Low Pitched slate roof is leaking - Possible solutions

[noseall]

On which layer would you place breathable membrane?

Directly beneath the plasterboard.

This isn't a new method but not that common. If the counter batten is felted over then the areas between take the majority of water.
I'm not impressed by the idea though.
Felt it, Metal it, or if you can managed 10 degrees - Decra

Lol. Is that where you put them when you tile a roof?

The thing is, the OP wants a slate roof.

It's a flatty, anything other than a proper flat roof finish is a bodge.

Same place as of you where tiling the roof.

You don't do much conservation work then?

 

[freddiemercurystwin]

You mean fixing poorly detailed or constructed properties?

 

[^woody^]

No, I mean making things which have been ok for centuries, and which have suddenly become not ok because of some regulation or other, OK again.

It was a cock up initially I didn't know anything about minimum pitch and builder never advised. This is one of the solutions I'm looking at a flat roof would look out of sorts in this area

Zinc or lead standing seam for example rarely looks out of place IMO.

Standing seam looks great on a B&Q

And very common on many older properties, I guess you only get to see the felt ones though.

Freddymercury do you think will leak what im planning to do

 

[freddiemercurystwin]

Probably, you're relying on felt which is gonna be penetrated hundreds of times.
