Thanks what headlap would I need for a 40-45 degree roof?
Please refer to the headlap table.

How many slates does it take to cover per m2
The number of slates per m2 will change depending on the pitch of the roof
Here is a table showing the coverage at various headlaps, the lower headlaps will be for steeper pitched roofs.

Hi there... Please advise what the spec for battens and counter batten with the Brazilian roof slate would be... can they be used at 25 degree pitch? Many thanks
The size of the batten and the batten gauge are both dictated by both the headlap (how much overlap the slates have) and the rafter spacing.
Generally speaking natural slates can achieve a pitch of 22.5 degrees.
