Condensation in loft
Hi. We have recently moved into a property and had triple glazing installed. On recently installing some loft boards we have noticed a few of them have damp patches. There are no obvious leeks and we suspect that this is a result poor ventilation in the loft area and that we will need some additional tile vents installed to allow more air in the loft space. Does that sound plausible? Thanks
Yea your on right track people don't realise that air flow around the roof is a must like the other tradesmen said make sure you got air flow vents on soffits or fascias & few roof tile vents.
Good luck daz

Yes you have identified the correct defect.
Perhaps try installing easyvents in between the lap joints of the felt within the loft. These open up the joints to allow additional air flow.
You should check if your quilt insulation is pulled back from the eaves and ensure (if applicable) that your soffits are vented.

Pull the insulation away from eves to allow ventilation, and fit 2 roof tile vents on each side of each roof about 3 / 4 ft up from gutter.
Very easy to fit for experienced roofer. Paul
