Its mad, but probably not one-off-mad, I fear

Lust can be (is almost always) unrequited.

Lusting after a Bosch ... what's new about a Bosch wanting a Bosch? ?

Hmmm, looked at YT in relation to leak tracing and thermal cameras - it seems that it's not such a silly idea at all. January sales : I feel another tool beconing ... Anyone got a recommendation about thermal imaging cameras?

Our ridge is dry. Ridge tiles double nailed ( yes, nailed)..... Under those tiles, there's a corrugated flexible ridge membrane. I have mislead you all about the roof build up: On top of the joists is a wooden batten that runs along the joists (25mm) [There's a 25mm gap between the top of the insulation and the top of the joists - 50mm gap in all] The there's the felt - with slightly slack trough to allow water to run to the centre of the gap between the joists On top of that is the metal batten which holds the metal formers which hold the ceramic tiles. I was incredulous when on our Piggery, a chippy foamed the tiles in place : and appropriately professionally cross. "How's the air going to circulate round the roof space?" I kid you not, this was the answer ..... "We don't worry about that oop 'ere . We allus duz that 'ere......"

Yes Peter. So my theory is that there are two sources: a small crack in the tiles (rain), a rip or two in the felt, AND under-tile condensate taking unfair advantage of the holes. Thanks for the thought @epsilonGreedy, but no. The drip is localised to the edges of two sheets of PB. Doesn't mean that that's the source though. Does anyone think that a thermal imager might offer a clue to trace the leak back to it's source? There will be a temperature difference won't there..... idea?

Yes. The temperature of the air mass - from the south west warm, but wet - so little or no condensate. Freezing / very cold north wind promotes condensation ... drips I agree: thats what worries me. Nowt for it but to get up there, pull some tiles off and have a look see. Thats one thing that's bloody brilliant about self building. I know exactly what to look for, and I can get on with it virtually on my own. Photos to follow. Ian

Here's one to keep our @Russell griffiths happy, and to help reduce @SteamyTea's Schadenfreudesucht. Please could you review my thinking, and see if I've missed something. Thanks. Two years ago, just after the roof was tiled with Nulock cermaic tiles, a bit of a hooley blew up: long story short it blew some scaffolding planks off the scaff and onto the roof. Live and learn. Next time scaff plank clips. ? Here's part of what the storm did. and here's how I repaired it The photos were taken when the storm was still pretty full-on: I was clipped to the scaffolding with a full harness. Nulok is easy to replace though - and I was keen to get the job done to prevent further damage. Fast forward two years. Drip, drip...... WTF !!! how's that happened then? Dry up to now why, how, bugger it ... Debbie looked at me and didn't say If ya can't take a joke, don't self build . (my signature line) There's not much of a drip. In the recent South Westerly storm that knocked us all on our heels, (warm wind), not a drop came through the roof - or perhaps better put, not enough water leaked in the roof to come through the roof build up . When its frozen outside, there's no drip. When there's cold northerly rain, there is a drip. The roof build up is; Tiles Metal Batten Felt Counterbatten 200mm insulation (between joists) 100mm underboarding insulation batten 12.5mm PB Neither was there a drip when it froze ... this morning - freezing - no drip before we popped out to the shops, but there was a drip when we got back. Temperature had risen by 5 degrees...... No rain - but there was ice on the roof when we left, - the roof was dry when we got back. As I write this, the damp patch has all but disappeared in the PB. There is no roof space, so I cant see the exposed underside of the roof from inside. Heres a cross section - Why did it happen now? A bit of head-scratching and came up with the following - what have I missed? The repair to the tiles was done under pressure: it was quite dangerous - windy enough to be fully harnessed and clipped on. The repair to the tiles took about 15 minutes. Nulok is very easy indeed to replace - throw the broken tiles off the roof, slide in a new one. They simply clip in. What I did NOT DO was inspect the underlying felt because I was worried about being blown off the roof. I bet I simply missed a small rip or two in the felt...... If thats correct, given sufficient temperature contrast, there would be condensation on the bottom of the tiles. And maybe there's a bit of ponding on the felt... and the water makes its way through the small rip. And because its small hole, it takes ages to show up. Maybe it took that long to trickle through over 300mm of roof build up. Anyway, have I missed something? Constructive comments welcome. @PeterStarck - what do you think? (I ask becaue you have Nulok) Tomorrow, scaff goes up, fetch a roof ladder (although you can walk on Nulok tiles) and then a wait until there's a long enough weather window to whip some tiles off to look-see. Bye bye 2020. Lets hope 2021 is better eh?

I bet Ed has ( @Construction Channel ) .... Wake up Ed. Baby keeping you up at night .... ? ?

We hear more noise from water running through the metal guttering than from the roof. Mind I'm writing this in a very heavy hail shower - we can hear that just fine.

Well done Pete. Lots of hard work there, and doubtless more to come. Your window cleaner will be smiling too.

Yes, properly in. One bedroom needs a lot more work - no plaster yet - and you can feel the cold streaming in. Durisol is 86% fresh air after all. Vistors are offered a paint brush on entry ....? VAT return beckons

Ooooffffff.... that had passed me by. Reference please if its not to onerous a job. Thanks. Ian

Excellent news Dave. After five years of graft and grind, you can be proud of all you have jointly achieved: prouder than those who can just sign a cheque and move in. That word FINISHED It's a weazle word innit ? Will we ever think of the job as truly finished? I suspect not. I for one will have to find something as intensely absorbing and - frankly - as uncomfortable as the demands of a self-build. Fitting batteries soon, maybe? But then again, to you that's nowt is it?

Planning Officers have thick skins: have to have. Rollo's dad (yes, Rollo of this Parish) - very large local land owner (and estate agent) took me aside one evening in the pub and said "The biggest mistake almost everyone makes is to assume that they have rights over the land they can see, as well as the land they own" Its building use that matters, nothing else. And what of Rollo? Working as a builder's mate. Top lad. Starting at the bottom.

Yes. An experienced Planning Officer will simply ignore any comments which are deemed non- material. To lighten your mood, have a read of this post.

You haven't wasted six months of your life if you walk away. You have a wealth of experience that nobody can take away from you now. By that, perhaps Russ meant be persistent.

We are a 2 person house (in a 2 bedroom house) using a 13 person tank. The unit is working fine. We plan to connect another 4 bedroom house to the same tank in the new year. The tank will more than cope with two houses full of guests. Fat chance this year.

Biopure 3 (2.7m deep hole I seem to remember )

I have a BioPure . Whenever I had a question, it was always promptly answered by the manufacturers. Here's their contact page I very much doubt whether water softner in domestic quantities will do anything to damage or slow down the general oxidation process. If you are fitting the same system we have, the oxygenation process is aided by the air pump: the trickle (so called) of air from the pump causes a 'full-rolling-boil' type action in the tank. Its very strong indeed

Take very great care before alleging fraud. Be certain of the facts. Build an unchallengable evidence base.

Is there any way of checking the date of the map they have used? It might well be - probably is - out of date. In which case ........

Dave - why are you writing sentences like that? Betcha it'll be less than an hour before @TestUserDoNotDeletePlease gets his teeth into it.....
