Yes definitely under the "felt" There's no way to solve the problem quickly easily and correctly!

So it seems firring strips are a general term for tapered timber. Sprockets are usually sistered to the side of the rafter, but the end result is the same. A better explanation is here: http://www.roofconsult.co.uk/articles/tiling/tips91.htm

I should have said "firring strips" bloody autocorrect. A tilting fillet is similar, but usually just order one course at the eaves and can cause a sudden change in pitch. A tilting fillet will serve a similar function to the wooden shims you tried, but will still mean the tiles are too flat. A firring strip extends up 4 battens usually which is why I said 400mm and changes the pitch gradually. A rule of thumb I always work to is if I want to gain 1mm eaves height, the firring strip should be at least 8-10mm, but always at least 4 courses to make it gradual. I think firring strips are also known as sprockets. I will try and find a proper technical explanation and drawing link

Fitting strips should have been fitted to the rafters when it was built. Approx 400mm long tapering from 40mm at the fascia to nothing. You can retrofit, but would mean stripping a lot to make it match.

Are the eaves tiles going into a parapet gutter or a traditional fascia? I'm not clear where the fascia is on your pics

A photo will tell 1000 words

The photo is of a Clearview stove. I think pioneer 500. The optimum burn on that thermometer is 140-300c approx. It generally sits around 150-200, but can get to 300c if you really load it and burn it hard. I have a Dunsley Yorkshire with back boiler and it's not as easy to light or control and doesn't keep as clear a screen as the Clearview,but does run at similar temps.

The chances of getting the 5 tiles off the wall without breaking is very slim. The chances of getting replacement matching tiles is slim to none The damage that may be caused insodoing is unknown. £1000 is steep, but it could lead to having to retile a much bigger area

k = 0.24W/m°C for 3.6 N. k = 0.28W/m°C for 7.3 N So might be worth running the calcs for the difference

3mm is better with flooring especially larger tiles, unless you are trying to line up with the wall tiles

It's not a job to undertake lightly. It will cost £60 per sq m for it to be renovated by a professional. Given the change in height you may be wise to stick s thich underlay and carpet over!

How many tiles are loose?

Why not ask them where they are working for the next two weeks and have a look at their work?

Sorry should have read fakespot https://www.fakespot.com It checks to see if it thinks the reviews are fake, which you get a lot of with crap Chinese imports on Amazon. Just copy the website you are looking at and it gives you a confidence level about the review authenticity.

35mm is too thin. Check that it is actually 100mm as they often quote a nominal size before planing.

For the money you spend on a surveyor you could get that takes out and repointed so it looks more seamless. I presume that movement hasn't occured during your ownership. What happened when you bought the house?

I don't know exactly how, but it happened with my oil boiler after draining it down. There may be a sensor measuring flow of water which tells it to turn off if there is insufficient. It took a £60 call out fee and 3 days of repeated radiator bleeding to get it running smoothly.

It might be worth checking the rads to make sure they are well bled, which may be an issue if you've recently flushed it as air could cause it to cut out.

So you are arguing over whether the builder will paint a coat of sealant on the interior ply? I think the wording "to receive" makes it look like it is specifying a grade of ply suitable for further finishing by others - i.e not a simple sheathing ply I would say yes it should have prompted clarification from the builder, but more importantly it should have prompted more detail from you. The cost of mopping the interior ply with watered down PVA might be vastly different from 2 coats of Osmo oil

Reviews are genuine according to GameSpot. At that price it looks like it's worth a punt

They will build you anything you want. Factory built insulation will probably be better than something you do on site

Same experience as @dpmiller
