Is there a roofers forum?

[littlespark]

For the 3rd time in 3 years since my extension was built, I’ve got water stains on my ceiling. Only happens when it’s really hard rain, and today it’s absolutely p**sing down.
Spoken to main contractor who did the job. Reply is always phone the roofer. Done that last time and he had resealed it a couple of times.
Water still comes through the same bit of ceiling.

That’s the living room ceiling. It’s also coming in through the porch.

Kind of soul destroying when you spend a lot of money on something and it’s never right. I’m now hoping it doesn’t burst through and wreck the new sofa

put a small hole in the ceiling where it's wet and let any collected water drain into a bucket if you suspect that there may be a puddle on top of the ceiling.

Is it a flat roof?

 

[buzzlightyear]

reason for that ,either there is no pitch or water is getting under the lead flashing .
get on the roof and look at it .

Can you get to above the ceiling?

isn't it up to the main contractor to phone the roofer? also, you're probably due a major repair instead of a patch up at this stage. was the work guaranteed? if its not being fixed properly you're within your rights to get someone else to fix it and send them the bill. of course getting the money off them would be a whole other story

As others have asked is it a flat or a pitched roof? Do you know where it's getting in? That can be difficult to discern as water often runs about internally before coming through exactly where your new sofa is

Any pictures of the external structure?

If it only happens in very heavy rain maybe the gutters are overflowing and it's getting in under a soffit, or there's dodgy flashing on a flat roof - flat roofs always leak! Or if it's only when it's windy as well, maybe water is being blown up under flashing not properly dressed to tiles.

If there is flashing check it's proper Code 4 product, not the sticky-backed cr@p which always rips or falls off after a few years.

Initial thoughts. I hate roofing.

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

As others have said ,
(wind blown under flashing - no longer sealed..)
Speculation need pics !

No it's not: that's an excellent piece of advice. If it's moisture-resistant foil-backed plasterboard there may be Lake Victoria up there, which needs draining off before the whole ceiling suddenly crashes down.

Are we looking at an old external cavity wall that's been knocked through to your extension? If so, I'd say good chance the leak is coming from higher up, main roof rather than extension, and is dripping down the cavity. May have been there for years but never showed up till you extended, as was dripping down to the bottom of the cavity.

Builder would of been a bit naughty then, not putting cavity trays in.

I’ll post other photos when I’m home.

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
