Vapour barriers are applicable to all flat roofing systems. A properly installed flat roofing system  should include a vapour control layer. A vapour control restricts water vapour from the dwelling damaging the insulation in a warm deck scenario  ie where the insulating material is fitted to the roof decking. Over time condensation can also cause any timber or support joists to rot. Replacing this is an extremely costly procedure, so to avoid this problem a vapour barrier control layer and insulation should always be fitted in your flat roofing system.

It is installed directly to the roof decking and should be fixed to the decking with clout head nails and sealed on the laps and perimeter. Few are aware of the importance of this layer, but when you consider the amount of moisture that can build up in a standard house youll understand why these are necessary. A typical family home with two adults and two children living under normal conditions can create up to ten Litres of moisture over a 2. The moisture or water vapour has to go somewhere, and unfortunately not enough properties are adequately ventilated or insulated correctly to deal with this.

These new developments cut out all the previous forms of ventilation and heat the property during the winter months. The warmer air will carry higher levels of moisture. Air will shed this excess moisture when it meets a cold surface. This is called the dew point. Properties with swimming pools will be exposed to particularly high levels of water vapour. Some rooms of every property are also more susceptible to vapour damage than others. Kitchens and bathrooms, for example, are more likely to suffer from problems with condensation. Controlling moisture in a property is very important. Specialist building contractors will be able to assist and make recommendations. If your property meets any of the criteria that has been highlighted in this article, it is best to get professional help immediately, as delaying it could make matters worse.
