    The bay window needs a new roof as the existing is shot.
    check the roof tiles have enough oversail into the gutter as you have new upvc fascias.

    New felt for sure, decking may need renewed, upgrade insulation if required.

    Do you think this roof is causing the damp problems in the bedroom as shown in the picture? Thanks

    as above - both bay roofs are shot.
    and both sets of guttering need stripping and re-fixing to adequate falls.
    maybe the neighbour changes guttering or transitions to yours at a central running outlet?

    the damp on the lower bay panel - when the bay roof is off (i presume the boards will also need replacing) check for moisture entering at that corner and running down to show below.
    or, maybe thats plasterboard or plaster laths showing damp that you could open up, and then look for a cause in the lower bay?
