Unexplained Damp Patch Spreading From Ceiling Down Wall in Upstairs Bedroom

Postby Pansypots » Thu Oct 27, 2016 6:30 am


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!!

Simply Build It

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

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.
