How do you properly build a deck on a flat(-ish) roof?
I live in a home in NJ (4A/5A climate zone border) with a 3rd floor wooden deck over a a slightly pitched flat roof with conditioned living space below it. This deck was built about 7 or 8 years ago, and is supported by 4×4 posts which are going through the roof and on top of the rafters on the second floor. The ceiling on the second floor is leaking now, and I’m pretty sure the deck isn’t too safe.
But I do enjoy the deck, and I’m hoping to do some renovations soon and wanted to ask everyone on here what is the best way to build a rooftop deck that allows the building envelope to remain intact, but is still supported properly. I know how to make the roof well insulated, I know how to properly support the deck, but how does I combine the two?
Any help would be appreciated, and thank you in advance.
