Roof Without Felt! Help!

[Tozzy]

Hi,

I have a big problem. I have a roof without felt underneath so everytime it rains, water comes through the terrorcotta tiles (yes, TERRORcotta because they absorb water!) and as there is no felt underneath the battens, the water ends up all over the floor in the attic.

See picture (sorry it's poor quality, very dark up there):

As the roof is very big, I'm hoping for an easy way to fix instead of removing the tiles, battens, laying sheets of felt, putting everything back again. I've been thinking of putting felt underneath the rafters but of course this won't work as the water will just rot them over time.

Any ideas greatly appreciated!

There is no fix apart from new tiles or stripping off and adding an underlay, you know it in your heart don't you? There are countless roofs around the globe with no underlay but they do not leak unless the tiles have failed.

Unfortunately, I do know it in my heart But I'm still keeping my options open such as felting under the rafters and then adding additional rafters between the existing ones provided there is enough space to squeeze them in. That way, the roof would be reinforced and the tiles can stay where they are. But at the moment, I'd have to check that I'd be able to do that.

You sure the tiles are absorbing water? not condensation.

Definitely absorbing water, as this only happens when it rains and even when it's only light rain. When it's heavy, it pours in like the titanic going down. Just don't know what to do. Was really wishing for a short-cut to avoid costly and laborious work. If anyone has any ideas, please let me know asap. Would really appreciate it as I have to make a decision over the next week or so.
Thank you.
