Flat Roof Window Condensation

Our photograph at left shows severe alligatoring on a nearly flat low slope roof that also was relying on tar and roof cement to try to stop parapet wall leaks.

Flat roof window condensation.

Condensation is more prevalent in new homes. When there is a big temperature difference between the outdoors and indoors like during winter this can result in condensation on windows. It s the excess moisture in the room. The problem however usually isn t the roof window.

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. Condensation builds when there s an excess of moisture in the air. Condensation can cause a number of problems within a building particularly interstitial condensation which can occur inside the roof s structure. Condensation is usually more noticeable on roof windows and flat roof windows because warm moist air rises to the ceiling.

Condensation and roof windows due to the position of roof windows they are more exposed to the elements. Interstitial condensation creates structural damping and subsequent damage that occurs when moist air penetrates inside the hidden space within an enclosed wall roof or floor cavity of a home. Over time this excess moisture can lead to the unseen decay in roof timbers and fixings. Flat roofs and low slope roofs also face potentially serious condensation problems that can in turn lead to costly rot or mold damage in buildings.
