Is Your Loft Damp Actually a Problem? A Roofing Reality Check

John has been dealing with condensation in his loft and has already had advice from roofers suggesting extra ventilation. In this video, Roger takes a closer look at the issue and explains what might really be going on. We look at lap vents, breather membranes, open cavity walls, roof ventilation, solar panels, mould staining and whether the marks on the underside of the roof felt are actually something to worry about. Roger also explains why sealing the top of a cavity wall can help stop moisture evaporating straight into the loft space, and why clean, dry roof timbers are usually a good sign. If you have damp, mould or condensation in your loft, the key is to understand where the moisture is coming from, how it is escaping, and whether the roof structure itself is being affected. Keep your questions coming in — and send plenty of photos, including the wider view, the outside of the house, the age of the property and any relevant details. _______________________ Got a question of your own?
