Cassette roof finishing?

[junglejim]

We’re having a timber frame with cassette roof erected soon. I’m going to be tackling the roofing myself and looking for information / advice / tips about layers, materials and details.

 

My understanding is that I will need to add:

1. breather membrane

2. counter batten

3. Battens

4. Tiles (Wienerberger Rivius)

 

Questions I have:

- what’s the best way to secure membrane to osb?

- do I need an extra breather membrane between batten and counter batten?

- What kind of fixings should I use to attach counter battens to roof cassette (18mm osb top layer)?

- what kind of fixings batten to counter batten?

- tips on eaves/verge details

- any sequencing tips particularly eaves

 

 lots of learning to do so any help greatly appreciated.

 Thank you in advance
