Title

victorian, unfelted roof?

Hi, got Victorian property, original Welsh slate roof onto battens with no felt/underlay. roof is sound, breathing well and no plans to re- roof, however bathroom below has no extraction and has condensation problems. Would an extraction lapvent, taking bathroom air, work if installed within its own felt 'cocoon' under slates - or just on its own?

Advice appreciated; looks a great solution and hoping it's the way forward for us!
