Hi Carl:
Wish I had the time to draw and post but I'm beyond overloaded at the moment. But bearing points for the post supporting the front of the roof run. Usually columns run to the ground but in an application like this we overlap the other two roof overhangs and run the columns into the supporting walls of the walls on either side of the entry path. The two beams supporting the "Top Hat" are then run from the outside wall of the door wall - forward to the two columns you bring up from the walls. The key here is to ensure you have good drainage (1500mm = 59.054" (5'~)) for the rain fall. To this we like to keep as much space between the upper and lower roof, usually 18" to 28". Really depends on the roof slope. Note: Supporting columns require good flashing and saddles to not cause leaking down the road. Do a detail to ensure the contractor gets it right.
When you've done the house, post an jpg. I'd like to see how it looks.Rich Martin
