an hour or two every day
  • Open your curtains and blinds to allow air to circulate
  • Use thick curtains to make windows warmer
  • Use extractor fans in the kitchen and bathroom
  • Install double glazing
  • If you have a furnace, make sure it is letting in fresh air
  • Use a dehumidifier
  • Insulate your home
  • Use a ceiling fan
  • Ensure moist air is vented properly from appliances like washing machines and tumble dryers
  • Avoid drying clothes indoors as much as possible

How our rooflights help prevent condensation

At ROOF maker, all of our Reflex® glass units are constructed with super spacers and the frames themselves make clever use of insulation and thermal breaks. This reduces cold spots on the inside of the rooflight, which helps prevent internal condensation.

Our opening rooflights help prevent condensation by allowing you to keep rooms well ventilated. Our slimline roof lantern can also be fitted with a vent to let in fresh air.
