Hi

Hope someone can help with this! We have a damp patch that is slowly spreading from our ceiling and down the wall in an upstairs bedroom. The wall/ ceiling dont feel damp. (Can't add picture as the file is apparently too big and I only have an iPad).

We had a new roof in June and new plaster / damp proof in June last year. Yesterday I had a guy come look at the guttering / facias and soffits. He said he "it's a weird one" and couldn't dfinately pinpoint the problem was but that some of our fascia and soffit was rotten and it could be that.

I don't want to throw any more money at this without knowing what's going on. The patch started very small and has grown in size over the past couple of years. It has to be solved but I'm really at a loss at what to look at next. There's no pipes in that area and the damp remains and grows even in the driest of weathers. It's doing my nut!!

it could be insulation close to the eaves, or it could be blocking ventilation to that area, causing condensation

What's the ventilation like in that room?

Also, if you want to attach a photo of the problem using your iPad, you could try taking a screenshot of the photo. It will be a much smaller file size.
