Roofing advice please

sweety

Have had a damp bedroom for some time and thought the roof was the problem - had many local roofers to view and ALL of them told me roof was sound for its age (house over 100 yrs old) and apart from replacing a missing tile no remedial action was required. Got bedroom replastered having assumed damp to be condensation linked and bought a dehumidifier.......all going well until damp patch reemerged and a look in the loft showed the timbers to be wet!! This is the first and only time the loft has shown any moisture, even when we had a damp bedroom, so im thinking that the recent rains/wind in a certain configuration etc might be to blame..My problem,taking all this into account, is that there is no felt beneath the roof tiles like in modern houses and i would like to ask you DIY/roof experts what my options are here,,,,,,Is there a way to fit underfelt without a reroofing bill as the roof is quite large and my resources are quite small!!
Are there any other options?

Many thanks to all who reply

not really. you can try and fit some roof vents. a fairly cheap option.
the through put of fresh air will help (rid) any condensation problem.

Is the damp concentrated in a single area in the loft? Maybe it's just a single or couple of slightly loose tiles letting in the water. This would be hard to spot unless the roofer checked every single tile, especially if it's not obviously loose.

Thanks for the replies - from being dry as a bone in the loft for 4 years it now feels damp all over and the beams are wet to the touch!!! Quite a shock to suggest gaps in tiles all over the roof!!! As the loft hatch is above the bathroom, could this be the problem ie getting xmas tree down and not fitting hatch properly? Straw clutching .......
