HVAC supply lines and curbs with leaks at membrane

 Tears and holes in curb flashings allow water to penetrate the membrane and deteriorate the insulation board causing puddling and bigger leaks and insulation issues

  In this photo, you can see signs that water and debris gather in the sagging area of the roof in front of the roof hatch.  This area appears to have been leaking for a while and some repairs have been attempted.

 Here, you can see where termination bar was used to flash this chimney area.  The fasteners are beginning to loosen causing movement and sealant failure.  There does not appear to be a reinforced perimeter strip at the lower change of plane, allowing more movement and trampolining in this area making it much more likely to move or tear.  This area appears to have some leaking issues.
