Vented pantiles ?

[mulberry]

Hi, my house is 100 years + old and the roof has clay pantiles which are in reasonable condition. Unfortunately the loft space is suffering from significant condensation problems, I need to introduce some ventilation via the roof tiles and the guttering edge of the roof.
Can anyone advise me please as to where I might be able to purchase vented roof tiles suited to my pantile (original) roof. Or how I might be able to resolve the problem without having to strip the roof? Thanks for comments/advise.

you probably will not get tile vents. You could use soffit or facia vents or possibly have Lead vents made to go into the tiled slopes.

Over fascia and ridge vents.

disc vents in the soffit might be easier
