More and more people are realizing the need to better insulate their homes to both help reduce their energy bills and reduce their carbon footprint. Although this is generally a very necessary and good thing, improper venting can have some negative side-effects if certain basic precautions are not taken.
One of the most important of these is making sure that your roof is adequately ventilated. Failing to do this can lead to serious damage to your property which can end up with you having to shell out even more than you’re saving on your heating and cooling bill.
PREVENTING DAMPNESS & THE TROUBLE THAT COMES WITH IT
Many homeowners chose to only insulate the ceilings of the top floor of their homes, rather than insulating the roof itself. This is a bad idea as it can cause significant issues with the development and presence of dampness and mold. The problem is that the air in the un-insulated roof space still receives a great deal of heat from the house, making it significantly warmer than the air outside. The inner surface of the roof, however, will be the same temperature as the outside air.
When the warmer air in the roof space comes into contact with the cold roof, moisture in the air condenses on the underside of the roof. This condensation then drips down onto the floor of the roof space where it can quickly begin to collect and penetrate your joists, insulation, and through to the ceiling below. As well as encouraging rot and the growth of mold, this can lead to damaging finishes such as plaster, paintwork, and wallpaper. It can cause insulation to degrade over time.
