Hello
I have a slate roof that I am wanting to re slate. Its a lean to and was a hay loft that I re slated about 35 years ago but is beginning to leak.
Its formed from 9x3" timbers ( rafters? )
I live in an exposed site and would like to sark straight on to the 9x3s with 15mm osb, counter batten it, membrane, then laths and slates.
My problem is there is 2" of insulation with a ceiling below the top of the 9x3s. How could I ventilate this space as It is a cold roof. I can fit soffit vents to the bottom of the roof but the top where it butts up the the stone wall of the house is a problem.
Any ideas please
