Sarking boards on roof with built in solar trays

[DannyT]

The house is currently going through planning for changes from the original design. In the meantime I’m trying to get my head around the Scottish way of doing a few things.

 

Standard traditional roof construction from what I understand is as follows,

 

Truss

Sarking boards

Breathable membrane 

State

 

Now if I’m having built in GSE solar trays, my understanding is we will have to do following,

 

Truss 

Sarking boards

breathable membrane 

Counter batten 

Tile batten

Slate

 

Is this correct? It’s okay to have the membrane flat with no slack or would membrane go on top of counter batten and be droopy?

Trying to create a thin verge without any facia so looking how to achieve this on the gable ends.

 

cheers

Effectively completely ignore the GSE instructions, they are not applicable to a sarking board roof.

 

Attach the trays direct to the sarking, through the membrane
