Is there a roofers forum?

[davesparks]

Thanks for that, Dave!
Just seems a curious, random piece of advice though

The OP said they were hoping it didn't burst through and wreck the new sofa, so it appeared they hadn't worked out how to drain the water from the ceiling to prevent that happening.

The leak could be anywhere. I had something like this where the water ran along the rsj from the side wall until it hit something and dripped down

Looking at the pic it looks like it is in the RSJ boxing.
You are correct though , it could be travelling from anywhere.

does appear it's coming down cavity from main roof. gutters blocked by moss etc.???? we get a lot of that. has to be cleared every 12 months.

We’ve got water entering our chimney and dripping on the stop plate. My mate who fitted the flue took a look a while back and is happy to look again.

As our extension is over 3 years old, I’ve rung a local roofer I know and will see what he says.

If it costs me a few quid to have the job fixed properly, I’m happy with that

Wow, I didn't know we had so many roofers on this forum.

A little bit of background before I take more photos.
The house is timber frame, approx. 11 years old. 3 years ago we had an extension built which doubled the size of that particular room and added a porch at the front door.
Sloped roof, correct angle and proper roof tiles.
There is an RSJ in there. A window was removed, the hole made bigger.
The 2 wet patches you can see on the boxing are either side of the bedroom window above.
The roofer says the lead flashing is close to the underside of the stone sill of the window and water is creeping over the lead and working its way in.
He says it only happens with driving rain? Yes... but its Scotland... the rain is always driving. That's no excuse.
This doesn't explain the water marks in the porch, which was the old front door, just the old framing taken out, wall boarded over and an interior door and frame put in. The old front door was moved to the new front wall.
There is a window above this leak as well, but its much higher than the lead flashing.
On another note. The bedroom window above is now suffering from excessive condensation, causing black mould on the white sealant around the UPVC window.
It really only started when the extension was built.
Could this be connected to a lack of ventilation in the new roofspace above the extension?

Did you have a nice draughty back-door before modern extension was fitted?
(Do you have any upstairs en-suites sitting on weirdly placed RSJs ! -
Looking for excuse to blame another dept )

there was a roofers forum but they all fell off the scaffold.

proper Scousers.

This is a photo from the porch.
I’m not going outside again to take a photo. Still raining

My wife now wants all the tiles off to check the woodwork isn’t rotten underneath.
I’ll have to look out the paperwork regarding a warranty, but would it already have 10 years the same as NHBC?

 

[telectrix]

watch

 

[ruston]

Is the wind blowing on to that porch now?

I would be loathe to do investigatory work of such a nature at this stage. The wood will in no way be rotten any timber in there will be C24 structural grade and treated it would take several years for any rot to appear. I would talk with your insurers about it first and see what advice they offer and whether they would be prepared to meet costs of the leak as you should be insured for that. Clearly some fine detail work has been neglected or it could be the leak was present under the house builders aegis or poor workmanship to put it in common parlance.
