tie to existing structure

we got the addition and the existing structure tied in last week. There was a need to reinforce the roof rafters on the existing house attic to brace from an older remodeling which took out part of the structure to accomodate for a central air and heat unit.

we need to transition between the existing shingle roofing and the new corrugated metal roof of the addition. the distinction between the two materials is important, it's very apparent from the courtyard.
here it is two weeks ago.

As soon as we are dryed in, the walls of the existing structure at the connection will come down.
