Roof Vent and Loft Ventilation


Everyone has heard about roof ventilation, and everyone's heard about insulation. Do you know what it does? Or why is it needed? The reasons for it are given below. So to first understand what roof ventilation does. To understand that you need to know about the role of ventilation during each season.

During the winters warm moist air can build up in the roof space that has been generated from the rooms below, potentially condensing on any cool surface in the attic. This humid and damp environment can lead to rot, mould, and damaged timbers. It can also at times stop the insulation from working properly. In very cold and exposed areas a buildup of warm and moist air inside the loft can under the right conditions create ice dams and guttering at the bottom of the roof.

This happens when warm unventilated attic air melts any snow settled on the attic roof it subsequently trickles down into the property. In hot weather, you may feel the effects of an unventilated roof. The heat from the sun builds up inside the roof space throughout the day and it gradually gets hotter and hotter through a process known as solar gain. Not only can this trapped heat make a lofty smell, but it can also prematurely damage the bitumen under sacking if you have any.

But probably the worst effect it may cause that you're familiar with is the buildup of heat inside the home as it radiates back into the room below, particularly on hot humid nights. So to prevent any of these issues get roof insulation blanket and a radiant barrier installed immediately.
