A leak from somewhere in the roof it seems.

Never heard of a lead slate outlet ? look at http://www.obrienleadfab.co.uk/lead-roof-outlets.php

As the leak is on and above the party wall with the neighbour it is a raving certainty that the said other party has an involvement, and as mentioned the outlet and RWP serves both properties.

The pipe will not enter the roof space but drops to the hopper through the eaves behind the fascia board, it will be the flashing to this outlet around the slates that is letting rain soak the party wall behind. If the neighbour has a close investigation he will no doubt have same dampness his side.

When I read your earlier post it did not occur to me that you were talking about an outlet. Sorry for my misunderstanding.
The outlet in your link is for a flat roof.
I think that there will be a chute formed from rolled lead - same effect as a preformed outlet.
It is difficult to know where leaks originate but easy to see where they finish. You might be right but I'm not convinced, given what has been done to the underside of the slates, that it is definitely a case where any leadwork has failed.
I hope that the OP lets us know the outcome for future reference.

I must ask did you have a full structure survey carried out or did you save a few Quid and only have a BS survey done?

Well, I had the Homebuyers level survey on my house I have just bought and wasted my money.....

Reason being the blimmin' surveyor didn't spot the fact that there was damp lurking underneath my upvc fascia boards waiting to get inside the house (courtesy of previous owner having had cowboys replacing those fascia boards and what wood there was:cool: underneath those fascia boards was pretty sodden at some points and starting to rot).

You just never know what might be underneath nice new-looking upvc fascia boards and it could be some wet edges to timbers.

Well, that's what was found on mine when I got a firm in to improve matters and found that everything had to go...:mad:

Anyways....on another thought...chimneys can cause damp patches elsewhere. There is currently a fair-size patch (historic I think) on a ceiling in this house and its bang in line with the chimneys on this house. That would fit with the guys who have just done the upvc fascias on this house telling me that water had been coming in from one of my chimneys and running down and rotting some wood underneath previous fascia boards on this house.

I think he highlights very nicely the benefits of paying for a full structural survey given the OP didn't and I suspect he and his wife have stressed over this and will have to pay to correct it and would now accept the 'cheap' survey option was a poor choice....? Would they do the same again if they could turn back the clock??

It might not help them directly but it's a lesson learned if they move again or for others reading this and contemplating the cheap option because 'the house looks good'!

Why the need to make an issue of someone making a valid post?? A bit pathetic really.

Utter tosh

This post is for help on a roof , it doesnt help being preached to about surveys after the event ESPECIALLY when there isnt a gurantee a full survey would have unveiled the issue anyway!

It cannot be denied that for anyone contemplating buying a house the purchase of a moisture meter (Amazon £15.96) is a good move , even if you are having a survey of some sort done. You just have to front to not worry about the owners feelings when you stick holes in his walls and woodwork.

and your posts have helped resolve his plight how??

I can't see any useful advice or anything from you here on the thread .... just, well 'utter tosh' pulling people up for contributing with some valid points.

At least bring to the fore the risks of spending quarter of a million on something not knowing what problems may be lurking MAY help SOMEONE avoid the same stress and hassle the OP has!

If the survey missed it, he'd have some form of redress.

blah blah blah , shall we just both leave it , the op`s thread is already suffering from too much unhelpful waffle

Maybe we should've gone for the structural survey, maybe it wouldn't have been worth the extra money. Who knows. What's done is done. If we want to discuss structural surveys though can someone please create a new thread & discuss it there as i just want my roof fixed. Thanks.

Had the damp survey bloke come out to look at the damp in the living room that i discussed here. Oh yes, it's damp alright.

I wont discuss the living room in this thread as this is about a roof, so onto that...

I asked him to spare a few minutes & assess the bedroom. He agreed it's most certainly a leak from above. He took readings which said - WET THROUGH.

Around the patch is dry, but the patch is wet. He asked if he could stab the wooden section in the roof which is wet (you can see yellowing on the paper on the roof). No problem.
He said something about mould at 30% & his readings were 60%. He said the timber was WET!

He couldn't say whether the timber was goosed or not, but he said what we all know - someone needs to check it out. He said not to be conned by anyone saying the roof needs to be redone & £1000s thrown at. If the wood is not rotten then once the roof is sorted it will dry out & regain its strength but if it's on its way out or out already then it needs replacing too.

He had a look outside & said it may well be the hopper but suspects lead.



Once he'd gone i had a look around the street & noticed something. Now i'm no roofer & know sod all about them but i was trying to look for differences between ours & others on the street & i noticed 2 differences.

#1 - the ridge on top of the triangle on ours is a bit squint. It looks cemented on, but most others on the street are perfectly straight. Note i say - most, so not all. I suspect this is nothing to do with anything??

#2 - this is the one i'm wondering if its the cause or not...
...when you look at the valley between other houses on the street you can see the lead in ALL of the cases is sort of folded over the fascia board, so that rain can run down it & will just go down the hopper....
...however on our house (& neighbour) the lead is NOT folded over the fascia. It sort of just lays flat & there appears a gap underneath it & above the hopper. I don't know what's there in this gap as i can't see too well, but i wonder if rain driving at that side of the house can get under it (& cause this problem).

I took some photos on my phone which are quite poor. I'll get better shots in daylight with a better camera.

Our house:


Notice the flashing just sort of finishes, flat & isn't folded over the fascia like it is on every other house on the street.

Can't see much in this photo but i'll upload it anyway - another house on the street....

Yes, I'd be thinking of raising the hopper into the fascia with a dogleg to connect to downpipe and a lead shute into the hopper. As things stands, water can run off the roof then any breeze can blow it onto soffit, rendering and airbrick. Those cables look ideally placed to pull water into the wall too. Def. a bodge job.

You need to be thinking about spending some ££ on that roof IMHO

anotherbaldrick

You need a man and a ladder to get up and have a good look at that, trying to diagnose it from down below is futile.

Ah so that's what soffit strips are used for. Always wondered what they were at work.

Your last comment - about spending some ££, what would you have in mind? I understand you could be way off the mark because you've only got my photos & descriptions to go off, but on that, what would you be thinking?

We're thinking long term - a re-roof & modernise it all with felt etc. However in the immediate term we simply cannot afford that. Not with the damp in the living room getting sorted as well. Not a chance.

At the moment it's all we can do until we can get a man with a ladder. Like i say, i was just trying to see from ground level if i could spot any difference between our house & other houses on the street. From ground level that was the only difference. No other house on the street has lead flashing that doesn't tuck over their fascia boards - all other peoples does.
