Steel lintels over windows and/or doors do not have flashing. Here is how I used to document some of this (feel free to use or adapt to your reporting style) The exposed portion of the lintel can be cleaned and painted, but there’s no way to get to the top of the horizontal flange (where the brick rests), which is the most vulnerable surface. As the lintel corrodes the corrosion expands and will can create the kind of horizontal gap that you see. The lack of flashing, no weep holes, and calking along the front edge are all contributors to lintel corrosion. These are common deficiencies but IMO reportable (they are not readily correctable, sometimes rusting lintels can fail over time - a long time typically). What, I think I do see is: A rusting lintel no indication of flashing at the lintel no weep holes above the lintel caulking on the lintel which shouldn’t be there. I don’t have the full picture and I’m only looking at a picture, but I don’t see any of those indicators in this house. Also, look for signs of distress at the ends of the lintel and the brick below the ends (especially outside corners). Is there any cracking in the veneer over the opening? When the garage door is closed, you can sight along the seam lines as a straight edge (from the side at a shallow angle) which will show you if the lintel is sagging in the center. I’m looking for signs of deflection and distress in the brick veneer.
