Hi ETC, Thanks for the reply. Could you tell me what continuous eaves ventilation is?

Hey Mike, Thanks for your reply. So the vents have been installed and the felt has been cut out so they're exposed in to the eves. Looking at that link you've sent, me not knowing of course, but how does that vent the eves if the pipe is running in to a room below and then straight out through the roof. Just as a side note, I should add that it's an open loft space that has been converted. So stairs up in to the loft so it's always open. No loft hatch.

Hey John, Thanks for the reply. That's actually a job for me to do, get all the old insulation out and put all new in. There should be a gap towards the end of the eves for the air to flow up from outside right? I assume the damp air should be going out through the roof vents installed, they cut holes in the felt so they're open?

Hi all, I'm really hoping someone can give me some advice. We had a new roof installed around 3 months ago and we have massive condensation issues. Our loft room has been converted by previous owners so it's a big open space with cupboards that go in to the eves which are all open. The new roof had all new non breathable felt used (roofer saying this is current building regs for man made slate, using GuardeShield) It's had 3 roof vents on the back (an additional 2 installed recently because of the issue) and I believe 3-4 on the front. We decided to keep all the old ridges as it fits the style of the houses around here and looks better so these have been cemented back on. The tenement on the back of the house is using a dry ridge system. I decided to check in the eves one evening when we had the last big storm and was amazed to see the amount of condensation in the back of the eves. Timbers soaking wet. Pictures for reference. It looks like the condensation runs all the way up the roof ridge line. It turns out there is a plastic vapour barrier there from when the last roof was put on, no idea how long ago that was. Roofer saying this could potentially be the issue or the fact the old ridges have been cemented back on. I'm a little unsure on that simply as every single house you see has cemented ridges but hey, I'm no roofer. Any advice would be greatly appreciated as I'm kind of at a loss as to what to do at the moment. Thanks
