Hubby is a very well sought after builder, and one of the things he is always surprised about, is the lack of information other builders leave out on their quotes, which leaves an opportunity to 'add things on'. His quotes basically state EVERYTHING he is going to do, and he always get's told this by clients. If your quote is not clear on what work is going to be done, that could be a worry, although it does seem to be the norm.
Agreed, I would much rather have a comprehensive quote including everything on it then a price and a brief description otherwise I end up going back and forth asking questions.
To do the work Cyberknight is asking I am assuming having never seen his house is tiles off, batons off, felt off, ridge tiles off and then redo felt bottom to top with overlaps, new batons (or existing if ok) then replace tiles bottom to top and finally redo the ridges.
If there is any lead this might need repairing/replacing as it will be mess with when lifting tiles. Any tiles broken in lifting will need replacing too.
Fascia and guttering is pretty much what it says on the tin but added complications can arise if the cladding meets a window and a new strip is needed as they are often glued onto the window frame. Fascias which are not in the best of conditions ideally need treating before overcladding to prevent rotting from the inside and consider retaining the unvented or vented fascia style so as not to cause problems with damp and condensation at a later date. Choice of guttering is interesting (black, white, square, half round, guards or not etc) and it is a skill in pitching it correctly so it drains.
I would also while the roof is off if not insulated consider adding in extra insulation.
