Overhang is too short for the deck.

These models are NW-facing. A few of them have these abbreviated rooflines over the deck. Not solely does the unit/deck not get full shade from the overhang, however there’s additionally no gutter hooked up, so the rain simply dumps onto the deck. The constructing additionally has smaller, random overhangs that appear to serve no objective (it has a gutter, although!). One among these is seen to the upper-right of the marked-up overhang. (Faucet image to see it.) Can somebody please clarify the reasoning in these circumstances?
