  For a flat roof what do you think would be a sensible cantilever?
  9x12 in total building footprint 6 - 6x6 posts 3 & 3 timber frame structure with braces.
  The roof would be supported by three laminated beams sitting on the 6x6 posts.  9 2x12's. Lifting a 6x12 up there isn't going to happen.... 
  I can put braces under the cantilever onto the posts if that will allow me to extend it a bit.   I was hoping to get something to sit under in the rain.

  Not sure about sensible, etc. But I was told for TRUSSES on a sloped roof I was looking at, that 25% of total span was doable, as a general rule of thumb.

  Thanks Nate.
  I was thinking it might be more sensible to just do a small overhang and get an awning.
  I have three 6x6s to attach it to, so... it might make more sense than playing arm chair engineer.

  Or put some support brackets on a 45 from the roof to the posts.......

  That was always the plan.  I would put supports under the cantilever for sure.
