I want a shallow pitch slate roof on an extension but can only get about 10 degree angle.
I've read somewhere that shallow as this is can be done but needs to have "fully supported waterproof membrane" and the slates are then for aesthetics only.
Anyone shed more light on this and/or point me at where I can get a construction detail that will satisfy Building Inspector (and keep my room dry!).
Thanks.
