Our 100-year-old tiled roof has no underfelt and a few tiles are starting to slip, so I guess it's time to re-roof with new breathable felt and battens, using as many original tiles as possible to avoid losing its character.
The old tiles seem generally sound; they have two holes, but they have no nibs on the back. It's hard to see how they are attached by looking from inside the loft, or even take a photo, as a flat roof extension makes access very difficult - but from a distance it almost looks as if they are attached by something like split pins, though I may be completely wrong.
Could someone please explain exactly how plain tiles were normally fixed in place at that time?
Will a roofer need to alter his technique in any way to comply with current building regs for ventilation and so on?
Many thanks for your advice,
Alec.
