Oops sorry yes it was Datarebal who suggested arranging the new tiles together vertically, thank you 
So this is how things went (in answer to DAZB's Q about prices):
1. Initially got him in with the water leaking from the soffit on the outhouse. The old felt wasn’t nicely overlapping into the gutter as it was slightly short and had fallen ‘behind’ the eaves. So we addressed the following things: installed eave protection trays, replace rotted battens in first row of tiles. At the same time he redid the gutters and two leaky downpipes on that outhouse. He also installed a black fascia on the wooden eaves to protect it from rotting. Length was about 10 meters. Total £2600.
(In addition to all this he did some work in the main house for missing roof tiles and reducing&repointing two small chimney stacks, fix 3 leaky gutter joins and replace a leaky downpipe = £2200.
He also repointed the ridge tiles on the main house about 40 of them = £2200.
Installed eave protection trays on 3 sides of the main house =£750.
“Re-cotton” of the mineral felt flat roof on my extension=£750)
2. Then it rained that weekend and I realised water was STILL leaking from the soffit on the out house. So the eaves protection trays in point 1 hadn’t worked to solve the leak and it was clear that water was somehow getting under the felt somehow. He lifted a tile on the 10th row and said
“yeah I can see water on the felt. I can refelt and rebatten the last three rows of tiles for £4200.”
And I said:
“But if you’re seeing water under the tile on the 10th row up surely just replacing the felt on the first 3 rows isn’t enough? What if it’s getting under the felt above the third row somewhere? And if it IS then I’d have wasted £4200 getting just the first three rows done. Another roofer has given me a quote of £7K to do a whole entire new mineral felt roof on a new plywood base and maybe I should just do that and forget tiles completely. Because ideally water shouldn’t be reaching the felt at all, right?”
He then came back and said there was probably a tear in the felt somewhere so he would refelt, rebatten, replace any broken tiles for the whole outhouse roof for the £4200. I told him to go ahead with this. I told him that when he had lifted the old tiles&battens&felt that if he thought there was any opportunity to do work to help level the roof better then we should look into doing it at extra cost to me. During the process he found the dropped joist I mentioned and that was the £750 extra to lift and bolt into place. I felt it was expensive just for one bolt but I’d come this far and didn’t want him to reroof over a loose joist! This is the re-roof that we are talking about where he’s used replacement tiles that seem to be too big.
For info here are some other repairs he also did around the property:
3. He redid the repointing on the lead flashing where my extension flat roof joins the main house using something called “CT1” at “£20 a tube”. Also fixed some loose lifted mineral felt. Added a gutter downpipe to help the extension gutters drain better . =£2300.
4. Inside the outhouse there were some very big vertical cracks in the plaster in several places. He said he had to “grind out and add pins to pull together”. Also repointing around the two doorways and thresholds on the outhouse. =£3600.
5. I have a single brick built single garage with an apex tiled roof. So he replaced missing 20 roof tiles, repointed the ridge tiles, replaced old broken metal gutter and down pipe on one side with new plastic ones. Installed black fascia on one side. Said he was going to install some lead in the bottom corner to prevent water ingress but looks like he’s just used flashband instead. What I said “I thought you were going to use lead?” He said “I’ve used something more expensive than lead, it has a bitumen backing so it will last longer than lead”. But it still looks like flashband to me! =£4600
It was after all this I climbed on the outhouse roof and noticed the tiles weren’t interlocking and the overhang which meant I wasn't happy with the outcome from the work done in point 2 (the £4200+£750 work).
He was about to start a £9K piece of work to repoint around my main house brick. But I felt it was too much and after seeing everyone’s reaction to this post I put a halt to it and started to question him more about why the outhouse tiles weren’t interlocking properly.
He's angry at me now for suggesting the outhouse roof problems are due to him using a larger tile size. He’s picked up his ladders while I was at work today and removed his business board from the front of my house.
