How to diagnose water damage?

[tigerzen]

Hi all, my sister reports some water damage in the ceiling of the lounge room in her townhouse. I've included some photos that I hope will narrow down the problem. What you think, blocked gutters (although there aren't many trees around), or other trouble spots.

Thanks Eric, been a fair bit of rain in the last 24 hours, the ceiling is no worse, I'm still not sure that I've found the issue, although silicon is a marvellous invention.

Hi @tigerzen 

I suggest going with @Nailbag's suggestion and getting a leak detection service to come and scan your area. You'll definitely see where the water is passing through as they have various tools to see and detect water ingress.

If you need further assistance, please let us know.
