  • Ideally soft water.

2. Clean the window pane

Ensure that when cleaning the pane that the sash is rotated 180 degrees. The sash must be secured so that you are able to clean this hands free. To secure the sash in position; slide the barrel bolt into the bushing at the bottom of the side frame. This should click on most windows when in place.

You must clean the pane with a clean and soft cloth, sponge or a non-metal squeegee. Make sure you are not using any scourers or metal scrapers to clean the pain as it can leave scratches or indents on the pane of the window.

Depending on what you have readily available you could use anything from clean soft water or even ordinary household cleaners as long as it is non-abrasive. In locations where it is hard-water make sure that you add a little detergent to soften the water or wipe off all excess water after cleaning the pain.

Once you have used your cleaning solution / water you should immediately use, ideally squeegee but a soft cloth can be used also. This is to ensure that you get all of the excess water off the pain and leave no water marks on the window. By using a cloth it can sometimes leave water marks depending on the technique.

Make sure that if using a squeegee that you don’t knock the pain with any metal parts of the cleaning equipment you are using, or any abrasive materials. By doing so could cause permanent damage to the pain.

Tip: When cleaning your roof window it is always best to do it in mild and dry conditions. Prevent cleaning during the hot weather as this can dry up the water quickly and cause streaks.

Tip: Depending on how many roof windows / skylights you have start by cleaning the top one and work your way down. This is in case you get any splash backs etc from cleaning the window above.

Tip: Do not use any cleaning products containing abrasive particles or any chemical products that could affect the window.

Tip: Remove any jewellery when cleaning the pain. bracelets or any other metal objectives could damage the window.

Tip: Never attempt to clean off dirt on the pane without first applying water.

Tip: Try to avoid the silicone on the frame when cleaning the window especially if you are using specific window cleaner.

Tip: If any works are taking place in the vicinity of the pane, protect the pane with a clean plastic sheet to prevent any splashes or staining from aggressive and abrasive compounds.

Roof Window Radiator Condensation

3. Clean the flashing

When cleaning your flashing there isn’t much you need to clean unless you have severe grime depending on the exterior of the building. Normally flashing keeps quite clean with the rain washing away most of the dirt and grime off the exterior surfaces.

Flashing is weatherproof and makes sure the window seamlessly fits within your slates / tiles when fitting a roof window to a tiled roof. The flashing has the same purposes as a tile in that it helps the water flow away and preventing water from seeping in. With this in mind you should ensure that then the water is running away smoothly. So make sure all leaves or debris is removed from around the flashing at least once per year depending on the location of the building. If you are surrounded by trees this may need to be done more often.

Tip: Check flashing in the winter – Remove any snow or ice to allow the melted water to drain from and around the window. This could prevent any water damages to the building.


Struggling with condensation?

Condensation is the build up of water on a cold surface when humid air is in contact with it. This is predominantly found in high humid rooms such as kitchens and bathrooms. Here are a few tips on how to reduce the condensation on your roof window:

Tip: Close the doors of any high humidity rooms such as kitchens and bathrooms.

Tip: Try Ventilate rooms regularly for five minutes at a time at least three or four times a day.

Tip: Maintain a constant room temperature of 20 degrees celsuis if possible.

Tip: This is ideal for anyone fitting a roof window however, your roof window maybe a victim of condensation depending on the humidity and moisture of the room that it has been installed in. To minimise this from happening or if you are looking to install a roof window in a high humidity environment, look at installing a radiator directly below.
