Would like to know how to create the 5mm slot i seem to require, at the ridge for the airflow through my soon to be built roof.
It will be Cembrit Jutland slates, sitting on 175mm insulation, between my 200mm rafters.
Ventilation of 25mm needed, so i will counter batten.
I can have grilles in my soffits, but how do i get the flow out at the top?
This is a mono pitch "lean to" roof, coming up against my rear wall. Warm roof, as it will be my sloping ceiling.
Thanks.
