What to do with my flat roof garage?

I have a (50 foot) long Ranch style home with a very mild pitched roof. I am getting the roof done in a month. I am not thrilled in replacing my flat barely pitched (25' SQ. ) attached Garage! ( which I don't like due to Snow loads , ICE Build up among other reasons. The Suggestion from the roofer in replacing with EPDM . Do I consider a slightly more aggressive pitch ? Or seriously consider another room above garage. The way I see it , if I am going to invest in a major Labor and Material job. I think I would stand to be much happier with a large room or storage I could enjoy, versus sinking money into an improvement over the garage solely on improving drainage and aesthetic looks?
I am Debating? Would like some suggestions if any?

I guess the first question to ask is can you build an additional room above the garage? Can the existing structure carry the additional load? If it can will the city allow the higher building? Or are you thinking of adding some room trusses?

Tolyn Ironhand addressed a few of the many of the issues that have to be considered if you want to build a room(s) above the garage; I've designed that type of thing 3 or 4 times in my career. Lots to consider.

As to an EPDM roof, I used that many, many times on commercial buildings when I was working. It's a good option to a built-up asphalt roof. The only thing I would say is insist on a roofer with experience and insist on a 60 mil membrane; that 45 mil is just too thin and subject to damage. It's been a while, but as I recall, you MAY be able to go over an existing built-up roof by screwing down a 3/4" thick separation board, then fully adhering the 60 mil EPDM.
