Sloping A Mansard Roof But Not Distorting Trim

personalt

I normally do attached multifamiles where we do flat roofs that slope to the back either to a gutter or a roof drain.

I am working now on an addtion to a ranch. the addition has a gambrell roof on the left mansard on the right. see linked picture

the architect has the roof sloping to the right however he shows the top being trimed with a fypon or similar molding.

If I slope that roof the a good amount I should be sloping it at least 3" over the 12'. If I keep the front trim level the roof will be too low on the right side to clear the trim. Architect drawings lablel the slope but dont really show how it affects the trim.

Any idea how to slope this? I was thinking of doing closing it in on 4 sides with a parapet and then use a roof drain but in this town I need to drain into the storn drains rather then into the sewer like the town I normally work in.

I would get some scuppers but not to kean on having to derect lots of water from the flat rough through a hole.

There isnt some bettter way to frame this is there?

Anyone have any ideas on this? Only idea I have now is to set up a parpit wall around the whole thing and maybe use some scuppers which I really dont want to do.. The scuppers will take take all that roofs water and concentrate it in one or two places.

Here's a few thoughts, if any of them help, great....

Hopefully im understanding the drawing.
You could use some roof drains, but instead of connecting it to the sewer, run pipe that will eventually flow out to a gutter. What i'm seeing on the elevation is the exterior portion of the manzanar is pitched, so with scuppers it would allow a concentrated water flow onto that portion of the roof. Might decrease the life span of that portion of roof. Maybe if you could get the pitch close enough to drain the water effectively and not interfere with the trim, instead of using whatever roofing material(like a torch down) you could use something like a dexotex material that wont build up as much.
