Can’t find the leak in my roof
Need help!
We have been battling a leak in the corner of our top floor bedroom for almost a year. We’ve had the entire (flat) roof refelted, the roofers have been back over and over and over again (at least a dozen times) to burn extra felt, silicone corners, seal gutters, everything they can do…. But we still have some damp inside.
My husband thinks at this point it could be condensation (and I read the helpful link from the post here the other day) but I’m not sure, and I just don’t know what to do next! Frustratingly the really wet weather from the winter seems to have passed – I keep telling my husband I want to wait for a biblical rainstorm to really see if it’s leaking but it’s not coming.
I think the roofers ran out of ideas long ago…
What do we do next?!

It’s difficult to see from photos. Presume this is the same corner. Before; the rotten boards and after?

There is a machine that sucks the moisture out of a room (water drips into a bucket – sorry I’m not sure what it’s called). We had serious damp in walls when we moved in caused by guttering issues that had allowed water to drip onto external wall for long period of time, after fixing the cause of issue, we used this in our house for over 1 week to dry out the walls and the issue has now been resolved!

Get yourself a dehumidifier for a week and leave it on. You can hire these for around £30-50 a week any monitor

It could be worth getting a damp specialist in. An independent one, Vs connected to any work. I did this with a very odd damp patch that kept appearing! They use cameras, so found the issue was actually leaking through the bathroom tiles, and the worst spots weren’t necessarily where it was showing on the wall. Easily fixed, and saved a lot of frustration

Has the outside been repointed?
We had a similar issue (moved in 8 months ago) and we were given 2 options, repointing or cladding. We’ve cladded the whole house and the water coming through the walls has stopped.
(We also had all the roofs re-felted before realising it was the exterior walls and not the ceiling)

I feel your pain. We have a similar leak. 3 roofers have looked. Flat roof replaced. It appears it’s only if the wind blows in a certain direction and sends it up under the tiles but there isn’t much we can do. If we seal one spot it comes in somewhere else. I’m told this is quite common?

Guttering and pointing – could be a crack somewhere in the rendering that is letting water into the general area. Close inspection up around the roofline to see if a gutter or join to the roof is possibly involved

Try a different roofer, perhaps a general builder. Hope you get a solution soon
