Cold Roof Skylight ventilation

[firapara]

Hi guys,

Are there any special considerations when installing a skylight on a cold flat roof?

Is it just building an upstand, insulating it between the timbers and covering with plasterboard?

Or do I need to do anything else for the ventilation purposes?

Thanks

Will the upstand interfere with the normal flow of air?
