Awful job, This is exactly why i use a proper roofer to to the roof work. The nibs need grinding off on the tiles. If they do not sit back down the vacuum will just suck water up into the roof.

Vacuum? Are you suggesting a roof is pretty much air-tight in places?

No, when the misses is hoovering out the loft at the same time as its raining.. :yes:

I'd agree that the overlap looks quite small and some of them are up quite a way (picture 15 for example), driving rain will fly up there, eventually rotting the roofing felt away.

Doesn't look like a top job to be honest but there's plenty about like it, only time will tell how they all fair up over a few years!

In this picture there was no need to grind the back of the tile as it sat quite flat and would not cause a problem with water ingress or wind chatter.

In this picture the back of the tile had to be ground out a little, to allow the tile to sit flat.
By rights, your system should have failed building regs (the new part C, preparation and resistance to contaminates and moisture) but as there was no site visit how would building control know?
Also you have two panels at the top in your photo's which are clamped on the short side, this can invalidate the warranty on some panels due to fiscal loadings. You would need to check with the panel manufacturer on this.
I am not too keen on your panel clamps either (just my opinion), but it looks like it is a standard kit bought from your panel company.

I hope this helps

With double romans we have been using an adjustable bracket which can be adjusted to sit right down on the tile(but not sitting tight to them), then we have been grinding the lower nibs off so the tiles fit virtually flush, you have two problems from what I see of the pictures, wrong hooks and no grindy.
I can understand the ones nearest the ridge not being ground out as they obviously didn't want to disturb the ridge tiles and flashings by the chimney.
Is it worth withholding money? possibly, but would it not be better to get them back to rectify the job ( unless you have already asked and they fobbed you off!)

Many do, but this is another reason why not to fit too close to the ridge.

German quality, but maybe not installed to German standards.

Another one buying the myth that Germans are so much more disciplined, efficient and work to higher standards than us?

I think as has been suggested the tiles couldn't be removed close to the ridge (or the edge) without disturbing the concrete settings. Oter than that the nibs should be ground off to allow the tile to sit down. it won't go completely flush but certainly better than these. Removing the nibs does not weaken the tile at all, although grinding the actual body of the tile may, especially if it's ground out as much as one of the previous photos to fit conduit through!

I cant see why that tile should be kicked up?????

Are you sure they did it?

sambotc · Jan 28, 2012

I think the tile to the left, directly below the chimney stack, has not been put back properly and the rear lug is resting on the batton, so the back is up, which is pushing the tile in question up?

the ridge looks a bit dodgy to me if i was installing it that close so that i was forcing the ridge tile up i'd of knocked it off and re-cemented it. just moving it a little bit can damage the cement. pros and cons of grinding the tile neater fit, versus weakening the tile. i normally grind within reason. yours don't stick up too much seen worst.. i'd want to know what is happening between the chimney and the top panels. whether the flashing is still strong enough.

Doesnt look that bad - perhaps you should mention it to them regardless and go from there
