Building a roof deck: Need help!

Is there a certain way you have to install or build a deck that will be on a flat roof ?

Um, yes. But your question is pretty vague... you will need to provide more details such as what your flat roof is made of. EPDM? torch down? At any rate, nothing can be fastened through the roof or it will leak. Nothing can block the drainage of the roof or it will be more likely to leak.

You will need several anchor points for the deck that are tied into the roof framing and roofing membrane, which a roofer will then need to waterproof. An architect should specify how this is to be done as you will likely need a permit for such an addition.

Also, how much height do you have to work with, and will the deck need a railing or is there a preexisting railing? Is there a door that will be used to access this deck from the inside? Distance from the door threshold to the flat roof?
