Finally got started on the addition to our home and thought I would post a few pics as I go. We are expanding the master bedroom, adding another bedroom and adding a two car garage. We are extending one side of the house by removing the existing carport. Pretty much just making the house longer. I will be removing one side of the hip roof that is over the carport and start framing and tying into the existing walls there.
I started pulling off some of the soffit siding that was stapled (?) to the soffit joists and found some other interesting things. One side of the carport has a unsupported single (shouldn’t it be two) 2×12 header spanning about 12′. The front of the carport has two 2×12’s that span about 27′ and are supported by one post in the center. Some of the pics show how far out of plumb the two 2×12 headers are. I looks like the weight of the roof is pushing out the header. The corners of the headers are coming apart, spreading.
The hip rafters don’t extend to the edge and connect to the facia or support the edge of the roof sheathing.
I just started so i’m sure i’ll find other things that may or may not be normal practice.
Please feel free to take a look at the pics and give feedback. I’ll post them in my Picasa web album.

>> The front of the carport has two 2x12's that span about 27' and are supported by one post in the center. << So, what you are actually saying is that the span is roughly 13.5'. Not saying that the construction you describe is at all adequate, just trying to help you with the word "span"....
Thanks Matt. Sorry my goof. Yes, what you said is correct.
I think the clear span is 13.5 but the full span is 27."Put your creed in your deed." Emerson

you are correct. When talking about structural issues in normal residential buildings the full span is usually of no consequence, except maybe in the case of a cantilever.
For example, on a house I recently had framed the designer had the floor set up with a run of joists with a 10.5' span and the next joist run over was a 6.5' span. There was a triple 2x10 girder between the 2. It was cheaper for me to just have them use 18' joists to cover both (clear) spans. Using the 18' boards was of no consequence from a structural standpoint.
My point being that "clear span: is often used interchangeably with "span".
My bad...
