What works need to be done before the cladding can be installed?

For wall cladding applications we require the windows and/or shrouds to be installed.
Roofing needs to be finished and flashed up to the top of the top plate for us to cap over if this is included in our scope of work.
If the cladding is installed on the first floor walls over some lower roof areas these need to be flashed up and finished by others prior to starting.
