Materials for new Pitched Roof

[Nitell]

Hello guys

I am building a garage. Trusses are installed.

I have been given some left over material, (1) solid insulation board, (2) breathable membrane.

Can someone please advise what I need to get in order to have material onsite for a builder when they give me a quote for labour?.

Thank you.
