I have to get retrospective Building Control approval for a roof which has
had its slates replaced by heavier tiles. I understand I need to fit an
inverted 'A' frame which I want to do my self (to save £350+). Whilst I
understand how to make and fit the diagonals of the A frame, to the purlins,
I don't have any info on the horizontal beam/s of the A frame (which will
link the two purlins) e.g. what diameter bolts/how many/is it two beams or
just one? Does anyone have a spec or drawing or could describe it.
